Model-based individual life-spanning documentation in visceral surgery: a proof of concept.

Surgical documentation has many implications. However, its primary function is to transfer information about surgical procedures to other medical professionals. Thereby, written reports describing procedures in detail are the current standard, impeding comprehensive understanding of patient-individual life-spanning surgical course, especially if surgeries are performed at a timely distance and in diverse facilities. Therefore, we developed a novel model-based approach for documentation of visceral surgeries, denoted as 'Surgical Documentation Markup-Modeling' (SDM-M). For scientific evaluation, we developed a web-based prototype software allowing for creating hierarchical anatomical models that can be modified by individual surgery-related markup information. Thus, a patient's cumulated 'surgical load' can be displayed on a timeline deploying interactive anatomical 3D models. To evaluate the possible impact on daily clinical routine, we performed an evaluation study with 24 surgeons and advanced medical students, elaborating on simulated complex surgical cases, once with classic written reports and once with our prototypical SDM-M software. Leveraging SDM-M in an experimental environment reduced the time needed for elaborating simulated complex surgical cases from 354 ± 85s with the classic approach to 277 ± 128s. (p = 0.00109) The perceived task load measured by the Raw NASA-TLX was reduced significantly (p = 0.00003) with decreased mental (p = 0.00004) and physical (p = 0.01403) demand. Also, time demand (p = 0.00041), performance (p = 0.00161), effort (p = 0.00024), and frustration (p = 0.00031) were improved significantly. Model-based approaches for life-spanning surgical documentation could improve the daily clinical elaboration and understanding of complex cases in visceral surgery. Besides reduced workload and time sparing, even a more structured assessment of individual surgical cases could foster improved planning of further surgeries, information transfer, and even scientific evaluation, considering the cumulative 'surgical load.' Life-spanning model-based documentation of visceral surgical cases could significantly improve surgery and workload.

A Spanish version of the Three-Dimensional Work Fatigue Inventory (3D-WFI): factor structure, internal consistency, and criterion validity

BackgroundIn the working population, there are risks of overload due to physical, mental, and emotional demands. No instrument is available in Spanish to measure these three types of work fatigue (WF) separately. This paper adapts the Three-Dimensional Work Fatigue Inventory (3D-WFI) (2015), which is of American origin and measures and differentiates these three different types of WF. It has adequate psychometric properties at its root, as do the subsequent German (2018), Lebanese (2022), and Chinese (2023) adaptations.MethodsA total of 1100 workers (average age = 40 years) from economic sectors such as security and transportation of valuables, secondary and university educational institutions, and healthcare centers participated. They responded to the 3D-WFI, the Health-Related Quality of Life Index, and the Individual Strength Checklist for concurrent validity effects, together with items with sociodemographic and lifestyle variables.ResultsA confirmatory factor analysis with the total sample 3D-WFI supports its three-dimensionality; Cronbach’s alpha and Omega values are adequate by dimensions: for physical work fatigue (α = 0.92, Ω = 0.92), for mental work fatigue (α = 0.94. Ω = 0.94), and emotional work fatigue (α = 0.95, Ω = 0.95). The 3D-WFI correlates significantly with the Checklist Individual Strength (0.743), and a pattern of significant relationships is found between WF and antecedent variables (e.g., being exposed to heat and noise, emotional labor, concentration, and workwear), as well as some consequences of WF (for example, mental health, absenteeism, work satisfaction, and sleep quality).ConclusionsWe contribute here to the cross-cultural validity of the 3D-WFI, which can be used reliably and validly in the Chilean and probably Latin American working population. Some WF predictor variables are confirmed, as well as WF impacts on the absenteeism, health, and quality of life among workers.

