Social Vulnerability Predictors of Acute Care: Leveraging Health Information Exchange Data to Understand Social Determinants at the Census Tract Level in a Correlational Study.
Article in Health science reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background and Aims: While geographic social vulnerability is a known predictor of acute care utilization, it is not known which specific vulnerabilities are the best predictors. This is particularly important in rural areas where there are significant disparities. The purpose of this study was to identify social vulnerability predictors of acute care utilization across and within rural counties in Hawai'i. Methods: This correlational study examined counts of emergency department (ED) visits and inpatient (IP) admissions for any reason by census tract obtained from Hawai'i Health Information Exchange for rural counties in Hawai'i. The overall Social Vulnerability Index (SVI), SVI subthemes, and individual measures that comprise the composites were used as measures of social vulnerability for each census tract. Regression models analyzed counts per population, after adjustments for missing data, where the response variable represents the number of events occurring. Each outcome (number of ED or IP visits) was regressed on a single predictor of social vulnerability for each county and for all counties combined. Results: Across counties, the largest significant effect associated with acute care utilization was overall social vulnerability (ED: IRR = 5.72, 95% CI = 5.55-5.89; IP: IRR = 5.76, 95% CI = 5.42-6.12). The largest effect within Kaua'i County was Racial and Ethnic Minority Status (ED: IRR = 5.38, 95% CI = 5.13-5.64; IP: IRR = 6.30, 95% CI = 5.64-7.03), within Maui County was Housing Type and Transportation (ED: IRR = 6.72, 95% CI = 6.37-7.1; IP: IRR = 4.46, 95% CI = 3.99-5), and within Hawai'i County was Household Characteristics for ED (IRR = 11.50, 95% CI = 10.91-12.12) and No High School Diploma for IP (IRR = 6.33, 95% CI = 5.79-6.93). Conclusions: Social vulnerability is a significant predictor of acute care utilization across rural areas in Hawai'i. The strongest predictors were different for each county.
