A clinimetric evaluation of specialized Geriatric care for rural dwelling, frail older people

OBJECTIVE: To test Comprehensive Geriatric Assessment (CGA) as an adjunct to usual care. DESIGN: A randomized controlled trial with 3, 6, and 12 months follow-up. SETTING: Rural communities. PATIENTS: A total of 182 of 265 frail older patients (52 refused, 2 withdrawn, 27 ineligible, 2 deaths) referred by family practitioners with allocation to intervention (n = 95) or usual care (n = 87). INTERVENTION: Three-month implementation of CGA recommendations by a Mobile Geriatric Assessment Team (MGAT) with follow-up assessments at 3, 6, and 12 months. Geriatric nurse assessors, blinded to group assignment, performed each assessment. MAIN OUTCOME MEASURE: Goal Attainment Scaling (GAS). RESULTS: Baseline characteristics were comparable between groups. At 3 months, the intervention group was more likely to attain their goals (GAS total: x̄ = 46.4 ± 5.9; GAS outcome x̄ = 48.0 ± 6.6) compared with controls (total: x̄ = 38.7 ± 4.1; outcome x̄ = 40.8 ± 5.6) (P < .001). Standard assessments of function (Barthel index, instrumental activities of daily living), cognition (Mini-Mental State Examination), and quality of life (modified Spitzer quality of life index) showed no difference over 12 months. No difference in survival (intervention: x̄ = 320 days, SE = 6; control: x̄ = 294 days, SE = 6; P = .257) or time to institutionalization (intervention: 340 days, SE = 9; control: 342 days, SE = 8; log rank = 0.661; P = .416) were observed. CONCLUSIONS: A MGAT can target rural dwelling, frail older persons, perform in-home CGA, and develop an intervention strategy. Although the intervention did not prolong life or delay institutionalization, clinically important benefits were observed.