Re-engaging with arts and cultural activities at the Life Rooms: ‘It’s given me spring’

BackgroundMersey Care NHS Foundation Trust’s Life Rooms initiative is an established and successful model of integrating arts and culture within NHS provision. In the face of COVID-19, the Life Rooms was restructured to provide a full suite of online resources. Following the lifting of restrictions, in-person arts provision returned to the Life Rooms sites. Additional evidence in respect of the impact on mental health and wellbeing of the return to in-person arts and cultural activities provided by the Life Rooms, as well as the relative merits of online and in-person arts and cultural activities, is needed to inform future planning around in-person, online, and/or hybrid provision.MethodsInterviews with practitioners delivering cultural and creative courses at the Life Rooms (n = 8) and users of the Life Rooms (n = 5) were conducted to explore the impact of the return to in-person arts provision at the Life Rooms, as well as the merits of online and in-person arts provision. Data were analysed using thematic analysis.ResultsThree overarching themes were identified: ‘Provision, access, and reach’; ‘Value of arts and creativity’; and ‘Challenges with the Life Rooms model in the new normal’. The findings demonstrate the critical role of arts and cultural provision in providing stigma-free environments to reconnect the vulnerable and isolated. As re-engagement remained slow, there is a need to be responsive to hesitation around re-engaging in-person. The Life Rooms online learning offer remained vital for those who are vulnerable or otherwise unable to access in-person activities.ConclusionsAs our findings show a demand for maintaining online provision that enables accessibility together with in-person provision that boosts community connectedness, ensuring continued online access alongside in-person delivery should be prioritised. As mental health demands could continue to grow in coming years as the pandemic evolves, in-person arts engagement could have an important role in meeting mental health needs.

Workload, general perceived stress, body function, musculoskeletal pain, and their mutual relationships in nurses - a pilot study.

Both physical and psychosocial risk factors contributing to musculoskeletal disorders occur in the professional nursing group, and previous literature suggested that their interaction may increase the risk of musculoskeletal pain among nurses. The aim of the study was to examine perceived workload and stress as well as physical findings and musculoskeletal complaints in nurses. The participants consisted of 42 female nurses, age range 23-60 years. They marked on a pain drawing the site/sites that was/were painful at the moment of testing, its duration and intensity. Thereafter they were examined using the movement and respiration domains from the Global Physiotherapy Examination (GPE). Furthermore, a subjective workload measure was made using the paper version of the National Aeronautics and Space Administration Task Load Index and stress was assessed using the Perceived Stress Questionnaire. Almost the entire study group declared that pain experienced in at least 1 location was chronic, i.e., had lasted ≥1 year (97%). The most frequent locations of pain were low back (22.4%) and cervical/head (21.6%) regions. In the GPE, most scores indicated restricted and reduced movement, with the subdomain flexibility having the highest deviation from the predefined standard. Furthermore, the results indicated hampered respiration, especially visible in standing position. Out of all workload scores, the highest was obtained for temporal demand. Perceived stress level was found to be moderate and significantly associated to chronic chest/ thoracic pain. Interestingly, the compression of thorax test positively correlated with mental (r = 0.42, p < 0.05) and physical demand (r = 0.35, p < 0.05), whereas the elbow drop test and temporal demand correlated negatively (r = -0.37, p < 0.05). To sum up, the majority of nurses participating in this study had long-lasting pain and limited flexibility of the body and hampered respiration, which both may enhance intensity of experienced musculoskeletal pain.

Better operating room efficiency and reduced staff demand: Individualised versus off-the-shelf total knee arthroplasty.

