Improving Quality in Cardiac Arrest via Resuscitation Academy Training (IQ-CART): Study Protocol for a Mixed-Methods Study With a Focus on Low-Performing EMS Agencies.
Article in Circulation. Cardiovascular quality and outcomes, 2025. 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
backgroundGiven the large variation in out-of-hospital cardiac arrest (OHCA) survival, the Resuscitation Academy has developed a comprehensive training and mentorship program for emergency medical service (EMS) agencies to improve OHCA care. This study will evaluate whether Resuscitation Academy training is associated with higher OHCA survival at EMS agencies, particularly those with lower OHCA survival.
methodsWithin the Cardiac Arrest Registry to Enhance Survival, we will conduct a prospective mixed-methods study of EMS agencies participating in Resuscitation Academy training between October 2024 and December 2026 with ≥2 years of OHCA data collection and ≥20 OHCAs annually. Enrollment of EMS agencies with low baseline OHCA survival and diverse sociodemographic and socioeconomic characteristics will be prioritized, with a goal of 100 enrolled agencies. Changes in OHCA survival (primary outcome: survival to hospital admission) between EMS agencies enrolled in the Resuscitation Academy, compared with control agencies, will be compared using a difference-in-difference analysis. We will also quantify changes in processes of care within individual Resuscitation Academy domains to identify those most strongly associated with survival improvement. Finally, we will identify facilitators and barriers to implementation of Resuscitation Academy recommendations through in-depth semistructured interviews with key stakeholders (EMS director, medical director, dispatchers, quality improvement director, and paramedics).
resultsAs of December 31, 2024, 15 EMS agencies have been prospectively enrolled. Twelve (80.0%) had below median OHCA survival rates to hospital admission (<24.9%), 5 (33.3%) had catchment areas that were majority (>50% of residents in the EMS catchment area) Black or Hispanic, and 7 (46.7%) served communities with below median annual household income (<$71 623) levels.
conclusionsThis study will provide key insights for a potential intervention to improve OHCA survival, especially at EMS agencies with lower survival. Moreover, it may serve as a roadmap for the evaluation of future health policy investments to improve OHCA care and reduce disparities.
