Utilization of

Short-Stay

Hospitals:

United States, 1981

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.

Utilization of Short-Stay

Hospitals

Annual Summary

by Edmund J. Graves and Barbara J. Haupt,

Division of Health Care Statistics

Introduction

This report provides national estimates on the utilization

of non-Federal shoti-stay hospitals during 1981. Data are

summarized for selected demographic characteristics of the

patients discharged, characteristics of the hospitals where the

patients were treated, conditions diagnosed, and surgical and

nonsurgical procedures performed.

The statistics in t.hk report are based on data collected by

the National Center for Health Statistics by means of the National Hospital Discharge Survey, 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

short-stay general and specialty hospitals located in the United

States. Approximately 227,000 medical records from 550

hospitals were included in the 1981 survey. A brief descrip

tion of the sample design and the sources of data can be found

in appendix I. A detailed report on the design of the National

Hospital Discharge Survey was published in 1970.1

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 and by

the geographic region, bed size, and ownership of the shortstay hospitals (tables 1– 12). Statistics on the conditions

diagnosed (tables 13– 17) and procedures performed (tables

18-22) are also shown by patient and hospital characteristics.

Data for newborn infants are included only in the section

“Newborn infant discharges.” Since 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 Class&cation of Diseases, 9#z Revision, Clinical i140dz@ztion2 (ICD–9–CM).

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

Revision International Classzzcation 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 are 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 National Hospital Discharge Survey, these

diagnoses are excluded from this report. The conditions diagnosed and procedures performed are presented here by the

major diagnostic classes and procedure groups of the ICD–9–

CM. Within these classes and groups, some categories of diagnoses and procedures are also shown. These spec~lc categories

were selected primarily because of large fi-equencies 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 National

Hospital Discharge Survey is important for interpreting the

data and for making comparisons with statistical data on shortstay hospital utilization that are available from other sources.

Definitions of the terms used in this report are presented in

appendix II.

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

Statistics, the National Health Interview Survey. Estimates

from this survey are generally different from those of the National Hospital Discharge Survey (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.
Highlights

During 1981 an estimated 38.5 million inpatients, excluding newborn infants, were discharged from non-Federal shortstay hospitals. These patients used 277.2 million days of care

during the year. Their average length of stay was 7.2 days.

Approximately 42 percent of the patients were discharged

within 4 days of their admission and 6-percent remained in

the hospital for 3 weeks or longer. Patients hospitalized during 1981 accounted for 169 discharges and 1,218 days of care

per 1,000 civilian population.

Prior to 1981, the rates were based on the civilian noninstitutionalized population. Starting in 1981, however, the

rates were based on the civilian population. Because the civilian

population is larger than the civilian noninstitutionalized population, rates based on the former will be slightly lower than

those based on the latter. The change in the type of population

used in computing rates was necessary because many institutionalized people use shoti-stay hospitals. This is especially

true for persons in the older age groups because these patients

are often admitted from nursing homes.

Selected measures of hospital utilization for 1965, 1970,

1975, 1980, and 1981 are as shown in table A. The number

of discharges was approximately 33 percent higher in 1981

than in 1965; however, the discharge rate was only 12 percent

higher for the same period. Smaller increases were noted for

days of care. Although the number of days of care was 23

percent higher the rate differences were not statistically

significant.

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 I.

The percent of patients with surgery was higher in 1980

and 1981 than in 1965–75. This was due primarily to the inclusion of nonsurgical procedures and some obstetrical pr~

cedures that were not included before 1978.

Utilization by patient characteristics

The 38.5 million patients discharged from short-stay

hospitals during 1981 included an estimated 15.4 million males

and 23.2 million females (table 1). The rates per 1,000 POP

ulation were 140 for males and 197 for females, making the

rate for females almost 41 percent higher than the rate for

males. The number and rate of discharges are always higher

for females than for males because of the large number of

women in their childbearing years ( 15–44 years of age) who

are hospitalized for deliveries and other obstetrical conditions. Excluding deliveries, the rate for females discharged

was 164, or only about 17 percent higher than the rate for

males (table 8).

