Effectiveness and safety of misoprostol-only for first-trimester medication abortion: An updated systematic review and meta-analysis.

OBJECTIVES: This study aimed to update our 2019 systematic review of data on the effectiveness and safety of misoprostol-only for first-trimester abortion. STUDY DESIGN: We searched PubMed on December 18, 2022, to find published articles describing the outcomes of treatment with misoprostol-only for abortion of viable intrauterine pregnancy at ≤91 days of gestation. From each article identified, two authors independently abstracted relevant data about each group of patients treated with a distinct regimen. We assessed the risk of bias using four defined indicators. We estimated the proportion of patients with treatment failure using meta-analytic methods as well as the proportion hospitalized or transfused after treatment. We examined associations between treatment failure and selected characteristics of the groups. RESULTS: We identified 49 papers with 66 groups that collectively included 16,354 evaluable patients, of whom 2960 (meta-analytic estimate 15%, 95% CI 12%, 19%) had treatment failures. Of 9228 patients assessed for ongoing pregnancy after treatment, 521 (meta-analytic estimate 6%, 95% CI 5%, 8%) had that condition. Failure risk was significantly associated with misoprostol dose, the total allowed number of doses, the maximum duration of dosing, and certain indicators of risk of bias. Among 11,007 patients allowed to take at least three misoprostol doses, the first consisting of misoprostol 800 mcg administered vaginally, sublingually, or buccally, the meta-analytic estimate of the failure risk was 11% (95% CI 8%, 14%). At most, 0.2% of 15,679 evaluable patients were hospitalized or received transfusions. CONCLUSIONS: Although some studies in this updated review were adjudicated to have a high risk of bias, the results continue to support the key conclusion of our 2019 analysis: misoprostol-only is effective and safe for the termination of first-trimester intrauterine pregnancy. IMPLICATIONS: Misoprostol-only is a safe and effective option for medication abortion in the first trimester if mifepristone is unavailable or inaccessible.

Clinical outcomes of medication abortion using misoprostol-only: A retrospective chart review at an abortion provider organization in the United States.

OBJECTIVES: This study aimed to evaluate the effectiveness and safety of medication abortion with misoprostol-only among patients treated by an abortion provider organization in the United States during the COVID-19 pandemic. STUDY DESIGN: We abstracted data from patients receiving misoprostol-only for abortion from December 2020 to December 2021. Two regimens were used, both allowing three to four doses of misoprostol 800 mcg every 3 hours but differing in the recommended administration routes (vaginal, buccal, or sublingual). We estimated the proportions of patients who had complete abortion and ongoing pregnancy in the two regimen groups in complete case analyses and after imputing missing outcomes based on pretreatment characteristics. We also estimated maximum effectiveness, assuming that all patients without known treatment failures had complete abortions. We tabulated serious adverse events. RESULTS: We ascertained abortion outcomes for 476 (52%) of the total 911 treated patients. Of the 476 patients, 389 (82%) had complete abortion confirmed by test or history, and 45 (9%) had ongoing pregnancies detected after the provision of treatment. These proportions did not differ significantly between the two regimen groups in adjusted complete case analyses (p > 0.44). The results of imputed analyses were similar. Of the total 911 patients, at most 90% (95% confidence interval 88%, 92%) had complete abortion, and at least 5% (95% confidence interval 4%, 7%) had ongoing pregnancy. Serious adverse events were reported in three patients (0.6% of 487 patients with data for this outcome). CONCLUSIONS: Our analysis suggests that the misoprostol-only regimens studied were safe and effective for most patients. Due to high loss to follow-up, observations from patients contacted after treatment likely somewhat underestimate true effectiveness. IMPLICATIONS: Medication abortion with misoprostol-only was safe and produced complete abortion in most patients with follow-up. If loss to follow-up is high, effectiveness observed by clinics may misestimate true treatment efficacy.

Self-managed abortion via the internet: Analysis of one year of service delivery data from Women Help Women.

