Multicenter Study
Predictors of patient length of stay in 9 emergency departments.
Prolonged emergency department (ED) length of stay (LOS) is linked to adverse outcomes, decreased patient satisfaction, and ED crowding. This multicenter study identified factors associated with increased LOS. ⋯ Length of stay was increased on days with higher percentage daily admissions, higher elopements, higher periods of ambulance diversion, and during weekdays, whereas LOS was decreased on days with higher numbers of discharges and weekends. This is the first study to demonstrate this association across a broad group of hospitals.

Survival after in-hospital cardiac arrest (CA) has been reported to be surprisingly low without any major improvement during the last decade. ⋯ An intervention within 1 single hospital (systematic training of all health care professionals in cardiopulmonary resuscitation and implementation of automated external defibrillators) did not reduce treatment delay or increase overall survival. Our results, however, suggest indirect signs of an improved cerebral function among survivors.

Adenosine is widely used for the treatment of supraventricular tachycardias for its efficacy and excellent safety, but it has been reported to precipitate severe bronchospasm in patients with pulmonary disease. The drug is therefore contraindicated in asthmatic subjects and should be used with caution in patients with chronic obstructive pulmonary disease. Nevertheless, true bronchospasm is rare and should be distinguished from the much more common occurrence of dyspnea, only as a symptom and without respiratory compromise, which is benign and transient. ⋯ He was treated with oxygen and inhaled and intravenous steroids, but dyspnea and bronchospasm resolved only after intravenous aminophylline. The arrhythmia recurred and was finally terminated by intravenous flecainide. Although dyspnea after adenosine administration is usually a transient, benign phenomenon, physicians should be alert to the presence of objective signs of respiratory distress, which should prompt immediate treatment, even in subjects without previous history of pulmonary disease.

Knee dislocations are rare injuries typically associated with severe traumatic mechanisms. We report 2 cases of morbidly obese patients who had complete knee dislocations after falls from standing height. Both cases resulted in significant morbidity secondary to popliteal artery injury. Emergency physicians need to maintain a high index of suspicion for knee dislocations and should be aware of atypical presentations from minor trauma in the obese population.

The aim of this study was to assess the performance of 3 different influenza-like illness (ILI) case definitions, adopted by the European (European-CDC), USA (USA-CDC), and Taiwan Centers for Disease Prevention and Control (Taiwan-CDC), as screening tools for influenza during the 2009 H1N1 pandemic. ⋯ First-line physicians should recognize the advantage and limitation of different ILI case definitions in influenza screening, especially confronted by pandemic or highly pathogenic avian influenza in the future.
