Overview of HCUP

The HCUP (pronounced "H­CUP") family of health care databases

and related software tools and products is made possible by a

Federal­State­Industry partnership sponsored by the Agency for

Healthcare Research and Quality (AHRQ).

HCUP

The Healthcare Cost and

Utilization Project (HCUP,

pronounced "H­Cup") is a family

of health care databases and

related software tools and

products developed through a

Federal­State­Industry

partnership and sponsored by

the Agency for Healthcare

Research and Quality (AHRQ).

HCUP databases bring together

the data collection efforts of

State data organizations,

hospital associations, private

data organizations, and the

Federal government to create a

national information resource of

encounter­level health care

data (HCUP Partners). HCUP

includes the largest collection

of longitudinal hospital care

data in the United States, with

all­payer, encounter­level

information beginning in 1988.

These databases enable

research on a broad range of

health policy issues, including

cost and quality of health

services, medical practice

patterns, access to health care

programs, and outcomes of

treatments at the national,

State, and local market levels.

HCUP's objectives are to:

Create and enhance a

powerful source of

national, state, and allpayer health care data.

Produce a broad set of

HCUP Databases

The HCUP Databases provide

data beginning in 1988 and

contain encounter­level

information for all payers

compiled in a uniform format

with privacy protections in

place.

HCUP databases include:

The National (Nationwide)

Inpatient Sample (NIS)

containing data on more than

seven million hospital stays

each year.

The Kids' Inpatient Database

(KID) is a nationwide sample

of pediatric inpatient

discharges.

The Nationwide Emergency

Department Sample (NEDS)

is a database that yields

national estimates of

emergency department (ED)

visits.

The Nationwide

Readmissions Database

(NRD) is a unique and powerful

database designed to support

various types of analyses of

national readmission rates for

all payers and the uninsured.

The State Inpatient

Databases (SID) contain the

universe of inpatient discharge

abstracts from participating

states.

HCUP Tools and Software

The HCUP databases have been

a powerful resource for the

development of tools that can

be applied to other similar

databases by health services

researchers and decision

makers.

HCUPnet is a free, on­line query

system based on data from the

Healthcare Cost and Utilization

Project (HCUP). It provides

access to health statistics and

information on hospital

inpatient and emergency

department utilization.

The AHRQ Quality Indicators

(QIs) are measures of health

care quality that make use of

readily available hospital

inpatient administrative data.

The AHRQ QIs consist of three

modules measuring various

aspects of quality. Software and

user guides for all three

modules are available to assist

users in applying the Quality

Indicators to their own data.

The Clinical Classifications

Software (CCS), was developed

with HCUP data and is available

for downloading. The CCS

provides a method for

classifying diagnoses or

procedures into clinically

meaningful categories, which

can be used for aggregate

statistical reporting of a variety

of types.

What is HCUP ?

HCUPnet definitions

A brief description of HCUPnet definitions. HCUP Home

HCUPnet definitions

Below is a list of terms used in HCUPnet and their definitions.

Admission from long term care facility indicates the patient was admitted from a long term

facility such as a nursing home. Not available for 2007 and after.

Admission from another hospital indicates the patient was admitted to this hospital from another

short term, acute­care hospital. This usually signifies that the patient required the transfer in order

to obtain more specialized services that the originating hospital could not provide. Not available for

2007 and after.

Age group in years, calculated on the basis of the admission date to the hospital.

Aggregate charges or the "national bill" is the sum of all charges for all hospital stays in the U.S.

When a case was missing information on charges, a value was imputed by taking the mean charges

for all discharges of the same DRG with non­missing charges. Fewer than 2% of cases are missing

charges in HCUP data. Because of how missing charges are imputed, simple calculation of number

of discharges X mean charge will not always equal the aggregate charges shown in HCUPnet.

For the calculation of charges, if length of stay was over 365 days or total charges were over $5

million, the record was dropped from the NIS and if length of stay was missing, total charges were

set to missing and imputed as specified above.

Aggregate costs are the sum of all costs for all hospital stays. See Costs and Aggregate

charges for details.

All­listed diagnoses include the principal diagnosis plus additional conditions that coexist at the

time of admission, or that develop during the stay, and which have an effect on the treatment or

length of stay in the hospital.

The unit of analysis remains the discharge: if a particular procedure or diagnosis occurs multiple

times during the same discharge, it is still counted only once.