Background: To better comprehend the demand for online medication abortion and to inform service delivery practice, we conducted an analysis of Women Help Women (WHW) service delivery statistics. The primary goals were to understand their user profile, evaluate self-reported outcomes and use of other medical services, and assess the overall experience both with the abortion itself and with the counseling and care provided by WHW. Methods: We retrospectively evaluated user characteristics, abortion outcomes, and acceptability of both the medication abortion and WHW's services, using consultation data and corresponding evaluation data from a one-year period. For users who did not complete the evaluation form, WHW staff reviewed email correspondences to identify key outcomes. Results: From August 2016-July 2017, 3,307 individuals received abortion pills from WHW. Users were geographically located in thirty countries and correspondence was conducted in seven languages. Most reported their gestational age to be less than eight weeks. Of the 2,295 who took the pills and provided outcome information, almost all (99.1%, n=2275) reported that they were no longer pregnant. The majority (84.1%, n=1576/1875) used symptoms to confirm outcome; one fourth (22.8%, n=428) sought an ultrasound and one sixth (18.0%, n=338) used urine and/or serum testing. One in eight users (12.6%, n=292/2317) reported seeking additional medical care after taking the abortion pills. Most (87.5%, n=1551/1773) reported being satisfied or very satisfied with the abortion. Conclusions: Our study confirms that self-managed abortion is a process that people can do safely and effectively with community support and without medical supervision. In the context of a global backlash against abortion rights, self-managed abortion is an integral part of a spectrum of options for abortion care that must be made available to all.

An examination of loss to follow-up and potential bias in outcome ascertainment in a study of direct-to-patient telemedicine abortion in the United States.

OBJECTIVES: To examine associations between factors associated with loss to follow-up and effectiveness in the TelAbortion project, which provided medication abortion by direct-to-patient telemedicine and mail in the United States. STUDY DESIGN: The study population for this descriptive analysis included abortions among participants enrolled in the TelAbortion study with data present in a web-based database tool from November 2018 to September 2021 who were mailed a medication package. The analysis included information on abortions across nine sites. In this analysis, we used generalized estimating equations to examine factors associated with loss to follow-up and effectiveness. RESULTS: Of the 1831 abortions included in this analysis, 1553 (84.8%) were classified as having complete follow-up and 278 (15.2%) were classified as lost to follow-up. In a multivariable analysis, factors significantly associated with loss to follow-up included history of medical abortion, education, gestational age, study site, and whether the TelAbortion was performed pre- or post-COVID-19 onset (p < 0.05). The rate of treatment failure (i.e., abortions resulting in continuing pregnancy or uterine evacuation) reported in this study was 5.1%. The only covariate associated with both loss to follow-up and treatment failure was higher gestational age. However, using gestational age to impute missing abortion outcomes did not substantially change the estimated failure rate. CONCLUSIONS: Abortions that were lost to follow-up differed substantially from those with complete follow-up, which could bias the effectiveness estimate. However, imputing outcomes based on available and appropriate pretreatment data did not substantially affect the estimate. This finding is encouraging, although it does not exclude the possibility of bias due to unmeasured factors. IMPLICATIONS: Significant differences between abortion cases with complete follow-up and those lost to follow-up provide insights into abortion cases that may be at a higher risk for being lost. The low treatment failure rate indicates that the telemedicine provision of medication abortion is effective.

Single dose letrozole and misoprostol for termination of pregnancy through 63 days' gestation: A pilot study.

OBJECTIVES: We conducted a pilot study to evaluate a single dose of letrozole 30 mg prior to misoprostol 800 mcg buccally for medication abortion STUDY DESIGN: We enrolled 40 participants seeking medication abortion up to 63 days' gestation at a site in Salt Lake City, UT. Participants received a single dose of letrozole 30 mg in-clinic followed 2 days later by misoprostol 800 mcg buccally at home. They took a second dose of misoprostol if they had no bleeding within 24 hours of the first. Participants returned 7 to 10 days later for assessment of abortion outcome and side effects RESULTS: Thirty-seven participants (93%) returned for follow-up and 2 (5%) went to another facility from which research staff obtained outcome data. Three-fourths (29/39, 74%, 95% CI: 60%-89%) had a complete abortion; 4 (10%, 95% CI: 0.3%-20%) had an incomplete abortion and opted for aspiration, and 6 (15%, 95% CI: 4%-27%) had an ongoing pregnancy. All subjects with follow-up reported taking the first dose of misoprostol. Ten (27%) took the second dose as well; only three did so due to no bleeding. Nineteen participants (51%) reported side effects after letrozole prior to misoprostol and two people (5%) rated these effects as severe. Side effects following misoprostol occurred in 33 participants (89%) and were as expected based on previous literature. No serious adverse events were reported CONCLUSION: A single dose of letrozole 30 mg followed by misoprostol had lower than desirable efficacy and does not warrant further study. IMPLICATIONS: A single dose of letrozole does not appear to be an effective adjunct to misoprostol for medication abortion.

