Details and patient eligibility

About

The primary objective of the study is to develop, implement, and evaluate a site-specific clinical pathway for at-home treatment of eligible patients presenting to the clinic with worsening heart failure.

The secondary objectives are:

1. To evaluate patient factors related to parenteral decongestion at home.
2. To evaluate the safety and device operation of Lasix ONYU treatment under circumstances that mimic real-world use.
3. To identify opportunities for process improvement before the routine implementation of the new clinical pathway.

Full description

We will conduct an open-label, non-comparative, real-world study to evaluate the effectiveness and feasibility of at-home decongestion treatment using Lasix ONYU in patients with worsening heart failure (WHF). During a clinical visit at the UF Heart Failure Clinic, Emergency Department, or Clinical Decision Unit, we will assess whether a patient meets eligibility criteria for the study.

Enrollment: 100 estimated patients

Sex: All

Ages: 18 to 80 years old

   2. JVP > 10cmH20
   3. Presence of S3
   4. LE Edema
   5. Weight gain of > 5lbs in the past 5 days

4. Failed oral uptitration of loop diuretic over the prior 5 days or presented with symptoms too advance to justify additional oral uptitration attempts to resolve congestion symptoms.

5. Expected to require a minimum of three days of parenteral diuretic treatment

6. Written informed consent

7. Able and willing to operate Lasix ONYU and comply with study requirements or has a caregiver who can assume these roles.

Exclusion criteria

6. Pregnant or breastfeeding
7. Unable to comply with clinic-required follow up procedure
8. Baseline chronic renal disease with CKD Stage V
