| Summary: | In vitro fertilization (IVF) is used to help infertile couples achieve a live birth. Clinical studies have suggested that multiple, consecutive cycles of IVF can increase live birth rate significantly. Others have documented improved live birth rates from the use of new laboratory techniques for preimplantation genetic screening (PGS). This genetic screening technique seeks to determine the ploidy of the embryo prior to implantation into the woman. To date, no study has examined the cost-effectiveness of using IVF in conjunction with PGS compared to that of IVF alone for 3 consecutive cycles in achieving a live birth. This study compared the incremental cost-effectiveness ratios (ICER) from each intervention arm based on the clinical probabilities for each outcome and this study was grounded in the protection motivation theory. Costs were obtained from secondary sources, such as the literature and government databases. The model was constructed using a decision-analytical approach that allowed for z test statistical analysis of the outcomes, where the ICER is the dependent variable and the independent variables are the 2 interventions. The robustness of the model was tested through univariate and probabilistic sensitivity analysis and stratified by age groups. The results showed that PGS with IVF was cost-effective for women aged under 40 and women aged 40-42, but not for women over 42. Based on a willingness-to-pay threshold of $100,000, IVF with PGS was the most cost-effective strategy in all age groups. The positive social change implication of this study is such that understanding the costs associated with a new technology to achieve a live birth is significant for society to help guide clinical treatment of these patients. |
