Comparative Study
Using queueing theory to increase the effectiveness of emergency department provider staffing.
Significant variation in emergency department (ED) patient arrival rates necessitates the adjustment of staffing patterns to optimize the timely care of patients. This study evaluated the effectiveness of a queueing model in identifying provider staffing patterns to reduce the fraction of patients who leave without being seen. ⋯ Timely access to a provider is a critical dimension of ED quality performance. In an environment in which EDs are often understaffed, analyses of arrival patterns and the use of queueing models can be extremely useful in identifying the most effective allocation of staff.

To determine whether the Mac-technique test can detect kinking of the chest tube upon thoracostomy tube placement. ⋯ On the basis of this study, a positive Mac-technique test is useful to detect chest tubes that are likely to be kinked after insertion and before securing.

To describe our experience with early goal-directed therapy (EGDT), corticosteroid administration, and recombinant human activated protein C (rhAPC) administration in patients with severe sepsis or septic shock and an Acute Physiology and Chronic Health Evaluation (APACHE) II score > or =25 in the emergency department (ED). ⋯ EGDT, corticosteroid administration, and rhAPC administration are feasible in the ED setting. While these evidence-based therapies individually have been shown to improve outcomes for patients with severe sepsis or septic shock, further studies are needed to examine their combined effectiveness during the early stages of this disease.
