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

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.
