Surgical and medical second trimester abortion in South Africa: a cross-sectional study

Comparison of the effect of vaginal misoprostol and evening primrose oil capsule with misoprostol alone on the consequences of abortion in women with intrauterine fetal death: a randomized clinical trial

BACKGROUND

Misoprostol is the choice drug for inducing an abortion with intrauterine fetal death, but it has several side effects that increase with accumulating the dose received. Induction abortion with cheap and non-invasive methods with minimal complications is essential. This study aimed to compare the effect vaginal misoprostol plus vaginal evening primrose oil capsule with vaginal misoprostol alone on the consequences of abortion in pregnant women with intrauterine fetal death at 12-20 weeks of pregnancy.

METHODS

This study is a randomized, triple-blind clinical trial with two parallel groups at a ratio of 1:1. We randomized 82 women with indications of termination of pregnancy due to intrauterine fetal death into two groups. The experimental group (n = 42) received 200 mcg of misoprostol tablet with 1000 mg evening primrose oil capsule intravaginal. The control group (n = 40) received 200 mcg of misoprostol tablet with 1000 mg evening primrose oil placebo capsule intravaginal. Both groups received the drugs every 4 h for up to five doses. The primary outcome was the mean induction-to-fetal expulsion interval. Secondary outcomes were the mean dose of misoprostol, the highest pain intensity in the induction-to-fetal expulsion interval, the frequency of participants requiring blood transfusion, curettage, and the frequency of side effects of misoprostol or evening primrose oil. Pain intensity was measured through the Visual Analog Scale.

RESULTS

The mean age of the experimental group was 32.30 ± 6.19 years, and the control group was 30.27 ± 7.68 years. The mean gestational age of the experimental group was 15.29 ± 2.26 weeks, and the control group was 15.10 ± 1.89 weeks. The mean induction-to-fetal expulsion interval in the experimental group (3.12 ± 2.17 h) was significantly lower than that in the control group (8.40 ± 4.1 h) (p < 0.001). The mean dose of misoprostol received in the experimental group (271.42 ± 115.39 mcg) was significantly lower than that in the control group (520 ± 201.53 mcg) (p < 0.001). Also, the mean pain intensity in the experimental group (5.02 ± 0.60) was significantly lower than that in the control group (8.65 ± 1.001) (p < 0.001). The two groups were not significantly different in the frequency of blood transfusion requirements, analgesia and drug side effects. The need for curettage in the experimental group (4.8%) was significantly lower than that in the control group (47.5%) (p < 0.001).

CONCLUSIONS

Vaginal administration of evening primrose oil with misoprostol reduced duration of time of fetal expulsion, pain intensity, mean dose of misoprostol received, and the need for curettage in participants. Therefore, we suggest this method for induced abortion in women with intrauterine fetal death.

Pain, Side Effects, and Abortion Experience Among People Seeking Abortion Care in the Second Trimester

Background:

There is limited documentation about pain and side effects associated with dilation and evacuation (D&E) abortion, yet, pain and side effects are important factors that can affect a client's abortion experience. In 2016, Hope Clinic for Women, an independent abortion clinic in Illinois, altered its cervical preparation protocols before D&E to reduce the total time of the abortion process and improve the client experience. This analysis addresses the gap in data on client experience of abortion in the later second trimester by evaluating pain, side effects, and acceptability by gestational age.

Methods:

Abortion clients obtaining services at the clinic between March 2017 and June 2018 were eligible to participate if they had viable singleton pregnancies of 16–23.6 weeks' gestation, spoke English, and were at least 18 years old. Eligible participants completed a two-part survey about their abortion experience.

Results:

We found that respondents seeking abortion care at later gestations in the second trimester were more likely to report pain during their abortions. We did not find any association between side effects and gestational age.

Conclusion:

Although most respondents were prepared for the pain they experienced, some reported experiencing more pain than they expected, and more effective pain relief was commonly reported as a way to improve the service. More research on patient experiences of later abortion is needed, particularly on experiences of pain and options for pain management.

