Abstract

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.
