Language Preference Impact On The Outcomes Of Those Lost To Follow-Up After A Diagnosis Of Pregnancy Of Unknown Location, Erin A. Leestma, Mayra A. Shafique, Megan Mcnitt, Annmarie Vilkins

Medical Student Research Symposium

Pregnancy of unknown location (PUL) is a temporary diagnosis when there is a positive pregnancy test but an intrauterine gestational sac and/or fetal pole are not visualized with ultrasonography. The three potential outcomes for such a pregnancy are failed pregnancy, an early intrauterine pregnancy or an ectopic/abnormal pregnancy. Given the serious associated morbidity of ectopic pregnancy, these PUL require strict follow up of bHCG levels to help the clinician determine the likely outcome of the PUL (failed vs early vs ectopic) and choose the best intervention (expectant management, surgical management or medical management). One potential barrier to follow-up identified in …
