By utilizing the large Veterans Health Administration (VHA) national administrative databases, we sought to determine the incidence, clinical correlates, and impact of CSA on healthcare utilization in Veterans. Analysis of a retrospective cohort of patients with sleep disorders was performed from outpatient visits and inpatient admissions from fiscal years 2006 through 2012. The CSA group, defined by International Classification of Diseases-9, was compared with a comparison group. The number of newly diagnosed CSA cases increased fivefold during this timeframe; however, the prevalence was highly variable depending on the VHA site. The important predictors of CSA were male gender (odds ratio [OR] = 2.31, 95% confidence interval [CI]: 1.94\u20132.76, p &amp;lt; 0.0001), heart failure (HF) (OR = 1.78, 95% CI: 1.64\u20131.92, p &amp;lt; 0.0001), atrial fibrillation (OR = 1.83, 95% CI: 1.69\u20132.00, p &amp;lt; 0.0001), pulmonary hypertension (OR = 1.38, 95% CI:1.19\u20131.59, p &amp;lt; 0.0001), stroke (OR = 1.65, 95% CI: 1.50\u20131.82, p &amp;lt; 0.0001), and chronic prescription opioid use (OR = 1.99, 95% CI: 1.87\u20132.13, p &amp;lt; 0.0001). Veterans with CSA were at an increased risk for hospital admissions related to cardiovascular disorders compared with the comparison group (incidence rate ratio [IRR] = 1.50, 95% CI: 1.16\u20131.95, p = 0.002). Additionally, the effect of prior HF on future admissions was greater in the CSA group (IRR: 4.78, 95% CI: 3.87\u20135.91, p &amp;lt; 0.0001) compared with the comparison group (IRR = 3.32, 95% CI: 3.18\u20133.47, p &amp;lt; 0.0001). Thus, CSA in veterans is associated with cardiovascular disorders, chronic prescription opioid use, and increased admissions related to the comorbid cardiovascular disorders. Furthermore, there is a need for standardization of diagnostics methods across the VHA to accurately diagnose CSA in high-risk populations.<\/jats:p>","DOI":"10.1093\/sleep\/zsy058","type":"journal-article","created":{"date-parts":[[2018,3,28]],"date-time":"2018-03-28T06:43:19Z","timestamp":1522219399000},"source":"Crossref","is-referenced-by-count":31,"title":["Correlates and consequences of central sleep apnea in a national sample of US veterans"],"prefix":"10.1093","volume":"41","author":[{"given":"David","family":"Ratz","sequence":"first","affiliation":[{"name":"Center for Clinical Management Research, VA Ann Arbor Healthcare System, Ann Arbor, MI"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wyndy","family":"Wiitala","sequence":"first","affiliation":[{"name":"Center for Clinical Management Research, VA Ann Arbor Healthcare System, Ann Arbor, MI"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M Safwan","family":"Badr","sequence":"first","affiliation":[{"name":"Sleep Medicine Section, Medical Service, John D.
