Multicenter Study
Physician clinical impression does not rule out spontaneous bacterial peritonitis in patients undergoing emergency department paracentesis.
We determine whether clinical characteristics and physician assessment are useful in the exclusion of spontaneous bacterial peritonitis in emergency department (ED) patients with ascites requiring paracentesis. ⋯ Clinical characteristics and physician assessment were insufficient in the diagnosis or exclusion of spontaneous bacterial peritonitis in the ED patient undergoing diagnostic or therapeutic paracentesis. This finding supports routine laboratory fluid analysis after ED paracentesis.

Multicenter Study
Assessment of the reliability of the Johns Hopkins/Agency for Healthcare Research and Quality hospital disaster drill evaluation tool.
The Joint Commission requires hospitals to implement 2 disaster drills per year to test the response phase of their emergency management plans. Despite this requirement, there is no direct evidence that such drills improve disaster response. Furthermore, there is no generally accepted, validated tool to evaluate hospital performance during disaster drills. We characterize the internal and interrater reliability of a hospital disaster drill performance evaluation tool developed by the Johns Hopkins University Evidence-based Practice Center, under contract from the Agency for Healthcare Research and Quality (AHRQ). ⋯ We found a high degree of internal reliability in the AHRQ instrument's items, suggesting the underlying construct of hospital preparedness is valid. Conversely, we found substantial variability in interrater reliability, suggesting that the instrument needs revision or substantial user training, as well as verification of interrater reliability in a particular setting before use.

Randomized Controlled Trial Multicenter Study
Out-of-hospital continuous positive airway pressure ventilation versus usual care in acute respiratory failure: a randomized controlled trial.
Continuous positive airway pressure ventilation (CPAP) in appropriately selected patients with acute respiratory failure has been shown to reduce the need for tracheal intubation in hospital. Despite several case series, the effectiveness of out-of-hospital CPAP has not been rigorously studied. We performed a prospective, randomized, nonblinded, controlled trial to determine whether patients in severe respiratory distress treated with CPAP in the out-of-hospital setting have lower overall tracheal intubation rates than those treated with usual care. ⋯ Paramedics can be trained to use CPAP for patients in severe respiratory failure. There was an absolute reduction in tracheal intubation rate of 30% and an absolute reduction in mortality of 21% in appropriately selected out-of-hospital patients who received CPAP instead of usual care. Larger, multicenter studies are recommended to confirm this observed benefit seen in this relatively small trial.

Emergency medical services (EMS) provide care to acutely ill or injured patients in settings less controlled than other health care environments. Although reports describing individual EMS adverse events exist, few broader descriptions exist. The objective of the study is to characterize the types, frequencies, and outcomes of adverse events associated with insurance tort claims against EMS providers. ⋯ Emergency vehicle crashes and patient handling mishaps were the most common adverse events associated with tort claims against EMS agencies. Clinical management and other incidents were less common. This effort highlights potential areas for improving EMS operations and care.
