This study systematically maps empirical research on physicians' views and experiences of hedging-type defensive medicine, which involves providing services to reduce perceived legal risks. The study identified common hedging-type practices among physicians, such as ordering unnecessary tests and treatments, suggesting invasive procedures against professional judgment, and excessive documentation in medical records. Potential solutions to defensive medicine were explored at macro, meso, and micro levels, with areas for future research including qualitative studies and intervention research.
This study systematically maps empirical research on physicians' views and experiences of hedging-type defensive medicine, which involves providing services (eg, tests, referrals) to reduce perceived legal risks. Such practices drive over-treatment and low value healthcare. Data sources were empirical, English-language publications in health, legal and multi-disciplinary databases. The extraction frame-work covered: where and when the research was conducted; what methods of data collection were used; who the study participants were; and what were the study aims, main findings in relation to hedging-type defensive practices, and proposed solutions. 79 papers met inclusion criteria. Defensive medicine has mainly been studied in the United States and European countries using quantitative surveys. Surgery and obstetrics have been key fields of investiga-tion. Hedging-type practices were commonly reported, including: ordering unnecessary tests, treatments and referrals; suggesting invasive procedures against professional judgment; ordering hospitalisation or delaying discharge; and excessive documentation in medical records. Defensive practice was often framed around the threat of negligence lawsuits, but studies recognised other legal risks, including patient complaints and regulatory investigations. Potential solutions to defensive medicine were identified at macro (law, policy), meso (organisation, profession) and micro (physician) levels. Areas for future research include qualitative studies to investigate the behavioural drivers of defensive medicine and intervention research to determine policies and practices that work to support clinicians in de-implementing defensive, low-value care.
