Care Ecosystem Collaborative Model and Health Care Costs in Medicare Beneficiaries With Dementia: A Secondary Analysis of a Randomized Clinical Trial.

Importance: Collaborative dementia care programs are effective in addressing the needs of patients with dementia and their caregivers. However, attempts to consider effects on health care spending have been limited, leaving a critical gap in the conversation around value-based dementia care. Objective: To determine the effect of participation in collaborative dementia care on total Medicare reimbursement costs compared with usual care. Design, Setting, and Participants: This was a prespecified secondary analysis of the Care Ecosystem trial, a 12-month, single-blind, parallel-group randomized clinical trial conducted from March 2015 to March 2018 at 2 academic medical centers in California and Nebraska. Participants were patients with dementia who were living in the community, aged 45 years or older, and had a primary caregiver and Medicare fee-for-service coverage for the duration of the trial. Intervention: Telehealth dementia care program that entailed assignment to an unlicensed dementia care guide who provided caregiver support, standardized education, and connection to licensed dementia care specialists. Main Outcomes and Measures: Primary outcome was the sum of all Medicare claim payments during study enrollment, excluding Part D (drugs). Results: Of the 780 patients in the Care Ecosystem trial, 460 (59.0%) were eligible for and included in this analysis. Patients had a median (IQR) age of 78 (72-84) years, and 256 (55.7%) identified as female. Participation in collaborative dementia care reduced the total cost of care by $3290 from 1 to 6 months postenrollment (95% CI, -$6149 to -$431; P = .02) and by $3027 from 7 to 12 months postenrollment (95% CI, -$5899 to -$154; P = .04), corresponding overall to a mean monthly cost reduction of $526 across 12 months. An evaluation of baseline predictors of greater cost reduction identified trends for recent emergency department visit (-$5944; 95% CI, -$10 336 to -$1553; interaction P = .07) and caregiver depression (-$6556; 95% CI, -$11 059 to -$2052; interaction P = .05). Conclusions and Relevance: In this secondary analysis of a randomized clinical trial among Medicare beneficiaries with dementia, the Care Ecosystem model was associated with lower total cost of care compared with usual care. Collaborative dementia care programs are a cost-effective, high-value model for dementia care. Trial Registration: ClinicalTrials.gov Identifier: NCT02213458.

Effect of collaborative dementia care on potentially inappropriate medication use: Outcomes from the Care Ecosystem randomized clinical trial.

INTRODUCTION: Potentially inappropriate medications (PIMs) cause adverse events and death. We evaluate the Care Ecosystem (CE) collaborative dementia care program on medication use among community-dwelling persons living with dementia (PLWD). METHODS: Secondary analysis of a randomized clinical trial (RCT) comparing CE to usual care (UC) on changes in PIMs, over 12 months between March 2015 and May 2020. Secondary outcomes included change in number of medications, clinically relevant PIMs, and anti-dementia medications. RESULTS: Of 804 PLWD, N = 490 had complete medication data. The CE resulted in significantly fewer PIMs compared to UC (-0.35; 95% CI, -0.49 to -0.20; P < 0.0001). Number needed to prevent an increase in 1 PIM was 3. Total medications, PIMs for dementia or cognitive impairment, CNS-active PIMs, anticholinergics, benzodiazepines, and opioids were also fewer. Anti-dementia medication regimens were modified more frequently. CONCLUSION: The CE medication review intervention embedded in collaborative dementia care optimized medication use among PLWD. HIGHLIGHTS: Compared to usual care (UC), the Care Ecosystem (CE) medication review intervention prevented increases in potentially inappropriate medications (PIMs). Use of anticholinergics, benzodiazepines, and opioids were significantly reduced, with a trend for antipsychotics. Anti-dementia medications were adjusted more frequently. The CE medication review intervention embedded in collaborative dementia care optimized medication use.

The Care Ecosystem: Promoting self-efficacy among dementia family caregivers.

OBJECTIVES: To illustrate specific psychosocial interventions aimed at improving self-efficacy among family caregivers enrolled in the Care Ecosystem, a model of navigated care designed to support persons with dementia and their primary caregivers. Enrolled family caregivers work with unlicensed care team navigators who are trained in dementia care and provide information, linkages to community resources, and emotional support by phone and email. METHOD: We conducted focus groups and interviews with the care team navigators to identify the approaches they used to target caregiver self-efficacy. We assessed mean self-efficacy scores in a sample of 780 family caregivers and selected three exemplary cases in which the caregivers had low self-efficacy scores at baseline with significantly higher scores after six months of participation in the Care Ecosystem intervention. RESULTS: Multiple psychosocial strategies were utilized by care team navigators working with patients with dementia and their family caregivers. Using thematic coding we identified three categories of Care Team Navigator intervention: emotional, informational, and instrumental support. These are consistent with a psychosocial approach to building self-efficacy. DISCUSSION: Self-efficacy represents a family caregiver's knowledge and preparedness in managing the challenges of care. Psychosocial support shows benefit in improving caregiver self-efficacy that in turn, may positively influence caregiver health and well-being. The findings in this manuscript demonstrate how a model of navigated care can positively impact self-efficacy among dementia family caregivers.

Effect of Collaborative Dementia Care via Telephone and Internet on Quality of Life, Caregiver Well-being, and Health Care Use: The Care Ecosystem Randomized Clinical Trial.

