Use of an at-home multilevel pregnancy test and an automated call-in system to follow-up the outcome of medical abortion.

OBJECTIVE

To assess the feasibility of using an at-home multilevel pregnancy test (MLPT) and interactive voice response (IVR) call-in system for remote follow-up of medical abortion.

METHODS

A prospective pilot study was conducted among women who had a medical abortion at up to 70 days at a clinic in Mexico City, Mexico, between June 1, 2015, and January 30, 2016. Participants took an MLPT at the initial clinic visit and another MLPT at home 2 weeks later. They were requested to report their MLPT results via the IVR system and attend the clinic for follow-up evaluation.

RESULTS

Of 200 women considered for inclusion, 163 (81.5%) were included in the analysis. Only 10 (6.6%) of the 152 women who had a medical abortion on or before 63 days from last menstrual period reported MLPT results to the IVR system that required clinical evaluation to assess medical abortion outcome. The remaining 142 (93.4%) women in this group reported MLPT results that ruled out ongoing pregnancy (confirmed at clinical evaluation). Reported MLPT results ruled out ongoing pregnancy among the 11 women who had a medical abortion after 63 days; however, 1 (9%) had an ongoing pregnancy at clinical evaluation.

CONCLUSION

Use of MLPTs and the IVR system provided a streamlined approach to follow-up after medical abortion.
