Trends of non-union and prescriptions for non-steroidal anti-inflammatory drugs in the United States, 1993–2012

摘要

Background and purpose — Surgical care and pain management for patients with fractures have evolved over the years. We wanted to ascertain if there were any changes in the incidence of non-unions and, if so, whether the use of non-steroidal anti-inflammatory drugs (NSAIDs), including COX-2 selective inhibitors, might have an effect.Patients and methods — We used the National Inpatient Sample (NIS) to estimate the annual number of patients hospitalized for surgical treatment of a non-union between 1993 and 2012, and calculated age-adjusted rates of non-union. We estimated the prevalence of prescriptions for NSAIDs from 1996 through 2012 using the Medical Expenditure Panel Survey (MEPS). The interrupted time-series analysis was used to relate quarterly rates of non-union to changes in prescriptions for NSAIDs between 1996 and 2009.Results — The annual estimate of non-unions in the USA declined 30% from 25,634 in 1993 to 17,815 in 2012 (p 0.001). Specifically, the age-adjusted rate of non-unions decreased ...