All­listed procedures include all procedures performed during the hospital stay.

The unit of analysis remains the discharge: if a particular procedure or diagnosis occurs multiple

times during the same discharge, it is still counted only once.

All Stays. All patients in general, not specific diagnoses or procedures.

Ambulatory surgeries were selected based on the type of procedures performed. All statistics are

limited to invasive surgery commonly performed for therapeutic purposes (i.e., to treat disease or

injury). Excluded were noninvasive surgeries and procedures typically used for diagnostic or

exploratory purposes (e.g., colonoscopy). The HCUP Surgery Flag software was used to identify

invasive, therapeutic surgeries based on a narrow, targeted, and restrictive definition that includes

surgical procedures involving incision, excision, manipulation, or suturing of tissue that penetrates

or breaks the skin; typically require use of an operating room; and also require regional anesthesia,

general anesthesia, or sedation to control pain. If a procedure appears more than once on the

record, it is de­duplicated, i.e., counted only once.

Associated principal diagnoses refer to principal diagnoses that appear with the procedure you

have chosen, for example, "For what conditions do patients receive total hip replacement?"

Associated principal procedures refer to principal procedures that appear with the diagnosis you

have chosen, for example, "What principal procedures are received by patients with acute

myocardial infarction?"

Bedsize indicates the size of the hospital in terms of how many short­term, acute care beds are in

the hospital.

Bedsize categories (1993­1997) Bedsize categories (1998 and after)

Clinical Classifications Software (CCS) categorizes patient diagnoses and procedures into a

manageable number of clinically meaningful categories. Instead of wading through the 12,000

diagnosis codes and 3,500 procedure codes from the International Classification of Diseases, 9th

Revision, Clinical Modification (ICD­9­CM), CCS groups them into about 260 diagnosis categories

and 230 procedure categories. This "clinical grouper" makes it easier to quickly understand patterns

of diagnoses and procedures. Each hospital stay can have multiple diagnoses and multiple

procedures. CCS was developed at the Agency for Healthcare Research and Quality (AHRQ).

In all paths except "National Statistics on Mental Health Hospitalizations:" Beginning with 2007, the

CCS categories for mental health and substance abuse were replaced with the Clinical Classification

Software for Mental Health Substance Abuse (CCS­MHSA). As a result, the original CCS mental

health categories of 65­75 were replaced with the mental health categories from the CCS­MHSA

which are numbered 650­663 and 670. In addition to new categories, there were changes in the

assignment of ICD codes to these CCS categories. Maternal ICD codes for mental health and

substance abuse were originally included in CCS categories for pregnancy complications; however,

with the revised CCS, these ICD codes have been placed into mental health and substance

categories. Similarly, E codes for suicide and self­inflicted injury were originally placed into the E

code categories at the end of the CCS based on the mechanism of injury. With the revised CCS,

suicide and self­inflicted injury E codes are grouped into a separate category in the mental health

series of CCS categories. Finally, the original CCS category of 150 Alcohol­related liver disease has

been dropped and the codes have been placed into the alchohol abuse CCS category of 660.

For "National Statistics on Mental Health Hospitalizations" the CCS­MHSA is used for all years.

Children's hospitals are defined based on information from the AHA Annual Survey of Hospitals as

well as the Children's Hospital Association (CHA), formerly known as the National Association of

Children's Hospitals and Related Institutions (NACHRI).

The designation of "Free­standing children's hospitals" is based on the AHA Annual Survey. This is

the narrowest definition of a children's hospital and excludes "children's hospitals within hospitals."

The designation of "Children's hospitals, including children's units within other hospitals" is based

on data from the Children's Hospital Association and comprises a broad definition of children's
hospitals (data element = NACHTYPE in the 1997­2009 Kids' Inpatient Database (KID); no longer

available in the 2012 KID). Both definitions are provided here to provide continuity in statistics

over the years presented in HCUPnet.

Costs tend to reflect the actual costs of production, while charges represent what the hospital

billed for the case. Total charges were converted to costs using cost­to­charge ratios based on

hospital accounting reports from the Centers for Medicare and Medicaid Services (CMS). In general,

costs are less than charges. For each hospital, a hospital­wide cost­to­charge ratio is used because

detailed charges are not available across all HCUP States.

