HSRAANZ WEBINAR SERIES: Cluster Randomised Trial on GP Feedback for Musculoskeletal Imaging Requests

18-month cluster randomised controlled trial that included 3819 GPs who had high request rates for 11 commonly overused musculoskeletal diagnostic imaging tests. GPs were randomised to receive feedback on their request rates or no intervention. A factorial design enabled evaluation of two variations of feedback: frequency of delivery (once vs twice) and visual design (standard vs enhanced). Feedback led to a 9% relative reduction in ordering rates of the 11 imaging tests overall at 12 months compared with control (adjusted mean difference −2.66 [95% CI, −3.24 to −2.07]; P less than .001). Feedback delivered twice and enhanced display led to additional modest reductions in ordering rates.