Person-centered, high-quality care from a distance: A qualitative study of patient experiences of TelAbortion, a model for direct-to-patient medication abortion by mail in the United States.

CONTEXT: Direct-to-patient telemedicine abortion allows people to receive mifepristone and misoprostol for medication abortion in their home without requiring an in-person visit with a healthcare provider. This method has high efficacy and safety, but less is known about the person-centered quality of care provided with telemedicine. METHODS: We interviewed 45 participants from the TelAbortion study of direct-to-patient telemedicine abortion in the United States from January to July 2020. Semi-structured qualitative interviews queried their choices, barriers to care, expectations for care, actual abortion experience, and suggestions for improvement. We developed a codebook through an iterative, inductive process and performed content and thematic analyses. RESULTS: The experience of direct-to-patient telemedicine abortion met the person-centered domains of dignity, autonomy, privacy, communication, social support, supportive care, trust, and environment. Four themes relate to the person-centered framework for reproductive health equity: (1) Participants felt well-supported and safe with TelAbortion; (2) Participants had autonomy in their care which led to feelings of empowerment; (3) TelAbortion exceeded expectations; and (4) Challenges arose when interfacing with the healthcare system outside of TelAbortion. Participants perceived abortion stigma which often led them to avoid traditional care and experienced enacted stigma during encounters with non-study healthcare workers. CONCLUSION: TelAbortion is a high quality, person-centered care model that can empower patients seeking care in an increasingly challenging abortion context.

Efficacy of a low-sensitivity urine pregnancy test for identifying ongoing pregnancy after medication abortion at 64 to 70 days of gestation.

OBJECTIVES: We assessed whether a low-sensitivity pregnancy test is effective at identifying ongoing pregnancy after medication abortion at 64 to 70 days of gestation. STUDY DESIGN: From October 2018 to March 2020, we performed a prospective observational study of participants in England and Wales undergoing medication abortion. Participants were scheduled to return to the clinic 14 ± 3 days after mifepristone administration to perform a low-sensitivity pregnancy test (human chorionic gonadotropin threshold of 1000 mIU/mL) and symptom checklist, and state whether they thought the abortion was complete. Clinicians also assessed the low-sensitivity pregnancy test and performed an ultrasound to determine abortion status. We calculated the sensitivity, specificity, negative and positive predictive value of the low-sensitivity pregnancy test (with and without a symptom checklist) for detecting ongoing pregnancy. RESULTS: We enrolled 757 participants. Thirty-one did not progress to abortion and 558 (76.9%) completed follow-up. Most (79.6%) attended per-protocol; 22 (3.9%) attended earlier than 11 days and 92 (16.5%) later than 17 days. Thirteen participants (2.3%) had an ongoing pregnancy. The low-sensitivity pregnancy test correctly identified all the ongoing pregnancies (sensitivity = 100%; specificity = 84.8%; negative predictive value = 100%; positive predictive value = 13.5%). The symptom checklist alone had a sensitivity of 76.9% and a negative predictive value of 99.4% for identifying ongoing pregnancies. Participants and clinicians agreed on the interpretation of the low-sensitivity pregnancy test 94.6% of the time. CONCLUSIONS: Patient self-assessment of a low-sensitivity pregnancy test after medication abortion between 64- and 70 days' gestation has high sensitivity and negative predictive value for identification of ongoing pregnancy. IMPLICATIONS: Patients can be offered a low-sensitivity pregnancy test to assess for ongoing pregnancy after medication abortion up to 70 days of gestation thereby reducing the need for in-person visits. Services should be prepared to provide in-person assessments after positive or inconclusive results to ensure early identification of abortion complications.

Clinical and service delivery implications of omitting ultrasound before medication abortion provided via direct-to-patient telemedicine and mail in the U.S.

