Increasingly sophisticated robots mimic various conditions and enable medical students to apply the tools of clinical practice. Nevertheless, their cost has been a subject of criticism.
Manage Email AlertsDoctors treated a robot in Trieste, Italy. Is this a scene straight out of a science fiction movie? Not this time. The robot is HAL s5301, one of the most advanced patient simulators in existence.
Various studies have indicated that simulators are beneficial, especially for students, in honing individual and team skills in all sorts of specialties. A 1987 study showed that the Harvey simulator improved the diagnostic skills of medical students in some areas.
Can similar results be achieved without spending so much money? Maybe. One aspect still to be clarified in scientific literature is whether the use of simulators translates into better patient outcomes. The few systematic reviews available find no statistically significant advantage of training with simulators, compared with traditional teaching, when it comes to patient outcomes in endoscopy or in the surgical field.
Conversely, at least two studies, one from 2021 and the other 2022, showed that students were more comfortable and found it more informative to practice with human-simulated patients than with robots, which were perceived as being less realistic. Conversely, a mannequin runs the risk of being too "honest" in its imitation of symptoms, without the ambiguities doctors are faced with in real life. The risk of "mistraining" also results from the imperfect anatomic accuracy of mannequin simulators, as has been shown in various studies.
