RESUMEN

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.

RESUMEN

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).

RESUMEN

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. TRIAL REGISTRATION: This study was registered on May 13, 2010, on clinicaltrials.gov as NCT01150279 .

RESUMEN

Extensive evidence exists regarding the efficacy and acceptability of medical abortion through 63 days since last menstrual period (LMP). In Mexico City's Secretariat of Health (SSDF) outpatient facilities, mifepristone-misoprostol medical abortion is the first-line approach for abortion care in this pregnancy range. Recent research demonstrates continued high rates of complete abortion through 70 days LMP. To expand access to legal abortion services in Mexico City (where abortion is legal through 12 weeks LMP), this study sought to assess the efficacy and acceptability of the standard outpatient approach through 70 days in two SSDF points of service. One thousand and one women seeking pregnancy termination were enrolled and given 200 mg mifepristone followed by 800 µg misoprostol 24-48 hours later. Women were asked to return to the clinic one week later for evaluation. The great majority of women (93.3%; 95% CI: 91.6-94.8) had complete abortions. Women with pregnancies ≤ 8 weeks LMP had significantly higher success rates than women in the 9th or 10th weeks (94.9% vs. 90.5%; p = 0.01). The difference in success rates between the 9th and 10th weeks was not significant (90.0% vs. 91.2%; p = 0.71). The majority of women found the side effects (82.9%) and the use of misoprostol (84.4%) to be very acceptable or acceptable. This study provides additional evidence supporting an extended outpatient medical abortion regimen through 10 weeks LMP.

RESUMEN

Young women and girls in South Africa are at high risk of unintended pregnancy and HIV. Previous studies have reported barriers to contraceptive and other sexual and reproductive health (SRH) services among young women in this context. We aimed to assess young women's SRH knowledge and experiences and to determine how they get SRH information and services in Soweto, South Africa using quantitative and qualitative methods. Young women, aged 18-24, recruited from primary health clinics and a shopping mall, reported that they have access to SRH information and know where to obtain services. However there are challenges to accessing and utilizing information and services including providers' unsupportive attitudes, uneven power dynamics in relationships and communication issues with parents and community members. There is a need to assist young women in understanding the significance of SRH information. They need access to age-appropriate, youth-friendly services in order to have healthy sexual experiences.

RESUMEN

BACKGROUND: Trials of interventions for PPH prevention and treatment rely on different measurement methods for the quantification of blood loss and identification of PPH. This study's objective was to compare measures of blood loss obtained from two different measurement protocols frequently used in studies. METHODS: Nine hundred women presenting for vaginal delivery were randomized to a direct method (a calibrated delivery drape) or an indirect method (a shallow bedpan placed below the buttocks and weighing the collected blood and blood-soaked gauze/pads). Blood loss was measured from immediately after delivery for at least one hour or until active bleeding stopped. RESULTS: Significantly greater mean blood loss was recorded by the direct than by the indirect measurement technique (253.9 mL and 195.3 mL, respectively; difference = 58.6 mL (95% CI: 31-86); p < 0.001). Almost twice as many women in the direct than in the indirect group measured blood loss > 500 mL (8.7% vs. 4.7%, p = 0.02). CONCLUSIONS: The study suggests a real and significant difference in blood loss measurement between these methods. Research using blood loss measurement as an endpoint needs to be interpreted taking measurement technique into consideration. TRIAL REGISTRATION: This study has been registered at clinicaltrials.gov as NCT01885845.

