Environmental Scanning of Climate Adaptation Tools in Healthcare

Introduction: Extreme weather events are increasing in frequency and intensity due to climate change, contributing to substantial morbidity and mortality globally, particularly among vulnerable populations. In the UK, climate adaptation within health systems remains insufficiently developed. However, there is limited understanding of the tools currently available for the identification and management of populations at risk during extreme weather. This study aims to systematically characterise UK-based climate adaptation tools used in healthcare settings. Methods: Environmental scanning was conducted, because no centralised database exists for climate adaptation tools in healthcare, and many relevant resources are not captured in traditional academic or grey literature repositories. Structured Google searching by two independent reviewers enabled identification of publicly available and practice-oriented tools accessed in real-world settings. Eligible resources included UK-based tools designed for healthcare professionals, local authorities, or patients that incorporate meteorological data to mitigate climate-related health risks. Results: Nine tools met inclusion criteria, comprising e-learning platforms, online dashboards, integrated clinical software, and structured workflows. Most targeted healthcare professionals, with few targeting local authorities and none targeting patient self-management. Data inputs and outcomes measures were heterogeneous, spanning risks related to heat, cold, flooding, and air pollution. Reporting was inconsistent, as nearly half the tools were not publicly accessible and all demonstrated limited transparency. Conclusion: The current landscape of UK climate adaptation tools in healthcare is fragmented, with variability in accessibility, evidence, and scope. Clearer reporting and greater coordination in how such tools are catalogued may support more consistent and equitable responses to climate-related health risks.
