          Abstract

          Objetivos: La mayoría de trabajos sobre costes de las técnicas de reproducción asistida (TRA) identifican el coste directo del procedimiento, sin considerar elementos como los costes estructurales o intermedios, de gran importancia. El objetivo de este trabajo es calcular el coste por proceso de las TRA realizadas en un hospital público en 2003 y compararlo con los resultados de 1998 en el mismo centro. Métodos: El estudio se realiza en la Unidad de Reproducción Humana (URH) del Hospital Universitario Virgen de las Nieves de Granada en 1998 y 2003. Partiendo de los costes totales de dicha unidad, y mediante una metodología de distribución de costes basada en la estructura de costes, calculamos el coste por proceso de las TRA realizadas en este centro, considerando los costes completos. Resultados: Entre 1998 y 2003, la actividad y los costes de la URH analizada evolucionan de forma distinta. El análisis de la actividad muestra la consolidación de técnicas, como la microinyección espermática (ICSI) y la desaparición de otras (ciclo sin reproducción asistida e inseminación artificial conyugal intracervical). En todos los procesos, los costes unitarios por ciclo y por embarazo disminuyen en el período analizado. Conclusiones: Se han producido importantes cambios en la estructura de costes de las TRA de la URH-HUVN entre 1998-2003. Mientras algunos procesos desaparecen, otros se consolidan con una elevada actividad. Los avances técnicos y las innovaciones organizativas, junto con un «efecto aprendizaje», han alterado la estructura de costes de las TRA.

          Objectives: Most studies on the costs of assisted reproductive technologies (ART) identify the total cost of the procedure with the direct cost, without considering important items such as overhead or intermediate costs. The objective of this study was to determine the cost per ART procedure in a public hospital in 2003 and to compare the results with those in the same hospital in 1998. Methods: Data from the Human Reproduction Unit of the Virgen de las Nieves University Hospital in Granada (Spain) from 1998 and 2003 were analyzed. Since the total costs of the unit were known, the cost of the distinct ART procedures performed in the hospital was calculated by means of a methodology for cost distribution. Results: Between 1998 and 2003, the activity and costs of the Human Reproduction Unit analyzed evolved differently. Analysis of activity showed that some techniques, such as intracytoplasmic sperm injection, were consolidated while others, such as stimulation without assisted reproduction or intracervical insemination were abandoned. In all procedures, unit costs per cycle and per delivery decreased in the period analyzed. Conclusions: Important changes took place in the structure of costs of ART in the Human Reproduction Unit of the Virgen de las Nieves University Hospital between 1998 and 2003. Some techniques were discontinued, while others gained importance. Technological advances and structural innovations, together with a «learning effect», modified the structure of ART-related costs.

          Intrauterine insemination or in-vitro fertilisation in idiopathic subfertility and male subfertility: a randomised trial and cost-effectiveness analysis.

          Couples affected by idiopathic subfertility or male subfertility have an estimated spontaneous conception rate of about 2% per cycle. Although various infertility treatments are available, counselling of a couple in their choice of treatment is difficult because of the lack of consistent data from good-quality comparative studies. We compared the results of treatment with intrauterine insemination (IUI) with those of in-vitro fertilisation (IVF), and did a cost-effectiveness analysis. In a prospective, randomised, parallel trial, 258 couples with idiopathic subfertility or male subfertility were treated for a maximum of six cycles of either IUI in the spontaneous cycle (IUI alone), IUI after mild ovarian hyperstimulation, or IVF. The primary endpoint was a pregnancy resulting in at least one livebirth after treatment. Cost-effectiveness based on real costs was studied by Markov chain analysis. 86 couples were assigned IUI alone, 85 IUI plus ovarian hyperstimulation, and 87 IVF. Ten couples dropped out before treatment began. Although the pregnancy rate per cycle was higher in the IVF group than in the IUI groups (12.2% vs 7.4% and 8.7%, respectively; p=0.09), the cumulative pregnancy rate for IVF was not significantly better than that for IUI. Couples in the IVF group were more likely than those in the IUI groups to give up treatment before their maximum of six attempts (37 [42%] drop-outs vs 13 [15%] and 14 [16%], respectively; p<0.01). The woman's age was the only factor that influenced a couple's chance of success. IUI was a more cost-effective treatment than IVF (costs per pregnancy resulting in at least one livebirth 8423-10661 Dutch guilders [US$4511-5710] for IUI vs 27409 Dutch guilders [US$14679] for IVF). Couples with idiopathic or male subfertility should be counselled that IUI offers the same likelihood of successful pregnancy as IVF, and is a more cost-effective approach. IUI in the spontaneous cycle carries fewer health risks than does IUI after mild hormonal stimulation and is therefore the first-choice treatment.

