Implementation of guideline-directed medical therapy (GDMT) for heart failure with reduced ejection fraction (HFrEF) remains incomplete. Non-cardiovascular hospitalization may present opportunities for GDMT optimization. We assessed the efficacy and durability of a virtual, multidisciplinary 'GDMT Team' on medical therapy prescription for HFrEF.
A TOC pharmacist intervention improved the quality and safety of care across both inpatient and ambulatory settings for high-risk cardiovascular patients at our institution.
The prevalence of DRI is high even among HF patients managed in a subspecialty cardiovascular practice. Pharmacists in this setting play a vital role in more effectively resolving DRI.
Patients with renal impairment require dose adjustments for direct oral anticoagulants (DOACs), though there is uncertainty regarding their use in severe chronic kidney disease. Inappropriately dosed DOACs may increase risk of ischemic events when under-dosed, or risk of bleeding when over-dosed. The purpose of this study was to describe DOAC selection, dosing strategies, and associated clinical outcomes in patients with moderate to severe renal impairment at our institution. This was a single-center retrospective analysis of adult outpatients with moderate to severe renal impairment (estimated creatinine clearance <50 mL/min, including need for hemodialysis) who were prescribed a DOAC by a cardiologist between June 1, 2015 and December 1, 2018. Outcomes evaluated included the percentage of patients who received appropriate and inappropriate DOAC dosing, prescriber reasons for inappropriate DOAC dosing if documented, and incidence of thrombotic and bleeding events. A total of 207 patients were included. Overall, 61 (29.5%) patients received inappropriate dosing, with 43 (70.5%) being under-dosed and 18 (29.5%) being over-dosed as compared to FDA-labeled dosing recommendations for atrial fibrillation or venous thromboembolism (VTE). By a median follow-up duration of 20 months, stroke occurred in 6 (3.3%) patients receiving DOACs for atrial fibrillation, and VTE occurred in 1 (4.3%) patient receiving a DOAC for VTE. International Society on Thrombosis and Haemostasis major or clinically relevant nonmajor bleeding occurred in 25 (12.1%) patients. Direct oral anticoagulants were frequently prescribed at off-label doses in patients with moderate to severe renal impairment, with a tendency toward under-dosing.
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.
