Variation in rates of hospital admission from the emergency department among Medicare patients at the regional, hospital, and physician levels.
Rates of admission from the emergency department (ED) vary widely across regions of the country, hospitals within regions, and physicians within hospitals. The study objective was to determine the extent to which variation in admission decisions was described by differences in admission rates at these 3 levels. The investigators concluded that within-area variation, both across hospitals within a region and across physicians within a hospital, was a more substantial component of observed variation in admission rates from the ED than regional level variation.

Analysis of consistency in emergency department physician variation in propensity for admission across patient sociodemographic groups.
The authors estimated the consistency of ED physician admission propensities across categories of patient sex, race and ethnicity, and Medicaid enrollment. They found that, although overall rates of admission differ systematically by patient sociodemographic factors, an individual physician's propensity to admit relative to other physicians appears to be applied consistently across sociodemographic groups of patients.

Effect of a split-flow physician in triage model on abdominal CT ordering rate and yield.
The objective of this study was to compare the rate and clinical yield of computed tomography (CT) imaging between patients presenting with abdominal pain initially seen by a physician in triage (PIT) versus those seen only by physicians working in the main emergency department (ED). For patients with abdominal pain, the investigators found no significant differences in rates of CT ordering or CT yield for patients seen in a PIT vs. traditional models.

Adverse events and emergency department opioid prescriptions in adolescents.
Understanding the risks associated with opioid prescription in adolescents is critical for informing opioid policy, but the risks are challenging to quantify given the lack of randomized trial data. Using a regression discontinuity design, the investigators exploited a discontinuous increase in opioid prescribing in the emergency department (ED) when adolescents transitioned from "child" to "adult" at age eighteen to estimate the effect of an ED opioid prescription on subsequent opioid-related adverse events.

Patient-reported opioid pill consumption after an ed visit: how many pills are people using?
This study examined opioid use patterns after an emergency department (ED) visit. The study was conducted at an urban academic emergency department and included patients 18 years or older, not chemically using opioids, and had been newly prescribed hydrocodone-acetaminophen. They were asked to complete and return a 10-day medication diary. Two-hundred sixty patients returned completed medication diaries that included treatment for different conditions. The mean age was 45 years and 59% of the sample was female. The median number of pills prescribed was 12. Patients with renal colic used the least number of pills and patients with back pain used the most. Almost all (92.5%) of patients had leftover pills by the end of the 10 days.

Nationwide emergency department imaging practices for pediatric urolithiasis: room for improvement.
The researchers describe the national use of computed tomography (CT) versus ultrasound imaging for pediatric patients seen at emergency departments (EDs) for suspected urolithiasis (SU) during the period 2006-2010. Use of CT was much higher than use of ultrasound, although it dropped off after 2007. Lowest CT use was seen at EDs that care for more children.