The purpose of this pilot cross-sectional study was to compare the operating room (OR) efficiency and intraoperative staff task load when performing individualised versus off-the-shelf (OTS) total knee arthroplasty (TKA). A consecutive series of 28 patients randomised (1:1) to receive either OTS TKA or individualised TKA were included. The OR staff workload was assessed with the NASA Task Load Index (TLX), a subjective grading system assessing mental demand, physical demand, temporal demand, performance, effort and frustration on a scale from 0 (very low) to 20 (very high). The time for patient preparation, surgical time, closureand total OR time was recorded to assess OR efficiency. Effect sizes of differences between OTS and individualised TKA were expressed as mean differences (MDs) with 95% confidence intervals (CIs). Patients in both cohorts were similar in age (OTS vs. individualised TKA (median [IQR]), 67 [63-76] vs. 71 [68-79]; p = 0.207) and body mass index (BMI) (29 [24-33] vs. 29 [26-31]; p = 0.807), and there were no significant differences in other preoperative characteristics. The OR staff perceived individualised TKA as less demanding than OTS TKA: Individualised TKA was rated significantly better across the six domains of the NASA TLX: mental demand by 5.6 points, physical demand by 6.3 points, temporal demand by 5.3 points, performance by 3.6 points, effort by 5.9 pointsand frustration by 5.8 points. Individualised TKA resulted in statistically significantly shorter mean total OR time (MD, 10 min; p = 0.018). The staff in the OR found that individualised TKA is less mentally, physicallyand temporally demanding than OTS TKA. The average total time spent in the OR during individualised TKA is 10 minless than during OTS TKA. This study constitutes a part of a larger registered randomised controlled trial comparing patient satisfaction following OTS versus individualised TKA (NCT04460989). Level III.

Debriefer cognitive load during Traditional Reflective Debriefing vs. Rapid Cycle Deliberate Practice interdisciplinary team training

BackgroundCognitive load impacts performance of debriefers and learners during simulations, but limited data exists examining debriefer cognitive load. The aim of this study is to compare the cognitive load of the debriefers during simulation-based team training (SbTT) with Rapid Cycle Deliberate Practice (RCDP) debriefing and Traditional Reflective Debriefing (TRD). We hypothesize that cognitive load will be reduced during RCDP compared to TRD.MethodsThis study was part of a large-scale, interdisciplinary team training program at Children’s Healthcare of Atlanta Egleston Pediatric Emergency Department, with 164 learners (physicians, nurses, medical technicians, paramedics, and respiratory therapists (RTs)). Eight debriefers (main facilitators and discipline-specific coaches) led 28 workshops, which were quasi-randomized to either RCDP or TRD. Each session began with a baseline medical resuscitation scenario and cognitive load measurement using the NASA Task Load Index (TLX), and the NASA TLX was repeated immediately following either TRD or RCDP debriefing. Raw scores of the NASA TLX before and after intervention were compared. ANOVA tests were used to compare differences in NASA TLX scores before and after intervention between the RCDP and TRD groups.ResultsFor all debriefers, mean NASA TLX scores for physical demands and frustration significantly decreased (− 0.8, p = 0.004 and − 1.3, p = 0.002) in TRD and mean perceived performance success significantly increased (+ 2.4, p < 0.001). For RCDP, perceived performance success increased post-debriefing (+ 3.6, p < 0.001), time demands decreased (− 1.0, p = 0.04), and frustration decreased (− 2.0, p < 0.001). Comparing TRD directly to RCDP, perceived performance success was greater in RCDP than TRD (3.6 vs. 2.4, p = 0.04). Main facilitators had lower effort and mental demand in RCDP and greater perceived success (p < 0.001).ConclusionRCDP had greater perceived success than TRD for debriefers. Main facilitators also report reduced effort and baseline mental demand in RCDP. For less experienced debriefers, newer simulation programs, or large team training sessions such as our study, RCDP may be a less mentally demanding debriefing methodology for facilitators.

Stand in surgeon's shoes: virtual reality cross-training to enhance teamwork in surgery.

