Background: All community-living older adults might benefit from integrated care, but evidence is lacking on the effectiveness of such services for perceived quality of care.
Objective: To examine the impact of Embrace, a community-based integrated primary care service, on perceived quality of care.
Design: Stratified randomized controlled trial.
Participants: Integrated care and support according to the "Embrace" model was provided by 15 general practitioners in the Netherlands. Based on self-reported levels of case complexity and frailty, a total of 1456 community-living older adults were stratified into non-disease-specific risk profiles ("Robust," "Frail," and "Complex care needs"), and randomized to Embrace or control groups.
Intervention: Embrace provides integrated, person-centered primary care and support to all older adults living in the community, with intensity of care dependent on risk profile.
Measurements: Primary outcome was quality of care as reported by older adults on the Patient Assessment of Integrated Elderly Care (PAIEC). Effects were assessed using mixed model techniques for the total sample and per risk profile. Professionals' perceived level of implementation of integrated care was evaluated within the Embrace condition using the Assessment of Integrated Elderly Care.
Key results: Older adults in the Embrace group reported a higher level of perceived quality of care than those in the control group (B = 0.33, 95 % CI = 0.15-0.51, ES d = 0.19). The advantages of Embrace were most evident in the "Frail" and "Complex care needs" risk profiles. We found no significant advantages for the "Robust" risk profile. Participating professionals reported a significant increase in the perceived level of implementation of integrated care (ES r = 0.71).
Conclusions: This study shows that providing a population-based integrated care service to community-living older adults improved the quality of care as perceived by older adults and participating professionals.
