Community-acquired pneumonia (CAP) is a common illness with substantial mortality but also substantial impact on patient’s functional ability.  To date, no studies have documented the burden of CAP as measured by the time needed to return to work or usual activities as well as recovery time needed to return to full productivity.    


This study evaluated the time needed to return to work or usual activities and the recovery time needed to return to pre-CAP productivity levels. Five hundred older adults age ≥50 years diagnosed with CAP in the past 120 days were recruited from a large population-based internet panel and identified as CAP patients based on screening questions, including having had radiographs. Participants were asked about the burden of CAP measured by a newly-developed questionnaire.  Participants reported the number of days missed from work or usual activities and how many days it took to return to their usual level of job performance or activities.  The analysis was weighted for US population representativeness and stratified by care setting (hospitalized or outpatient) and risk for pneumonia (low vs. at-risk) based on self-reported comorbidities.


The mean age of CAP respondents was 62 years old, 45% were male, 19% were living alone, 53% had some college education and the mean time from pneumonia diagnosis was 57 days.  The main results are presented below:   






Low risk

% currently employed






% who missed work/usual activities






Median # of days of missed work/usual activities

14 days

7 days


10 days

8 days

Median # of days needed to reach usual performance

28 days

21 days


21 days

22 days


The average time lost from work or usual activities for CAP was at least one week regardless of hospitalization or risk classification.  The average time for patients to return to pre-CAP productivity levels was approximately two weeks longer than the recovery time needed to return to work or usual activities.
