Case Management Effectiveness on Health Care Utilization Outcomes: A Systematic Review of Reviews.

Case management is a cost-effective strategy for coordinating chronic illness care. However, research showing how case management affects health care is mixed. This study systematically synthesizes and critically evaluates evidence in systematic reviews of health care utilization outcomes from case management interventions for the care of chronic illnesses. Results are synthesized from seven English language systematic reviews published between January 1990 and June 2017. Hospital readmissions, length of hospital stay, institutionalization, emergency department visits, and hospitals/primary care visits were all identified as health care utilization outcomes of case management interventions. There was evidence that these interventions positively reduced health care utilization; however, results were mixed. These results and the implications of this review of reviews may be valuable for clinical practitioners, health care researchers, and policymakers.
