Improving Environmental Sustainability of Operating Theatres: A Systematic Review of Staff Attitudes, Barriers, and Enablers.

Objective: To understand views of staff in relation to attitudes, enablers, and barriers to implementation of environmentally sustainable surgery in operating theatres. This will ultimately help in the goal of successfully implementing more sustainable theatres.

Background: Global health care sectors are responsible for 4.4% of greenhouse gas emissions. Surgical operating theatres are resource intensive areas and improvements will be important to meet Net-Zero carbon emissions within health care.

Methods: Three databases were searched (Web of Science, Ovid, and PubMed), last checked January 2024. We included original manuscripts evaluating staff views regarding sustainable operating theatres. The Mixed Methods Appraisal Tool was used for quality appraisal and data analysed using thematic synthesis.

Results: A total of 2933 articles were screened and 14 fulfilled inclusion criteria, using qualitative (1), quantitative (2), and mixed methods (11). Studies were undertaken in a variety of clinical (Department of Anaesthesia, Surgery, Otolaryngology, Obstetrics and Gynaecology and Ophthalmology) and geographical settings (Australia, Canada, France, Germany, New Zealand, United States, United Kingdom, and Ireland). Across studies there was a lack of evidence exploring enablers to implementation, but barriers mainly related to the following themes: education and awareness, leadership, resistance to change, facilities and equipment, time, and incentive.

Conclusions: This systematic review identified attitudes and barriers perceived by clinicians towards improving environmental sustainability within operating theatres, which may inform future strategy towards sustainable surgery. Most studies used a survey-design, whereas use of interviews may provide deeper insights. Future work should be extended to wider stakeholders influencing operating theatres. In addition, implementation studies should be carried out to examine whether barriers do change in practice.
