Objective
To evaluate cost-effectiveness of the following three treatments of uterine fibroids in a population of premenopausal women who wish to preserve their uteri: myomectomy, MR-guided focused ultrasound (MRgFUS) and uterine artery embolization (UAE).
Methods
A decision analytic Markov model was constructed. Cost-effectiveness was calculated in terms of U.S. dollars per quality adjusted life year (QALY) over five years. Two types of costs were calculated: direct costs only, and the sum of direct and indirect (productivity) costs. Women in the hypothetical cohort were assessed for treatment type eligibility, were treated based on eligibility, and experienced adequate or inadequate symptom relief. Additional treatment (myomectomy) occurred for inadequate symptom relief or recurrence. Sensitivity analysis was conducted to evaluate uncertainty in the model parameters.
Results
In the base-case, myomectomy, MRgFUS and UAE had the following combinations of mean cost and mean QALYs, respectively: ($15,459, 3.957), ($15,274, 3.953) and ($18,653, 3.943). When incorporating productivity costs, MRgFUS incurred mean cost of $21,232; myomectomy $22,599; and UAE $22,819. Using probabilistic sensitivity analysis (PSA) and excluding productivity costs, myomectomy was cost-effective at almost every decision threshold. Using PSA and incorporating productivity costs, myomectomy was cost-effective at decision thresholds above $105,000/QALY; MRgFUS between $30,000-$105,000/QALY; and UAE below $30,000/QALY.
Conclusions
Myomectomy, MRgFUS, and UAE were similarly effective in terms of QALYs gained. Depending on assumptions about costs and willingness-to-pay for additional QALYs, all three treatments can be deemed cost-effective in a five year time frame.
