Out-of-hospital cardiac arrest in three EMS centers in northern and central Thailand: a mixed-methods call for a national data infrastructure.
Article in BMC emergency medicine, 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
backgroundOut-of-hospital cardiac arrest (OHCA) is a leading cause of mortality in Thailand, yet national response to the issue remains fragmented and under-prioritized. There is no centralized OHCA registry, neurological outcome data are almost entirely absent, and coordination between EMS and hospitals is weak. This limits Thailand's ability to evaluate performance, guide investments, or improve survival.
methodsWe conducted a convergent mixed-methods study combining retrospective analysis of OHCA registry data (n = 2,259) from three hospital sites participating in a regional OHCA registry (2017-2023) with in-depth qualitative interviews across EMS, hospital, and policy stakeholders. Quantitative data were analyzed for trends in bystander CPR, response and scene times, and outcome tracking. Qualitative data were thematically coded to identify structural and operational barriers to data use and system integration.
resultsNeurological outcome data were available for only 16.4% of patients who were alive at 30 days. EMS teams had limited access to in-hospital outcome information, and hospitals did not routinely track functional recovery. One suburban-capital hospital showed measurable improvement using internal data to reduce scene times and increase bystander CPR. However, systemic fragmentation undermined scalability. Across sites, EMS and hospital data systems were not interoperable, and OHCA care was inconsistently prioritized.
conclusionThailand's OHCA system shows both promise and constraint. These findings highlight the need for improved data infrastructure, including standardized outcome tracking, better linkage between EMS and hospital systems, and clearer governance. Local successes can serve as models, but only with political will, shared infrastructure, and clear governance. A national OHCA data strategy is essential to improve survival and achieve equitable care.
