外科医生的手术量可能是手术质量和成本结果的一种重要的预测因素。为了研究对于结肠癌患者外科医生手术量和手术护理的质量和成本之间的关系,Damle RN等对在2008~2011年期间17 749例实行了结肠切除术的患者进行了回顾性研究。其中,外科医生手术量根据相对于平均水平进行高中低分类。结果中发现,与低手术量相比,中高手术量医生更倾向于使用腹腔镜手术(高手术量:OR为1.27,95%CI为1.15~1.39;中手术量:OR为1.16,95%CI为1.65~1.26);高手术量 The amount of surgeon surgery may be an important predictor of the quality of the procedure and the cost result. To investigate the relationship between the surgeon’s surgical volume and the quality and cost of surgical care in patients with colon cancer, Damle RN et al. Conducted a retrospective review of 17 749 patients who underwent colectomies between 2008 and 2011. Among them, surgeons surgery based on the average level of high school low classification. The results showed that, compared with the low amount of surgery, physicians in high and middle operation more likely to use laparoscopic surgery (high surgery: OR 1.27,95% CI 1.15 ~ 1.39; the amount of surgery: OR was 1.16,95% CI 1.65 ~ 1.26); high volume of surgery
