Tratamiento médico del aborto del primer trimestre: igual eficacia, más eficiencia

Abstract

BackgroundEarly pregnancy loss occurs in 10-20% of all clinical pregnancies, 85% being prior to week 12 of amenorrhea. Miscarriage entails a very significant burden on healthcare resources, reaching a national economic cost in the United Kingdom of £471 million per year (€533.06 million), a figure that can be extrapolated to other industrialized countries. According to a recent systematic review, there are no well-designed trials in first-trimester pregnancies that provide consolidated evidence on what is the best first-trimester abortion treatment method, and there are different studies that have tried to demonstrate cost reduction with contradictory results. Material and methodsAn observational, retrospective and longitudinal design study was carried out. 892 patients diagnosed with spontaneous abortion during the first trimester of pregnancy were reviewed, in the period between January 2013 and December 2016.In our study, we wanted to evaluate the efficacy of vaginal misoprostol as a medical treatment for spontaneous abortion in the first trimester, in comparison with obstetric curettage-evacuator, and to quantify the difference in the costs of both procedures through a cost minimization study. costs. ResultsOf the 892 recruited patients, medical treatment with misoprostol was performed in 517 (57.95%) and surgical treatment by curettage in 375 (42.05%).The effectiveness of medical treatment was 82% (426/517). With respect to surgical treatment the effectiveness of 100%. The success rate of medical treatment was higher in the subgroup of patients with incomplete abortion (92.9%), compared to the anembryonic gestation (85.7%) and delayed abortion (78.2%) groups. ConclusionsThe medical treatment of abortion is a safe management and accepted by the patients. The adequate selection of candidate patients leads to an increase in the success rate and a decrease in costs. In our study, an important total saving of €576,847.92 (37.14%) with respect to surgical treatment will be reduced. Given that the effectiveness is comparable and patient satisfaction is high, although it could be improved, we believe that with adequate information and homogenization of the applied treatment, it is safe.
