Acute mental stress and surgical performance.

ABSTRACT: Background:Stress has been shown to impact adversely on multiple facets critical to optimal performance. Advancements in wearable technology can reduce barriers to observing stress during surgery. This study aimed to investigate the association between acute intraoperative mental stress and technical surgical performance. Methods:Continuous electrocardiogram data for a single attending surgeon were captured during surgical procedures to obtain heart rate variability (HRV) measures that were used as a proxy for acute mental stress. Two different measures were used: root mean square of successive differences (RMSSD) and standard deviation of RR intervals (SDNN). Technical surgical performance was assessed on the Operating Room Black Box® platform using the Generic Error Rating Tool (GERT). Both HRV recording and procedure video recording were time-stamped. Surgical procedures were fragmented to non-overlapping intervals of 1, 2 and 5 min, and subjected to data analysis. An event was defined as any deviation that caused injury to the patient or posed a risk of harm. Results:Rates of events were significantly higher (47-66 per cent higher) in the higher stress quantiles than in the lower stress quantiles for all measured interval lengths using both proxy measures for acute mental stress. The strongest association was observed using 1-min intervals with RMSSD as the HRV measure (P < 0·001). Conclusion:There is an association between measures of acute mental stress and worse technical surgical performance. Further study will help delineate the interdependence of these variables and identify triggers for increased stress levels to improve surgical safety.

Project description:BackgroundSimulation-based training in medical education has become a common method to develop both technical and non-technical skills in teams. Mental rehearsal (MR) is the cognitive act of simulating a task in our heads to pre-experience tasks imaginatively. It has been used widely to improve individual and collective performance in fields outside healthcare, and offers potential for more efficient training in time-pressured surgical and medical team contexts. This study aimed to review the available literature to determine the impact of MR on team performance and non-technical skills in healthcare.MethodsMEDLINE, Embase, British Educational Index, CINAHL, Web of Science, PsycInfo and Cochrane databases were searched for the period 1994-2018. The primary outcome measure was improvement in team performance and non-technical skills. Study quality of RCTs was assessed using the Medical Education Research Quality Instrument. The reported impacts of MR in all included studies were mapped on to the Kirkpatrick framework for evaluation of educational interventions.ResultsEight studies with 268 participants were identified that met the inclusion criteria, of which there were six randomized trials, one prospective pragmatic trial and one qualitative study. Three studies found MR to be effective in improving team non-technical skills. MR practices were varied and often poorly defined. MR benefited team non-technical skills when it was specifically designed to do so, but was not an automatic consequence of technical MR alone. The majority of studies demonstrated benefits of MR for technical performance, but only three showed positive impacts on teamwork. Overall the studies were of low quality and lacked sufficient discriminatory focus to examine impacts on teamwork dynamics.ConclusionMR can improve technical performance, but the benefits on non-technical skills are less clear. Future research should look at longitudinal mixed-method evaluation designs and focus on real clinical teams.