Teamwork in surgery depends on a shared mental model of success, i.e., a common understanding of objectives in the operating room. A shared model leads to increased engagement among team members and is associated with fewer complications and overall better outcomes for patients. However, clinical training typically focuses on role-specific skills, leaving individuals to acquire a shared model indirectly through on-the-job experience. We investigate whether virtual reality (VR) cross-training, i.elet@tokeneonedotexposure to other roles, can enhance a shared mental model for non-surgeons more directly. Our study focuses on X-ray guided pelvic trauma surgery, a procedure where successful communication depends on the shared model between the surgeon and a C-arm technologist. We present a VR environment supporting both roles and evaluate a cross-training curriculum in which non-surgeons swap roles with the surgeon. Exposure to the surgical task resulted in higher engagement with the C-arm technologist role in VR, as measured by the mental demand and effort expended by participants ( ). It also has a significant effect on non-surgeon's mental model of the overall task; novice participants' estimation of the mental demand and effort required for the surgeon's task increases after training, while their perception of overall performance decreases ( ), indicating a gap in understanding based solely on observation. This phenomenon was also present for a professional C-arm technologist. Until now, VR applications for clinical training have focused on virtualizing existing curricula. We demonstrate how novel approaches which are not possible outside of a virtual environment, such as role swapping, may enhance the shared mental model of surgical teams by contextualizing each individual's role within the overall task in a time- and cost-efficient manner. As workflows grow increasingly sophisticated, we see VR curricula as being able to directly foster a shared model for success, ultimately benefiting patient outcomes through more effective teamwork in surgery.

Mental workload evaluation using weighted phase lag index and coherence features extracted from EEG data

Electroencephalogram (EEG) represents an effective, non-invasive technology to study mental workload. However, volume conduction, a common EEG artifact, influences functional connectivity analysis of EEG data. EEG coherence has been used traditionally to investigate functional connectivity between brain areas associated with mental workload, while weighted Phase Lag Index (wPLI) is a measure that improves on coherence by reducing susceptibility to volume conduction, a common EEG artifact. The goal of this study was to compare two methods of functional connectivity analysis, wPLI and coherence, in the context of mental workload evaluation. The study involved model development for mental workload domains and comparing their performance using coherence-based features, wPLI-based features, and a combination of both. Generalized linear mixed-effects model (GLMM) with the least absolute shrinkage and selection operator (LASSO) feature selection method was used for model development. Results indicated that the model developed using a combination of both feature types demonstrated improved predictive performance across all mental workload domains, compared to models that used each feature type individually. The R2 values were 0.82 for perceived task complexity, 0.71 for distraction, 0.91 for mental demand, 0.85 for physical demand, 0.74 for situational stress, and 0.74 for temporal demand. Furthermore, task complexity and functional connectivity patterns in different brain areas were identified as significant contributors to perceived mental workload (p-value<0.05). Findings showed the potential of using EEG data for mental workload evaluation which suggests that combination of coherence and wPLI can improve the accuracy of mental workload domains prediction. Future research should aim to validate these results on larger, diverse datasets to confirm their generalizability and refine the predictive models.

3D printing in anatomical lung segmentectomies: A randomized pilot trial

ObjectiveThis pilot study evaluated the impact of using a 3D printed model of the patient's bronchovascular lung anatomy on the mental workload and fatigue of surgeons during full thoracoscopic segmentectomy. DesignWe performed a feasibility pilot study of a prospective randomized controlled trial with 2 parallel arms. All included patients underwent digital 3D visual reconstruction of their bronchovascular anatomy and were randomized into the following two groups: Digital arm (only a virtual 3D model was available) and Digital + Object arm (both virtual and printed 3D models were available). The primary end-point was the surgeons’ mental workload measured using the National Aeronautics and Space Administration-Task Load Index (NASA-TLX) score. SettingBetween October 28, 2020 and October 05, 2021, we successively investigated all anatomic segmentectomies performed via thoracoscopy in the Thoracic Department of the Montsouris Mutualiste Institute, except for S6 segmentectomies and S4+5 left bi-segmentectomies. ParticipantsWe assessed 102 patients for anatomical segmentectomy. Among the, 40 were randomly assigned, and 34 were deemed analysable, with 17 patients included in each arm. ResultsComparison of the two groups, each comprising 17 patients, revealed no statistically significant difference in primary or secondary end-points. The consultation of the visual digital model was significantly less frequent when a 3D printed model was available (6 versus 54 consultations, p = 0.001). Notably, both arms exhibited high NASA-TLX scores, particularly in terms of mental demand, temporal demand, and effort scores. ConclusionIn our pilot study, 3D printed models and digital 3D reconstructions for pre-operative planning had an equivalent effect on thoracoscopic anatomic segmentectomy for experienced surgeons. The originality of this study lies in its focus on the impact of 3D printing of bronchovascular anatomy on surgeons, rather than solely on the surgical procedure.