Could routine pregnancy self-testing facilitate earlier recognition of unintended pregnancy? A feasibility study among South African women

INTRODUCTION

We explored whether routine pregnancy self-testing is feasible and acceptable to women at risk of late recognition of pregnancy as a strategy to facilitate early entry into either antenatal or abortion care.

METHODS

A feasibility study among South African sexually active women not desiring pregnancy within 1 year, and not using long-acting or injectable contraceptives. At recruitment, we provided five free urine pregnancy tests for self-testing on the first day of each of the next 3 months. We sent monthly text reminders to use the tests with requests for no-cost text replies. Our main outcome was the proportion of participants self-testing within 5 days of the text reminder over three consecutive months. Other outcomes were ease of use of tests, preference for self-testing versus clinic testing, acceptability of routine self-testing (all binary responses followed by open response options) and response to text messages (four-point Likert scale).

RESULTS

We followed up 71/76 (93%) participants. Two confirmed new pregnancies at the first scheduled test and completed exit interviews, and 64/69 (93%) self-reported completing all three monthly tests. Self-testing was easy to do (66/71, 93%); advantages were convenience (21/71, 30%) and privacy (18/71, 25%), while the main disadvantage was no nurse present to advise (17/71, 24%). Most would recommend monthly testing (70/71, 99%). Text reminders were generally not bothersome (57/71, 80%); 35/69 (51%) participants replied with test results over all three months.

CONCLUSION

Providing free pregnancy tests to women at risk of late recognition of pregnancy is feasible to strengthen early confirmation of pregnancy status.

Comparison of surgical versus medical termination of pregnancy between 13-20 weeks of gestation in Ethiopia: A quasi-experimental study

Background

Dilation and evacuation is a method of second trimester pregnancy termination introduced recently in Ethiopia. However, little is known about the safety and effectiveness of this method in an Ethiopian setting. Therefore, the study is intended to determine the safety and effectiveness of dilation and evacuation for surgical abortion as compared to medical abortion between 13–20 weeks’ gestational age.

Methods

This is a quasi-experimental study of women receiving second trimester termination of pregnancy between 13–20 weeks. Patients were allocated to either medical or surgical abortion based on their preference. A structured questionnaire was used to collect demographic information and clinical data upon admission. Procedure related information was collected after the procedure was completed and before the patient was discharged. Additionally, women were contacted 2 weeks after the procedure to evaluate for post-procedural complications. The primary outcome of the study was a composite complication rate. Data were collected using Open Data Kit and then analyzed using Stata version 14.2. Univariate analyses were performed using means (standard deviation), or medians (interquartile range) when the distribution was not normal. Multiple logistic regression was also performed to control for confounders.

Results

Two hundred nineteen women chose medical abortion and 60 chose surgical abortion. The composite complication rate is not significantly different among medical and surgical abortion patients (15% versus 10%; p = 0.52). Nine patients (4.1%) in the medical arm required additional intervention to complete the abortion, while none of the surgical abortion patients required additional intervention. Median (IQR) hospital stay was significantly longer in the medical group at 24 (12–24) hours versus 6(4–6) hours in the surgical group p<0.001.

Conclusion

From the current study findings, we concluded that there is no difference in safety between surgical and medical methods of abortion. This study demonstrates that surgical abortion can be used as a safe and effective alternative to medical abortion and should be offered equivalently with medical abortion, per the patient’s preference.

Medical regimens for abortion at 12 weeks and above: a systematic review and meta-analysis

Background

Mifepristone and misoprostol are recommended for second-trimester medical abortion, but consensus is unclear on the ideal regimen.

Objectives

The objectives were to systematically review randomized controlled trials (RCTs) investigating efficacy, safety and satisfaction of medical abortion at ≥ 12 weeks' gestation.

