Following publication of the home oxygen therapy-home mechanical ventilation (HOT-HMV) trial, the purpose of this study is to evaluate the clinical service delivery of home non-invasive ventilation (NIV) therapy in patients who have recently undergone, and recovered, from a life-threatening exacerbation of COPD. This prospective cohort observational study is designed to evaluate the clinical implementation of the delivery of home non-invasive ventilation in COPD patients with persistent hypercapnia following an acute exacerbation of COPD to validate that the clinical benefit demonstrated by the HOT-HMV trial is maintained when the home non-invasive ventilation is incorporated into routine clinical practice. Patients who have an admission to hospital with an acute exacerbation of COPD requiring non-invasive ventilation will be referred for assessment. Eligible patients will be referred by the critical care or appropriate respiratory team to a monthly assessment clinic for assessment of chronic hypercapnia. The total UK sample size will be 200 participants. St Thomas' critical care unit managed between 80-100 patients per year with non-invasive ventilation for life threatening exacerbation of COPD. This study will run over 4 years; therefore it is anticipated that 200 patients will be enrolled into the trial over this period. Patients will also be referred from peripheral hospitals to the Lane Fox Unit as a regional centre for home ventilation.
