Abstract BackgroundAccording to the Centers for Disease Control and Prevention, patients admitted to the hospital are commonly discharged on antibiotic therapy with prolonged courses of therapy, which contributes to excessive antibiotic exposure and adverse events. The purpose of this study was to evaluate total antibiotic duration of therapy at hospital discharge at Indiana University Health Arnett, White Memorial, and Frankfort hospitals. MethodsA multicenter, retrospective electronic health record review was conducted from 1 January to 30 June 2019. Patients were included if they were at least 18 years of age, began antibiotic therapy while admitted, and continued antibiotic therapy at hospital discharge for 1 of the following indications: skin/soft tissue infection (SSTI), urinary tract infection (UTI), community-acquired pneumonia (CAP), or acute exacerbation of chronic obstructive pulmonary disease (AECOPD). The number of days of therapy (DOT) of each inpatient and outpatient antibiotic prescribed was collected to calculate the total DOT, which was utilized to determine the appropriateness of the duration of therapy. ResultsOf the 547 patients included, 233 patients (42.6%) had CAP, 120 (21.9%) had UTI, 101 (18.5%) had SSTI, and 93 (17%) had AECOPD. The median duration of antibiotic therapy across all indications was 9 days (interquartile range [IQR], 7–11). Median duration for CAP was 9 days (IQR, 7–10), AECOPD was 7 days (IQR, 5–9), UTI was 8 days (IQR, 6–10), and SSTI was 12 days (IQR, 10–14). ConclusionsExcess antimicrobial duration at hospital discharge represents an unmet need of antimicrobial stewardship programs. We reviewed the total duration of antibiotic therapy in 547 patients at the time of hospital discharge. When combining inpatient and outpatient days of therapy, antibiotic duration for common types of infection is excessive compared with recommendations from clinical practice guidelines.