Data sources

We searched PubMed, Popline, Embase, Global Index Medicus, Cochrane Controlled Register of Trials and International Clinical Trials Registry Platform from January 2008 to May 2017.

Study eligibility participants and interventions

We included RCTs on medical abortion at ≥ 12 weeks' gestation using mifepristone and/or misoprostol. We excluded studies with spontaneous abortion, fetal demise and mechanical cervical ripening and those not reporting ongoing pregnancy (OP).

Study appraisal and synthesis methods

After extracting prespecified data and assessing risk of bias in accordance with the Cochrane handbook, we used Revman5 software to combine data and GRADE to assess certainty of evidence.

Results

We included 43 of the 1894 references identified. Combination mifepristone-misoprostol had lower rates of OP [risk ratio (RR) 0.12, 95% confidence interval (CI) 0.04-0.35] vs. misoprostol only. A 24-h interval between mifepristone and misoprostol had lower OP rate at 24 h than simultaneous dosing (RR 3.13, 95% CI 1.23-7.94). Every 3-h dosing had lower OP rate at 48 h (RR 0.39, 95% CI 0.17-0.88).

Limitations

Direct comparisons of buccal misoprostol to sublingual or vaginal routes after mifepristone were limited. Evidence from clinical trials on how to best manage women with prior uterine incisions was lacking.

Conclusion

Our analysis supports the use of mifepristone 200 mg 1 to 2 days before misoprostol 400 mcg vaginally every 3 h at ≥ 12 weeks' gestation.

Implications

Where available, providers should use mifepristone plus misoprostol for second-trimester medical abortion. Vaginal misoprostol appears to be most efficacious with fewest side effects, but sublingual and buccal routes are also acceptable.

Determinants and Outcome of Safe Second Trimester Medical Abortion at Jimma University Medical Center, Southwest Ethiopia

Background

Although the vast majority of abortions are performed in the first trimester, still 10–15% of terminations of pregnancies have taken place in the second trimester globally. As compared to first trimester, second trimester abortions disproportionately contribute to maternal morbidity and mortality especially in low-income countries where access to safe second trimester abortion is limited. The objective of this study was to identify factors affecting and outcome of induced safe second trimester medical abortion in Jimma University medical center, Southwest Ethiopia.

Methods

Institution based cross-sectional study design was used to conduct a study among women who seek safe second trimester medical abortion services and admitted at gynecology ward. All (201) eligible study subjects included were those who came for safe medical abortion service during data collection period. Data collected using pretested structured questionnaire through exit-interviewing and some clinical data abstracted from their chart. The data was entered into EpData version 3.1 then exported to SPSS version 21.0 for analysis. Variables with P-value less than 0.25 in bivariate analysis were entered into the final predictive model. Multivariable logistic regression was used to identify determinants with 95% CI and P-value < 0.05. Hosmer and Lemeshow test were used to check model fitness at P-value of 0.05. Ethical clearance was obtained and confidentiality kept using codes and patient's chart number.

Results

In this study the response rate was 98.1%. Out of 201 women who participated in the study and were addmitted for safe second trimester medical abortion, 154 (76.6%) of them had complete abortion without any complication while the remaining 47 (23.4%) had incomplete abortion with one or more complication. Previous experience of abortion [AOR= 6.00, 95% CI= (3.77, 8.88)], gestational age [AOR=0.90, 95% CI= (0.07, 0.99)], parity [AOR=2.38, 95% CI= (1.04, 3.69)], cervical status [AOR=8.00, 95% CI= (5.72, 10.02)], overall waiting time for more than two weeks [AOR=0.53, 95% CI= (0.50, 0.96)], overall waiting time for two weeks [AOR=0.05, 95% CI= (0.01, 0.45)], and moderate anemia -(Hgb:7-10g/dl)-[AOR=0.07,95% CI= (0.01, 0.16)] were independent predictors for outcome of safe second trimester medical abortion.