Except for children under 5 years of age and women in

their childbearing years, 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 5

times higher for both sexes.

In 1981, male patients used an estimated 117.8 million

days of care in short-stay hospitals, compared with 159.4 million days of care used by females (table 2). The rate of days

of care per 1,000 population was 1,072 for males and 1,354

for females, or about 26 percent higher for females than 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 for about 3.9 million women who were hospitalized for deliveries was only 3.7 days. This length of stay

compares with an average length of stay of 7.7 days for males

and 7.5 days for females who were not hospitalized for deliveries (tables 2 and 6).

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

increased about 12 times with advancing age from 337 for patients under 15 years of age to 4,155 for patients 65 years of

age and over (table 2). 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 years of age and over (10.5 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.

The proportion of males (49 percent) and of females (52

percent) who were discharged from shoti-stay hospitals within

4 days of their admission were approximately equal (table 3).

The percent of patients hospitalized fewer than 5 days decreased with each older age group from 74 percent for those

under 15 years of age to 30 percent for patients 65 years of

age and over. Conversely, the proportion of patients hospitalized for 3 weeks or longer increased from about 3 percent for

the youngest age group to 11 percent for those 65 years of age

and over. About 7 percent of the males and 5 percent of the

females were hospitalized for at least 3 weeks.

Information on the race of patients is collected through

the NHDS. Prior to 1981, race was reported as “white,” “all

other,” and “race not stated.” In 1981, however, a race was

imputed for those patients whose race was not stated on the

face sheet of the medical record. A brief description of the

methodology used in imputing race is found in the section

“Presentation of estimates” in appendix I. In this repo~ the

race classification used is “white,” “black,” and “all other

races.”

In 1981, an estimated 32.2 million discharged patients

were white, 5.0 million were black, and 1.3 million were all

other races. There were some demographic differences between

the race groups. The largest difference between white, black,

and all other races was in the distribution of discharges by

age. White patients were older than black and all other patients as a group and for both sexes (table 4). Twenty-nine

percent of the white patients were 65 years of age and over,

compared with 15 percent of the black patients and 14 percent

of all other patients. That is, the percent of white patients that

were 65 years of age and over was about twice those of patients classified as black and as all other races. Although the

percents are different, a similar pattern exists in the civilian

population. About 12 percent of the white population, 8 percent

of the black population, and 6 percent of the population classified as all other races are 65 years of age and over.’

aThe estimates are consistent with those published in the U.S. Bureau of the

Census Current Population Reports, Series P-25, Nos. 913 and 917.

The number of days of care in 1981 totaled 231.8 million

for white patients, 37.5 million for black patients, and 7.9 million for all other patients (table 5). The average lengths of stay

were 7.2 days for white patients, 7.5 days for black patients,

and 6.1 days for all other patients (table 6).

Utilization by hospital characteristics

Discharges from short-stay hospitals by geographic region

in 1981 ranged from 6.4 million in the West Region to 13.2

million in the South Region (table 7). 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

1981 were 146 in the West, 159 in the Northeast 174 in the

Sou~ and 190 in the North Central Regions (table 8). Among

the geographic regions, the North Central Region had the

highest discharge rate for patients 45 years of age and over.

For those under 45 years of age, the differences in the discharge rates were not significantly different from those in the

South. However, the number of discharges in the South Region

was about the same or higher for each age and sex group as

compared with the North Central Region, because the population in the South was about a ffi larger than that in the

North Central Region.

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 were primarily

in the North Central and the Northeast Regions (tables 7 and

8). The number of days of care for the total population ranged

from 38.6 million in the West to 90.1 million in the South

Regiom the rate per 1,000 population varied from 884 days in

the West Region to 1,400 days in the North Central Region.

Average lengths of stay by geographic region were 6.0

days in the West, 6.8 days in the South, 7.4 days in the North

Central, and 8.5 days in the Northeast (table 9).

The number of patients discharged from shofi-stay hospitals and days of care by sex and age of the patients and by

geographic region and bed size of the hospitals are as shown

in table 7. The percent distributions of these data are shown

in table B.

