The COVID-19 crisis demanded that all educational activities should be performed virtually to follow social distancing guidelines. Therefore, there was a need to perform a research study to assess the effects of external factors on the perceived usefulness, ease of use of e-learning, and the further effect of these perceptions on attitude and intent to use e-learning by using the technology acceptance model (TAM) among academicians at higher education institutions in the Kingdom of Saudi Arabia. Methods: A cross-sectional study was conducted, and data were collected from 263 academicians across Saudi Arabia through an online survey questionnaire using a non-probability purposive sampling technique and analyzed and tested using the SPSS and Smart PLS software. Results: This study found that self-efficacy was positively associated with perceived usefulness at β = 0.143 and p < 0.05, but it had no association with perceived ease of use at β = 0.057 at p > 0.05. System accessibility had a significant and positive relationship with perceived usefulness and perceived ease of use at β = 0.283, β = 0.247, and p < 0.01, respectively. Self-efficacy had a positive effect on perceived usefulness, whereas the subjective norm had no relationship with perceived usefulness and perceived ease of use at β = −0.065 and β = −0.012 at p > 0.05, respectively. Perceived ease of use and perceived usefulness were positively related to attitude towards use, which has a significant influence on intention to use e-learning. Conclusion: Perceived ease of application is the most significant factor (β = 0.556) in developing the attitude among academicians to practice e-learning, followed by perceived usefulness (β = 0.262). Moreover, it can be concluded that system accessibility has a stronger influence on developing perception among academicians about the expediency and ease of application of e-learning than self-efficacy.

“…To address these limitations, we are currently collaborating with an engineering company to develop an updated version of LICENSE that incorporates these additional sources of fluid input and output. LICENSE needs further testing to obtain approval and certification by the CE mark, which is mandatory for medical devices marketed in The European Union and indicates compliance with health, safety and environmental standards [ 35 ].…”

BACKGROUND: Precise fluid balance monitoring is essential for patient treatment, as incorrect fluid balance can lead to disorders. OBJECTIVE: This study aimed to assess the accuracy of the digital technology LICENSE (LIquid balanCE moNitoring SystEm) for fluid balance charting and compare it to the standard method (SM) to determine its usability in clinical practice. METHODS: This prospective study included 20 patients. The results from LICENSE were compared to those from SM and a reference measurement (manual weight of fluids, RM). Three LICENSE devices were used for urine output, intravenous fluids, and oral fluid intake. The accuracy of methods was evaluated using Bland Altman plots. RESULTS: The mean difference between LICENSE and RM was less than 2 millilitres (p= 0.031 and p= 0.047), whereas the mean difference between SM and RM was 6.6 ml and 10.8 ml (p< 0.0001). The range between the upper and lower limits of agreement was between 16.4 and 27.8 ml for LICENSE measurements and 25.2 and 52 ml for SM. CONCLUSION: LICENSE is comparable to or more accurate than the standard method for fluid balance monitoring. The use of LICENSE may improve the accuracy of fluid balance measurements. Further research is needed to evaluate its feasibility in daily clinical practice.

“…By prototyping and testing early and often, designers can identify potential issues, validate assumptions, and make informed design decisions based on empirical evidence, rather than relying on intuition or guesswork. This evidence-based approach reduces the likelihood of costly errors or rework later in the development process, ultimately saving time, resources, and effort (Badnjevic, 2023). For example, usability testing with clinicians in simulated clinical environments can help identify workflow bottlenecks, usability issues, and safety concerns early in the development process, enabling designers to iterate on the design to address these issues before finalizing the product.…”

User Experience (UX) Design in Medical Products is pivotal in enhancing patient outcomes, satisfaction, and adherence to treatment regimens. This abstract delves into the theoretical underpinnings and best practices that underscore effective UX design within the medical domain. Grounded in human-centered design principles, this approach emphasizes understanding user needs, preferences, and limitations to develop inclusive, accessible, and intuitive interfaces. Integrating insights from behavioral psychology, UX designers leverage techniques such as persuasive design to promote healthy behaviors and facilitate adherence to medical protocols. Moreover, compliance with regulatory standards is paramount, necessitating a nuanced understanding of medical regulations and standards to ensure product safety and efficacy. Usability testing emerges as a crucial step, facilitating iterative improvements based on user feedback and ensuring that medical products are intuitive, error-resistant, and conducive to safe user interactions. Beyond functionality, considerations of data privacy and security are paramount, requiring UX designers to implement robust measures to safeguard patient confidentiality while maintaining seamless user experiences. Communication between patients and healthcare providers is also a focal point, with UX strategies aimed at enhancing information exchange, fostering trust, and facilitating informed decision-making. Additionally, optimizing workflow efficiency through streamlined task sequences and leveraging emerging technologies such as artificial intelligence and augmented reality further enhances the user experience in medical contexts. Through continual iteration and refinement, UX design in medical products strives to deliver compassionate, user-centric solutions that meet the diverse needs of patients and healthcare professionals alike, ultimately driving improved healthcare delivery and patient outcomes.
