商业文献已经证明了网络和联系在职业发展中的重要性。这是一个在学术医学中很少研究的领域。（一级和二级合著者的数量），2008年至2012年的前瞻性队列研究，共收集了5787名哈佛医学院（HMS）的医学生，2008年1月1日，助理教授或全职教师的职级。使用负二项模型，多变量调整的预测连续网络达到评估根据排名。Poisson回归用于计算网络覆盖（四个类别）与两个结果（晋升或流失）之间关联的相对风险（RR）和95%置信区间（CI）。模型根据人口统计学、专业和生产力指标进行了调整。网络覆盖率与第一、最后和中间作者出版物的数量和h指数呈正相关。在助理教授中，男性和白人的网络覆盖率高于女性和代表性不足的少数民族（p < 0.001）。与2008年网络覆盖率最低的教师相比，在调整协变量后，到2012年，网络覆盖率最高的教师晋升为助理教授的可能性是最高类别教师的三倍（RR：3.16，95%CI：2.60，3.86; p趋势< 0.001）。网络覆盖与助理晋升为副教授呈正相关（RR：1.82，95% CI：1.32，2.50; p趋势< 0.001）。2008年网络覆盖率最高类别的人到2012年离开HMS的可能性比最低类别的人低17%（RR：0.83，95%CI 0.70，0.98）。这些结果表明，合著者网络指标可以为了解学术医学的教师晋升和保留提供有用的信息。他们可以而且应该在其他机构进行调查。
Business literature has demonstrated the importance of networking and connections in career advancement. This is a little-studied area in academic medicine.To examine predictors of intra-organizational connections, as measured by network reach (the number of first- and second-degree coauthors), and their association with probability of promotion and attrition.Prospective cohort study between 2008 and 2012.Academic medical center.A total of 5787 Harvard Medical School (HMS) faculty with a rank of assistant professor or full-time instructor as of January 1, 2008.Using negative binomial models, multivariable-adjusted predictors of continuous network reach were assessed according to rank. Poisson regression was used to compute relative risk (RR) and 95 % confidence intervals (CI) for the association between network reach (in four categories) and two outcomes: promotion or attrition. Models were adjusted for demographic, professional and productivity metrics.Network reach was positively associated with number of first-, last- and middle-author publications and h-index. Among assistant professors, men and whites had greater network reach than women and underrepresented minorities (p < 0.001). Compared to those in the lowest category of network reach in 2008, instructors in the highest category were three times as likely to have been promoted to assistant professor by 2012 (RR: 3.16, 95 % CI: 2.60, 3.86; p-trend < 0.001) after adjustment for covariates. Network reach was positively associated with promotion from assistant to associate professor (RR: 1.82, 95 % CI: 1.32, 2.50; p-trend < 0.001). Those in the highest category of network reach in 2008 were 17 % less likely to have left HMS by 2012 (RR: 0.83, 95 % CI 0.70, 0.98) compared to those in the lowest category.These results demonstrate that coauthor network metrics can provide useful information for understanding faculty advancement and retention in academic medicine. They can and should be investigated at other institutions.
