Researchers at Johns Hopkins created an explainable AI tool to coach medical students while they practice suturing. The system learned from videos of expert surgeons and from tracked hand movements as surgeons closed incisions.
The AI rates a student’s technique and sends a personalized text message after practice. The message compares a student’s movements to experts and points to changes to improve. In a small study, 12 students were randomly assigned to two methods: one group got immediate AI feedback, the other group watched recorded surgeon videos and practiced again. Students with prior surgical skill improved faster with AI, while beginners showed less benefit. The team plans to make the model easier to use and more available, possibly for home practice with a suturing kit and smartphone.