In general, costs for cases with a high proportion of ancillary charges (e.g., major surgery) will tend

to be overestimated using these cost­to­charge ratios while costs for cases with a high proportion

of room and board charges (e.g., tracheostomy, mental illness, premature newborns) will tend to be

underestimated.

More detail on the validity of using cost­to­charge ratios to estimate costs:

In general, it was not possible to estimate costs for each inpatient stay based on the use of specific

services or departments. However, in ten HCUP States reporting detailed charges for each discharge

in 2006, the cost for cases in each CCS diagnostic category and in each APR­DRG category was

calculated using department­level cost to charge ratios (CCRs) from the CMS accounting system.

Such cost estimates are more accurate than the cost estimation methods reported in HCUPnet.

However, less than one­third of cases had a cost that differed from using hospital­wide CCRs by

10%. Most categories needing an upward adjustment of cost were in labor and delivery, newborns,

nervous system, cerebrovascular accident, and mental health problems. Categories needing a

downward adjustment in estimated cost were in surgical procedure cases such as cardiovascular

surgery and hip or knee replacement. For details on these tests and data that can be used to adjust

cost for more accuracy, see the HCUP Methods Series, report 2008 #4 (126 KB; PDF Help). The

peer­grouping method to impute a cost­to­charge ratio, when credible hospital­specific information

was not available for a particular hospital from CMS, has been described and tested and is checked

annually.

In 2004, mean and aggregate costs for the Northeast region are slightly overestimated relative to

other regions and years because of a change in the sampling strategy (specifically, hospitals from

Pennsylvania were no longer available for sampling in 2004). However, estimates are reliable when

comparing groups of cases across hospital types, patient characteristics, or diagnosis and procedure

clusters. More details are available upon request by contacting hcup@ahrq.hhs.gov.

For the calculation of costs, hospital­specific cost­to­charge ratios as described above were used.

When a cost­to­charge ratio was missing for a hospital, the average ratio for the hospital's stratum

(as defined by bedsize, teaching status, location, owenership, and region) was used. See also the

definition of charges for information on how charges were computed.

Users calculating costs based directly on HCUP data with the public use version of the cost­tocharge ratio (CCR) file will notice slight discrepancies between the cost values in HCUPnet and

those produced using raw HCUP data and the CCR file. The reason for this difference is that the

public use version of the CCR file masks identities of some hospitals by using a mean CCR, while

HCUPnet uses actual CCRs for all hospitals.

Died generally indicates in­hospital mortality. Some unknown number of cases may have died

outside the hospital, but still be included in HCUPnet.

Discharge. The unit of analysis for HCUP data is the hospital discharge (i.e., the hospital stay),

not a person or patient. This means that a person who is admitted to the hospital multiple times in

one year will be counted each time as a separate "discharge" from the hospital.
Discharge status indicates the disposition of the patient at discharge from the hospital, e.g.,

routine (home), to another short term hospital, to a nursing home, to home health care, or against

medical advice (AMA).

Diagnosis. Specific condition or disease affecting hospitalized patients.

Diagnosis Related Groups (DRGs) comprise a patient classification system that categorizes

patients into groups that are clinically coherent and homogeneous with respect to resource use.

DRGs group patients according to diagnosis, type of treatment (procedures), age, and other

relevant criteria. Each hospital stay has one DRG and one MDC assigned to it.

The Prospective Payment System (PPS) uses approximately 500 DRGs as the basis for payment to

hospitals. Under this system, hospitals are paid a set fee for treating patients in a single DRG

category, regardless of the actual cost of care for the individual. "CC" in the DRG labels refers to

"complications and comorbidities."

DRGs change annually; a new version is implemented each October 1. As a result, DRG information

for the last quarter of each year differs from the DRGs in the first three quarters, but in most years

this is an incremental change. With the introduction of DRG version 25 in October 2007, the DRG

system underwent a major change with the addition and redefinition of numerous DRGs. In order to

avoid this shift in DRG information in HCUPnet for 2007 data, DRG version 24 was retained

throughout calendar year 2007 and DRG version 25 will be applied beginning with calendar year

2008 data.

Beginning in the 4th quarter of 2008, DRGs require that certain conditions ("healthcare associated

conditions" or HACs) have accompanying documentation on whether the conditions were present on

admission (POA) or whether they originated during the stay. When POA information for these HACs

is missing, cases were assigned to a DRG and MDC indicating the cases were "ungroupable," thus

information on the specific condition or body system is lost. Because DRG and MDC information is

used in HCUPnet to provide insight into what conditions are being treated in hospitals, NIS data on

DRGs and MDCs were created without consideration of whether POA information was available

beginning with 2009 data; however, SID data are presented using the original DRG and MDC which

requires POA information.

