Comparative effectiveness, safety and acceptability of medical abortion at home and in a clinic: a systematic review

OBJETIVO: Comparar la efectividad, la seguridad y la aceptación de los abortos médicos practicados en el domicilio con aquellos realizados en la clínica. MÉTODOS: Se realizó una búsqueda sistemática de ensayos clínicos controlados aleatorizados y de estudios de cohortes prospectivos, comparando los abortos médicos realizados en el domicilio y en la clínica. Se realizaron búsquedas en el Registro Central de Cochrane de Ensayos Controlados, EMBASE, MEDLINE y Popline. Los resultados de interés principales fueron el fracaso para abortar completamente, los efectos secundarios y la aceptabilidad. Se calcularon las tasas de probabilidad y sus intervalos de confianza (IC) del 95%. Se reunieron los cálculos aproximados utilizando un modelo de efectos aleatorios. RESULTADOS: Nueve estudios cumplieron los criterios de inclusión (n=4522 participantes).Todos fueron estudios de cohortes prospectivos que utilizaron mifepristona y misoprostol para inducir al aborto. El aborto completo se consiguió en el 86- 97% de las mujeres que se sometieron a un aborto en el domicilio (n=3478) y entre el 80% y el 99% de aquellas mujeres que se sometieron a un aborto en una clínica (n = 1044). Los análisis agrupados de todos los estudios no mostraron diferencias en las tasas de aborto completo entre los grupos (tasa de probabilidad=0,8; IC del 95%: 0,5-1,5). Las complicaciones graves del aborto fueron poco frecuentes. El dolor y los vómitos duraron 0,3 días más en aquellas mujeres a las que se les administró misoprostol en el domicilio, en comparación con las que recibieron el tratamiento en la clínica. Las mujeres que optaron por un aborto médico en el domicilio mostraron un mayor grado de satisfacción, que las llevaría a elegir el método de nuevo y recomendárselo a una amiga, que aquellas mujeres que abortaron en la clínica. CONCLUSIÓN: El aborto en el domicilio es seguro siempre que el lugar cuente con las condiciones incluidas en los estudios. Los estudios de cohortes prospectivos por país no han mostrado diferencias en cuanto a efectividad o aceptabilidad entre abortos médicos en el domicilio y en la clínica.

Effectiveness of medical abortion with mifepristone and buccal misoprostol through 59 gestational days

BACKGROUND: From 2001 to March 2006, Planned Parenthood Federation of America (Planned Parenthood) health centers throughout the United States provided medical abortions principally by a regimen of oral mifepristone, followed 24-48 h later by vaginal misoprostol. In late March 2006, analyses of serious uterine infections following medical abortions led Planned Parenthood to change the route of misoprostol administration and to employ additional measures to minimize subsequent serious uterine infections. In August 2006, we conducted an extensive audit of medical abortions with the new buccal misoprostol regimen so that patients could be given accurate information about the success rate of the new regimen. OBJECTIVES: We sought to evaluate the effectiveness of the buccal medical abortion regimen and to examine correlates of its success during routine service delivery. METHODS: In 2006, audits were conducted in 10 large urban service points to estimate the success rates of the buccal regimen. Success was defined as medical abortion without vacuum aspiration. These audits also permitted estimates of success rates with oral misoprostol following mifepristone in a subset in which 98% of the subjects stemmed from two sites. RESULTS: The effectiveness of the buccal misoprostol-mifepristone regimen was 98.3% for women with gestational ages below 60 days. The oral misoprostol-mifepristone regimen, used by 278 women with a gestational age below 50 days, had a success rate of 96.8%. CONCLUSION: In conjunction with 200 mg of mifepristone, use of 800 mcg of buccal misoprostol up to 59 days of gestation is as effective as the use of 800 mcg of vaginal misoprostol up to 63 days of gestation.

Knowledge of medical abortion among Brazilian medical students

OBJECTIVE: To assess the knowledge of Brazilian medical students regarding medical abortion (MA) and the use of misoprostol for MA, and to investigate factors influencing their knowledge. METHODS: All students from 3 medical schools in São Paulo State were invited to complete a pretested structured questionnaire with precoded response categories. A set of 12 statements on the use and effects of misoprostol for MA assessed their level of knowledge. Of about 1260 students invited to participate in the study, 874 completed the questionnaire, yielding a response rate of 69%. The Ï (2) test was used for the bivariate analysis, which was followed by multiple regression analysis. RESULTS: Although all students in their final year of medical school had heard of misoprostol for termination of pregnancy, and 88% reported having heard how to use it, only 8% showed satisfactory knowledge of its use and effects. Academic level was the only factor associated with the indicators of knowledge investigated. CONCLUSION: The very poor knowledge of misoprostol use for MA demonstrated by the medical students surveyed at 3 medical schools makes the review and updating of the curriculum urgently necessary.

Women’s experiences with the use of medical abortion in a legally restricted context: the case of Argentina

This article presents the findings of a qualitative study exploring the experiences of women living in Buenos Aires Metropolitan Area, Argentina, with the use of misoprostol for inducing an abortion. We asked women about the range of decisions they had to make, their emotions, the physical experience, strategies they needed to use, including seeking health care advice and in dealing with a clandestine medical abortion, and their overall evaluation of the experience. An in-depth interview schedule was used. The women had either used misoprostol and sought counselling or care at a public hospital (n=24) or had used misoprostol based on the advice of a local hotline, information from the internet or from other women (n=21). Four stages in the women’s experiences were identified: how the decision to terminate the pregnancy was taken, how the medication was obtained, how the tablets were used, and reflections on the outcome whether or not they sought medical advice. Safety and privacy were key in deciding to use medical abortion. Access to the medication was the main obstacle, requiring a prescription or a friendly drugstore. Correct information about the number of pills to use and dosage intervals was the least easy to obtain and caused concerns. The possibility of choosing a time of privacy and having the company of a close one was highlighted as a unique advantage of medical abortion. Efforts to improve abortion law, policy and service provision in Argentina in order to ensure the best possible conditions for use of medical abortion by women should be redoubled.
