Educational video demonstrating collapsibility of the upper airway during sleep improves initial acceptance of CPAP in patients with severe obstructive sleep apnea: a retrospective study.

Study Objectives: We investigated whether an audiovisual educational video demonstrating collapsibility of the upper airway during sleep would influence initial continuous positive airway pressure (CPAP) acceptance among patients with severe obstructive sleep apnea.
Methods: Between January 2017 and December 2018, a single-center retrospective study was conducted. We implemented an educational video demonstrating upper airway collapsibility during sleep in February 2018. We analyzed the medical records from 145 consecutive patients diagnosed with severe obstructive sleep apnea who underwent in-laboratory polysomnography both before and after implementing the educational video. Among them, 76 patients received standard care before the video's introduction (standard care group), and another 69 patients were managed after its implementation (video group).
Results: Baseline characteristics including age, body mass index, educational level, occupation category, comorbidities, Mallampati score, Epworth Sleepiness Scale score, apnea-hypopnea index, and sleep time with SpO ₂ below 90% were not significantly different between the 2 groups. Acceptance of CPAP following an in-laboratory overnight titration study was significantly higher in the video group (80%) than in the standard care group (57%) ( P = .003). Multivariate regression analyses revealed that watching the video was a strong predictor of initial CPAP acceptance (odds ratio, 4.162; 95% confidence interval, 1.627-10.646; P = .004). Both sleep time with SpO ₂ below 90% (odds ratio, 1.020; 95% confidence interval, 1.002-1.038; P = .029) and sleep efficiency (odds ratio, 1.052; 95% confidence interval, 1.023-1.083; P < .001) were weak predictors for initial CPAP acceptance. At 12 months, adherence among those who accepted the CPAP treatment was similar between the 2 groups (78% vs 74%; P = .662). However, within the initial cohorts, a significantly higher proportion of patients in the video group (62%) were using CPAP at 12 months compared with the standard care group (42%) ( P = .015).
Conclusions: Among patients with severe obstructive sleep apnea, an educational video demonstrating upper airway collapsibility during sleep improved initial CPAP acceptance rates when compared with standard care.
