Introduction: The objective of this study was to determine the proportion of women who had a ruptured ectopic pregnancy after being discharged from the ED where ectopic pregnancy had not yet been excluded. Methods: This was a retrospective chart review of pregnant (<12 week gestational age) women discharged home from an academic tertiary care ED with a diagnosis of ectopic pregnancy, rule out ectopic pregnancy, or pregnancy of unknown location (PUL) over a 7 year period. Results: Of the 550 included patients, 83 (15.1%) had a viable pregnancy, 94 (17.1%) had a spontaneous or missed abortion, 230 (41.8%) had an ectopic pregnancy, 72 (13.1%) had unknown outcomes and 71 (12.9%) had other outcomes which included therapeutic abortion, molar pregnancy or resolution of HCG with no location documented. Of the 230 ectopic pregnancies, 42 (7.6%) underwent expectant management, 131 (23.8%) were managed medically with methotrexate, 29 (5.3%) were managed with surgical intervention, and 28 (5.1%) patients had a ruptured ectopic pregnancy after their index ED visit. Of the 550 included patients, 221 (40.2%) did not have a transvaginal US during their index ED visit, 73 (33.0%) were subsequently diagnosed with an ectopic pregnancy. Conclusion: These results may be useful for ED physicians counselling women with symptomatic early pregnancies about the risk of ectopic pregnancy after they are discharged from the ED.
