title: A six-year epidemiologic review of pneumonia in Department of Veterans Affairs facilities.
abstract: OBJECTIVE
  Pneumonia and acute lower respiratory infections are a major problem in the United States and worldwide. As one of the largest health care organizations in the United States, the Department of Veterans Affairs is an ideal location for an epidemiologic review of pneumonia over an extended period of time.
  
  
  METHODS
  Data for this study were retrieved from the Department of Veterans Affairs Austin Automation Center, the central repository for patient data in the Veterans Health Administration (VHA). In addition, specific data regarding penicillin-resistant Streptococcus pneumoniae in VHA facilities were obtained from an annual electronic nationwide census.
  
  
  RESULTS
  The case rate of pneumonias as a discharge diagnosis increased during the 6-year period. For the diagnosis group of bronchopneumonia and pneumonia with organism unspecified, the largest subset examined, total numbers and rates for this specific diagnosis increased during the study period. When fiscal year (FY)91 and FY96 were compared, rates increased for three diagnoses: overall pneumonia, pneumonia in infectious diseases classified elsewhere, and pneumococcal pneumonia. Decreases in rates occurred between FY91 and FY96 for pneumonia caused by other specified organisms and other bacterial pneumonia. The total number of discharges from VHA facilities decreased during the 6-year period.
  
  
  CONCLUSIONS
  The numbers of episodes of bronchopneumonia and pneumonia with organism unspecified, the largest pneumonia subset, increased during the 6-year period to greater than 27,000 cases. As the number of total discharges from the VHA decreased, the combination of increasing actual numbers and decreasing discharges yielded increased rates for overall pneumonia and certain subsets. These data should be useful in developing aggressive preventive strategies.
