"Aim
Climate change is the most pressing global challenge of the twenty-first century and has recently been declared as a public health emergency due to its widespread environmental, social, economic, and health impacts. This scoping review aims to map existing evidence on the impact of climate change on health workers.
Subject and methods
We followed the JBI guidelines for scoping reviews and the PRISMA-ScR protocol. Systematic searches were conducted in databases including PubMed, MEDLINE, ProQuest, SCOPUS, Web of Science, EMBASE, CINAHL and PsycINFO. Peer-reviewed articles published between 01 January 2014 and 03 May 2024 were included. The findings were presented numerically and thematically, and a narrative synthesis summarised the evidence.
Results
We analysed 23 studies from different regions and identified four main areas of climate change impacts: physical health impacts, mental health impacts, occupational safety impacts, and impacts on the capacity and resilience of health workers. This review also identified barriers and challenges to health workers' ability to respond to climate change, including time constraints, gaps in knowledge and training, strains on infrastructure and supply chains, difficulties in resource allocation, and coordination challenges between organisations.
Conclusion
The review highlights the substantial physical health, mental health, and occupational safety impacts of climate change on health workers. These effects undermine the resilience of health workers and the operational integrity of health services. To increase health workers' resilience to climate change impacts, it is essential to implement a comprehensive strategy that includes targeted training, infrastructure upgrades, policy updates, and improved inter-agency coordination."