OBJECTIVES: To compare outcomes among patients who did or did not have pre-abortion ultrasound or pelvic exam before obtaining medication abortion (MA) via direct-to-patient telemedicine and mail. STUDY DESIGN: We analyzed data from participants screened for enrollment into the TelAbortion study at five sites from March 25 to September 15, 2020. We compared participants who had preabortion ultrasound or pelvic exam ("test-MA") to those who did not ("no-test MA"). Outcomes were: abortion not complete with pills alone (i.e., had procedure intervention or ongoing pregnancy), ongoing pregnancy separately, ectopic pregnancy, hospitalization and/or blood transfusion, and unplanned clinical encounters. We used propensity score weighting and multivariable logistic regression to adjust for baseline characteristics. RESULTS: Our analysis included 287 participants who had no-test MA and 125 who had test-MA. Abortion was not complete with pills alone in 16of 287 (5.6%) no-test MA patients compared to 2of 123 (1.9%) test-MA patients (adjusted risk difference [aRD] = 4.3%, 95% confidence interval [CI]: 1.4%-7.1%). No ectopic pregnancies were detected. Groups did not differ regarding hospitalization and/or blood transfusion (p = 0.76) or ongoing pregnancy diagnosis (p = 0.59). Unplanned clinical encounters were more common in no-test MA patients (35of 287, 12.5%) than test-MA patients (10of 125, 8.0%, aRD = 6.7%, 95% CI: 0.5%-13.1%). CONCLUSIONS: Compared to patients who had pre-abortion ultrasound, patients who had no-test MA via telemedicine were more likely to have abortions that were not complete with pills alone and/or unplanned clinical encounters. However, both no-test and test-MA patients had similar and very low rates of ongoing pregnancy and hospitalization or blood transfusion. IMPLICATIONS: Omitting pre-abortion ultrasound before provision of medication abortion via telemedicine does not appear to compromise safety or result in more ongoing pregnancies. However, compared to patients who have preabortion ultrasound, patients who do not have pre-abortion tests may be more likely to seek post-treatment care and have procedural interventions.

Expansion of a direct-to-patient telemedicine abortion service in the United States and experience during the COVID-19 pandemic.

OBJECTIVE: To present updated evidence on the safety, efficacy and acceptability of a direct-to-patient telemedicine abortion service and describe how the service functioned during the COVID-19 pandemic. STUDY DESIGN: We offered the study at 10 sites that provided the service in 13 states and Washington DC. Interested individuals obtained any needed preabortion tests locally and had a videoconference with a study clinician. Sites sent study packages containing mifepristone and misoprostol by mail and had remote follow-up consultations within one month by telephone (or by online survey, if the participant could not be reached) to evaluate abortion completeness. The analysis was descriptive. RESULTS: We mailed 1390 packages between May 2016 and September 2020. Of the 83% (1157/1390) of abortions for which we obtained outcome information, 95% (1103/1157) were completed without a procedure. Participants made 70 unplanned visits to emergency rooms or urgent care centers for reasons related to the abortion (6%), and 10 serious adverse events occurred, including 5 transfusions (0.4%). Enrollment increased substantially with the onset of COVID-19. Although a screening ultrasound was required, sites determined in 52% (346/669) of abortions that occurred during COVID that those participants should not get the test to protect their health. Use of urine pregnancy test to confirm abortion completion increased from 67% (144/214) in the 6 months prior to COVID to 90% (602/669) in the 6 months during COVID. Nearly all satisfaction questionnaires (99%, 1013/1022) recorded that participants were satisfied with the service. CONCLUSIONS: This direct-to-patient telemedicine service was safe, effective, and acceptable, and supports the claim that there is no medical reason for mifepristone to be dispensed in clinics as required by the Food and Drug Administration. In some cases, participants did not need to visit any facilities to obtain the service, which was critical to protecting patient safety during the COVID-19 pandemic. IMPLICATIONS: Medical abortion using telemedicine and mail is effective and can be safely provided without a pretreatment ultrasound. This method of service delivery has the potential to greatly improve access to abortion care in the United States.

"False positive" urine pregnancy test results after successful medication abortion.

