Clinical policy: critical issues in the evaluation and management of adult patients in the emergency department with asymptomatic elevated blood pressure.
This clinical policy from the American College of Emergency Physicians is the revision of a 2006 policy on the evaluation and management of adult patients with asymptomatic elevated blood pressure in the emergency department.1 A writing subcommittee reviewed the literature to derive evidence-based recommendations to help clinicians answer the following critical questions: (1) In emergency department patients with asymptomatic elevated blood pressure, does screening for target organ injury reduce rates of adverse outcomes? (2) In patients with asymptomatic markedly elevated blood pressure, does emergency department medical intervention reduce rates of adverse outcomes? A literature search was performed, the evidence was graded, and recommendations were given based on the strength of the available data in the medical literature.

Multicenter Study Comparative Study
Examining renal impairment as a risk factor for acute coronary syndrome: a prospective observational study.
This study seeks to examine whether the finding of an abnormal estimated glomerular filtration rate (eGFR) in the emergency department (ED) was associated with acute coronary syndrome in the population of patients presenting for investigation of chest pain. ⋯ There is an independent association between eGFR and acute coronary syndrome risk in patients presenting to the ED with chest pain; this association is independent of age, traditional cardiac risk factors, medical history, troponin level, and ECG findings. Reduced eGFR should be considered an acute coronary syndrome risk factor, and clinicians should maintain high clinical suspicion for acute coronary syndrome in patients with abnormal renal function results regardless of whether they have known kidney disease, traditional acute coronary syndrome risk factors, or abnormal diagnostic test results. Risk stratification tools should include reduced eGFR as a high-risk feature.

This study seeks to determine whether health information exchange reduces repeated diagnostic imaging and related costs in emergency back pain evaluation. ⋯ Health information exchange use is associated with 64% lower odds of repeated diagnostic imaging in the emergency evaluation of back pain. Health information exchange effect on estimated costs was negligible. More studies are needed to evaluate specific strategies to increase health information exchange use and further decrease potentially unnecessary diagnostic imaging and associated costs of care.
