Background:The class III antiarrhythmic sotalol is renally eliminated with a dose-related propensity to cause adverse drug reactions (ADR) potentially leading to life-threatening arrhythmias. Although product labeling recommends once daily dosing in patients with renal impairment, twice daily dosing is commonly utilized. This study evaluates the safety of this practice. Methods:This retrospective, observational study examined renally impaired patients with atrial fibrillation or atrial flutter admitted for sotalol initiation from July 1, 2012-December 31, 2014, then for up to 20 months after initiation. Primary endpoints included rates of ADR and therapy changes due to ADR. Secondary endpoints included therapy changes due to arrhythmia recurrence, admissions due to arrhythmia recurrence, and therapy changes for any cause. Results: Analysis included 134 patients with an average creatinine clearance of 51 ml/min, followed over a median of 170 days. Length of stay averaged 3 days with ADR occurring in 53.7% of patients, most commonly QT prolongation or bradycardia. Therapy change due to ADR occurred in 45.5% of patients (n=61). Therapy change due to arrhythmia recurrence occurred in 23.1% (n=31), admission due to arrhythmia recurrence occurred in 24.6% (n=33), and therapy change for any cause occurred in 74.6%(n=100). Conclusion:Initiating sotalol twice daily in renally impaired patients results in ADR and therapy change rates consistent with rates seen in clinical practice for non-renally impaired patients, with minimal length of stay.This practice may be reasonable when initiated in the acute care setting with subsequent outpatient monitoring, however further study is needed.

Background Storage pool deficiency (SPD) is a rare bleeding disorder characterized by reduction in the number of delta granules within platelets, interfering with hemostasis. Current literature lacks well-designed studies from which to draw concrete conclusions regarding pre-procedural management of bleeding complications. Objective: The purpose of this study is to describe bleeding and safety outcomes of SPD patients receiving either pre-procedural platelet transfusions or platelet-sparing regimens. Methods: An exploratory retrospective cohort study was conducted among SPD patients, comparing major bleeding events between those who received platelet transfusion and those who received desmopressin, tranexamic acid, and/or aminocaproic acid within 24 hours prior to procedure. Results: Rates of major bleeding were not found to be higher among patients who received a platelet-sparing regimen [platelet-sparing: 2/25 (8%); platelet transfusion: 2/29 (6.9%); P = .99]. Incidence of non-major bleeding was higher in the platelet transfusion group, but this was not statistically significant [platelet-sparing: 0/25 (0%); platelet transfusion: 3/29 (10.3%); P = .24]. Treatment-related adverse effects were observed following 8 of 54 procedures (14.8%). Conclusion: Use of a platelet-sparing regimen was not associated with a significantly higher incidence of major or non-major bleeding events. Future prospective trials are recommended to compare outcomes between therapies.

Background: Hemophilia treatment centers (HTC) are multidisciplinary clinics that serve as medical homes for patients with hemophilia and other bleeding or clotting disorders. Traditionally, hemophilia treatment center teams have included hematologists, social workers, nurse coordinators, physical therapists, and in some instances, other healthcare professionals. Objective: This report describes the role of clinical pharmacy services added at 2 HTCs. Method: Retrospective review of services provided by pharmacists integrated into the care team conducted at 2 HTCs. Conclusions: Pharmacists have the knowledge and training to positively contribute to the care of hemophilia treatment center patients. Specifically, with expertise in therapeutic drug monitoring, pharmacokinetics and patient counseling, pharmacists have the ability to manage the cost of care by promoting adherence, minimizing emergency department visits, and assisting providers in formulating optimal treatment plans to improve care for this patient population.
