Utilization Patterns Among Heterogeneous Subgroups of Homebound Older Adults: A Latent Class Analysis.
Observational study in Journal of the American Geriatrics Society, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundHomebound older adults represent a high-risk, high-needs population characterized by significant clinical and sociodemographic heterogeneity. Little is known about how such heterogeneity shapes care needs and utilization patterns. We characterized utilization patterns among distinct subgroups of homebound older adults and examined associations between levels of outpatient care and emergency department (ED) utilization. PARTICIPANTS AND
settingWe used nationally representative data from the National Health and Aging Trends Study (NHATS) linked to Medicare Fee-For-Service (FFS) claims from 2011 to 2019 and 2021-2023 to examine trends among homebound older adults ages 70 or older.
methodsIn this retrospective observational study, we characterized utilization patterns among distinct subgroups of homebound older adults identified using latent class analysis (LCA). We then used multivariable regression to examine associations between level of outpatient utilization and probability of both any ED visit and any potentially avoidable ED visit identified using Ambulatory Care Sensitive Conditions (ACSC). We adjusted for other indicators of ED use and access to care (i.e., self-reported health, rurality, and disease burden).
resultsThere was a total of 2202 person-year observations across 1343 unique homebound individuals. The LCA identified four subgroups of homebound older adults: functional independence; dementia; multimorbidity; and dementia plus multimorbidity. There were significant differences in levels of ambulatory and acute care utilization between subgroups. Regression analyses did not show evidence to support the conventional wisdom that inability to access ambulatory care leads to more avoidable ED visits among the homebound older adult population.
conclusionsHeterogeneity among the homebound older adult population shapes care needs that in turn influence utilization patterns. Understanding these dynamics is crucial to targeting interventions like home-based primary care to the highest risk groups while tailoring care to individual needs.
