OUTpatient Intravenous LASix Trial in Reducing Hospitalization for Acute Decompensated Heart Failure — OUTLAST  

Heart Failure Clinical Trial

Official title: OUTpatient Intravenous LASix Trial in Reducing Hospitalization for ADHF (OUTLAST)

Status Completed

Clinical Trial Summary

Single-center, prospective double-blinded randomized control trial to evaluate the the feasibility, efficacy and safety of outpatient IV diuretic therapy in treatment of heart failure.

Clinical Trial Description

Patients were randomized by a clinical pharmacist with the ratio of 1:1:1 into 3 groups: standard of care control arm (Group 1), IV placebo infusion (Group 2), and IV furosemide infusion (Group 3).Patients in Group 2 and 3 received a comprehensive Heart Failure (HF)-care protocol that included bi-weekly clinic visits for dose-adjusted IV-diuretics, medication adjustment and education. Patients, nurses and treating physicians were blinded to the randomization. Patients in Group 1 received standard of care treatment per heart failure guidelines at the discretion of the primary cardiologist involved in the patient's care.8 Patients in Group 2 received IV saline infusion (20-40 ml) concentrated by the pharmacist to minimize fluid intake. Patients in Group 3 received IV furosemide calculated by the pharmacist to be equivalent or higher in dose compared to the patient's home oral dose. The dose assignments were categorized into low dose (20 mg bolus with 20 mg/hour infusion sessions and 2 ml saline), intermediate dose (40 mg bolus with 40 mg/hour infusion sessions and 4 ml saline) and high dose (80 mg bolus with 80 mg/hour infusion sessions). The infusions were continuous over 3 hours, biweekly over a one-month period. Infusions were held at the discretion of the physician utilizing a written protocol (creatinine 25% above baseline, Systolic Blood Pressure(SBP) <80 mmHg or symptoms of presyncope). Patients in both Groups 2 and 3 resumed all of their oral home medications for HF post infusion visits per standard of care. ;
