The students interviewed in this study perceive that the use of ISTs in medical education has both positive and negative impacts. From their accounts, it is not easy to draw a clear boundary between the factors that favor learning and skill development and those that could hinder them, as students' assessments are influenced by nuances, contradictions, and ambivalences that require a more in-depth analysis. Nevertheless, the interviews show a general accepting attitude of these technologies, which are seen as part of the inevitable development of the medical profession and scientific technical progress. Moreover, participants agree in identifying certain benefits associated with its use, plus some limitations and challenges. The primary findings of the study are presented below.
Learning, Practicing, and Trusting: The Positive Impact of ISTs on Medical Education
One of the most salient aspects of students' accounts is the positive impact of ISTs on the development of practical and clinical skills. These technologies give them the opportunity to practice techniques and procedures in a safe and controlled environment, allowing users to repeat them several times without any risks for patients. This possibility boosts their confidence from early education stages, and helps them feel more comfortable and perfect the skills they are acquiring. According to accounts, this is especially relevant when performing invasive procedures, where the possibility of pre-training reduces anxiety and improves accuracy in real clinical scenarios.
Additionally, ISTs offer the opportunity to explore rare or difficult-to-access pathologies during clinical rotations. As mentioned by one of the students, "using these technologies is beneficial because it is not always easy to find patients with the conditions we need to see" (E1). Thus, simulation enables access to complex or unusual clinical scenarios, providing learning opportunities that would otherwise be limited. In this regard, another student said, "In real life, I have never seen, for example, papilledema in a fundus in any patient, but I could treat it in the simulation" (E1).
The students interviewed also agreed that using simulators boosts learning in areas such as clinical semiology, where repeated exposure is essential to acquire diagnostic skills. A student made the following remark in relation to auscultation: "If I had been told that this is what a diastolic mitral murmur sounds like in the clinic, I would probably have heard it only once, and then, I would have had trouble remembering it. However, with the simulators and features provided by the simulation labs, you can learn more about those experiences" (E2). Simulation also allows students to better prepare for their clinical rotations. Another account reflects this usefulness in practical skills training: "Also, channeling has been quite useful to me for rotation before it comes my way" (E5).
Moreover, interactive digital tools complement the teaching of anatomy by facilitating the understanding of complex structures through visualization in different formats. Students highlight its usefulness for memorizing and analyzing anatomical structures through virtual screens and 3D devices, allowing them to explore the human body from different perspectives, in a more intuitive and didactic manner. A student highlighted the value of these resources as follows: "In the amphitheater, there is a platform where you can select what you want to see of body anatomy. It's a giant screen where you can see muscles, bones, arteries, etc., and teachers use it to help us understand better" (E3).
In addition to the development of practical and clinical skills, students mention that ISTs provide a controlled environment where they can make mistakes, get feedback, and learn from mistakes without any fatal consequences to patients or any legal risks. As a student mentioned, "we have a controlled environment where we can, fortunately, make a mistake and be corrected without any legal consequences or more serious results" (E5).
The difference between practicing in a simulated environment and directly facing a real patient is significant for several of the interviewees. One student put it this way: "You do the procedures, one, two, three, four, five, six steps, done, you memorize them. But I think that when you memorize them and then move on to a real patient, who is flesh and blood and who feels, you are already under much more pressure and can make a mistake. In turn, when practicing with a mannequin, there is no error that could be life-damaging" (E7).
By practicing in a simulated environment, students become familiar with clinical scenarios and are better prepared to deal with the uncertainty of medical care. This reduces the stress of interacting with real patients, boosting their confidence as well. It also allows to let go of the fear and insecurity that can arise in sensitive procedures, as mentioned in another account: "We learn primary health care of pregnant women and carry out a gynecology practice. I feel that doing that on the mannequin is less traumatic than doing it with a patient" (E7).
One of the aspects most valued by students in the use of ISTs is the possibility of receiving immediate feedback from teachers, something that is usually more difficult to achieve in real clinical scenarios. This allows them to correct mistakes in a timely manner and turns the error into a learning opportunity, thereby strengthening the development of practical and clinical skills.
