[A cross-sectional survey of treatment acceptance and influence factors in patients with obstructive sleep apnea].

Objective To investigate the treatment acceptance in patients with obstructive sleep apnea (OSA) and its influence factors. Methods This cross-sectional survey recruited OSA patients diagnosed at sleep center in Guangdong General Hospital from January 2014 to December 2015. By phone follow-up, a pre-designed questionnaire was performed for all adults, which composed of the following sections: treatment or none, treatment method, reason for non-treatment, revisit or none. Results From 524 OSA patients with completed contact information, 480 (91.6%) valid questionnaires were collected. The apnea hypopnea index was (36.1±21.4) /h. The mild, moderate, severe OSA patients accounted for 12.5%(60 cases), 33.1%(159 cases), 54.4%(261 cases) respectively. For all 480 included subjects, 200 (41.7%) received treatment and among them 184 (92.0%) were treated by continuous positive airway pressure. The treatment rate was lower in mild OSA, non-obesity, female, and patients without daytime sleepiness. Receiving treatment was negative correlated to difficult falling asleep. The first reason of non-treatment was self-determined behavioral intervention and the second was self-concept of no requirement for treatment. The specialist revisit rate was 3.8%, which was slightly higher in treated patients and those with sudden awakening when feeling asphyxia. Conclusion A majority of OSA patients do not receive treatment, primarily as a result of their self-determined behavior intervention and self-concept of no requirement for treatment.
