Objective: To analyze gender differences in authorship of North American (Canadian and American) and international published otolaryngology-head and neck surgery (OHNS) clinical practice guidelines (CPG) over a 17-year period.
Methods: Clinical practice guidelines published between 2005 and 2022 were identified through the Canadian Agency for Drugs and Technology in Health (CADTH) search strategy in MEDLINE and EMBASE. Studies were included if they were original studies, published in the English language, and encompassed Canadian, American, or international OHNS clinical practice guidelines.
Results: A total of 145 guidelines were identified, encompassing 661 female authors (27.4%) and 1756 male authors (72.7%). Among OHNS authors, women and men accounted for 21.2% and 78.8% of authors, respectively. Women who were involved in guideline authorship were 31.0% less likely to be an otolaryngologist compared to men. There were no gender differences across first or senior author and by subspeciality. Female otolaryngologist representation was the greatest in rhinology (28.3%) and pediatrics (26.7%). American guidelines had the greatest proportion of female authors per guideline (34.1%) and the greatest number of unique female authors (33.2%).
Conclusion: Despite the increasing representation of women in OHNS, gender gaps exist with regards to authorship within clinical practice guidelines. Greater gender diversity and transparency is required within guideline authorship to help achieve equitable gender representation and the development of balanced guidelines with a variety of viewpoints.
