IntroductionLearner workload during simulated team-based resuscitations is not well understood. In this descriptive study, we measured the workload of learners in different team roles during simulated paediatric cardiopulmonary resuscitation.MethodsPaediatric emergency nurses and paediatric and emergency medicine residents formed teams of four to eight and randomised into roles to participate in simulation-based, paediatric resuscitation. Participant workload was measured using the NASA Task Load Index, which provides an average workload score (from 0 to 100) across six subscores: mental demand, physical demand, temporal demand, performance, frustration and mental effort. Workload is considered low if less than 40, moderate if between 40 and 60 and high if greater than 60.ResultsThere were 210 participants representing 40 simulation teams. 138 residents (66%) and 72 nurses (34%) participated. Team lead reported the highest workload at 65.2±10.0 (p=0.001), while the airway reported the lowest at 53.9±10.8 (p=0.001); team lead had higher scores for all subscores except physical demand. Team lead reported the highest mental demand (p<0.001), while airway reported the lowest. Cardiopulmonary resuscitation coach and first responder reported the highest physical demands (p<0.001), while team lead and nurse recorder reported the lowest (p<0.001).ConclusionsWorkload for learners in paediatric simulated resuscitation teams was moderate to high and varied significantly based on team role. Composition of workload varied significantly by team role. Measuring learner workload during simulated resuscitations allows improved processes and choreography to optimise workload distribution.

Abstract Background Breast surgery has evolved with more focus on improving cosmetic outcomes, which requires increased operative time and technical complexity. Implications of these technical advances in surgery for the surgeon are unclear, but they may increase intraoperative demands, both mentally and physically. We prospectively evaluated mental and physical demand across breast surgery procedures, and compared surgeon ergonomic risk between nipple-sparing (NSM) and skin-sparing mastectomy (SSM) using subjective and objective measures. Methods From May 2017 to July 2017, breast surgeons completed modified NASA-Task Load Index (TLX) workload surveys after cases. From January 2018 to July 2018, surgeons completed workload surveys and wore inertial measurement units to evaluate their postures during NSM and SSM cases. Mean angles of surgical postures, ergonomic risk, survey items, and patient factors were analyzed. Results Procedural duration was moderately related to surgeon frustration, mental and physical demand, and fatigue (p < 0.001). NSMs were rated 23% more physically demanding (M = 13.3, SD = 4.3) and demanded 28% more effort (M = 14.4, SD = 4.6) than SSMs (M = 10.8, SD = 4.7; M = 11.8, SD = 5.0). Incision type was a contributing factor in workload and procedural difficulty. Left arm mean angle was significantly greater for NSM (M = 30.1 degrees, SD = 6.6) than SSMs (M = 18.2 degrees, SD = 4.3). A higher musculoskeletal disorder risk score for the trunk was significantly associated with higher surgeon physical workload (p = 0.02). Conclusion Nipple-sparing mastectomy required the highest surgeon-reported workload of all breast procedures, including physical demand and effort. Objective measures identified the surgeons’ left upper arm as being at the greatest risk for a work-related musculoskeletal disorder, specifically from performing NSMs.

IntroductionInvestigating acute multifactorial undifferentiated breathlessness and understanding the driving inflammatory processes can be technically challenging in both adults and children. Being able to validate noninvasive methods such as breath analysis would be a huge clinical advance. The ReCIVA® device allows breath samples to be collected directly onto sorbent tubes at the bedside for analysis of exhaled volatile organic compounds (eVOCs). We aimed to assess the feasibility of using this device in acutely breathless patients.MethodsAdults hospitalised with acute breathlessness and children aged 5–16 years with acute asthma or chronic stable asthma, as well as healthy adult and child volunteers, were recruited. Breath samples were collected onto sorbent tubes using the ReCIVA® device and sent for analysis by means of two-dimensional gas chromatography-mass spectrometry (GCxGC-MS). The NASA Task Load Index (NASA-TLX) was used to assess the perceived task workload of undertaking sampling from the patient's perspective.ResultsData were available for 65 adults and 61 children recruited. In total, 98.4% of adults and 75.4% of children were able to provide the full target breath sample using the ReCIVA® device. NASA-TLX measurements were available in the adult population with mean values of 3.37 for effort, 2.34 for frustration, 3.8 for mental demand, 2.8 for performance, 3.9 for physical demand and 2.8 for temporal demand.DiscussionThis feasibility study demonstrates it is possible and acceptable to collect breath samples from both adults and children at the bedside for breathomics analysis using the ReCIVA® device.

