RESUMEN
BACKGROUND: Patients with obesity experience an increased duration of labor with an increased risk for perinatal morbidity. When compared with parturients without obesity, they also experience fewer uterine contractions after administration of misoprostol. It is unclear if the same dose of misoprostol should be used for induction of labor in patients with obesity compared to non-obese patients. Therefore, we sought to investigate if a higher dose of misoprostol for patients with obesity is more effective. OBJECTIVE: This study aimed to determine if 50 µg compared with 25 µg of vaginal misoprostol reduced the time from induction start to delivery among patients with obesity. STUDY DESIGN: We performed a double-blinded, pragmatic randomized controlled trial, between June 1, 2022, and July 17, 2023. Patients with a body mass index ≥30 kg/m2 who underwent labor induction at ≥ 36 weeks' gestation, had a singleton gestation, and a cervical dilation ≤3 cm at admission were included. Patients were excluded if they had a contraindication to vaginal delivery or misoprostol administration. Patients were randomized to 25 or 50 µg of vaginal misoprostol, stratified by parity, body mass index <40 kg/m2 or ≥40 kg/m2, and provider intent to use mechanical dilation at the onset of labor induction. Usual labor management was followed at the discretion of the provider. The primary outcome was time from induction to delivery. A priori, we estimated that 90 subjects per group (N=180) were needed for an 85% power to detect a 3-hour difference between groups with a type I error of 5%. Analysis was by intention-to-treat. A 2-sample t test was used for the primary outcome, Cohen's d was used as a measure of effect, and P values were reported. RESULTS: Of the 180 patients randomized, 88 were assigned to the 25 µg group and 92 were assigned to the 50 µg group. Of those, 96.1% of patients received the designated intervention. The baseline characteristics were similar between groups. No difference was found in the primary outcome of time to delivery (21.6 hours vs 18.6 hours; d=.28; 95% confidence interval, -0.02 to 0.57). In a planned subgroup analysis, multiparous patients delivered faster in the 50 µg group (15.2 hours vs 12.0 hours; d=.51; 95% confidence interval, 0.04-0.97). The risk for tachysystole associated with fetal heart tracing changes was rare overall (2.2%) and not significantly different between groups. No differences in maternal or neonatal adverse effects were observed. CONCLUSION: Patients with obesity who underwent cervical ripening with 50 µg of vaginal misoprostol experienced a similar time to delivery when compared with those who received 25 µg of misoprostol. However, multiparous patients had a significantly reduced time to delivery when 50 µg was used. A higher dose of misoprostol may be a promising intervention for reducing time in labor, which warrants further study.

BACKGROUND: Induction of labour (IOL) is common practice and different methods carry different effectiveness and safety profiles. OBJECTIVES: To compare the effectiveness, and maternal and perinatal safety outcomes of IOL with vaginal misoprostol versus vaginal dinoprostone using individual participant data from randomised clinical trials. SEARCH STRATEGY: The following databases were searched from inception to March 2023: CINAHL Plus, ClinicalTrials.gov, Cochrane Pregnancy and Childbirth Group Trial Register, Ovid Embase, Ovid Emcare, Ovid MEDLINE, Scopus and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). SELECTION CRITERIA: Randomised controlled trials (RCTs), with viable singleton gestation, no language restrictions, and all published and unpublished data. DATA COLLECTION AND ANALYSIS: An individual participant data meta-analysis was carried out. MAIN RESULTS: Ten of 52 eligible trials provided individual participant data, of which two were excluded after checking data integrity. The remaining eight trials compared low-dose vaginal misoprostol versus dinoprostone, including 4180 women undergoing IOL, which represents 32.8% of all participants in the published RCTs. Of these, 2077 were assigned to low-dose vaginal misoprostol and 2103 were assigned to vaginal dinoprostone. Compared with vaginal dinoprostone, low-dose vaginal misoprostol had a comparable rate of vaginal birth. Composite adverse perinatal outcomes did not differ between the groups. Compared with vaginal dinoprostone, composite adverse maternal outcomes were significantly lower with low-dose vaginal misoprostol (aOR 0.80, 95% CI 0.65-0.98, P = 0.03, I2 = 0%). CONCLUSIONS: Low-dose vaginal misoprostol and vaginal dinoprostone for IOL are comparable in terms of effectiveness and perinatal safety. However, low-dose vaginal misoprostol is likely to lead to a lower rate of composite adverse maternal outcomes than vaginal dinoprostone.

