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

backgroundStudies have identified higher risk of readmission for patients with Medicaid compared to those with private insurance. Postdischarge follow-up is utilized as an intervention to reduce readmissions in the Medicare population, but it is unclear whether follow-up reduces risk of readmission for patients with Medicaid.

objectiveTo assess whether follow-up within 30 days of discharge reduces risk of readmission and mitigates readmission disparities based upon insurance status.

methodsThis retrospective cohort study used Cox proportional hazard and competing risk models to estimate associations between sociodemographic and clinical characteristics, follow-up, and readmission. We analyzed data from 4281 patients aged 21-64 years with Medicaid or private insurance who were hospitalized from January 2017 to December 2019 for one of five conditions associated with high risk of readmission. Outpatient follow-up within 30 days of discharge and 30-day all-cause readmission were outcomes.

resultsOverall risk of readmission was similar for Medicaid and privately insured patients in this cohort (13.7% and 14.5%, respectively). Patients with Medicaid were 23% points less likely to complete outpatient follow-up within 30 days compared to patients with private insurance (p < .001). However, outpatient follow-up before readmission within 30 days of discharge was not associated with a significant difference in readmission rate (hazard ratio: 1.10, 95% confidence interval: 0.91-1.32) in the overall sample or in analysis stratified by payer.

conclusionsWe found similar rates of readmission for Medicaid and privately insured patients despite significant disparities in postdischarge follow-up. Timely follow-up care alone may not be sufficient as an intervention to reduce readmissions.
