Patient and Caregiver Benefit From a Comprehensive Dementia Care Program: 1‐Year Results From the UCLA Alzheimer's and Dementia Care Program

摘要

BACKGROUND/OBJECTIVES Persons with Alzheimer disease and related dementias (ADRDs) require comprehensive care that spans health systems and community‐based organizations. This study examined the clinical outcomes of a comprehensive dementia care program and identified subgroups who were more likely to benefit. DESIGN Observational, baseline and 1 year after intervention. SETTING Urban, academic medical center. PARTICIPANTS A total of 554 persons with dementia and their caregivers who had 1‐year follow‐up evaluations and data on clinical outcomes. INTERVENTION Health system‐based comprehensive dementia care management program using nurse practitioner dementia care managers. MEASUREMENTS Patient measures included the Mini‐Mental State Examination (MMSE), the Functional Activities Questionnaire, Basic and Instrumental Activities of Daily Living scales, the Cornell Scale for Depression in Dementia, and the Neuropsychiatric Inventory Questionnaire (NPI‐Q) Severity. Caregiver measures included the Modified Caregiver Strain Index, the Patient Health Questionnaire‐9, NPI‐Q Distress, and the Dementia Burden Scale‐Caregiver). We used established minimal clinically important differences and lowest tertiles of baseline symptoms to define improving symptoms and maintaining low symptoms as clinical benefit for patients and caregivers. RESULTS At year 1, persons with ADRD improved on all scales, except MMSE and functional status measures; caregivers improved on all scales. Using validated instruments, 314/543 (58%) of patients, 282/447 (63%) of caregivers, and 376/501 (75%) of patients or caregivers demonstrated clinical benefit. In adjusted multivariate models, at year 1, more behavioral symptoms and fewer depression symptoms at baseline were associated with patient improvement; and fewer baseline depression symptoms were associated with maintaining low behavioral symptoms. Male caregiver sex, higher baseline caregiver burden, and caring for patients with fewer baseline depression symptoms were associated with caregiver improvement. Male caregiver sex and patients with fewer depression symptoms, fewer behavioral symptoms, and more functional impairment at baseline were associated with caregivers maintaining low burden at 1 year. CONCLUSIONS Health system‐based comprehensive dementia care management is a promising approach to improving clinical outcomes, with benefits for both patients and caregivers.
