Implementing change in complex healthcare systems is inherently difficult, with most change initiatives failing. Human Factors/Ergonomics can support change processes through better understanding of the current system and designing and implementing new improved ways of working. One in four patients have a documented antibiotic allergy. Inaccurate and unverified antibiotic allergy labels have a negative impact on patient outcomes. The authors have been involved in the successful introduction of a new approach to allergy de-labelling in the intensive care unit. The primary objective of this study was to outline how this change was supported by applying Human Factors/Ergonomics to the change process. The Cube socio-technical systems analysis was used to understand and support this complex change across four domains of culture, system functioning, action and sensemaking and across a change cycle of understanding the current ‘as is’ problem; co-designing the ‘to be’ solution; planning and preparing to change; implementing and embedding the change. Over the course of the study 85 patients with either a reported non-immune or low risk antibiotic allergy were successfully de-labelled. This study exemplifies Human Factors/Ergonomics in action and has shown that taking a structured approach to change, that aims to understand and alter different system components, can achieve results.

This study examined the impact of sex and lacing pattern on foot skin temperature (Tsk) and comfort during running. Twenty-four recreational runners participated in two treadmill trials involving cross-lacing and heel-lock lacing. Tsk and comfort were measured before and after 20 min of running at 10 km/h. Results revealed higher post-exercise Tsk with cross-lacing compared to heel-lock lacing (p = 0.003). Females had lower pre-exercise Tsk but higher post-exercise Tsk than males (p < 0.001). Heel-lock lacing was perceived as more comfortable (p < 0.05), and females reported higher heart rates and perceived exertion (p < 0.001). The mechanical work of running is crucial for the impact of lacing patterns on Tsk. Increased Tsk with cross-lacing negatively influences comfort, suggesting that lacing patterns can affect foot thermoregulation and subjective experience during running.

Recent technological transitions present in the manufacturing sector are transforming the way operators work, greatly impacting their mental workload and presenting new challenges for the cognitive ergonomics field. In an effort to design and implement human-centered management strategies, it is increasingly necessary to effectively explore and evaluate the various aspects related to mental workload. Despite the maturity of the field, in the existing literature a consensus on defining mental workload remains elusive. To bridge this gap, this paper introduces a comprehensive and holistic definition, drawing inspiration from the ISO 10075 standard. This novel taxonomic framework distinguishes various constructs related to mental workload, clarifying their causes and the consequences they induce. Additionally, an extensive literature analysis was conducted to develop a taxonomy of mental workload assessment tools, outlining their operational principles along with their strengths and weaknesses. This taxonomy can be used as a pragmatic guide for selecting appropriate tools based on specific contexts. Moreover, the existing literature was extensively investigated to ascertain the nature of the correlation—whether positive or negative—between the metrics of these tools and the range of the effects of mental workload fluctuations. This methodological approach addresses the common issue of misinterpreting results from mental workload measurements.
In essence, the research seeks to enrich the understanding of mental workload concepts and offers a critical evaluation of its measurement tools. The findings are intended to assist practitioners in the informed selection of measurement tools and to refine data interpretation, thereby facilitating better management of mental workload in manufacturing environments.

This study evaluated COVID-19 home test kit usability focusing on effectiveness, efficiency, and satisfaction across diverse users and environments. Using a mixed-methods approach—including use analysis, user experience survey (n = 1045), and usability testing (n = 80) in South Korea—we identified a significant gap between high user satisfaction and actual performance. Despite positive satisfaction metrics (SUS score: 74.37 %), we observed concerns regarding effectiveness (29.9 % error rate) and efficiency (20 % unnecessary second kit use, 57.5 % repeated instruction references). The usability of home test kits was significantly influenced by age, education level, and prior experience, while the testing environment showed a less pronounced but still observable effect. Based on our findings, we propose design improvements to instructions, physical components of test kits, and instruction presentation. This research highlights the importance of usability in designing test kits that accommodate diverse populations, potentially improving public health outcomes and pandemic preparedness.

