Caring for patients with dementia: how good is the quality of care? Results from three health systems.

OBJECTIVES: To describe the quality of dementia care within one U.S. metropolitan area and to investigate associations between variations in quality and patient, caregiver, and health system characteristics. DESIGN: Observational, cross-sectional. SETTING AND PARTICIPANTS: Three hundred eighty-seven patient-caregiver pairs from three healthcare organizations MEASUREMENTS: Using caregiver surveys and medical record abstraction to assess 18 dementia care processes drawn from existing guidelines, the proportion adherent to each care process was calculated, as well as mean percentages of adherence aggregated within four care dimensions: assessment (6 processes), treatment (6 processes), education and support (3 processes), and safety (3 processes). For each dimension, associations between adherence and patient, caregiver, and health system characteristics were investigated using multivariable models. RESULTS: Adherence ranged from 9% to 79% for the 18 individual care processes; 11 processes had less than 40% adherence. Mean percentage adherence across the four care dimensions was 37% for assessment, 33% for treatment, 52% for education and support, and 21% for safety. Higher comorbidity was associated with greater adherence across all four dimensions, whereas greater caregiver knowledge (in particular, one item) was associated with higher care quality in three of four care dimensions. For selected dimensions, greater adherence was also associated with greater dementia severity and with more geriatrics or neurologist visits. CONCLUSION: In general, dementia care quality has considerable room for improvement. Although greater comorbidity and dementia severity were associated with better quality, caregiver knowledge was the most consistent caregiver characteristic associated with better adherence. These findings offer opportunities for targeting low quality and suggest potential focused interventions.

The effect of a disease management intervention on quality and outcomes of dementia care: a randomized, controlled trial.

BACKGROUND: Adherence to dementia guidelines is poor despite evidence that some guideline recommendations can improve symptoms and delay institutionalization of patients. OBJECTIVE: To test the effectiveness of a dementia guideline-based disease management program on quality of care and outcomes for patients with dementia. DESIGN: Clinic-level, cluster randomized, controlled trial. SETTING: 3 health care organizations collaborating with 3 community agencies in southern California. PARTICIPANTS: 18 primary care clinics and 408 patients with dementia age 65 years or older paired with 408 informal caregivers. INTERVENTION: Disease management program led by care managers and provided to 238 patient-caregiver pairs at 9 intervention clinics for more than 12 months. MEASUREMENTS: Adherence to 23 guideline recommendations (primary outcome) and receipt of community resources and patient and caregiver health and quality-of-care measures (secondary outcomes). RESULTS: The mean percentage of per-patient guideline recommendations to which care was adherent was significantly higher in the intervention group than in the usual care group (63.9% vs. 32.9%, respectively; adjusted difference, 30.1% [95% CI, 25.2% to 34.9%]; P < 0.001). Participants who received the intervention had higher care quality on 21 of 23 guidelines (P < or = 0.013 for all), and higher proportions received community agency assistance (P < or = 0.03) than those who received usual care. Patient health-related quality of life, overall quality of patient care, caregiving quality, social support, and level of unmet caregiving assistance needs were better for participants in the intervention group than for those in the usual care group (P < 0.05 for all). Caregiver health-related quality of life did not differ between the 2 groups. LIMITATIONS: Participants were well-educated, were predominantly white, had a usual source of care, and were not institutionalized. Generalizability to other patients and geographic regions is unknown. Also, costs of a care management program under fee-for-service reimbursement may impede adoption. CONCLUSIONS: A dementia guideline-based disease management program led to substantial improvements in quality of care for patients with dementia. Current Controlled Trials identifier: ISRCTN72577751.