Work and Retirement Among Women: The Health and Employment After Fifty Study.

Women increasingly work beyond age 50+ but their occupational health is under-researched. To investigate what jobs older contemporary women do, when they exit their jobs and what factors predict job exit. Data came from the Health and Employment After Fifty cohort, which recruited women aged 50-64 at baseline in 2013-14 and has followed them up annually collecting: demographic, lifestyle and work information. Exits from employment were mapped longitudinally over five follow-ups. Time-to-first event Cox regression analyses were used to identify risk factors for job exit. At baseline, 4436 women participated, 64% of whom were working. The proportions of women working at 50-54, 55-60 and over 60 years were 86%, 79% and 38%, respectively. Amongst all women, after adjustment for age, managing comfortably financially and not coping with the mental demands of the job were associated with exit. Risk factors for job exit differed in the age bands: 50-54; 55-59 and >60 years, reflecting socio-economic status, markers of health (musculoskeletal pain and poor self-rated health) and work factors (under-appreciation, job dissatisfaction, temporary/permanent contracts, coping with work's physical demands). Factors contributing to exit from work among older women differ by age group, after controlling for perceived financial position, age and mental demands of the job. A number of work characteristics predict job exit and suggest that employers can play an important role in supporting women to continue working until older ages. Identification and treatment of musculoskeletal pain could also enable work amongst older women.

Augmented reality in team-based search and rescue: Exploring spatial perspectives for enhanced navigation and collaboration

Indoor search and rescue (SAR) missions frequently encounter challenges due to complex spatial layouts and conditions of high stress. Augmented Reality (AR) has emerged as a promising tool to aid SAR efforts by offering spatial information through exocentric and egocentric perspectives. Specifically, AR systems introduce an egocentric perspective, overlaying detailed spatial information onto physical environments, which holds promise for navigating the complexities of indoor SAR operations. However, the effectiveness of these AR perspectives in a team-based SAR context remains underexplored. This study introduces a multi-user AR platform that combines reality capture with synchronized real-time spatial data and real-time cognitive load monitoring module to support team-based SAR missions. A human subject experiment (N = 64) was conducted with combined variations of spatial complexity and collaboration strategies to explore the efficacy of egocentric and exocentric navigation cues in aiding multi-agent SAR tasks. In the experiment, participants were asked to search for two consecutive targets while collaborating either parallelly, or hierarchically within a given time limit. Results indicated that egocentric cues offered limited benefits in a multi-agent setup, whereas exocentric cues notably increased team performance. Hierarchically structured teams resulted in fewer errors and improved efficiency during wayfinding tasks. Cognitive analysis revealed the importance of optimizing collaborative strategies to manage the mental demands of SAR missions instead of focusing on optimizing individuals. These findings contribute to understanding AR interface design’s complex role in multi-agent SAR support, aiming to improve AR system designs for SAR scenarios.

Psychiatric Mental Health Nurse Practitioner Job and Patient Outcomes: A Scoping Review

Psychiatric–mental health nurse practitioners (PMHNPs) offer a solution to the shortage of mental health care providers in a time of increased mental health demand. However, little is known about their job and patient outcomes. This scoping review aimed to explore PMHNP job outcomes, including satisfaction, burnout, and quality of work life, and patient mental health outcomes of PMHNP-delivered care. Twenty-four articles met the inclusion criteria and were published from January 2002 through October 2023. The existing research suggests that PMHNP-delivered care results in positive patient mental health outcomes for a variety of mental health conditions. For job outcomes, further research is warranted.

