Accuracy of emergency department triage using the Emergency Severity Index and independent predictors of under-triage and over-triage in Brazil: a retrospective cohort analysis.
This study sought to measure the frequency of under- and over-triage of patients by nurses using the Emergency Severity Index (ESI) in Brazil and to identify factors independently associated with each. It concluded that, despite rigorous and ongoing training of ESI users, a large number of patients in this cohort were under- or over-triaged. Advanced age, vital sign derangements, and specific chief complaints were particularly under-appreciated.

Characterizing New England emergency departments by telemedicine use.
The primary objective of this study was to describe the prevalence of telemedicine use in New England EDs and the clinical applications of use. It concluded that telemedicine is commonly used in New England EDs. In 2014, use was more common among rural EDs and EDs with limited neurology consultant availability. In contrast, telemedicine use was less common among very low-volume EDs.

Health care utilization rates after Oregon's 2008 Medicaid expansion: within-group and between-group differences over time among new, returning, and continuously insured enrollees.
The authors sought to assess changes in emergency department, primary care, mental and behavioral health care, and specialist care visit rates among individuals gaining Medicaid over 24 months postinsurance gain and also to evaluate the association of previous insurance with utilization. They found that primary care visit rates in both newly and returning insured individuals significantly exceeded those of the continuously insured in months 4 through 12, but were not significantly elevated in the second year. In contrast, emergency department utilization rates were significantly higher in returning insured compared with newly or continuously insured individuals and remained elevated over time. New visits to primary and specialist care were higher among those who gained Medicaid compared with the continuously insured throughout the study period. They concluded that expansion evaluations should allow for rate stabilization.

Assessment of innovative emergency department information displays in a clinical simulation center.
The authors assessed the functional utility of new display concepts for an emergency department information system created using cognitive systems engineering methods, by comparing them to similar displays currently in use. They found that participants using the new displays showed improved situation awareness, demonstrating that cognitive systems engineering methods can be used to create innovative displays that better support emergency medicine tasks, without increasing workload, compared to more standard displays.
