Lactate Clearance Predicts Survival Among Patients in the Emergency Department with Severe Sepsis.

Introduction: Lactate clearance has been implicated as a predictor of mortality among emergency department (ED) patients with severe sepsis or septic shock. We aimed to validate prior studies showing that lactate clearance during the ED stay is associated with decreased mortality.

Methods: Retrospective dual-centered cross-sectional study using patients identified in the Yale-New Haven Hospital Emergency Medicine sepsis registry with severe sepsis or septic shock who had initial lactate levels measured in the ED and upon arrival (<24 hours) to the hospital floor.

Prehospital Evaluation of Effusion, Pneumothorax, and Standstill (PEEPS): Point-of-care Ultrasound in Emergency Medical Services.

Introduction: In the United States, there are limited studies regarding use of prehospital ultrasound (US) by emergency medical service (EMS) providers. Field diagnosis of life-threatening conditions using US could be of great utility. This study assesses the ability of EMS providers and students to accurately interpret heart and lung US images.

Profile of daily life in children with brain tumors: an assessment of health-related quality of life.

Purpose: The survival of children with CNS tumors approaches 70%, yet health-related quality of life (HRQOL) has not been investigated rigorously in this population. We aimed to show that universal assessment of HRQOL could be obtained easily by using the PedsQL 4.0 and to provide a composite profile of their daily lives.
