title: HIV infected hospital patients in New York State. The development of longitudinal information from a hospital discharge data system.
abstract: Abstracted records of all patients discharged from New York State acute care hospitals from January 1, 1983, through October 1, 1987, containing a diagnosis of HIV infection (N = 36,664) were linked into a longitudinal file of 20,005 patient-specific case histories. A validation study utilizing Medicaid patient-specific discharge information for calendar year 1985 showed that, on the average, each case history of the longitudinal file contained 85% (+/- 5%) of the expected discharges. The number of patients present in the longitudinal file was 10% (+/- 4%)--too large a percentage, due to a failure to link all the discharges to the appropriate case histories. The number of patients with a diagnosis of Pneumocystis carinii pneumonia (PCP) found in the longitudinal file was found to be consistent with the number reported to the New York State AIDS Registry. The longitudinal file appears to be sufficiently accurate and complete to use in evaluating HIV-related acute care in hospitals.
