Utilization of

Short-Stay

Hospitals

United States, 1984

Annual Summary

This report presents statistics on the

utilization of non-Federal short-stay

hospitals based on data collected through

the National Hospital Discharge Survey

from a national sample of the hospital

records of discharged inpatients. Estimates

are provided by the demographic

characteristics of patients discharged,

conditions diagnosed, and surgical and

nonsurgical procedures performed, and

by geographic region, bed size, and

ownership of hospitals that provided

inpatient care. Measurements of hospital

utilization are given by frequency, rate,

percent, and average length of stay.

Introduction

This report provides national estimates on the utilization

of non-Federal short-stay hospitals during 1984. Data are summarized for selected demographic characteristics of the patients

discharge~ characteristics of the hospitals where the patients

were treated, condhions diagnosed, and surgical and nonsurgical procedures performed.

The statistics in this report are based on data collected by

the National Center for Health Statistics by means of the National Hospital Discharge Survey (NHDS), which is a continuous voluntary survey in use since 1965. The data for the survey

are obtained from the face sheets of a sample of inpatient medical records that are obtained from a national sample of shortstay general and spcialty hospitals located in the United States.

Approximately 192,000 medical records from 407 hospitals

were included in the 1984 survey. A brief description of the

sample design and the sources of data can be found in appendix

I. A detailed report on the design of the NHDS was published

in 1970.’

Types of hospital utilization measurements shown are frequencies, rates, and percent distributions of discharges, days of

care, and average lengths of stay. The estimates are presented

by age, sex, and race of the patients discharged by expected

source of payment, geographic region, bed size, and ownership

of the short-stay hospitals (tables 1-6). Statistics on women

with deliveries (tables 7–8), conditions diagnosed (tables 9-14),

and procedures performed (tables 15–22) also are shown by

patient and hospital characteristics. Data for newborn infants

are included only in the section “Newborn infant discharges.”

Because these data are based on a sample, they may not agree

with data on births published in Vital Statistics of the United

States.

Coding of medical data for patients hospitalized is performed according to the International Classzjication of Diseases,

9th Revision, Clinical A40dzficationz (ICD-9-CM). Earlier

data for 1970-78 were coded according to the Eighth Revision

International C1asslj7cation of Diseases, Adapted for Use in

the United States3 (ICDA). Differences between these two

systems are discussed in appendix I under the section entitled

“Medical coding and edit.” A maximum of seven diagnoses

and four procedures may be coded for each medical record in

the sample. Although diagnoses included in the ICD-9-CM

section entitled “Supplementary classification of external causes

of injury and poisoning” (codes E800-E999) are used by the

NHDS, these diagnoses are excluded from this report. The

conditions diagnosed and procedures performed are presented

here by the major diagnostic chapters and procedure groups of

the ICW9–CM. Within these chapters and groups, some categories of diagnoses and procedures also are shown. These specific

categories were selected primarily because of large frequencies

or because they are of special interest. Residual categories of

diagnoses and procedures, however, are not included in the

tables. More detailed analyses of these data will be presented

in later reports in Series 13 of the Vital and Health Statistics

reports.

Familiarity with the definitions used in the NHDS is important for interpreting the data and for makhg comparisons

with statistical data on short-stay hospital utilization that are

available from other sources. Definitions of the terms used in

this report are presented in appendix H.

Information on short-stay hospital utilization also is collected by another program of the National Center for Health

Statistics, the National Health Interview Survey. Estimates

tlom this survey generally are different from those of the NHDS

because of differences in collection procedures, population sampled, and definitions. Data from the National Health Interview

Survey are published in Series 10 of the Vital and Health

Statistics reports.

1
. During 1984 an estimated 37.2 million patients, excluding

newborn infants, were discharged from non-Federal shortstay hospitals and an estimated 244.7 million days of care

were used.

. The average length of stay for patients discharged from

non-Federal short-stay hospitals was 6.6 days in 1984.

The average length of stay has declined from 7,3 days in

1980 to 6.6 days in 1984—a decline of about 10 percent.

. Nearly one-half of all patients discharged during 1984 expected private insurance to pay for at least part of their

hospitalization.

● The number of discharges was about 29 percent higher in

1984 than in 1965. However, because of the increase in

the size of the population, the discharge rate for the same

period did not vary significantly.

. Females with deliveries was the leading cause of hospitalization during 1984. Of the 37.2 million discharges during

1984, 3.9 million or 10 percent were for females with deliveries.

. Four procedures were performed during 1984 more than 1

million times each: procedures to assist delive~ (2.4 million), endoscopy of the digestive system ( 1.7 million), biopsy

(1.5 million), and computerized axial tomography (CAT

scan) (1. 1 million).

. Approximately 15 percent of all patients who were hospitalized had a principal diagnosis of heart disease (ormalignant neoplasms, but about 50 percent of all deaths that

occurred in short-stay hospitals in 1984 were the result of

these two diseases.

● The number of patients discharged from short-stay nonFederal hospitals during 1984 for the first-listed diagnosis

of cataract dropped from 594,000 in 1983 to 481,000 in

1984—a drop of ahnost 20 percent.

. An estimated 104.3 million diagnoses were recorded for

the 37.2 million discharges from non-Federal hospitals during 1984 for an average of 2.8 diagnoses per discharged

patient.

. Approximately 56 percent of all patients discharged from

short-stay non-Federal hospitals during 1984 had at least

one procedure performed.

● Of the 37.2 million patients discharged from short-stay

non-Federal hospitals during 1984, 2.6 percent were known

to have been discharged dead.

-Utilization by patient

characteristics

Table A shows the selected measures of hospital utilization

for 1965, 1970, 1975, 1980, and 1983. The number of discharges was approximately 29 percent higher in 1984 than in

1965; however, the discharge rate did not vary significantly for

the same period, Smaller increases were noted for days of care.

The number of days of care was only about 9 percent higher

while the rate for 1984 was actually about 11.1 percent lower

in 1984 when compared with 1965.

Although the rate of discharges and days of care decreased

between 1965 and 1970, these differences were not significant.

The decrease was due to an underestimate of hospital utilization

in 1970 because new hospitals that came into the universe of

hospitals were not sampled for NHDS prior to 1972.4 More

information on updating the universe can be found in appendix 1.

The total number and rate of discharges showed no significant drop when 1984 data are compared with 1983 data (table

B). However, there was a significant drop when the number

and rate of days of care for 1984 were compared with those for

1983, In addition, the decrease in discharges and days of care

was signflcant in all four age groups except for the 65 years

and over group. In this age group the days of care figure was

significantly lower than the days of care for 1983, while the

number of dhcharges showed no change. This resulted in a

significant drop in the average length of stay for patients 65

years and over, In 1983 the average length of stay for the 65

years end over age group was 9.7 days while in 1984 it dropped

to 8,9 days—a decrease of 8 percent,

The 37.2 million patients discharged from short-stay hospitals during 1984 included an estimated 14.9 million males

and 22.3 million females (table 1), The rates per 1,000 population were 132 for males and 184 for females, making the rate

for females about 39 percent higher than the rate for males.

The number and rate of discharges always are higher for females

than for males because of the large number of women in their

childbearing years (15+4 years of age) who are hospitalized

for deliveries and other obstetrical conditions. Excluding deliveries, the rate for females discharged was 152, or only about

15 percent higher than the rate for males.

Except for children under 5 years of age and women in

their childbearing yeara, annual rates of discharges increased

consistently with each older age group for both males and females, This pattern of increase also applies to women in their

childbearing years if those who were hospitalized only for deliveries are excluded from the rates. Discharge rates for older

patients (65 years of age and over) compared with those for

younger patients (under 15 years of age) were more than five

times higher for both sexes.

