Analysis of Practices to Promote Reproducibility and Transparency in Anaesthesiology Research: Are Important Aspects Hidden Behind the Drapes?

IntroductionReliable, high-quality research is essential to the field of anaesthesiology. Reproducibility and transparency has been investigated in the biomedical domain and in the social sciences, with both lacking to provide necessary information to reproduce the study findings. In this study, we investigated 14 indicators of reproducibility in anaesthesiology research.\n\nMethodsWe used the National Library of Medicine (NLM) catalogue to search for all anaesthesiology journals that are MEDLINE indexed and provided English texts. PubMed was searched with the list of journals to identify all publications from January 1, 2014 to December 31, 2018. We randomly sampled 300 publications that fit the inclusion criteria for our analysis. Data extraction was then conducted in a blinded, duplicate fashion using a pilot-tested Google form.\n\nResultsThe PubMed search of these journals identified 171,441 publications, with 28,310 being within the time frame. From the 300 publications sampled, 296 full-text publications were accessible. Most of the studies did not include materials or protocol availability statements. The majority of publications did not provide a data analysis script statement (121/122, 99% [98% to 100%]) or a preregistration statement (94/122, 77% [72% to 81%]).\n\nConclusionAnaesthesiology research needs to drastically improve indicators of reproducibility and transparency. By making research publically available and improving accessibility to detailed study components, primary research can be reproduced in subsequent studies and help contribute to the development of new practice guidelines.

Authorship inflation and author gender in pulmonology research.

IntroductionHonorary authorship and equal gender representation are two pressing matters in scientific research. Honorary authorship is the inclusion of authors who do not meet the criteria established by the International Committee of Medical Journal Editors (ICMJE) authorship guidelines. The inclusion of honorary authors in the medical literature has led to an increase of the number of authors on studies and a decrease in single author studies in various fields.\n\nMethodsOur primary objective was to assess authorship trends in two major pulmonology journals (selected on the basis of Google Scholar rankings): Thorax and American Journal of Respiratory and Critical Care Medicine. We reviewed all articles published in both journals in the years 1994, 2004, and 2014 using Web of Science and extracted data such as number of authors and gender of the first and last authors.\n\nResultsThe total number of authors steadily increased from 1994 to 2014. The median number of authors grew from about four in 1994 to nearly seven in 2014, which is approximately a 75% increase. When we compiled all the data, we found the percentage of female authors from both journals had increased from 17% to 29.9% during the study period.\n\nDiscussionWe found an increase in the average number of authors on pulmonology publications between 1994 and 2014 as well as an increase in the number of females with a lead or main author position. This may be due to a variety of factors, such as increased team science. However, our data in conjunction with data from other areas of medicine, indicate that honorary authorship may be contributing to the trends we identified.
