Assessing Health Care Use Trajectories After the Onset of Functional Disability: Application of a Group-Based Trajectory Model.
Article in The journals of gerontology. Series B, Psychological sciences and social sciences, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
objectivesWhile older adults with activity limitations have high levels of health care use, we do not know how this varies over time. We aimed to assess trajectories of Emergency Department (ED) use and hospitalization after the onset of receipt of help with self-care or mobility.
methodsWe used the 2011-2017 National Health Aging Trends Study (NHATS) linked to Medicare claims to identify a cohort of older adults who began to receive help with self-care or mobility in the past year. Primary outcome was the quarterly rates of ED use and/or hospitalization over the 24 months following the onset of receiving help. We fit a Group-Based Trajectory Model to identify the trajectories of ED use or hospitalization and assessed the association of characteristics preceding and concurrent to the onset of help with trajectory group membership.
resultsAmong 1,687 NHATS respondents newly receiving help with self-care/mobility, health care use escalated and then immediately fell. We found distinct trajectories of ED use and hospitalization: delayed rise (13.5%), falling (26.2%), and persistent (60.4%). Trajectory group membership was predicted by clinical, economic, and regional characteristics; and the individuals in each group differed in terms of concurrent new illnesses and degree of disability. DISCUSSION: While activity limitations are a strong predictor of health care use among older adults, trajectories of health care use are heterogeneous. Along with clinical characteristics, potentially modifiable household and regional factors shaped health care trajectories, indicating that addressing these factors could potentially shift health care use patterns.
