Can Technology-Based Physical Activity Programs for Chronic Obstructive Pulmonary Disease Be Cost-Effective?

Objective: To evaluate the cost-effectiveness of a technology-based physical activity (PA) intervention for chronic obstructive pulmonary disease (COPD). Design: A secondary data analysis was performed from a randomized controlled trial in COPD of an activity monitor alone or an activity monitor plus a web-based PA intervention. Models estimated cost per quality-adjusted life year (QALY) and incremental cost-effectiveness ratios (ICERs) compared with usual care. Results: The estimated ICER for both groups was below the willingness-to-pay threshold of $50,000/QALY (activity monitor alone = $10,437/QALY; website plus activity monitor intervention = $13,065/QALY). A probabilistic simulation estimated 76% of the activity monitor-alone group and 78% of the intervention group simulations to be cost-effective. Conclusion(s): Both the activity monitor-alone group and the activity monitor plus website group were cost-effective at the base case by using conventional willingness-to-pay thresholds. Further research would benefit from a more direct estimate of health utilities and downstream health care costs. Clinical Trials.gov NCT01102777.

Automated summary

The study evaluated the cost-effectiveness of a technology-based physical activity intervention for COPD and found that both intervention methods were cost-effective. Further research should focus on more direct estimates of health utilities and downstream healthcare costs.
