Early Cold Stored Platelet Transfusion Following Severe Injury: A Randomized Clinical Trial.

OBJECTIVE: To determine the feasibility, efficacy, and safety of early cold stored platelet transfusion compared to standard care resuscitation in patients with hemorrhagic shock. SUMMARY BACKGROUND DATA: Data demonstrating the safety and efficacy of early cold stored platelet transfusion are lacking following severe injury. METHODS: A phase 2, multicenter, randomized, open label, clinical trial was performed at five U.S. trauma centers. Injured patients at risk of large volume blood transfusion and the need for hemorrhage control procedures were enrolled and randomized. The intervention was the early transfusion of a single apheresis cold stored platelet unit, stored for up to 14 days vs. standard care resuscitation. The primary outcome was feasibility and the principal clinical outcome for efficacy and safety was 24-hour mortality. RESULTS: Mortality at 24 hours was 5.9% in patients who were randomized to early cold stored platelet transfusion compared to 10.2% in the standard care arm (difference, -4.3%; 95% CI, -12.8% to 3.5%; P=0.26). No significant differences were found for any of the prespecified ancillary outcomes. Rates of arterial and/or venous thromboembolism and adverse events did not differ across treatment groups. CONCLUSIONS AND RELEVANCE: In severely injured patients, early cold stored platelet transfusion is feasible, safe and did not result in a significant lower rate of 24-hour mortality. Early cold stored platelet transfusion did not result in a higher incidence of arterial and/or venous thrombotic complications or adverse events. The storage age of the cold stored platelet product was not associated with significant outcome differences.

Implementation of an Assault Prevention Quality Improvement Initiative in an Urban Emergency Department.

BACKGROUND: Emergency department (ED) health care workers experience high rates of workplace violence (WPV). LOCAL PROBLEM: Patient-to-staff physical assaults at an urban, academic adult ED ranged between 1 and 5 per month, with a rate of 0.265 per 1000 patient visits. METHODS: A quality improvement initiative, guided by the Social Ecological Model framework that contextualized WPV in the ED setting, informed the development of a Risk for Violence Screening Tool (RVST) to screen adult patients presenting to the ED. INTERVENTIONS: Plan-Do-Study-Act cycles were utilized to implement a violence prevention bundle that incorporated the RVST, an alert system, and focused assault reduction strategies. RESULTS: Patient-to-staff physical assaults decreased to a rate of 0.146 per 1000 patient visits. CONCLUSIONS: Risk for violence screening, an alert system, and assault prevention strategies provide opportunities for nurse leaders to promote ED workplace safety.
