“…Digital twins offer particular promise in critical care, where large quantities of data are continuously available, and the risk to patient safety posed by medical interventions is often significant (7,8). The benefits of a digital twin patient model to inform clinical decisionmaking in critical illness have been previously proposed (9)(10)(11)(12). Digital twins could also be adapted for critical care education, allowing learners to simulate the effects of various interventions and explore their potential outcomes in a controlled, virtual environment without negative patient impacts (13,14).…”

BackgroundDigital twins are computerized patient replicas that allow clinical interventions testing in silico to minimize preventable patient harm. Our group has developed a novel application software utilizing a digital twin patient model based on electronic health record (EHR) variables to simulate clinical trajectories during the initial 6 h of critical illness. This study aimed to assess the usability, workload, and acceptance of the digital twin application as an educational tool in critical care.MethodsA mixed methods study was conducted during seven user testing sessions of the digital twin application with thirty-five first-year internal medicine residents. Qualitative data were collected using a think-aloud and semi-structured interview format, while quantitative measurements included the System Usability Scale (SUS), NASA Task Load Index (NASA-TLX), and a short survey.ResultsMedian SUS scores and NASA-TLX were 70 (IQR 62.5–82.5) and 29.2 (IQR 22.5–34.2), consistent with good software usability and low to moderate workload, respectively. Residents expressed interest in using the digital twin application for ICU rotations and identified five themes for software improvement: clinical fidelity, interface organization, learning experience, serious gaming, and implementation strategies.ConclusionA digital twin application based on EHR clinical variables showed good usability and high acceptance for critical care education.
