ABSTRACT

OBJECTIVES: This study aimed to assess the feasibility, safety, and acceptability of asynchronous screening for medication abortion eligibility using a programmed questionnaire. STUDY DESIGN: For this study, we developed an informational website about medication abortion with a linked questionnaire programmed to produce a conclusion regarding eligibility according to standard criteria. We enrolled people in Colorado and Minnesota who submitted questionnaires indicating eligibility. A study physician reviewed each questionnaire and medical records if available and determined whether the responses warranted treatment without a synchronous clinical consultation or ultrasound. If so, the physician prescribed a standard regimen of mifepristone and misoprostol. We collected posttreatment data on abortion outcome, adverse events, and satisfaction. RESULTS: We received questionnaires from 197 individuals, of whom 160 remained in the study until the physician made a final treatment decision. Physicians prescribed medication abortion to 156 (97.5%) individuals based on the questionnaire responses, whereas four needed further assessment to confirm eligibility. Of the 156 individuals, 130 had sufficient follow-up to assess abortion outcome, and 123 (95%) had complete medication abortions without additional treatment. One participant was hospitalized for bleeding, and one expelled a 15-week fetus; however, it is not clear that conventional synchronous history-based screening would have averted these events. Of the 197 questionnaires, 42% were submitted outside business hours. On satisfaction questionnaires, 134 (96%) of 144 participants said they would recommend the study to a friend who needed an abortion. CONCLUSIONS: Data from this pilot project suggest that providing medication abortion based only on a self-administered, programmed questionnaire is likely to be effective, safe, efficient, and acceptable. IMPLICATIONS: A programmed self-administered patient questionnaire to assess eligibility for medication abortion could reduce the cost of the service, augment clinic efficiency, improve quality of care, and enhance access to abortion.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

OBJECTIVES: To assess whether planning high-sensitivity urine pregnancy tests (HSPT) rather than facility-based tests for medication abortion follow-up may increase risk of unplanned clinical visits or procedural completion of the abortion. STUDY DESIGN: We used data from the TelAbortion Project, a 5-year study assessing the safety and feasibility of providing mifepristone and misoprostol by telemedicine and mail in the United States. We categorized participants by whether the pretreatment follow-up plan included HSPT at home 3-5 weeks after treatment or facility-based tests (ultrasound or serum human chorionic gonadotropin) within 2 weeks after treatment. We used multivariable logistic regression to compare likelihood of post-treatment unplanned, abortion-related clinical visits and procedural intervention in these groups. RESULTS: Of 1324 patients who planned HSPT follow-up and 576 who planned facility-based tests, 85% and 83%, respectively, provided outcome information. Post-treatment clinical visits were less frequent in the HSPT group (19%) than in the facility-based test group (79%); most of the latter were to obtain the planned test. However, unplanned, abortion-related visits were significantly more common in the HSPT group (adjusted risk difference: 6.5%; p < 0.01). The likelihood of procedural completion did not differ by group. Planned follow-up test was not associated with delay in procedural completion or detection of ongoing pregnancy. CONCLUSIONS: Follow-up of medication abortion with home HSPT was associated with fewer post-treatment clinical visits, modestly more unplanned, abortion-related clinical visits, and no increase in the risk of procedural interventions or delayed identification or management of treatment failures. This option is an appropriate follow-up approach after medication abortion. IMPLICATIONS: Use of home high-sensitivity pregnancy tests rather than facility-based tests for outcome assessment after medication abortion is associated with a modest increase in unplanned clinical visits but does not lead to an increase in procedural interventions or delays identification and management of treatment failure.

ABSTRACT

Introduction: Prior studies indicate that PAPP-A could serve as a marker of gestational age (GA) with the potential to determine eligibility for medication abortion. The authors validated the relationship between PAPP-A and GA in an actual-use population. Materials & methods: The authors collected blood samples, medical histories and ultrasound-determined GA from patients presenting for abortion services. They measured PAPP-A using two immunoassays and assessed diagnostic accuracy for predicting GA ≥71 days. Results: The Ansh Labs and R&D Systems immunoassays produced an area under the ROC curve of 0.982 (95% CI: 0.958-0.994) and 0.986 (95% CI: 0.963-0.996), respectively, for predicting GA ≥71 days. Conclusion: This validation study in an intended-use population confirmed that PAPP-A has a strong ability to distinguish pregnancies above and below 71 days' gestation. Clinical trial registration: NCT04232189 (ClinicalTrials.gov).