Close-to-nature (CTN) forestry offers many advantages, but makes management more complex and generally results in lower harvesting productivity and higher harvesting cost. While the higher harvesting cost of CTN is widely acknowledged, few ever consider the potential impact on operator workload, as the harvesting task becomes more complex. This study aimed to determine the mental workload of harvester operators under two silvicultural regimes: »pure conifer« stand and »mixwood« stand. In total, 13 harvester operators with varying experience levels were monitored for work performance and mental workload when operating a harvester simulator in two virtual stands designed according to the above-mentioned silvicultural regimes. Mental workload was assessed using the NASA Task Load Index (NASA-TLX) interview method and heart rate variability measurements, during two 30-minute test sessions performed in the »pure conifer« and the »mixwood« stand, respectively. As expected, operating in a more diversified »mixwood« stand resulted in a marked productivity loss, estimated between 40 and 57%. The study also confirmed the increased aggravation of mental demand, effort and frustration experienced by the operators when passing from the »pure conifer« stand to the »mixwood« stand. Such increase in mental workload was independent of the age and experience of the operators. Results can be used to paint a more holistic picture of CTN forestry and its implications for harvester operators. Besides increasing the number of subjects being monitored, future studies should focus on live forest operations.

We sought to assess the impact of procedural skills simulation training on residents’ competence in performing critical resuscitation skills. Our study was a prospective, cross-sectional study of residents from three residency training programs (Family Medicine, Emergency Medicine and Internal Medicine) at the University of Calgary. Participants completed a survey measuring competence in the performance of the procedural skills required to manage hemodynamic instability. The study intervention was an 8 hour simulation based training program focused on resuscitation procedure psychomotor skill acquisition. Competence was criterion validated at the Right Internal Jugular Central Venous Catheter Insertion station by an expert observer using a standardized checklist (Observed Structured Clinical Examination (OSCE) format). At the completion of the simulation course participants repeated the self-assessment survey. Descriptive Statistics, Cronbach’s alpha, Pearson’s correlation coefficient and Paired Sample t-test statistical tools were applied to the analyze the data. Thirty-five of 37 residents (9 FRCPC Emergency Medicine, 4 CCFP-Emergency Medicine, 17 CCFP, and 5 Internal Medicine) completed both survey instruments and the eight hour course. Seventy-two percent of participants were PGY-1 or 2. Mean age was 30.7 years of age. Cronbach’s alpha for the survey instrument was 0.944. Pearson’s Correlation Coefficient was 0.69 (p < 0.001) for relationship between Expert Assessment and Self-Assessment. The mean improvement in competence score pre- to post-intervention was 6.77 (p < 0.01, 95% CI 5.23-8.32). Residents from a variety of training programs (Internal Medicine, Emergency Medicine and Family Medicine) demonstrated a statistically significant improvement in competence with critical resuscitation procedural skills following an intensive simulation based training program. Self-assessment of competence was validated using correlation data based on expert assessments. Dawson S. Procedural simulation: a primer. J Vasc Interv Radiol. 2006; 17(2.1):205-13.

