Bleeding in the first trimester of pregnancy is a common presentation to the Emergency Department (ED) with half going on to miscarry. Currently there is no local consensus on key quality markers of care for such cases. Point of Care Ultrasound (PoCUS) is increasingly utilized in the ED to detect life threating pathology such as an ectopic pregnancy or fetal viability. PoCUS leads to improved patient satisfaction, quicker diagnosis and treatment. The purpose for this study was to examine the

Methods: A retrospective cohort study of pregnant females presenting to the ED with first trimester bleeding over one year (June 2016 – June2017) was completed. A sample size of 108 patients was required to detect a moderate departure from baseline reported rates (67.8 – 77.6%). The primary outcome was the PoCUS rate in the ED. The main secondary outcome was the formal ultrasound rate. The literature recommends PoCUS in all early pregnancy bleeding in the ED, with a target of 100% of patients receiving PoCUS. Additional data recorded included the live birth rate, pelvic and speculum examination rate and lab tests. There is no clearly defined ideal practice for the additional data so these rates will be recorded without comparison. Results: Records of 168 patients were screened for inclusion. 65 cases were excluded because they were not pregnant or had confirmed miscarriage or other, leaving a total of 103 patients included in the analysis. The PoCUS rate was 51.5% (95% CI 42%-61%), lower than previously reported PoCUS rates of 73% (67.8 – 77.6%). The formal ultrasound rate was 67% (57%-75%). Both approaches were significantly lower than the recommended rate of 100% (95.7 – 100%). Rates for other key markers of care will also be presented. Conclusion: Fewer PoCUS exams were performed at our centre compared with reported and recommended rates for ultrasound. Further results will explore our current practice in the management of first trimester pregnancy complications. We plan to use this information to suggest improvements in the management of this patient population.
