Comparing office and telephone follow-up after medical abortion

ObjectivesCompare proportion lost to follow-up, successful abortion, and staff effort in women who choose office or telephone-based follow-up evaluation for medical abortion at a teaching institution.Study designWe performed a chart review of all medical abortions provided in the first three years of service provision. Women receiving mifepristone and misoprostol could choose office follow-up with an ultrasound evaluation one to two weeks after mifepristone or telephone follow-up with a scheduled telephone interview at one week post abortion and a second telephone call at four weeks to review the results of a home urine pregnancy test.ResultsOf the 176 medical abortion patients, 105 (59.7%) chose office follow-up and 71 (40.3%) chose telephone follow-up. Office evaluation patients had higher rates of completing all required follow-up compared to telephone follow-up patients (94.3% vs 84.5%, respectively, p = .04), but proportion lost to follow-up was similar in both groups (4.8% vs 5.6%, respectively, p = 1.0). Medical abortion efficacy was 94.0% and 92.5% in women who chose office and telephone follow-up, respectively. We detected two (1.2%) ongoing pregnancies, both in the office group. Staff rescheduled 15.0% of appointments in the office group. For the telephone follow-up cohort, staff made more than one phone call to 43.9% and 69.4% of women at one week and four weeks, respectively.ConclusionsProportion lost to follow-up is low in women who have the option of office or telephone follow-up after medical abortion. Women who choose telephone-based evaluation compared to office follow-up may require more staff effort for rescheduling of contact, but overall outcomes are similar.ImplicationsAlthough women who choose telephone evaluation may require more rescheduling of contact as compared to office follow-up, having alternative follow-up options may decrease the proportion of women who are lost to follow-up.
