Effect of Community Health Workers on 30-Day Hospital Readmission: A Meta-analysis.
Synthesis in Journal of general internal 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
backgroundDespite the growing evidence that community health worker (CHW) interventions can mitigate social challenges and improve clinical outcomes in socially marginalized groups, little is known about their impact on 30-day hospital readmission rates. As such, this meta-analysis aims to evaluate the effectiveness of CHW interventions compared to usual care in reducing 30-day hospital readmission rates.
methodsA literature search was performed using PubMed and Embase. We used a random-effects model to calculate the pooled OR with 95% confidence intervals for the impact of CHW intervention on 30-day hospital readmission rates. Heterogeneity among studies was assessed using the I
resultsOf 235 retrieved studies, seven were eligible for inclusion, consisting of three randomized controlled trials (RCTS) and four observational studies (OBS). The pooled analysis demonstrated a significant reduction in 30-day hospital readmission rates among patients receiving CHW intervention compared to usual care (pooled log odds ratio 0.41, 95% CI = -0.74 to -0.07, p = 0.02). Subgroup analysis restricted to RCTs alone demonstrated no significant reduction in the 30-day readmission rates among patients receiving CHW interventions; however, there was a significant reduction when evaluating only OBS. Overall, this meta-analysis revealed moderate heterogeneity (I DISCUSSION: Overall, our pooled analysis supports the effectiveness of CHW interventions in reducing 30-day hospital readmission rates for socially marginalized patients; however, we found moderate heterogeneity due to differences in study design. As such, additional research is needed to confirm these findings. If validated, CHW interventions could be essential to reducing healthcare costs for socially marginalized patient populations.
