  • Abstract [Aim] The definition of good adherence to continuous positive airway pressure (CPAP) therapy for obstructive sleep apnea syndrome (OSA) is a utilization rate of ≥70% and a mean usage time on usage days of ≥ 4 hours, and users who deviate from this definition are regarded as having poor adherence. Personalized guidance is required to improve the adherence of users with poor adherence. Hence, a more detailed classification is needed rather than simply classifying users as having poor and good adherence. Thus, this study aimed to clarify the significance of classification of adherence into four groups based on the two indices of utilization rate (%) and mean usage time (hours). [Method] This study examined CPAP users at the CPAP specialist outpatient department from October to November 2016. In total, 535 patients were included, and information on CPAP adherence, physical data at initial consultation, and data on motivation for consultation were collected. The survey period was set as 2 months. The CPAP users were divided into four groups, and a 4-group comparison was conducted on factors that affect adherence, using the χ ² test, the Kruskal-Wallis test, and the pairwise method. The utilization rate was set as the vertical axis and the mean usage time on usage days was set as the horizontal axis to create a scatter plot. The four segments were created by intersecting the axes with the values of “70%” and “4 hours”, with the top right set as the good adherence group “≥70%/≥ 4 hours”; moving counterclockwise, the next segments were set as the insufficient adherence time group “≥70%/<4 hours,” poor adherence group “≤70%/<4 hours,” and insufficient adherence days group “<70%, ≥ 4 hours.” [Results] The good adherence group (n=393) accounted for 70% of users; the remaining 30%, conventionally classified together as users with poor adherence, were distributed into insufficient adherence time group (n=31), poor adherence group (n=49), and insufficient adherence days group (n=62). No significant differences in sex or residual AHI were observed, but significant difference was observed in age, usage history, and BMI between the good adherence group and poor adherence group. The percentage of patients with hypertension was significantly different between the good adherence group and insufficient adherence days group. There was a significant difference in the percentage of patients who sought consultation due to subjective symptoms between the insufficient adherence days group and insufficient adherence time group. The percentage of patients who sought consultation due to a recommendation by a company medical checkup showed a significant difference between the good adherence group and insufficient adherence days group. [Conclusion] These results suggest that adherence can be divided into four groups based on utilization rate and mean usage time on usage days, and that these classifications may be helpful for constructing a guidance management system that emphasizes personalized guidance systems.
