Update on Medical Overuse

IMPORTANCE Overuse of medical care, consisting primarily of overdiagnosis and overtreatment, is a common clinical problem. OBJECTIVE To identify and highlight the most significant clinical articles published in 2013 related to medical overuse. EVIDENCE REVIEW A systematic review of English-language articles published in 2013 that related to medical overuse in adults. FINDINGS We reviewed 478 published articles that met our inclusion criteria. Of these, 126 were ranked most relevant based on quality of methodology, strength of results, potential effects on patient care, and the number of patients potentially affected. The 10 most relevant articles were selected using the same criteria. These 10 articles (organized into the categories overdiagnosis, overtreatment, and methods to avoid overuse) were reviewed and interpreted for their effect on clinical medicine. CONCLUSIONS AND RELEVANCE The literature on overuse of medical care is rapidly expanding. In 2013, both clinical trials and observational studies highlighted frequently overused or unnecessary care. Overuse of testing causes false-positive results and overdiagnosis. Negative test results do not appear to genuinely reassure patients. Overtreatment, with both medical therapies and procedural interventions, places patients at risk of unnecessary adverse events.