INTRODUCTION: Labor induction rates have increased over the last decades, and in many high-income countries, more than one in four labors are induced. Outpatient management of labor induction has been suggested in low-risk pregnancies to improve women's birth experiences while also promoting a more efficient use of healthcare resources. The primary aim of this paper was to assess the proportion of women in a historical cohort that would have been eligible for outpatient labor induction with oral misoprostol. Second, we wanted to report safety outcomes and assess efficacy outcomes for mothers and infants in pregnancies that met the criteria for outpatient care. MATERIAL AND METHODS: Criteria for outpatient labor induction with oral misoprostol were applied to a historical cohort of women with induction of labor at two Norwegian tertiary hospitals in the period January 1, through July 31, 2021. The criteria included low-risk women with an unscarred uterus expecting a healthy, singleton baby in cephalic position at term. The primary outcome was the proportion of women eligible for outpatient labor induction. Secondary outcomes included reasons for ineligibility and, for eligible women, safety and efficacy outcomes. RESULTS: Overall, 29.7% of the 1320 women who underwent labor induction in a singleton term pregnancy met the criteria for outpatient labor induction. We identified two serious adverse events that potentially could have occurred outside the hospital if the women had received outpatient care. The mean duration from initiation of labor induction to administration of the last misoprostol was 22.4 h. One in 14 multiparous women gave birth within 3 h after the last misoprostol dose. CONCLUSIONS: In this historical cohort, three in ten women met the criteria for outpatient management of labor induction with oral misoprostol. Serious adverse events were rare. The average time span from the initiation of labor induction to the last misoprostol was nearly 24 h. This suggests a potential for low-risk women with an induced labor to spend a substantial period of time at home before labor onset. However, larger studies testing or evaluating labor induction with oral misoprostol as an outpatient procedure are needed to draw conclusions.

BACKGROUND: However, misoprostol is often used to terminate a pregnancy, but it can also cause side effects. Isosorbide mononitrate (ISMN) can help the cervix mature by increasing the production of prostaglandin E2 and vasodilation. Considering that the results of studies in this field are contradictory, it is the purpose of this study to evaluate the efficacy and safety of vaginal ISMN plus misoprostol compared to misoprostol alone in the management of first- and second-trimester abortions. METHOD: The search process was conducted for MEDLINE through the PubMed interface, Scopus, Web-of-Science, Science Direct, the Cochrane Central Register of Controlled Trials (CENTRAL), Google Scholar, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform until November 10, 2023. Our assessment of bias was based on version 2 of the risk-of-bias tool (RoB2) for randomized trials and our level of evidence quality was determined by GRADE. Meta-analysis of all data was carried out using Review Manager (RevMan) version 5.1. RESULT: Seven randomized clinical trials were included in the systematic review and three in the meta-analysis, with mixed quality. The results of the meta-analysis revealed that in the second-trimester abortion, the inclusion of ISMN in conjunction with vaginal misoprostol results in a noteworthy reduction in the induction abortion interval, specifically by 4.21 h (95% CI: -7.45 to -0.97, P = 0.01). The addition of vaginal ISMN to misoprostol, compared to vaginal misoprostol alone, increased the odds of a completed abortion by 3.76 times. (95% CI: 1.08 to 13.15, P = 0.04). CONCLUSION: The findings of this study can offer valuable insights aimed at enhancing counseling and support for non-surgical methods of medication abortion within professional settings. Moreover, it improves the effectiveness of clinical treatment and reduces the occurrence of unnecessary surgical interventions in the abortion management protocol.