OBJECTIVE: To examine the proportion of high-sensitivity urine pregnancy test (HSPT) results that were positive by time after successful medication abortion. STUDY DESIGN: We used data from an ongoing study that provides mifepristone and misoprostol for medication abortion by direct-to-patient telemedicine and mail. Providers evaluated abortion outcomes by patient interview and clinical tests per clinical judgment and participant preference. We identified all participants enrolled July 2016 to September, 2020 who had an HSPT result and no indication of viable pregnancy after treatment. We used logistic regression to examine the association between the timing of the initial post-treatment HSPT, gestational age, and the proportion of HSPTs that gave a positive result. RESULTS: Of the 472 participants in our analysis, 88 (19%) had positive initial HSPTs. The proportions that were positive at ≤20 days, 21 to 27 days, 28 to 34 days, and ≥35 days after mifepristone ingestion was 14 of 29 (48%), 15 of 58 (26%), 49 of 258 (19%), and 10 of 127 (8%), respectively (p < 0.001). Gestational age at mifepristone ingestion was not significantly related to positive HSPT results (p = 0.28). Multivariable logistic regression confirmed both findings and did not identify a statistically significant interaction between these variables. In the 67 participants who relied solely on further HSPTs to confirm abortion outcome, the median interval between the initial positive test and first negative test was 14 days. CONCLUSIONS: The proportion of participants with positive HSPTs declined with time after successful medication abortion. However, nearly one-fifth of participants with complete abortion had positive tests 4 weeks after treatment. IMPLICATIONS: HSPTs provide an inexpensive, convenient option for confirming success of medication abortion at home. However, a substantial minority of patients without ongoing pregnancy have positive HSPT results. Development of a symptom-based strategy for medication abortion outcome assessment without any confirmatory tests should be a priority.

Multi-level pregnancy test use for medical abortion follow-up after 63 days' gestation: Evidence from prenatal hCG data.

OBJECTIVE: To explore hCG patterns using multi-level urine pregnancy tests (MLPTs) among prenatal clients to evaluate the potential use of these tests for medical abortion follow-up after 63 days' gestation. STUDY DESIGN: Prenatal clients with gestations 9-12 weeks were asked to administer an MLPT weekly for three weeks. We evaluated change in hCG range over one- and two-week intervals. RESULTS: Our analysis included 121 clients. Over one-week intervals, 26.5-43.1% of participants had a drop in hCG range. The proportion with a decline after two-weeks was 42.0-48.3%. CONCLUSION: This follow-up strategy would not work in gestations beyond 63 days.

Feasibility of a hospital outpatient day procedure for medication abortion at 13-18 weeks gestation: Findings from Nepal.

OBJECTIVES: To evaluate the safety, acceptability and feasibility of a one-day outpatient medication abortion service at gestations 13-18 weeks. STUDY DESIGN: Open-label prospective study in which participants received mifepristone 200 mg orally to swallow at home or at the clinic followed 24 h later by misoprostol 400 mcg buccally. They presented to the outpatient clinic 24-48 h after mifepristone for misoprostol 400 mcg buccally every three hours (no maximum dose). The primary outcome was successful abortion without transfer to overnight inpatient care. Secondary outcomes included time to abortion from initial misoprostol dose, safety, additional interventions and side effects. RESULTS: We enrolled 230 women from December 2017 to November 2018. Approximately nine of ten (n = 206, 89.6%) achieved a successful abortion without transfer to overnight care. Twenty-four were transferred to overnight inpatient care; of these 18 were to manage a complication, five for incomplete abortion and two by choice. Among these 24, three women experienced an SAE. The median time to successful abortion from time of the first misoprostol dose was 7.2 h (range: 0.75-92.3), with an average of three misoprostol doses. Most participants expelled the fetus and the placenta at or around the same time; median time between fetal and placental expulsion was 15 minutes (range: 0-4.5 h). Fifteen participants (6.6%) received more than five misoprostol doses and were transferred to inpatient care. Administration of more than five doses of misoprostol was associated with nulliparity. Provision of antibiotics (27.9%, n = 64), manual removal of placenta (15.3%, n = 35), uterotonics (4.4%, n = 10) and surgical interventions (4.4%, n = 10) were also reported. About one in four participants experienced nausea, vomiting and chills; fever was infrequent (2.5%, n = 5). CONCLUSIONS: For gestations 13-18 weeks, an outpatient day process for medication abortion is safe, effective and feasible. IMPLICATIONS: Medication abortion in 13 - 18 weeks need not be limited to inpatient care; nine of ten cases can be managed as an outpatient day service.

