Objective To undertake a cost effectiveness analysis comparing first and second generation endometrial ablative techniques, hysterectomy, and the levonorgestrel releasing intrauterine system (Mirena) for treating heavy menstrual bleeding.
Design Model based economic evaluation with data from an individual patient data meta-analysis supplemented with cost and outcome data from published sources taking an NHS (National Health Service) perspective. A state transition (Markov) model was developed, the structure being informed by the reviews of the trials and clinical input. A subgroup analysis, one way sensitivity analysis, and probabilistic sensitivity analysis were also carried out.
Population Four hypothetical cohorts of women with heavy menstrual bleeding.
Interventions One of four alternative strategies: Mirena, first or second generation endometrial ablation techniques, or hysterectomy.
Main outcome measures Cost effectiveness based on incremental cost per quality adjusted life year (QALY).
Results Hysterectomy is the preferred strategy for the first intervention for heavy menstrual bleeding. Although hysterectomy is more expensive, it produces more QALYs relative to other remaining strategies and is likely to be considered cost effective. The incremental cost effectiveness ratio for hysterectomy compared with Mirena is £1440 (€1633, $2350) per additional QALY. The incremental cost effectiveness ratio for hysterectomy compared with second generation ablation is £970 per additional QALY.
Conclusion In light of the acceptable thresholds used by the National Institute for Health and Clinical Excellence, hysterectomy would be considered the preferred strategy for the treatment of heavy menstrual bleeding. The results concur with those of other studies but are highly sensitive to utility values used in the analysis.
Contributors: TER, PB, SB, and JD contributed to the design of the whole project and obtained funding. TER and PB designed the model based cost effectiveness analysis. TER prepared the manuscript as lead writer. AT under the supervision of PB constructed the model with advice from KC and SB. AT under the supervision of TER and PB identified and collected the required data on costs and effectiveness for the model and carried out the analysis. LM, JD, KC, RC, and SB provided the relevant data from the individual patient data meta-analysis. TR, PB, and AT interpreted the results with assistance from KC and SB. TR is guarantor.
Funding: This study was funded by the National Institute for Health Research Health Technology Assessment Programme (05/45/02).