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 31 percent for those in the

smallest hospitals to 23 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 d~erences 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

B). However, a smaller percent of days of care than of discharges was recorded for patients aged 15–44 years. For patients 45 years and over a larger percent of days of care than

of discharges was recorded. The differences for those aged

15–44 years were the result of short lengths of stay for females

with deliveries. However, for those over 45 years of age the

differences were the result of the older patients being hospitalized longer than those under 45 years of age.

The average length of stay for patients discharged from

short-stay hospitals in 1981 increased steadily from 5.9 days

in the smallest hospitals (6–99 beds) to 8.1 days in the largest

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

stay was slightly longer for males than for females in all hospitals; however, when females who were hospitalized for deliveries are excluded, the average lengths of stay for both sexes

were virtually the same except for patients under 15 years of

age. The average length of stay increased as the age of the

patients increased regardless of the size of the hospital.

Some exceptions to these patterns in the average length

of stay existed among regions as shown in table :10. For example, the average length of stay did not increase with increasing bed size for female patients 15–44 years of age in the

Northeast Region.

Approximately 7 out of 10 patients in non-Federal short4
stay hospitals were discharged from voluntary nonprofit hospitals operated by church and other nonprofit groups during

every year the NHDS was conducted. In 1981, voluntaxy

nonprofit hospitals provided medical care to an estimated 27.2

million patients, or 71 percent of all patients hospitalized.

Hospitals operated by State and local governments cared for

8.3 million patients, or 22 percent of all discharges, and pr~

prietary hospitals operated for profit cared for 3.0 million patients, or 8 percent of all discharges (table 11).

The estimated 277.2 million days of care utilized by patients in shoti-stay hospitals during 1981 were distributed by

ownership of hospitals in the following manner voluntary

nonprofit, 200.2 million days, or 72 percenc govemmen4 54.6

million days, or 20 Percenc and proprietary, 22.4 million days,

or 8 percent. Average lengths of stay were 7.4 days in voluntary nonprofit hospitals, 6.6 days in government hospitals,

and 7.4 days in proprietary hospitals (table 12).

Utilization by diagnosis

First-listed diagnosis—Diseases of the circulatory system

ranked fust in 1981 among the ICD–9–CM diagnostic classes

as a principal or first-listed diagnosis among patients discharged

from non-Federal short-stay hospitals (table 13). These conditions accounted for an estimated 5.3 million discharges. Other

leading ICD–9–CM diagnostic classes were diseases of the

digestive system (4.7 million discharges~ supplementary classifications, which include females with deliveries (4.6 million

discharges); injury and poisoning (3.6 million discharges);

diseases of the genitourinary system (3.5 million discharges);

and diseases of the respiratory system (3.5 million discharges).

About two-thirds of the patients discharged from non-Federal

short-stay hospitals were included in these six ICD–9–CM

diagnostic classes.

The diagnostic categories presented in this summary report were selected either because they appear as principal or

first-listed diagnoses with great frequency or because the conditions are of special interest. Although many of these categories

such as malignant neoplasm,, heart disease, psychoses, and

fractures all sites are combinations of more detailed diagnoses,

they are presented as single categories without showing the

spec%c diagnostic inclusions.

The number and rate of discharges, days of care, and

average length of stay by selected fret-listed diagnoses in 1981,

including females with deliveries, are presented in table C.

These categories accounted for 48 percent of all patients discharged during 1981 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 and patients in the

smallest hospitals (6–99 beds).

For patients under 15 years of age, the most frequent firstIisted diagnosis was chronic disease of tonsils and adenoids.

Some other frequent diagnoses for these patients were pneumonia, all forms, diseases of the ear and mastoid process, and

noninfectious enteritis and colitis.

Excluding females with deliveries, the two most frequent

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

abortions, including ectopic and molar pregnancies, and fractures, all sites.

The most frequent first-listed diagnosis, besides deliveries,

for patients other than white was heart disease. Other common

diagnoses for this group included malignant neoplasms, all

abortions, including ectopic and molar pregnancies, diabetes

mellitus, and fractures, all sites.