In 1984, male patients used an estimated 104.6 million

days of care in short-stay hospitals, compared with 140.1 million

days of care used by females (table 1). The rate of days of care

per 1,000 population was 924 for males and 1,155 for females,

or about 25 percent higher for femalesthan for males, Differences

between the rates of days of care for each sex were smaller

than for discharges, mainly because the average length of stay

fm about 3,9 million women who were hospitalized for deliveries

was only 3.4 days (table 7). This length of stay compares with

an average length of stay of 7.0 days for males and 6,9 days for

females who were not hospitalized for deliveries.

The annual number of days of care per 1,000 population

increased about 13 times with advancing age from 278 for patients under 15 yeara of age to 3,575 for patients 65 years of

age and over (table 1). The much higher increase in the rate of

days of care than of discharges from the youngest to the oldest

age group was due to long average lengths of stay for persons

65 yean of age and over (8.9 days). The average length of stay

is longer for the aged because of the greater severity of illness

in this group. This situation is indicated by larger proportions

of older than younger patients with incapacitating chronic illness,

and the highest proportion of any age group with multiple diagnoses, both of which result in long average lengths of stay and

high annual rates of days of care.

other. In 1984, 28.4 million patients were identified on the face

sheets of the medical records as white and 5.3 million as all

other. However, race was not reported for an additional 3.4

million patients. Estimates of number and rates of discharges,

days of care, and average lengths of stay are provided. However,

all of the race data should be used with caution due to the notstated category, which for 1984 is approximately 9 percent of

all discharges.

The number of days of care in 1984 totaled 189.0 million

for white patients, 35.8 million for all other patients, and 19.9

million for race not stated (table 2). The average length of stay

was 6.6 days for white patients, 6.7 for all other patients, and

5.8 for patients with race not stated (table 2).

The expected principal source of payment for alll patients

discharged from short-stay hospitals is presented in table 3.

The expected source of payment recorded on the face sheets of

the medical record may not have been the actual source of

payment. For example, a patient admitted to a hospital following an automobile accident may have cited Blue Cross as the

expected source of payment when, in fact, an automobile insurance company ultimately made restitution.

Private health insurance that consists of Blue Cross and

other private or commercial insurance was the expected principal source of payment for approximately 17.4 million discharges from non-Federal shoti-stay hospitals in 1984, about

half of all discharges. Of these 17.4 million discharges, 98.6

percent were under 65 years of age. The remaining 1.4 percent

were 65 years of age and over.

Medicare accounted for 12.2 million discharges (32.8 percent). As expected, 10.8 million (88.3 percent) of thlese were

for patients 65 years and over. Together these two expected

sources of payment accounted for 29.6 million discharges (79.6

percent). Even though patients expecting to pay hospital costs

through Medicare composed only 32.8 percent of all discharges,

they composed 44.0 percent of all days of care. This was due

to the longer hospital stay for patients 65 years and over. This

is reflected in the average length of stay—Medicare patients

were hospitalized an average of 8.8 days, and patients who

expected private insurance to pay their hospital stays averaged

5.4 days. The longest average length of stay was noted for

Medicare patients 65 years of age and over in the Northeast

Region (1 1.3 days). However, lengths of stay of less than 5

days were noted for private insurance patients under 15 years

of age in all regions and for those 15–44 years of a;ge in the

West and South.

During 1984 there were approximately 3.9 million discharges for women with deliveries (tables 7 and 8). (3f these,

37 percent were discharged from hospitals in the Soutlh Region

and 55 percent were discharged from hospitals with 300 beds

or more. Variation in rates per 1,000 civilian population by

region was insignificant, with the exception of the Northeast

Region, which had a rate of 41.2. Rates for all other regions

were about 52–54 per 1,000 population.

The average length of stay for these women was 3.9 days

in the Northeast Region, 3.7 days in the North Central Region,

3.4 days in the South Region, and 2.7 days in the West Region.
Utilization by hospital

characteristics

Discharges from short-stay hospitals by geographic region

in 1984 ranged from 6.4 million in the West Region to 13.5

million in the South Region (table 3). Regional differences in

the number of discharges are accounted for mainly by variations

in population sizes (see appendix I, table III) and, to a lesser

extent, by variations in the discharge rates.

The rates of regional discharges per 1,000 population in

1984 were 139 in the West Region, 149 in the Northeast Regionj

168 in the North Central Region, and 169 in the South Region

(table 5). Among the geographic regions, the North Central

and South Regions had the higher dkcharge rates while the

Northeast and West Regions had the lower discharge rates.

For those under 15 years of age the West had the lowest discharge rates while for those 65 years and over the Northeast

had the lowest discharge rates.

Both the number and the rate per 1,000 population of days

of care were lowest in the West Region. The highest number of

days of care was in the South Region for most of the age and

sex categories, although the highest rates primarily were in the

North Central and the Northeast Regions (tables 4 and 5). The

number of days of care for the total population ranged from

36.4 million in the West to 82.3 million in the South Region.

The rate per 1,000 population was 788 days in the West Region,

1,034 days in the South Region, 1J 52 days in the North Central

Region, and 1,169 days in the Northeast Region.

Average lengths of stay by geographic region were 5.7

days in the West Region, 6.1 days in the South Region, 6.9

days in the North Central Region, and 7.8 days in the Northeast

Region (table 4).

The number of patients discharged fkom short-stay hospitals

and days of cme by sex and age of the patients and by geographic

region and bed size of hospitals are shown in table 4. The percent distributions of these data are shown in table C.

Discharges from short-stay hospitals for patients of all ages

were about 40 percent male and 60 percent female in every

hospital bed-size group. Females with deliveries accounted for

about 10 percent of the discharges regardless of hospital size.

However, some variation was found in the distribution of patients

by age. Specifically, as the bed size of the hospital increased,

the percent of patients who were 65 years of age and over decreased from 36 percent for those in the smallest hospitals to

26 percent for those in the largest hospitals. An overall increase

was found in the percent of patients aged 15–44 years from the

smallest to the largest hospitals. The percent of patients under

15 and 45-64 years of age showed no significant differences

with increasing bed size.

Days of care by sex, age, and bed size of hospital were

generally distributed in a fashion similar to discharges (table

C). However, a smaller pattern of days of care than of discharges was recorded for patients 15-44 years of age regardless

of bed size, and for patients 65 years and over, a larger percent

of days of care than of discharges was recorded for all bed

sizes. The differences for those aged 15-44 years were the

result of short lengths of stay for females with deliveries. However, for those over 65 years of age the differences were the

result of the older patients being hospitalized longer than those

under 65 years of age.

The average length of stay for patients discharged from

shoti-stay hospitals in 1984 increased steadily from 5.3 days

in the smallest hospitals (6–99 beds) to 7.5 days in the largest

hospitals (500 beds or more) (table C). The average length of

stay was slightly longer for males than for females in all hospitals

except for the smaller hospitals. However, when females who

were hospitrdized for deliveries are excludedj the average lengths

of stay for lmth sexes were virtually the same except for the

larger hospitals. Except for patients 15+4 years of age, the

average length of stay increased as the age of the patient increased regardless of the size of the hospital.

Approximately 7 out of 10 patients in non-Federal shortstay hospitals were discharged fmm voluntary nonprofit hospitals

operated by church and other nonprofit groups during every

year the NHDS was conducted. In 1984, voluntary nonprofit

hospitals provided medical care to an estimated 25.7 million

patients, or 69 percent of all patients hospitalized. Hospitals

operated by State and local governments cared for 7.8 million

patients, or 2 I percent of all discharges, and proprietary hospitals operated for profit cared for 3.7 million patients, or 10

percent of all discharges (table 6).

