Abstract
Introduction Sustainability in healthcare is a rapidly developing area of research with recent formal recognition from institutions around the world. We completed an update of a systematic review published in 2020. The aims of this review were to determine the reported carbon footprints of surgical operations in hospitals worldwide, identify variations in reported carbon footprints and highlight carbon hotspots associated with surgery. Methods A systematic review was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. The MEDLINE®, Embase® and Cochrane Library databases were searched, and eligibility criteria applied. The study characteristics, scope of product inventory and results were extracted and synthesised. A quality assessment of each study was completed to inform the reliability of the research. Results 1,308 articles were identified and 7 met the inclusion criteria for the review. The carbon footprint ranged from 28.49kg to 505.1kg carbon dioxide equivalents (CO2e). Medical devices and consumables were the greatest contributor to emissions, with material production and manufacture representing the majority of this carbon hotspot. There were significant methodological limitations and a lack of consistency in carbon footprint calculations between studies. Conclusions This systematic review identifies medical devices and consumables as the largest carbon hotspot where healthcare providers should target their sustainability initiatives. Nevertheless, the number of studies was limited and the quality of the evidence was weak. We recommend that researchers in healthcare sustainability develop international standards for conducting and reporting such studies. This would allow for comparison of individual studies and facilitate meta-analysis of cumulative evidence. A reliable evidence base is a prerequisite for identifying optimal interventions to ensure societal benefits.