For hospitals with 6–99 beds, the most common firstlisted diagnosis was heart disease, followed by females with

deliveries. Other frequent diagnoses in these hospitals were

pneumonia, all forms, and fractures, all sites.

The number and rate of patients discharged from shortstay hospitals and average length of stay, by ICD–9–CM

diagnostic classes and selected categories, are presented by

age for 1981 in table 13. Although the estimated rates of discharge horn shofi-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 kidney 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 classes

and categories of diagnoses. Overall, it tended to be higher for

mental disorders (especially psychoses), cerebrovascular disease, and malignant neoplasms. Other average lengths of stay

over 10 days were for diseases of the central nervous system

and acute myocardial infarction 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 first-listed 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 and average length of stay for patients

discharged from short-stay hospitals by sex and race are presented by diagnostic classes and selected categories of first

listed diagnosis in table 14. Discharge rates were computed

for sex but not for race. Discharge rates by race, however,

may be computed using population information found in ap

pendix I.

Rates of discharges per 10,000 population were very similar for the two sexes for most of the diagnostic classes 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 hernia, 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, carcinoma in situ, and

neoplasms of uncertain behavior, diabetes mellitus, essential

hypertension, noninfectious enteritis and colitis, cholelithiasis,

arthropathies and related disorders, and persons admitted for

sterilization.

Eighty-four percent of all the patients discharged were

white and 16 percent were all other races (including black);

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 who

were discharged with a first-listed diagnosis of heart disease

(90 percent) and lower for.those with a diagnosis of abortion,

including molar and ectopic pregnancy, and delivery (66 and

77 percent).

Information on patients discharged from shoti-stay hospitals by geographic region are as shown in table 15. In 1981,

the number of discharges per 1,000 population ranged from

146 in the West Region to 190 in the North Central 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.

During 1981, the number of patients discharged from

shoti-stay hospitals and the average length of stay are shown

by bed size of hospital and diagnostic category in table 16.

Females with deliveries ranked as the highest category for firstlisted diagnosis in hospitals of all bed sizes except the smallest.

In hospitals of 6–99 beds, the highest ranking diagnostic

category was that of heart disease.

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 D).

On the other hand, greater proportions of discharges were from

the largest hospitals (500 beds or more) for neopllasms, complications of pregnancy, childbirth and the puerperium, congenital anomalies, certain conditions originating in the perinatal period, and supplemental classifications.

For the most p@ the average length of stay for the diagnostic classes 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 Wes~ 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 (15.5

days) and 200–299 beds (13.6 days).

1Famales with deliveries are included under “Supplementary classifications.’”

were recorded for the 38.5 million inpatients of non-Federal

short-stay hospitals in 1981 (table 17) for an average of 2.4

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 are now

coded and tabulated on the NHDS data file; 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 liveborn twins, both liveborn, 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 2.3–2.5 diagnoses per patient. A larger variation occurred by age. The average number of diagnoses per discharge

for the age groups under 15 years, 15–44 years, 45–64 years,

and 65 yearn and over was 1.7, 2.0, 2.6, and 3.1, respectively.

Diseases of the circulatory system ranked first among the

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

17.4 million diagnoses. This class was followed by diseases of

the digestive system (8.9 million); supplementary classifications (7.8 million); diseases of the genitourinary system (7.7

million); diseases of the respiratory system (6.8 million); and

injury and poisoning (6.5 million). These six ICD–9–CM

classes accounted for almost 60 percent of all-listed diagnoses

in 1981.

Utilization by procedures

One or more procedures were performed for an estimated

20.6 million of the 38.5 million inpatients discharged from

short-stay hospitals during 1981. A total of 33.6 million procedures, or an average of 1.6 per patient who underwent at

least one procedure, were recorded in 1981 (table 18).

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, in

terms of both number per patient and type of procedure, were

coded. Spec~lcally, 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 total number includes many

additional nonsurgical procedures. (See appendix I under the

section entitled “Medical coding and edit” and appendix II

under the section entitled “Terms relating to procedures” for

more information on the diRerences between coding the ICDA

and the ICD–9–CM.)

