Optimal compliance (as defined by NIV use for more than 6 hours/24 hours) varied according to underlying diagnosesView this table:Table1. Compliance was highest amongst patients with neuromuscular disease (100%) and lowest in those with COPD (48%). Suboptimal compliance was associated with higher mortality in all diagnoses but ORRF during the study periodDiscussion: Our data demonstrates that compliance with HNIV varies according to underlying diagnosis. For all diagnoses better compliance is associated with improved survival. The higher mortality despite optimal compliance in the ORRF group might be attributed to the complex co-morbidities usually associated with this condition. Future prospective studies are needed to examine this in detail and to identify factors associated with optimal compliance.
