Abstract T P263: Screening Practices for Sleep-Disordered Breathing in Stroke Medical Community

Background: Frequency of sleep-disordered breathing (SDB) among stroke and TIA patients ranges from 50% to 94%, and is associated with poor neurological outcomes. Per current stroke prevention guidelines from American Stroke Association, SDB is included in the list of modifiable risk factors for stroke and TIA prevention. The goal of our study was to determine screening practices for SDB in stroke medical community. Methods: A web-based survey was conducted between 12/2013 to 7/2014 among practitioners taking care of stroke patients across United States and Europe. Results: Among 112 total responses (18%), 91 were stroke physicians (81.25%), 9 were general neurologist (8.04%), 3 were sleep medicine physicians (2.68%) and 9 were other specialty (8.04%). Majority of practitioners (72%, n= 81) do not use SDB screening questionnaires in their stroke patients. Epworth sleepiness scale is the most used among SDB questionnaires (24%), followed by Berlin sleep questionnaire (9.5%) and STOP-BANG questionnaire (7%). Only 12% of practitioners use screening questionnaires in both in-patients and out- patients, where as 20% use only in out- patients and 5% use only in acute stroke setting. Only 50% of practitioners would refer their stroke patients to a sleep medicine specialist when patients were screened positive for SDB on questionnaires. Conclusion: Despite being an independent risk factor for stroke and TIA, majority of practitioners do not screen stroke and TIA patients for SDB. Further work is needed to improve screening practices for SDB in stroke medical community.