Quantifying the effects of training in lung transplantation: Lessons from NASA

IntroductionSequential lung transplantation is a complex procedure. The traditional training model continues to centre around operative experience with progressively increasing delegation of stages of the procedure. However, little evidence exists on the effects this has on surgical trainers. The NASA-TLX is a subjective, multi-dimensional assessment tool that rates perceived workload. We sought to employ this as a means of assessing the impact that training in lung transplantation has on trainers. MethodsWe prospectively collected the NASA-TLX data for 60 patients undergoing bilateral sequential lung transplantation. In 30 cases the operation was performed entirely by the senior surgeon (SS) who implanted both lungs. In 30 operations the senior surgeon implanted the right lung (SSR) and supervised a trainee implanting the left lung (TL). ResultsThe overall weighted rating was significantly lower for the surgeon undertaking the case themselves rather than training (p <0.001). Cases were comparable in terms of case type, donor ischaemic time and peri-operative characteristics. Mental and temporal demand were greater throughout training cases (p<0.001, p<0.05). There was less effect on frustration, physical demand and effort. Perceived performance showed no significant difference between the groups. ConclusionThe NASA task load index can be used to inform the effects of training lung transplantation on trainers. Training leads to greater mental and temporal demands with less effect on other factors. Crucially, there was no significant difference in perceived performance. As the specialty continues to be confronted with diverse challenges, this study should give confidence to those training the transplant surgeons of the future, as well as providing them with a mechanism to reflect on their own training performance.

Disentangling effort from probability of success: Temporal dynamics of frontal midline theta in effort-based reward processing

The ability to weigh a reward against the effort required to acquire it is critical for decision-making. However, extant experimental paradigms oftentimes confound increased effort demand with decreased reward probability, thereby obscuring neural correlates underlying these cognitive processes. To resolve this issue, we designed novel tasks that disentangled probability of success – and therefore reward probability – from effort demand. In Experiment 1, reward magnitude and effort demand were varied while reward probability was kept constant. In Experiment 2, effort demand and reward probability were varied while reward magnitude remained fixed. Electroencephalogram (EEG) data was recorded to explore how frontal midline theta (FMT; an electrophysiological index of mPFC function) and component P3 (an index of incentive salience) respond to effort demand, and reward magnitude and probability. We found no evidence that FMT tracked effort demands or net value during cue evaluation. At feedback, however, FMT power was enhanced for high compared to low effort trials, but not modulated by reward magnitude or probability. Conversely, P3 was sensitive to reward magnitude and probability at both cue and feedback phases and only integrated expended effort costs at feedback, such that P3 amplitudes continued to scale with reward magnitude and probability but were also increased for high compared to low effort reward feedback. These findings suggest that, when likelihood of success is equal, FMT power does not track net value of prospective effort-based rewards. Instead, expended cognitive effort potentiates FMT power and enhances the saliency of rewards at feedback. Significance statementThe way the brain weighs rewards against the effort required to achieve them is critical for understanding motivational disorders. Current paradigms confound increased effort demand with decreased reward probability, making it difficult to disentangle neural activity associated with effort costs from those associated with reward likelihood. Here, we explored the temporal dynamics of effort-based reward (via frontal midline theta (FMT) and component P3) while participants underwent a novel paradigm that kept probability of reward constant between mental effort demand conditions. Our findings suggest that the FMT does not track net value and that expended effort enhances, instead of attenuates, the saliency of rewards.