Oral antihypertensive regimens (nifedipine retard, labetalol, and methyldopa) for management of severe hypertension in pregnancy: an open-label, randomised controlled trial.

BACKGROUND: Hypertension is the most common medical disorder in pregnancy, complicating one in ten pregnancies. Treatment of severely increased blood pressure is widely recommended to reduce the risk for maternal complications. Regimens for the acute treatment of severe hypertension typically include intravenous medications. Although effective, these drugs require venous access and careful fetal monitoring and might not be feasible in busy or low-resource environments. We therefore aimed to compare the efficacy and safety of three oral drugs, labetalol, nifedipine retard, and methyldopa for the management of severe hypertension in pregnancy. METHODS: In this multicentre, parallel-group, open-label, randomised controlled trial, we compared these oral antihypertensives in two public hospitals in Nagpur, India. Pregnant women were eligible for the trial if they were aged at least 18 years; they were pregnant with fetuses that had reached a gestational age of at least 28 weeks; they required pharmacological blood pressure control for severe hypertension (systolic blood pressure ≥160 mm Hg or diastolic blood pressure ≥110 mm Hg); and were able to swallow oral medications. Women were randomly assigned to receive 10 mg oral nifedipine, 200 mg oral labetalol (hourly, in both of which the dose could be escalated if hypertension was maintained), or 1000 mg methyldopa (a single dose, without dose escalation). Masking of participants, study investigators, and care providers to group allocation was not possible because of different escalation protocols in the study groups. The primary outcome was blood pressure control (defined as 120-150 mm Hg systolic blood pressure and 70-100 mm Hg diastolic blood pressure) within 6 h with no adverse outcomes. This study is registered with ClinicalTrials.gov, number NCT01912677, and the Clinical Trial Registry, India, number ctri/2013/08/003866. FINDINGS: Between April 1, 2015, and Aug 21, 2017, we screened 2307 women for their inclusion in the study. We excluded 1413 (61%) women who were ineligible, declined to participate, had impending eclampsia, were in active labour, or had a combination of these factors. 11 (4%) women in the nifedipine group, ten (3%) women in the labetalol group, and 11 (4%) women in the methyldopa group were ineligible for treatment (because they had only one qualifying blood pressure measurement) or had treatment stopped (because of delivery or transfer elsewhere). 894 (39%) women were randomly assigned to a treatment group and were included in the intention-to-treat analysis: 298 (33%) women were assigned to receive nifedipine, 295 (33%) women were assigned to receive labetalol, and 301 (33%) women were assigned to receive methyldopa. The primary outcome was significantly more common in women in the nifedipine group than in those in the methyldopa group (249 [84%] women vs 230 [76%] women; p=0·03). However, the primary outcome did not differ between the nifedipine and labetalol groups (249 [84%] women vs 228 [77%] women; p=0·05) or the labetalol and methyldopa groups (p=0·80). Seven serious adverse events (1% of births) were reported during the study: one (<1%) woman in the labetalol group had an intrapartum seizure and six (1%) neonates (one [<1%] neonate in the nifedipine group, two [1%] neonates in the labetalol group, and three [1%] neonates in the methyldopa group) were stillborn. No birth had more than one adverse event. INTERPRETATION: All oral antihypertensives reduced blood pressure to the reference range in most women. As single drugs, nifedipine retard use resulted in a greater frequency of primary outcome attainment than labetalol or methyldopa use. All three oral drugs-methyldopa, nifedipine, and labetalol-are viable initial options for treating severe hypertension in low-resource settings.

Could second-trimester medical abortion be offered as a day service? Assessing the feasibility of a 1-day outpatient procedure using pooled data from six clinical studies.

