How this fits in

It is uncertain which strategies have the greatest potential to reduce the use of low-value medical tests in primary care settings. The evidence from the randomised controlled trials in this review indicates that it is possible to reduce the use of low-value medical tests in primary care, particularly by combining multiple intervention components, including reminders and audit/feedback, and by targeting patients. However, to implement these strategies widely in primary care settings, more research is needed to investigate adverse events, cost-effectiveness, and patient-reported outcomes as consequences of reducing the use of low-value medical tests.