The estimated 244.7 million days of care utilized by patients

in shoti-stay hospitals during 1983 were distributed by ownership of hospitals in the following mannen volunta~ nonprofit,

174.3 million days, or 71 Percenc govemmen~ 47.5 million

days, or 19 percent and proprietary, 22.9 million days, or 9

percent. Average lengths of stay were 6.8 days in voluntary

nonprofit hospitals, 6.1 days in government hospitals, and 6.2

days in proprietary hospitals.

Utilization by diagnosis

First-listed diagnosis

Diseases of the circulatory system ranked first in 1984

among the ICD-9-CM diagnostic chapters as a principal or

frost-listed diagnosis among patients discharged from non-Federal

short-stay hospitals (table 9). These conditions accounted for

an estimated 5.6 million discharges. Other leading ICD–9–

CM diagnostic chapters were diseases of the digestive system

(4.3 million discharges); supplementary classifications, which

include females with deliveries (4.3 million discharges~ injury

and poisoning (3.5 million discharges); dk.eases of the respiratory system (3.4 million discharges); and diseases of the genitourinary system (3. 1 million discharges). About twddrds of

the patients discharged from non-Federal short-stay hospitals

were included in these six ICD-9-CM diagnostic chapters.

It should be pointed out that the estimates for fust-listed

acute myocardial infarction have increased substantially since

1981 because of a decision to reorder circulatory diagnoses

involving acute myocardial infarction. For example, in 1981,

60 percent of acute myocardial infarction diagnoses were firstlisted. In 1984, the first-listed acute myocardial infarction estimate increased to 86 percent because of reordering. The alllisted diagnoses for the 2 years were essentially the same. This

change is discussed more fully in appendix I.

The diagnostic categories presented in this summary report

were selected either because they appear as principal or firstlisted diagnoses with great frequency or because the conditions

are of special interest. Although many of these categories—

such as malignant neoplasms, heart disease, psychoses, and

fractures, all sites—are combinations of more detailed diagnoses, they are presented as single categories without showing

the specific diagnostic inclusions.

It should be noted that even though the total number of

discharges and procedures showed no significant change from

1983 to 1984, there were significant drops in some of the firstlisted diagnoses and all-listed procedures. Two of the more

significant drops occurred in the first-listed diagnosis of essential

hypertension, where the number of discharges dropped from

330,000 in 1983 to 266,000 in 1984—a drop of 19.4 percent—

and cataract, where the number of discharges dropped from

594,000 in 1983to481,000 in 1984—a drop of 19,0 percent.

Other significant drops for first-listed diagnoses were for chronic

disease of tonsils and adenoids, where the number of discharges

dropped from 397,000 in 1983 to 327,000 in 1984—a drop of

17.6 percent—and diabetes, where the number of discharges

dropped from 675,000 in 1983 to 593,000 in 1984—a drop of

12.1 percent.

The most significant drop for procedures occurred for

myringotomy, where the number of procedures dropped from

187,000 in 1983 to 138,000 in 1984—a drop of 26.2 percent—

and diagnostic dilation and curettage of uterus, where the number

of procedures dropped from 632,000 in 1983 to 470,000 in

1984—a drop of 25.6 percent. Other significant decreases in

procedures were for extraction of lens, where the number of

procedures dropped from 630,000 in 1983 to 506,000 in 1984—

a drop of 19.7 percent—and tonsillectomy with or without adenoidectomy, where the number of procedures dropped from

424,000 in 1983 to 348,000 in 1984—a drop of 17.9 percent.

Compensating for the drop in some of the procedures was

a significant increase in the number of miscelkmeous diagnostic

and therapeutic procedures performed. The number of these

procedures performed increased from 6.3 million in 1983 to

7.2 million in 1984—an increase of about 14 percent. In this

group, computerized axial tomography procedures showed the

most significant increase, from approximately 0.9 million in

1983to 1.1 million in 1984—an increase of about 22.2 percent.

There were influences related to hospital admission policies

as well as hospital characteristics that could account for some

of these changes, including the introduction of the prospective

payment system, technological advances, and, Wssibly, the

shifting of patients from an inpatient setting to an outpatient

setting.

The number and rate of discharges, days of care, and average length of stay by selected first-listed diagnoses in 1984 are

presented in table D. These categories accounted for 52 percent

of all patients discharged during 1984 and include the most

frequent first-listed diagnoses for each sex, age, race, region,

and bed-size group. The most common first-listed diagnosis for

most of these groups, as well as for all patients, was females

with deliveries. Excluding this category, the two most frequent

first-listed diagnoses were heart disease and malignant neoplasms

for all groups except patients under 45 years of age, Discussed

below are the most common first-listed diagnoses for the categories not included above.

For patients under 15 years of age, the most frequent i%stlisted diagnoses were chronic disease of tonsils and adenoids;

pneumonia, all forms and acute respiratory infection, except

intluenza. Some other frequent diagnoses for these patients were

noninfectious enteritis and colitis disease of the ear and mastoid

procesw and asthma and fractures, all sites (table 9).

Excluding females with deliveries, the three most frequent

first-listed diagnoses for patients 15-44 years of age were all

abortions, including ectopic and molar pregnancies fractures,

all sites and psychoses. The most common first-listed diagnoses

for patients 45–64 years of age and 65 years of age and over

were heart disease and malignant neoplasms.

For patients other than white the most frequent first-listed

diagnosis, besides deliveries, was heart disease. Other common

diagnoses for this group included malignant neoplasms; all abortions, including ectopic and molar pregnancies; diabetes mellitus; pneumonia, all forms; fractures, all sites; and asthma.

For hospitals with 6–99 beds, the most common first-listed

diagnosis was heart disease, followed by females with deliveries.

Other frequent diagnoses in these hospitals were pneumonia,

all form% fractures, all sites; malignant neoplasms; and noninfectious enteritis and colitis.

The number and rate of patients discharged from shortstay hospitals and average length of stay, by ICD–9–CM diagnostic chapters and selected categories, are presented by age

for 1984 in table 9. Although the estimated rates of discharge

from shoti-stay hospitals generally increased as the age of the

patients increased, especially for patients 15 years of age and

over, some decreases were observed. For example, decreases

in rates between the two oldest age groups (45–64 years and 65

years and over) occurred for the categories of alcohol dependence syndrome, calculus of kkiney and ureter, intervertebral

disc disorders, and sprains and strains of back (including neck).

Moreover, the rates generally decreased with increasing age for

the categories of chronic disease of tonsils and adenoids and

disorders of menstruation and other abnormal bleeding.

The average length of stay increased with increasing age,

especially for patients 15 years of age and over, for most chap

ters and categories of diagnoses. Overall it tended to be higher

for mental disorders (especially psychoses), cerebrcwascular

disease, and alcohol dependence. Other average lengths of stay

over 10 days were for malignant neoplasms, diseases of the

central nervous system, acute myocardial infarctions, and fractures of neck of femur for patients 45 years and over, and fractures, all sites, for patients 65 years and over. Short average

lengths of stay occurred for patients under 45 years with a firstlisted diagnosis of chronic disease of tonsils and adenoids and

for patients 15–44 years who are admitted for abortions, including ectopic and molar pregnancies, and sterilization.

Data on discharges, rates of discharges, and average lengths

8
of stay for patients discharged from short-stay hospitals by sex

and race are presented by diagnostic chapters and selected categories of first-listed diagnosis in table 10.

Rates of discharges per 10,000 population were similar

for the two sexes for most of the diagnostic chapters and categories shown. However, males had significantly higher rates

than females for the categories of alcohol dependence syndrome,

acute myocardial infarction, other ischemic heart disease, inguinal herni~ calculus of kidney and ureter, intracranial injuries

(excluding those with skull fracture), and lacerations and open

wounds. For females, higher rates occurred for the categories

of benign neoplasms and neoplasms of uncertain behavior and

unspecified nature, diabetes mellitus, catarac~ noninfectious

enteritis and colitis, cholelithiasis, arthropathies and related

disorders, and persons admitted for sterilization.

