The Hospital Inpatient Profiles (HIP) database provides a quick and comprehensive overview of hospital-based activity for over 7,100 diagnoses and procedures. Utilization can be accessed conveniently by disease name, procedure name, or ICD code. The HIP includes total procedures, total discharges, the top six concomitant diagnoses and procedures, average length of stay, age/gender breakouts, discharge status, payment source, and more.
HIP Database Source: The NHDS
The National Hospital Discharge Survey (NHDS), which has been conducted annually since 1965, is a national probability survey designed to meet the need for information on characteristics of inpatients discharged from non-Federal short-stay hospitals in the United States. The NHDS collects data from a sample of approximately 270,000 inpatient records acquired from a national sample of about 500 hospitals. Only hospitals with an average length of stay of fewer than 30 days for all patients, general hospitals, or children’s general hospitals are included in the survey. Federal, military, and Department of Veterans Affairs hospitals, as well as hospital units of institutions (such as prison hospitals), and hospitals with fewer than six beds staffed for patient use, are excluded.
In surveys such as the NHDS, the calculated standard error for small samples can be substantial. For 1995, NHDS estimates less than 5000 generally have a relative standard error of more than 30% or are based on a sample of fewer than 30 cases. For 1995, NHDS estimates of 5000 to 9000 are generally based on fewer than 60 cases with subsequently low reliability. In cases where the error exceeds 30%, the numbers are not provided and, as a result, the sum of component numbers may only approximate the given total. Small sample errors are also pronounced due to the rounding of survey data to the nearest thousand.
In many cases, as with the NHDS, data also tends to understate the "real" patient population. One of the limitations of the NHDS is the trend to perform procedures in an ever-increasing number of free-standing surgical centers and office-based settings. Another limitation is that the NHDS data is only focused on hospital data that does not necessarily reflect the true patient population for diseases such as asthma where patients are seldom admitted to hospitals. To overcome such limitations, TDR continuously compiles entries from various other sources to give users a broader understanding of the topic.
