Abstract
We examined the relation between surgical volume and mortality, within 60 days of surgery, for eight procedures on aged Medicare beneficiaries. Logistic regression revealed that high surgical volume was significantly associated with lower mortality for resection of the intestine, coronary artery bypass, transurethral resection of the prostate (TURP), and hip arthroplasty (excluding total hip replacement). For cholecystectomy, total hip replacement, inguinal hernia repair, and femur fracture reduction, no relationship was found between surgical volume and postsurgical mortality. The analyses were repeated using inhospital deaths as the dependent variable, and the results indicated a considerably stronger association between volume and mortality.
摘要
我们研究了老年医疗保险受益人的八项手术在术后60天内手术量与死亡率之间的关系。逻辑回归显示，对于肠道切除术、冠状动脉搭桥术、经尿道前列腺切除术（TURP）和髋关节置换术（不包括全髋关节置换术），高手术量与较低死亡率显著相关。对于胆囊切除术、全髋关节置换术、腹股沟疝修补术和股骨骨折复位术，未发现手术量与术后死亡率之间存在关联。使用住院死亡作为因变量重复进行分析，结果表明手术量与死亡率之间的关联更强。
