Randomized Controlled Trial Comparative Study Clinical Trial
Ethical dilemmas in a randomized trial of asthma treatment: can Bayesian statistical analysis explain the results?
The original objective was to determine whether the use of bilevel positive airway pressure (BiPAP) ventilation would reduce the need for endotracheal intubation, the length of hospital stay, and hospital charges in patients with status asthmaticus. The development of physician treatment bias made patient enrollment difficult. The article subsequently describes the use of Bayesian statistics to explain study results when this bias occurs. ⋯ In this study, BiPAP appeared to have no deleterious effects in patients with status asthmaticus, with a trend toward decreased endotracheal intubation rate, decreased length of hospital stay, and decreased hospital charges. Although further study with more patients is needed to determine the clinical and statistical significance of this intervention, ethical concerns regarding withholding BiPAP treatment from the patients in the control group forced a premature termination of the study in the authors' institution.

Comparative Study
Emergency medicine resident patient care documentation using a hand-held computerized device.
To determine whether emergency medicine (EM) resident documentation of procedures, patient encounters, and patient follow-ups improved after implementation of a personal digital assistant (PDA) hand-held recording system. ⋯ Use of a hand-held PDA was associated with an increase in first-year EM resident documentation in three of 20 procedures and a decrease in one procedure and the number of unstable surgical pediatric patient resuscitations. The overall time savings in constructing a resident procedure database, as well as the other uses of the PDAs, may make transition to a hand-held computer-based procedure log an attractive option for EM residencies.

Reliable and valid measures of pain are needed to advance research initiatives on appropriate and effective use of analgesia in the emergency department (ED). The reliability of visual analog scale (VAS) scores has not been demonstrated in the acute setting where pain fluctuation might be greater than for chronic pain. The objective of the study was to assess the reliability of the VAS for measurement of acute pain. ⋯ Reliability of the VAS for acute pain measurement as assessed by the ICC appears to be high. Ninety percent of the pain ratings were reproducible within 9 mm. These data suggest that the VAS is sufficiently reliable to be used to assess acute pain.

Critics of the use of clinical practice guidelines (CPGs) in an emergency department (ED) setting believe that they are too cumbersome and time-consuming, but to the best of the authors' knowledge, potential barriers to CPG adherence in the ED have not been prospectively evaluated. ⋯ Clinical practice guidelines can be used successfully in the pediatric ED and provide a more efficient management and treatment approach to acute exacerbations of childhood asthma. With a systematic and concise CPG, barriers to adherence in a pediatric ED appear to be minimal, with the exception of using PEF in the routine ED assessment.

Comparative Study
Incidence of pericardial effusion in patients presenting to the emergency department with unexplained dyspnea.
To evaluate the frequency of pericardial effusion in patients presenting to the emergency department (ED) with unexplained, new onset dyspnea. ⋯ While limited by small numbers, these preliminary data suggest that patients with unexplained dyspnea should be checked for pericardial effusion when bedside ED ultrasound is available.
