Comparative Study
Direct comparison of the diagnostic accuracy of fifty protein biological markers of pulmonary embolism for use in the emergency department.
Pulmonary embolism (PE) is associated with abnormal concentrations of many proteins involved in inflammation, hemostasis, and vascular injury. The authors quantified the diagnostic accuracy of a battery of protein biological markers for the detection of PE in emergency department (ED) patients. ⋯ From 50 candidate biological markers, only D-dimer, CRP, and MPO demonstrated sufficient diagnostic accuracy to suggest potential utility as biological marker of PE.

The objective was to study the association between factors related to emergency department (ED) crowding and patient satisfaction. ⋯ A poor ED service experience as measured by ED hallway use and prolonged boarding time after admission are adversely associated with ED satisfaction and predict lower satisfaction with the entire hospitalization. Efforts to decrease ED boarding and crowding might improve patient satisfaction.

Understanding the impact of overcrowding in pediatric emergency departments (PEDs) on quality of care is a growing concern. Boarding admitted patients in the PED and increasing emergency department (ED) visits are two potentially significant factors affecting quality of care. ⋯ ED boarding time and ED daily census show independent associations with increasing overall LOS, time to triage, time to physician, and number of patient elopements in a PED.

Despite little empiric evidence, mechanical ventilation (MV) in the setting of salicylate poisoning is considered by many to be harmful. When salicylate-poisoned patients are ventilated at conventional settings, the respiratory alkalosis is abolished, more salicylate is able to pass into the central nervous system (CNS), and neurotoxicity worsens. The objective of this study was to identify a relationship between MV, acidosis, and outcome in salicylate-poisoned patients. ⋯ Inadequate MV of patients with salicylate poisoning is associated with respiratory acidosis, acidemia, and clinical deterioration in this series of cases. This supports warnings about the danger of improper MV in patients with salicylate poisoning. A prospective study should be performed.