Conclusion

This finding implied that proportion of complete abortion without any complication overweighs incomplete abortions with one or more complication through induced safe second trimester medical abortion method. The outcome is strongly determined by gestational age, cervical status, previous experience of abortion, parity, moderate anemia, and overall waiting time. Induced second trimester medical abortion is already known as an effective and safe method. However, much should be done to reduce proportion of incomplete abortions by minimizing overall waiting time through intervening at low gestational age. Therefore, it is recommended that safe second trimester medical abortion services should be continued under a certain legal circumstances so as to reduce maternal morbidity and mortality.

Providing safe abortion services: Experiences and perspectives of providers in South Africa

Despite abortion being legally available on request up to and including the gestational age of 12 weeks in South Africa, barriers to access remain. Barriers include provider opposition to abortion and a shortage of trained and willing providers, which has implications for access to safe abortion services. Exploring the factors that determine providers' levels of involvement in abortion services can facilitate improvements in service provision. Providers' conceptualizations of abortion are influenced by numerous factors, including moral and religious views, in which abortion is perceived by some as a sin, whereas others view access to safe abortions as an important component of a woman's right to reproductive autonomy and choice. Barriers to service provision include limited abortion and values clarification training and misinterpretation of conscientious objection. Providers have difficulties with the emotional and visual impact of second trimester abortions. There is an urgent need to address provider shortage, and abortion education and training need to be included in medical and nursing curricula to ensure sustaining abortion services.

An analysis of delays among women accessing second-trimester abortion in the public sector in South Africa

OBJECTIVES

To identify key delays and associated factors in women's pathway to second-trimester abortion that could inform strategies to increase earlier presentation.

STUDY DESIGN

We performed a secondary analysis using data collected from May 2012 to June 2013 as part of a randomized controlled trial among women having abortion at 13.0-20.0 weeks at a public hospital in South Africa. We used ultrasound and participant interview data to calculate 3 key intervals: (1) conception to suspicion of pregnancy, (2) suspicion to first healthcare visit for abortion, and (3) first healthcare visit to abortion procedure. We compared intervals for women at 13-15.0 weeks versus 15.1-20.0 weeks gestation at abortion using Wilcoxon rank-sum tests and tested for associations between gestational age at key events using multivariable linear regression.

RESULTS

Median (interquartile range[IQR]) durations for the 3 intervals among women at 13-15 weeks (n=93) compared to 15.1-20 weeks (n=63) gestation were: (1) 36 days (IQR 21-53 days) versus 62 days (36-71 days), p<.001; (2) 29 days (IQR 15-46 days) versus 23 days (IQR 11-39 days), p=.64; (3) 14 days (IQR 7-21 days) versus 14 days (IQR 12-21 days), p=.32. Multivariable logistic regression showed marginal associations between gestational age at suspicion of pregnancy and no prior pregnancy (aOR=3.8, 95% CI 1.0-14.6) and living in informal housing (aOR=3.1, 95% CI 1.0-9.1). Gestational age on the day of the abortion procedure was significantly associated with living in informal housing (aOR=3.1, 95% CI 1.4-6.6).

CONCLUSION

The only differences in delay in obtaining second trimester abortion between South African women having an earlier and later second trimester procedure is due to longer time to suspect pregnancy.

IMPLICATIONS

Interventions to improve early pregnancy recognition should be explored and referral processes should be streamlined to avoid unnecessary delays accessing abortion care and possibly reduce the proportion of abortions performed later in the second trimester in South Africa.

Safe abortion in South Africa: "We have wonderful laws but we don't have people to implement those laws"

In South Africa, abortion was legalized in 1996, during the nation's transition from apartheid to independence and democracy, under the Choice on Termination of Pregnancy Act (CTOPA). The law drew from both a public health and rights-based framework. A coalition of advocates played a key role in passage. In the years after the CTOPA was passed, abortion services were expanded-in part through a 2008 amendment that allowed trained registered nurses to provide abortions-and deaths from unsafe abortions decreased. However, there have been hurdles to implementation, including competing health priorities such as HIV/AIDS, and a high number of conscientious objectors. There is a geographic disparity in accessibility of abortion services between provinces as well as between urban and rural areas. Women seeking legal abortions face a lack of accessible information on where to obtain an abortion, often experience stigma at facilities, and many obtain illegal procedures.

