Respondent characteristics.

Importance
The COVID-19 pandemic stressed the healthcare field, resulting in a worker exodus at the onset and throughout the pandemic and straining healthcare systems. Female healthcare workers face unique challenges that may impact job satisfaction and retention. It is important to understand factors related to healthcare workers’ intent to leave their current field.
Objective
To test the hypothesis that female healthcare workers were more likely than male counterparts to report intention to leave.
Design
Observational study of healthcare workers enrolled in the Healthcare Worker Exposure Response and Outcomes (HERO) registry. After baseline enrollment, two HERO ‘hot topic’ survey waves, in May 2021 and December 2021, ascertained intent to leave. Unique participants were included if they responded to at least one of these survey waves.
Setting
HERO registry, a large national registry that captures healthcare worker and community member experiences during the COVID-19 pandemic.
Participants
Registry participants self-enrolled online and represent a convenience sample predominantly composed of adult healthcare workers.
Exposure(s)
Self-reported gender (male, female).
Main outcome
Primary outcome was intention to leave (ITL), defined as having already left, actively making plans, or considering leaving healthcare or changing current healthcare field but with no active plans. Multivariable logistic regression models were performed to examine the odds of intention to leave with adjustment for key covariates.
Results
Among 4165 responses to either May or December surveys, female gender was associated with increased odds of ITL (42.2% males versus 51.4% females reported intent to leave; aOR 1.36 [1.13, 1.63]). Nurses had 74% higher odds of ITL compared to most other health professionals. Among those who expressed ITL, three quarters reported job-related burnout as a contributor, and one third reported experience of moral injury.
Conclusions and relevance
Female healthcare workers had higher odds of intent to leave their healthcare field than males. Additional research is needed to examine the role of family-related stressors.
