Background: Preventing overuse of magnetic resonance imaging (MRI) for diagnosing ankle pathology was the goal of a process improvement project at a military treatment facility.
Methods: Ordering patterns for MRI of nonorthopaedic providers and orthopaedic surgeons were evaluated over 2 separate periods. An educational initiative on appropriate use of MRI in evaluating ankle complaints was conducted between the 2 periods.
Results: Between October 2009 and March 2010, 230 ankle MRIs were performed at our institution, compared to 347 ankle MRIs performed between December 2012 and August 2013. A lower number of patients underwent operative procedures after the education process than before (17% versus 25%). Fellowship-trained foot and ankle surgeons produced the highest number of operative patients with their MRI ordering practices (P=.003 and P=.0001 for Phases 1 and 2 respectively). There was no change in the number of ankle MRI studies ordered each month following the educational initiative (38.3 and 38.5 for Phases 1 and 2 respectively).
Conclusions: The majority of patients undergoing ankle MRI did not undergo operative intervention. Foot and ankle surgeons produce the highest number of operative patients with their MRI ordering practices. Education alone was ineffective in altering ankle MRI ordering patterns.