When Technology Is Not Enough: Empathy, Realism, and Equitable Access
Along with the advantages identified, the accounts also show some difficulties related to the use of ISTs in medical education. These limitations are associated with the impairment of communication skills and empathy generation, oversimplification of clinical reality, inequalities and difficulties in accessing technologies, and technical and digital literacy problems.
One of the most frequent concerns expressed by the students interviewed is that although ISTs boost certain technical skills, they fail to reproduce the emotional and interpersonal complexity of the doctor–patient relationship. This difficulty is regarded as an obstacle in the development of communication skills necessary to understand the patient and address the situation in a comprehensive and problem-solving manner. One of the students interviewed summed it up as follows: "Clearly, these technologies do not allow us, as physicians, to develop empathy or to be more humans with patients because, at the end of the day, we practice with a machine, a robot that cannot feel, does not communicate, or have feelings" (E5).
Along the same lines, several students agree that clinical rotations are the most appropriate learning space to develop social and communication skills, which are key for patient interaction. As one student explained: "I think [technology] does not help to improve communication with patients at all, nor does it help with empathy; I even think it is the opposite. The clinic has really helped me a lot to develop my communication skills and to adapt very well to patients, in the way I speak and the way I express myself" (E8). For the interviewees, recognizing these limitations does not mean denying the advantages of ISTs but emphasizing that their use should be a complement and not a substitute for learning in real clinical settings, which involve direct contact with people and with the different stakeholders in the healthcare system such as physicians, the nursing staff, residents, interns, and family members.
Another difficulty mentioned is that ISTs tend to simplify clinical reality. Although students noted that their use prepares them to perform certain procedures with greater skills, such as auscultation and simple surgical interventions, they are not always adapted to the diversity of situations faced by physicians in daily practice because they overlook significant differences in human anatomy. Regarding the use of CardioLink, one of the students interviewed commented: "The practice is with a slim man, which makes the use of the stethoscope easier, but in women, for example, it does not resemble the large breasts of many of them. This is something that can affect us when it comes to locating the stethoscope and listening correctly" (E1).
These technological resources are thought to omit some essential aspects of clinical interaction, such as discomfort management, body posture, communication about the procedure or the need to adapt to patients' reactions. In the interview, a student said, "We are taught to listen here or access the eye this way, but we need further instruction on how to do it with a real patient, explaining what we are going to do, what may bother them, and how to face them" (E1). Thus, students' perception is that ISTs can generate an idealized or incomplete image of medical practice, thereby reducing exposure to practices and situations that only emerge in real clinical contexts.
An example of this is the difficulty ISTs have in representing situations of high emotional stress or urgency, where students must make quick decisions, sometimes under pressure. In this regard, one student highlighted, "When you have an emergency in real life, if someone is bleeding to death, you run, you do one thing, then another, and all at the same time. But in this [simulated] activity, you cannot do everything at once, without conducting each step separately. I think this was negative, because you have to learn to do those things simultaneously, not in isolation" (E3).
Students also perceive that the use of ISTs in medical education may be mediated by gaps in access. Specifically, they point out the difference between low- and middle-income countries and high-income ones, which translates into a delay in innovation implementation and equipment update, generally developed in more technologically advanced contexts. This inequality is also observed at the local level, as students compare their experience with that of other institutions that, in their opinion, have greater resources. Thus, they express concern about the impact that these differences may have on their educational process.
The interviewees' expectations regarding the use of ISTs are also mediated by a return-on-investment logic associated with the costs of higher education. Students value their academic experience in terms of the services offered by the university and are especially sensitive to infrastructure and equipment inequalities. Comparisons with other institutions which, from their viewpoint, have better conditions, reinforce the demand for constant updating of training facilities. In some cases, they even suggest the need for laboratories equipped with advanced technologies.
These gaps can also be seen in equipment availability, which, as per interviewees, is conditioned by the time and space allocated by the university for internships. As one student said, "As there are so many of us, time is limited. They make us practice in order, but we can't take all the time" (E1). In view of this situation, they identify the need to organize and streamline the use of these technologies, allowing their use at times other than those initially established in the micro-curriculum.
Finally, other limitations mentioned include technical failures that interrupt practices and cause students to lose time. Sometimes, teachers cannot solve these problems, thereby requiring the assistance of specialized technical personnel. Deteriorated equipment due to wear and tear or equipment unavailable due to maintenance or with recurrent failures is also mentioned.