Background
Despite the transformative potential of health applications (apps) to improve the general public's health and healthcare knowledge, their acceptance remains a barrier to success. Although research on health app acceptance has expanded, most studies have focused on classical factors, such as those in the technology acceptance model (TAM), giving less attention to health-app-specific factors, such as technological characteristics and operational details.
Objectives
To expand our knowledge of the factors influencing health app acceptance, particularly among the general public, this study aimed to (i) develop and test a model of acceptance (measured by intention to use) that incorporates TAM constructs and health-app-specific factors and (ii) examine the moderating effects of selected socio-demographic characteristics on intention to use.
Methods
We formulated an acceptance model by expanding the TAM to include nine additional constructs and tested it using a cross-sectional survey of 600 adults from the general public, stratified by age, gender, and district of residence. Partial least squares structural equation modeling was applied to test the structural model. Multigroup analyses examined whether age, gender, education level, and household income moderated the relationships between model factors and acceptance.
Results
The model accounted for 55 % of the variance in acceptance, which was positively influenced by perceived usefulness, mHealth literacy, smartphone screen size, and healthcare providers’ attitudes and negatively affected by smartphone memory consumption. Perceived ease of use, favorable features, and quality of information explained 58 % of the variance in perceived usefulness. Regarding moderation, older individuals showed less concern about perceived usefulness, whereas men and individuals with higher education levels exhibited less concern about smartphone screen size.
Conclusion
Our acceptance model showed strong empirical fit and the potential to support health app development and deployment. To achieve acceptance among the general public, app developers should enhance app usability, ensure high-quality information, include desirable app features, and meet user needs. Usability testing and stakeholder-centered design approaches are essential to achieve these goals.

Unintended positional drift (UPD) is an important factor during virtual reality (VR) use, as it may contribute to safety risks diminishing user experience, potentially hindering the broader adoption of VR technology. This study investigated the effects of locomotion and steering methods on UPD through a 2 × 2 within-subject experiment. We selected two locomotion methods (joystick and teleportation) and two steering methods (controller-based and physical-based). Thirty-two participants (16 males and 16 females; mean age = 22.65 years, SD = 2.06) completed a VR task under all four conditions. Joystick locomotion resulted in significantly greater movement variance (MV) compared to teleportation, leading to higher Y-axis MV per minute (MVY: p = .043) and significantly longer task completion time (TCT: p = .002). For subjective measures, joystick locomotion also produced higher body movement cognition (BMC) (p = .001) and greater postural stability questionnaire scores (PSQ) (p < .001). Compared to controller steering, physical steering resulted in significantly greater total movement (TM) and MV, including TMX, TMY, MVX, and MVY (all p < .001). Physical steering also led to higher BMC (p < .001), greater PSQ scores (p < .001), and increased virtual embodiment questionnaire (VEQ) scores—specifically for ownership (p = .002) and agency (p < .001). These findings suggest that the choice of locomotion and steering methods in VR should be carefully tailored to the intended application, with designers considering the trade-offs associated with UPD.
意外位置漂移（UPD）是虚拟现实（VR）使用过程中的一个重要因素，因为它可能会带来安全风险，降低用户体验，潜在地阻碍VR技术的广泛采用。本研究通过2 × 2受试者实验研究了运动和转向方法对UPD的影响。我们选择了两种移动方法（游戏邦注：即操纵杆和传送）和两种转向方法（基于控制器和基于物理）。32名参与者（16名男性和16名女性，平均年龄= 22.65岁，SD = 2.06）在所有四种条件下完成了VR任务。操纵杆移动导致的移动方差（MV）显著高于隐形移动，导致更高的y轴MV /分钟（MVY: p = 0.043）和更长的任务完成时间（TCT: p = 0.002）。对于主观测量，操纵杆运动也产生更高的身体运动认知（BMC） （p = .001）和更高的姿势稳定性问卷得分（PSQ） （p = .001）

Patient lifting can expose health care workers to musculoskeletal disorder (MSD) risk factors. Portable lift assist devices may reduce exposure during lifting, however limited evidence on user feedback and efficacy is available to inform purchase decisions. Therefore, we tested the efficacy of two portable lift assist devices relative to a manual lift when lifting an individual from the floor. Participants lifted an actor from the floor using a manual technique and by using two lift assist devices, either an inflatable bladder or a mechanical device. Ratings of perceived exertion demonstrated that the lift assist devices decreased or maintained perceived exertion relative to the manual lift. Semi-structured interviews provided context where perceived benefits of the devices (i.e., decreased exertion and MSD risk) outweighed barriers (i.e., added time to call). The results of this study can inform stakeholders making decisions about lift assist devices purchases.