OBJECTIVES: To evaluate the safety and efficacy of first-trimester "No Touch" medication abortion programs at 2 clinics in Toronto, Ontario during their early implementation in response to the COVID-19 pandemic. METHODS: This retrospective study included all patients who underwent virtual consultation for mifepristone-misoprostol medication abortion between April 2020-August 2022 at 2 reproductive health clinics. In response to the pandemic, "No Touch" abortion protocols have been developed that align with the Canadian Protocol for the Provision of Medical Abortion via Telemedicine. Records were reviewed for demographic information, clinical course, investigations required, confirmation of complete abortion and adverse events. The primary outcome was complete medication abortion, defined as expulsion of the pregnancy without requiring uterine aspiration. RESULTS: A total of 277 patients had abortions initiated in the "No Touch" or "Low Touch" care pathways and had sufficient follow-up to determine outcomes. Of these patients, 92.8% (95% CI 89.7%-95.8%) had a complete medication abortion (n = 257) and 76.1% (n = 159) remained "No Touch" throughout their care. Investigations were performed for 102 participants before or after their abortion, classifying them as "Low Touch". Nineteen patients (6.9%) underwent uterine aspiration. The rate of adverse events was low, with 1 case of a missed ectopic pregnancy and 1 patient requiring hospitalization for endometritis. CONCLUSIONS: "No Touch" provision of mifepristone-misoprostol medication abortion care was safe and effective with outcomes comparable to previous studies. These results provide evidence for the efficacy and safety of a "No Touch" approach in the Canadian context, which has the potential to reduce barriers to accessing abortion care.

BACKGROUND: In 2006, a Constitutional Court ruling partially decriminalized abortion in Colombia, allowing the procedure in cases of rape, risk to the health or life of the woman, and fetal malformations incompatible with life. Despite this less prohibitive law, some women and pregnant people preferred self-managing their abortions outside the formal healthcare system, often without accurate information. In 2018, we undertook a study to understand what motivated women to self-manage using medications that they acquired informally. Colombia has since adopted a progressive law in 2022, permitting abortion on request through the 24th week of pregnancy. However, the implementation of this law is still underway. Examining the reasons why women chose to informally self-manage an abortion after 2006 may not only highlight how barriers to legal services persisted at that time, but also could inform strategies to increase knowledge of the current abortion law and improve access to services going forward. METHODS: In-depth interviews were conducted in 2018 with 47 women aged 18 and older who used misoprostol obtained outside of health facilities to induce an abortion, and who were receiving postabortion care in two private clinics. Interviews explored what women knew about the 2006 abortion law which was then in effect, and the reasons why they preferred informal channels for abortion care over formal healthcare services. RESULTS: Women's motivations to use misoprostol obtained outside the formal healthcare system were influenced by lack of trust in the healthcare system along with incomplete and inaccurate knowledge of the abortion law. Conversely, women considered misoprostol obtained outside the healthcare system to be effective, affordable, and easier to access. CONCLUSIONS: Obtaining misoprostol outside the formal healthcare system offered a more accessible and appealing prospect for some women given fears of legal repercussion and stigma toward abortion. Though this preference will likely continue despite the more liberal abortion law, strategies should be implemented to broaden knowledge of the recent change in law and to combat misinformation and stigma. This would support knowledge of and access to legal abortion for those who wish to avail themselves of these services.

