Randomized Controlled Trial Multicenter Study Comparative Study
A multicenter randomized controlled trial comparing central laboratory and point-of-care cardiac marker testing strategies: the Disposition Impacted by Serial Point of Care Markers in Acute Coronary Syndromes (DISPO-ACS) trial.
Point-of-care testing reduces time to cardiac marker results in patients evaluated for acute coronary syndromes, yet evidence this translates to a decreased length of stay is lacking. We hypothesized that point-of-care testing decreases length of stay in patients being evaluated for acute coronary syndromes in the emergency department (ED). ⋯ The effect of point-of-care testing on length of stay in the ED varies between settings. At one site, point-of-care testing decreased time to admission, whereas at another, point-of-care testing increased time to discharge. Potential effects of point-of-care testing on patient throughput should be considered in the full context of ED operations.

Randomized Controlled Trial
A randomized trial of diphenhydramine as prophylaxis against metoclopramide-induced akathisia in nauseated emergency department patients.
Akathisia, an adverse effect observed at times after administration of parenteral metoclopramide, is an unpleasant symptom complex characterized by restlessness and agitation. Some try to limit the development of akathisia by coadministering diphenhydramine when using parenteral metoclopramide. The goal of this investigation is to determine whether concomitant administration of diphenhydramine 25 mg decreased the rate of development of akathisia after administration of 10 mg or 20 mg of intravenous metoclopramide. ⋯ Routine prophylaxis with diphenhydramine to prevent akathisia is unwarranted when intravenous metoclopramide is administered over 15 minutes. For patients administered 20 mg of metoclopramide, prophylactic diphenhydramine may decrease subjective restlessness.
