Abstract:

The Army Medical Surveillance Activity assessed rates, trends, and correlates of risk of pneumonia hospitalizations among active duty soldiers during the period January 1990 through September 1996. Records of hospitalizations of solders source PASBA, Fort Sam Houston, Texas were searched to identify those with a principal discharge diagnosis of pneumonia International Classification of Diseases, 9th revision, codes 480-487 or a principal diagnosis of acute respiratory infection, e.g. pharyngitis, laryngitis, bronchitis, ICD-9 codes 460-466 and a secondary diagnosis of pneumonia. If soldiers had multiple pneumonia admissions, only the first was retained for analysis. Denominators for rate calculations were derived from semiannual 1990-1992 or monthly 1993- 1996 Army active duty personnel rosters source Defense Manpower Data Center, Monterrey, California. To assess geographic correlates of risk, we identified states of residence prior to entering military service for soldiers on active duty in the Army during the study period source Military Entrance Processing Command, North Chicago. Illinois. To determine if certain states were over or under-represented among pneumonia cases, for each state we calculated an expected number of cases by multiplying the states proportional representation among all soldiers by the total number of pneumonia cases. Variations between observed and expected cases were then calculated for each state, and the statistical significance of variations was assessed based on the chi-square distribution nominal statistical significance defined as p .05.
