Background The climate emergency is a pressing threat to human health and health systems. Members of the Cochrane community must bring our evidence synthesis expertise to the work of supporting effective decision making to adapt to or mitigate its impacts. Because of the multi-level and systemic challenge of this topic, relevant evidence is complex and heterogeneous. Synthesis of this evidence requires appropriate methods that incorporate interdisciplinary approaches. Objective To introduce participants to the knowledge and skills needed to conduct comprehensive and rigorous evidence syntheses on climate-health topics. Participants will gain an understanding of available relevant evidence synthesis methods and will be introduced to the skills needed to conduct their own syntheses. They will also have the opportunity to network with other researchers and practitioners working in the field. Description Overview of key concepts and terminology - Introduction to climate change and human health linkages - Adaptation and mitigation initiatives related to health and health systems Decisions related to conducting a review: - Framing the PICO question - Search strategies and selecting databases - Incorporating logic models/conceptual frameworks to link health and climate variables - Decisions about scope (lumping versus splitting) and levels of analysis - Addressing equity considerations - Establishing a review advisory board There will be facilitated small-group work sessions addressing specific issues for designing a protocol on a climate-health question. Participants can bring their own topics or work from sample topics provided by the facilitators. The workshop will conclude with a brief discussion of future methods needs for climate-health syntheses.
