Reference excerpt

The Healthcare Cost and Utilization Project (HCUP, pronounced "H-Cup") is a family of healthcare databases and related software tools and products from the United States that is developed through a Federal-State-Industry partnership and sponsored by the Agency for Healthcare Research and Quality (AHRQ).

General Information HCUP provides access to healthcare databases for research and policy analysis, as well as tools and products to enhance the capabilities of the data. HCUP databases combine the data collection efforts of State data organizations, hospital associations, private data organizations, and the Federal Government to create a national information resource of patient-level healthcare data. State organizations that provide data to HCUP are called Partners. HCUP includes multiyear hospital administrative (inpatient, outpatient, and emergency department) data in the United States, with all-payer, encounter-level information beginning in 1988. These databases enable research on health and policy issues at the national, State, and local levels, including cost and quality of health services, medical practice patterns, access to healthcare, and outcomes of treatments. AHRQ has also developed a set of software tools to be used when evaluating hospital data. These software tools can be used with the HCUP databases and with other administrative databases. HCUP’s Supplemental Files are only for use with HCUP databases. HCUP databases have been used in various studies on a number of topics, such as breast cancer, depression, and multimorbidity, incidence and cost of injuries, role of socioeconomic status in patients leaving against medical advice, multiple chronic conditions and disparities in readmissions, and hospitalization costs for cystic fibrosis.

HCUP User Support Website (HCUP-US) The HCUP User Support website is the main repository of information for HCUP. It is designed to answer HCUP-related questions; provide detailed information on HCUP databases, tools, and products; and offer technical assistance to HCUP users. HCUP’s tools, publications, documentation, news, services, HCUP Fast Stats, and HCUPnet (the online data query system) may all be accessed through HCUP-US. HCUP-US is located at https://www.hcup-us.ahrq.gov.

HCUP Overview Course HCUP has developed an interactive online course that provides an overview of the features, capabilities, and potential uses of HCUP. The course is modular, so users can either move through the entire course or access the resources in which they are most interested. The On-line HCUP Overview Course (https://www.hcup-us.ahrq.gov/overviewcourse.jsp) can work both as an introduction to HCUP data and tools and a refresher for established users.

HCUP Online Tutorial Series The HCUP Online Tutorial Series (https://www.hcup-us.ahrq.gov/tech_assist/tutorials.jsp) is a set of interactive training courses that provide HCUP data users with information about HCUP data and tools, and training on technical methods for conducting research with HCUP data. The online courses are modular, so users can move through an entire course or access the sections in which they are most interested. Topics include loading and checking HCUP data, understanding HCUP’s sampling design, calculating standard errors, producing national estimates, conducting multiyear analysis, and using the Nationwide Readmissions Database (NRD).

HCUP Databases HCUP databases bring together data from State data organizations, hospital associations, private data organizations, and the Federal Government to create an information resource of patient-level healthcare data. HCUP’s databases (https://www.hcup-us.ahrq.gov/databases.jsp) date back to 1988 data files. The databases contain encounter-level information for all payers compiled in a uniform format with privacy protections in place. Researchers and policymakers can use the records to identify, track, and analyze national trends in healthcare use, access, charges, quality, and outcomes. HCUP databases are released approximately 6 to 18 months after the end of a given calendar year, with State databases available earlier than the national or nationwide datasets. Currently, there are eight types of HCUP databases: four with national- and regional-level data and three with State- and local-level data.

National Databases National Inpatient Sample (NIS) (formerly the Nationwide Inpatient Sample): A 20 percent stratified sample of all-payer, inpatient discharges from U.S. community hospitals (excluding rehabilitation and long-term acute-care hospitals). The NIS is available from 1988 forward, and a new database is released annually, approximately 18 months after the end of a calendar year. Kids’ Inpatient Database (KID): A nationwide sample of all-payer pediatric inpatient care discharges. Its large sample size is ideal for developing national and regional estimates and enables analyses of rare conditions, such as congenital anomalies, as well as uncommon treatments, such as organ transplantation. The KID was released every 3 years, from 1997 to 2012 and resumed release again in 2016. Nationwide Emergency Department Sample (NEDS): An all-payer emergency department (ED) database of approximately 30 million records that yields national estimates of 145 million ED visits. The NEDS captures encounters where the patient is admitted for inpatient treatment, as well as those in which the patient is treated and released. The NEDS is released annually and is available from 2006 forward. Nationwide Readmissions Database (NRD): The NRD is designed to support various types of analyses of national readmission rates for all patients, regardless of expected payer for the hospital stay. The NRD is released annually and is available from 2010 forward. Nationwide Ambulatory Surgery Sample (NASS): The NASS is the largest all-payer ambulatory surgery database that has been constructed in the United States, yielding national estimates of major ambulatory surgery encounters performed in hospital-owned facilities. The NASS is released annually and is available starting with the 2016 data year.

Worked examples

Example 1 — a first encounter with Healthcare Cost and Utilization Project

Start with the simplest possible case. Write down what Healthcare Cost and Utilization Project claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Healthcare Cost and Utilization Project before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Healthcare Cost and Utilization Project ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Healthcare Cost and Utilization Project

In research: Healthcare Cost and Utilization Project appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Healthcare Cost and Utilization Project in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Healthcare Cost and Utilization Project is common in secondary-school and first-year university syllabi. It links to neighbouring topics Databases in the United States, Medical databases, United States Department of Health and Human Services, so understanding it makes those chapters shorter.
In everyday life: Look for Healthcare Cost and Utilization Project outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
