Variability in Deposition Rates and Mean Days of Hospitalization for the 100 Most Common Diagnostic Codes in U.S. Army Health Services Command Facilities.

摘要

U.S. Army Health Services Command (HSC) is the operational medical major command responsible for all Army medical treatment facilities (MTF); providing comprehensive health care for more than 3 million beneficiaries. The period chosen for analysis is calendar year 1989 (CY89). The purpose of studying utilization rates such as those detailed in this report is to provide data which can be used to improve clinical quality and to reduce unnecessary resources utilization by identifying unusual patterns of variation. These studies identify possible problem areas for further evaluation. Small Area Analysis typically addresses variability in three major areas: disposition rates, bed day utilization, and costs. Due to the mechanisms through which military facilities are funded, cost information cannot be obtained for specific individual diagnoses or procedures. U.S. Army Patient Administration Systems and Biostatistics Activity (PASBA) maintains statistical records for all Army facilities. The PASBA provided a list of the 100 most common diagnoses, based on ICD-9-CM code, for HSC during CY89. All codes where based on primary diagnoses. The data appear to show that of the 100 most common diagnostic codes in HSC, some codes show great inconsistency in disposition rates or bed days or both and other codes that show very little variability in either.