Seventy-seven percent of all patients discharged were white,

14 percent were all other races (including black), and 9 percent

did not state race in the medical record. However, the racial

distribution of patients for some diagnostic categories was significantly different from that of all patients. For example, the

percents were higher for white patients discharged with a firstIisted diagnosis of atherosclerotic heart disease (87 percent)

and diverticula of intestine (87 percent). It was lower for patients

with a diagnosis of alcohol dependence (59 percent), abortions

and ectopic and molar pregnancies (61 percent), and lacerations

and open wounds (65 percent). For all other races it was higher

for abortions and ectopic and molar pregnancies (3 I percent)

and anemias (30 percent).

Information on patients discharged from short-stay hospitals by geographic region is shown in table 11. The number of

discharges ranged from 13.5 million in the South Region to 6.4

million in the West Region. The North Central Region had 9.9

million discharges while the Northeast Region had 7.4 million

discharges. The South Region had the largest number of discharges for most categories. One major exception to this was

for mental disorders where the number of discharges was 535,000

for the North Central Region and only 469,000 for the South

Region. In 1984, the number of discharges per 1,000 population

was 139 in the West Region. 149 in the Northeast Region, 168

in the North Central Region, and 169 in the South Region. The

diagnostic categories for which variations in the rates were the

largest were malignant neoplasms, alcohol dependence syndrome, heart disease, and females with deliveries.

Average length of stay ranged from 7.8 days in the Northeast Region to 5.7 days in the West Region. The North Central

Region had 6.9 days while the South Region had 6.1 days. The

average length of stay was longest in the Northeast Region for

most categories. However, one notable exception was mental

disorders, where the average length of stay was 13.7 days in

the North Central Region and 12.0 days in the West Region.

During 1984, the number of patients discharged fkom shortstay hospitals and the average lengths of stay are shown by bed

size of hospital and diagnostic category in tables 12 and 13,

respectively. Females with deliveries, and heart disease ranked

as the highest categories for first-listed diagnosis in hospitals of

all sizes.

The proportions of some diagnostic conditions treated in

hospitals varied according to the size of the hospital. Greater

proportions of patients were treated in the smallest hospitals

(6-99 beds) for diseases of the respiratory system (table E).

On the other hand, greater proportions of discharges were from

the largest hospitals (500 beds or more) for neoplasmy diseases

of the nervous system and sense organs; complications of pregnancy, childbirth, and the puerperiurn, congenital anomalies;

certain conditions originating in the perinatal pet-id, and sup

plemental classifications.

For the most part, the average length of stay for the diagnostic chapters and categories followed the same patterns as

the overall average lengths of stay for each region and bed size

of hospital. That is, short hospital stays were more common in

the West Regio~ long stays occurred more frequently in the

Northeast Region. Similarly, the average length of stay generally increased as the size of the hospital increased. An exception

to this occurred for the diagnostic category alcohol dependence

syndrome. For this diagnosis, the longest average lengths of

stay were in hospitals with 100– 199 beds (13.8 days).

All-listed diagnoses

An estimated 104 million diagnoses were recorded for the

37.2 million inpatients of non-Federal short-stay hospitals in

1984 (table 14) for an average of 2.8 diagnoses per discharged

patient. The average number of diagnoses per discharge increased from years prior to 1979 because of changes that were

made in the way data are tabulated. Starting in 1979, up to

seven diagnoses per discharge now are coded and tabulated on

the NHDS data filq prior to that time, up to five diagnoses

were coded. In addition, the ICD-9-CM, which is the classification scheme used for coding medical data since 1979, has

inherent in it a certain amount of “double coding”; the classification used prior to 1979 does not. For example, females with

deliveries all receive one additional diagnostic code that indicates the outcome of their delivery (single liveborm twins, both

Iiveborm and so forth); however, this was not the case prior to

1979.

The average number of diagnoses per discharge varied

only slightly by sex and race of the patient and by region and

bed size of the hospital. For each of these categories, the average

was 2.6–3.0 diagnoses per patient. A larger variation occurred

by age. The average number of diagnoses per discharge for the

age groups under 15 years, 1544 years, 45–64 years, and 65

years and over was 1.9,2.2,2.9, and 3.8, respectively.

Diseases of the circulatory system ranked first among the

ICD–9–CM diagnostic chapters for all-listed diagnoses, with

20.4 million diagnoses. This was followed by diseases of the

digestive system (9.0 miilion); supplementary classifications

(8.1 million} diseases of the genitourinary system (7.8 million);

and diseases of the respiratory system (7.7 million). These five

ICD-9-CM chapters accounted for approximately51 percent

of all-listed diagnoses in 1984.

10
Utilization by procedures

One or more procedures were performed for an estimated

20,9 million of the 37,2 million inpatients discharged from shortstay hospitals during 1984, A total of 36,2 million procedures,

or an average of 1,7 per patient who underwent at least one

procedure, were recorded in 1984 (table 15),

These figures are higher than those reported prior to 1979

because changes were made in the tabulation and coding of

data for the NHDS that resulted in the reporting of a greater

number of procedures. Beginning in 1979 more procedures,

both in number per patient and in type of procedure, were coded,

Specifically, starting in 1979 up to four procedures, instead of

only three, were coded for each discharge. Furthermore, only

figures for “surgical” operations were published in the past.

However, since 1979 the totrd number includes many additional

nonsurgical procedures, (See appendix I under the section entitled “Medical coding and edit” and appendix 11 under the

section entitled “Surgical and nonsurgical procedures” for more

information on the differences between coding the ICDA and

the ICD-9-CM.)

The number and percent of patients with surgical and nonsurgical procedures in 1984 and the number and percent of

patients with at least one surgical procedure are shown in table

F. About 56 percent of the patienta discharged had some procedure, including diagnostic and nonsurgical procedures. Some

variations in the proportions, however, occurred by age and

sex of the patient geographic regio~ and bed size of the hospital,

Patients 15-44 years of age had the highest proportion of all

the age groups with procedures (64 percent). Women had more

procedures than men (58 percent compared with 53 percent),

primarily because of those relating to childbirth. The proportion

of patients with one or more procedures increased with the size

of the hospital, from 36 percent in hospitals with 6-99 beds to

about 67 percent in hospitals with 500 beds or more.

Approximately 54 percent of the patients with procedures

had only one operation or nonsurgical procedure during their

hospitalization (table G). About 27 percent of the patients had

two procedures, about 11 percent had three, and about 8 percent

had four or more, By age, patients under 15 years of age had

the lowest proportion of multiple procedures (34 percent) and

those 45-64 years and 65 years of age and over had the largest

proportion (53 and 54 percent, respectively). About 40 percent

of the patients discharged from the smallest hospitals had more

than one procedurq atnmt 47 percent of the patients discharged

from hospitals of all other sizes had two or more procedures

during their hospitalization.

Procedures are grouped in the detailed tables of this report

by the 16 mqjor ICD-9-CM groups, Selected procedures withh

these groups are presented by specific categories within the

detailed tables as well as in the text tables. Some of these

categories-such as repair of inguinal hernia, prostatectomy,

and hysterectomy-are presented as single categories although

they may be divided into more precise subgroups,

Miscellaneous diagnostic and therapeutic procedures (7.2

million) ranked fwst among the surgical and nonsurgical procedures performed during 1984, Other leading ICD-9-CM groups

were operations on the digestive system (5,9 million), obstetrical procedures (3.9 million), operations on the musculoskeletal

system (3.7 million), and operations on the female genital organs

(3.5 million). About two-thirds of the procedures performed in

1984 were included in these five mqjor groups.

