title: Patients with community acquired pneumonia discharged from the emergency department according to a clinical practice guideline.
abstract: OBJECTIVE
  To assess the safety of discharging patients with community acquired pneumonia (CAP) according to a clinical practice guideline.
  
  
  METHODS
  A systematic retrospective review of medical records of 867 adult patients discharged from an emergency department (ED) with CAP between 3 January 1999 and 3 January 2001. Readmission or death rates within 30 days of discharge were evaluated, using data from all local hospitals and from the provincial coroner.
  
  
  RESULTS
  Of 685 patients with pneumonia severity index (PSI) scores of <91, 13 (1.9%) were readmitted and five (0.76%) died within 30 days of the ED visit. Thirty day readmission and death rates for patients with PSI >90 were 7.14% (13 of 182) and 9.34% (17 of 182), respectively.
  
  
  CONCLUSIONS
  Adult patients with CAP discharged from the ED according to the recommendations of a clinical practice guideline based on the PSI have low readmission and death rates, and are generally safely managed as outpatients.