Dually eligible includes patients who are covered by both Medicare and Medicaid

Emergency admission indicates the patient was admitted to the hospital through the emergency

department. Not available for 2007 and after.

Hospital charges is the amount the hospital charged for the entire hospital stay. It does not

include professional (MD) fees. If you asked for information about procedures, charges will reflect

the total hospital charge, not the charge for that procedure. Charges are not necessarily how much

was reimbursed.

You can choose mean or median charges. Mean is the average. Median is the midpoint ­ half of the

cases fall below this value and half are above this value. The median is provided because the mean

can be strongly influenced by extreme values.

ICD­9­CM stands for the "International Classification of Diseases ­ 9th revision ­ Clinical

Modification." All diagnoses (or conditions) and all procedures that patients receive in the hospital

are assigned an ICD­9­CM code. Codes for diagnoses can be up to 5 digits long and codes for

procedures can be up to 4 digits long. There are about 12,000 diagnosis codes and about 3,500

procedure codes. Each hospital stay can have multiple diagnoses and multiple procedures.

In­hospital deaths indicates in­hospital mortality.
Inpatient Quality Indicators (IQIs) are a set of measures that reflect quality of care inside

hospitals. These indicators use hospital administrative data and include:

(1) Inpatient mortality for certain procedures and medical conditions;

(2) Utilization of procedures for which there are questions of overuse, underuse, and misuse.

The IQIs were developed after comprehensive literature review, analysis of ICD­9­CM codes,

implementation of risk adjustment, and empirical analysis.

Location indicates whether the hospital is in a metropolitan area ("urban") or non­metropolitan

area ("rural"), as defined by American Hospital Association (AHA) Annual Survey, using the 1993

U.S. Office of Management and Budget definition.

Length of stay is the number of nights the patient remained in the hospital for this stay. A patient

admitted and discharged on the same day has a length of stay = 0.

You can choose the mean or median. Mean is the average. Median is the midpoint ­ half of the

cases fall below this value and half are above this value. The median is provided because the mean

can be strongly influenced by extreme values.

Major Diagnosis Categories (MDCs) are broad groups of DRGs (Diagnosis Related Groups) that

relate to an organ or a system (digestive system, for example) and not to an etiology. For

example, MDC 01 ­ Diseases and Disorders of the Nervous System, MDC 02 ­ Diseases and

Disorders of the Eye, MDC 03 ­ Diseases and Disorders of the Ear, Nose, Mouth and Throat. Each

hospital stay has one DRG and one MDC assigned to it.

Beginning in the 4th quarter of 2008, DRGs require that certain conditions ("healthcare associated

conditions" or HACs) have accompanying documentation on whether the conditions were present on

admission (POA) or whether they originated during the stay. When POA information for these HACs

is missing, cases were assigned to a DRG and MDC indicating the cases were "ungroupable," thus

information on the specific condition or body system is lost. Because DRG and MDC information is

used in HCUPnet to provide insight into what conditions are being treated in hospitals, NIS data on

DRGs and MDCs were created without consideration of whether POA information was available

beginning with 2009 data; however, SID data are presented using the original DRG and MDC which

requires POA information.

National bill. The national bill, or aggregate charges, is the sum of all charges for all hospital

stays in the U.S. When charge information was missing for a particular hospital stay, HCUPnet

assigns the average charge for all hospital stays in the same Diagnosis Related Group (DRG) with

non­missing charges. Fewer than 2% of cases are missing charges in HCUP data. Because of how

missing charges are imputed, simple calculation of number of discharges X mean charge will not

always equal the aggregate charges shown in HCUPnet.

Neonatal discharges are identified using the Major Diagnostic Category (MDC) 15 Newborns and

Other Neonates with Conditions Originating in the Perinatal Period.

Maternal discharges are identified using the Major Diagnostic Category (MDC) 14 Pregnancy,

Childbirth and the Puerperium.

Both MDCs were assigned without using "present on admission" information on the record because

not all HCUP data sources provide present on admission indicators which prevents assignment of

the standard MDC for records involving Hospital Acquired Conditions (HAC).

