BACKGROUND: We sought to determine the comparative effectiveness of two strategies for assigning care coordinators to people living with dementia (PLWD) and their caregivers. METHODS: We conducted a pragmatic randomized clinical trial embedded in a Medicare accountable care organization (ACO) in New York, NY in 2022-2024. We included community-dwelling PLWD ≥ 65 years who were attributed to the ACO and had highly fragmented ambulatory care in the previous year (reversed Bice-Boxerman Index ≥ 0.86). The trial compared usual care (assigning care coordinators to PLWD after hospital discharge) to usual care plus proactive outreach, which assigned care coordinators to PLWD if they or their caregivers reported difficulty with care coordination on a telephone survey. Participants were followed for the combined outcome of emergency department (ED) visit or hospitalization. RESULTS: Among the 385 PLWD in the trial, the mean age was 82.6 years (SD 6.9), and 56.4% were female. Overall, participants had had a mean of 14.9 ambulatory visits to 8.9 different providers the previous year. The acceptance rate of care management was higher in the control group (73.7%) than in the intervention group (38.0%). Care coordinators were ultimately assigned to 14 of 192 PLWD in the control group (7.3%) and 19 of 193 PLWD in the intervention group (9.8%). The intention-to-treat analysis (N = 385) found a trend toward fewer ED visits in the intervention group (0.14 ED visits per 100 person-days alive vs. 0.18 ED visits per 100 person-days alive, p = 0.07) but no difference in the combined outcome of ED visit or hospitalization (p = 0.71). CONCLUSION: Although the particular intervention we tested was not more effective than usual care, this trial is novel in that it used highly fragmented care as an inclusion criterion and shows that more work is needed to address fragmented care among PLWD.
