The objective was to assess the performance of a clinical practice guideline for evaluation of possible appendicitis in children. The guideline incorporated risk stratification, staged imaging, and early surgical involvement in high-risk cases. ⋯ The clinical practice guideline performed well in a general teaching hospital. Rates of negative appendectomy and missed appendicitis were low and 58% of patients were managed without a CT scan.

Comparative Study
A cost-effectiveness analysis of dexamethasone versus prednisone in pediatric acute asthma exacerbations.
The objective was to evaluate the cost-effectiveness of dexamethasone versus prednisone for the treatment of pediatric asthma exacerbations in the emergency department (ED). ⋯ This decision analysis model illustrates that use of 2 days of dexamethasone instead of 5 days of prednisone at the time of ED visit for asthma leads to a decreased number of ED visits and hospital admissions within 7 to 10 days of the sentinel ED visit and provides cost savings.

Previous studies have confirmed the prognostic significance of lactate concentrations categorized into groups (low, intermediate, high) among emergency department (ED) patients with suspected infection. Although the relationship between lactate concentrations categorized into groups and mortality appears to be linear, the relationship between lactate as a continuous measurement and mortality is uncertain. This study sought to evaluate the association between blood lactate concentrations along an incremental continuum up to a maximum value of 20 mmol/L and mortality. ⋯ In ED patients with suspected infection, we found a curvilinear relationship between incremental elevations in lactate concentration and mortality. These data support the use of lactate as a continuous variable rather than a categorical variable for prognostic purposes.

The objective was to assess the relationship between alcohol use and misuse and patient sex among emergency department (ED) patients by comparing self-reported estimates of quantity and frequency of alcohol use, estimated blood alcohol concentrations (eBACs) when typically drinking and during heavy episodic drinking (binging), and alcohol misuse severity, to understand sex differences in alcohol use and misuse for this population. ⋯ Although men drink more than women, women have similar eBACs with comparable levels of alcohol misuse. Women may benefit from recognizing that they are reaching similar levels of intoxication compared to men. Addressing these differences and possible health implications in future ED brief interventions may induce changes in problematic alcohol use among women.

Previous studies have noted a sharp increase in utilization of physician assistants (PAs) and nurse practitioners (NPs), up to 13% of all U.S. emergency department (ED) visits in 2005. The authors sought to reevaluate utilization and visit acuity for these midlevel providers (MLPs) in U.S. EDs from 2006 to 2009. ⋯ Despite a rapid expansion of MLP utilization in U.S. EDs, recent growth appears to have plateaued. The scope of practice of MLPs in EDs does not appear to be rapidly expanding. Urban EDs use MLPs more than nonurban EDs, but among EDs that use MLPs, nonurban EDs had MLPs see a larger proportion of overall ED visits.