The costs and cost effectiveness of providing second-trimester medical and surgical safe abortion services in Western Cape Province, South Africa

Background

In South Africa, access to second-trimester abortion services, which are generally performed using medical induction with misoprostol alone, is challenging for many women. We aimed to estimate the costs and cost effectiveness of providing three safe second-trimester abortion services (dilation and evacuation (D&E)), medical induction with mifepristone and misoprostol (MI-combined), or medical induction with misoprostol alone (MI-misoprostol)) in Western Cape Province, South Africa to aid policymakers with planning for service provision in South Africa and similar settings.

Methods

We derived clinical outcomes data for this economic evaluation from two previously conducted clinical studies. In 2013–2014, we collected cost data from three public hospitals where the studies took place. We collected cost data from the health service perspective through micro-costing activities, including discussions with site staff. We used decision tree analysis to estimate average costs per patient interaction (e.g. first visit, procedure visit, etc.), the total average cost per procedure, and cost-effectiveness in terms of the cost per complete abortion. We discounted equipment costs at 3%, and present the results in 2015 US dollars.

Results

D&E services were the least costly and the most cost-effective at $91.17 per complete abortion. MI-combined was also less costly and more cost-effective (at $298.03 per complete abortion) than MI-misoprostol (at $375.31 per complete abortion), in part due to a shortened inpatient stay. However, an overlap in the plausible cost ranges for the two medical procedures suggests that the two may have equivalent costs in some circumstances.

Conclusion

D&E was most cost-effective in this analysis. However, due to resistance from health care providers and other barriers, these services are not widely available and scale-up is challenging. Given South Africa’s reliance on medical induction, switching to the combined regimen could result in greater access to second-trimester services due to shorter inpatient stays without increasing costs.

Women's experiences seeking informal sector abortion services in Cape Town, South Africa: a descriptive study

Background

In settings where abortion is legally restricted, or permitted but not widely accessible, women face significant barriers to abortion access, sometimes leading them to seek services outside legal facilities. The advent of medication abortion has further increased the prevalence of informal sector abortion. This study investigates the reasons for attempting self-induction, methods used, complications, and sources of information about informal sector abortion, and tests a specific recruitment method which could lead to improved estimates of informal sector abortion prevalence among an at-risk population.

Methods

We recruited women who have sought informal sector abortion services in Cape Town, South Africa using respondent driven sampling (RDS). An initial seed recruiter was responsible for initiating recruitment using a structured coupon system. Participants completed face-to-face questionnaires, which included information about demographics, informal sector abortion seeking, and safe abortion access needs.

Results

We enrolled 42 women, nearly one-third of whom reported they were sex workers. Thirty-four women (81%) reported having had one informal sector abortion within the past 5 years, 14% reported having had two, and 5% reported having had three. These women consumed home remedies, herbal mixtures from traditional healers, or tablets from an unregistered provider. Twelve sought additional care for potential warning signs of complications. Privacy and fear of mistreatment at public sector facilities were among the main reported reasons for attempting informal sector abortion. Most women (67%) cited other community members as their source of information about informal sector abortion; posted signs and fliers in public spaces also served as an important source of information.

Conclusions

Women are attempting informal sector abortion because they seek privacy and fear mistreatment and stigma in health facilities. Some were unaware how or where to seek formal sector services, or believed the cost was too high. Many informal methods are ineffective and unsafe, leading to potential warning signs of complications and continued pregnancy. Sex workers may be at particular risk of unsafe abortion. Based on these results, it is essential that future studies sample women outside of the formal health sector. The use of innovative sampling methods would greatly improve our knowledge about informal sector abortion in South Africa.

