Case study of virtual reality sepsis management- instructional design and ITEM outcomes.

This case study focuses on the instructional design and outcomes of a virtual reality (VR) application for sepsis management in healthcare education. The instructional design of the VR sepsis application follows five principles adapted from Merrill's instructional design theory and Bloom's taxonomy. The VR simulation is structured to provide a coherent and realistic experience, with instructional materials and feedback incorporated to guide and support the learners. A pilot study was conducted with medical students on clinical placement. Participants experienced the VR sepsis simulation and completed a questionnaire using the Immersive Technology Evaluation Measure (ITEM) to assess their immersion, intrinsic motivation, cognitive load, system usability, and debrief feedback. Descriptive analysis of the data showed median scores indicating high immersion and presence, intrinsic motivation, and perceived learning. However, participants reported a moderately high cognitive load. Comparison with a neutral response to ITEM suggested that users had a significantly higher user experience (p < 0.05) in all domains. This case study highlights the potential of VR in healthcare education and its application in sepsis management. The findings suggest that the instructional design principles used in the VR application can effectively engage learners and provide a realistic learning experience. Further research and evaluation are necessary to assess the impact of VR on learning outcomes and its integration into healthcare education settings.

The Removal of Airborne Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and Other Microbial Bioaerosols by Air Filtration on Coronavirus Disease 2019 (COVID-19) Surge Units.

Airborne severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was detected in a coronavirus disease 19 (COVID-19) ward before activation of HEPA-air filtration but not during filter operation; SARS-CoV-2 was again detected following filter deactivation. Airborne SARS-CoV-2 was infrequently detected in a COVID-19 intensive care unit. Bioaerosol was also effectively filtered.
