We have been serving a sleep health promotion in a local public transportation company. One of the projects is OSA screening for all commercial bus drivers. In addition, since April 2018, we have made provision for the CPAP adherence, that is, all of the bus drivers have been monitored adherence, and if CPAP adherence was poor for two consecutive times, an interview with us is mandated. In case of the drivers whose adherence is not improved after the interview, they must be away from driving until CPAP adherence is improved. Thus, we hypothesized such a provision makes CPAP adherence better as compared with real-world data of CPAP adherence in Japan (45.6%) which was our presentation at the SLEEP 2022. Pulse oximetry-based OSA screening is performed for all of the commercial bus drivers in the public transportation company. In case of 3% oxygen desaturation index ≥15, In-lab diagnostic PSG is performed. The drivers who are prescribed CPAP must submit CPAP adherence data sheet basically every month. Using the data of current employed bus drivers, we calculated the prevalence of OSA and recent CPAP adherence for a total of more than 90 days. CPAP adherence was defined as CMS criteria. The total number of commercial bus drivers in the company was 1237, of which 131 were diagnosed with OSA, 123 were CPAP users. The prevalence of OSA was 10.6%. Among 123 of CPAP users, 7 drivers lost the CPAP adherence data sheet, 1 driver was absent for a long time due to a malignant disease, and 2 drivers have recently started CPAP therapy, so CPAP adherence for 90 days could not be obtained, Eventually, CPAP adherence was assessed with 113 CPAP users. Eighty-seven drivers achieved CMS criteria, thus CPAP adherence was 77.0% which is comparable to the recent cloud-based CPAP adherence data in the US (72.6%). CPAP adherence in this study was higher than in the real-world data in Japan. Our sleep health promotion of CPAP therapy in this company successfully increased CPAP adherence.
