1 · What the graph read from it

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.

2 · The registry

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

purposeTo examine whether living in highly segregated communities or having comorbidity is associated with an increased risk of acute use of emergency and inpatient services (i.e., acute care utilization [ACU]) among racial minorities. METHODOLOGY: This longitudinal study included adult patients who underwent health-related social needs screening during their medical appointments within the Mass General Brigham healthcare system from March 2018 to January 2023. Our primary outcome was 180-day ACU defined as a composite outcome of all-cause emergency departments visits or hospital admissions following the most recent screening. Residential segregation was assessed using the index of dissimilarity, with a score of 0.6 or higher indicating extremely high segregation.

resultsAmong the 81,571 patients, 38% were non-White, and 28% were Hispanic. Approximately 18% lived in highly segregated communities and 55% had comorbidity. Accounting for demographic and clinical characteristics, Cox regression model found that living in highly segregated areas was generally not associated with the risk of 180-day ACU. Compared to White, non-White had a higher risk of ACU (HR = 1.07 [95%CI: 1.02 - 1.12]). Patients with comorbidity had a higher risk of ACU relative to their counterparts without comorbidity (HR = 1.65 [95%CI: 1.58 - 1.73]). Among patients in highly segregated areas, non-White experienced a 26% higher risk of ACU, compared with White in the same areas. However, for patients with comorbidity, non-White showed only a 5% higher risk of ACU relative to White.

conclusionsWe found an additive effect of residential segregation on racial disparities in ACU. Comorbidity is a risk factor of ACU for all patients.