Beban Kerja Mental dan Kinerja Perawat Pelaksana Saat Pandemi Covid-19

&lt;p&gt;&lt;strong&gt;&lt;em&gt;Background&lt;/em&gt;&lt;/strong&gt;&lt;em&gt;: The COVID-19 pandemic caused an increase in the need for health services and health workers, especially nurses. As a consequence, nurses received heavy pressure and demand to be able to maintain and improve performance in an effort to reduce the spread of COVID-19. Apart from that, high demands from society created a mental workload for nurses. The aim of this study was to determine the relationship between mental workload and the performance of implementing nurses during the COVID-19 pandemic. &lt;strong&gt;Methods:&lt;/strong&gt; This quantitative research with a cross sectional design was conducted on 66 nurses who worked during the COVID-19 pandemic at Andalas University Hospital. Data collection was carried out in August-November 2021. The research instruments were performance questionnaires and NASA-TLX for mental workload. Data analysis used the chi square test. &lt;strong&gt;Results:&lt;/strong&gt; The research results showed that during the COVID-19 pandemic, nurses had moderate performance with the lowest performance sub-variable was implementation. Nurses had a heavy mental workload with the highest sub-variable was mental demands. &lt;strong&gt;Conclusion: &lt;/strong&gt;There was a relationship between mental workload and the performance of implementing nurses during the COVID-19 pandemic (p value = 0.000). It is hoped that Andalas University Hospital will pay more attention to mental workload, especially the mental demands of treating patients during the COVID-19 pandemic.&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Keywords: &lt;/strong&gt;&lt;em&gt;Mental Workload, Performance, COVID-19&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;em&gt;&lt;br /&gt;&lt;/em&gt;&lt;/p&gt;

Work-Related Hazards and Perceived Confined-Space Health Risk : Understanding the Correlation with Mental Workload Among Farmers in Northern Thailand’s Shallow Wells

ABSTRACT Objectives This study examined factors related to perceived health risks in confined spaces (PCSHR) and their correlation with the mental workload among farmers managing agricultural wells in northern Thailand. Methods A cross-sectional, multi-stage sample of 356 farmers was selected from four rural districts’ agricultural areas. Data were collected through interviews conducted from August to December 2022, using a self-administered structured questionnaire. The five-part questionnaire gathered demographic data, information on experiences and operations in agricultural wells, knowledge of confined spaces, PCSHR, and the six-dimension NASA Task Load Index (TLX) mental workload. Linear regression and multi-variable analyses were used to investigate factors associated with PCSHR, while Pearson correlations tested the association between PCSHR and mental workload variables. Results Most farmers were male (92.4%), worked in wells to install pumping systems (81.7%) and maintain equipment (73.3%), averaging 3.80 times per year, with an average duration of 25.81 minutes. Physical symptoms reported included difficulty breathing (72.8%), feeling swelteringly hot (55.9%), and sweating excessively (27.8%), as well as accidents such as being struck by falling soil or objects (20.2%), and falling into the well while climbing down (14.9%). Farmers’ perceived risk scores were high when working while physically exhausted or unprepared and when assisting an unconscious worker without knowing the gas concentration. In addition, the maximal mental workload scores were mental demand and effort subscale. Factors significantly associated with PCSHR (adj.R 2 = 60.6%, p < .05) encompassed education higher than lower secondary level, current alcohol consumption, smaller well width, assisted operations, number of physical symptoms experienced, absence of environmental accidents, and confined space knowledge, while increased PCSHR was positively associated with mental workload (Overall r = 0.711, p < .01). Conclusion Comprehensive education about potential hazards can improve farmers’ risk perception, potentially reducing mental workload and preventing fatal accidents. Field studies are recommended to develop community-specific work protocols and accurate measuring instruments suitable for rural settings are needed.

