Plain English Summary

Background and study aims
Chronic obstructive pulmonary disease (COPD) is a common and important problem. Patients with COPD may experience exacerbations, which are deteriorations in COPD symptoms, such as breathlessness, cough and/or sputum production. Exacerbations may be severe enough to lead to requiring hospital admission. During recovery from an exacerbation, patients can experience disabling breathlessness which limits their day-to-day activities. This can occur despite the usual care with medications, including inhalers, steroids and antibiotics for COPD. There is a technique called nasal high-flow that can improve breathlessness and reduce hospital admissions and frequency of exacerbations amongst certain patients with stable COPD.

This study is being carried out to determine whether using nasal high-flow at home in patients recovering from an exacerbation of COPD, that is severe enough to need hospitalisation, can be beneficial for these participants. It is anticipated that it may reduce the risk of being readmitted to the hospital or having a repeat exacerbation in the year following hospital discharge, and improve patients’ breathlessness, ability to perform physical activities and quality of life. We will compare the effects of using nasal high-flow in addition to usual care (with inhaled medications, steroids and sometimes antibiotics), to usual care alone.

The study aims to reduce the chance of participants having another exacerbation of COPD and needing to be readmitted to the hospital, following admission to the hospital. The investigators are comparing the effects of using home humidified high-flow therapy in addition to usual the normal care for COPD (which typically involves inhalers and a course of steroids and antibiotics) to usual care alone. Participants will be monitored during their hospital admission and for twelve months after they are discharged home as part of the study.

Who can participate?
Participants will be invited to participate if they have been admitted to the hospital with an exacerbation of COPD and the investigators feel that they are most likely to benefit from using this device.

What does the study involve?
This study will take place from participants' local hospital admission after they have completed the consent process and before they are discharged from the hospital and will continue for 12 months after discharge. The study team will collect data routinely taken as part of their normal care, including age, height, weight, medical history, medications list and results of vital signs (heart rate, blood pressure, breathing rate and oxygen levels), chest x-ray and blood test already taken by the medical team looking after you. We do not need to take any extra blood tests for the study but there are some optional elements that request blood tests be performed at some sites; this is optional and participants will only do it if they want to and not taking part will not impact participants taking part in the rest of the study.

What are the possible benefits and risks of participating?
Early studies have shown that high-flow therapy may benefit certain COPD patients who have not had a recent exacerbation. Based on these studies, we think it is possible that using high-flow therapy may reduce the risk of being readmitted to the hospital or having a repeat exacerbation and improve your breathlessness and quality of life. Taking part in the study will help us confirm whether this therapy is beneficial to patients with COPD who have had a recent exacerbation. However, we do not know whether this will happen, which is the main purpose of this study. All patients taking part in the study will benefit from regular visits from the research team who are experienced in supporting patients with COPD.
We do not expect any disadvantages from taking part. There are no major reported side effects of using high-flow therapy and studies have found that patients find it comfortable to use. If patients do experience any side effects from the device, they will be asked to contact their local site. All patients receive current “best practice” therapy. All the tests involve little/no discomfort, other than the time taken to perform them. The physical activity monitor can rarely cause mild and temporary irritation. The blowing and walking tests may feel uncomfortable as they require some effort but are safe. Arterial blood gas testing, which can cause mild to moderate discomfort, is an optional part of the study. This study will require time and commitment from the patients enrolled, which the research team appreciate and are very grateful for. All participants will be closely followed up by the research team who are experienced in the management of patients with COPD. We are keen that there are no risks involved in taking part. The study will be under the guidance of a Trial Steering Committee whose job is to ensure that the trial is managed well and to monitor safety.

Scientific titleExacerbation prevention in COPD - effect of home high-flow therapy versus usual care on hospital readmission or death after an acute chronic obstructive pulmonary disease (COPD) exacerbation: a UK-based multicentre randomised clinical trial
Study acronymEPiC-HFT
Study hypothesisThe use of home High Flow Humidified Therapy will prolong time to readmission or death following an admission to hospital with an exacerbation of COPD
Ethics approval(s)Approved 24/04/2023, South East Scotland Research Ethics Committee 1 (2ndFloor, Waverley Gate, 2-4 Waterloo Place, Edinburgh, EH1 3EG, UK; +44 (0)7814 764 241; Sandra.Wyllie@nhslothian.scot.nhs.uk), ref: 23/SS/0036
ConditionChronic obstructive pulmonary disease (COPD)
InterventionParticipants will be randomised into two parallel arms. To minimise imbalance and allow for known prognostic factors for future exacerbations, randomisation with stratification will be implemented, using the stratification factors of long-term oxygen use prior to enrolment, sex at birth, age (65 years) and BMI (=/25 kg/m²).

Participants will be randomised to the intervention or control arm. If randomised to the intervention arm participants will subsequently then be issued with an HFT device - high flow heated humidified device system. Patients randomised to the intervention will receive standard of care plus home high-flow therapy via the LUMIS-HFT device. They will be expected to use the device for approximately 8 hours per 24-hour period where possible for 12 months. The HFT will be titrated at all sites via a standardised protocol. Those in the control arm will continue to receive standard of care as per their local site, which is a best practice based on current BTS guidelines.
