RESUMO
AIM: to evaluate the medical and economic efficiency of prenatal diagnostics of fetal chromosomal abnormalities (CA) in pregnant women in Moscow using a non-invasive prenatal test (NIPT) as a second-line model. A comparative analysis of the medical and economic efficiency of standard prenatal screening and prenatal screening with NIPT in groups of pregnant women, registered in Moscow, with high and medium fetal CA risk was carried out. Analysis was based on the number of children born with CA and the costs of medical care (direct costs) and social payments (indirect costs), calculated for both scenarios. Following standard prenatal screening 111 children with CA would be born, following prenatal screening with NIPT - only 26. Including NIPT in prenatal diagnostics increases direct costs by 299.97 million rubles and reduces annual indirect costs from 61.19 to 28.95 million rubles. Starting from the 13th year of using NIPT the estimated effect of reducing indirect costs would exceed direct costs. NIPT in prenatal diagnostics can increase the detection of fetal CA and reduce indirect costs. Assessing the indirect costs in economic efficiency enhances the accuracy of the estimate.
