Cost savings associated with a web-based physical activity intervention for COPD.

Area of Science:

• Health Economics
• Pulmonology
• Digital Health

Background:

• Chronic obstructive pulmonary disease (COPD) poses a significant economic burden on healthcare systems.
• Effective interventions are needed to manage COPD exacerbations and reduce associated costs.
• Web-mediated physical activity interventions show promise in managing chronic conditions.

Purpose of the Study:

• To estimate the cost savings of a pedometer-based, web-mediated physical activity intervention for US veterans with COPD.
• To analyze the economic impact of such interventions on COPD-related healthcare expenditures.

Main Methods:

• Economic analysis using a decision tree model from a healthcare system perspective.
• Incorporated intervention costs, COPD-related acute exacerbation risks, and associated healthcare utilization (emergency visits, hospitalizations).
• Utilized probabilistic sensitivity analysis with Monte Carlo simulation to assess model uncertainty.

Main Results:

• The intervention group incurred estimated costs of $4236 per participant versus $7913 in the control group, yielding a 1-year saving of $3677 per participant.
• Probabilistic sensitivity analysis confirmed robust cost savings, with a mean difference of $4582 (95% PI, $4084-$5080).
• Cost savings were primarily driven by reduced risk of exacerbations, hospitalizations, and associated costs.

Conclusions:

• A pedometer-based, web-mediated physical activity intervention leads to substantial cost savings for COPD management.
• Wider implementation of this intervention can significantly alleviate the economic burden of COPD for payers and patients.
• This approach offers a cost-effective strategy for improving physical activity and managing COPD.