The number and rate of all-listed procedures in 1984 by

selected ICD-9-CM categories am shown in table H, The categories presented in this table include procedures that were performed frequently during the year. Many of the procedures

included in this table are diagnostic and nonsurgical procedures

that were not published by the NHDS prior to 1979, such as

endoscopy on the digestive system, endoscopy of the urinary

system through natural orifice, artenography and angiocardiography using contrast material, diagnostic uhra.aoun~ and radioisotope scan. Over one-half million of each of these procedures

were performed during 1984.

Data for the more traditional leading surgical operations

are shown in table H. Some of the most frequently performed

surgeries, of which 500,000 or more were performed in 1984,

included cesarean section, hysterectomy, excision or destruction of lesion or tissue of skin or subcutaneous tissue, cardiac

catheterization, arthroplasty ofjoints, and extraction of lens.

The estimated 36.2 million procedures performed in 1984

are presented for the ICD-9-CM major groups and selected

categories by age, sex, race, and region in tables 15, 17, 19,

and 20, respectively. The corresponding rates by age, *x, and

region are shown in tables 16, 18, and21, respectively.

Of the 36.2 million procedures performed during 1984,41

percent were performed on patients 15-44 years of age, while

only 6 percent were performed on patients under 15 years of

age. The most common procedure performed on patients under

15 years was tonsillectomy with or without adenoidectomy,

and for those 15-44 years of age it was episiotomy without

forceps and vacuum extraction. The most common procedure

for the 45-64 years age group was arteriography and angi~

cardiography using contrast materia~ and for those 65 years

and over the most common procedures were endoscopies through

natural orifice and lens extraction.

The rate of procedures per 1,000 population increased

with advancing age from a rate of 39 for patients under 15

years to 378 for patients 65 years of age and over (table J).

Except for females 15-44 years of age, the rates for both sexes

also increased as age increased. The rate for females 15-44

years of age was higher than that for females 45-64 years of

age because of the large number of females 1544 years of age

operated on for obstetrical and gynecological conditions.

Of the 36.2 million procedures performed during 1984,

about 14.4 million were for males and 21.8 were for females.

The corresponding rates per 1,000 population were 154 for

both sexes, 127 for males, and 180 for females. Of the procedures shown in table 17, the most common for males were

arteriography and angiocardiography using contrast material,

endoscopies through natural orifice, and CAT scans. For females, the most frequently performed procedures were episiotomy without forceps and vacuum extraction, cesarean section,

hysterectomy, CAT scans, and diagnostic ultrasound.

The distribution of procedures by race is shown in table

19. Seventy-eight percent of all procedures were performed on

white patients, 13 percent were performed on all other races

(including black), and 9 percent were performed on patients

with no race stated. Generally, the percent distribution of total

procedures for white patients was similar to that for all other

patients and those with race not stated. However, the percents

for all other patients were higher for obstetrical procedures and

operations on the female genital organs.

The number of procedures for patients discharged from

short-stay hospitals by procedure catego~ and geographic region

is presented in table 20, and the corresponding rates are shown

in table 21. The rate of procedures per 1,000 population was

176 in the North Central Region, 151 in the Northeast Region,

148 in the South Region, and 142 in the West Region. Rates

were highest in all regions for operations on the digestives ystem,

the female genital organs, the musculoskeletal system, obstetrical procedures, and miscellaneous diagnostic and therapeutic

procedures.

NOTE A maximum of 4 procedures was coded for sachpatient discharged.

where the procedure was performed is shown in table 22. Operations on the digestive system were observed to rank highest of

all-listed procedures in hospitals with less than 200 beds. The

most common procedures for hospitals of 500 beds or more

were miscellaneous diagnostic and therapeutic procedures and

operations on the digestive system.

The percent distributions of the major groups of procedures

by bed size of hospital are shown in table K. Hospitals with

300 beds or more treated an estimated 49 percent of the patienta

hospitalized during 1984, but performed about 56 percent of

the procedures. Procedures for which large percents were performed in hospitals with 300 beds or more were operations on

the cardiovascular system (73 percent). Other groups having

60 percent or more of the procedures performed in hospitals

with 300 beds or more were operations on the nervous system

(64 percent), operations on the endocrine system (64 percent),

operations on the hernic and lymphatic system (62 percent),

operations on the respiratory system (60 percent), and miscellaneous diagnostic and therapeutic procedures (60 percent).

Deaths in short-stay hospitals

In 1984, 96.3 percent of patients, excluding newborn infants, who were discharged from short-stay hospitals were dis

charged alive, 2.6 percent were discharged dead, and for 1.1

percent a discharge status was not ascribed. Of the estimated

957,000 patients who died, 49.8 percent were male and 50.2

percent were female (table L). As expected, patients 65 years

and over accounted for the majority of hospital deaths-72.0

percent. Patients under 65 years of age accounted for 28.0

percent of the deaths. The 957,000 who were discharged dead

fkom these hospitals represented about 47 percent of all persons

who died during 1984.5

The hospital fatality rate is the number of deaths divided

by the number of total discharges multiplied by 100. This is a

conservative rate because the formula assumes that all those

patients whose discharge status was not stated were discharged

alive. A fatality rate of 2.6 has been computed for patients in

1984. The rate for males was higher than that for females—3.2

for males compared with 2.2 for females.

The 65 years and over age group had a hospital fatality

rate of 6.1 per 100 discharges; however, patients under 65 years

of age had a fatality rate of 1.0. The fatality rates for males and

females did not vary significantly from each other in each of

the age groupings.

The estimated number of hospital deaths and hospital fatality rates for patients under 65 years of age and for those 65

years and over are shown for selected conditions in table M.

These data are not synonymous with data for underlying cause

of death as reported in Vital Statistics of the United States. Of

the estimated 957.000 deaths in short-stay hospitals, 71 percent are accounted for by the diagnostic groupings shown in

table M. Of these, heart disease and malignant neoplasms accounted for nearly one-half (477,000) of all deaths in shortstay hospitals.

For specific diagnoses, the highest fatality rates were for

acute myocardial infarction, with a rate of 16.1 per 100 discharges, and nephrhis, nephrotic syndrome, and nephrosis, with

a rate of 14.7 per 100 discharges. Other high fatality rates were

for chronic liver disease rmd cirrhosis ( 11.9 per 100 discharges),

cardiac dysrhythmias (11.3 per 100 discharges), and malignant

neoplasms (10.5 per 100 discharges).

The average length of stay for patients discharged from

short-stay hospitals. by discharge status and sex, is shown in

table N. The average stay for all patients discharged ‘was 6.6

days. Patients discharged alive had an average stay of 6,4 days,

compared with an average stay of 12.6 days for patients who

died in the hospital.

Patients under 65 years of age, discharged alive, stayed an

average of 5.5 days; however, those who died had an average

stay of 12.6 days. The hospital stay for patients 15–44 years of

age who died was 2.6 times as long as for those who were

discharged alive (12.5 and 4.9). The difference in length of

stay was much smaller for patients 65 years and over—8.7

days for those discharged alive and 12.6 days for thc)se who

died.

Newborn infant discharges

The number, percent distribution, and average length of

stay of newborn infants discharged from short-stay hospitals,

by sex and geographic region, are shown in table O. Because

these data are based on a sample, they may not agree with data

on births published in Vital Statistics of the United States.

The estimated 3.9 million newborn infants were equally divided

between the sexes.

About 38 percent ( 1.4 million) of newborn discharges were

from the South Region and approximately 24 percent (0.9 million) were from the North Central Region. The percents of

discharges were approximately 20 percent (0.8 million) for the

West Region and 18 percent (0.7 million) for the Northeast

Region. The average length of stay was 4.1 days in the Northeast Region and 2.9 days in the West Region. The average

length of stay was 3.9 days in the North Central Region and

3.7 days in the South Region. About 70 percent of the 3.9

million newborn infants discharged from short-stay hospitals

were” well. ” A well infant is defined as one who does not have

an illness or risk-related diagnosis (table P).

