A large-scale study evaluating different approaches to dementia care has found no significant differences in patient behavioral symptoms or caregiver strain, regardless of whether the care was provided through a health system, a community-based organization, or standard medical care. However, the study did reveal that caregivers who received structured support—either from a health system or a community-based organization—reported greater confidence in managing dementia-related challenges.
Understanding the Dementia-CARE Study
Known as the Dementia Care Study (D-CARE), the research was led by experts at the University of California, Los Angeles (UCLA) and is set to be published in the Journal of the American Medical Association (JAMA) on January 29. The study, conducted from June 2019 to August 2023, included 2,176 individuals with it and their caregivers. Participants were randomly assigned to one of three groups:
- A health system-based program featuring Dementia Care Specialists following the UCLA Alzheimer’s and Dementia Care Program model
- A community-based program where Care Consultants utilized the Benjamin Rose Institute on Aging Care Consultation Program
- Usual care, with no additional structured its care support
Despite expectations that more specialized care approaches would improve patient and caregiver outcomes, the study found no significant reduction in caregiver strain or patient behavioral symptoms across the different models over an 18-month period.
Caregivers Report Higher Confidence in Specialized Programs
While the study did not find significant differences in patient outcomes, it did reveal an essential benefit for caregivers. Those in the health system and community-based programs reported higher self-efficacy, meaning they felt more confident in managing caregiving challenges and accessing support services. This boost in confidence appeared within the first six months and remained stable throughout the study.
Dr. David Reuben, the study’s principal investigator and a professor of geriatrics at UCLA, emphasized the significance of this finding. “Caregivers play an essential role in the lives of individuals with dementia, and their ability to manage stress and feel confident in their caregiving roles is crucial. Higher self-efficacy may lead to obtaining more resources and keeping persons with it in their homes.”
Implications for Healthcare Systems and Policy
The results of the D-CARE study hold important implications for healthcare providers, community organizations, policymakers, and insurers working to improve dementia care. While structured dementia care programs may not necessarily reduce caregiver strain or improve patient symptoms more effectively than usual care, they provide caregivers with the tools and confidence needed to navigate the complexities of dementia care.
Reuben also noted the challenges of evaluating dementia care models in real-world settings, particularly during the disruptions caused by the COVID-19 pandemic. “Some benefits of the models may not have been fully captured in the trial’s chosen primary and secondary outcomes,” he said. Further analysis of the study’s data, particularly regarding healthcare utilization, is ongoing.
The findings also have potential relevance for institutions participating in Medicare’s new Guiding an Improved Dementia Experience (GUIDE) program, which aims to enhance support for dementia patients and their caregivers.
The Patient-Centered Outcomes Research Institute and the National Institute on Aging funded the D-CARE study, with additional support from multiple research centers and healthcare institutions. The full results and further analysis are expected to shape future discussions on the most effective ways to support its patients and their caregivers.