Abortion attitudes among South Africans: findings from the 2013 social attitudes survey

Abortion is legal in South Africa, but over half of abortions remain unsafe there. Evidence suggests women who are (Black) African, of lower socioeconomic status, living with HIV, or residents of Gauteng, KwaZulu-Natal, or Limpopo provinces are disproportionately vulnerable to morbidity or mortality from unsafe abortion. Negative attitudes toward abortion have been documented in purposively sampled studies, yet it remains unclear what attitudes exist nationally or whether they differ across sociodemographic groups, with implications for inequities in service accessibility and health. In the current study, we analysed nationally representative data from 2013 to estimate the prevalence of negative abortion attitudes in South Africa and to identify racial, socioeconomic and geographic differences. More respondents felt abortion was 'always wrong' in the case of family poverty (75.4%) as compared to foetal anomaly (55%), and over half of respondents felt abortion was 'always wrong' in both cases (52.5%). Using binary logistic regression models, we found significantly higher odds of negative abortion attitudes among non-Xhosa African and Coloured respondents (compared to Xhosa respondents), those with primary education or less, and residents of Gauteng and Limpopo (compared to Western Cape). We contextualise and discuss these findings using a human rights-based approach to health.

Clinical Outcomes and Women's Experiences before and after the Introduction of Mifepristone into Second-Trimester Medical Abortion Services in South Africa

Objective

To document clinical outcomes and women’s experiences following the introduction of mifepristone into South African public sector second-trimester medical abortion services, and compare with historic cohorts receiving misoprostol-only.

Methods

Repeated cross-sectional observational studies documented service delivery and experiences of women undergoing second-trimester medical abortion in public sector hospitals in the Western Cape, South Africa. Women recruited to the study in 2008 (n = 84) and 2010 (n = 58) received misoprostol only. Those recruited in 2014 (n = 208) received mifepristone and misoprostol. Consenting women were interviewed during hospitalization by study fieldworkers with respect to socio-demographic information, reproductive history, and their experiences with the abortion. Clinical details were extracted from medical charts following discharge. Telephone follow-up interviews to record delayed complications were conducted 2–4 weeks after discharge for the 2014 cohort.

Results

The 2014 cohort received 200 mg mifepristone, which was self-administered 24–48 hours prior to admission. For all cohorts, following hospital admission, initial misoprostol doses were generally administered vaginally: 800 mcg in the 2014 cohort and 600 mcg in the earlier cohorts. Women received subsequent doses of misoprostol 400 mcg orally every 3–4 hours until fetal expulsion. Thereafter, uterine evacuation of placental tissue was performed as needed. With one exception, all women in all cohorts expelled the fetus. Median time-to-fetal expulsion was reduced to 8.0 hours from 14.5 hours (p<0.001) in the mifepristone compared to the 2010 misoprostol-only cohort (time of fetal expulsion was not recorded in 2008). Uterine evacuation of placental tissue using curettage or vacuum aspiration was more often performed (76% vs. 58%, p<0.001) for those receiving mifepristone; major complication rates were unchanged. Hospitalization duration and extreme pain levels were reduced (p<0.001), but side effects of medication were similar or more common for the mifepristone cohort. Overall satisfaction remained unchanged (95% vs. 91%), while other acceptability measures were higher (p<0.001) for the mifepristone compared to the misoprostol-only cohorts.

Conclusion

The introduction of a combined mifepristone-misoprostol regimen into public sector second-trimester medical abortion services in South Africa has been successful with shorter time-to-abortion events, less extreme pain and greater acceptability for women. High rates of uterine evacuation for placental tissue need to be addressed.

The costs of accessing abortion in South Africa: women's costs associated with second-trimester abortion services in Western Cape Province

OBJECTIVES

To assess women's costs of accessing second-trimester labor induction and dilation and evacuation (D&E) services at four public hospitals in Western Cape Province, South Africa.