INTRODUCTION: Several studies have shown that late- and post-term pregnancies are associated with an increased risk of perinatal morbidity and mortality. In this case, induction of labor is the recommended approach. For full-term pregnancies, various methods exist to prepare the cervix and/or commence labor. Prostaglandins serve the dual purpose of cervical ripening and labor induction, blurring the distinction between the two processes. The aim of this research was to evaluate the effect of maternal age and body mass index (BMI) on oral misoprostol induction of labor for late-term pregnancies. METHODS: This was a retrospective cross-sectional study (ClinicalTrial ID: NCT06184139), including only late-term pregnancies in healthy nulliparous women carrying a single cephalic fetus with normal birthweight who underwent induction of labor with oral misoprostol. We used the oral misoprostol regimen proposed by the World Health Organization (WHO) for induction of labor in term singleton pregnancies in women who have not had a previous cesarean delivery and a Bishop score <7. The regimen was oral misoprostol in aqueous solution at the low dose of 25 µg every 2 h until a Bishop score ≥7, labor, or for a maximum of 8 doses. RESULTS: One hundred and four pregnant women underwent induction of labor with oral misoprostol for late-term pregnancy on the 290th day of gestation. Study population was divided in two groups based on age (<35 and ≥35 years) and obesity (BMI <30 and ≥30). No statistically significant differences were recorded between younger and older women. Obese women reported a longer time between the last dose of misoprostol and cervical dilation of 6 cm (p = 0.01), a longer time between the last dose of misoprostol and delivery (p = 0.04), and a higher rate of grade II vaginal lacerations (p = 0.02). CONCLUSIONS: Maternal BMI is a factor negatively influencing the efficacy of oral misoprostol for induction of labor in late-term pregnancy.

The U.S. FDA has permanently removed the in-person prescribing requirements that previously safeguarded the use of mifepristone/misoprostol medical abortions, allowing prescribing through telemedicine or on-line ordering and distribution through the mail and pharmacies, without standard pre-abortion testing. This will increase the risk of complications due to failure to adequately determine the gestational age or rule out ectopic pregnancy by ultrasound or physical exam, failure to perform labs to document whether RhoGAM is indicated, and failure to obtain appropriate informed consent to prevent unwanted abortions, among other concerns. The FDA justified this action by referencing flawed studies with significantly undercounted complications. The details of these study deficiencies are examined in this paper.

OBJECTIVE: To compare 24-hour and 12-hour mifepristone-to-misoprostol intervals for second-trimester medication abortion. METHODS: We conducted a prospective randomized controlled trial. Participants were allocated to receive mifepristone either 24 hours or 12 hours before misoprostol administration. The primary outcome was the time from the first misoprostol administration to abortion (induction time). Secondary outcomes included the time from mifepristone to abortion (total abortion time); fetal expulsion percentages at 12, 24, and 48 hours after the first misoprostol dose; side effects proportion; and pain and satisfaction scores. A sample size of 40 per group (N=80) was planned to compare the 24- and 12-hour regimens. RESULTS: Eighty patients were enrolled between July 2020 and June 2023, with 40 patients per group. Baseline characteristics were comparable between groups. Median induction time was 9.5 hours (95% CI, 10.3-17.8 hours) and 12.5 hours (95% CI, 13.5-20.2 hours) in the 24- and 12-hour interval arms, respectively ( P =.028). Median total abortion time was 33.0 hours (95% CI, 34.2-41.9 hours) and 24.5 hours (95% CI, 25.7-32.4 hours) in the 24- and 12-hour interval groups, respectively ( P <.001). At 12 hours from misoprostol administration, 25 patients (62.5%) in the 24-hour arm and 18 patients (45.0%) in the 12-hour arm completed abortion ( P =.178). At 24 hours from misoprostol administration, 36 patients (90.0%) in the 24-hour arm and 30 patients (75.0%) in the 12-hour arm had complete abortion ( P =.139). The need for additional medication or surgical treatment for uterine evacuation, pain scores, side effects, and satisfaction levels were not different between groups. CONCLUSION: A 24-hour mifepristone-to-misoprostol regimen for medication abortion in the second trimester provides a median 3-hour shorter induction time compared with the 12-hour interval. However, the median total abortion time was 8.5-hours longer in the 24-hour interval regimen. These findings can aid in shared decision making before medication abortion in the second trimester. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT04160221.

