Care for older adults with dementia: PACE day care or residential dementia care units?

Background: Persons with dementia (PwD) are at greater risk for various adverse health outcomes, and the best care model remains to be determined. This study aimed to compare the physical and neurocognitive performance of PwD in the Program of All-inclusive Care for the Elderly (PACE) and residential dementia care units. Methods: This was a case-control study comparing outcomes between care recipients of PACE services (PC group) and residential dementia care (RC group). Demographic characteristics, underlying diseases, physical function, cognitive function, mood status, and behavioral and psychotic symptoms of dementia (BPSDs) were assessed every 3-6 months in both groups, while frailty status and Timed Up-and-Go Test (TUGT) performance were assessed every 6 months in the PC group only. Results: Overall, 96 participants (PC group: 25, RC group: 71; mean age: 86.4 +/- 6.8 years) were enrolled with the median follow-up period of 43.6 weeks. Lower incidence of hospital admissions was noted in the PC group (0.52 +/- 1.12 vs 1.38 +/- 2.49 admissions/1,000 person-days, p=0.023), even though the PC group had higher multimorbidity and more severe BPSDs. During the study period, the PC group showed a significant improvement in body mass index, less physical dependence, better cognitive performance and reduced depressive mood. In addition, the PC group showed improvement in frailty, leisure hour activities, and TUGT results. However, participants in the PC group were more likely to experience BPSD deterioration (beta coeff.: 0.193, 95% CI: 0.1210.265). Conclusion: The PACE services significantly reduced unexpected hospital admissions of PwD, facilitated the maintenance of physical independence, and improved cognitive performance and mood status. Further randomized controlled studies are needed to determine the most appropriate care model for PwD.

Automated summary

This study compared the physical and neurocognitive performance of elderly dementia patients receiving PACE services with those in residential dementia care units. The results showed that PACE services significantly reduced hospital admissions, improved physical and cognitive function, and reduced depressive mood among dementia patients. Further randomized controlled studies are needed to determine the most appropriate care model for persons with dementia.
