Clinical Trial Summary

Domiciliary non-invasive ventilation (NIV) is a standard care for improving survival rates of selected patients with chronic hypercapnic respiratory failure (CHRF) and to improve the patients' hypercapnia, sleep quality, health-related quality of life (QoL). Adherence is an important factor affecting clinical effectiveness of domiciliary NIV. Our previous study has noted the associations between poor domiciliary NIV adherence and increased number of clinical adverse events (p = 0.004) and increased hospitalization requiring acute NIV salvage (p = 0.042). However, there are very limited studies on adherence to domiciliary NIV in patients with CHRF. The only interventional study was a single-group pre-test post-test study and lack of a theoretical framework for guiding the intervention. This study is employing an Information-Motivation-Behavioral skills (IMB) model-based intervention to improve inhalation adherence in a group of chronic obstructive pulmonary disease (COPD) patients.

Clinical Trial Description

The study design is a multi-center, 2-arm single-blind randomized controlled trial. The intervention group will receive an Information-Motivation-Behavioral (IMB) model-based intervention while the control group will receive the usual care.

Usual Care: There is a respiratory team of health care professionals responsible for patients requiring domiciliary non-invasive ventilation (NIV). The team is led by a Medical Consultant and with respiratory nurse(s) as team members who are responsible for assisting patients or their family to initiate domiciliary NIV and teaching the relevant technical skills. The nurse will provide an one-hour face-to-face session to introduce the choices of domiciliary NIV and teach the patient or his/her family on how to operate and maintain the ventilator, interface and accessories, and also how to handle the common problems such as leakage and pressure sore in hospital before discharge. Commercial leaflet or booklet according to the choice of ventilator with information of the ventilator, interface, accessories and the ventilator company will be provided to the patient.

Intervention:

There will be a respiratory team, same as the usual care, responsible for patients requiring domiciliary NIV in the intervention group. The IMB model-based intervention of this study is a six-week program consisted of a one-hour face-to-face home visit in the first week, two 20-minute telephone follow-ups in the second and fourth weeks, and a half-hour face-to-face follow-up at hospital in the sixth week, and a telephone consultation hotline during office hours. ;
