Objectives Determine indication specific 4-Factor prothrombin complex concentrate (4FPCC) dosing strategies within a hospital system and subsequent effectiveness. Background: 4FPCC is FDA approved for reversal of vitamin K antagonists (VKA) for acute major bleeding or need for urgent surgery/invasive procedure. Since its approval, off label use has expanded to include direct oral anticoagulant reversal and perioperative hemostasis. Optimal dosing strategies remain controversial, and recent studies have evaluated fixed-dose regimens with lower doses than those recommended in product labeling. Methods/Materials: Retrospective cohort with manual chart review for patients who received 4FPCC spanning 2 years. Primary outcome was to characterize dosing. Secondary outcomes were INR normalization, hemostatic efficacy, in-hospital mortality, and renal function change. Results: Of the 300 patients evaluated, 80% received 4FPCC for anticoagulant reversal, with 66% of those for VKA and 34% for DOAC. The remaining 20% received 4FPCC for a non-reversal indication. Of the patients requiring anticoagulation reversal, 25% received doses lower than recommended and 6% received higher. 71% of patients received 4FPCC for life-threatening bleed, and 45% of them had intracranial hemorrhage. Higher mortality with higher than recommended doses was the only statistically significant secondary outcome ( P = .018). Conclusion: We found that lower doses than recommended were used in a significant number of patients. The higher than recommended doses group constituted a small proportion of patients and the higher mortality was attributed to patient acuity on presentation. Additional studies evaluating dosing approach are required to determine lowest effective dosing for various indications.
INTRODUCTION:The Intermountain Medical Center (IMED) emergency department (ED) has the highest volume of patients in Utah. With the surge of COVID-19 cases during the early portion of October 2020, there was an expected increase in complex patients. Emergency medicine pharmacist (EMP) services were requested to expand from the 0700 to 2300 staffing model to 24-hour coverage. The purpose of this study was to evaluate interventions completed by overnight EMPs and the associated potential cost avoidance (CA).
Guidelines recommend magnesium and defibrillation for Torsades de Pointes (TdP) treatment in pregnancy, both of which were unsuccessful at terminating our patient's recurrent ventricular arrhythmias. Both lidocaine and isoproterenol carry potential risks to mother and fetus, but the risk of congenital abnormalities is significantly lower compared to other antiarrhythmics such as amiodarone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
