Siegfried I, et al. - Researchers undertook a prospective study between 8/2016–8/2017 on patients >18 years referred directly to their ED from surrounding urgent care centers (UCCs), to describe adult ED referrals from UCCs. Further, they determined the percentage of referrals considered critical, complex, and simple. Three hundred seventeen patient encounters were analyzed; 23 (7.3%) considered critical, 254 (80.1%) complex, and 40 (12.6%) simple. Among all ED referrals, abdominal pain (62 encounters), chest pain (28), shortness of breath (16), eye pain/injury (16), and leg pain/swelling (15) were the most common chief complaints. Laboratory diagnostic investigations were done in 68% of patients and radiologic investigations in 69%. Consultation from a subspecialist was required in 37% of patients. They recommend individual UCCs to evaluate their current states of ED referrals and develop educational and preparedness strategies based on the epidemiology of adult emergencies that may occur.
