These are peer-reviewed supplementary materials for the article 'Postoperative outcomes and anesthesia type in total knee arthroplasty in patients with obstructive sleep apnea' published in the Journal of Comparative Effectiveness Research.

Supplementary Table 1: Definition of International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes for general postoperative complications.
Supplementary Table 2: Definition of International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes for general postoperative complications.

Aim: 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. Materials & methods: 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). Results: 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. Conclusion: OSA was associated with increased 30/90-day readmission rates. Within NY, anesthetic type was not associated with any outcomes.
