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.

本数据集为发表于《比较疗效研究杂志》的论文《 obstructive sleep apnea 患者在全膝关节置换术后术后结果与麻醉类型》的同行评审补充材料。补充表1：国际疾病分类第九版临床修订版（ICD-9-CM）代码对一般术后并发症的定义。补充表2：国际疾病分类第十版临床修订版（ICD-10-CM）代码对一般术后并发症的定义。研究目的：本研究旨在探讨阻塞性睡眠呼吸暂停（OSA）、30/90天再入院率与围术期并发症（术后心血管、胃肠道、感染或术中并发症）在全膝关节置换术患者中的关系。研究材料与方法：我们分析了使用州住院数据库进行全膝关节置换术患者的记录。通过OSA状态对比了患者的人口统计学、合并症、30/90天再入院率和并发症。对于纽约州，我们按麻醉类型（区域麻醉与全身麻醉）分析了结果。研究结果：OSA患者以男性为主，合并症较多，且30/90天再入院率较高。并发症方面没有差异。在纽约州，麻醉类型与结果无差异。研究结论：OSA与30/90天再入院率增加相关。在纽约州，麻醉类型与任何结果均无关联。
