Measurement of adherence to clinical standards has become increasingly important to the practice of emergency medicine (EM). In recent years, along with a proliferation of evidence-based practice guidelines and performance measures, there has been a movement to incorporate measurement into reimbursement strategies, many of which affect EM practice. On behalf of the Society for Academic Emergency Medicine (SAEM) Guidelines Committee 2009-2010, the purposes of this document are to: 1) differentiate the processes of guideline and performance measure development, 2) describe how performance measures are currently and will be used in pay-for-performance initiatives, and 3) discuss opportunities for SAEM to affect future guideline and performance measurement development for emergency care. Specific recommendations include that SAEM should: 1) develop programs to sponsor guideline and quality measurement research; 2) increase participation in the process of guideline and quality measure development, endorsement, and maintenance; 3) increase collaboration with other EM organizations to review performance measures proposed by organizations outside of EM that affect emergency medical care; and 4) answer calls for participation in the selection and implementation of performance measures through The Joint Commission and the Centers for Medicare and Medicaid Services (CMS).

The accurate noninvasive assessment of preload in emergency department (ED) patients remains elusive. Point-of-care ultrasound (US) imaging, particularly evaluation of the inferior vena cava (IVC), has been shown to be qualitatively helpful. Doppler and tissue Doppler are now routinely available on ED US equipment, but few studies have looked at the correlation of dynamic changes in these parameters in a controlled model of hypovolemia. Our objective was to examine the correlation of Doppler parameters to simulated volume loss in healthy subjects using a lower-body negative pressure (LBNP) model and to compare these measurements to commonly used IVC measurements of preload. ⋯ In this pilot study of healthy subjects, tissue Doppler assessment of early diastolic filling correlated most strongly with simulated hypovolemia.

This experimental study aimed to assess the changes in the levels of serum ischemia-modified albumin (IMA) and interleukin-6 (IL-6) by time in cases of acute mesenteric ischemia due to superior mesenteric artery occlusion. ⋯ IMA may be helpful as a marker in the diagnosis of acute mesenteric ischemia; however, its diagnostic value and use as a routine biochemical test should be assessed in further studies.