Importance: Few health systems have adopted effective dementia care management programs. The Care Ecosystem is a model for delivering care from centralized hubs across broad geographic areas to caregivers and persons with dementia (PWDs) independently of their health system affiliations. Objective: To determine whether the Care Ecosystem is effective in improving outcomes important to PWDs, their caregivers, and payers beyond those achieved with usual care. Design, Setting, and Participants: A single-blind, randomized clinical trial with a pragmatic design was conducted among PWDs and their caregivers. Each PWD-caregiver dyad was enrolled for 12 months between March 20, 2015, and February 28, 2017. Data were collected until March 5, 2018. Study interventions and assessments were administered over the telephone and internet by clinical and research teams in San Francisco, California, and Omaha, Nebraska. Of 2585 referred or volunteer PWD-caregiver dyads in California, Iowa, or Nebraska, 780 met eligibility criteria and were enrolled. A total of 512 PWD-caregiver dyads were randomized to receive care through the Care Ecosystem and 268 dyads to receive usual care. All eligible PWDs had a dementia diagnosis; were enrolled or eligible for enrollment in Medicare or Medicaid; and spoke English, Spanish, or Cantonese. Analyses were intention-to-treat. Intervention: Telephone-based collaborative dementia care was delivered by a trained care team navigator, who provided education, support and care coordination with a team of dementia specialists (advanced practice nurse, social worker, and pharmacist). Main Outcomes and Measures: Primary outcome measure: Quality of Life in Alzheimer's Disease based on caregiver's rating of 13 aspects of PWD's well-being (including physical health, energy level, mood, living situation, memory, relationships, and finances) on a 4-point scale (poor to excellent). Secondary outcomes: frequencies of PWDs' use of emergency department, hospitalization, and ambulance services; caregiver depression (score on 9-Item Patient Health Questionnaire; higher scores indicate more severe depression); and caregiver burden (score on 12-Item Zarit Burden Interview; higher scores indicate more severe caregiver burden). Results: The 780 PWDs (56.3% female; mean [SD] age, 78.1 [9.9] years) and 780 caregivers (70.9% female; mean [SD] age, 64.7 [12.0] years) lived in California (n = 452), Nebraska (n = 284), or Iowa (n = 44). Of 780 dyads, 655 were still active at 12 months, and 571 completed the 12-month survey. Compared with usual care, the Care Ecosystem improved PWD quality of life (B, 0.53; 95% CI, 0.25-1.30; P = .04), reduced emergency department visits (B, -0.14; 95% CI, -0.29 to -0.01; P = .04), and decreased caregiver depression (B, -1.14; 95% CI, -2.15 to -0.13; P = .03) and caregiver burden (B, -1.90; 95% CI, -3.89 to -0.08; P = .046). Conclusions and Relevance: Effective care management for dementia can be delivered from centralized hubs to supplement usual care and mitigate the growing societal and economic burdens of dementia.

Association Between Caregiver Depression and Emergency Department Use Among Patients With Dementia.

IMPORTANCE: Current attempts to gauge the acute care needs of patients with dementia have not effectively addressed the role of caregivers, despite their extensive involvement in decisions about acute care management. OBJECTIVE: To determine whether caregiver depression is associated with increased use of the emergency department (ED) among patients with dementia. DESIGN, SETTING, AND PARTICIPANTS: This longitudinal cohort study used data from the Care Ecosystem study, a randomized clinical trial examining telephone-based supportive care for patients with dementia and their caregivers. Patients were 45 years or older with any type of dementia. A total of 780 caregiver-patient dyads were enrolled from March 20, 2015, until February 28, 2017, and 663 dyads contributed baseline and 6-month data and were included in the analysis. EXPOSURES: Caregiver depression (9-item Patient Health Questionnaire score of ≥10). Secondary analyses examined caregiver burden and self-efficacy. MAIN OUTCOMES AND MEASURES: The primary outcome was the number of ED visits in a 6-month period. RESULTS: Among the 663 caregivers (467 women and 196 men; mean [SD] age, 64.9 [11.8] years), 84 caregivers (12.7%) had depression at baseline. The mean incidence rate of ED visits was 0.9 per person-year. Rates of ED presentation were higher among dyads whose caregiver did vs did not have depression (1.5 vs 0.8 ED visits per person-year). In a Poisson regression model adjusting for patient age, sex, severity of dementia, number of comorbidities, and baseline ED use, as well as caregiver age and sex, caregiver depression continued to be associated with ED use, with a 73% increase in rates of ED use among dyads with caregivers with depression (adjusted incident rate ratio, 1.73; 95% CI, 1.30-2.30). Caregiver burden was associated with higher ED use in the unadjusted model, but this association did not reach statistical significance after adjustment (incident rate ratio, 1.19; 95% CI, 0.93-1.52). Caregiver self-efficacy was inversely proportional to the number of ED visits in the unadjusted and adjusted models (adjusted incident rate ratio, 0.96; 95% CI, 0.92-0.99). CONCLUSIONS AND RELEVANCE: Among patients with dementia, caregiver depression appears to be significantly associated with increased ED use, revealing a key caregiver vulnerability, which, if addressed with patient- and caregiver-centered dementia care, could improve health outcomes and lower costs for this high-risk population.
