Abstract

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 ( = − €533.61 ± €902.96). The incremental cost for type 2 diabetes mellitus ranged from − €1507.49 to + €299.20 ( = − €518.22 ± + €604.75), for schizophrenia from − €3860 to + €613.91 ( = − €677.21 ± + €1624.35), and for multiple sclerosis from − €822 to + €339.43 ( = − €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.
