Supplementary tables: Postoperative outcomes and anesthesia type in total knee arthroplasty in patients with obstructive sleep apnea

<b>These are peer-reviewed supplementary materials for the article '</b><b>Postoperative outcomes and anesthesia </b><b>type in total knee arthroplasty in patients </b><b>with obstructive sleep apnea</b><b>' published in the</b><b> </b><b><i>Journal of Comparative Effectiveness Research</i></b><b>.</b><b>Supplementary Table 1: </b>Definition of <i>International Classification of Diseases, Ninth Revision, Clinical Modification</i> (ICD-9-CM) codes for general postoperative complications.<b>Supplementary Table 2: </b>Definition of <i>International Classification of Diseases, Tenth Revision, Clinical Modification</i> (ICD-10-CM) codes for general postoperative complications.<b>Aim:</b> We investigated the relationship between obstructive sleep apnea (OSA), 30/90-day readmission rates and perioperative complications (postoperative cardiovascular, gastrointestinal, infectious or intraoperative complications) in patients undergoing total knee arthroplasty. <b>Materials &amp; methods:</b> We analyzed records of patients who underwent total knee arthroplasty using State Inpatient Databases. Demographics, comorbidities, 30/90-day readmission rates and complications were compared by OSA status. For NY, USA we analyzed outcomes by anesthetic type (regional vs general). <b>Results:</b> OSA patients were mostly male, had more comorbidities and had increased 30/90-day readmission rates. There were no differences in complications. In NY, there were no differences in outcomes by anesthetic type. <b>Conclusion: </b>OSA was associated with increased 30/90-day readmission rates. Within NY, anesthetic type was not associated with any outcomes.
