The HiFAE trial
HiFAE (home high-flow therapy with oxygen to reduce acute exacerbations of COPD) is a randomised, controlled trial to evaluate the efficacy of home high-flow therapy with oxygen versus standard oxygen therapy in patients with COPD. This ongoing study is being conducted at 18 centres in France (N=406). The primary endpoint is the time to first hospital admission for AECOPD or death.
The EPiC Trial
EPiC (Exacerbation Prevention in COPD using home High Flow therapy) is a UK multi-centre, randomised, controlled trial to investigate the effect of home High-Flow Therapy (HFT) as an adjunct to usual medical care on admission-free survival following severe exacerbations of Chronic Obstructive Pulmonary Disease (COPD).
HFT is simple and easy-to-operate and delivers both clinical and patient outcome benefits in domiciliary use for COPD. HFT is currently used in the acute hospital setting in adults and is emerging as an option for long-term home use in COPD patients. 6,7
Patient comfort and quality of life
Patients with COPD receiving long-term HFT at home have shown preserved or improved QoL scores vs those receiving usual care, including LTOT alone.6,7 HFT also seems to be well tolerated by patients7 and supports patient comfort by improving mucociliary clearance and secretion management1 and reducing dyspnoea during high intensity exercise. 2-4
