Learners, either medical students or residents, often perform the initial assessment of patients visiting the emergency department (ED). It is unclear, however, if learners affect the rate of short-term unscheduled return visits. The objective of this study was to determine if the involvement of learners in ED visits increases the rate of return visits. ⋯ This study demonstrated that the involvement of learners in ED patient assessments is not associated with increased odds of short-term unscheduled return visits.

Pain and bleeding complicate 30% of pregnancies, raising concerns for viability. The objective is to evaluate the diagnostic characteristics of a single serum progesterone level in assessing pregnancy viability among symptomatic patients. ⋯ A single progesterone level provides a clinically useful prognostic information on pregnancy viability. More than nine out of ten patients with a level < 6.3 ng/mL (< 20.034 nmol/L) will be diagnosed with a non-viable pregnancy, and more than 90% of patients with a level ≥ 20-25 ng/mL (63.6-79.5 nmol/L) will have a viable pregnancy confirmed.