BACKGROUND: Misoprostol treatment for early pregnancy loss has varied success demonstrated in previous studies. Incorporating predictors in a single clinical scoring system would be highly beneficial in clinical practice. OBJECTIVE: To develop and evaluate the accuracy of a scoring system to predict misoprostol treatment outcomes for managing early pregnancy loss. STUDY DESIGN: Retrospective cohort and validation study. METHODS: Patients discharged from the gynecologic emergency department from 2013 to 2016, diagnosed with early pregnancy loss, who were treated with 800 mcg misoprostol, administrated vaginally were included. All were sonographically reevaluated within 48-72 hours. Patients in whom the gestational sac was not expelled or with endometrial lining >30 mm were offered a repeat dose and returned for reevaluation after seven days. A successful response was defined as complete expulsion. Clinical data were reviewed to identify predictors for successful responses. The scoring system was then retrospectively evaluated on a second cohort to evaluate its accuracy. Multivariate logistic regression was performed to identify factors most predictive of treatment response. RESULTS: The development cohort included 126 patients. Six factors were found to be most predictive of misoprostol treatment effectiveness: nulliparity, prior complete spontaneous abortion, gestational age, vaginal bleeding, abdominal pain, and mean sac diameter, yielding a score of 0-8 (the MISOPRED score), where 8 represents the highest-likelihood of success. The score was validated retrospectively with 119 participants. Successful response in the group with the lowest likelihood score (score 0-3) was 9%, compared with 82% in the highest likelihood score group (score 7-8). Using the MISOPRED score, approximately 15% of patients previously planned to receive misoprostol treatment can be referred for surgical management. CONCLUSIONS: MISOPRED score can be utilized as an adjunct tool for clinical decision-making in cases of Early pregnancy loss. To our knowledge, this is the first scoring system suggested to predict the success rate in these cases.

OBJECTIVE: The aim of this study was to evaluate the success rate and predictors of labor induction using vaginal misoprostol in a low-risk pregnant women population. METHODS: A prospective cohort study was carried out with 196 pregnant women. Groups 2 and 4 of the Robson Classification admitted for induction of labor with vaginal misoprostol (25 µg tablets every 6 h, up to 4 tablets, for a maximum of 24 h). The success of labor induction was considered the achievement of vaginal delivery. Binary logistic regression was used to determine the best predictors of successful induction of labor with vaginal misoprostol. RESULTS: Of all the pregnant women analyzed, 140 (71.4%) were successful and 56 (28.6%) were unsuccessful. Pregnant women who achieved successful induction had a higher number of pregnancies (1.69 vs. 1.36, p=0.023), a higher number of deliveries (0.57 vs. 0.19, p<0.001), a higher Bishop score (2.0 vs. 1.38, p=0.002), and lower misoprostol 25 µg tablets (2.18 vs. 2.57, p=0.031). No previous deliveries [x2(1)=3.14, odds ratio (OR): 0.24, 95% confidence interval (CI): 0.10-0.57, R2 Nagelkerke: 0.91, p=0.001] and the presence of one previous delivery [x2(1)=6.0, OR: 3.40, 95% CI: 1.13-10.16, R2 Nagelkerke: 0.043, p=0.029] were significant predictors of successful induction of labor with vaginal misoprostol. CONCLUSION: A high rate of labor induction success using vaginal misoprostol in a low-risk population was observed, mainly in multiparous and with gestational age>41 weeks. No previous delivery decreased the success of labor induction, while one previous delivery increased the success of labor induction.