The number and percent of patients with surgical and nonsurgical procedures in 1981 and the number and percent of

patients with at least one surgical procedure are as shown in

table E. About 53 percent of the patients discharged had some

procedure, including diagnostic and nonsurgical procedures.

Some variations in the proportions, however, occurred by age

and sex of the patien~ geographic region, and bed size of the

hospital. Patients 15–44 years of age had the highest proportion of all the age groups with procedures (63 percent). Women

had more procedures than men (56 percent compared with 49

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 35 percent in hospitals with

6–99 beds to almost 64 percent in hospitals with 500 beds or

more.

Six out of 10 patients (58 percent) with procedures had

only one operation or nonsurgical procedure during their hospitalization (table F). About 26 percent of the patients had

two procedures, about 9 percent had three, and about 6 percent

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

the lowest proportion of multiple procedures (32 percent) and

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

proportion (48 and 49 percent respectively). About 36 percent

of the patients discharged from the smallest hospitals had more

than one procedurq about 40 percent of the patients discharged

from hospitals of all other sizes had two or more procedures

during their hospitalization.

The percent of patients with surgical procedures (i.e., all

procedures except nonsurgical—see appendix II) by number

of procedures are as shown in table F. About tw~thirds (66

percent) of the patients with surgical procedures had only one,

24 percent had two, and 10 percent had three or more.

Procedures are grouped in the detailed tables of this report by the 16 major ICD–9–CM groups. Selected procedures

within 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.

Operations on the digestive system ranked first among the

surgical and nonsurgical procedures (5.6 million) performed

during 1981. These were followed by miscellaneous diagnostic

and therapeutic procedures (4.8 million), operations on the

female genital organs (4.2 million), obstetrical procedures

(3.9 million), and operations on the musculoskeletal system

(3.4 million). Over three-fifths (65 percent) of the procedures

performed in 1981 were included in these five major groups.

The number and rate of all-listed procedures in 1981 by

selected ICD–9–CM categories are shown in table G. 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 have been unpublished by the NHDS prior to 1979 such

as endoscopy on the digestive system, cystoscopy and urethros8

copy, arteriography and angiocardiography using contrast material, and radioisotope scan. Over one-half million of each of

these procedures were performed during 1981.

Data for the more traditional leading surgical operations

are as shown in table G. Some of the most frequently performed surgeries, of which 500,000 or more were performed

in 1981, included diagnostic dilation and curettage of uterus,

excision or destruction of lesion or tissue of skin or subcutaneous tissue, hysterectomy, bilateral destruction or occlusion

of fallopian tubes, cesarean section, and repair of inguinal

hernia.

The estimated 33.6 million procedures performed in 1981

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

categories, by sex and race, and for persons 15 years of age

and over in table 18. The corresponding rates by sex and

for the age group 15 years of age and over are as shown in

table 19.

Of the 33.6 million procedures performed during 1981,

about 12.7 million were for males and 21.0 million were for

females. The corresponding rates per 1,000 population were

148 for both sexes, 115 for males, and 178 for females. Of

the procedures shown in table 18, the most common ones for

males were repair of inguinal hernia and prostatectomy. For

females, the most frequently performed procedures were

diagnostic dilation and curettage of uterus, hysterectomy,

bilateral destruction or occlusion of fallopian tubes, and

cesarean section.

Generally, the percent distribution of total procedures for

white patients was similar to that for all other patients (including black patients). However, all other patients had larger

proportions than white patients for operations on the female

genital organs and obstetrical procedures.

The rate of procedures per 1,000 population increased

with advancing age from 46 for patienta under 15 years to 303

for patients 65 years of age and over (table H). 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 15–44 years of age operated on for obstetrical and gynecological conditions.

gion is presented in table 20 and the corresponding rates are

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

was lowest in the West Region (131) and highest in the North

Central Region (17 1). Rates were highest in all regions for

operations on the digestive system, operations on the female

genital organs, obstetrical procedures, operations on the musculoskeletal system, and miscellaneous diagnostic and therapeutic procedures.

