Effectiveness of Outpatient Intravenous Diuretic Therapy for Treatment of Worsening Heart Failure (OUTPATIENT-WHF)

Study Overview
=================
Brief Summary
-----------------
The purpose of the OUTPATIENT-WHF study is to characterize the effectiveness of outpatient intravenous diuretic therapy as a treatment for worsening heart failure.

Detailed Description
-----------------
The purpose of this study is to determine whether treating certain patients with worsening heart failure as an outpatient with intravenous and oral medications can work just as well as treating patients in the hospital. Participants who enter into the study and meet eligibility criteria will be randomly chosen to either get intravenous diuretic like Lasix in the clinic and get outpatient care, versus directly admitted to the hospital to receive intravenous diuretic and normal hospital care.

Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: ≥18 years of age Presentation to a Duke outpatient clinic with heart failure requiring IV diuretics, as per clinician judgement Able to provide signed informed consent Successful completion of EuroQOL-5 dimensions survey Exclusion Criteria: Managing clinician without equipoise for initial outpatient treatment strategy versus initial hospitalization-based treatment strategy for heart failure, and decline to accept randomization. Patient without equipoise for initial outpatient treatment strategy versus initial hospitalization-based treatment strategy for heart failure, and decline to accept randomization.

| Health status as measured by EuroQOL-5 dimensions (EQ5D) utility index | The EQ5D utility index consists of 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has five response categories (no problems, slight problems, moderate problems, severe problems, and extreme problems), from which a single EQ-5D index score can be calculated ranging from 0 (dead) to 1 (perfect health). | 30 days | 
| Health status as measured by EuroQOL-5 dimensions (EQ5D) visual analog scale (VAS) | The EQ5D VAS measures one's self-perceived health today on a vertical scale from 0 (worst imaginable health) to 100 (best imaginable health) on which participants have to indicate their current health. | 30 days |
