Gaps in the coordination of care for people living with dementia.

Abstract

Background: One-third of people living with dementia (PLWD) have highly fragmented care (i.e., care spread across many ambulatory providers without a dominant provider). It is unclear whether PLWD with fragmented care and their caregivers perceive gaps in communication among the providers involved and whether any such gaps are perceived as benign inconveniences or as clinically meaningful, leading to adverse events. We sought to determine the frequency of perceived gaps in communication (coordination) among providers and the frequency of self-reported adverse events attributed to poor coordination.

Methods: We conducted a cross-sectional study in the context of a Medicare accountable care organization (ACO) in New York in 2022-2023. We included PLWD who were attributed to the ACO, had fragmented care in the past year by claims (reversed Bice-Boxerman Index ≥0.86), and were in a pragmatic clinical trial on care management. We used an existing survey instrument to determine perceptions of care coordination and perceptions of four adverse events (repeat tests, drug-drug interactions, emergency department visits, and hospital admissions). ACO care managers collected data by telephone, using clinical judgment to determine whether each survey respondent was the patient or a caregiver. We used descriptive statistics to summarize results.

Results: Of 167 eligible PLWD, surveys were completed for 97 (58.1%). Of those, 88 (90.7%) reported having >1 ambulatory visit and >1 ambulatory provider and were thus at risk for gaps in care coordination and included in the analysis. Of those, 23 respondents were patients (26.1%) and 64 were caregivers (72.7%), with one respondent's role missing. Overall, 57% of respondents reported a problem (or "gap") in the coordination of care and, separately, 18% reported an adverse event that they attributed to poor care coordination.

Conclusion: Gaps in coordination of care for PLWD are reported to be very common and often perceived as hazardous.
