Implementing medical abortion with mifepristone and misoprostol in Norway 1998-2013

Interpregnancy interval and adverse pregnancy outcomes among pregnancies following miscarriages or induced abortions in Norway (2008-2016): A cohort study

BACKGROUND

The World Health Organization recommends to wait at least 6 months after miscarriage and induced abortion before becoming pregnant again to avoid complications in the next pregnancy, although the evidence-based underlying this recommendation is scarce. We aimed to investigate the risk of adverse pregnancy outcomes-preterm birth (PTB), spontaneous PTB, small for gestational age (SGA) birth, large for gestational age (LGA) birth, preeclampsia, and gestational diabetes mellitus (GDM)-by interpregnancy interval (IPI) for births following a previous miscarriage or induced abortion.

METHODS AND FINDINGS

We conducted a cohort study using a total of 49,058 births following a previous miscarriage and 23,707 births following a previous induced abortion in Norway between 2008 and 2016. We modeled the relationship between IPI and 6 adverse pregnancy outcomes separately for births after miscarriages and births after induced abortions. We used log-binomial regression to estimate unadjusted and adjusted relative risk (aRR) and 95% confidence intervals (CIs). In the adjusted model, we included maternal age, gravidity, and year of birth measured at the time of the index (after interval) births. In a sensitivity analysis, we further adjusted for smoking during pregnancy and prepregnancy body mass index. Compared to births with an IPI of 6 to 11 months after miscarriages (10.1%), there were lower risks of SGA births among births with an IPI of <3 months (8.6%) (aRR 0.85, 95% CI: 0.79, 0.92, p < 0.01) and 3 to 5 months (9.0%) (aRR 0.90, 95% CI: 0.83, 0.97, p = 0.01). An IPI of <3 months after a miscarriage (3.3%) was also associated with lower risk of GDM (aRR 0.84, 95% CI: 0.75, 0.96, p = 0.01) as compared to an IPI of 6 to 11 months (4.5%). For births following an induced abortion, an IPI <3 months (11.5%) was associated with a nonsignificant but increased risk of SGA (aRR 1.16, 95% CI: 0.99, 1.36, p = 0.07) as compared to an IPI of 6 to 11 months (10.0%), while the risk of LGA was lower among those with an IPI 3 to 5 months (8.0%) (aRR 0.84, 95% CI: 0.72, 0.98, p = 0.03) compared to an IPI of 6 to 11 months (9.4%). There was no observed association between adverse pregnancy outcomes with an IPI >12 months after either a miscarriage or induced abortion (p > 0.05), with the exception of an increased risk of GDM among women with an IPI of 12 to 17 months (5.8%) (aRR 1.20, 95% CI: 1.02, 1.40, p = 0.02), 18 to 23 months (6.2%) (aRR 1.24, 95% CI: 1.02, 1.50, p = 0.03), and ≥24 months (6.4%) (aRR 1.14, 95% CI: 0.97, 1.34, p = 0.10) compared to an IPI of 6 to 11 months (4.5%) after a miscarriage. Inherent to retrospective registry-based studies, we did not have information on potential confounders such as pregnancy intention and health-seeking bahaviour. Furthermore, we only had information on miscarriages that resulted in contact with the healthcare system.

CONCLUSIONS

Our study suggests that conceiving within 3 months after a miscarriage or an induced abortion is not associated with increased risks of adverse pregnancy outcomes. In combination with previous research, these results suggest that women could attempt pregnancy soon after a previous miscarriage or induced abortion without increasing perinatal health risks.

Induced abortion and future use of IVF treatment; A nationwide register study

OBJECTIVE

In this nationwide study we assessed the use and factors associated with future in vitro fertilization (IVF) treatment after induced abortion.

