Access to Nonphysician Led Exercise Stress Echocardiography Reduces Wait Times and Improves Consumer Engagement

The performance of nonphysician-led exercise stress testing with and without echocardiography has shown similar diagnostic utility and safety as physician-led models. While diagnostic accuracy and relative safety have been the focus of previous research, the current study aims to demonstrate efficiencies not previously reported, such as reduction in wait times for testing and improved service attendance. A nonphysician-led exercise stress echocardiography service was implemented on January 01, 2018; before this, all tests were performed under a physician-led model. Retrospective data was retrieved from both models (physician-led model from January 01, 2015 to December 31, 2017 and the nonphysician-led model from January 01, 2018 to December 31, 2023). Comparisons were made between the models regarding the number of tests performed, the average wait time to access testing, and the did not attend (DNA) rates. On average, 212 tests were performed in the physician-led model per year, with average wait times to access testing of 11.3 weeks and a DNA rate of 15.3%. In contrast, the nonphysician-led model performed on average 501 tests per year (135% increase) ( P < 0.001) with average wait times of 6 weeks (47% decrease) ( P < 0.01) and DNA rate of 4.8% (69% decrease). Despite the physician-led group displaying an overall higher cardiovascular disease risk, there were no adverse cardiovascular events at the time of testing in either model. Nonphysician-led exercise stress echocardiography remains as safe as physician-led models but demonstrates service improvements, including significant reductions in wait times and lower DNA rates.