The number of procedures patients underwent in shortstay hospitals during 1981 for each ICD–9–CM category by

bed size of hospital where the procedure was performed are as

shown in table 22. Except for the largest hospitals, operations

on the digestive system were observed to rank highest of alllisted procedures for all hospital bed-size groups and operations on the female genital organs ranked next. The most common procedures for hospitals of 500 beds or more were miscellaneous diagnostic and therapeutic procedures, followed by

operations on the digestive system and operations on the

female genital organs.

Deaths in short-stay hospitals

In 1981, 95.7 percent of patients, excluding new-born infants, who were discharged from short-stay hospitals were

discharged alive, 2.5 percent were discharged dead, and for

1.7 percent a discharge status was not ascribed. Of the estimated 982,000 patients who died, 50.9 percent were male and

49.1 percent were female (table K). As expected, patients 65

years and over accounted for the majority of hospital deaths,

69.4 percent. Patients under 65 years of age accounted for

30.6 percent of the deaths. The 982,000 who were discharged

dead from these hospitals represented about one-half of all

persons who died during 1981.5

The hospital fatality rate is the number of deaths divided

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

conservative rate since the formula assumes that all those patients whose discharge status was not stated were discharged

alive. A fatality rate of 2.5 has been computed for patients in

1981. The rate for males was higher than that for females—

3.3 for males as compared with 2.1 for females.

The 65 years and over age group had a hospital fatality

rate of 6.5; however, patients under 65 years of age had a

fatality rate of 1.1. 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

L. These data are not synonymous with data for underlying

cause of death as reported in Vital Statistics in the Untied

States. Of the estimated 982,000 deaths in short-stay hospitals,

74 percent are accounted for by the diagnostic groupings

shown in table L. Of these, heart disease and malignant neoplasms accounted for about one-half (5 15,000) of all deaths

in shofi-stay hospitals.

For specific diagnoses, the highest fatality rates were for

acute myocardial infarction with a rate of 16.1 per 100 discharges and cardiac dysrhythmias with a rate of 15.9 per

hundred discharges. Other high fatality rates were for nephritis,

nephrotic syndrome and nephrosis with a rate of 13.6 per

hundred discharges, malignant neoplasms (12.6 per hundred

discharges), and congestive heart failure (11.3 per hundred

discharges).

The fatali~ rate for patients 65 years and over was about

6 times as high as that for patients under 65 years of age. The

rates for patients 65 years and over were 7 times as high for

pneumonia, all forms and 4 times as high for chronic ischemic

heart disease.

The average length of stay for patients discharged from

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

table M. The average stay for all patients discharged was 7.2

days. Patients discharged alive had an average stay of 7.0 days,

compared with an average stay of 13.4 days for patients who

died in the hospital.

Patients under 65 years of age, discharged alive, stayed

an average of 5.9 days; however, those who died had an average stay of 13.4 days. The hospital stay for patients 15–44

years of age who died was 2.7 times as long as for those who

were discharged alive (13.6 and 5.1 ). The difference in length

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

10.3 days for those discharged alive and 13.4 days for those

who &led.

Newborn infant discharges

The number, percent distribution, and average length of

stay of newborn infants discharged from short-stay hospitals,

by sex, geographic region, and race are as shown in table N.

The estimated 3.8 million newborn infants were equally divided between the sexes.

Seventy-eight percent (3.0 million) of the 3.8 million

newborn infants were white and 17 percent (0.7 million) were

black. The remaining 5 percent (0.2 million) were of all other

races. The average length of stay for white infants was about

1.1 days less than that for black infants (3.7 days and 4.8 days,

respectively). The average length of stay for infants of ail other

races was 4.1 days.

About 34 percent ( 1.3 million) of newborn discharges were

from the South Region and approximately 27 percent (1.0

million) were from the North Central Region. The percents of

discharges for the West and Northeast were approximately the

same: twenty percent (0.8 million) for the West and 19 percent (0.7 million) for the Northeast. The average length of stay

was longest in the Northeast (4.9 days) and shortest in the

West (3.0 days). The average length of stay was 4.2 days in

the North Central Region and 3.8 days in the South Region.

