- Brief Summary
Background: Medical abortions in Canada are provided using a standard regimen of methotrexate and misoprostol. After these medications are administered, patients are most commonly checked for termination of the pregnancy with an ultrasound and physical examination at an in-clinic follow-up appointment. These follow-up appointments can be inconvenient, costly, and take away from patient privacy. Furthermore, it has been suggested that these follow-up appointments may not be necessary for patients.
Objective: To determine whether remote follow-up, using telephone and blood testing is a feasible, safe, and effective method of follow-up after medical abortion, compared to standard care that requires an in-clinic visit and ultrasound.
This study offers women the option of remote follow-up by telephone combined with serum Beta-human chorionic gonadotropin (β-hCG) testing or standard in-clinic follow up. We will determine women's preferences for follow up, and compare adherence to the follow-up schedule, number of clinical contacts, and outcomes of the abortion. This study will be performed at two clinics in Toronto, the Bay Centre for Birth Control (BCBC) and the Choice in Health Clinic (CIHC).
Primary Hypothesis: Follow-up will be more successful with RFU, compared to SFU.
- Detailed Description
The protocol is altered for women who have an ultrasound that shows only a gestational sac (no yolk sac or fetal pole). Women in both follow-up groups will have β-hCG testing on the day of methotrexate injection and again in 8 days. If the level does not fall by 50% or they have concerning symptoms, they are asked to return to clinic for evaluation. If the β-hCG level falls by 50% or more, they will continue to be followed as per the protocol in their chosen group, but will be followed until their β-hCG becomes negative.

- Arm && Interventions
Group Intervention Description Standard Follow-up (SFU) Standard Follow-up (SFU) Women selecting SFU at either site (BCBC or CIHC) will schedule their in-person follow-up appointment before leaving the BCBC clinic on Study Day 1, when they receive their medication. In-person follow-up appointment will be scheduled for Study Day 15 (± 3 days)where, as per usual care, includes a history and a Post-abortion Checklist, transvaginal ultrasound, and a bimanual exam to confirm successful pregnancy expulsion. Remote Follow-up (RFU) Remote Follow-up (RFU) On Study Day 1 in both sites, women selecting RFU will receive 3 laboratory requisition forms for serum β-hCG testing and will be instructed to have testing done at a laboratory site of her choice on Study Day 10-12. The follow-up telephone appointment will be scheduled to take place on Study Day 15 (±3 days). For the follow-up telephone appointment, the research nurse/nurse practitioner will calculate the percentage fall in the β-hCG value. She will contact the subject by phone at the specified time, take a history of the timing of misoprostol use, resulting symptoms and complete the symptom Post-abortion Check-list. The research nurse/nurse practitioner, in consultation with the clinic physician if necessary, will confirm the information, determine whether other follow-up is required.
- Primary Outcome Measures
Name Time Method Rate of successful follow-up in women choosing RFU compared with those choosing SFU after medical abortion with M&M Within the designated time of 15 days post methotrexate injection ±3 days Successful follow-up will be defined as completion of telephone follow-up contact and serum β-hCG testing (for the RFU cohort) or attendance for the in-clinic follow-up visit within the designated time of 15 days post methotrexate injection ±3 days (for the SFU cohort).
- Secondary Outcome Measures
Name Time Method Percent of women in RFU and SFU groups who made no unscheduled visits related to medical abortion Within 28 days of methotrexate injection ±3 days Percent of women who choose RFU 1 day Percent of women choosing RFU who complete follow-up without a clinic visit Within the designated time of 15 days post methotrexate injection ±3 days
