Deciding which add-on treatments and IV furosemide doses to use for people hospitalized with heart failure

Preparatory Work for a Multi-arm, Multi-stage Trial of Adjunctive Treatments in Patients Hospitalised With Heart Failure (Pre-MAMMOTH-HF)

Observational Hull University Teaching Hospitals NHS Trust · NCT07281040

This project will gather clinician and patient input to decide which add-on treatments, doses, and outcomes to test for people recently hospitalized with heart failure.

What this trial studies

This observational preparatory project combines an online clinician survey, a modified-Delphi expert panel, and a patient-and-carer advisory group to define the design of a future randomized trial. Clinicians (doctors, nurses, pharmacists) at sites across the UK will complete a Qualtrics survey about acceptability of adjuncts, willingness to randomize, and realistic recruitment capacity. An expert panel of ~20–25 clinicians and allied health professionals will use the evidence and a modified Delphi process to recommend adjunct selection, comparator IV furosemide doses, and primary/secondary outcomes. A patient-and-carer panel of people recently hospitalized for heart failure will advise on meaningful endpoints and acceptability of interventions.

Who should consider this trial

Good fit: People who were hospitalized with heart failure within the past six months (or their carers) and who can take part in online group discussions in English.

Not a fit: Patients who were not recently hospitalized, cannot join online English discussions, or need translation/support to participate are unlikely to directly benefit from this preparatory project.

Why it matters

Potential benefit: If successful, this work could enable a well-designed randomized trial that identifies safer or more effective add-on diuretic strategies to speed recovery and reduce rehospitalizations after heart failure hospitalization.

How similar studies have performed: Delphi panels and clinician/patient surveys are commonly used to shape trial design and endpoints and have improved relevance in other cardiovascular research, though specific adjunctive strategies for acute heart failure remain relatively under-tested.
