Effect of information - motivation - behavior skills on adherence of continuous positive airway pressure therapy in patients with obstructive sleep apnea hypopnea syndrome

Obstructive sleep apnea hypopnea syndrome (OSAHS) is a common disease that seriously affects health. Continuous positive airway pressure (CPAP) therapy is the preferred treatment for moderate-to-severe OSAHS patients. However, poor adherence to CPAP is a major obstacle in the treatment of OSAHS. Information-motivation-behavioral (IMB) skills, as a kind of mature technology to change the behavior, has been used in various health areas to improve treatment adherence. This study aims to explore the effects of the IMB skills intervention on CPAP adherence in OSAHS patients. Patients who were primary diagnosed with moderate-to-severe OSAHS were randomly divided into the IMB group ( =62) and the control group ( =58). The patients in the IMB group received CPAP therapy and the IMB skills intervention for 4 weeks. The patients in the control group received CPAP therapy and a usual health care provided by a registered nurse. We collected the baseline data of the general information, including age, sex, body mass index (BMI), the Epworth Sleepiness Scale (ESS) score, the Hospital Anxiety and Depression Scale (HADS) score, and indicators about disease severity [apnea-hypopnea index (AHI), percentage of time with arterial oxygen saturation SaO 0.05). There were no significant differences in score of willingness to continue CPAP therapy, as well as score of satisfaction and acceptance of CPAP therapy after CPAP titration between the IMB group and the control group (both >0.05). After 4 weeks treatment, the ESS score, HADS score,
