Observational Study
Gestalt for shock and mortality in the emergency department: A prospective study.
The diagnosis of shock in patients presenting to the emergency department (ED) is often challenging. We aimed to compare the accuracy of experienced emergency physician gestalt against Li's pragmatic shock (LiPS) tool for predicting the likelihood of shock in the emergency department, using 30-day mortality as an objective standard. ⋯ LiPS has a higher diagnostic accuracy than emergency physician gestalt for shock when compared against an outcome of 30-day mortality.

Currant jelly stool is a late manifestation of intussusception and is rarely seen in clinical practice. Other forms of GI bleeding have not been thoroughly studied and little is known about their respective diagnostic values. ⋯ Blood in stool, whether visible or tested by guaiac test has poor diagnostic performance in the evaluation of intussusception and is not independently predictive of intussusception. If the sole purpose of a rectal exam in these patients is for guaiac testing it should be reconsidered.

Observational Study
Implementation of Alere i Influenza A & B point of care test for the diagnosis of influenza in an emergency department.
This study aimed to evaluate the impact of implementing rapid point-of-care testing (POCT) with the Alere i Influenza A & B in an emergency department (ED) during an influenza epidemic. ⋯ The Alere i Influenza A & B POCT reduced the length of stay in ED, the hospitalization rates, and the number of additional diagnostic tests compared with standard of care testing.

Lactate and lactate clearance are being used as biomarkers in several critical conditions. The aim of this study was to examine the value of sixth hour lactate clearance in patients who were hospitalized with chronic obstructive pulmonary disease (COPD) exacerbations. ⋯ Lactate clearance can be evaluated as a useful marker in patients with COPD exacerbations. This study suggests that lactate monitoring in the ED has clinical benefits in addition to GOLD guidelines when deciding whether to discharge or hospitalize a patient.
