[HTML][HTML] 5-years APAP adherence in OSA patients–do first impressions matter?
Respiratory medicine, 2013•Elsevier
Background Although continuous positive airway pressure (CPAP) is effective in treating
obstructive sleep apnoea (OSA), inadequate adherence remains a major cause of treatment
failure. This study aimed to determine long term adherence to auto adjusting-CPAP (APAP)
and its influencing factors including the role of initial compliance. Methods Eighty-eight male
patients with newly diagnosed moderate/severe OSA were included. After initiation of APAP
treatment, patients had periodic follow-up appointments at 2 weeks, 6 months and then …

Background
Although continuous positive airway pressure (CPAP) is effective in treating obstructive sleep apnoea (OSA), inadequate adherence remains a major cause of treatment failure. This study aimed to determine long term adherence to auto adjusting-CPAP (APAP) and its influencing factors including the role of initial compliance.
Methods
Eighty-eight male patients with newly diagnosed moderate/severe OSA were included. After initiation of APAP treatment, patients had periodic follow-up appointments at 2 weeks, 6 months and then annually for at least 5 years. Patient's compliance to therapy was assessed in each appointment and predictors to treatment abandonment and poor compliance were evaluated.
Results
The studied population had a mean age of 53.8 years and mean apnoea–hypopnoea index of 52.71/h.
The mean time of follow-up was 5.2 (±1.6) years, during that time 22 (25%) patients abandoned APAP, those who maintained treatment had good compliance to it since 94% of them used it more than 4 h/day for at least 70% of days.
A significant negative association was found between age, % of days and mean time of APAP use on 12th day and 6th month and the risk of abandoning. APAP use lower than 33% and 57% of days at 12th day and 6th month, respectively had high specificity (∼100%) to detect treatment abandonment.
Conclusions
the majority of patients adheres to long term APAP treatment and has good compliance after 5-years of follow-up. Age and initial compliance (% days of use and mean hour/day) have the ability to predict future adherence, as soon as 12 days and 6 months after initiation.