In the USA, abortion with pills is an option for people with pregnancies of less than 71 days. Usually, people use ultrasound to find out how far along a pregnancy is. Ultrasound can be pricey and hard to find. Some studies show that a protein in blood, called PAPP-A, may be another option. The authors took blood from and did ultrasounds for people who wanted an abortion. They measured how much PAPP-A was in the blood using two different methods. The level of PAPP-A in the blood did a good job of distinguishing pregnancies that were higher and lower than 71 days.

ABSTRACT

OBJECTIVE: Given the substantial barriers to abortion access in the United States, many clinics now mail patients abortion medications. We examined whether dispensing the medications by mail prolonged time to medication use. STUDY DESIGN: We analyzed data from no-test medication abortions with medication provided either by mail or in a clinic from 11 United States clinics from February 2020 to January 2021. We examined mean number of days from patients' first contact with the clinic to mifepristone ingestion, its two-component intervals (first contact to medication dispensing and dispensing to mifepristone ingestion), and pregnancy duration at mifepristone ingestion. We used Poisson regression to compare mean outcomes across three dispensing methods: in-person, mailed from the clinic, and mailed from a mail-order pharmacy. RESULTS: Among the 2600 records, patients took mifepristone on average at 49 days of gestation (95% CI, 47-51) and 7 days (95% CI, 4-10) after first contact. Mean time from first contact to mifepristone ingestion was 6 days when medications were dispensed in-person and 9 days when mailed (p = 0.38). While time from first contact to dispensing was similar across methods (6 days in-person, 5 days mailed, p = 0.77), more time elapsed from dispensing to mifepristone ingestion when medications were mailed (4 days from clinic, 5 days from mail-order pharmacy) versus dispensed in-person (0.3 days, p < 0.001). Time to mifepristone ingestion was shorter with higher pregnancy duration. Pregnancy duration at ingestion was similar across methods (48 days in-person, 50 days mailed). CONCLUSIONS: Mailing medications did not significantly prolong time from patients' first contact with the clinic to mifepristone ingestion or increase pregnancy duration at mifepristone ingestion. IMPLICATIONS: Abortion providers should offer a range of medication abortion dispensing options, prioritizing patient preference.

ABSTRACT

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.

ABSTRACT

OBJECTIVE: To develop a drug facts label prototype for a combination mifepristone and misoprostol product and to conduct a label-comprehension study to assess understanding of key label concepts. METHODS: We followed U.S. Food and Drug Administration guidance, engaged a multidisciplinary group of experts, and conducted cognitive interviews to develop a drug facts label prototype for medication abortion. To assess label comprehension, we developed 11 primary and 13 secondary communication objectives related to indications for use, eligibility, dosing regimen, contraindications, warning signs, side effects, and recognizing the risk of treatment failure, with corresponding target performance thresholds (80-90% accuracy). We conducted individual structured video interviews with people with a uterus aged 12-49 years, recruited through social media. Participants reviewed the drug facts label and responded to questions to assess their understanding of each communication objective. After transcribing and coding interviews, we estimated the proportion of correct responses and exact binomial 95% CIs by age and literacy group. RESULTS: We interviewed 851 people (of 1,507 people scheduled); responses from 844 were eligible for analysis, and 35.7% (n=301) of participants were aged 12-17 years. The overall sample met performance criteria for 10 of the 11 primary communication objectives (93-99% correct) related to indications for use, eligibility for use, the dosing regimen, and contraindications; young people met nine and people with limited literacy met eight of the 11 performance criteria. Only 79% (95% CI 0.76-0.82) of the overall sample understood to contact a health care professional if little or no bleeding occurred soon after taking misoprostol, not meeting the prespecified threshold of 85.0%. CONCLUSION: Overall, high levels of comprehension suggest that people can understand most key drug facts label concepts for a medication abortion product without clinical supervision and recommend minor modifications.

