Hypothesis
Is internet-delivered cognitive behavior therapy (CBT) a cost-effective treatment for irritable bowel syndrome (IBS)?
Conclusion
Internet-delivered CBT appears to generate health gains in IBS treatment and is associated with cost-savings from a societal perspective.
Supporting Evidence
- The treatment group showed significant cost reductions of $16,806 per successfully treated case.
- 36% of participants in the treatment condition experienced clinically significant improvement.
- The cost-effectiveness analysis indicated that internet-delivered CBT is cost-saving from a societal perspective.
Takeaway
This study found that online therapy can help people with IBS feel better and save money for society.
Methodology
Participants with IBS were randomized to receive either internet-delivered CBT or participate in a discussion forum, with cost data assessed at multiple follow-ups.
Potential Biases
Potential bias due to the control group being aware of their future treatment.
Limitations
The study relied on self-reported cost data, which may introduce inaccuracies, and the control group was aware they would eventually receive treatment.