STUDY DESIGN

From April to August 2010, in interviews immediately after completion of their abortion, we asked women about specific direct and indirect costs incurred. We collected information on recurring costs (i.e., per visit) and one-time expenditures and calculated total costs.

RESULTS

In total, 194 patients participated (136 D&E; 58 induction). Their median age was 26; 37.6% reported being employed or doing paid work. Most (73.2%) women visited two different facilities, including the study facility, while seeking the procedure. Induction women reported a median of three required visits [interquartile range (IQR) 2.0-3.0] to the study facility, while D&E women reported two required visits [IQR 1.0-2.0]. Twenty-seven percent of women missed work due to the procedure, and few (4.6%) paid for childcare. At each visit, almost all women (180, 92.8%) paid for transportation costs and reported additional one-time costs (177, 91.2%) such as sanitary supplies or doctor's fees. The total median cost incurred per woman was $21.23 [IQR 11.94-44.68]. Roughly half (49.0%) received help with these costs.

CONCLUSIONS

Although technically offered freely or low cost in the public sector, women accessing second-trimester abortion lost income and incurred costs for transport, fees, supplies and childcare. Their total costs could be reduced by minimizing the number of required visits to facilities and freely offering supplies such as sanitary pads and pregnancy tests.

IMPLICATIONS

Limited access to second-trimester, safe abortion services in South Africa may result in some women incurring unnecessary costs. Women make multiple visits in attempting to obtain an abortion, often because of facility or health systems requirements, and incur costs for lost income, child care, transport, fees and supplies.

A randomized trial of misoprostol versus laminaria before dilation and evacuation in South Africa

OBJECTIVE

To compare complication rates, efficacy and acceptability of buccal misoprostol to laminaria for cervical preparation before dilation and evacuation (D&E) in South Africa.

STUDY DESIGN

We performed a randomized, single-blind trial comparing buccal misoprostol 400 mcg (1-2 doses, administered at least 3 h before D&E) to laminaria inserted the day before D&E among women at 13-19 weeks gestation. The primary outcome was expulsion of the fetus prior to surgery; secondary outcomes included other complications, need for mechanical dilation, procedure duration, side effects and satisfaction. Required sample size was 176 to detect a difference in expulsion of 20% to 5%, with a two-sided alpha of 0.05 and 80% power.

RESULTS

Due to slow enrollment and low incidence of primary outcome, the study was stopped early. One hundred fifty-nine women were randomized, and 156 received treatment (78 in each group). Mean gestational age was 14.8 weeks (range, 13.0-18.6 weeks). Complications were rare and did not differ by group [three in each group; odds ratio (OR), 1; 95% confidence interval (CI), 0.20-5.11]; this included two expulsions in the misoprostol group (2.6%). Misoprostol participants were more likely to require mechanical dilation compared to those receiving laminaria (35% vs. 8%; OR, 6.4; 95% CI, 2.4-16.5). The proportion of women reporting each side effect was similar except for diarrhea (21.3% in misoprostol group vs. 5.2% in laminaria group, p=0.004). Procedure time and satisfaction did not differ between groups.

CONCLUSIONS

Both misoprostol and laminaria are associated with a low complication rate in this setting, although misoprostol requires more mechanical dilation and causes more diarrhea.

IMPLICATIONS

Cervical preparation using either laminaria or misoprostol can be safely used before D&E up to at least 19 weeks. Physicians using misoprostol must be skilled at mechanical dilation, since this is commonly required.

Acceptability and clinical outcomes of first- and second-trimester surgical abortion by suction aspiration in Colombia

OBJECTIVE(S)

Since partial decriminalization of abortion in Colombia, Oriéntame has provided legal abortion services through 15 weeks gestation in an outpatient primary care setting. We sought to document the safety and acceptability of the second trimester compared to the first-trimester surgical abortion in this setting.

