Evaluation of four disease management programs: evidence from blue cross blue shield of Louisiana
Insights
New disease management (DM) programs for chronic conditions like diabetes and heart disease proved cost-effective. These programs helped stabilize healthcare costs and showed potential for improved clinical outcomes in patients.
Area of Science:
- Health Economics
- Chronic Disease Management
- Clinical Outcomes Research
Background:
- Chronic diseases represent a significant financial and clinical burden on healthcare systems.
- Effective disease management (DM) strategies are crucial for mitigating this impact.
- This study focuses on DM programs for diabetes, coronary heart disease (CHD)/hypertension (HTN), asthma/chronic obstructive pulmonary disease (COPD), and congestive heart failure (CHF)/chronic kidney disease (CKD).
Purpose of the Study:
- To evaluate the clinical and economic impact of new DM programs.
- To assess the cost-effectiveness of DM interventions for major chronic disease groups.
- To identify trends in per member per month (PMPM) costs and total medical savings.
Main Methods:
- A comparative study design was used, comparing active DM program enrollees (IN group) with non-enrollees (OUT group).
- Data were collected from Blue Cross Blue Shield of Louisiana members aged 18-64 between March 2015 and February 2018.
- Multivariable models and difference-in-difference analysis were employed to compare PMPM costs and calculate medical savings over 1-3 years.
Main Results:
- Average PMPM costs remained stable for the IN cohort, while increasing for the OUT cohort over time.
- DM programs demonstrated potential for improving clinical outcomes, such as hemoglobin A1c levels.
- Significant PMPM savings were observed, reaching $53.72 after 3 years, with total savings exceeding $14.4 million for all programs combined.
Conclusions:
- Disease management programs for diabetes, CHD/HTN, CHF/CKD, and asthma/COPD are cost-effective.
- These programs show evidence of improving clinical outcomes.
- Implementing DM programs offers a viable strategy for managing chronic diseases and reducing healthcare expenditures.
Abstract:
Aims: Chronic diseases impose a substantial healthcare burden. This study sought to evaluate the clinical and economic impact of new disease management (DM) programs, targeting four major chronic disease groups: diabetes, coronary heart disease (CHD)/hypertension (HTN), asthma/chronic obstructive pulmonary disease (COPD), and congestive heart failure (CHF)/chronic kidney disease (CKD).Materials and methods: Between March 1, 2015, and February 28, 2018, members with Blue Cross Blue Shield of Louisiana insurance were contacted and enrolled in a DM program if they were aged 18 years through 64 years, eligible for a DM program, and had not been previously enrolled in a DM program. Active enrollees of a DM program ("IN" group) were compared to members who were not yet enrolled ("OUT" group). Average per member per month (PMPM) costs were aggregated annually to document any descriptive trends. Multivariable model estimates were used to compare PMPM costs for all IN subjects and all OUT subjects. Total medical savings were evaluated for the following time intervals: 1-12 months, 13-24 months, and 25-36 months.Results: For all four DM programs, average costs PMPM trended upward over time for the OUT cohort, while they remained relatively stable for the IN cohort. Some evidence also showed that DM programs improved clinical outcomes, such as hemoglobin A1c values. A difference in difference analysis showed PMPM savings for all four programs combined of $31.61, $50.45, and $53.72 after 1, 2, and 3 years, respectively. Multivariable modeling results showed total savings after 3 years of $14,460,174 for all DM programs combined.Limitations: Although multivariable models adjusted for several clinical, demographic, and economic characteristics; it is possible that some important confounders were missing due to lack of data.Conclusions: DM programs implemented to control diabetes, CHD/HTN, CHF/CKD, and asthma/COPD are cost-effective and show some evidence of improved clinical outcomes.

Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...
