Social determinants and pre-arrest care patterns associated with cardiac arrest and mortality.

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
backgroundUnderstanding the impact of social determinants of health (SDOH) on CA, including access to care pre-cardiac arrest (CA) can improve outcomes. Large databases, such as Epic Cosmos, can help identify trends in patient demographics and SDOH that identify gaps in care. The purpose of this study was to determine the incidence of CA and subsequent mortality in a large national database across patient demographics and social determinants and characterize pre-arrest care patterns.
methodsThis was a retrospective cohort study using a large national deidentified electronic health database (Epic Cosmos) with 227 million patients. Inclusion criteria was ED encounter for CA (ICD-10-CM: I46). Patient demographics and social determinants included age, sex, race, ethnicity, social vulnerability index (SVI, a composite measure with greater SVI representing more vulnerability). The primary outcome was difference in CA incidence between groups, reported as odds ratios (ORs). The secondary outcomes were 1) incidence of pre-arrest care within 30 days and 2) post-arrest mortality at 7,30, and 180 days. Statistical analysis was performed using Chi-squared analysis (unadjusted OR) and aggregated logistic procedure (adjusted OR).
resultsThere were 201,846 ED visits for CA between April 20, 2020, and April 19, 2023 (0.11% incidence). For all ages, males had a higher incidence of CA (OR 1.76, p < 0.0001). Black, Native Hawaiian or Pacific Islander, and American Indian or Alaska Native had a higher OR of CA while Asian patients were less likely than White patients (adjusted OR 1.85, 1.44,1.51, and 0.81 respectively, all p < 0.0001). Hispanic/Latino patients had a lower OR of CA (adjusted OR 0.72, p < 0.0001). CA was more common in the highest SVI quartile compared to the lowest (adjusted OR 1.71, p < 0.0001). Significant heterogeneities were identified in pre-arrest care across patient demographics and social determinants, where ED visits were more common than office visits among male patients, patients in the highest SVI, Hispanic/Latino, and minority patients, except for Asian patients. Post-arrest mortality after 30 days was highest in females, Black patients, and patients in the highest SVI.
conclusionsSDOH have a significant impact on the risk of CA, pre-arrest care patterns, and post-arrest mortality. Determining the impact that SDOH have on the CA care continuum provides can provide actionable targets to prevent CA and subsequent mortality.