The estimated 1.2 million sick infants (30 percent of all

newborn) had at least one diagnosis in addition to the newborn

diagnosis. Some of these additional diagnoses are shown in

table Q. About 0.5 million (29 percent) of the diagnoses were

for jaundice. The next three leading diagnoses were respiratory

conditions, prematurity, and congenital anomalies. These four

diagnoses accounted for about 61 percent of all sick newborn

diagnoses. Males accounted for 58 percent of the respiratory

conditions, 58 percent of the congenital anomalies, 53 percent

of the jaundice, and 53 percent of the prematurity diagnoses.

Of the 1.2 million sick newborn infants, there were 22 percent

more boys than girl~ the boys also had 3 I percent more diagnoses than the girls did.

Well newborn infants had an average hospital stay of 2.9

days, and there was no difference in the length of stay by sex

(table P). This table further demonstrates that sick :newbom

infants stay almost twice as long as well infants (5.6 versus 2.9

days) and account for 46 percent of the newborn patient days.

although they constitute only 30 percent of newborn infants.

Technical notes on methods

Statistical design of the National

Hospital Discharge Survey

Scope of the survey

The National Hospital Discharge Survey (NHDS) consists

of patients discharged fmm noninstitutional hospitals, exclusive

of military and Veterans Administration hospitals, located in

the 50 States and the District of Columbia. Only hospitals with

six beds or more for patient use and those in which the average

length of stay for all patients is less than 30 days are included

in the survey. Discharges of all patients from Federal hospitals

are excluded.

Sample size

The Master Facility Inventory of Hospitals (MFI) is the

universe from which the NHDS sample is drawn. A detailed

description of the development, contents, maintenance plans,

and assessment of coverage was published in 1965.6

The original universe for the survey consisted of 6,965 shortstay hospitals contained in the 1963 MFI. This universe is

updated periodically (table I). Data on the universe of shortstay non-Federal hospitals is now obtained ffom the American

Hospital Association. The distribution of the current hospitals

in the American Hospital Association universe’ and NHDS

sample of in-scope hospitals for 1984 is given by bed size and

geographic regions in table II.

The sample for 1984 consisted of 553 hospitals. Of these,

86 refused to participate and 60 were out of scope either because the hospital had gone out of business or because it failed

to meet the definition of a shoti-stay hospital. Thus, 407 hospitals participated in the survey during 1984 and provided approximately 192,000 abstracts of medical records.

49
Sample design

All hospitals with 1,000 beds or more in the universe of

short-stay hospitals were selected with certainty in the sample.

All hospitals with fewer than 1,000 were stratified, the primary

strata being the 24 size-by-region classes shown in table II.

Within each primary stratum, the allocation of the hospitals

was made through a controlled selection technique so that

hospitals in the sample would be distributed properly with

regard to ownership and geographic division. Sample hospitals

were drawn with probabilities ranging from certainty for the

largest hospitals to 1 in 40 for the smallest hospitals.

The witiln-hospital sampling ratio for selecting sample

discharges varied inversely with the probability of hospital

selection. The smallest sampliig fraction of dkcharged patients

was taken in the largest hospitals, and the largest fraction was

taken in the smallest hospitals. This sampling was done to

compensate for hospitals that were selected with probabilities

proportionate to their size class and to ensure that the overall

probability of selecting a dkcharge would be approximately the

same in each size class.

In nearly all hospitals, the daily listing sheet of discharges

was the frame from which the subsamples of discharges were

selected within the sample hospitals. The sample dkcharges

were selected by a random technique, usually on the basis of

the terminal digit(s) of the patient’s medical record number that

was assigned when the patient was admitted to the hospital. If

the hospital’s daily discharge listing did not show the medical

record numbers, the sample was selected by starting with a

randomly selected discharge and taking every kth discharge

thereafter.

Data collection and processing

Data collection

Depending on the study procedure agreed on with the

hospital administrator, the sample selection and the transcription of information from the hospital records to abstract forms

were performed by either the hospital staff or representatives of

the National Center for Health Statistics (NCHS) or by both,

In about 50 percent of the hospitals that participated in the

NHDS during the year, this work was performed by the medical

records department of the hospital. In the remaining hospitals,

the work was performed by personnel of the U.S. Bureau of the

Census acting for NCHS.

Survey hospitals used an abstract form to transcribe data

from the hospital records. The form provides space for recording

demographic data, admission and discharge dates, zip code of

the patient’s residence, expected sources of payment, disposition of the patient at discharge, and information on discharge

diagnoses and surgical operations or procedures (figure I). All

discharge diagnoses and procedures were listed on the abstract

in the order of the principal one, or the first-listed one if the

principal one was not identified, followed by the order in which

all other diagnoses or procedures were entered on the face sheet

of the medical record,

Completed abstract forms for each sample hospital were

shipped, along with sample selection control sheets, to a Census

Regional 0t13ce. Every shipment of abstracts was reviewed

and each abstract form was checked for completeness. Abstracts

then were sent to NCHS for processing.

Medical coding and edit

The medical information recorded on the sample patient

abstracts was coded centrally by the NCHS staff. A maximum

of seven diagnostic codes were assigned for each sample abstracc in addition, if the medical information included surgical

or nonsurgical procedures, a maximum of four codes for these

procedures were assigned. Following conversion of the data on

the medical abstract to computer tape, a final medical edit was

accomplished by computer inspection runs and a review of rejected abstracts. If the sex or age of the patient was incompatible

with the recorded medical information, priority was given to

the medical information in the editing decision.

NHDS medical coders code from abstracts of medical

records in the order the diagnoses and procedures are entered.

For most abstracts, this coding procedure is relatively free of

problems. It was noted, however, that acute myocardial infarction frequently was not the lead entry in a group of circulatory

diagnoses. For example, the patient’s record may have arteriosclerosis listed first and arteriosclerotic heart disease listed

second with acute myocardial infarction listed third. If the usual

procedure were followed as it was until 1982, acute myocardial

infarction would be coded in third place and retrievable only

under the heading of all-listed diagnoses. A decision was made

to reorder some acute myocardial infarction diagnoses. The

new procedure, based on accepted medical coding practice,

states that whenever an acute myocardial infarction is encountered with other circulatory diagnoses and is other than

the fwst entry, it should be reordered to first position.

The system currently used for coding the diagnoses and

procedures on NHDS sample patient abstracts is the International Classij7cation of Diseases, 9th Revision, Clinical

Modzficationz (ICD-9-CM). Earlier data for 1970-78 were

coded according to the Eighth Revision International Classij7cation of Diseases, Adapted for Use in the United States3

(ICDA), with some modifications. These modifications, which

were necessary because of incomplete or ill-defined terminology

in the abstracts, are presented elsewhere.8 It has not been

necessary, however, to modify the ICD-9–CM for use in the

NHDS.

Both the ICDA and the ICD–9-CM are divided into two

main sections: diseases and injuries, and surgical and nonsurgical procedures. However, many differences exist between the

two classifications. These differences are discussed in a previous

report.g

Some ICD–9-CM diagnostic codes cannot appear alone;

they must appear with another diagnostic code. Specifically,

the following codes cannot be first-listed: 320.7, 321.1-321,8,

323.0-323.4, 323.6--323.7, 330,2-330,3, 331.7, 334.4,

336.2-336.3, 337.1, 357.1-357.4, 358.1, 359.5-359.6,

and 645.0 –676.9 with a fiflh digit of 1 or 2 or 650 (indicating

delivery) must have a code V27 .O-V27.9 as a first-listed diagnosis. Conversely, every dkcharge with a first-listed diagnosis

of V27.O–V27.9 also must have one of these delivery codes.

