Integrity in cardiovascular imaging research.

OBJECTIVE

To gain more insight in scientific integrity in the field of cardiovascular imaging research by conducting a survey among all corresponding authors who published in cardiovascular imaging journals.

METHODS

Corresponding authors who published in one of eight major cardiovascular imaging journals in 2021 were requested to complete a questionnaire about scientific integrity in the field of cardiovascular imaging.

RESULTS

Responses from 160 corresponding authors were received. The majority of respondents had a medical doctor degree (81.1%), held an academic position (93.8%, of which 44.0% as full professor), and had >10 years of research experience (72.5%). Overall confidence in the integrity of published scientific work in cardiovascular imaging was high, with a median score of 8 out of 10 (IQR 2). 5 respondents (3.1%) declared having committed scientific fraud in the past 5 years and 38 respondents (23.8%) declared having witnessed or suspected scientific fraud by anyone from their department in the past 5 years. 85.6% of respondents think that publication bias is present. 50% of respondents declared that any of their publications in the past 5 years had a co-author who actually did not deserve this co-authorship.

CONCLUSION

Experts in the field report that several forms of scientific fraud, publication bias, and honorary authorship are present in cardiovascular imaging research. Despite these reports of academic dishonesty, overall confidence in the integrity of cardiovascular imaging research is deemed high.