Ownership/control was obtained from the American Hospital Association (AHA) Annual Survey of

Hospitals and includes categories for government nonfederal (public), private not­for­profit

(voluntary) and private investor­owned (proprietary). These types of hospitals tend to have
different missions and different responses to government regulations and policies.

Location of patient's residence (2003­2006) is based on an urban­rural designation of the

patient's county of residence. The categorization is a simplified adaptation of the 2003 version of

the Urban Influence Codes (UIC), which divide counties into categories based on size and proximity

to population centers. "Large metropolitan" includes metropolitan areas of 1 million people or more.

"Small metropolitan" includes metropolitan areas of at least 50,000 but fewer than 1 million people.

"Non­metropolitan" includes all micropolitan areas (core­based statistical areas of more than

10,000 people but less than 50,000) and all non­urban areas.

Location of patient's residence (beginning with 2007) is based on an urban­rural designation of

the patient's county of residence. The categorization is a simplified adaptation of the 2006 version

of a system developed by the National Center for Health Statistics (NCHS) especially for use in

health care research. The classification emphasizes urban distinctions and is unique in

differentiating between central and fringe counties of large metropolitan areas. Smaller

metropolitan counties are subdivided by population. Non­metropolitan counties are divided simply

into micropolitan and non­core categories. The county classifications are based on the Office of

Management and Budget (OMB) metropolitan/micropolitan assignments as updated through the

2005 revisions (OMB Bulletin No. 06­01). These assignments were refined using information from

the Rural­Urban Continuum Code (RUCC) and Urban Influence Code (UIC) of the Economic Research

Service of the U.S. Department of Agriculture and county characteristics from the 2000 Census and

2004 Census Bureau population estimates. "Large central" refers to counties of metro areas of 1

million or more population, and can be considered cores of large cities. "Large fringe" refers to

counties of metro areas of 1 million or more population and can be considered suburbs of large

cities. "Medium and small metro" refers to counties in metro areas with less than 1 million

population but with at least 50,000. "Micropolitan and noncore" refers to rural counties with less

than 50,000 population.

Payer is the expected payer for the hospital stay.

To make coding uniform across all HCUP data sources, Payer combines detailed categories into

more general groups:

Medicare includes fee­for­service and managed care Medicare patients

Medicaid includes fee­for­service and managed care Medicaid patients.

Private insurance includes Blue Cross, commercial carriers, and private HMOs and PPOs

Uninsured includes an insurance status of "self­pay" and "no charge"

Other includes Worker's Compensation, TRICARE/CHAMPUS, CHAMPVA, Title V, and other

government programs

When more than one payer is listed for a hospital discharge, the first­listed payer is used.

Patients covered by the State Children's Health Insurance Program (SCHIP) may be included under

Medicaid, private insurance or other insurance, depending on the structure of the state program.

Because most state data do not identify SCHIP patients specifically, it is not possible to present

this information separately in HCUPnet.

Pediatric Quality Indicators (PDIs) focus on children and reflect both quality of care inside

hospitals and identify potentially avoidable hospitalizations among children.

Principal diagnosis. The condition established after study to be chiefly responsible for occasioning

the admission of the patient to the hospital for care. The principal diagnosis is always the reason

for admission. (Definition according to the Uniform Bill (UB­92).)

Principal procedure. The procedure that was performed for definitive treatment rather than one

performed for diagnostic or exploratory purposes, or the procedure that was necessary to take care
of a complication. If two procedures appear to meet this definition, then the one most related to the

principal diagnosis should be selected as the principal procedure. (Definition according to Coding

Clinic, fourth quarter 1990, page 5.)

Prevention Quality Indicators (PQIs) are measures that can be used with hospital inpatient

discharge data to identify "ambulatory care sensitive conditions." These are conditions for which

good outpatient care can potentially prevent the need for hospitalization or for which early

intervention can prevent complications or more severe disease.

The PQIs were developed after comprehensive literature review, analysis of ICD­9­CM codes,

implementation of risk adjustment, and empirical analysis.

Patient Safety Indicators (PSIs) are measures that can be used with hospital inpatient discharge

data to identify potentially preventable complications and adverse events. PSIs are a set of

indicators that provide information on potential in­hospital complications and adverse events

following surgeries, procedures, and childbirth.

The PSIs were developed after a comprehensive literature review, analysis of ICD­9­CM codes,

review by a clinician panel, implementation of risk adjustment, and empirical analyses.