Importance: Before 2021, the US Food and Drug Administration required mifepristone to be dispensed in person, limiting access to medication abortion. Objective: To estimate the effectiveness, acceptability, and feasibility of dispensing mifepristone for medication abortion using a mail-order pharmacy. Design, Setting, and Participants: This prospective cohort study was conducted from January 2020 to May 2022 and included 11 clinics in 7 states (5 abortion clinics and 6 primary care sites, 4 of which were new to abortion provision). Eligible participants were seeking medication abortion at 63 or fewer days' gestation, spoke English or Spanish, were age 15 years or older, and were willing to take misoprostol buccally. After assessing eligibility for medication abortion through an in-person screening, mifepristone and misoprostol were prescribed using a mail-order pharmacy. Patients had standard follow-up care with the clinic. Clinical information was collected from medical records. Consenting participants completed online surveys about their experiences 3 and 14 days after enrolling. A total of 540 participants were enrolled; 10 withdrew or did not take medication. Data were analyzed from August 2022 to December 2023. Intervention: Mifepristone, 200 mg, and misoprostol, 800 µg, prescribed to a mail-order pharmacy and mailed to participants instead of dispensed in person. Main Outcomes and Measures: Proportion of patients with a complete abortion with medications only, reporting satisfaction with the medication abortion, and reporting timely delivery of medications. Results: Clinical outcome information was obtained and analyzed for 510 abortions (96.2%) among 506 participants (median [IQR] age, 27 [23-31] years; 506 [100%] female; 194 [38.3%] Black, 88 [17.4%] Hispanic, 141 [27.9%] White, and 45 [8.9%] multiracial/other individuals). Of these, 436 participants (85.5%; 95% CI, 82.2%-88.4%) received medications within 3 days. Complete abortion occurred after medication use in 499 cases (97.8%; 95% CI, 96.2%-98.9%). There were 24 adverse events (4.7%) for which care was sought for medication abortion symptoms; 3 patients (0.6%; 95% CI, 0.1%-1.7%) experienced serious adverse events requiring hospitalization (1 with blood transfusion); however, no adverse events were associated with mail-order dispensing. Of 477 participants, 431 (90.4%; 95% CI, 87.3%-92.9%) indicated that they would use mail-order dispensing again for abortion care, and 435 participants (91.2%; 95% CI, 88.3%-93.6%) reported satisfaction with the medication abortion. Findings were similar to those of other published studies of medication abortion with in-person dispensing. Conclusions and Relevance: The findings of this cohort study indicate that mail-order pharmacy dispensing of mifepristone for medication abortion was effective, acceptable to patients, and feasible, with a low prevalence of serious adverse events. This care model should be expanded to improve access to medication abortion services.

In January 2023, the Food & Drug Administration modified the Risk Evaluation and Mitigation Strategy program regulating mifepristone to allow direct dispensation from retail pharmacies. In June 2023, we conducted a random, distributive survey of pharmacies in California using secret shopper methodology to investigate the feasibility of accessing mifepristone. One pharmacy had mifepristone immediately available (<24 hours), and misoprostol availability was limited. Accessibility to misoprostol varied by type of pharmacy (p < 0.01), but not by region. Even in a reproductive freedom state, access to mifepristone and misoprostol from outpatient retail pharmacies remains limited.

OBJECTIVES: This study aimed to describe the same-day availability of misoprostol for medical management of early pregnancy loss (EPL) at Arizona pharmacies. STUDY DESIGN: We performed a simulated-patient mixed methods study of Arizona pharmacies from October 2022 to February 2023, documenting misoprostol availability and describing pharmacy staff responses. RESULTS: Of 941 pharmacies included, 703 (75%) could fill a misoprostol prescription same day. Ability to fill prescriptions and reasons why the prescription could not be filled varied by pharmacy type. National chain pharmacies most frequently had misoprostol available but also most commonly reported policies restricting dispensing. CONCLUSIONS: Barriers exist to filling misoprostol prescriptions for early pregnancy loss in Arizona that could impact patient care.

Objective: To compare cervical ripening time with the use of vaginal Misoprostol plus Hyoscine-N-Butylbromide, with vaginal Misoprostol alone. Design: A double-blind randomized controlled trial with Pan-African Clinical Trials Registry (PACTR) approval number PACTR202112821475292. Setting: Federal Medical Centre, Asaba, Nigeria. Participants: A total of 126 eligible antenatal patients for cervical ripening were enrolled. Interventions: Participants in Group A had 25µg of vaginal misoprostol with 1ml of intramuscular placebo, and those in Group B had 25µg of vaginal misoprostol with 20mg of Intramuscular Hyoscine (1 ml). Oxytocin infusion was used when indicated, and the labour was supervised as per departmental protocol. Main outcome measure: Cervical ripening time. Results: The mean cervical ripening time was statistically significantly shorter in the hyoscine group (8.48±4.36 hours) than in the placebo group (11.40±7.33 hours); p-value 0.02, 95% CI 0.80-5.05. There was no statistically significant difference in the mean induction-delivery interval in Group A (7.38±5.28 hours) compared to Group B (7.75±5.04 hours), with a value of 0.54. The mode of delivery was comparable. However, women in Group B (53, 84.1%) achieved more vaginal deliveries than women in Group A (50, 79.4%); p-value 0.49. Thirteen women in Group A (20.6%) had a caesarean section, while ten women (15.9%) in Group B had a caesarean section (p-value 0.49, RR 0.94, CI 0.80-1.11). Adverse maternal and neonatal outcomes were not statistically significant between the two groups. Conclusion: Intramuscular hyoscine was effective in reducing cervical ripening time when used as an adjunct to vaginal Misoprostol, with no significant adverse maternal or neonatal outcome. Funding: None declared.

