Economic effectiveness of disease management programs: a meta-analysis

Area of Science:

• Health Economics
• Chronic Disease Management

Background:

• Disease management programs aim to improve clinical and economic outcomes for chronically ill individuals.
• Extensive evaluation of these programs' economic effectiveness has been conducted.

Purpose of the Study:

• To perform a meta-analysis on the direct economic outcomes of disease management programs for asthma, diabetes, and heart disease.
• To determine the overall economic effectiveness of these interventions.

Main Methods:

• A literature search was conducted using MEDLINE and other sources from January 1995 to September 2003.
• Included were empirical articles measuring direct economic outcomes for asthma, diabetes, and heart disease management programs.
• A meta-analysis was performed on 67 selected articles (32,041 subjects).

Main Results:

• The meta-analysis revealed a statistically significant positive effect size (0.311) for disease management programs.
• No significant differences in effect sizes were found based on study design, disease type, or intervention intensity.
• Disease severity was identified as a key moderating variable.

Conclusions:

• Disease management programs are economically effective, particularly for severely ill enrollees.
• Chronic disease interventions are most effective when tailored to disease severity.
• Findings support healthcare policymakers and practitioners in providing cost-effective chronic care.
