The purpose of this study is to assess how the Hirsch Index (h-index) and other academic metrics change over time for academic minimally invasive surgeons (MIS).
Through the Fellowship Council's website, MIS program-directors and associate program-directors were identified in 2017 and again in 2018. Using the Scopus database, the number of publications, citations, self-citations, and h-indices were calculated.
A total of 222 surgeons were included. The median increase of publications, citations, and h-index were 4, 134, and 1, respectively. 75% of surgeons (166/222) saw their h-index increase. In 2017, 26% of surgeons (57/222) had an increase of their h-index due to self-citation. One-year later, 35% of those surgeons (20/57) no longer demonstrated that change.
Self-citation remains infrequent within MIS. The h-index of most surgeons will increase over one-year. Many surgeons demonstrating an increase in h-index due to self-citation will see that change eliminated over time.
本研究旨在评估学术微创外科医生（MIS）的 Hirsch 指数（h-index）和其他学术指标随时间的变化情况。
通过研究员理事会的网站，在 2017 年和 2018 年分别确定了 MIS 项目主任和副主任。使用 Scopus 数据库，计算了出版物数量、引用数量、自引数量和 h 指数。
共纳入 222 名外科医生。出版物、引用和 h 指数的中位数分别增加了 4、134 和 1。75%的外科医生（166/222）的 h 指数增加。2017 年，26%的外科医生（57/222）因自引而 h 指数增加。一年后，其中 35%的外科医生（20/57）不再显示这种变化。
MIS 中的自引仍然很少见。大多数外科医生的 h 指数将在一年内增加。许多因自引而 h 指数增加的外科医生将看到这种变化随着时间的推移而消除。
