Adjusted for general inflation
Costs can be adjusted for economy-wide inflation by removing increases that reflect the effect of changing average prices for the same goods and services. In this report, the U.S. Bureau of Economic Analysis Gross Domestic Product Price Index is used to remove economy-wide inflation. Additional inflation that is specific to the hospital sector is not removed in this calculation.
Aggregate costs are the sum of all costs for all hospital stays.
Hospital charges reflect the amount the hospital billed for the entire hospital stay and do not include professional (physician) fees. The charge is generally more than the amount paid to the hospital by payers for the hospitalization and is also generally far more than what it costs hospitals to provide care.
HCUP is based on data from community hospitals, defined as short-term, non-Federal, general and other hospitals, excluding hospital units of other institutions (e.g., prisons). Community hospitals (and HCUP data) include OB-GYN, ENT, orthopedic, cancer, pediatric, public, and academic medical hospitals. They exclude hospitals whose main focus is long-term care, psychiatric, and alcoholism and chemical dependency treatment, although discharges from these types of units that are part of community hospitals are included.
Costs are derived from total hospital charges using cost-to-charge ratios based on hospital accounting reports from the Centers for Medicare and Medicaid Services (CMS). Costs will tend to reflect the actual costs to produce hospital services, while charges represent what the hospital billed for the care. For each hospital, a hospital-wide cost-to-charge ratio is used to transform charges into costs.
Discharge status indicates the disposition of the patient at the time of discharge from the hospital, and includes the following six categories: routine (to home), transfer to another short-term hospital, other transfers (including skilled nursing facility, intermediate care, rehabilitation care, swing bed, and another type of facility such as a nursing home), home healthcare, against medical advice (AMA), or died in the hospital.
In-hospital deaths refer to hospitalizations in which the patient died during his or her hospital stay.
Length of stay
Length of stay is the number of nights the patient remained in the hospital for his or her stay. A patient admitted and discharged on the same day has a length of stay equal to 0.
Maternal female stays
Maternal female stays are hospital stays for females ages 15-44 who are pregnant or gave birth.
Median income is the median household income of the patient's ZIP Code of residence. Median income is a proxy measure of a patient's socioeconomic status.
Metropolitan location indicates that the hospital is in a metropolitan area ("urban") rather than a non-metropolitan area ("rural"), as defined by the American Hospital Association (AHA) Annual Survey, using the 1993 U.S. Office of Management and Budget definition.
Non-maternal female stays
Non-maternal female stays are hospital stays for females of all ages who are not pregnant or did not give birth.
Ownership/control was obtained from the American Hospital Association (AHA) Annual Survey Database and includes categories for government non-Federal (public), private not-for-profit (voluntary), and private investor-owned (proprietary) hospitals. These various types of hospitals tend to have different missions and different responses to government regulations and policies.
Patient age in years, calculated based on the patient's date of birth and admission date to the hospital.
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:
The unit of analysis for HCUP data is the hospital stay (i.e., the hospital discharge), 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.
Stays per population
Stays per population is the hospital stay rate of a particular procedure, diagnosis, or event per number of individuals. This measure indicates the prevalence of hospitalizations, procedures or diagnoses within the population.