A major advantage of autonomous vehicles (AVs) is the passengers’ ability to perform non-driving related tasks (NDRTs) while being driven. Among these NDRTs, social interaction with other passengers is considered to be particularly valuable. Seating layouts featuring rotatable front seats will enable a new level of social interaction during autonomous car journeys. However, being seated against the direction of travel is not very popular. Fear of motion sickness is one of the main reasons for this reluctance, which is commonly explained by the inability to see the road ahead. This raises the question to what extent motion sickness in rearward facing passengers of autonomous vehicles is to be expected and to what degree this is caused by the inability to see through the windscreen. To answer this question, a field experiment in real traffic with N = 55 participants was conducted. Seating orientation and forward view were manipulated and their effects on motion sickness as well as related factors relevant to the acceptance of AVs were analyzed. Both a rearward seating orientation and a restricted forward view led to significantly increased motion sickness. The insights gained serve as a basis for the development of HMIs that improve the acceptance of rearward facing seating orientations in AVs.

Human movement relies on visual and proprioceptive inputs, and the movement can be hampered when either input provides limited or distorted information, as in robotic surgery, virtual reality, or spaceflight. This study examines how proprioception influences performance in aimed movement tasks under restricted and inverted visual conditions. An experiment with 24 participants showed slower movements and increased information processing demands with incompatible visual feedback. The difference was diminished when the proprioceptive variability was controlled through ANCOVA. The findings allude to the necessity of considering individual differences in proprioceptive ability when evaluating performance across different visual conditions. These results can help develop training protocols and design interfaces when visual and proprioception sensory feedback are incompatible. Also, continuous visual feedback of hand movement may not be necessary. Instead, a correctly sized visual window of the target is sufficient for aimed movement tasks. This result has practical implications, especially when optimizing VR renders.

This study examines how proprioception influences performance in aimed movement tasks under restricted and inverted visual conditions. An experiment with 24 participants showed slower movements and increased information processing demands with incompatible visual feedback. The difference was diminished when the proprioceptive variability was controlled through ANCOVA. The findings allude to the necessity of considering individual differences in proprioceptive ability when evaluating performance across different visual conditions. These results can help develop training protocols and design interfaces when visual and proprioception sensory feedback are incompatible. Also, continuous visual feedback of hand movement may not be necessary. Instead, a correctly sized visual window of the target is sufficient for aimed movement tasks.

This research was designed to examine the contribution of domain-specific cue utilization and self-reported experience to safety performance within the context of small Visual Line of Sight (VLOS) Remotely Piloted Aircraft (RPA) operations. The capacity to utilize and integrate domain-specific cues is potentially advantageous in operating aircraft where the range of sensory cues available is constrained. However, the impact of domain-specific cue utilization on safety performance has yet to be investigated in the context of RPA operations. Data were obtained from 48 remote pilots with a range of operational experience. The participants completed the VLOS RPA edition of EXPERTise 2.0, which provided an assessment of cue utilization. The participants also completed a survey of their experience of adverse RPA safety events. The results indicated that small VLOS RPA pilots with relatively higher levels of domain-specific cue utilization were less likely to be involved in adverse RPA safety events, independent of conventional and remote aviation flying experience. While higher levels of recent remote flying activity were advantageous for all remote pilots regardless of their level of cue utilization, higher levels of recency were associated with a disproportionate improvement in the safety performance of individuals with relatively lower levels of cue utilization. The outcomes have implications for both training and the assessment of pilot performance in RPA operations.
