This study investigates the association between preoperative anemia and 30-day postoperative complications following aseptic revision total shoulder arthroplasty (TSA).
The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients who underwent aseptic revision TSA from 2015 to 2022. The study population was divided into two cohorts based on preoperative hematocrit (HCT): normal (Male HCT ≥ 41%; Female HCT ≥ 36%) and anemia (Male HCT < 41%; Female HCT < 36%). Logistic regression analysis was conducted to investigate the relationship between anemia and postoperative complications following aseptic revision TSA.
Anemia was independently associated with any complication (OR 1.71, 95% CI 1.40-2.10; P < 0.001), blood transfusions (OR 8.71, 95% CI 4.23-17.90; P < 0.001), non-home discharge (OR 1.81, 95% CI 1.26-2.60; P = 0.001), and length of stay exceeding 2 days (OR 1.81, 95% CI 1.43-2.29; P < 0.001).
Patients with anemia experienced significantly higher rates of early postoperative complications after aseptic revision TSA. These findings provide evidence for the use of preoperative HCT measurements as a practical predictor of postoperative risk in this setting.

本研究调查无菌性翻修全肩关节置换术（TSA）术前贫血与术后30天并发症之间的关联。
查询美国外科医师学会国家外科质量改进计划数据库中2015年至2022年接受无菌性翻修TSA的所有患者。根据术前血细胞比容（HCT）将研究人群分为两组：正常组（男性HCT≥41%；女性HCT≥36%）和贫血组（男性HCT<41%；女性HCT<36%）。进行逻辑回归分析以研究贫血与无菌性翻修TSA术后并发症之间的关系。
贫血与任何并发症（比值比[OR]1.71，95%置信区间[CI]1.40 - 2.10；P<0.001）、输血（OR 8.71，95% CI 4.23 - 17.90；P<0.001）、非回家出院（OR 1.81，95% CI 1.26 - 2.60；P = 0.001）以及住院时间超过2天（OR 1.81，95% CI 1.43 - 2.29；P<0.001）独立相关。
贫血患者在无菌性翻修TSA术后早期并发症发生率显著更高。这些发现为在这种情况下使用术前HCT测量作为术后风险的实用预测指标提供了证据。证据级别：三级；回顾性队列比较；预后研究。
