Accessible Summary
What is known on the subject?
Trauma among psychiatric nurses and other healthcare workers is related to workplace violence, but other risk factors may also contribute, including those occurring before, during or after workplace violence.
What does this paper add to existing knowledge?
Most previously identified PTSD risk factors were not tested or supported in research with psychiatric nurses, although there is promising evidence for risk factors including severe or injurious assault, cumulative exposure, burnout, and other worker characteristics.
We identify directions for research needed to improve knowledge, including collecting data before nurses experience workplace violence, defining workplace risk factors consistently and conducting and reporting qualitative analysis.
What are the implications for practice?
Provide training in risk assessment and violence prevention to psychiatric nurses.
Offer mental health support to those exposed to violence, especially with cumulative exposure.
Introduction
Psychiatric nurses are at risk of workplace violence and post‐traumatic stress disorder (PTSD). There is limited understanding of pre‐trauma and post‐trauma risk factors.
Aim
Our aim was to review factors associated with workplace PTSD in psychiatric nurses.
Method
We searched quantitative and qualitative studies from 1980 to 2019 in 23 databases plus s for studies on psychiatric hospital nursing staff, potentially traumatic workplace events, workplace factors and PTSD. Following duplicate (n = 10,064) and full‐text (n = 199) screening, data were extracted in duplicate from 19 studies. Using best‐fit framework synthesis, we identified workplace violence, pre‐trauma and post‐trauma risk factors.
Results
Six variables yielded evidence in at least two empirical studies scoring at least 6/8 on a quality measure, or one such study plus more than one other study (“promising”: severe/injurious assault, cumulative exposure, burnout, poor mental health, low compassion satisfaction, neuroticism). Four were supported by at least one better quality study or at least two others (“suggestive”: gender, poor training, any physical aggression exposure, compassion fatigue).
Discussion
Pre‐trauma measures, consistent definitions of workplace exposures and thorough reporting of quantitative results are needed to improve research.
Implications for Practice
Violence prevention and mental health care for exposed nurses appear the most promising targets for PTSD prevention. Therefore, it is particularly important to understand workplace violence and mental health among nurses working in psychiatric hospitals.
