Efficacy, acceptability and safety of medication abortion in low-income, urban Latina women

BACKGROUND

Health care providers may be reluctant to offer medication abortion to low-income, non-English-speaking populations. Concerns include lack of patient interest, incorrect use of misoprostol at home, missing mandatory follow-up visits and inappropriate use of emergency services. We describe the appeal, acceptability, safety and follow-up rates of medication abortion in a low-income Latina population in New York City.

STUDY DESIGN

Nested analysis of 270 subjects up to 63 days' gestation enrolled in a multicenter trial of medication abortion comparing different mifepristone-misoprostol intervals. After receiving mifepristone, subjects were instructed on home use of misoprostol, what to do in an emergency and when to return.

RESULTS

This population was predominantly Spanish-speaking, unmarried, poor and publicly insured. Ninety-six percent took the misoprostol at home correctly, 90% returned as scheduled without reminders and 2% were lost to follow-up. Ninety-six percent described the experience as positive or neutral and 94% would recommend medication abortion to a friend. Three serious adverse events occurred and women accessed emergency services appropriately.

CONCLUSION

Medication abortion can be a very appealing, safe and effective option in low-income, non-English-speaking populations.

Mifepristone-misoprostol abortion: a trial in rural and urban Maharashtra, India

As several important policy questions remain regarding the use of medical abortion in developing countries, we investigated the safety, efficacy, and acceptability of mifepristone-misoprostol abortion in the outpatient family planning departments of two urban hospitals and one rural hospital in India. Nine-hundred women (with gestations of < or =63 days in the urban sites and < or =56 days in the rural site) received 600 mg mifepristone followed 48 h later by 400 microg oral misoprostol in the clinic. Four point four percent or fewer urban women and 1.0% rural women were lost to follow-up. Perfect and typical-use failure rates were low at all sites. While rural women reported fewer side effects at all sites, the vast majority of women were satisfied with their medical abortions. Medical abortion can be offered safely, effectively, and acceptably in the outpatient family planning departments of urban and rural hospitals in India.

Elective abortion as a primary health service in rural India: experience with manual vacuum aspiration

India allows abortion up to 20 weeks of pregnancy but places restrictions on abortion facilities and providers. Abortion services are especially deficient in rural areas. Although vacuum aspiration is safer, sharp curettage continues to be used by providers as they lack relevant training. This paper describes the provision of first trimester abortion services using manual vacuum aspiration (MVA) in a rural clinic in the state of Rajasthan over a four-year period. Non-use of anaesthesia increased safety and allowed women to return early to a normal routine. Of 534 women, none suffered major complications; 16 required repeat evacuation and the procedure failed in two. We recommend that models based on MVA and including medical methods be piloted in rural areas of a number of states of the country, to establish the feasibility of delivering first trimester abortion as a primary health service. Ways to increase access to second trimester procedures are also required. Current requirements for certification of private facilities are excessive and the process of obtaining certification is arduous. The law in India does not extend these norms to government facilities, which remain under-equipped and lack trained providers. We recommend that certification of facilities be liberalized and applied equally to government and private institutions. There is also a need to rapidly increase training capacity across the country.

Accuracy of assessment of pregnancy duration by women seeking early abortions

BACKGROUND

Advances in medical abortion might allow women seeking early abortions to terminate their pregnancies safely and effectively without medical supervision. We investigated whether such women can calculate pregnancy duration accurately, a key step in unsupervised use.

METHODS

422 women seeking first-trimester abortions in two clinics (Pune, India, and Atlanta, USA) used a simple worksheet and calendar to calculate the duration of gestation from the date of last menstrual period (LMP) and/or of unprotected intercourse. Clinicians then used standard clinic practices to estimate pregnancy duration. We compared the two sets of estimates, focusing on women who fell into the "caution zone" (ie, had pregnancy durations >8 weeks according to providers, but < or =8 weeks by their own estimates).

FINDINGS

The participants were generally representative of the women seeking abortion at the two clinics. 217 (97.7%) of 222 women in Atlanta and 173 (86.5%) of 200 in Pune could produce an estimate of pregnancy duration. Most (85.4% in Atlanta; 93.6% in Pune) of these estimates were within 2 weeks of those made by providers. For estimates based on LMP, only 10.0% (exact 95% CI 6.2-15.0) of women in Atlanta and 9.8% (5.8-15.3) in Pune fell into the caution zone. For estimates based on a date of intercourse, just 7.7% (4.0-13.1) of women in Atlanta and 3.4% (0-17.8) in Pune fell into the caution zone, although fewer women could use this method.

INTERPRETATION

The vast majority of women seeking first-trimester abortion in this study could accurately calculate pregnancy duration within a margin of error clinically inconsequential for safe use of unsupervised medical abortion.
