Guidelines favor considering sleep testing among patients with cerebrovascular events.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n To evaluate the effectiveness of a quality improvement intervention to increase OSA diagnostic testing after stroke or TIA.<\/jats:p>\n <\/jats:sec>\n \n Design, Setting, and Participants<\/jats:title>\n This stepped-wedge cluster randomized trial of patients with ischemic stroke or TIA admitted to Department of Veterans Affairs facilities assessed outcomes during 8 data periods of 7-month duration (May 15, 2019, to January 24, 2024).<\/jats:p>\n <\/jats:sec>\n \n Intervention<\/jats:title>\n The quality improvement intervention was implemented with a virtual kickoff; site teams reviewed their facility\u2019s baseline data, identified improvement opportunities, considered barriers and potential solutions to diagnosing OSA among patients with cerebrovascular disease, and developed a site-specific action plan. Team members attended monthly collaborative conferences. A web-based platform provided quality data, action plans, and a resource library. The research team provided external facilitation.<\/jats:p>\n <\/jats:sec>\n \n Main Outcomes and Measures<\/jats:title>\n The primary outcome was 30-day OSA diagnostic testing rate. Secondary outcomes were 30-day positive airway pressure treatment rate, 90-day recurrent vascular event rate, and 90-day readmission rate. Implementation effects were assessed using generalized linear mixed-effects models with binomial distributions and log link fit to patient-level data with site-level random effects.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The study included 1747 patients at 6 intervention sites (mean [SD] age, 68.7 [11.1] years; 1634 [93.5%] male) and 7454 patients at 30 usual care sites (mean [SD] age, 71.8 [10.8] years; 7114 [95.4%] male). The index event was stroke (vs TIA) in 1429 (81.8%) at the intervention sites and 5931 (79.6%) at the usual care sites. The 30-day diagnostic testing rate increased from 2.1% (20 of 952) during baseline to 29.1% (189 of 650) during implementation (odds ratio [OR], 16.13; 95% CI, 8.25-31.53); the 30-day diagnostic testing rate varied from 0.7% to 2.2% among usual care sites across data periods. Thirty-day positive airway pressure treatment increased from 0.3% (3 of 952) during baseline to 2.8% (18 of 650) during implementation (OR, 14.22; 95% CI, 2.40-84.40) at the intervention sites, while varying from 0.0% (0 of 876) to 0.4% (4 of 1158) at the usual care sites. No statistically significant changes were observed in 90-day readmission or recurrent vascular event rates.<\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n In this cluster randomized trial of patients with acute cerebrovascular events, quality improvement approaches increased OSA testing. These results suggest that health care systems can improve the delivery of guideline-concordant care for patients with acute ischemic stroke and TIA by delivering inpatient sleep medicine services.<\/jats:p>\n <\/jats:sec>\n \n Trial Registration<\/jats:title>\n \n ClinicalTrials.gov Identifier:\n NCT04322162<\/jats:ext-link>\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1001\/jamanetworkopen.2025.43385","type":"journal-article","created":{"date-parts":[[2025,11,14]],"date-time":"2025-11-14T16:30:40Z","timestamp":1763137840000},"page":"e2543385","source":"Crossref","is-referenced-by-count":5,"title":["Quality Improvement Intervention to Increase Sleep Apnea Diagnostic Testing After Stroke and Transient Ischemic Attack"],"prefix":"10.1001","volume":"8","author":[{"given":"Dawn M.","family":"Bravata","sequence":"first","affiliation":[{"name":"Department of Veterans Affairs (VA) Health Services Research and Development (HSR&D) Expanding Expertise Through E-health Network Development Quality Enhancement Research Initiative, Indianapolis, Indiana"},{"name":"VA HSR&D Center for Health Information and Communication, Richard L.
