An epidemiologic perspective on a case management program.

Area of Science:

• Epidemiology
• Health Services Research
• Healthcare Management

Background:

• Case management (CM) programs aim to improve patient outcomes and healthcare efficiency.
• Epidemiological principles offer tools for program evaluation and optimization.
• Understanding the relationship between CM interventions and patient outcomes is crucial for resource allocation.

Purpose of the Study:

• To enhance a case management (CM) program using epidemiological methods.
• To analyze factors influencing patient outcomes within a CM program.
• To assess the effectiveness of CM interventions and guide resource allocation for improved efficiency.

Main Methods:

• Utilized epidemiological principles to analyze a CM program within a Medicare Advantage health plan.
• Described the managed population (N=12,185) and analyzed the relationship between CM 'dose' and patient risk profiles.
• Compared pre-CM and post-CM costs to estimate program impact, acknowledging potential biases like regression to the mean.

Main Results:

• A linear relationship was observed between the 'dose' of CM (contact frequency) and patient risk profiles.
• Average healthcare costs were lower in the 6 months post-CM compared to the 6 months pre-CM.
• The greatest value was observed in managing moderate-risk cases with 2-4 CM contacts, though regression to the mean may influence findings.

Conclusions:

• CM resource allocation appeared aligned with patient risk, indicating resources were directed to those in need.
• Population-based epidemiological assessments can improve the efficiency of CM resource allocation.
• Future studies should incorporate control groups to establish comparative effectiveness of CM interventions.
