title: [Results of a comparison: active versus passive reporting in cases of community acquired pneumonia. Results of the German Competence Network CAPNETZ].
abstract: BACKGROUND
  Since 2002, the German competence network CAPNETZ has been collecting data from inpatients and outpatients with community acquired pneumonia (CAP) at eight local clinical centres. Contrary to the literature reports, the proportion of outpatients in CAPNETZ averages out at 28 %. Therefore, this study determines whether an active reporting system can increase the number of cases reported in medical practices.
  
  
  METHODS
  In ten medical practices in Lübeck, the passive reporting system was changed to an active reporting system consisting of a) a weekly announcement of CAP cases including negative reporting, b) a study nurse who was responsible for the reporting, c) additional payment, d) a telephone call after two weeks by absent announcements and e) incentives like benchmarking or additional information. The number of the reported cases between the active reporting period (2004) and the same period in the year before was recorded.
  
  
  RESULTS
  The number of reported cases increased in eight of the ten medical practices. Overall 72 CAP cases were reported, 33 % more than in the period of passive reporting. The number of patients encompassed in CAPNETZ increased from 17 to 34.
  
  
  CONCLUSIONS
  We did not find a comparable increase of CAP cases either in Lübeck overall (including inpatients) or in all the local clinical centres together. Thus, it is assumed that the increase of reported cases depends on the methodical effect.
