Although guidelines have been developed for imaging, they are primarily based on expert opinion rather than evidence26,27 and have not been shown to reduce imaging.28 Imaging examinations are frequently adopted into clinical practice before evidence supports their use, and once incorporated into practice, withdrawing their use is difficult. For example, among older adults in the United States, CT increased from 204 per 1000 person-years in 2000 to 428 per 1000 person-years in 2016 (relative rate for 2016 compared with 2000, 2.1; 95% CI, 2.0-2.2), and in Ontario, CT increased from 161 to 409 per 1000 person-years (relative rate, 2.5; 95% CI, 2.4-2.7).