The LGBTQ+ Employee Mental Load Dilemma: Captive Identity and Adaptive Responses

Conceptualizations of mental load argue that marginalized employees may experience heightened mental load demands in the workplace (Sanders, 1979). Using the theories of facework, frontstage, and backstage performance (Goffman, 1978), we examine how workplace interactions may constrain or enable the performance of an LGBTQ+ identity in the workplace. We interviewed 35 U.S.-based LGBTQ+ employees to understand how mental load pressures shape identity presentation choices. Data were thematically analyzed using an iterative process based on principles of grounded theory. Two themes emerged: the Captive, or negative face threats, that LGBTQ+ employees described (including subthemes of professionalism and feelings of inescapability) and Adaptive strategies promoting negative face (including subthemes of making choices where possible, identity artifacts selections, and use of strategic ambiguity). Both captive and adaptive aspects of facework are considered for potential impact on increasing employee mental load.

Smoking Prevalence and its Association with Work-Related Factors in an Electricity and Gas Company

IntroductionIn the workplace, a smoke-free environment is crucial to guaranteeing the health of workers and those around them. Understanding the relationship between smoking and work is a prerequisite for implementing effective tobacco control measures.Objectives To assess the prevalence of smoking in an electricity and gas company in Sfax and to determine the relationship between workers’ nicotine dependence and perceived workload.MethodsWe conducted a cross-sectional survey evaluating the smoking behavior of 100 employees of an electricity and gas company. The survey was carried out from July to December 2022 using a two-part questionnaire. The first part was completed by the participants, and the second was administered by the interviewer. Nicotine dependence was assessed using the Fagerström test, while perceived workload was evaluated using the raw NASA-TLX questionnaire.Results Our study population consisted of 82 male participants. Active smoking was reported by 45.1% of participants. Among smokers, 40.5% had moderate to high nicotine dependence as assessed by the Fagerström test. According to the raw NASA-TLX questionnaire, the mean scores for mental, physical, and temporal demands were 88.8±13.5, 63.6±24.7, and 59.1±28.4, respectively. The mean scores for effort, performance, and frustration were 83.8±14, 85.4±13.1, and 34.5±28.1, respectively. Bivariate analysis indicated an inverse correlation between nicotine dependence and physical demands at work. However, a significant positive correlation was found between nicotine dependence and frustration at work.ConclusionsSmoking among electricity and gas company workers is a prevalent issue, highlighting the urgent need for smoking cessation interventions. The association of smoking with perceived workload underscores the importance of preventive measures to reduce work-related stress.Disclosure of InterestNone Declared

Low back pain and perceived psychological workload among electricians

IntroductionLow back pain (LBP) is a serious threat to electricians. It is well known that LBP is associated with physical strain. But the impact of psychological workload on the occurrence of LBP needs further investigation.ObjectivesThis study aimed to assess the link between LBP and perceived psychological workload among electricians.MethodsThe study was conducted with a sample of workers from a Tunisian Electricity society. Data were gathered between January-June 2022 using a self-administered questionnaire including socio-professional characteristics and the Nordic musculoskeletal questionnaire during the last 12 months and the last 7 days. To assess the perceived workload, we used the National Aeronautics and Space Administration Task Load Index (NASA-TLX). In this study, we evaluated raw NASA-TLX scores.Results Our study included 68 male electricians. The mean age was 39.2 ± 10.3 years. The average job tenure was 16± 11.4 years. According to the Nordic musculoskeletal questionnaire, 32.4% of participants reported low back pain during the last 12 months. Thirty participants (19.1%) had low back pain during the last 7 days. The mean score of mental demand, physical demand, performance, effort, frustration level and temporal demand were respectively 88.2±14.3, 61.1±24, 84.8±13.3, 82.6±14.5, 35.8±29.2 and 60.4±28.8. The frustration level was associated with the presence of LBP during the last 12 months and the last 7 days (p&lt;0.05).Conclusions From the results of this study, we conclude that LBP was associated with the perceived psychological workload. Hence, the prevention of LBP should go through the improvement of work conditions to enhance the mental health of the electricians.Disclosure of InterestNone Declared
