Health Influence and Association Analysis of Inpatient Service Under-Utilization in Older Adults With Multimorbidities: A National Study in China.
Article in Health care science, 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
Background: In the Chinese aging population characterized by rising chronic comorbidities, this study investigated under-utilization of inpatient services (hospitalization) among elderly individuals with multimorbidities, aiming to elucidate its health impacts and contributing factors so as to inform policy. Methods: A national household investigation was conducted using cross-sectional and prospective methods. The study included 3636 adults aged ≥ 60 with multimorbidities from the China Health and Retirement Longitudinal Study (CHARLS 2015), with follow-up health assessments in 2018. Cox regression was employed to analyze the health consequences of non-hospitalization; logistic regression analysis identified contributing factors. Results: Overall, 8.7% of elderly adults with multimorbidities declined hospitalization despite medical necessity. After adjusting for demographics and lifestyle factors, we found that this refusal was significantly linked to a deterioration in self-rated health (hazard ratio [HR]: 1.273; 95% confidence interval [CI]: 1.091-1.484) and inability to work normally (HR: 1.244; 95% CI: 1.060-1.459) and inability to perform normal household tasks (HR: 1.579; 95% CI: 1.250-1.996) after 3 years. In the fully adjusted model, non-hospitalization despite medical necessity remained a statistically significant risk factor for a decreased ability to perform normal household chores (HR: 1.403; 95% CI: 1.064-1.851), particularly affecting families with poor economic status (HR: 1.529; 95% CI: 1.003-2.332). Key independent factors for non-hospitalization despite medical needs included physical dysfunctions (odds ratio [OR]: 2.646; 95% CI: 1.644-4.260), inadequacy of long-term care (OR: 1.341; 95% CI: 1.006-1.787), being very dissatisfied with marriage (OR: 2.629; 95% CI: 1.137-6.079), and increased number of chronic multimorbidities (OR: 1.292; 95% CI: 1.190-1.402). Conclusions: Inadequate inpatient service utilization among multimorbid elderly individuals exacerbates health risks, particularly for those with physical limitations, marital distress, care deficits, and high chronic disease burdens. Therefore, targeted interventions are urgently required.