OBJECTIVES: To evaluate the implementation of mifepristone and misoprostol for medical management of early pregnancy loss (EPL) in emergency departments (EDs) by comparing efficacy, complication, and follow-up rates for patients treated in EDs to the Complex Family Planning (CFP) outpatient office. STUDY DESIGN: In COVID-19's first wave, we expanded medical management of EPL to our EDs. This retrospective study evaluated 72 patients receiving mifepristone and misoprostol for EPL from April 1, 2020 to March 31, 2021, comparing treatment success, safety outcomes, and follow-up rates by location. RESULTS: Thirty-three (46%) patients received care in the ED and 39 (54%) at CFP. Treatment success was lower in EDs (23, 70%) compared to CFP (34, 87%), but after adjusting for insurance status and pregnancy type (miscarriage, uncertain viability, unknown location), this was not significant: adjusted odds ratio 0.48 (95% CI 0.13-1.81). More ED patients underwent emergent interventions (3 vs 0) including two emergent uterine aspirations, one uterine artery embolization, and two blood transfusions. Two cases were attributed to misdiagnosis (cesarean scar and cervical ectopic pregnancies interpreted as incomplete miscarriages) and one to guideline nonadherence. No complications occurred in the CFP group. Follow-up rates were over 80% in both groups. More ED patients engaged in telehealth follow-up (67% vs 18%, p ≤ 0.0001). CONCLUSIONS: In this small sample, we observed a trend toward less successful treatment in the ED compared to the CFP office. Both correctly making uncommon diagnoses and adhering to new guidelines presented implementation challenges. IMPLICATIONS: Implementing mifepristone and misoprostol for EPL in our EDs achieved lower rates of pregnancy resolution compared to outpatient management. Complex uncommon diagnoses and implementing new care pathways in EDs may have contributed to complications and highlighted opportunities for improvement. Additional studies are needed to further quantify safety outcomes for EPL management in EDs.

BACKGROUND: The Maternal and Perinatal Death Surveillance and Response (MPDSR) was introduced in Kenya in 2016 and implemented at Kiambu Level 5 Hospital (KL5H) three years later in 2019. During a routine MPDSR meeting at KL5H, committee members identified a possible link between the off-label use of 200mcg misoprostol tablets divided eight times to achieve the necessary dose for labour induction (25mcg) and maternal deaths. Following this, an administrative decision was made to switch from misoprostol to dinoprostone for the induction of labour in June of 2019. This study aimed to assess the overall impact of MPDSR as well as the effect of replacing misoprostol with dinoprostone on uterine rupture, maternal and neonatal deaths at KL5H. METHODS: We conducted a retrospective cohort study of women who gave birth at KL5H between January 2018 and December 2020. We defined the pre-intervention period as January 2018-June 2019, and the intervention period as July 2019-December 2020. We randomly selected the records of 411 mothers, 167 from the pre-intervention period and 208 from the intervention period, all of whom were induced. We used Bayes-Poisson Generalised Linear Models to fit the risk of uterine rupture, maternal and perinatal death. 12 semi-structured key person questionnaires was used to describe staff perspectives regarding the switch from misoprostol to dinoprostone. Inductive and deductive data analysis was done to capture the salient emerging themes. RESULTS: We reviewed 411 patient records and carried out 12 key informant interviews. Mothers induced with misoprostol (IRR = 3.89; CI = 0.21-71.6) had an increased risk of death while mothers were less likely to die if they were induced with dinoprostone (IRR = 0.23; CI = 0.01-7.12) or had uterine rupture (IRR = 0.56; CI = 0.02-18.2). The risk of dying during childbearing increased during Jul 2019-Dec 2020 (IRR = 5.43, CI = 0.68-43.2) when the MPDSR activities were strengthened. Induction of labour (IRR = 1.01; CI = 0.06-17.1) had no effect on the risk of dying from childbirth in our setting. The qualitative results exposed that maternity unit staff preferred dinoprostone to misoprostol as it was thought to be more effective (fewer failed inductions) and safer, regardless of being more expensive compared to misoprostol. CONCLUSION: While the period immediately following the implementation of MPDSR at KL5H was associated with an increased risk of death, the switch to dinoprostone for labour induction was associated with a lower risk of maternal and perinatal death. The use of dinoprostone, however, was linked to an increased risk of uterine rupture, possibly attributed to reduced labour monitoring given that staff held the belief that it is inherently safer than misoprostol. Consequently, even though the changeover was warranted, further investigation is needed to determine the reasons behind the rise in maternal mortalities, even though the MPDSR framework appeared to have been put in place to quell such an increase.

