Summary
Management teams in German university cardiac surgery units show significant differences in publication output. Top-performing units publish 3.6 times more per member, highlighting disparities in research productivity.
Area of Science:
- Cardiac Surgery
- Medical Research
- Academic Medicine
Background:
- Publication performance of management teams in German university cardiac surgery units was evaluated.
- Benchmarking research output over a 10-year period was the primary goal.
Purpose of the Study:
- To assess and compare the publication performance of leadership teams in German university cardiac surgery departments.
- To identify variations in research productivity among these academic units.
Main Methods:
- PubMed database was searched for publications up to July 1, 2017.
- The 5-year impact factor (IF) from 2016 was used for journal evaluation.
- Publications and management team data were collected from unit websites.
Main Results:
- 2,535 publications with an average IF of 3.02 were identified.
- 68.9% of management team members published as first or last author.
- Significant disparities were found, with top units contributing 39.0% of publications and 42.7% of cumulative IF.
Conclusions:
- Top-performing cardiac surgery units published 3.6 times more per managing member than lower-performing units.
- The average cumulative impact factor per member was nearly five times higher in the top quintile.
- Further research is needed to determine if these publication activity differences exist in other surgical fields.
