Key Highlights
- Duloxetine 120 mg produced more QALYs than amitriptyline (10.40 vs 9.99)
- Incremental cost-effectiveness ratio of duloxetine 120 mg is $1,536 per QALY
- Duloxetine 120 mg is cost-saving relative to amitriptyline when indirect costs are included
- Pregabalin 450 mg generated fewer QALYs compared to duloxetine 120 mg despite higher costs
- Sensitivity analyses indicate duloxetine 120 mg has the highest probability of being cost-effective
Guideline-Based Recommendations
Diagnosis
- Assess fibromyalgia severity and impact on quality of life
Management
- Consider duloxetine 120 mg as a first-line treatment option
Monitoring & Follow-up
