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.

The Relationship

  Prolonged occupational stress can lead to the syndrome of job burnout. Workload was one of the factors that can cause the burnout. The main objective of this study was to determine the levels of job burnout and their relationships with workload among the medical staff. The key roles of medical staff in a hospital can be broadly separated into four areas which were the doctors, nurses, allied health professionals and support staff. Eighty medical staff from hospital volunteered to participate in this research. Different data were gathered using the Maslach Burnout Inventory (MBI), NASA-Task Load Index and Demographic questionnaire. The significance of the study was to investigate the relationship between the job burnout and workload among the medical staff in hospitals. The overall level of workload and job burnout was moderate. The results indicated that workload and job burnout among medical staff in hospitals was at moderate level. There was a significant relationship between workload and job burnout in this research.

Relatively little research has investigated subjective workload assessment during tasks involving both physical and mental demands. Development of more comprehensive workload assessment tools depends on understanding the effects of physical and mental activity on an individual's perception of workload. This study investigated the interaction between the two types of demands and the potential effects of such interactions on subjective workload assessment and performance. Common subjective workload assessment tools (Borg CR-10 Scale, Visual Analog Scale, NASA Task Load Index) were used to record changes in perceived workload during varying levels of physical and mental demands. Thirteen participants completed all conditions with the results summarized to identify potential trends in the data. The results suggest that a physical demand component did not affect subjective mental workload assessment (p = 0.9916). in addition, the presence of mental demands did not affect physical workload assessment (p = 0.9183). High correlations were found between the subjective mental workload assessment scores and mental performance (r = −0.8 and–0.9).

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.

ObjectiveTo understand human factors (HF) contributing to disturbances during invasive cardiac procedures, including frequency and nature of distractions, and assessment of operator workload.MethodsSingle centre prospective observational evaluation of 194 cardiac procedures in three adult cardiac catheterisation laboratories over 6 weeks. A proforma including frequency, nature, magnitude and level of procedural risk at the time of each distraction/interruption was completed for each case. The primary operator completed a National Aeronautical and Space Administration (NASA) task load questionnaire rating mental/physical effort, level of frustration, time-urgency, and overall effort and performance.Results264 distractions occurred in 106 (55%) out of 194 procedures observed; 80% were not relevant to the case being undertaken; 14% were urgent including discussions of potential ST-elevation myocardial infarction requiring emergency angioplasty. In procedures where distractions were observed, frequency per case ranged from 1 to 16 (mean 2.5, SD ±2.2); 43 were documented during high-risk stages of the procedure. Operator rating of NASA task load parameters demonstrated higher levels of mental and physical workload and effort during cases in which distractions occurred.ConclusionsIn this first description of HF in adult cardiac catheter laboratories, we found that fewer than half of all procedures were completed without interruption/distraction. The majority were unnecessary and without relation to the case or list. We propose the introduction of a ‘sterile cockpit’ environment within catheter laboratories, as adapted from aviation and used in surgical operating theatres, to minimise non-emergent interruptions and disturbances, to improve operator conditions and overall patient safety.

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.

Learning And Performance

Performance benefits exist for an external focus of attention compared with an internal focus of attention for performance and learning (Wulf, 2013). It is unknown, however, if varying the number of verbal cues affects learning and performance. Focus of attention and the number of verbal cues were manipulated during a simulated handgun-shooting task. For the internal focus conditions, participants were told to focus on their hand, arm, and wrist, whereas the external focus instructions were to focus on the gun, gun barrel, and gun stock. To manipulate the number of verbal cues, participants received instruction to focus on a single verbal cue or multiple verbal cues. Shooting performance was assessed at baseline, acquisition, and at two separate retention phases (immediate, delayed) that included transfer tests. Participants completed the NASA—Task Load Index to assess workload following all trials. Participants who received one verbal cue performed significantly better during immediate retention than those who received three verbal cues. Participants who used external focus of attention instructions had higher performance and reported less workload at delayed retention compared to those who used internal focus instructions. This research provides further support for the benefits of an external focus and highlights the importance of minimizing the number of verbal cues.

The majority of Unmanned Aerial Vehicle (UAV) accidents can be directly related to human error. For this reason, standards and guidelines focusing on human factors have been published by various organizations such as Transport Canada, FAA, EASA, NASA and military agencies. The objective of this thesis is to present a methodology for designing a Ground Control Station (GCS) using available standards and guidelines for human factors. During the design process, a detailed analysis was performed using human factors methods to ensure all requirements were met; each phase of the design follows the guidelines presented in the compiled human factors standards and guidelines. The GCS interface was developed using advanced programming techniques and commercial off-the-shelf software. Moreover, an operator workload evaluation was carried out using NASA task load index for validation of design methodology. It was found that the applied methodology not only improved the pilot workload, but also ensured that all user and stakeholders’ requirements are met.

The main priority of middle ear surgery is to create a safe and optimal view of the surgical field, as well as the most accurate visualization of anatomical structures, which is a driving factor in the evolution of otosurgery. The additional information provided by three-dimensional (3D) images has been proven to improve understanding of the temporal bone anatomy and improve the operator’s ability to assess associated diseases, thereby optimizing surgical management. In the presented experimental research work, a new technique for visualizing the surgical field is described, which improves the quality of the operator’s work and expands the possibilities of middle ear surgery. On the basis of the Chair of Otorhinolaryngology of the Mechnikov North-Western State Medical University a remote adapter for an endoscopic tube was created, which allows you to broadcast the video image received from its distal end to virtual reality glasses. For a detailed understanding of the principle of information transmission in a new three-dimensional reality, we used concepts such as disparity and stereopsis. All research results were evaluated according to the NASA Task Load Index scale. Analyzing the results of the experiment, in the conditions of three-dimensional visualization of the surgical field, a lower level of subjective workload was revealed, which was regarded as a positive effect of the realization of the phenomenon of stereopsis, when performing manipulations on the middle ear.