Rank Order. Rank diagnoses or procedures by such factors as number of discharges, charges, or

in­hospital mortality rate. For example, you can rank hospital stays in the U.S. from the most

common diagnosis to the least common, or you can rank hospital stays from the most expensive to

the least expensive.

Readmission. A readmission is a subsequent hospital admission in the same or a different

hospital within a certain period of time following an original admission (or index stay).

Readmissions in HCUPnet are 30­day readmissions, thus, the discharge date for the index stay

must occur between January and November to allow a 30­day follow­up period for all index stays.

See "Methods ­ Calculating Readmissions for HCUPnet" PDF (170KB) / HTML.

Readmission rate in HCUPnet is defined as:

the number of stays with at least one subsequent hospital stay within 30 days

the total number of hospital stays between January and November

See "Methods ­ Calculating Readmissions for HCUPnet" PDF (170KB) / HTML.

Region is the four regions defined by the Bureau of the Census: Northeast, Midwest, South, and

West.

Northeast is defined as Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New

York, Pennsylvania, Rhode Island, and Vermont.

Midwest is defined as Illinois, Indiana, Iowa, Kansas, Minnesota, Missouri, Michigan, Nebraska,

North Dakota, Ohio, South Dakota and Wisconsin.

South is defined as Alabama, Arkansas, Delaware, District of Columbia, Florida, Georgia,

Kentucky, Maryland, Mississippi, Louisiana, Tennessee, North Carolina, Oklahoma, South Carolina,

Texas, Virginia, West Virginia.

West is defined as Alaska, Arizona, California, Colorado, Hawaii, Idaho, Montana, Nevada, New

Mexico, Oregon, Utah, Washington, Wyoming.

Not all States participate in HCUP, so not all States will be present in HCUP data. However the

numbers have been extrapolated to represent the entire U.S.

procedure and examine related diagnoses or procedures.

If you choose a specific principal diagnosis, you can then list procedures associated with it, for

example, "What procedures are received by patients with acute myocardial infarction?" Or you can

examine the secondary diagnoses associated with that principal diagnosis. For example, "What

secondary diagnoses are related to acute myocardial infarction?"

If you choose a specific principal procedure, you can then list diagnoses associated with it, for

example, "For what conditions do patients receive total hip replacement?" Or you can look at other

procedures associated with it, for example, "What additional procedures are received by patients

who have a hip replacement?"

Secondary diagnoses refer to additional diagnoses that appear with the principal diagnosis you

have chosen, for example, "What secondary diagnoses are related to acute myocardial infarction?"

Secondary procedures refer to additional procedures that appear with the principal procedure you

have chosen, for example,"What additional procedures are received by patients who have a hip

replacement?"

Trends. Tables and graphs with trends over time.

Teaching status indicates whether the hospital in which the stay occurred is a teaching or a nonteaching hospital. A hospital is considered to be a teaching hospital if the American Hospital

Association (AHA) Annual Survey indicates it has an AMA­approved residency program, is a

member of the Council of Teaching Hospitals (COTH), or has a ratio of full­time equivalent interns

and residents to beds of .25 or higher.

† Aggregate costs or charges for community hospital stays where this was the principal diagnosis, in U.S. dollars (2013)

Weighted national estimates from HCUP National Inpatient Sample (NIS), 2013, Agency for Healthcare Research and Quality (AHRQ), based on data collected by individual States and provided to AHRQ by the States. Total number

of weighted discharges in the U.S. based on HCUP NIS = 35,597,792. Statistics based on estimates with a relative standard error (standard error / weighted estimate) greater than 0.30 or with standard error = 0 in the nationwide

statistics (NIS, NEDS, and KID) are not reliable. These statistics are suppressed and are designated with an asterisk (*). The estimates of standard errors in HCUPnet were calculated using SUDAAN software. These estimates may

differ slightly if other software packages are used to calculate variances.

Beginning with the 2012 data, the National Inpatient Sample (NIS) was redesigned to optimize national estimates. The nationwide statistics in HCUPnet for years prior to 2012 were regenerated using new trend weights in order to permit longitudinal analysis. The regenerated data were posted to HCUPnet on 7/2/2014. The statistics for years prior to

2012 currently on HCUPnet will differ slightly from statistics obtained prior to 7/2/2014. For more information about the NIS redesign and trend weights, please view the

Overview of the NIS .
