Is this trial a fit for you?

Likely a good fit

Hospitals inpatients with a history of liver cirrhosis and a diuretic order (bumetanide or furosemide) placed within 24 hours of presentation.

Probably not a fit

Patients without circulatory or renal constraints that affect diuretic response, or those not experiencing volume overload, may not see a benefit.

What this trial studies

This is a phase 3, pragmatic interventional trial conducted at the University of Utah Hospital. It compares two loop diuretics, bumetanide and furosemide, in hospitalized patients with cirrhosis and volume overload. Eligible patients are those with a history of cirrhosis who have a diuretic order placed within 24 hours of hospital presentation, excluding those with contraindications or non-volume overload indications. The trial focuses on real-world diuresis outcomes and may inform which diuretic provides more effective fluid removal in this setting.

Why it matters

Potential benefit: If bumetanide proves more effective, patients could experience better fluid control and fewer complications from overload.

How similar studies have gone: Prior work suggests diuretic choice can impact natriuresis in cirrhosis, but this head-to-head phase 3 comparison is relatively novel.
