Sentinel Physicians for the Environment: A Chilean Perspective to Address Global Health and Climate Resilience.
Article in International journal of environmental research and public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Climate change and environmental degradation are intensifying health risks across Latin America, placing increasing pressure on primary health care (PHC) systems. Physicians working at community level are often the first to observe climate- and environment-related health effects, yet operational models that link clinical practice, environmental surveillance and community engagement remain insufficiently defined. This article adopts a policy-oriented narrative synthesis approach, drawing on peer-reviewed literature, policy documents, institutional records, memoranda of understanding, and outputs from professional seminars and stakeholder meetings conducted between 2024 and 2025 to develop an evaluable operational framework. Chile is examined as a case study, while the proposed framework is situated within a broader Latin American perspective. We conceptualise the model of Sentinel Physicians for the Environment (SPEs) as an operational framework embedded within PHC, structured around four core pillars: surveillance, prevention, communication and advocacy. The model clarifies how SPEs can contribute in practical terms to addressing major climate-related health threats, including heatwaves, air pollution, wildfires, vector-borne diseases, migration-related vulnerability, antimicrobial resistance and zoonotic risks. The Chilean experience illustrates feasible implementation pathways, distinguishing actions already undertaken, initiatives under development and proposed future steps. The SPE model offers a pragmatic and scalable approach to strengthening climate-resilient primary health care in Latin America. By leveraging existing PHC structures and community trust, SPEs can enhance early detection, risk communication and preparedness without requiring complex technologies or high financial investment, providing a transferable contribution to public health practice and policy, with clear implications for future evaluation.