BACKGROUND: The contrast between a bright computer screen and a dark ambient environment may influence comfort of the users, especially on their eyes. OBJECTIVE: The objective of this research is to identify the optimal desktop lighting for the comfortable use of the computer screen in a dark environment. METHODS: An experiment was designed where seven illumination setups were introduced for the users to perform their leisure tasks on a computer screen. Fifteen healthy subjects participated in the experiments. During each session, durations of the eye blinks, fixations and saccades of the user were recorded by an eye tracker. His/her neck and trunk movements were recorded by a motion tracking system as well. The comfort/discomfort questionnaire, localized postural discomfort questionnaire, NASA task load index and computer user questionnaire were used to record the overall comfort/discomfort, the local perceived physical discomfort, the cognitive workload, and general/eye health problems, respectively. RESULTS: Subjective and objective measurement results indicated that users felt more comfortable with high intensity warm lights using a computer screen. We also identified that the eye fixation durations, as well as the scores of two questions in the computer user questionnaire, have significant negative correlations with comfort. On the other side, the durations of blinks and the scores of three questions in the computer user questionnaire, were significantly correlated with discomfort. CONCLUSION: The warm (3000K) and high intensity (1500 lux) light reduced the visual and cognitive fatigue of the user and therefore improve the comfort of the user during the use of a computer screen.

Abstract Background Pediatric emergency medicine training is in its infancy in India. Simulation provides an educational avenue to equip trainees with the skills to improve pediatric care. We hypothesized that a simulation-based curriculum can improve Indian post-graduate emergency medicine (EM) trainees’ self-efficacy, knowledge, and skills in pediatric care. Methods We designed a simulation-based curriculum for management of common pediatric emergencies including sepsis, trauma, and respiratory illness and pediatric-specific procedures including vascular access and airway skills. Training included didactics, procedural skill stations, and simulation. Measures included a self-efficacy survey, knowledge test, skills checklist, and follow-up survey. Results were analyzed using the Wilcoxon signed-rank test and paired-samples t test. A 6-month follow-up survey was done to evaluate lasting effects of the intervention. Results Seventy residents from four academic hospitals in India participated. Trainees reported feeling significantly more confident, after training, in performing procedures, and managing pediatric emergencies (p < 0.001). After the simulation-based curriculum, trainees demonstrated an increase in medical knowledge of 19% (p < 0.01) and improvement in procedural skills from baseline to mastery of 18%, 20%, 16%, and 19% for intubation, bag-valve mask ventilation, intravenous access, and intraosseous access respectively (p < 0.01). At 6-month follow-up, self-efficacy in procedural skills and management of pediatric emergencies improved from baseline. Conclusions A simulation-based curriculum is an effective and sustainable way to improve Indian post-graduate EM trainees’ self-efficacy, knowledge, and skills in pediatric emergency care.

Psychophysiological measures can be used to determine whether a particular display produces a general difference in brain function. Such information might be valuable in efforts to improve usability in display design. In this preliminary study, we aimed to use the electroencephalography (EEG) task load index (TLI), given by the ratio of mean frontal midline theta energy to mean parietal alpha energy, to provide insight into the mental effort required by participants performing intuition-inducing and analysis-inducing tasks. We employed behavioral measures (reaction time and percent correct), and a subjective measure (NASA-Task Load Index) to validate the objective measure (TLI). The results we obtained were consistent with our hypothesis that mental effort required for analysis-inducing tasks would be different from that required for intuition-inducing tasks. Although our sample size was small, we were able to obtain a significant positive correlation between NASA-Task Load Index and TLI.

Giving excessive workloads causes work stress both physically and psychologically and emotional reactions. The excess workload experienced by drivers and swampers at PT XYZ results in reduced attention at work, decreased work motivation, and decreased skill levels, thus affecting drivers and swampers productivity and the chance of a work accident is very high. This study aims to measure the Mental Workload of Job Driver and Swampers Fuel Tank Using the NASA-TLX Method. The NASA-TLX score obtained 93.8, driver 2  get 83.7, driver 3  91.3, swamper 1  91, swamper 2 89.5, and swamper 3 94.7. Elements of mental workload that are very influential are Mental Demand with a percentage of 22%, Effort 20%, Physical Demand 18%, Own Performance 15%, Frustation Level 15% and Temporal Demand 12%.
