The National Institute for Clinical Excellence has recently changed its guidelines on discounting costs and effects in economic evaluations. In common with most other regulatory bodies it now requires that health effects should be discounted at the same rate as costs. We show that the guideline leads to sub-optimal decisions because it fails to account for the changing value of health. NICE (and other regulatory bodies) should either use differential discounting or stipulate how the changing value of health should otherwise be dealt with. We also show how binding health service budget constraints should be incorporated in evaluations.
BACKGROUND: Our prospective randomized controlled trial was designed to assess whether the use of GnRH antagonists can improve the success rate of controlled ovarian stimulation (COS)/intrauterine insemination (IUI) treatments, via inhibition of the premature LH rise. METHODS: A total of 104 patients were randomly divided, using a randomization list, into two groups: in group A (n = 52), recombinant FSH (rFSH) was given with GnRH antagonist Cetrorelix, and in group B (n = 52), the patients received rFSH alone in a manner similar to that of group A. The primary outcome measure was clinical pregnancy rate per couple. RESULTS: The pregnancy rate per patient was 53.8% in group A and 30.8% in group B (P = 0.017). The rate of premature LH surge was 7% in group A and 35% in group B (P < 0.0001). A premature luteinization was observed in two cycles of 144 in group A (1.4%) and in 16 cycles of 154 in group B (10.4%) (P = 0.001). The mean values of LH and progesterone were significantly lower in patients receiving GnRH antagonist than in those who did not (3.3 +/- 3.3 mIU/ml in group A versus 9.9 +/- 7.9 mIU/ml in group B, P < 0.0001, for LH; 1.3 +/- 1.1 ng/ml versus 2.1 +/- 1.9 ng/ml for group A and B, respectively, P < 0.0001, for progesterone). CONCLUSION: The use of GnRH antagonist in COS/IUI cycles improves pregnancy rate, preventing the premature LH rise and luteinization.