            Use of GnRH antagonists in ovarian stimulation for assisted reproductive technologies compared to the long protocol. Meta-analysis.

            The use of GnRH antagonists has revolutionized ovarian stimulation for assisted reproduction. Two GnRH antagonists are clinically available, namely, cetrorelix and ganirelix. Several studies have directly compared these new stimulation protocols against the long GnRH agonist protocol. To evaluate whether there is a reduction in cases of ovarian hyperstimulation syndrome (OHSS) and/or a reduction in pregnancy rates, a meta-analysis was performed. There was a significant reduction of OHSS cases in the cetrorelix studies (odds ratio, OR, 0.23; 95% confidence interval, CI, 0.10-0.54), but no reduction for ganirelix (OR 1.13; 95% CI 0.24-5.31). The incidence of OHSS degree III cases was reduced in the cetrorelix protocols as compared to the long protocol to a nearly significant degree (OR 0.26; 95% CI 0.07-1.01). Ganirelix did not reduce the incidence of OHSS degree III at all (OR 1.08; 95% CI 0.27-4.38). The pregnancy rate per cycle was significantly lower in the ganirelix protocols than in the long protocol (OR 0.76; 95% CI 0.59-0.98). The studies using cetrorelix showed quite similar, not significantly different results for the antagonist and the long protocol groups for the pregnancy rate per cycle (OR 0.91; 95% Cl 0.68-1.22). From the data one can conclude that cetrorelix but not ganirelix will reduce the incidence of cases of OHSS and that cetrorelix but not ganirelix will result in the same pregnancy rates as the long protocol. Several possibilities to explain this phenomenon are discussed.

              Cost-effectiveness modelling of recombinant FSH versus urinary FSH in assisted reproduction techniques in the UK.

              The purpose of this study was to undertake an economic evaluation to compare the cost-effectiveness of recombinant (r)FSH with urinary (u)FSH for attaining clinical pregnancy with assisted reproduction. Mathematical modelling was utilized incorporating a Markovian decision framework and a Monte Carlo simulation. Statistical representations of recurrent events over time were incorporated into a decision analysis involving fresh and frozen cycles in any sequence (after the first fresh embryo transfer cycle) over three successive assisted reproduction attempts. The mean values of transition probabilities were derived from randomized controlled clinical trials and published reports. The distributions of these transition probabilities were agreed upon by a panel of experts. Cost data for procedures and drugs were derived and validated according to the perspectives of the National Health Service and private clinics in the UK. The study involved 5000 Monte-Carlo simulations of treatment on a Markov cohort of 100 000 patients. The total number of pregnancies attained was significantly higher in the rFSH (40 575) compared with the uFSH (37 358) group. The cost per successful pregnancy was significantly lower for rFSH (5906 pounds sterling) compared with uFSH (6060 pounds sterling) and overall, fewer cycles of treatment were required with rFSH to achieve an ongoing pregnancy. The incremental cost-effectiveness ratio is 4148 pounds sterling for each additional clinical pregnancy with rFSH. In addition to the increased effectiveness of rFSH in ART, this study demonstrated that it is more cost-effective and more efficient than uFSH in attaining an ongoing pregnancy.
