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

Evaluation of telemedicine medical abortion using a no-test protocol in the Eastern Europe and Central Asian region: Evidence from Ukraine, Uzbekistan, and Azerbaijan

OBJECTIVE

To evaluate safety, feasibility, and acceptability of a telemedicine medical abortion service without pre-treatment in-person tests in Ukraine, Uzbekistan, and Azerbaijan.

METHODS

We conducted an open-label, prospective, observational clinical study at five clinics in the three countries. Interested and eligible participants scheduled a telemedicine consultation with a study provider by phone or video. Medical abortion pills could be obtained by mail or courier or picked up at the study clinic or a pharmacy. Study providers contacted participants 1 week after mifepristone ingestion to assess abortion outcomes based on symptoms, and 3 weeks later to review the result of an at-home, high-sensitivity, urine pregnancy test. Participants were referred to in-person visit based on symptoms, urine pregnancy test results, or initiative by the participant.

RESULTS

In all, 300 women participated in the study. Almost all participants received medical abortion medications the same day as their first contact with the study clinic, and the majority (n = 297, 99.0%) did not experience any problems receiving them. All except two women (0.67%) followed provider instructions on administration of medications. The majority of participants had a complete abortion without a procedure (Ukraine: n = 115, 95.8%; Uzbekistan: n = 127, 97.7%; Azerbaijan: n = 49, 98.0%), few had in-person visits (Ukraine: n = 30, 25.0%; Uzbekistan: n = 3, 2.3%; Azerbaijan: n = 4, 8.0%), and most were very satisfied or satisfied with the service (Ukraine: n = 116, 96%; Uzbekistan: n = 128, 98%; Azerbaijan: n = 45, 90%). No serious adverse events occurred.

CONCLUSION

Telemedicine medical abortion using the no-test protocol is safe, feasible and acceptable for women in Ukraine, Uzbekistan, and Azerbaijan.

Telephone follow-up after early medical abortion using Australia's first low sensitivity urine pregnancy test

BACKGROUND

Follow-up after early medical abortion (EMA) in Australia often entails tracking serum human chorionic gonadotropin levels or performing ultrasonography in-clinic. In other countries, methods of follow-up such as using a low-sensitivity urine pregnancy test (LSUPT), telephone evaluation and a questionnaire have been demonstrated to be safe and acceptable.

AIMS

To evaluate the safety and efficacy of telephone follow-up after EMA using an LSUPT and questionnaire.

MATERIALS AND METHODS

A prospective observational cohort study of patients undergoing telephone follow-up after EMA using an LSUPT and questionnaire was conducted from March 26 to July 31, 2020. Outcomes of patients who returned to clinic because of a positive LSUPT were evaluated and adverse event rates were calculated. Routinely collected adverse event information was used to compare complication rates during the evaluation period with that prior to introduction of the LSUPT.

RESULTS

During the study period, 2223 patients underwent the new protocol. One hundred and ninety-seven patients had a positive LSUPT at their telephone follow-up. One hundred and thirty-two had an incomplete abortion, 11 had a continuing pregnancy, 53 had a complete abortion and one left the clinic before full assessment.

CONCLUSIONS

Introduction of telephone follow-up with an at-home LSUPT reduced the number of patients requiring unnecessary clinic appointments, with over 90% of patients completing their follow-up at home. Complication rates during the study period were found to be at least comparable with previously identified organisational adverse events.

Medication Abortion: A Comprehensive Review

This chapter provides an overview of evidence-based guidelines for medication abortion in the first trimester. We discuss regimens, both FDA-approved and other clinical-based protocols, and will briefly discuss novel self-managed abortion techniques taking place outside the formal health care system. Overview of patient counseling and pain management are presented with care to include guidance on "no touch" regimens that have proven both feasible and effective. We hope that this comprehensive review helps the health care community make strides to increase access to abortion in a time when reproductive health care is continuously restricted.

Self-managed Medication Abortion in the United States

Self-managed abortion (SMA) is ending a pregnancy without medical supervision, either by obtaining medications (known as self-managed medication abortion) or through other means. Many factors influence a person's decision to pursue self-managed abortion, such as time constraints, financial considerations, and local availability of abortion services. We present on the prevalence, methods and best practices for clinicians in the United States who may interface with individuals undergoing self-managed medication abortion at any point in the process through a harm reduction approach.

Implications of using home urine pregnancy tests versus facility-based tests for assessment of outcome following medication abortion provided via telemedicine

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.

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.

Update on medication abortion follow-up options: many sizes to fit all

PURPOSE OF REVIEW

To assess the efficacy, benefits, and limitations of available and emerging follow-up options for medication abortion.

RECENT FINDINGS

Medication abortion follow-up does not have to be a 'one size fits all' protocol. From most to least invasive, follow-up options include facility-based ultrasound, laboratory-based repeat serum beta-human chorionic gonadotropin (hCG) testing, urine hCG testing (high sensitivity, low sensitivity, and multilevel pregnancy tests), self-assessment with symptom evaluation, and no intervention. Provider or facility-dependent follow-up, including ultrasound and serum testing are effective, but have several limitations, including needing to return to a facility and cost. Remote, client-led follow-up options, such as urine pregnancy testing and symptoms evaluation, are well tolerated and effective for ruling out the rare outcome of ongoing pregnancy after medication abortion and have several advantages. Advantages include being inexpensive and flexible. However, it is important to note that low-sensitivity and multilevel pregnancy tests are not available in all settings. In studies evaluating client-led follow-up with urine pregnancy tests, ongoing pregnancies were identified over half the time with symptoms alone.

SUMMARY

Guidelines from several professional organizations have aligned with the evidence and no longer recommend routine office-based follow-up. To ensure care is person-centered, providers should offer follow-up options that align with the comfort, logistical ability, and values of the client.

Telemedicine for First-Trimester Medical Abortion in Canada: Results of a 2019 Survey

Introduction: Telemedicine has the potential to improve abortion access disparities in Canada. We aimed to explore the provision of telemedicine for first-trimester medical abortion and related barriers in 2019. Methods: We conducted a national, cross-sectional, anonymized, web-based survey of clinicians who provided abortion care in 2019 in Canada. We distributed our survey through professional health organizations to maximize identification of possible eligible respondents and used a modified Dillman technique to foster responses. Questions elicited provider demographics, clinical characteristics, including telemedicine first-trimester medical abortion and perceived related barriers. Descriptive statistics were analyzed using R software. Results: Among 465 respondents, 388 reported providing first-trimester medical abortion across Canada; 44.0% reported experience using telemedicine for some components of care: 49.3% of primary care clinicians and 28.7% of specialists. Telemedicine was used for initial consultation (86.0%), prescription (82.2%), or follow-up (92.2%). The median percentage of telemedicine providers' patients who underwent a dating ultrasound was 90.0. The majority usually followed up with patients through quantitative human chorionic gonadotropin (hCG) (84.2%). Seventy-eight percent perceived barriers to telemedicine; the most common being inability to confirm gestational age with ultrasound (43.0%), and lack of provincial telemedicine abortion fee code to pay practitioners (30.2%), timely access to serum hCG testing (24.6%), and nearby emergency services (23.3%). Discussion: In 2019, fewer than half of respondents reported providing some aspects of first-trimester medical abortion through telemedicine and the majority perceived barriers. Our results can inform knowledge translation activities to reduce barriers and increase telemedicine abortion care in Canada.
