Cost and Utilization

American Hospital Association Annual Survey of Hospitals

Conducted annually by the AHA since 1946, the AHA Annual Survey of Hospitals is one of the most comprehensive sources for individual hospital data available. Hospitals report data for a complete fiscal year. Contains data items on organizational structure, facilities, services, community orientation, utilization, financing, and personnel.

Area Resource File (ARF)

Produced annually, the ARF is a county-level compilation of existing data from numerous sources including the American Hospital Association, the American Medical Association, the U. S. Census Bureau, the National Center for Health Statistics, and the Health Care Financing Administration. The ARF is cumulative, with the completeness and frequency of data elements varying by source. The ARF contains data items on health professions, health professions training, health facilities, hospitalization utilization, hospital expenditures, population characteristics and economic data, and environment. Also available are geographic descriptors--such as Federal Information Processing Standards (FIPS) codes and Metropolitan Area (MA) codes--that allow for easy aggregation of county data into other geographic groupings.

Dartmouth Atlas of Health Care

For more than 20 years, the Dartmouth Atlas Project has documented glaring variations in how medical resources are distributed and used in the United States. The project uses Medicare data to provide comprehensive information and analysis about national, regional, and local markets, as well as individual hospitals and their affiliated physicians. These reports and the research upon which they are based have helped policymakers, the media, health care analysts and others improve their understanding of the efficiency and effectiveness of our health care system. This valuable data forms the foundation for many of the ongoing efforts to improve health and health systems across America. This web site provides access to all Atlas reports and publications, as well as interactive tools to allow visitors to view specific regions and perform their own comparisons and analyses.

Health Cost and Utilization Project (H-CUP)

The Healthcare Cost and Utilization Project (HCUP, pronounced "H-Cup") is a family of health care databases and related software tools and products developed through a Federal-State-Industry 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 patient-level health care data (HCUP Partners). HCUP includes the largest collection of longitudinal hospital care data in the United States, with all-payer, encounter-level 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: 1) Create and enhance a powerful source of national, state, and all-payer health care data, 2) Produce a broad set of software tools and products to facilitate the use of HCUP and other administrative data, 3) Enrich a collaborative partnership with statewide data organizations aimed at increasing the quality and use of health care data, and 4) Conduct and translate research to inform decision making and improve health care delivery. Please see the Nationwide Inpatient Sample , the Kid’s Inpatient Database , and the Nationwide Emergency Department Sample descriptions for more detail. Participating state-specific data is also available.

Health, United States

Health, United States presents national trends in health statistics on such topics as birth and death rates, infant mortality, life expectancy, morbidity and health status, risk factors, use of ambulatory and inpatient care, health personnel and facilities, financing of health care, health insurance and managed care, and other health topics.

Kids' Inpatient Database (KID)

The Kids' Inpatient Database is one database in the ARHQ's Healthcare Cost and Utilization Project (HCUP) family of databases. The KID contains hospital stay information for children 20 years of age and younger (18 and younger for 1997). Data are taken from a sample of pediatric discharges from 3,500+ hospitals in selected states. The 2006 KID includes data from Arizona, Arkansas, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Iowa, Illinois, Indiana, Kansas, Kentucky, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, Nevada, New Jersey, New Hampshire, New York, North Carolina, Ohio, Oklahoma, Oregon, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, and Wisconsin. Data items in the KID include demographics, diagnoses, procedures, admission and discharge status, and payer information. For some states, the KID can be linked to hospital-level data from the American Hospital Association's Annual Survey of Hospitals.

Medical Expenditure Panel Survey (MEPS)

The Medical Expenditure Panel Survey, which began in 1996, is a set of large-scale surveys of families and individuals, their medical providers (doctors, hospitals, pharmacies, etc.), and employers across the United States. MEPS collects data on the specific health services that Americans use, how frequently they use them, the cost of these services, and how they are paid for, as well as data on the cost, scope, and breadth of health insurance held by and available to U.S. workers.

Medicare Healthcare Cost Report Information System (HCRIS)

Medicare-certified institutional providers are required to submit an annual cost report to a Medicare Administrative Contractor (MAC). The cost report contains provider information such as facility characteristics, utilization data, cost and charges by cost center (in total and for Medicare), Medicare settlement data, and financial statement data. CMS maintains the cost report data in the Healthcare Provider Cost Reporting Information System (HCRIS). HCRIS includes subsystems for the Hospital Cost Report (CMS-2552-96 and CMS-2552-10), Skilled Nursing Facility Cost Report (CMS-2540-96), Home Health Agency Cost Report (CMS-1728-94), Renal Facility Cost Report (CMS-265-94), Health Clinic Cost Report (CMS-222-92) and Hospice Cost Report (CMS-1984-99).

Nationwide Inpatient Sample (NIS)

The NIS is one database in the ARHQ's Healthcare Cost and Utilization Project (HCUP-3) family of databases. The NIS database contains hospital inpatient stay information taken from 100% of discharges from sampled hospitals in selected states. This design is intended to approximate a 20% sample of U.S. hospitals. Between 700 and 1,000 hospitals per year are included, drawn from between 8 and 38 states. The most recent release of the NIS includes data from Arizona, Arkansas, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Illinois, Indiana, Iowa, Kansas, Kentucky, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, Nevada, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, Oregon, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, Vermont, Washington, West Virginia, and Wisconsin. Data items in the NIS include demographics, diagnoses, procedures, admission and discharge dates and status, and payer information. The NIS can be linked to hospital-level data from the American Hospital Association's Annual Survey of Hospitals and county-level data from the Bureau of Health Professions' Area Resource File.

Organization for Economic Cooperation and Development (OECD) Health Data

OECD Health Data provides internationally comparable data on the health care systems of OECD's 30 member countries. It includes historic data, with some time series available back to 1960, and contains information on life expectancy, potential life years lost, premature mortality, perceived health status, medical facilities, health employment, trade in health goods and services, expenditures, environment, nutrition, discharge rate, length of stay, surgical procedures, demographics, education, and economy.
