Effect of multimodal comprehensive communication skills training with video analysis by artificial intelligence for physicians on acute geriatric care: a mixed-methods study

Objectives: To quantitatively analyse by artificial intelligence (AI) the communication skills of physicians in an acute care hospital for geriatric care following a multimodal comprehensive care communication skills training programme and to qualitatively explore the educational benefits of this training programme. Design: A convergent mixed-methods study, including an intervention trial with a quasi-experimental design, was conducted to quantitatively analyse the communication skills of physicians. Qualitative data were collected via physicians\u27 responses to an open-ended questionnaire administered after the training. Setting: An acute care hospital. Participants: A total of 23 physicians. Interventions: In a 4-week multimodal comprehensive care communication skills training programme, including video lectures and bedside instruction, from May to October 2021, all the participants examined a simulated patient in the same scenario before and after their training. These examinations were video recorded by an eye-tracking camera and two fixed cameras. Then, the videos were analysed for communication skills by AI. Main outcome measures: The primary outcomes were the physicians\u27 eye contact, verbal expression, physical touch and multimodal communication skills with a simulated patient. The secondary outcomes were the physicians\u27 empathy and burnout scores. Results: The proportion of the duration of the participants\u27 single and multimodal types of communication significantly increased (p\u3c 0.001). The mean empathy scores and the personal accomplishment burnout scores also significantly increased after training. We developed a learning cycle model based on the six categories that changed after training from the physicians\u27 perspective: multimodal comprehensive care communication skills training; increasing awareness of and sensitivity to changes to geriatric patients\u27 condition; changes in clinical management; professionalism; team building and personal accomplishments. Conclusions: Our study showed that multimodal comprehensive care communication skills training for physicians increased the proportions of time spent performing single and multimodal communication skills by video analysis through AI.
