0477 Impact of Socioeconomic Disparities on CPAP Compliance

Abstract Introduction Social disparities is known to have a significant impact on health outcomes including those related to obstructive sleep apnea (OSA). More recently a metric known as area deprivation index (ADI) which combines 17 social determinants of health has been used to better quantify this impact. We aim to examine the relationship between socioeconomic disparities and CPAP adherence among adults with OSA using ADI. Methods Retrospective chart review of patients with diagnosis of OSA and prescribed CPAP from Oct-Dec 2022. Patients were divided into more or less socioeconomically disadvantaged groups using a validated measure, the area deprivation index (ADI). 30 day CPAP compliance was collected. CPAP compliance was defined using Medicare criteria (4hrs/night 70% of the nights). Long term CPAP data is currently being collected. Results 452 patients included. Patients from the most deprived areas as determined by ADI had significantly lower CPAP compliance than those from the most advantaged areas (34% compared to 56%) (p 0.05). Patients from areas with lower rates of high school graduates had lower CPAP compliance (p 0.05). In multivariate regression non-English speaking appeared to be a significantly negative predictor of CPAP compliance. Conclusion Socioeconomic disparities appear to have a significant impact on CPAP compliance. In particular, those from areas that are considered more deprived, areas with lower rates of high school graduates and non English speakers seem to be impacted the most. Patients within these groups may benefit from additional resources and/or closer follow up to improve compliance with treatment. Support (if any)