OBJECTIVES: Current service delivery models for second-trimester medical abortion typically include routine inpatient admission and overnight stays. To assess the feasibility of a day-service model, we evaluated outpatient administration of abortion medications and analyzed the proportion of clients who could avoid an overnight stay. We also examined additional key elements of medical abortion care to evaluate the practicality of this model. STUDY DESIGN: We pooled data from six clinical studies of second-trimester medical abortion conducted by Gynuity over the past 10 years. We include 868 individuals receiving mifepristone-misoprostol abortion between 13 and 22 weeks' gestation. RESULTS: At 8 h post misoprostol initiation, 309/521 (59.3%) participants at 13-18 weeks' gestation had a successful abortion; by 10 h, 382/521 (73.3%) were successful. Taking the mifepristone at home lowered neither the efficacy of the method nor satisfaction with the experience. Nonphysician providers played a significant role in the provision of care. Needed interventions were relatively rare; serious complications were very rare. CONCLUSIONS: Our findings support the provision of second-trimester medical abortion in a day-clinic setting, especially at ≤18 weeks' gestation. Such a model could increase access to quality care in many settings. IMPLICATIONS: Second-trimester medical abortion can safely and effectively be offered as a day service. Nonphysician providers are well suited to provide the majority of care. Developing guidelines for a 1-day model could increase access to quality care in many settings worldwide.

Low-sensitivity urine pregnancy testing to assess medical abortion outcome: A systematic review.

OBJECTIVE: The objective was to summarize data on the accuracy and acceptability of a strategy for identifying ongoing pregnancy after medical abortion treatment using a low-sensitivity pregnancy test (LSPT). STUDY DESIGN: We searched PubMed to identify studies that evaluated the use of a single posttreatment LSPT for detection of ongoing pregnancy after treatment with mifepristone and misoprostol. We extracted, assessed and summarized data from each study. RESULTS: We found 10 studies that evaluated 6 LSPTs with human chorionic gonadotropin detection thresholds of 1000, 1500 or 2000 mIU/mL. The three earliest studies compared the pregnancy test strategy to standard assessment in the same women; the sensitivity of a positive or invalid LSPT result for detecting ongoing pregnancy ranged from 67% to 100%. Three randomized trials found no significant difference in detection of ongoing pregnancy between the LSPT strategy and routine in-person follow-up. Four noncomparative studies found that of the 12 women who had ongoing pregnancies diagnosed after performing an LSPT, 8 (67%) had positive or invalid LSPT results. Across the 10 studies, 30 of the 59 total ongoing pregnancies (51%) were identified based on symptoms without a positive or invalid LSPT result. Women expressed satisfaction with the LSPT strategy. Risk of bias in the seven later studies was high. CONCLUSIONS: Despite their limitations, most studies showed that the LSPT strategy had moderate sensitivity for identifying ongoing pregnancy and can enable the majority of medical abortion patients to assess treatment outcome at home. However, the LSPT itself had a limited role in the detection of treatment failures in the studies. IMPLICATIONS STATEMENT: The LSPT strategy shows promise for reducing the need for in-person follow-up after medical abortion. A range of home-based options should be validated to meet the varied needs of women and abortion providers in diverse settings.

Results of a pilot study in the U.S. and Vietnam to assess the utility and acceptability of a multi-level pregnancy test (MLPT) for home monitoring of hCG trends after assisted reproduction.

BACKGROUND: To evaluate the utility and acceptability of using multi-level pregnancy tests (MLPTs) at home to monitor hCG trends following assisted reproductive technology (ART). METHODS: One hundred and four women presenting for ART at either Stanford Medicine Fertility and Reproductive Health Clinic (Stanford, CA) or Hung Vuong Hospital (Ho Chi Minh City, Vietnam) participated in this pilot study. Women were asked to perform the MLPT at home, primarily on days when they were also scheduled to receive standard clinic-based serum hCG testing. These tests were administered up to 6 times over the 6-week period following embryo transfer or intrauterine insemination (IUI). Concordance of serial hCG readings for each time point was assessed by comparing trends in urine MLPT results with trends in serum hCG. Stable or increasing hCG level was interpreted as an indication of a progressing pregnancy, while a declining hCG was interpreted as a lack of established or progressing pregnancy. At study end, all participants were asked about the acceptability and convenience of using the MLPT at home for monitoring hCG trends following ART. RESULTS: Data from both urine and serum testing are available for 156 of 179 clinic visits (87.2%). There was high concordance of serial trend results between the two types of tests: among the 156 sets of serum and urine hCG data points, 150 (96.2%) showed a matching trend in hCG pattern and 6 (3.8%) resulted in a discordant trend. Seventy-three percent of women reported being satisfied or very satisfied with using the MLPTs at home. Almost all (96.6%) said that the MLPT was easy or very easy to use. CONCLUSION: The MLPT offers women and health care providers a client-friendly diagnostic tool to detect very early pregnancy and monitor its progress. TRIAL REGISTRATION: This study was registered on clinicaltrials.gov as NCT01846403 (May 1, 2013), and NCT01919502 (August 5, 2013).

