Abstract

INTRODUCTION

The h-index is a widely utilized academic metric that measures both productivity and citation impact. The purpose of this study is to define the impact of self-citation among minimally invasive surgery (MIS) fellowship program directors.

METHODS

Through the Fellowship Council's website, all program directors and associate program directors from the 148 MIS fellowship programs were identified. Using the Scopus database, we calculated the number of publications, citations, self-citations, and h-index for each surgeon.

RESULTS

A total of 274 surgeons were identified. The mean number±SD of publications, citations, and h-index for the cohort were 60.5 ± 77.2, 1765 ± 4024, and 16.0 ± 15.0, respectively. The self-citation rate for the entire cohort was 3.23%. Excluding self-citations reduces the mean number of citations to 1708 ± 3887 and h-index to 15.8 ± 14.6. The h-index remained unchanged for 77% (210/274) of surgeons. Only 5% (15/274) of surgeons had a change in h-index of greater than one integer and no surgeon had a change greater than three integers.

CONCLUSION

Self-citation is infrequent and has a minimal impact on the academic profile of program directors of MIS fellowships.

摘要

简介

h 指数是一种广泛应用的学术指标，用于衡量生产力和引文影响力。本研究旨在定义微创外科（MIS）研究员计划主任的自我引用的影响。

方法

通过 Fellowship Council 的网站，确定了 148 个 MIS 研究员计划的所有主任和副主任。我们使用 Scopus 数据库计算了每位外科医生的出版物数量、引文数量、自引数量和 h 指数。

结果

共确定了 274 名外科医生。该队列的平均出版物数量±标准差、引文数量和 h 指数分别为 60.5±77.2、1765±4024 和 16.0±15.0。整个队列的自我引用率为 3.23%。排除自引后，引文数量平均减少至 1708±3887，h 指数减少至 15.8±14.6。77%（210/274）的外科医生 h 指数保持不变。只有 5%（15/274）的外科医生 h 指数变化大于一个整数，没有外科医生的 h 指数变化大于三个整数。
