Multicenter Study Comparative Study
Increased rate of central venous catheterization procedures in community EDs.
Central venous catheterization (CVC) is integral to the emergency department (ED) treatment of critically ill patients, such as those receiving early goal-directed therapy for severe sepsis. No previous studies have described the overall use of CVC in community EDs. The objective of this study was to estimate the overall frequency and temporal trends in CVC use in a sample of patients visiting community EDs. ⋯ The overall rate of CVC increased from 2004 to 2008. However, there was a wide variation among Eds, and the CVC rate was lower in rural compared with urban EDs. The increase in CVC use in urban EDs may reflect more intensive therapy in the management of ED patients with acute illness or injury. Future efforts are needed to optimize best practices for the use of CVC in community ED practices and to characterize factors responsible for urban rural differences in the rate of CVC procedures.

There are no clear recommendations for the diagnostic evaluation of patients who present to the emergency department (ED) with asymptomatic elevated blood pressure. In patients presenting with asymptomatic elevated blood pressure in the ED, we measured the prevalence of abnormalities on a basic metabolic profile (BMP) that led to hospital admission as well as the prevalence of diminished renal function. ⋯ In a homogenous African American population presenting to the ED with asymptomatic elevated BP, there is a relatively high prevalence of abnormalities on the BMP that led to hospital admission. We suggest routine testing of a serum creatinine should be strongly considered in a largely African American patient population with asymptomatic elevated BP in the ED.

Randomized Controlled Trial Multicenter Study
ED antibiotic use for acute respiratory illnesses since pneumonia performance measure inception.
The study aimed to determine if emergency department (ED)-administered antibiotics for patients discharged home with nonpneumonia acute respiratory tract infections (ARIs) have increased since national pneumonia performance measure implementation, including antibiotic administration within 4 hours of arrival. ⋯ Emergency department-administered antibiotics did not increase for patients with acute cough discharged home with nonpneumonia ARIs since pneumonia antibiotic timing performance measure implementation in these academic EDs.

Multicenter Study
ED visit volume and quality of care in acute exacerbations of chronic obstructive pulmonary disease.
The purpose of this study is to determine whether emergency department (ED) visit volume is associated with ED quality of care in patients with acute exacerbations of chronic obstructive pulmonary disease (COPD). ⋯ Traditional positive volume-quality relationships did not apply to emergency care of COPD exacerbation. High-volume EDs used less guideline-recommended diagnostic procedures, had a higher admission threshold, and had a worse short-term patient-centered outcome.

Multicenter Study
Elevated serum S100B protein and neuron-specific enolase levels in carbon monoxide poisoning.
Carbon monoxide (CO) poisoning causes cerebral and generalized hypoxia. This study aimed to assess the possible use of serum glial marker S100B protein and neuron-specific enolase (NSE) as biochemical markers of hypoxic brain damage in acute CO poisoning. ⋯ Elevated serum S100B and NSE levels were associated with loss of consciousness in CO poisoning in this series of patients. Serum S100B and NSE may be useful markers in the assessment of clinical status in CO poisoning.
