Association between a positive ED FAST examination and therapeutic laparotomy in normotensive blunt trauma patients.
Although a positive FAST (focused assessment with sonography for trauma) examination in hypotensive blunt trauma patients generally suggests the need for emergent laparotomy, this finding's significance in normotensive trauma patients is unclear. We tested the association between a positive FAST and the need for therapeutic laparotomy in normotensive blunt trauma patients. This was a retrospective cohort analysis of consecutive normotensive blunt trauma patients presenting to two trauma centers. ⋯ Thirty-seven percent of patients with a positive FAST required therapeutic laparotomy vs. 0.5% with a negative FAST. Among normotensive blunt trauma patients, there was a strong association between a positive FAST and the need for therapeutic laparotomy. Very few normotensive patients with a negative FAST required therapeutic laparotomy.

This study explores the effects of minimizing Emergency Department (ED) bypass on individual hospital's ED census, ambulance transports, and admissions. Five hospitals in a geographic area collected data over 3 weeks. The first and third week represented controls, whereas the second week hospitals minimized their usage of bypass. ⋯ There were several statistical shifts in the proportion of ambulance runs and admissions seen by individual hospitals. Clinically, these shifts in patients were minor and within ED capacity. Hospitals in a given geographic area may successfully reduce the number of hours on bypass with possible minor shifting in the number of ambulance runs and admissions that are within ED capacity.

Can urine dipstick be used as a surrogate for serum creatinine in emergency department patients who undergo contrast studies?
Contrast-induced nephropathy (CIN) is a complication associated with contrasted computed tomography (CT). Elevated creatinine (Cr) is often used to screen for CIN. This study evaluates dipstick urinalysis (Udip) detection of Cr > 1.5 mg/dL. ⋯ Thirty-five patient visits (among 26 patients) had negative urine dip and Cr > 1.5 mg/dL, but each reported at least one of the following at triage: prior renal disease, hypertension, diabetes, congestive heart failure, or age > 60 years. Udip is a sensitive screening test, but alone is not accurate enough to predict patients at potential risk for CIN (Cr > 1.5 mg/dL). However, combining Udip results with risk factor screening may allow a rapid method for predicting which patients may safely undergo contrast CT scanning in the ED, but this needs prospective evaluation.

Factors associated with antimicrobial resistance and mortality in pneumococcal bacteremia.
We conducted a multicenter, retrospective cohort study of patients with Streptococcus pneumoniae bacteremia to determine factors associated with antibiotic resistance and mortality. Risk factors were identified using multivariate logistic regression. There were 1574 patients at 34 sites enrolled. ⋯ Factors associated with macrolide non-susceptibility include: > 24 h of antibiotic therapy at time of the index culture (odds ratio [OR] 4.0), residing in southern U. S. (OR 1.7), and having an antibiotic allergy (OR 1.7). Harboring an antibiotic non-susceptible strain (OR 1.4) and male sex (OR 1.4) were associated with increased risk of mortality, whereas black race (OR 0.6) and evidence of focal infection (OR 0.6) were associated with decreased risk.

The purpose of this study was to describe the violence experienced by Emergency Department (ED) workers from patients and visitors during the 6 months before the survey. Two hundred forty-two employees at five hospitals who came in direct contact with patients or visitors completed a survey. The study found that most workers had been verbally harassed by patients or visitors at least once. ⋯ There were significant relationships among violent experiences, feelings of safety, and job satisfaction. ED workers are at high risk for violence, and efforts are needed to decrease the incidence of violence. Such efforts are likely to have a positive impact on job satisfaction and retention of ED workers.