ABSTRACT

Importance: Screening for medication abortion eligibility typically includes ultrasonography or pelvic examination. To reduce physical contact during the COVID-19 pandemic, many clinicians stopped requiring tests before medication abortion and instead screened patients for pregnancy duration and ectopic pregnancy risk by history alone. However, few US-based studies have been conducted on the outcomes and safety of this novel model of care. Objective: To evaluate the outcomes and safety of a history-based screening, no-test approach to medication abortion care. Design, Setting, and Participants: This retrospective cohort study included patients obtaining a medication abortion without preabortion ultrasonography or pelvic examination between February 1, 2020, and January 31, 2021, at 14 independent, Planned Parenthood, academic-affiliated, and online-only clinics throughout the US. Exposures: Medications for abortion provided without preabortion ultrasonography or pelvic examination and dispensed to patients in person or by mail. Main Outcomes and Measures: Effectiveness, defined as complete abortion after 200 µg of mifepristone and up to 1600 µg of misoprostol without additional intervention, and major abortion-related adverse events, defined as hospital admission, major surgery, or blood transfusion. Results: The study included data on 3779 patients with eligible abortions. The study participants were racially and ethnically diverse and included 870 (23.0%) Black patients, 533 (14.1%) Latinx/Hispanic patients, 1623 (42.9%) White patients, and 327 (8.7%) who identified as multiracial or with other racial or ethnic groups. For most (2626 [69.5%]), it was their first medication abortion. Patients lived in 34 states, and 2785 (73.7%) lived in urban areas. In 2511 (66.4%) abortions, the medications were dispensed in person; in the other 1268 (33.6%), they were mailed to the patient. Follow-up data were obtained for 2825 abortions (74.8%), and multiple imputation was used to account for missing data. Across the sample, 12 abortions (0.54%; 95% CI, 0.18%-0.90%) were followed by major abortion-related adverse events, and 4 patients (0.22%; 95% CI, 0.00%-0.45%) were treated for ectopic pregnancies. Follow-up identified 9 (0.40%; 95% CI, 0.00%-0.84%) patients who had pregnancy durations of greater than 70 days on the date the mifepristone was dispensed that were not identified at screening. The adjusted effectiveness rate was 94.8% (95% CI, 93.6%-95.9%). Effectiveness was similar when medications were dispensed in person (95.4%; 95% CI, 94.1%-96.7%) or mailed (93.3%; 95% CI, 90.7%-95.9%). Conclusions and Relevance: In this cohort study, screening for medication abortion eligibility by history alone was effective and safe with either in-person dispensing or mailing of medications, resulting in outcomes similar to published rates of models involving ultrasonography or pelvic examination. This approach may facilitate more equitable access to this essential service by increasing the types of clinicians and locations offering abortion care.

ABSTRACT

BACKGROUND: Medical abortion provided via telemedicine is becoming more widely available, potentially decreasing travel time for in-person abortion evaluation. METHODS: We conducted a retrospective chart review of all outpatient medical abortions from October 2016 through December 2019 at our academic medical centre in Portland, Oregon, USA. Using mifepristone administration logs, we identified patients who underwent abortion via direct-to-patient telemedicine or in clinic. Both groups had pre-abortion ultrasound examination. We extracted patient characteristics and geographic data to compare travel distance to clinic, ultrasound facility, and nearest advertised abortion clinic. We compared time from first contact until mifepristone ingestion and gestational age at mifepristone ingestion. RESULTS: Median distance from mailing address to clinic for 80 telemedicine and 124 clinic medical abortions was 95 (range 4-377) and 12 (range 0-184) miles (p<0.01). Distance travelled to ultrasound facility was shorter for telemedicine patients (median 7 miles, range 0-150 vs 12 miles, range 0-184; p<0.01) excluding outliers >200 miles. Distance to nearest advertised abortion clinic was equal between groups (median 7 miles, p=0.4). Time to mifepristone administration (ingestion) was longer (11 vs 6 days; p<0.01) and median gestational age was higher (49 vs 44 days; p=0.01) for telemedicine. CONCLUSIONS: Telemedicine increases the reach of abortion providers and provides care to more geographically distant patients. Patients chose telemedicine abortion even when they had an equidistant option, suggesting that patients value telemedicine for reasons other than geographic convenience. This telemedicine delivery model that included ultrasound testing prior to abortion resulted in up to a 5-day delay in abortion initiation, which was not clinically significant.

