Intervention
Control - usual care
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. There are three major components including information, motivation and behavioral skill interventions as proposed by the IMB model and will be deliberately arranged in the different sessions.
There is a respiratory team of health care professionals responsible for patients requiring domiciliary 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.