Approximately three quarters of the 3.8 million newborn infants discharged from short-stay hospitals were “well.” A

“well” infant is defined as one that does not have an illness or

risk-related diagnosis (table O).

The estimated 1.0 million sick infants (27 percent) had at

least one diagnosis in addition to the newborn diagnosis. Some

of these additional diagnoses are as shown in table P. About

0.5 million (31 percent) of the diagnoses were for jaundice.

This was followed by prematurely and respiratory conditions

with 0.2 million (11 percent) each and congenial anomalies

with 0.1 million (9 percent). Males accounted for 59 percent

of the infants with respiratory conditions, 55 percent with

congenital anomalies and prematurity, and 53 percent with

jaundice. Of the 1.0 million sick newborn infants, there were

18 percent more baby boys than baby girls; the boys also had

21 percent more diagnoses than the girls did.

Well newborn infants had an average hospital stay of 3.2

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

(table P). This table further demonstrates that sick newborn

infants stay twice as long as well infimts and account for 41

percent of the newborn patient days, although they compose

only 27 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 from 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 S&e—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

short-stay hospitals contained in the 1963 MFI. This universe

is periodically updated (table I). The distribution of the hospitals in the NHDS universe and sample for 1981 is given by

bed size and geographic regions in table II.

The sample for 1981 consisted of 550 hospitals. Of these,

71 refused to participate, and 51 were out of scope either because the hospital had gone out of business or because it failed

to meet the definition of a short-stay hospital. Thus 428 hospitals participated in the survey during 1981 and provided

approximately 227,000 abstracts of medical records.

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 properly distributed 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 within-hospital sampling ratio for selecting sample

discharges varied inversely with the probability of hospital

selection. The smallest sampling fraction of discharged 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 discharge would be approximately

the same in each size class.

In nearly all hospitals, the daily listing sheet of discharges

was the fkame from which the subsamples of discharges were

selected within the sample hospitals. The sample discharges

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 lcth 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 either by the hospital staff or

by representatives of the National Center for Health Statistics

(NCHS) or by both. In about 52 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 fc~rrecording 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 s$unpleselection control sheets, to a Census

Regional Office. Every shipment of abstracts was reviewed

and each abstract form was checked for completeness. Abstracts were then 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 was

assigned for each sample abstract in addition, if the medical

information included surgical or nonsurgical procedures, a

maximum of four codes for these procedures was 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.

The system currently used for coding the diagnoses and

procedures on NHDS sample patient abstracts is the international Classl#%ation of Diseases, 9th Revision, Clinical

iWodzfication2 (ICD–9–CM). Earlier data for 1970–78 were

coded according to the Eighth Revision international Classification of Diseases, Adapted for Use in the United States3

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

were necessary because of incomplete or ill-defined terminology in the abstracts, are presented elsewhere.7 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 kjunes and surgical and nonsurgical procedures. However, many differences exist between

the two classifications. These differences are discussed in a

previous report.8

The NHDS follows the guidelines of the Uniform Hospital

Discharge Data Set (UHDDS) for coding procedures.9’10 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 inpatient information.

According to UHDDS guidelines, all procedures are allocated into one of four classes. 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 are not

considered significant therefore, reporting of them is optional.

Consequently, with three exceptions, Class 4 procedures are

not coded by the NHDS. The Class 4 procedures that are

‘coded are circumcision (ICD–9–CM code 64.0), episiotomy

(code 73.6), and removal of intrauterine contraceptive device

(code 97.71). See appendix II for the procedure codes included

in these classes.

Presentation of estimates

Grouping of diagnoses and procedures—In this report the

diagnostic classes, 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 service. The diagnostic categories, the most detailed groupings of diseases and injuries

shown, are subsets of the major groups or classes. 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 less than one-fourth

of 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.

