P108 Improving continuous positive airway pressure trial compliance in obstructive sleep apnea patients

Abstract Background Obstructive sleep apnea (OSA) is highly prevalent in Singapore (20-30%). Patients are enrolled into a CPAP trial after the diagnosis of OSA where they are provided with a CPAP machine for one month. However, CPAP compliance and uptake rates during and after the CPAP trial are often low as it is not well tolerated. As untreated OSA results in persistent daytime sleepiness and major adverse cardiac events in the long term, our aim is to improve CPAP trial compliance in OSA patients, which in turn improves long-term CPAP compliance and uptake rates. Method Our team identified factors that led to low CPAP compliance and developed a new practice of contacting patients via phone during their 1st week of CPAP trial to troubleshoot CPAP issues. Results Data analysis of CPAP trials was conducted pre- (Year 2020) and post-implementation (Year 2021) of this new practice of follow up calls during the 1st week of CPAP trial. We sampled 30 patients from Year 2020 and 2021 respectively to analyse their CPAP compliance and long-term uptake rates after completion of CPAP trial. Outcomes achieved are 1. Increased CPAP compliance (overall % of days with >4hours CPAP use) during CPAP trial. 2. Increased long-term CPAP uptake after completion of CPAP trial (46.7% in 2020 vs 86.7% in 2021). 3. Improved patient satisfaction Discussion Addressing CPAP issues early on during the CPAP trial significantly improved long-term CPAP compliance and uptake rates, which will improve quality of life and long-term cardiovascular health.