Prior to 1979, data on radiotherapy and physical medicine

and rehabilitation (ICDA codes R1 -R4) and some obstetrical

procedures were not collected by means of the NHDS. The

obstetrical procedures not coded were artificial rupture of

membranes, external, internal, and combined version; outlet

and low forceps delivery with and without episiotomy; and

episiotomy (ICDA codes 75 .0–75.6 and 75.9). In addition,

data for diagnostic endoscopy, radiography, and other nonsurgical procedures (ICDA codes A4–A9 and R9), although coded,

were not published. Starting with 1979 data, however, the

procedures coding has followed the guidelines of the Uniform

Hospital Discharge Data Set (UHDDS).]O,l 1 The UHDDS

is a minimum data set of items uniformly defined and abstracted

from hospital medical records. These items were selected on

the basis of their continuous usefulness to organizations and

agencies requiring hospital information.

According to the UHDDS guidelines, all procedures are

allocated into one of four classes. Classes 1–3 consist of procedures that carry an operative or anesthetic risk or require

highly trained personnel, special facilities, or special equipment. Class 4 procedures do not meet these criteria. See

appendix II for the procedure codes included in these classes.

Until 1983, the only Class 4 procedures coded in the

NHDS were circumcision (ICD–9–CM code 64.0), episiotomy

(code 73.6), and removal of intrauterine contraceptive device

(code 97.7 1). The coding of additional Class 4 procedures,

listed in appendix II, that are used in the assignment of diagnosis-related groupings (DRG’s), was begun in mid-1983.

DRGs, developed at the Yale School of Organization and

Management, are being used by the Health Care Financing

Administration, some States, and some third party payers to

reimburse hospitals for inpatient care. A report has been published on the conversion of NHDS data to DRG’s.12

Presentation of estimates

Grouping of diagnoses and procedures

In this report the diagnostic chapters, the broadest groupings

of diseases and injuries shown, correspond to ICD-9–CM

chapters 1– 17 and the Supplementary classification of factors

influencing health status and contact with health services. The

NOTE: A list of references follows the text.

diagnostic categories, the most detailed groupings of diseases

and injuries shown, are subsets of the major groups or chapters.

The titles and the ordering of the categories in the tabular list

developed for the NHDS follow the format of the ICD-9-CM

tabular list as closely as possible.

The procedure groupings used in this report are the groups

numbered 1– 16 in the ICD–9–CM section entitled “Procedure

Classification.” Specific categories of operations or procedures,

the most detailed of these groupings shown, are subsets of the

major groups and are based on the 4-digit codes provided by

the ICD-9-CM.

In developing the tables of diagnoses and of procedures,

an effort was made to maximize specificity of the conditions or

procedures consistent with clarity of characterization,, the frequency of their occurrence, and their interest.

Patient characteristics not stated

The age and sex of the patient were not stated on the hospital records (the face sheet of the patient’s medical record) for

about 1 percent of the discharges. Imputations of these missing

items were made by assigning the patient an age or sex consistent with the age or sex of other patients with the same diagnostic code.

During 1984, 8.6 percent of the records had no race identified in the hospital records.

If the dates of admission or discharge were not given and

could not be obtained from the monthly sample listing sheet

transmitted by the sample hospital, a length of stay was imputed

by assigning the patient a length of stay characteristic of the

stays of other patients of the same age. During 1984, only 0.11

percent of the records were missing the date of admission or

discharge.

Rounded numbers

Estimates of the numbers of inpatient discharges, days of

care, discharges with procedures, all-listed diagnoses, and alllisted procedures have been rounded to the nearest thousand

for tabular presentation. Therefore, detailed figures within the

tables do not always add to totals. Rates and percents were

calculated on the basis of unrounded figures and will not necessarily agree with computations made from the rounded data.

Population estimates

The population estimates used in computing rates are from

published and unpublished estimates for the U.S. civilian population on July 1 of the data year provided by the U.S. Bureau

of the Census. The estimates by age and sex and by geographic

region are presented in table III and are consistent with the

population estimates published in Current Population Reports,

Series P–25.

Although the civilian noninstitutionalized population was

used prior to 1981, it has been determined that the civilian

population is more appropriate to use for the NHDS as persons

in institutions usually are hospitalized in short-stay lhospitals.

This is true especially for elderly residents of nursing lhomes. A

comparison of NHDS rates based on the civilian population

with the civilian noninstitutionalized population is available in

another publication. 13

Reliability of estimates

Estimation

Statisticsproduced by the NHDS are derived by a complex

estimating procedure. The basic unit of estimation is the sample

inpatient discharge abstract. The estimating procedure used to

produce essentially unbiased national estimates in the NHDS

has three principal components: inflation by reciprocals of the

probabilities of sample selection, adjustment for nonresponse,

and ratio adjustment to fixed totals. These components of estimation are described in appendix I of two earlier publications. 14.15

Measurement errors

As in any survey, results are subject to nonsampling or

measurement errors, which include errors because of hospital

nonresponse, missing abstracts, information incompletely or

inaccurately recorded on abstract forms, and processing errors.

Some of these errors were discussed in an earlier section entitled

“Patient characteristics not stated.”

The Institute of Medicine (IOM) has conducted three

studies on the reliability of hospital abstract data collection;

the most recent study was on the NHDS. The IOM NHDS stidy

was performed by using data coded according to the ICDA;

however, some of the findings are relevant to the 1981 NHDS

data even though these data were coded according to the

ICD–9–CM. Of special interest to this report is the finding

that, in a number of cases, the first-listed diagnosis in the

NHDS was not the principal diagnosis as determined by IOM

after a study of the entire medical record. For example, when

diagnoses at the ICDA class level were examined, the principal

diagnosis from IOM matched the first-listed diagnosis from the

NHDS in approximately 86 percent of the cases. Detailed accounts of this and other IOM findings have been published.16-18

Sampling errors

The standard error is primarily a measure of the variability

attributed to a value obtained from a sample as an estimate of a

population value. In this report it also reflects part of the

measurement error. The value that would have been obtained if

a complete enumeration of the population had been made will

be contained in an interval represented by the sample estimate

plus or minus 1 standard error about 68 out of 100 times and

plus or minus 2 standard errors about 95 out of 100 times.

The relative standard error is obtained by dividing the

standard error by the estimate. The resulting value is multiplied

by 100, which expresses the standard error as a percent of the

estimate.

The standard error of one statistic generally is different

from that of another, even when the two come from the same

survey. To derive standard errors that would be applicable to a

wide variety of statistics that could be prepared at a moderate

cost, a number of approximations are required. As a result, the

figures in this appendix provide general relative standard errors

for a wide variety of estimates rather than the specific error for

a particular statistic.

Approximate relative standard errors and standard errors

have been prepared for measuring the variances applicable to

(1) estimates of the discharges or first-listed diagnoses, and

days of care for patient characteristics (for example, age, sex,

and race) and hospital characteristics (for example, region, bed

size, and ownership), and patient characteristics crosstabulated

NOTE A list of references follows tbe text.

by hospital characteristics; and (2) estimates of all procedures

performed by the specific procedure for the patient characteristics age, sex, and race and the hospital characteristics geographic region and bed size of hospital.

The relative standard errors applicable to patients discharged or first-listed diagnoses, all-listed diagnoses, days of

care, and procedures are provided in figures II-IV. The curves

for relative standard errors of the estimates in each figure relate

to the variables by which estimates are presented in this report.

