Progress, challenges, and lessons for climate resilient and low carbon health systemsin Latin America and the Caribbean: an exploratory mixed-methods study.

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
objectiveTo assess progress, challenges, and enabling factors for building climate-resilient and low-carbon health systems across Latin America and the Caribbean, a region facing accelerating climate-sensitive health burdens amidst persistent health system fragilities.
methodsWe conducted an explanatory, sequential, mixed-methods study integrating quantitative analysis of the Pan American Health Organisation Climate Change and Health surveys from 2021/2022 (n = 24 countries) and 2023/2024 (n = 27 countries) with semi-structured interviews involving four countries demonstrating progress (Argentina, Chile, Jamaica, Peru). Quantitative data were analysed descriptively across three sub-regions (Caribbean, Central America, South America). Qualitative data underwent two-stage coding (deductive and inductive) with three-researcher consensus to identify barriers, enablers, and lessons learned.
resultsBy 2023/2024, 93% of countries had designated climate-health focal points (71% in 2021/2022). However, implementation gaps persist: less than 50% of countries had integrated climate change into national health reports; 22%-40% developed national climate-health strategies; and vulnerability assessments rarely informed policy. Access to international climate finance remained inequitable. Whilst 60%-74% developed disaster preparedness plans, only 30%-44% implemented public health communication campaigns. Training focused on environmental health personnel, with doctors, nurses, and planning staff minimally engaged. Qualitative analysis revealed interconnected barriers: climate change perceived as distant rather than urgent, competing priorities overwhelming decision-makers, institutional silos, and misalignment between available training and local needs. Key enablers included linking climate action to established health priorities, institutionalising responsibilities through formal mechanisms, multi-stakeholder engagement, and committed individuals with diplomatic skills navigating cross-sectoral dynamics.
conclusionLatin America and the Caribbean countries are establishing foundations for climate-resilient and low-carbon health systems, but translating governance progress into sustained implementation requires addressing systemic barriers through institutionalisation beyond political cycles, tailored capacity building, and innovative financing mechanisms. These findings inform guidance for health systems strengthening amidst accelerating climate change.
