摘要
IMPORTANCE Estimates of the incidence of overall antibiotic-associated adverse drug events (ADEs) in hospitalized patients are generally unavailable. @@@ OBJECTIVE To describe the incidence of antibiotic-associated ADEs for adult inpatients receiving systemic antibiotic therapy. @@@ DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort of adult inpatients admitted to general medicine wards at an academic medical center. @@@ EXPOSURES At least 24 hours of any parenteral or oral antibiotic therapy. @@@ MAIN OUTCOMES AND MEASURES Medical records of 1488 patientswere examined for 30 days after antibiotic initiation for the development of the following antibiotic-associated ADEs: gastrointestinal, dermatologic, musculoskeletal, hematologic, hepatobiliary, renal, cardiac, and neurologic; and 90 days for the development of Clostridium difficile infection or incident multidrug-resistant organism infection, based on adjudication by 2 infectious diseases trained clinicians. @@@ RESULTS In 1488 patients, the median age was 59 years (interquartile range, 49-69 years), and 758 (51%) participants were female. A total of 298 (20%) patients experienced at least 1 antibiotic-associated ADE. Furthermore, 56 (20%) non-clinically indicated antibiotic regimens were associated with an ADE, including 7 cases of C difficile infection. Every additional 10 days of antibiotic therapy conferred a 3% increased risk of an ADE. The most common ADEs were gastrointestinal, renal, and hematologic abnormalities, accounting for 78 (42%), 45 (24%), and 28 (15%) 30-day ADEs, respectively. Notable differences were identified between the incidence of ADEs associated with specific antibiotics. @@@ CONCLUSIONS AND RELEVANCE Although antibioticsmay play a critical role when used appropriately, our findings underscore the importance of judicious antibiotic prescribing to reduce the harm that can result from antibiotic-associated ADEs.
