Economic Impact of Integrated Care Models for Patients with Chronic Diseases: A Systematic Review.

OBJECTIVES: To assess the costs and potential financial benefits of integrated care models for patients with chronic diseases, that is, type 2 diabetes mellitus, schizophrenia, and multiple sclerosis, respectively.

METHODS: A systematic search of the literature was performed using EMBASE, MEDLINE, and Web of Science. Studies that conducted a cost analysis, considered at least two components of the chronic care model, and compared integrated care with standard care were included.

RESULTS: Out of 575 articles, 26 were included. Most studies examined integrated care models for type 2 diabetes mellitus (n = 18) and to a lesser extent for schizophrenia (n = 6) and multiple sclerosis (n = 2). Across the three disease groups, the incremental cost per patient per year ranged from - €3860 to + €613.91 (x¯ = - €533.61 ± €902.96). The incremental cost for type 2 diabetes mellitus ranged from - €1507.49 to + €299.20 (x¯ = - €518.22 ± + €604.75), for schizophrenia from - €3860 to + €613.91 (x¯ = - €677.21 ± + €1624.35), and for multiple sclerosis from - €822 to + €339.43 (x¯ = - €241.29 ± + €821.26). Most of the studies (22 of 26 [84.6%]) reported a positive economic impact of integrated care models: for type 2 diabetes mellitus (16 of 18 [88.9%]), schizophrenia (4 of 6 [66.7%]), and multiple sclerosis (1 of 2 [50%]).

CONCLUSIONS: In this systematic literature review, predominantly positive economic impacts of integrated care models for patients with chronic diseases were found.
