Rationale: Obstructive sleep apnea (OSA) is a common treatable condition with important health and societal consequences. Objectives: We aimed to assess the annual incidence and prevalence of clinically recognized and geographic clustering of OSA in Alberta, Canada, using administrative health data case definitions. Methods: We used two administrative health databases in Alberta to identify ICD-9 and ICD-10 (International Classification of Diseases, Ninth and 10th Revisions, respectively) diagnostic codes for adults and children at least 2 years old diagnosed with OSA between 2003 and 2020. We defined OSA using an algorithm developed and validated in Alberta: at least three claims or one hospitalization within 2 years. We mapped residential postal codes to 70 subregional health authorities (SRHAs). Crude, age group- and sex-specific incidence and prevalence, and age group- and sex-standardized rates were calculated for Alberta and SRHAs. Spatial scan statistics identified clusters of SRHAs in which OSA cases were higher (hot spots) or lower (cold spots) than expected. Results: Between 2003 and 2020, OSA prevalence increased from 0.14% to 4.59%. The annual incidence of OSA increased after 2013. Incidence and prevalence were higher in older adults and children aged 2-11 years compared with 12-17 years. Cluster analysis revealed regional variation in OSA incidence and prevalence over time with no consistent pattern except for cold spots in one large metropolitan center (Calgary). Conclusions: From 2003 to 2020, the incidence and prevalence of clinically recognized OSA increased but varied by geography. Administrative health data can be used to guide interventions aimed at improving health service delivery and the quality of OSA care. |
