Protokolloitava korkean virtauksen nenäkanuunan vieroitus aikuispotilailla: Porrastettu kiilaklusterisatunnaistutkimus (PRO-WEAN HFNC)

High-flow nasal cannula (HFNC) is a type of oxygen therapy commonly used in adults with breathing problems. While HFNC can help patients avoid breathing tubes and improve oxygen levels, there is no standard method for deciding how and when to reduce and stop this therapy once a patient improves. In many hospitals, these decisions vary from clinician to clinician.

This study will compare usual care with a standardized step-by-step plan for reducing HFNC support. Eight hospitals will participate and will switch from usual care to the standardized plan at different time points during the study.

The main goal is to determine whether the standardized weaning plan increases the number of patients who can successfully stop HFNC within 5 days. The study will also evaluate how long patients remain on HFNC, whether they need additional breathing support, and how long they stay in the hospital.

The results may help develop clearer guidance for safely and efficiently stopping HFNC therapy.

Yksityiskohtainen kuvaus

High-flow nasal cannula (HFNC) therapy has become a standard treatment for acute hypoxemic respiratory failure. Although evidence supports its use for improving oxygenation and reducing intubation risk, guidance on how to discontinue HFNC remains limited. Current weaning practices are highly variable across institutions and clinicians. This variability may contribute to either premature discontinuation, leading to respiratory deterioration, or prolonged therapy, which may delay ICU discharge and increase healthcare utilization.

This trial evaluates implementation of a standardized HFNC weaning protocol across multiple hospitals using a stepped-wedge cluster randomized design. The intervention focuses on structured, progressive reduction of HFNC flow and fraction of inspired oxygen (FiO₂), with predefined criteria for discontinuation and re-escalation of support.

The stepped-wedge approach allows sequential implementation of the protocol across participating hospitals while accounting for secular trends and inter-site practice variability. The study is designed to determine whether protocolized weaning improves efficiency and clinical outcomes compared with usual care.

Findings from this trial are intended to inform evidence-based guidance for HFNC liberation strategies in adult patients with acute hypoxemic respiratory failure.

Active Comparator: Usual Care HFNC Weaning

During this phase, high-flow nasal cannula (HFNC) weaning and discontinuation are performed according to local standard practice without a mandated protocol. Decisions regarding reduction of flow and fraction of inspired oxygen (FiO₂), transition to conventional oxygen therapy, and re-escalation of support are made at the discretion of the treating clinical team.
