Abstract:

INTRODUCTION: Obstructive sleep apnea syndrome (OSA) afflicts approximately 5% of the adult population and increases with age.

RESULTS: The number of regular users increased between the 1st and 2nd year from 126 (34%), to 163 (44%) (p < 0.07) due to additions from the intermittent users group. The non-users group grew from 120 (32.3%) in the first year, and every year afterwards, up to 221 (59.6%) in the fourth year (p < 0.02). In contrast, there was a significant decrease in the intermittent users group, which declined from 125 (33.7%) in the first year to only 18 (4.8%) in the 4th year (p < 0.005). Most of the patients (92.9%) were males. The average age of the regular users was 59.6 years (+/- 11), which was higher in comparison to 55.9 years (+/- 10.3) for the non-users or 58.9 years (+/- 12.6) among the intermittent users (p = 0.064). There were no statistical differences in co-morbidities or demographics between the three groups. However, the regular users were found to have a higher score in the Epworth Sleepiness Scale (ESS) and a minimal arterial oxygen saturation (SaO2) level lower than the patients in the non-users and intermittent users groups (p = 0.019 and p = 0.03 respectively).

CONCLUSIONS: Ongoing medical and social support is needed in order to maintain good compliance.