RESUMEN

BACKGROUND: Complications following spontaneous or induced abortion are a major cause of maternal morbidity. To manage these complications, post-abortion care (PAC) services should be readily available and easy to access. Standard PAC treatment includes surgical interventions that are highly effective but require surgical providers and medical centers that have the necessary space and equipment. Misoprostol has been shown to be an effective alternative to surgical evacuation and can be offered by lower level clinicians. This study sought to assess whether 400 mcg sublingual misoprostol could effectively evacuate the uterus after incomplete abortion and to confirm its applicability for use at lower level settings. METHODS: All women presenting with incomplete abortion at one of three hospitals in Vietnam were enrolled. Providers were not asked to record if the abortion was spontaneous or induced. It is likely that all were spontaneous given the legal status and easy access to abortion services in Vietnam. Participants were given 400 mcg sublingual misoprostol and instructed to hold the pills under their tongue for 30 minutes and then swallow any remaining fragments. They were then asked to return one week later to confirm their clinical status. Study clinicians were instructed to confirm a complete expulsion clinically. All women were asked to complete a questionnaire regarding satisfaction with the treatment. RESULTS: Three hundred and two women were enrolled between September 2009 and May 2010. Almost all participants (96.3%) had successful completions using a single dose of 400 mcg misoprostol. The majority of women (87.2%) found the side effects to be tolerable or easily tolerable. Most women (84.3%) were satisfied or very satisfied with the treatment they received; only one was dissatisfied (0.3%). Nine out of ten women would select this method again and recommend it to a friend (91.0% and 90.0%, respectively). CONCLUSIONS: This study confirms that 400 mcg sublingual misoprostol effectively evacuates the uterus for most women experiencing incomplete abortion. The high levels of satisfaction and side effect tolerability also attest to the ease of use of this method. From these data and given the international consensus around the effectiveness of misoprostol for incomplete abortion care, it seems timely that use of the drug for this indication be widely expanded both throughout Vietnam and wherever access to abortion care is limited. TRIAL REGISTRATION: ClinicalTrials.gov, NCT00670761.

RESUMEN

BACKGROUND: Abortion services are legally available in Ukraine although there are issues in quality and access. Two studies were conducted in Ukraine to expand options for women, and to determine the efficacy and acceptability of medical abortion. STUDY DESIGN: Two open-label clinical trials were conducted at six clinics in Ukraine. Women were given 200 mg mifepristone followed after 48 hours by 400 µg oral misoprostol (Study One) and mifepristone followed after 24 hours by 400 µg sublingual misoprostol (Study Two). Follow-up visits were scheduled for two weeks after mifepristone administration to assess whether complete uterine evacuation had occurred. RESULTS: Success rates were 97% in the first study and 98% in the second one. The vast majority of participants were satisfied or very satisfied with their abortion method (Study One: 94%; Study Two: 98%). CONCLUSIONS: The two studies demonstrate high rates of success and acceptability of early medical abortion in Ukraine.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: In low-resource settings, where abortion is highly restricted and self-induced abortions are common, access to post-abortion care (PAC) services, especially treatment of incomplete terminations, is a priority. Standard post-abortion care has involved surgical intervention but can be hard to access in these areas. Misoprostol provides an alternative to surgical intervention that could increase access to abortion care. We sought to gather additional evidence regarding the efficacy of 400 mcg of sublingual misoprostol vs. standard surgical care for treatment of incomplete abortion in the environments where need for economical non-surgical treatments may be most useful. METHODS: A total of 860 women received either sublingual misoprostol or standard surgical care for treatment of incomplete abortion in a multi-site randomized trial. Women with confirmed incomplete abortion, defined as past or present history of vaginal bleeding during pregnancy and an open cervical os, were eligible to participate. Participants returned for follow-up one week later to confirm clinical status. If abortion was incomplete at that time, women were offered an additional follow-up visit or immediate surgical evacuation. RESULTS: Both misoprostol and surgical evacuation are highly effective treatments for incomplete abortion (misoprostol: 94.4%, surgical: 100.0%). Misoprostol treatment resulted in a somewhat lower chance of success than standard surgical practice (RR = 0.90; 95% CI: 0.89-0.92). Both tolerability of side effects and women's satisfaction were similar in the two study arms. CONCLUSION: Misoprostol, much easier to provide than surgery in low-resource environments, can be used safely, successfully, and satisfactorily for treatment of incomplete abortion. Focus should shift to program implementation, including task-shifting the provision of post-abortion care to mid- and low- level providers, training and assurance of drug availability. TRIAL REGISTRATION: This study has been registered at clinicaltrials.gov as NCT00466999 and NCT01539408.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

In this cross-sectional, clinic-based study, we estimated 1-year prevalence of intimate partner violence among 986 patients who had elective abortions. We assessed physical, sexual, and battering intimate partner violence via self-administered, computer-based questionnaires. Overall, physical and sexual intimate partner violence prevalence was 9.9% and 2.5%, respectively; 8.4% of those in a current relationship reported battering. Former partners perpetrated more physical and sexual assaults than did current partners. Violence severity increased with frequency. Abortion patients experience high intimate partner violence rates, indicating the need for targeted screening and community-based referral.
