Objective: This study has objectives to study the prevalence and factors associated with adverse outcomes in discharged patients with community-acquired pneumonia (CAP) at the emergency department, Vajira hospital.

Method: This was a retrospective chart review from January to December 2014. Medical records of over 14-year-old CAP patients who were diagnosed and discharged at emergency department were reviewed in 130 records. The severity was categorized according to CRB-65. We analyzed factors that correlate to adverse outcomes.

Results: Prevalence of adverse outcomes in discharged patients with CAP was 24 (18.5%). Eighteen of 24 (12.3%) revisited in outpatient clinic and six of 24 (6.2%) needed admission. Ten of 24 (7.7%) had adverse events within 72 hours. The factors that significantly related to adverse outcomes in patients with CAP were the severity at first ED presentation (p< 0.01) and chronic obstructive pulmonary disease (COPD) (p= 0.023).

Conclusion: The factors associated to adverse outcomes in discharged CAP patients are moderate severity of CAP and COPD. The CAP patients who has either one of these factors need more assessment and close follow up.