Before 1981, if the race of the patient was not identified

on the hospital records, it was recorded as “not stated” for

the NHDS. However, beginning in 1981, a specific race was

imputed for those discharges for which race was not stated on

the medical record face sheet. Race was imputed using both

the distribution of race in the geographic area of the hospital

NOTE: A list of references follows the text.

as reported by the Bureau of the Census and information on

diagnoses and expected source of payment for those records

for which race was reported.

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.

Rounded numbers—Estimates of the numbers of inpatient

discharges, days of care, discharges with procedures, all-listed

diagnoses, and all-listed 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 Repotis, 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 are usually hospitalized in short-stay hospitals. This is especially true for elderly residents of nursing

homes. A report comparing NHDS rates based on the civilian

population with the civilian noninstitutionalized population is

currently being prepared.

Reliability of estimates

Estimation—Statistics produced 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 prwiuce 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.] 1’12

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

under the previous 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

study 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.

56

Detailed accounts of this and other IOM findings have been

published. 13-15

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 percentage of

the estimate.

The standard error of one statistic is generally 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 (e.g., age, sex, race)

and of hospital characteristics (e.g., region, bed size, ownership), and patient characteristics cross-tabulated 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, several curves are shown for a few

variables whose relative standard errors are different. from

those in the curve for “All other variables” that is relevant to

most of the estimates. For example, one curve is applicable

only to estimates of dkcharges 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:

1. Discharges or jirst-listed diagnoses and all-listed diagnoses for patient and hospital characteristics: Relative

standard errors of the estimated number of discharges

and of all-listed diagnoses are obtained from the curves in

figure II.

2. Days of care for discharges or first-listed diagnoses for

patient and hospital characteristics: Relative standard

The presentation of estimates for the NHDS is based on

both the 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 probabilityy 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 design of

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.

3.

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.

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 preceeded by an

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,”

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

no statistically significant difference exists between the estimates being compared. A lack of comment on the difference

between any two estimates does not mean that the difference

was tested and found to be not significant.

Appendix II

Definitions of certain terms

used in this report

Hospitals and hospital characteristics

Hospitals—Short-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 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:

Voluntaty nonproJ7t-Hospitals operated by a church or

another nonprofit organization.

Government—Hospitals operated by State or local governments.

Proprieta~—Hospitals operated by individuals, partnerships, or corporations for profit.

Patient—A person who is formally admitted 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, defined 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 hospital; 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 days,

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 days of care—The rate of days of care is the ratio

of the number of patient days accumulated at time of discharge

by patienta 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.

Terms relating to diagnoses

Discharge diagnoses—One or more diseases or injuries

(or some factor that influences health status and contact 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 shoti-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 discharges.

Princ@al 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 discharge (or final) diagnoses, up to a maximum of

seven, that are listed on the face sheet of the medical record

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, child62
birth, and the puerperium (the period following childbirth).

These are code numbers 640–676 of the International Classification of Diseases, 9th Revision, Clinical J40dzfication

(ICD-9-CM).2

Normal de/ivery-Delivery without abnormality or complication of pregnancy, childbirth, or the puerperium, and with

spontaneous cephalic delivery (that is, presentation of the child

headfhst 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 delive~—All deliveries not considered normal, including deliveries of multiple gestation. ICD–9–CM

code numbers 640–648 and 65 1–676 are assigned.

Terms relating to 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 “discharges with procedures.”

Procedure—A procedure is one or more surgical or nonsurgical operations, procedures, or special treatments assigned

by the physician to the medical record of patients discharged

from the inpatient service of shofi-stay hospitals. In the NHDS

all terms listed on the face sheet (summary sheet) of the medical record under the captions “operation,” “operative procedures,”” operations and/or special treatments,” and the like

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.)

A ii-listed procedures—All coded procedures that are listed

on the face sheet of the medical record exclusive of all but

three Class 4 procedures.

UHDDS classes of procedures—Procedures are categorized 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 are not considered significant; therefore, reporting

is optional.

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

UHDDS Class 2 procedures—The following ICD-9-CM

procedure codes identify Class 2 procedures as categorized
