Measuring environmentally sustainable health care: a scoping review

Work to reduce environmental pollution from the health system is hampered by an absence of consensus on the definition of environmentally sustainable health care and the relevant measurement needed. This scoping review aims to encourage standardisation across sustainability efforts by examining how environmentally sustainable health care is defined and measured in current literature. We conducted a scoping review to identify candidate publications that included either a definition or description of environmentally sustainable health care or a measurement of the impact of health care on the environment. 328 publications were included in the final analysis. 52 publications included definitions or descriptions of environmentally sustainable health care. Results of the study highlight the heterogeneity in the current definition, measurement, and measurement calculation methods of environmentally sustainable health care in published literature. Work is needed to create more harmonised definitions and measurement to support progress and reduce environmental pollution from health care.
