Six early CPAP-usage behavioural patterns determine peak CPAP adherence and permit tailored intervention, in patients with obstructive sleep apnoea.

Background: High rates of non-adherence to continuous positive airway pressure (CPAP) in obstructive sleep apnoea hamper good clinical outcomes. Current recommendations assumes two behaviours (adherence and non-adherence) and days 7-90 follow-up post-CPAP initiation mitigates against non-adherence.

Objectives: To investigate associations between early CPAP-usage behaviours and (1) CPAP adherence at month 3 of treatment and (2) sleep centres' treatment pathways (the procedures patients undergo that may affect barriers or facilitators of CPAP adherence).
