Promotion of Influenza Vaccination in the Emergency Department.

Background: Influenza vaccine uptake is low among underserved populations whose primary health care access occurs in emergency departments. We sought to determine whether implementation of two interventions would increase 30-day influenza vaccine uptake in unvaccinated patients in the emergency department.

Methods: This three-group, prospective, cluster-randomized controlled trial compared two interventions with a control group in noncritically ill, adult patients in the emergency department who were not vaccinated for influenza in the current vaccine season.

Elevated CK-MB with a normal troponin does not predict 30-day adverse cardiac events in emergency department chest pain observation unit patients.

Background: Prior studies indicate that an elevated creatinine kinase (CK)-MB imparts poor prognosis in patients with acute coronary syndrome despite a normal troponin. Its prognosis in the undifferentiated chest pain observation unit (CPU) population remains undefined.

Objective: To compare rates and predictors of 30-day adverse cardiac events in 2 cohorts (CK ±/MB+ vs.
