Background People who experience serious mental health issues are at an elevated risk of premature death. Research demonstrates that serious adverse events in mental health settings can be avoided through the recognition and appropriate response to early signs of physiological deterioration.

Aim To evaluate the self-reported confidence of mental health nurses in recognising physically deteriorating patients in a mental health setting.

Method This pilot study used a quantitative survey to capture 22 mental health nurses’ confidence in clinical decision-making before and after an educational workshop using the National Early Warning Score (NEWS). Participants were requested to make clinical decisions about the management of two case studies (patient A and patient B). The NEWS workshop was piloted in a ward for older people with mental health issues.

Results Mental health nurses’ levels of confidence in managing physically deteriorating patients improved after the NEWS workshop.

Conclusion Following the implementation of a NEWS workshop, mental health nurses demonstrated improved confidence in clinical decision-making about physically deteriorating patients, albeit in an educational setting.
