Optimising the diagnosis of ectopic pregnancy

This retrospective cohort study reviewed the diagnosis of all ectopic pregnancies within a district general hospital over a 5-year period after the establishment of a dedicated Early Pregnancy Assessment Unit (EPAU). Of 215 ectopic pregnancies identified, notes were available for 208 (97%). Two-hundred and two cases were determined to have been diagnosed and managed as ectopic pregnancies. Six cases were excluded as they were pregnancies of unknown location managed as such. Overall, 91% were diagnosed by ultrasound scan, 5% were diagnosed clinically and 3% were diagnosed on serial human chorionic gonadotrophin (hCG) levels. This study found that the introduction of a dedicated, multi-professional, EPAU with a stable workforce improved ultrasound visualisation of ectopic pregnancies at first ultrasound scan from 22% prior to its commencement, to 61% over this period. The improvement in positive scan diagnosis of ectopic pregnancy was associated with a reduction in negative laparoscopy rate from 13% to 6%.
