Background: There is an increasing demand for an objective predictor of burnout. HRV has shown promising results in measuring stress and fatigue, two important predictors of burnout. We aim to evaluate whether HRV can be used as an indicator of the amount of stress, fatigue and recovery in surgeons and residents during an operating-day, including intraoperatively, and a non-operating day. Methods: Normalized time- and frequency-domain measures were used for analysis. Intraoperative correlations of stress and fatigue with HRV parameters were tested using a Pearson-Correlation test. For the comparison of the operating-day and non-operative day, all HRV parameters Z-scores were plotted, visually inspected, and in case of differences, tested using repeated measures ANOVA. Recovery was visually inspected. Results: A decrease in the IBImean, HF-band and increase in LF/HF-ratio is found in the operating-day vs. non-operative day, followed by a slower rise in HF-band and IBI-mean, indicating delayed recovery. Intraoperative, stress negatively correlates with almost all HRV parameters in surgeons, indicating increased cognitive effort and decreased parasympathetic and sympathetic activation. In residents, a negative correlation between difficulty and IBIsd is solely present (r = -.206, p < .05). Conclusion: Decreased relaxation and increased fatigue as measured by HRV is found during the operating-day compared to the non-operative day, followed by a prolonged recovery period. Intraoperative stress and fatigue appear to cause a change in HRV parameters in surgeons, but HRV remains mostly unaffected in residents, which may be caused by lower feeling of responsibility, or conscious or unconscious manipulation of the answers. HRV shows promising in the measurement of stress, fatigue and recovery, but further research is needed to confirm its use as a predictor of burnout.
