Impact of sleep hygiene on patients with obstructive sleep apnoea syndrome

Abstract

The purpose of this study was to evaluate the impact of a Sleep Hygiene brochure on a population of 36 patients recently diagnosed with Obstructive Sleep Apnoea Syndrome and beginning treatment. One expects that: 1) the information about Sleep Hygiene offered in the brochure would change some of the patients' habits toward sleep; and that, 2) this intervention in the form of a free informative brochure would have an echo in terms of a better subjective evaluation of sleep complaints. The sleep habits and the sleep complaints were evaluated in the pre-test. Those variables were re-evaluated in the post-test and at that time the patients filled in a scale of satisfaction with the information about Sleep Hygiene, in terms of its contribution to improving their sleep complaints. There were no significant differences in the level of compliance to Sleep Hygiene between the two periods, although the majority of the patients considered that Sleep Hygiene did improve their sleep difficulties. The low level of compliance may be due to the fact that patients already had reasonable Sleep Hygiene habits, and also to the fact that the scale was not sufficiently discriminative. In addition, the self-discipline that Sleep Hygiene involves may have collided with other demands such as the adaptation to treatment with CPAP (Continuous Positive Air Pressure). In a following study, it would be interesting to find if the levels of sleep hygiene compliance would change if they were implemented after the initial adaptation to CPAP, which would imply a longitudinal study. It would be helpful to keep reminding the patients of Sleep Hygiene importance, offering new and update brochures to the patients during consultations.
