Key result
Lower HRV correlates with higher perceived stress in ICU nurses on night and extended shifts.
Why the study?
The relationship between physiological stress indicators such as HRV and psychometric assessments has not been thoroughly explored in ICU nursing staff.
Does Heart Rate Variability (HRV) correlate with psychometric assessments of stress and burnout in ICU nursing staff?
Population
24 ICU healthcare professionals at a University Hospital in Madrid, Spain
Comparison
HRV metrics and psychometric assessments of stress and anxiety
Design
Observational cross-sectional pilot study

HRV metrics correlated with perceived stress in ICU nurses; supports hypothesis-generating monitoring but requires larger longitudinal validation before practice change.

Does Heart Rate Variability (HRV) correlate with psychometric assessments of stress and burnout in ICU nursing staff?
HRV metrics, particularly the LF/HF ratio, significantly correlate with psychometric stress assessments, suggesting HRV could be a valuable objective tool for monitoring stress and burnout in ICU nursing staff.
Rubio-López et al. (2024) conducted a cross-sectional in Stress and burnout (n=24). Night and extended shifts was evaluated on Correlation between HRV metrics and psychometric assessments of stress and anxiety. Significant negative correlations were observed between heart rate variability metrics and perceived stress levels in ICU nursing staff, with night and extended shifts associated with elevated stress.
