    Background.

    Previous studies suggest that duration of antibiotic therapy for community-acquired pneumonia (CAP) often exceeds national recommendations and might represent an important opportunity to improve antibiotic stewardship nationally. Our objective was to determine the average length of antibiotic therapy (LOT) for patients treated for uncomplicated CAP in US hospitals and the proportion of patients with excessive durations.

    Methods.

    Records of retrospective cohorts of patients aged 18–64 years with private insurance and aged ≥65 years with Medicare hospitalized for CAP in 2012–2013 were used. Inpatient LOT was estimated as a function of length of stay. Outpatient LOT was based on prescriptions filled post discharge based on data from outpatient pharmacy files. Excessive duration was defined as outpatient LOT >3 days.

    Results.

    Inclusion criteria were met for 22 128 patients aged 18–64 years across 2100 hospitals and 130 746 patients aged ≥65 years across 3227 hospitals. Median total LOT was 9.5 days. LOT exceeded recommended duration for 74% of patients aged 18–64 years and 71% of patients aged ≥65 years. Patients aged 18–64 years had a median (quartile 1–quartile 3) 6 (3–7) days outpatient LOT and those aged ≥65 years had 5 (3–7) days.

    Conclusions.

    In this nationwide sample of patients hospitalized for CAP, median total LOT was just under 10 days, with more than 70% of patients having likely excessive treatment duration. Better adherence to recommended CAP therapy duration by improving prescribing at hospital discharge may be an important target for antibiotic stewardship programs.
