Abstract

Surgeon experience certainly improves their technical efficiency although it also causes physiological changes with aging. The authors hypothesized that surgeons’ technical efficiency improves with increasing experience up to a point where it then decreases, which is a concave relationship. The authors collected data from all the surgical procedures performed at University Hospital from April through September in 2013–19. The dependent variable was defined as surgeons’ technical efficiency scores that were calculated using output-oriented Charnes–Cooper–Rhodes model of data envelopment analysis. Inputs were defined as (1) the number of assistants and (2) the duration of surgical operation. The output was defined as the surgical fee for each surgery. Surgeon experience was defined as the number of years since medical school graduation. Five control variables were selected: surgical volume, gender, academic rank, surgical specialty, and the year of surgery. Multiple regression analysis using pooled and random-effects Tobit models was performed for our panel data. Totally 20,375 surgical procedures performed by 264 surgeons in 42 months were analyzed. The coefficients of experience and the square of experience were not significantly different from zero. The other coefficients were also insignificant. Surgeons’ technical efficiency does not have a concave relationship with experience.

外科医生经验对技术效率的影响。

外科医生的经验当然会提高他们的技术效率，尽管它也会引起生理上的变化。作者假设，外科医生的技术效率随着经验的增加而提高，直到一定程度，然后下降，这是一个凹关系。作者收集了2013-19年4月至9月在大学医院进行的所有外科手术的数据。因变量定义为外科医生的技术效率评分，使用数据包络分析的输出导向Charnes-Cooper-Rhodes模型计算。输入定义为(1)助理人数和(2)手术时间。输出定义为每次手术的手术费用。外科医生经验定义为医学院毕业后的年数。选择5个控制变量:手术量、性别、学术等级、手术专业和手术年份。对我们的面板数据使用合并和随机效应Tobit模型进行多元回归分析。对264位外科医生在42个月内进行的20375例手术进行了分析。经验系数和经验平方均与零无显著差异。其他系数也不显著。外科医生的技术效率与经验并不成凹形关系。

期刊介绍： Health Services Management Research (HSMR) is an authoritative international peer-reviewed journal which publishes theoretically and empirically rigorous research on questions of enduring interest to health-care organizations and systems throughout the world. Examining the real issues confronting health services management, it provides an independent view and cutting edge evidence-based research to guide policy-making and management decision-making. HSMR aims to be a forum serving an international community of academics and researchers on the one hand and healthcare managers, executives, policymakers and clinicians and all health professionals on the other. HSMR wants to make a substantial contribution to both research and managerial practice, with particular emphasis placed on publishing studies which offer actionable findings and on promoting knowledge mobilisation toward theoretical advances.
