ABSTRACT
Introduction: Due to the COVID-19 pandemic, there may be changes in continuous positive airway pressure (CPAP) adherence. This study aimed to examine the longitudinal effect of using CPAP as advised and self-reported sleep quality improvements in sleep medicine clinic patients using CPAP early in the pandemic and six months later. Methods: Between June-November 2020, 81 sleep medicine clinic patients completed an online survey that included questions about CPAP use, using CPAP as advised, and changes in sleep quality associated with CPAP use. Patients were recontacted 6 months later to complete the same survey. Among survey respondents completing both surveys, 27 (50%;aged 58±18.2 y, 48% female, 67% Caucasian) reported using CPAP and were included in the present analysis. We conducted multivariate regression analyses Chisquare Association tests to determine whether self-reported CPAP use, CPAP use as advised, and sleep quality changed from baseline to 6-month follow up during the pandemic. Results: Among CPAP users, 89% reported no change, 7% reported they use CPAP more, and 4% reported they use CPAP less at 6-month follow up. There was a significant increase in using CPAP as advised at 6-month follow up compared to the baseline survey, p=0.003. Additionally, there was a significant improvement self-reported sleep quality while using CPAP at 6-month follow up compared to the baseline survey, p=0.012. Conclusion: Patients reported an increase in using CPAP advised and improvements in sleep quality as a result of CPAP use at 6-month follow up compared to a baseline survey administered early in the pandemic. Understanding why patients are more adherent to using CPAP as advised during the pandemic may help in developing interventions to increase CPAP adherence.
