Based on strategic human capital theory, this study examines the effects of star surgeons on two different types of healthcare outcomes (i.e., number of surgical patients and length of patients’ in-hospital stay after surgery) in the surgery department. We also explore whether the relationship between star surgeons and healthcare outcomes is contingent on the expertise disparity between star and non-star surgeons. The results of an empirical analysis on colorectal cancer surgeons in 80 departments in South Korean hospitals show that the number of star surgeons increases the number of surgical patients and reduces the length of patients' stay after surgery. Moreover, the positive relationship between star surgeons and the number of surgical patients is strengthened when the expertise disparity between star and non-star surgeons is low. The implications of these findings for research and practice are also discussed.

明星员工是帮助还是阻碍部门绩效：以韩国医院外科医生为例

基于战略人力资本理论，本研究考察了明星外科医生对外科手术部门两种不同类型的医疗保健结果（即手术患者人数和患者术后住院时间）的影响。我们还探讨了明星外科医生与医疗保健结果之间的关系是否取决于明星和非明星外科医生之间的专业差异。对韩国医院80个科室结直肠癌外科医生的实证分析结果表明，明星外科医生的数量增加了手术患者的数量，减少了患者术后住院时间。此外，当明星外科医生与非明星外科医生之间的专业差异较小时，明星外科医生与手术患者数量之间的正相关关系得到加强。
