Optimization of the multimorbidity management model for older adults: a study on the mediating effect of health literacy on self-efficacy and health status.
Article in BMC geriatrics, 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
backgroundThe prevalence of chronic diseases and chronic comorbidities among the older adults is increasing annually with the advent of an aging population, making health management for older patients with chronic conditions essential. However, optimizing management models requires mobilizing the patients' own agency. Individual capacity, specifically self-efficacy and health literacy, plays a pivotal role in this process. Therefore, this study aims to analyze the relationship between self-efficacy, health literacy, and health status among older patients with comorbidities, and further explore the potential pathways by which self-efficacy and health literacy are associated with health status. The goal is to provide a scientific basis for informing the refinement of comorbidity management models for older adults and supporting better health status of patients.
methodsAdopting a multistage stratified cluster random sampling method, older patients with multimorbidity in communities of Shenzhen, Guangdong Province were selected as the survey subjects. Using the "Health Survey Questionnaire for older patients with multimorbidity" for face-to-face interviews, 1200 older adults were surveyed, and 987 valid patient data were selected. Descriptive analysis was conducted on the self-efficacy, health literacy, and health status of older patients with multimorbidity in Shenzhen, Guangdong Province. A structural equation model was constructed to analyze the mediating effect of health literacy between self-efficacy and health status.
resultsIn the survey of 987 older patients with multimorbidity in this study, the average score for self-efficacy was 8.07 ± 1.36, indicating a high level on average; the average score for health literacy was 32.16 ± 9.39, suggesting a possible inadequacy in health literacy level; and the average score for health status was 73.60 ± 19.70. The well-fitted structural equation model results demonstrate that self-efficacy (β = 0.148, P < 0.001) and health literacy (β = 0.317, P < 0.001) of older patients with multimorbidity are positively associated with health status. Specifically, the mediating effect of health literacy on the relationship between self-efficacy and health status accounts for 38.1% of the total effect (Effect size = 0.042, 95% CI: 0.022-0.069), serving as a partial mediator with a significant mediating effect.
conclusionsIn the multimorbidity management model for older adults, interventions such as patient peer support groups and case manager-led health education are proposed as theoretical strategies. These potential measures aim to support patient self-efficacy and facilitate health literacy, thereby potentially contributing to better overall health of patients.
