Climate change and health care facilities: A risk analysis framework through a mapping review.

INTRODUCTION

Climate change (CC) has been identified as the biggest global health threat of the 21st century. Although health care facilities (HCF) play a central role in the care of populations, there has been no comprehensive assessment of the impact of CC on HCF. The objective of our study was to highlight the components of HCFs affected by CC through a mapping review of the literature.

METHODS

To meet our objective, we first assessed the place of HCFs in relation to CC in the scientific literature and in the Intergovernmental Panel on Climate Change (IPCC) reports. Bibliometric data from the PubMed database were analyzed between 1979 and 2021 to assess the penetration of keywords on CC alone, and in relation to health and HCF in particular. Second, we analyzed the changes in HCF keywords in the IPCC reports. Finally, we conducted a mapping review in five databases, of the international scientific literature published between 1979 and 2019, and identified the components of HCF affected by CC using the Ishikawa diagram.

RESULTS

From the 2000s, the number of publications on CC and HCF increased gradually with 137 articles in 2005, and even more sharply since 2008 with 358 articles published and 813 in 2021. Even though CC is only recently present in the biomedical literature, all climatic events (warming and heatwaves, droughts, wildfires, storms, hurricanes and cyclones, floods and sea-level rise, and other indirect effects) have had an impact on at least one component of HCF.

CONCLUSION

HCFs are already impacted, in all their components, by CC. By enhancing our understanding of the impacts of CC on HCF, this work could contribute to the engagement of health professionals in the implementation of mitigation and adaptation actions, thereby limiting the consequences of CC on patient care.
