Effectiveness and cost-effectiveness of integrated care models for elderly, complex patients: A narrative review. Don’t we need a value-based approach?

Introduction: The management of patients with complex health and social needs is one of the main challenges for healthcare systems. Integrated care seems to respond to this issue, with collaborative working and integration efforts of the care system components professionals and service providers aimed at improving efficiency, appropriateness and person centeredness of care. We conducted a narrative review to analyse the available evidences published on effectiveness and cost-effectiveness of integrated care models targeted on the management of such elderly patients. Methods: MEDLINE, Scopus and EBSCO were searched. We reported this narrative review according to the PRISMA Checklist. For studies to be included, they had to: (i) refer to integrated care models through implemented experimental or demonstration projects; (ii) focus on frail elderly ≥65 years old, with complex health and social needs, not disease-specific; (iii) evaluate effectiveness and/or cost and/or cost-effectiveness; (iv) report quantitative data (e.g. health outcomes, utilization outcomes, cost and cost-effectiveness). Results: Thirty articles were included, identifying 13 integrated care models. Common features were identified in case management, geriatric assessment and multidisciplinary team. Favourable impacts on healthcare facilities utilization rates, though with mixed results on costs, were found. The development of community-based and cost-effective integrated systems of care for the elderly is possible, thanks to the cooperation across care professionals and providers, to achieving a relevant impact on healthcare and efficient resource management. The elements of success or failure are not always unique and identifiable, but the potential clearly exists for these models to be successful and generalized on a large scale. Discussion: We found out a favourable impact of integrated care models/methods on health outcomes, care utilization and costs. The selected interventions are likely to be implemented at community level, focused on the patient management in terms of continuity of care. Thus, we propose a value-based framework for the evaluation of these services.
