Second-trimester postabortion care for ruptured membranes, fetal demise, and incomplete abortion

Evaluating women’s acceptability of treatment of incomplete second trimester abortion using misoprostol provided by midwives compared with physicians: a mixed methods study

Background

Studies evaluating task sharing in postabortion care have mainly focused on women in first trimester and many lack a qualitative component. We aimed to evaluate patient acceptability of treatment of incomplete second trimester abortion using misoprostol provided by midwives compared with physicians and also gained a deeper understanding of the patients’ lived treatment experiences in Uganda.

Methods

Our mixed methods study combined 1140 structured interview data from a randomized controlled equivalence trial and in-depth interviews (n = 28) among women managed with misoprostol for second trimester incomplete abortion at 14 public health facilities in Uganda. Acceptability, our main outcome, was measured at the 14-day follow-up visit using a structured questionnaire as a composite variable of: 1) treatment experience (as expected/ better than expected/ worse than expected), and 2) satisfaction - if patient would recommend the treatment to a friend or choose the method again. We used generalized mixed effects models to obtain the risk difference in acceptable post abortion care between midwife and physician groups. We used inductive content analysis for qualitative data.

Results

From 14th August 2018 to 16th November 2021, we assessed 7190 women for eligibility and randomized 1191 (593 to midwife and 598 to physician). We successfully followed up 1140 women and 1071 (94%) found the treatment acceptable. The adjusted risk difference was 1.2% (95% CI, − 1.2 to 3.6%) between the two groups, and within our predefined equivalence range of − 5 to + 5%. Treatment success and feeling calm and safe after treatment enhanced acceptability while experience of side effects and worrying bleeding patterns reduced satisfaction.

Conclusions

Misoprostol treatment of uncomplicated second trimester incomplete abortion was equally and highly acceptable to women when care was provided by midwives compared with physicians. In settings that lack adequate staffing levels of physicians or where midwives are available to provide misoprostol, task sharing second trimester medical PAC with midwives increases patient’s access to postabortion care services.

Approximately 9.6% of abortion-related deaths occur in Sub-Saharan Africa. These deaths can be prevented if unintended pregnancies are avoided, women can access safe abortions within the expectations of the country’s laws, and post abortion care (PAC) services are provided equitably. Previous research shows that women with abortion complications in the first trimester of pregnancy can be treated with misoprostol by either midwives or physicians. This sharing of tasks between the midwives and physicians is safe, effective, and acceptable. However, there is a gap in evidence on task sharing in the second trimester. To check practicability of task sharing in second trimester, we aimed to evaluate patient acceptability of treatment of incomplete second trimester abortion using misoprostol provided by midwives compared with physicians and also gained a deeper understanding of the patients’ lived treatment experiences. Our study therefore combined quantitative and qualitative approaches. Women’s acceptability of misoprostol treatment for incomplete second trimester abortion was found to be equally acceptable when provided by midwives compared with physicians. Treatment success, feeling calm and safe after treatment increased acceptability, while experience of side effects and worrying bleeding patterns reduced satisfaction. Counselling of women may address some of these problems since it provides reassurance and reduces anxiety. In settings that lack adequate staffing levels of physicians or where midwives are available to provide misoprostol, task sharing second trimester medical PAC with midwives increases patient’s access to PAC services.

Evaluating the safety, effectiveness and acceptability of treatment of incomplete second-trimester abortion using misoprostol provided by midwives compared with physicians: study protocol for a randomized controlled equivalence trial

BACKGROUND

A large proportion of abortion-related mortality and morbidity occurs in the second trimester of pregnancy. The Uganda Ministry of Health policy restricts management of second-trimester incomplete abortion to physicians who are few and unequally distributed, with most practicing in urban regions. Unsafe and outdated methods like sharp curettage are frequently used. Medical management of second-trimester post-abortion care by midwives offers an advantage given the difficulty in providing surgical management in low-income settings and current health worker shortages. The study aims to assess the safety, effectiveness and acceptability of treatment of incomplete second-trimester abortion using misoprostol provided by midwives compared with physicians.

METHODS

A randomized controlled equivalence trial implemented at eight hospitals and health centers in Central Uganda will include 1192 eligible women with incomplete abortion of uterine size > 12 weeks up to 18 weeks. Each participant will be randomly assigned to undergo a clinical assessment and treatment by either a midwife (intervention arm) or a physician (control arm). Enrolled participants will receive 400 μg misoprostol administered sublingually every 3 h up to five doses within 24 h at the health facility until a complete abortion is confirmed. Women who do not achieve complete abortion within 24 h will undergo surgical uterine evacuation. Pre discharge, participants will receive contraceptive counseling and information on what to expect in terms of side effects and signs of complications, with follow-up 14 days later to assess secondary outcomes. Analyses will be by intention to treat. Background characteristics and outcomes will be presented using descriptive statistics. Differences between groups will be analyzed using risk difference (95% confidence interval) and equivalence established if this lies between the predefined range of - 5% and + 5%. Chi-square tests will be used for comparison of outcome and t tests used to compare mean values. P ≤ 0.05 will be considered statistically significant.

DISCUSSION

Our study will provide evidence to inform national and international policies, standard care guidelines and training program curricula on treatment of second-trimester incomplete abortion for improved access.

Medical treatment of second-trimester fetal miscarriage; A retrospective analysis

OBJECTIVES

Research on the treatment of second-trimester miscarriages is scarce. We studied the outcomes, and the factors associated with adverse events and need for hospital resources in the medical treatment of second-trimester miscarriage.

MATERIALS AND METHODS

In these retrospective analyses we studied women treated for spontaneous fetal miscarriage with misoprostol-only (n = 24) or mifepristone and misoprostol (n = 177) in duration of gestation 12+1-21+6. Primary outcomes were the risk factors for surgical evacuation and excessive bleeding. Secondary outcomes were total misoprostol dose, time to expulsion and the length of hospital stay.

RESULTS

History of surgical evacuation of the uterus increased the risk of surgical evacuation (p = 0.027). Excessive bleeding was not associated with any of the studied variables. More misoprostol was needed when the duration of gestation exceeded 17+0 weeks (p = 0.036). In multivariate analysis the time to fetal expulsion was shorter in women with history of 1-2 deliveries (hazard ratio [HR] 1.49, 95% confidence interval [CI]; 1.07-2.07), ≥3 deliveries (HR 1.63, 95% CI; 1.11-2.38) and with a two-day interval between mifepristone-misoprostol administration (HR 1.71, 95% CI; 1.05-2.81). Patients with symptoms (i.e. uterine bleeding or pain) at baseline had longer hospital stay (HR 0.66, 95% CI; 0.47-0.92).

CONCLUSIONS

The factors affecting the outcomes of medical treatment of second-trimester fetal miscarriage are similar to those of second-trimester induced abortion. Two-day interval between mifepristone-misoprostol administration might decrease the time to fetal expulsion and the need of hospital resources.
