RESUMO

OBJECTIVE: To assess the comparative health and economic outcomes associated with three alternative first-trimester abortion techniques in Mexico City and to examine the policy implications of increasing access to safe abortion modalities within a restrictive setting. DESIGN: Cost-effectiveness analysis. SETTING: Mexico City. POPULATION: Reproductive-aged women with unintended pregnancy seeking first-trimester abortion. METHODS: Synthesising the best available data, a computer-based model simulates induced abortion and its potential complications and is used to assess the cost-effectiveness of alternative safe modalities for first-trimester pregnancy termination: (1) hospital-based dilatation and curettage (D&C), (2) hospital-based manual vacuum aspiration (MVA), (3) clinic-based MVA and (4) medical abortion using vaginal misoprostol. MAIN OUTCOME MEASURES: Number of complications, lifetime costs, life expectancy, quality-adjusted life expectancy. RESULTS: In comparison to the magnitude of health gains associated with all safe abortion modalities, the relative differences between strategies were more pronounced in terms of their economic costs. Assuming all options were equally available, clinic-based MVA was the least costly and most effective. Medical abortion with misoprostol provided comparable benefits to D&C, but cost substantially less. Enhanced access to safe abortion was always more influential than shifting between safe abortion modalities. CONCLUSIONS: This study demonstrates that the provision of safe abortion is cost-effective and will result in reduced complications, decreased mortality and substantial cost savings compared with unsafe abortion. In Mexico City, shifting from a practice of hospital-based D&C to clinic-based MVA and enhancing access to medical abortion will have the best chance to minimise abortion-related morbidity and mortality.

RESUMO

OBJECTIVES: To investigate current clinical use of misoprostol for the treatment of a range of reproductive health indications by providers in Brazil, Jamaica, and the United States. METHODS: Using a 'snowball' sampling technique, we surveyed 228 gynecologists and obstetricians in Brazil (n=123), Jamaica (n=52), and the United States (n=53). RESULTS: Providers use misoprostol for labor induction (46%), postpartum hemorrhage (8%), intra-uterine fetal death (61%), cervical priming (21%), missed abortion (57%), and incomplete abortion (16%) as well as first and second trimester abortion induction (27% and 13%, respectively). CONCLUSIONS: There is considerable variation in the regimens used; moreover, the regimens commonly used in clinical practice often differ from those recommended in the medical literature. While misoprostol is an appealing alternative for many reproductive health indications in developing countries, the varied regimens and lack of registration raise critical medical and policy questions.

RESUMO

OBJECTIVE: To determine whether multiple courses of emergency contraceptive therapy supplied in advance of need would tempt women using barrier methods to take risks with their more effective ongoing contraceptive methods. METHODS: We randomly assigned 411 condom users attending an urban family planning clinic in Pune, India, to receive either information about emergency contraception along with three courses of therapy to keep in case of need, or to receive only information, including that about the locations where they could obtain emergency contraception if needed. For up to 1 year, women returned quarterly for follow-up, answering questions about unprotected intercourse, emergency contraceptive use, pregnancies, sexually transmitted infections, and acceptability. RESULTS: Women given advance supplies reported unprotected intercourse at rates nearly identical to those among women given only information (0.012 versus 0.016 acts per month). Among those who did have unprotected intercourse, however, supply recipients were nearly twice as likely (79% versus 44%) to have taken emergency contraception, although numbers were too small to permit statistically significant inferences. No women used emergency contraception more than once during the study, even though everyone in the advance-supplies group had extra doses available. All women found knowing about emergency contraception useful, and all those receiving only information wished they had received supplies as well. CONCLUSION: Multiple emergency contraception doses supplied in advance did not tempt condom users to risk unprotected intercourse. After unprotected intercourse, however, those with pills on hand used them more often. Women found advance provision useful.

RESUMO

Many biomedical aspects of emergency contraception have been investigated and documented for >30 years now. A large number of social science questions, however, remain to be answered. In this article, we review the rapidly growing but geographically lopsided literature on this topic. Using computer database searches supplemented by reference reviews and professional correspondence with those active in the field, we gathered literature on the social science and service delivery aspects of emergency contraception published in English up through December 1998, as well as a few unpublished papers from the same time and slightly later, representing regions where published material is practically nonexistent. Methodologically acceptable papers are summarized in our tables and text, and form the basis for suggested improvements in existing emergency contraceptive services. The review also offers ideas for designing new emergency contraception services where they do not yet exist. We conclude by proposing an agenda for further social science research in this area.

RESUMO

Vaginal microbicides are being developed in an attempt to expand women's and men's options for protecting themselves against HIV and other sexually transmitted infections. Taking account of men's attitudes during product development and introduction could increase the likelihood that products are acceptable and used. To capture the perspectives of urban and rural men from a range of cultural settings, we conducted focus group discussions with taxi drivers and farmers in Zimbabwe, Mexico and the USA. These explored HIV/STD risk perception and prevention strategies, desirable characteristics of vaginal products and of a microbicide, and attitudes towards use of a potential product. Men were generally supportive of the idea of a microbicide; urban somewhat more than rural men. Most thought microbicides would be preferable to condoms though many raised concerns about potential side effects. The men wanted these products to be as inexpensive and readily available as condoms, and differed as to whether a woman should have permission from her partner to use it. For them to be widely used, the men thought these products must not only be safe and effective, but should also have no negative effect on sexual pleasure. When a product becomes available, introductory messages must explain the limits on its effectiveness and encourage use with condoms. Further research is needed on definitions of pleasurable sex and the ramifications of this for microbicide formulation, and on partner communication around issues of sexuality and prevention of infection.

RESUMO

Increased access to medical methods of abortion could significantly reduce maternal mortality, especially in developing countries. In light of the political and commercial difficulties in distributing the abortifacient mifepristone, the widely studied mifepristone-misoprostol regimen may not be sufficiently available in the near future. Thus, researchers have begun to look for alternative regimens, including regimens using misoprostol alone. This article reviews the current available evidence on the potential of a misoprostol-alone regimen for medical abortion. Although the data are varied and difficult to compare, recent studies indicate that a misoprostol-alone regimen could be safe and effective as a method of medical abortion. Misoprostol is widely marketed around the world for its other indications and is inexpensive, stable in tropical climates, easy to transport, and simple to administer. A misoprostol-alone regimen of medical abortion could thus greatly improve the access to safe medical abortion services by women in developing countries.


PIP: Studies have been conducted to examine the potential of misoprostol alone for early termination of pregnancy. These studies were done by Norman et al. (1991), Creinin and Vittinghoff (1994), Bugalho et al. (1996), Koopersmith and Mishell (1996), Carbonell et al. (two studies: 1997, 1998), and Jain et al. (1998). The designs, population sampling methods and regimens varied from study to study. Thus, comparison of results has been difficult. Overall, though, findings indicate that a misoprostol-alone regimen could be safe and effective as a method of medical abortion. This regimen could greatly improve access to safe medical abortion services for women in developing countries, which in turn would lead to a significant reduction in maternal mortality.
