Baevsky’s Enhanced Stress Technique identified significant physiological changes in HRV linked to combined mental and physical stress events in ICU nurses, with AUC of 85.46.
Does continuous wrist-worn HRV and accelerometer monitoring using Baevsky's Enhanced Stress Technique differentiate between mental and physical stress in ICU nurses?
Wrist-worn sensors measuring HRV and accelerometer data can effectively differentiate between mental and physical occupational stress in ICU nurses using Baevsky's Enhanced Stress Technique.
Absolute Event Rate: 0% vs 0%
Objective This study examined a novel method to differentiate between mental and physical stress using Baevsky’s Enhanced Stress Technique. Background Occupational stress events, whether mental or physical, are handled by the sympathetic and parasympathetic nervous systems, which have been shown to be associated with heart rate variability (HRV), but have not been previously differentiated. Method Naturalistic HRV and accelerometer data were measured continuously using wrist-worn sensors during a typical 12-h direct-care nursing shift (28 ICU nurses). Physical and mental stress events were calculated using the Baevsky’s Stress Index, and Activity Index was used to investigate their differences between mental and combined mental and physical stress. Results Root mean square of successive differences between heartbeats (RMSSD), which is associated with the parasympathetic nervous system activity as well as low-frequency power/high-frequency power (LF/HF ratio), and the alpha value of detrended fluctuation analysis (DFA a2), which are associated with the balance between sympathetic and parasympathetic nervous system activity, were the most predictive features of stress events (accounting for AUC of 85.46). Conclusion Baevsky’s Enhanced Stress Technique shows promise in assessing occupational mental stress among ICU nurses. There were more persistent and significant physiological changes in HRV associated with combined mental and physical stress events. Application Findings suggest a new stress measurement method for classifying occupational mental stress. Measurement using wrist-worn accelerometer and HRV data sources has pragmatic relevance to the design of real-time, noninvasive, and cost-efficient stress monitoring tools relevant to applications in high-stress work environments.