In these figures, curves are shown for variables the relative

standard errors of which are different from those in the curve

for “All other variables,” which is relevant to most of the estimates, For example, one curve is applicable only to estimates

of discharges from voluntary nonprofit hospitals, a second curve

is concerned with discharges from hospitals by bed size, and a

third curve pertains to estimates of days of care in proprietary

hospitals,

The selection of the appropriate relative standard error curve

is made as follows:

patient and hospital characteristics:Relative standard

errors of the estimated number of days of care are obtained

from the curves in figure 111.

Procedures:Relative standard errors for procedures are

obtained from the curve in figure IV.

The presentation of estimates for the NHDS is based on

relative standard error of the estimate and the number of

sample records on which the estimate is based (referred to as

the sample size), Estimates are not presented unless a reasonable assumption regarding the probability distribution of the

sampling error is possible, The Central Limit Theorem is used

to determine the distribution of the sampling errors, The {Central

Limit Theorem states that, given a sufficiently large sample

size, the sample estimate is approximately normally distributed

and approximates the population estimate,

Based on consideration of the complex sample demignof

the NHDS, the following guidelines are used for presenting

NHDS estimates:

1. If the sample size is less than 30, the value of the estimate

is not reported. Only an asterisk (*) is shown in the tables,

2, If the sample size is 30-59, the value of the estimate is

reported. but should be used with caution, The estimate is

preceded by an asterisk (*) in the tables,

3. If the sample size is 60 or more but the relative standard

error is over 30 percent, the estimate is reported but should

be used with caution, The estimate is preceded by sn asterisk

(*) in the tables,

Tests of significance

In this report, the determination of statistical inference is

based on the t-test with a critical value of 1.96 (0.05 level of

significance), Terms relating to differences, such as “higher”

and “less,” indicate that the differences are statistically significant. Terms such as “similar” or “no difference” mean that

no statistically sign~lcmit difference exists between the estimates being compared. A lack of comment on the dlflerence

between any two estimates does not mean that the difference

was tested and found to be not significant,

Definitionsof terms

Hospitals and hospital characteristics

Hospitals—Shoti-stay special and general hospitals have

six beds or more for inpatient use and an average length of stay

of less than 30 days. Federal hospitals and hospital units of

institutions are not included.

Bed size of hospital—Size is measured by the number of

beds, cribs, and pediatric bassinets regularly maintained (set

up and staffed for use) for patients; bassinets for newborn infants

are not included, In this report the classification of hospitals by

bed size is based on the number of beds at or near midyear as

reported by the hospitals.

Type of ownership of hospital—The type is determined by

the organization that controls and operates the hospital. Hospitals are grouped as follows:

● Voluntary nonprofit-Hospitals operated by a church or

another nonprofit organization.

. Governrnent-Hospitals operated by State or local governments.

. Proprietary-Hospitals operated by individuals, partnerships, or corporations for profit.

Patient—A person who is formally adrnhted to the inpatient

service of a short-stay hospital for observation, care, diagnosis,

or treatment is considered a patient. In this report the number

of patients refers to the number of discharges during the year,

including any multiple discharges of the same individual from

one short-stay hospital or more. Infants admitted on the day of

birth, directly or by transfer from another medical facility, with

or without mention of a disease, disorder, or immaturity, are

included. All newborn infants, deflmed as those admitted by

birth to the hospital, are excluded from the tables in this report

except those in the newborn section of the report. The terms

“patient” and “inpatient” are used synonymously.

Newborn infant—A newborn infant is defined as a patient

admitted by birth to a hospital.

Discharge—Discharge is the formal release of a patient by

a hospitak that is, the termination of a period of hospitalization

by death or by disposition to place of residence, nursing home,

or another hospital. The terms “discharges” and “patients discharged” are used synonymously.

Discharge rate—The ratio of the number of hospital discharges during a year to the number of persons in the civilian

population on July 1 of that year determines the discharge rate.

Days of care—The total number of patient days accumulated at time of discharge by patients discharged from shortstay hospitals during a year constitute days of care. A stay of

less than 1 day (patient admission and discharge on the same

day) is counted as 1 day in the summation of total days of care.

For patients admitted and discharged on different dnys, the

number of days of care is computed by counting all days from

(and including) the date of admission to (but not including) the

date of discharge,

Rate of da.vs qf care—The rate of days of care is the ratio

of the number of patient days accumulated at time of discharge

by patients discharged from short-stay hospitals during a year

to the number of persons in the civilian population on July 1 of

that year.

Average length of stay—The average length of stay is the

total number of patient days accumulated at time of discharge

by patients discharged during the year divided by the number

of patients discharged.

Diagnoses

Discharge diagnoses—One or more diseases or injuries

(or some factor that influences health status and contiact with

health services that is not itself a current illness or injury) listed

by the attending physician on the medical record of patients. In

the NHDS all discharge (or final) diagnoses listed on the face

sheet (summary sheet) of the medical record for patients discharged from the inpatient service of short-stay hospitals are

transcribed in the order listed. Each sample discharge is

assigned a maximum of seven 5-digit codes according to

ICD–9–CM. The number of principal or first-listed diagnoses

is equivalent to the number of dkcharges.

Principal diagnosis—The condition established after study

to be chiefly responsible for occasioning the admission of the

patient to the hospital for care is called the principal diagnosis.

First-listed diagnosis—The coded diagnosis identified as

the principal diagnosis or listed first on the face sheet of the

medical record is the first-listed diagnosis. The number of firstlisted diagnoses is equivalent to the number of discharges.

All-listed diagnoses—All-listed diagnoses are an estimated

number of dkcharge (or final) diagnoses, up to a maximum of

seven, that are listed on the face sheet of the medical r,ecord for

inpatients discharged from non-Federal short-stay hospitals

during the year.

Obstetrical diagnosis—A diagnosis relating to conditions

arising from or affecting the management of pregnancy, childbirth, and the pue~erium (the period following childbirth).

These are code numbers 640–676 of the International Classi58
jlcation of Diseases, 9th Revision, Clinical Mod@cation

(ICD-9-CM),2

Normal deJive~—Delivery without abnormality or complication of pregnancy, childbirth, or the puerperium, and with

spontaneous cephalic dclive~ (that is, presentation of the child

heatilrst and delivery of the child without external aid), No

mention of fetal manipulation or instrumentation is made.

ICD-9-CM code 650 is assigned,

Complicated deliveq.v-All deliveries not considered

normal, including deliveries of multiple gestation, ICD-9-CM

code numbers 640-648 and 651-676 are assigned.

Surgical and nonsurgical procedures

Discharges with procedures—The estimated number of

patients discharged from non-Federal short-stay hospitals during the year who underwent at least one procedure during their

hospitalization are termed “dischruges with procedures.”

Procedure—Aprocedure is one or more surgical or nonsurgical operations, diagnostic procedures, or special treatments

assigned by the physician to the medical record of patients

discharged from the inpatient service of short-stay hospitals, In

the NHDS all terms listed on the face sheet of the medical

record under captions such as “operation,” “operative procedures,“ “operations ancl/orspecialtreatments” are transcribed

in the order listed. A maximum of four 4-digit codes are assigned per sample discharge according to ICD-9-CM and

NHDS directives, (See “Medical coding and edit” in the “Data

collection and processing” section of appendix I for further

details.)

A1l-listedproceduns—All ceded procedures that are listed

on the face sheet of the medical record exclusive of most Class

4 procedures,

U.DDS classesofpmcedures—Proceduresarecategorized

into four classes according to UHDDS guidelines, Classes

1-3 consist of significant procedures—that is, procedures that

carry an operative or anesthetic risk or require highly trained

personnel, special facilities, or special equipment, Class 4

procedures do not meet these criteria,

UHDDS Class 1 procedures—All procedures not categorized as Class 2,3, or 4 procedures,

UHDDS Class2 procedures-The following ICD-9-CM

procedure codes identifi Class 2 procedures as categorized by

the UHDDS:
