Analysing health system capacity and preparedness for climate change

Abstract

While increasing literature demonstrating the direct and indirect impacts of climate change focuses on health, the capacity and preparedness of healthcare systems to deal with these impacts are less frequently considered. Here we performed a systematic analysis of peer-reviewed and grey literature to assess the current and projected coping capacity for healthcare systems under climate change. Data from the 129 included publications focused broadly on seven topics: workforce, tools and frameworks, infrastructure and urban planning, communication, surge capacity and increased system burden, service interruption and financial costs. Publications were biased towards high-level representation of acute disaster events, particularly in Global North countries. Non-peer-reviewed literature such as policy and planning documents, which may offer further insights into preparedness, were under-represented and could be a feature of next-generation research. Health systems need to be future proofed through effective policies, adequately trained workforces and redesigned infrastructure to meet the increasing burdens of climate change.

Extended data

Extended Data Fig. 1 Included publications by year of publication, and trendline.

Results showing the number of publications by year, and the trend in publications. The graph includes publications between 1990 and May 2022, resulting in fewer publications identified in the final year.

Extended Data Fig. 2 Comparison of tropical cyclone-specific publications to other weather and disease-related publications by topic.

Number of tropical cyclone-specific publications (including hurricanes, typhoons, and tropical storms) discussing one or more of the seven topics identified from the full literature set compared to those discussing other climate-related impacts (for example, droughts, floods, heatwaves, vector-bone diseases). Filled bars represent tropical-cyclone specific publications. Unfilled indicates all other publications.

Extended Data Fig. 3 Percentage of publications covering key topics at each health system level.

Percentage of publications discussing identified topic areas from the included literature within a specific level of the health system (micro: ranging from the clinic or department level to whole hospital or facility level; meso: ranging from a local governance level to the provincial or state level; macro: at the whole-system, or at the national to global level).
