A Longitudinal Study of Gender Parity Trends of General Membership and Leadership in the Neurocritical Care Society between 2002 and 2019

Background: Several studies in critical care and neurology demonstrate women under-representation in professional societies; representation trends within the Neurocritical Care Society (NCS) are unknown. We examined longitudinal gender parity trends in membership and leadership within NCS. Methods: A retrospective study of NCS membership and leadership rosters was conducted. To determine gender, self-reported binary gender was extracted. For individuals without recorded gender, a systematic Web-based search to identify usage of gender-specific pronouns in publicly available biographies was performed. According to previously published methods, available photographs were utilized to record presumed gender identification in the absence of available pronoun descriptors. We analyzed available data longitudinally from 2002 to 2019 and performed descriptive statistical and linear regression analyses. Results: In overall membership, the proportion of women members demonstrated an average 11% increase between 2005 and 2018 (95% confidence interval (CI) − 8.1 to 30.1, p = 0.08). The proportion of women Board of Directors (BOD) members increased significantly over time to 50% in 2019. There was an increase in women Officers from 0% in the first 3 years (2002–2004) to 40% in 2019, with two women Presidents out of 17 from 2002 to 2019. For available Executive Committee rosters, there was a statistically significant nearly 3% increase per year (95% CI 1.5–4; p = 0.0007) in the proportion of women members. Rosters for Committee members and chairpersons were also incomplete, but in an analysis of the available data, there was a statistically significant increase of 5% per year analyzed (95% CI 0.5–9.7; p = 0.04) in the proportion of women Committee members. We also found a statistically significant 4.3% increase per year analyzed (95% CI 2.4–6.1; p = 0.003) in the proportion of women Committee chairpersons. Conclusions: This is the first study of longitudinal gender parity trends within neurocritical care. We report that from 2002 to 2019, the NCS has undergone a significant increase in women representation in general membership, committee membership, and leadership positions.
