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

backgroundReducing the 30-day hospital readmission rate is a national priority and patient activation has emerged as a modifiable target to reduce hospital readmissions.

objectivePrior studies demonstrate that low patient activation and low health literacy are each associated with higher rates of hospital utilization. The aim of this study was to use path analysis methods to assess if patient activation mediates the relationship between health literacy and hospital utilization in the 30 days after discharge. DESIGN AND

participantsWe performed a secondary analysis of data from a randomized controlled trial of patients receiving care at an urban safety net hospital. Path analyses were used to assess patient activation as a mediator of the relationship of education and health literacy with 30-day hospital utilization. The final model was stratified by race and ethnicity. MEASURE: 30 day Hospital Utilization.

resultsIn the overall study sample, a one standard deviation (SD) higher patient activation measure (PAM) score was associated with 18% reduced odds of hospital utilization (odds ratio (OR) 0.82, 95% confidence interval (CI): 0.73, 0.91, p=<0.001). PAM mediated the relationship between education level and health literacy and hospital utilization. When stratified by race, the mediating effect of PAM was evident among Whites, but not among non-Whites. Specifically, a one SD higher PAM score was significantly associated with a 33% reduced odds of utilization among Whites (OR 0.67, 95% CI: 0.57, 0.79, p<0.001). With the inclusion of PAM in the model, there was no direct relationship between either health literacy or education and 30-day hospital utilization.

conclusionPatient activation is only associated with hospital utilization among Whites. Further research is needed to assess if this selective protection is seen in other cohorts. Potential interventions to reduce hospital readmissions may need to consider other modifiable factors in racially and ethnically diverse populations.