AbstractWith recent severe restrictions to abortion accessibility in the United States and a pending Supreme Court case challenging the Food and Drug Administration's approval of mifepristone, evidence-based strategies to protect and expand access to abortion care are needed. Two safe and effective regimens for medication abortion are widely used globally - misoprostol-only and misoprostol in combination with mifepristone. However, misoprostol-only regimens are rarely used in the United States. In 2023, the National Abortion Federation and the Society of Family Planning updated their recommended protocol for misoprostol-only for medication abortion to 800 µg of misoprostol administered buccally, sublingually, or vaginally every 3 hours for three or more doses. To characterize the data supporting this specific regimen, this article reviews the relevant literature to address the question of how effective misoprostol-only is for medication abortion. The authors conclude that the updated misoprostol regimen is highly effective and a potential strategy for expanding access to abortion.

OBJECTIVE: To compare the success rates of medical management using a combined mifepristone and misoprostol protocol in cases of early pregnancy loss (EPL) between women who conceived without medical assistance and those who conceived through in vitro fertilization (IVF), after fresh or frozen embryo transfer, and evaluate for the predictive factors of success, time to first passage of tissue, and time to complete resolution of pregnancy. DESIGN: Retrospective cohort study. SETTING: University hospital. PATIENT(S): Women who presented with EPL below 13 weeks of gestation between June 2013 and July 2021 who were managed medically with mifepristone 200 mg orally and misoprostol 800 mcg vaginally were included in the study. INTERVENTION(S): Medical management with mifepristone and misoprostol; conception without medical assistance vs. post-IVF, after fresh or frozen embryo transfer. MAIN OUTCOME MEASURE(S): We evaluated overall success and performed subgroup analysis according to the mode of conception and compared fresh vs. frozen-thawed embryo transfers for IVF pregnancies. In all groups, we also calculated success according to gestational age and compared the time to first passage of tissue. The potential predictive factors of treatment success were analyzed. The side effects and complications of treatment were recorded. RESULT(S): A total of 930 women were included in the study, 99 (11%) of whom achieved pregnancy after IVF. The overall success of medical treatment was 89% with no statistically significant difference according to the mode of conception (89% vs. 89%) or type of transfer (fresh 89% vs. frozen 89%). Only lower gestational age by sonography was independently predictive of treatment success, showing a negative regression coefficient of ß = -0.333 and an odds ratio of 0.717. The mean time to first passage of tissue was 5.0 ± 2.1 hours. Altogether, 666 women (72%) showed pregnancy resolution on the day of medication administration, an additional 110 women at 1-week follow-up, and a further 74 women after ≥4 weeks on ultrasound. CONCLUSION(S): Medical management of EPL with mifepristone and misoprostol is a highly successful treatment option that results in completed abortion in a timely fashion in both pregnancies conceived without medical assistance and those conceived after IVF.
