Eco-friendly treatment: a win-win for patients, health systems, and the planet. Rapid scoping review

Abstract Background As the fifth-largest CO2 emitter globally, the healthcare industry must act to mitigate its environmental impact. This includes de-implementing low-value care and adopting eco-friendly innovative treatment alternatives. Our study aims to explore existing research on the environmental effects of these actions and the outcome measures utilized. Methods We conducted a rapid scoping review following a pre-published protocol, searching Ovid MEDLINE® and Scopus (Elsevier) from January 2015 to June 19, 2023. Initially, dual abstract and full-text screening was performed, followed by a single review. Data extraction was cross-checked by a second reviewer. Findings were narratively described using summary statistics. Results We analyzed 182 articles, primarily life cycle assessments and modeling studies (92 out of 182), with only one study being a randomized controlled trial. The research covered various healthcare practices, including consultation methods/telemedicine (32%), surgical and medical device usage (26%), medication (25%), surgical procedures (19%), as well as diagnostic tests, screening, and imaging (13%). The main sustainability strategies mentioned were ‘Rethink’ (99%) and ‘Reduce’ (81%), with ‘Reuse’ (32%), ‘Recycle’ (19%), and ‘Refuse’ (10%) being less utilized. Environmental outcomes reported included global warming (88%), resource consumption (27%), and chemical hazards (23%). Most studies were conducted in Europe (48%), followed by the USA (37%), with 75% published after 2020. Conclusions The environmental impact of healthcare is a pivotal area for public health action and fortunately, it is also emerging as a significant research field. Utilizing methodological approaches less common in evidence-based healthcare research underscores the necessity for innovative interdisciplinary collaboration and capacity building. The most pressing research gap lies in the impact of de-implementation strategies (“refuse”) targeting low-value care practices. Key messages • Measuring the environmental impact of healthcare demands the development of novel cross-disciplinary research methods and collaborations. • De-implementing low-value care represents a future win-win scenario for patients, the financial viability of healthcare systems, and global environmental sustainability.
