Positive airway pressure treatment for sleep-disordered breathing is rare during the first year after stroke: The BASIC project

Abstract

Objective/BackgroundSleep-disordered breathing (SDB) is very common after ischemic stroke, and its treatment may have a positive impact on recovery from stroke and on secondary stroke prevention. This study sought to determine the prevalence of positive airway pressure (PAP) use after stroke. Patients/methodsParticipants in the Brain Attack Surveillance in Corpus Christi (BASIC) project underwent a home sleep apnea test shortly after ischemic stroke. Demographics and co-morbidities were ascertained from the medical record. Self-reported PAP use (present vs absent) was assessed at 3, 6, and 12 months after stroke. Fisher exact tests and t-tests were used to compare PAP users versus non-users. ResultsOf 328 participants who were found to have SDB after stroke, only 20 (6.1%) indicated using PAP at any point during the 12-month follow up period. High pre-stroke sleep apnea risk based on Berlin Questionnaire score, neck circumference, and co-morbid atrial fibrillation were associated with any self-reported PAP use; race/ethnicity, insurance status and other demographic variables were not associated with PAP use. ConclusionsOnly a small proportion of individuals with ischemic stroke and SDB received treatment with PAP during the initial year after stroke among participants in this population-based cohort study in Nueces County, Texas. Closing the substantial treatment gap for SDB after stroke might improve sleepiness and neurologic recovery.