Serial multilevel urine pregnancy testing to assess medical abortion outcome: a meta-analysis.

OBJECTIVES: To summarize data on the accuracy of a strategy designed to exclude ongoing pregnancy after medical abortion treatment by observing a decline in urine human chorionic gonadotropin (hCG) concentration as estimated by multilevel urine pregnancy tests (MLPTs) performed before and after treatment. STUDY DESIGN: We collated original data from seven studies performed by our organization that evaluated the accuracy of the MLPT strategy for assessment of outcome of medical abortion. Our first analysis included data from the five studies in which each participant was evaluated both with the MLPT strategy and with ultrasound or other clinical assessment. Our second analysis combined data from two randomized trials that compared the MLPT strategy to assessment by ultrasound. Both analyses included only participants treated at ≤63 days of gestation. RESULTS: In the first analysis, 1482 (93%) of 1599 participants had a decline in hCG concentration after treatment. Twenty-one (1.3%) had an ongoing pregnancy, none of whom had a decline (predictive value 100%, 95% CI 93.3%, 100%). The remaining 96 women (6.0%) had no decline without an ongoing pregnancy. The second analysis, which included 3762 participants with follow-up, found no significant difference in the rates of ongoing pregnancy ascertained in the randomized groups (RR 0.88; 95% CI 0.50, 1.54). Nearly all of the post-treatment MLPTs in the seven studies (3484/3535; 99%) were performed by the participants themselves. CONCLUSIONS: Serial multilevel urine pregnancy testing is a highly reliable and efficient strategy for excluding ongoing pregnancy after medical abortion at≤63 days of gestation. IMPLICATIONS STATEMENT: Serial urine testing using MLPTs can obviate the need for routine ultrasound or examination after medical abortion treatment and can allow most women to avoid an in-person follow-up visit to the abortion facility.

Self-administered multi-level pregnancy tests in simplified follow-up of medical abortion in Tunisia.

BACKGROUND: This study was conducted to assess the efficacy and acceptability of using a multi-level pregnancy test (MLPT) combined with telephone follow-up for medical abortion in Tunisia, where the majority of providers are midwives. METHODS: Four hundred and four women with gestational age ≤ 70 days' LMP seeking medical abortion at six study sites were enrolled in this open-label trial. Participants administered a baseline MLPT at the clinic prior to mifepristone administration and were asked to take a second MLPT at home and to call in its results before returning the day of their scheduled follow-up visit 10-14 days later. RESULTS: Almost all women with follow-up (97.1 %, n = 332/342) had successful abortions without the need for surgical intervention. The MLPT worked extremely well among women ≤63 days' LMP in ruling out ongoing pregnancy (negative predictive value (NPV) =100 % (n = 298/298)) and also detecting women with ongoing pregnancies (sensitivity = 100 %; 2/2) as needing follow-up due to non-declining hCG. Among women 64-70 days' LMP, the test also worked well in ruling out ongoing pregnancy (NPV = 96.9 % (n = 31/32) but not as well in terms of sensitivity (50 %), with only one of two ongoing pregnancies detected by MLPT as needing follow-up. Most women (95.1 %) found the MLPT to be very easy or easy to use and would consider using the MLPT again (97.4 %) if needed. CONCLUSIONS: Self-administered pre and post MLPT are very easy for women to use and accurate in assessing medical abortion success up to 63 days' LMP. MLPT use for medical abortion follow-up has the potential to facilitate task sharing services and eliminate the burden of routine in-person follow-up visits for the large majority of women. Additional research is warranted to explore the accuracy of the MLPT in identifying ongoing pregnancy among women with gestational ages > 63 days.
