Surgical smoke: how an issue in healthcare fits a planetary health framework

Abstract

Aim: The smoke generated from electrocautery machines may be harmful to health. Healthcare in general, and surgery in particular, has a large environmental footprint. The aims of this study were to discover what healthcare workers thought about the problem of electrocautery smoke, the idea of a surgical smoke-free policy, and to formulate ideas on how the matter could be approached in an environmentally and socially responsible way. METHOD: Operating room personnel in a tertiary referral hospital were invited to complete a survey about electrocautery smoke: perceived risks, current exposure, and measures to minimise exposure. Quantitative data were analysed in a generalised linear model, and qualitative data by reflexive thematic analysis within a constructivist theoretical framework. RESULTS: The survey response rate was 463/1234 (38%). Most supported a smoke-free policy (89%). Support for a policy was positively correlated with the perceived risk of electrocautery smoke (p<0.001. Support was lower amongst males (p<0.05). Themes from the qualitative analysis developed around nature, society and technology. A framework was developed consisting of earth and its ecosystems, human health, governance, economics, society, and the interconnected of these systems. CONCLUSION: Although smoke-free policies form part of the solution to electrocautery smoke, they are not the whole solution. Healthcare issues, in this case the issue of electrocautery smoke, could be tackled within a planetary health healthcare framework, promoting a systems approach. Applicability of the framework requires confirmation by further research.
