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

Area of Science:

• Health Services Research
• Chronic Disease Management
• Health Economics

Background:

• Case management is recognized as a cost-effective approach for coordinating patient care, particularly for individuals with chronic illnesses.
• Existing research on the impact of case management on healthcare utilization presents inconsistent findings.
• A comprehensive synthesis of evidence is needed to clarify the effectiveness of case management interventions.

Purpose of the Study:

• To systematically synthesize and critically evaluate evidence from systematic reviews on the healthcare utilization outcomes of case management interventions for chronic illnesses.
• To identify specific healthcare utilization metrics affected by case management, including hospital readmissions, emergency department visits, and overall healthcare access.
• To provide a consolidated understanding of the effectiveness of case management in managing chronic conditions.

Main Methods:

• A systematic review of systematic reviews was conducted, focusing on English-language publications from January 1990 to June 2017.
• Seven relevant systematic reviews were identified and their findings on healthcare utilization outcomes were synthesized.
• Key outcomes analyzed included hospital readmissions, length of hospital stay, institutionalization, emergency department visits, and hospital/primary care visits.

Main Results:

• Evidence suggests that case management interventions can positively reduce healthcare utilization among chronic illness patients.
• Specific outcomes such as hospital readmissions and emergency department visits showed potential reductions.
• However, the overall findings across the reviewed studies were mixed, indicating variability in intervention effectiveness.

Conclusions:

• Case management demonstrates potential for reducing healthcare utilization in chronic illness care, though results are not uniformly positive.
• The findings highlight the need for further research to identify optimal case management strategies and patient populations that benefit most.
• This review of reviews offers valuable insights for clinicians, researchers, and policymakers involved in chronic disease management and healthcare system design.