ABSTRACT

BACKGROUND: Mifepristone, used together with misoprostol, is approved by the United States Food and Drug Administration for medication abortion through 10 weeks' gestation. Although in-person ultrasound is frequently used to establish medication abortion eligibility, previous research demonstrates that people seeking abortion early in pregnancy can accurately self-assess gestational duration using the date of their last menstrual period. OBJECTIVE: In this study, we establish the screening performance of a broader set of questions for self-assessment of gestational duration among a sample of people seeking abortion at a wide range of gestations. STUDY DESIGN: We surveyed patients seeking abortion at 7 facilities before ultrasound and compared self-assessments of gestational duration using 11 pregnancy dating questions with measurements on ultrasound. For individual pregnancy dating questions and combined questions, we established screening performance focusing on metrics of diagnostic accuracy, defined as the area under the receiver operating characteristic curve, sensitivity (or the proportion of ineligible participants who correctly screened as ineligible for medication abortion), and proportion of false negatives (ie, the proportion of all participants who erroneously screened as eligible for medication abortion). We tested for differences in sensitivity across individual and combined questions using McNemar's test, and for differences in accuracy using the area under the receiver operating curve and Sidak adjusted P values. RESULTS: One-quarter (25%) of 1089 participants had a gestational duration of >70 days on ultrasound. Using the date of last menstrual period alone demonstrated 83.5% sensitivity (95% confidence interval, 78.4-87.9) in identifying participants with gestational durations of >70 days on ultrasound, with an area under the receiver operating characteristic curve of 0.82 (95% confidence interval, 0.79-0.85) and a proportion of false negatives of 4.0%. A composite measure of responses to questions on number of weeks pregnant, date of last menstrual period, and date they got pregnant demonstrated 89.1% sensitivity (95% confidence interval, 84.7-92.6) and an area under the receiver operating curve of 0.86 (95% confidence interval, 0.83-0.88), with 2.7% of false negatives. A simpler question set focused on being >10 weeks or >2 months pregnant or having missed 2 or more periods had comparable sensitivity (90.7%; 95% confidence interval, 86.6-93.9) and proportion of false negatives (2.3%), but with a slightly lower area under the receiver operating curve (0.82; 95% confidence interval, 0.79-0.84). CONCLUSION: In a sample representative of people seeking abortion nationally, broadening the screening questions for assessing gestational duration beyond the date of the last menstrual period resulted in improved accuracy and sensitivity of self-assessment at the 70-day threshold for medication abortion. Ultrasound assessment for medication abortion may not be necessary, especially when requiring ultrasound could increase COVID-19 risk or healthcare costs, restrict access, or limit patient choice.

ABSTRACT

BACKGROUND: Accurate pregnancy dating is critical for maternal and child health and for counseling on safe and effective abortion methods. While last menstrual period and first trimester ultrasound are often used together to determine gestational age (GA), they have limited accuracy and availability, respectively. Prior studies have shown that pregnancy-associated plasma protein-A (PAPP-A) increases exponentially during pregnancy and has the potential to serve as a biochemical marker of GA. We aimed to analyze the relationship between sonographically determined GA and serum PAPP-A concentration measured by different immunoassays and to derive cutoff levels informative for the 70 days GA commonly recommended limit for medical abortion in outpatient settings. METHODS: We compared technical characteristics of 4 commercially available PAPP-A immunoassays and tested 120 maternal serum samples (GA range: 34-231 days) along with contrived pool samples and traceable quality controls. These characteristics included area under the receiver operator characteristic (AUROC) plot, sensitivity and specificity based on cutoffs defined by the Youden Index, and likelihood ratios. RESULTS: All 4 immunoassays had sensitivities and specificities ≥80%, and AUROC values ranging from 0.948 to 0.968. Marked differences among absolute PAPP-A values were noted depending on immunoassay. PAPP-A cutoff values at 70 days GA for each individual immunoassay were established along with procedural recommendations that increase equivalence among immunoassays. CONCLUSIONS: Maternal serum PAPP-A levels correlated strongly with GA despite differences in immunoassay formats and absolute data output. Serum PAPP-A has biomarker potential for future development of a point-of-care test aimed at increasing access to medical abortion.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.
