BACKGROUND: The study was conducted to assess the effectiveness of early medical abortion (EMA) in women with early pregnancy and no defined intrauterine gestational sac (IUGS) on ultrasound. STUDY DESIGN: Retrospective, multicenter, observational study of oral mifepristone 200 mg and buccal misoprostol 800 mcg administered 24-48 h later for EMA (gestations ≤63 days). Odds ratios (ORs) [95% confidence intervals (CIs)] of EMA failure and continuing pregnancy for women with no defined IUGS vs. those with confirmed IUGS were calculated. RESULTS: Women with no defined IUGS were more likely to experience EMA failure [9.0% (6/67) vs. 3.5% (465/13,345); OR (95% CI)=2.72 (1.17-6.33), p=.041] and continuing pregnancy [7.5% (5/67) vs. 0.6% (83/13,345); OR (95% CI)=12.72 (4.98-32.46), p<.001]. CONCLUSION: EMA failure is more likely in women with early pregnancy and no defined IUGS than those with gestations ≤63 days and confirmed IUGS. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry identifier: ACTRN12611001051932.