STUDY DESIGN

This was a prospective cohort study using a consecutive sample of 100 women undergoing surgical first-trimester abortion (11 weeks 6 days gestational age or less) and 200 women undergoing second-trimester abortion (12 weeks 0 days-15 weeks 0 days) over a 5-month period in 2012. After obtaining informed consent, a trained interviewer collected demographic and clinical information from direct observation and the patient's clinical chart. The interviewer asked questions after the procedure regarding satisfaction with the procedure, physical pain and emotional discomfort. Fifteen days later, the interviewer assessed satisfaction with the procedure and any delayed complications.

RESULTS

There were no major complications and seven minor complications. Average measured blood loss was 37.87 mL in the first trimester and 109 mL in the second trimester (p<.001). Following the procedure, more second-trimester patients reported being very satisfied (81% vs. 94%, p=.006). Satisfaction was similar between groups at follow-up. There were no differences in reported emotional discomfort after the procedure or at follow-up, with the majority reporting no emotional discomfort. The majority of women (99%) stated that they would recommend the clinic to a friend or family member.

CONCLUSIONS

Second-trimester surgical abortion in an outpatient primary care setting in Colombia can be provided safely, and satisfaction with these services is high.

IMPLICATIONS

This is one of the first studies from Latin America, a region with a high proportion of maternal mortality due to unsafe abortion, which documents the safety and acceptability of surgical abortion in an outpatient primary care setting. Findings could support increased access to safe abortion services, particularly in the second trimester.

Buccal misoprostol plus laminaria for cervical preparation before dilation and evacuation at 21-23 weeks of gestation: a randomized controlled trial

OBJECTIVE

To describe the effectiveness of buccal misoprostol as an adjunct to laminaria for cervical ripening before later second-trimester abortion by dilation and evacuation (D&E).

METHODS

A randomized, double-blinded, placebo-controlled trial of 196 women undergoing D&E between 21 and 23 weeks of gestation. Subjects had overnight laminaria and 400 mcg buccal misoprostol or placebo 3-4 h before the abortion. We used logarithmic transformation of the primary outcome--D&E procedure duration--to achieve a normal distribution.

RESULTS

Mean D&E duration was 1.7 min shorter with misoprostol (p=.02). The median duration was 9.7 versus 10.4 min in the misoprostol and placebo groups, respectively (p=.09). Cervical dilation was slightly greater with misoprostol (median 75 mm vs. 73 mm, p=.04); however, physicians did not find the misoprostol D&Es easier to complete. Half of subjects reported severe pain after misoprostol vs. 11% with placebo (p<.001).

CONCLUSION

Adjuvant buccal misoprostol results in slightly shorter D&Es at the cost of more side effects.

THE CHALLENGES OF OFFERING PUBLIC SECOND TRIMESTER ABORTION SERVICES IN SOUTH AFRICA: HEALTH CARE PROVIDERS' PERSPECTIVES

Around 25% of abortions in South Africa are performed in the second trimester. This study aimed to better understand what doctors, nurses and hospital managers involved in second trimester abortion care thought about these services and how they could be improved. Nineteen in-depth interviews with abortion-related service providers and managers in the Western Cape Province, South Africa, were undertaken. Data were analysed using a thematic analysis approach. Participants expressed resistance to the dilation and evacuation (D&E) procedure, as this required more active provider involvement. Medical abortion was preferred as it required less provider involvement in the abortion process. A shortage of providers willing to perform D&E resulted in most public sector services being outsourced to private sector doctors. Respondents noted an increased demand for services and a concomitant lack of infrastructure, physical space and personnel to respond to these demands, sometimes resulting in fragmented or poor quality care. At medical induction sites, most thought introducing the combined mifepristone–misoprostol regimen would improve service capacity, although they were concerned about cost. Improving contraceptive services was also seen as a much-needed intervention to improve care and prevent abortion. Ongoing training, including values clarification, as well as emotional support and team-building for providers are needed to ensure sustainable, high-quality second trimester abortion services.
