In 2019, two standardised holographic patients viewed through a mixed-reality (MR) HoloLens headset were used in a structured learning activity to develop clinical reasoning skills among second-year nursing students (N=99, 94%). Quantitative results indicated that all students felt that being able to closely view holographic patients enhanced their learning experience. Qualitative results showed that the best feature of the MR technology was being able to clinically assess the patient in a safe facilitated environment. Further analysis revealed that students were at the ‘beginning’ or ‘developing’ skill level of the vpLCJR. These findings confirm that using standardized holographic patients offers a dynamic and effective experience for students and helps students to develop clinical reasoning and judgement skills. The technology also allows educators to determine a student’s development of clinical judgement skills and tailor learning experiences to further develop these skills.