MATERIALS AND METHODS

The study population was collected by means of record linkage between Finnish national registers. All women who underwent induced abortion between 2000 and 2009 in Finland were identified through the Register of Induced Abortions (n = 88 522). The study group consisted of women who underwent induced abortion and subsequently had an IVF treatment (n = 379); the comparison group were all women who had a spontaneous pregnancy and delivery 12-24 months after the index abortion (n = 7434). Demographic characteristics at the time of index abortion, and factors associated with the abortion (gestational age at abortion, indication and method of abortion, complications after abortion) were compared between the study groups. Logistic regression was used to assess whether some of the demographic characteristics or abortion associated factors increased the use of IVF treatment in the future.

RESULTS

The proportion of women with IVF treatment after induced abortion in the whole cohort was 0.4%. Women needing IVF treatment were older, of a higher socioeconomic status, and had fewer previous induced abortions and deliveries compared to women in the comparison group. No statistically significant differences were observed in the gestational age (≤ 12 weeks or >12 weeks of gestation) at abortion, method or complications of abortion. In multivariable analysis higher age increased, and history of previous deliveries or one or two abortions decreased the use of IVF.

CONCLUSIONS

Infertility necessitating the use of IVF treatment after induced abortion is uncommon. The factors associated with use of IVF after abortion are those generally recognized as risk factors of infertility. Abortion-related outcomes are not associated with an increased need of future IVF-treatment.

Beyond the law: Misoprostol and medical abortion in Dar es Salaam, Tanzania

Misoprostol has during the past few years become an important obstetric drug used for different purposes both within and outside hospitals in Tanzania. In this paper, we analyze how misoprostol is perceived, accessed and used off-label as an abortion drug in the city and region of Dar es Salaam. The study took place in Dar es Salaam's three districts from July to November 2015, and had a qualitative explorative approach. We carried out in-depth interviews (42) with the following main categories of informants: women having undergone medical abortion (15), health care workers with experiences from post abortion care (16) and drug vendors (11). Focus group discussions (10) were carried out with young women. A client simulation study was carried out in 64 drugstores across Dar es Salaam assessing the availability of misoprostol and the advice given concerning its use. In addition, shorter qualitative interviews were carried out with representatives of NGOs and public agencies working with sexual and reproductive health issues (17). Our findings reveal that in Dar es Salaam, misoprostol is well known, available and accessed for abortion purposes through drugstores and health providers. Women tend to prefer misoprostol over other abortion methods since it allows for a private, low-cost, safer and less uncomfortable abortion experience. But, while misoprostol facilitates women's agency in the process of seeking abortion, a series of obstacles shaped by a restrictive abortion law and an unregulated pharmaceutical market hinder its safe use. Central obstacles are profit-seeking providers, suboptimal user instructions and poor provider follow-up. In the discussion of the material we draw upon Van der Geest, Hardon and Whyte's concept of the 'social life of pharmaceuticals' and indicate the ways in which misoprostol acts as an agent of change in the social relations connected to abortion.

Service provider perceptions of the trend in severity of symptoms and complications in women admitted following an incomplete abortion

Background

Sri Lankan abortion law which dates back to the year 1883, and still unchanged, only allows a legal termination when the mother's life is in danger. Many studies undertaken in the country estimates that even in the light of such a backdrop, and with a high contraceptive prevalence rate, many women attempt an abortion when faced with an unwanted pregnancy. This study aims to describe the changes in abortion-related complications in the country over a period of time and explore the reasons for any changes in severity of symptoms among women hospitalized following an abortion based on the perceptions of healthcare service providers.

Method

Using an interviewer guide, in-depth interviews were carried out among 30 service providers of post abortion care with more than 5 years of experience in obstetrics and gynecology in Sri Lanka.

Results

Service providers perceived that the number of women presenting to hospitals after an induced abortion caused by a mechanical method is minimal or not at all at present. Over time, a significant reduction is seen in the number of women presenting with any abortion-related complications and the severity of complications has also reduced significantly. The common method of termination at present identified by the providers was the use of "drugs" or "the drug - Misoprostol."

Conclusion

Over the years, women appear to have switched from surgical and mechanical methods to medical means (drugs) to induce an abortion and this change has contributed to reduce the severity of complications.
