Principal results
Given the increasing use of DHT in the practice of medicine, the current study intended to analyze the extent to which medical schools are equipping their students with digital health knowhow, preparing them to leverage such technologies in their practice. The current study relied on data from 60 top-ranked medical schools around the world. First, mission statements were investigated to analyze whether, or not, DHT and innovation are factored into the set directions of the universities and their medical schools. The results showed that only nine universities refer to technology in their mission statements, showing willingness to integrate technology as part of their curricula. The curricula of all the included medical programs were then investigated to identify how digital health technology are taught to their students. In total, only four medical schools appear, from their websites, to teach some elements of digital health. The majority of DHT teaching are delivered as part of innovation group projects rather than dedicated lectures, except for the University of Zurich. Though group projects allow students to apply the knowledge contextually, there is a risk that students only focus on one type of DHT. For instance, one cohort could work on chronic pain as a challenge for its innovation project, where they would explore the realm of digital therapeutics or VR, while another cohort could look at wearable technologies to help the population attain a better lifestyle. As a result, students very often do not have the chance to extensively cover the whole terrain of DHT.
The current study highlights several key findings. First, it reveals minimal alignment, in relation to the inclination to teach students technology and innovation, between the mission statements of the universities and their medical schools, and the content of the medical curricula. It is not uncommon for the top-ranked medical schools to refer to how they are equipping students with what is needed for the future of health care. Moreover, amongst the nine universities referring to technology as part of their mission statements (either that of the university or that of the medical school), none of them appear to deliver DHT as part of their medical curriculum, according to their websites. It is possible that medical schools have a DHT offering but this is not advertised on their website. Given the importance of DHT in health care, this observation in of itself is worth taking into account for medical school websites (re)design.
Second, the study highlights that the number of medical schools that teach DHT is critically low despite the recent surge of attention towards their deployment in practice. Today, wearable technologies such as activity trackers can collect continuous data to objectively understand patients’ quality of life [32], unlike traditional methods that rely on subjective self-reporting. Not only is that data relevant to monitor patients’ lifestyle, but also to create digital interventions to change patients’ behavior thereby improving their quality of life [33, 34]. However, many hospitals and clinics do not currently have access to such valuable data to diagnose and monitor patients. This may be due to lack of awareness about the utilization and true value of DHT. Similar comments can be made regarding other DHT, such as: VR, that constitutes an evidence-based treatment modality for reducing both acute and chronic pain [10, 11], as well as digital therapeutics that can complement or replace traditional pills, thereby decreasing potential side effects and improving comfort [35]. As such, the results of the current study reinforce the argument that the lack of integration of DHT in medical schools’ curricula represents a crucial missed opportunity with regards to improving the quality of care and preparing medical students for the future of medical practice. Otherwise, given the rapidly evolving technology, this quote will hold true: ‘the physicians of tomorrow are taught by the teachers of today using the curriculum of the past’ [36].
Upon reviewing the news section of the official websites of the included universities, two universities that publicly share that they are working on developing their DHT teaching offerings were identified. The Charité - Universitätsmedizin Berlin is piloting a new course that includes 22 units (lectures and group projects) covering diverse DHT content from augmented reality and VR, AI, mHealth, telehealth, and 3D printing. The course also includes clinical scenarios such as digital surgical training, value-based digital radiology, and personalized drug therapies in addition to innovation [37]. The University of Zurich is also working towards expanding its DHT offering by 2024 through incorporating into the respective program: programming and computational thinking, mobile health and smart devices, augmented reality and VR, and computer assisted medicine, as well as digital patient-physician communication. Beyond the information systematically collected and analyzed in the current study, there seems to be American universities that provide some digital health teaching to medical students but mostly through extra-curricular and elective classes [38].
It is worth reflecting on the potential successful factors of the integration of DHT teaching offerings in medical curricula and developing an understanding of what the medical schools that appear to teach DHT have in common. Apart from a positive, progressive mindset and the support from academic leads, the integration of DHT in medical curricula seems to require strong multidisciplinary collaborations. The Stanford Byers Center for Biodesign is a good example, in that regard. With the intention of bridging the gap pertaining to the absence of technology expertise in the medical school, it was decided early-on for a formal collaboration to be formed between the respective medical school and that of engineering. A few years after, as well, the business school joined with its expertise on commercialization. While clinicians can teach and explain the value of DHT, it is believed that engineers, such as: computer scientists, are needed to describe the components and the functionalities of DHT [39]. If medical schools would like their students to be enabled to identify when to deploy DHT and which clinical encounters can benefit from DHT, in-depth understanding of such technologies is required. For instance, why do some activity trackers have a green versus a red optical sensor? It would therefore help the basic or clinical medical sciences faculty to understand photoplethysmography. Moreover, it is important to ensure that DHT is carefully regulated and calibrated to maintain adequate levels of patient safety. This will also raise patient and physician confidence in DHT. All of which will feed into increasing the likelihood of integration of DHT teaching offerings in medical curricula.
Recent research on digital health [31] shows that the following technologies have the most impact on patient outcomes: mobile health, wearables, augmented reality, VR, AI, 3D printing, and drones. Table 4 is an example of a homegrown curriculum [31] which focuses on nurturing among medical studies competencies related to such technology, offered in Mohammed Bin Rashid University of Medicine and Health Sciences (MBRU) within Dubai Health in Dubai, United Arab Emirates.

Limitations and future direction
This study is characterized by several limitations. Although the selection of universities was performed systematically, it is restricted: high ranking universities may not necessarily be the most advanced in terms of digital health. There could be medical schools which are quite advanced in terms of integrating digital health into their respective curricula but are not top ranked. For instance, an elective course was offered as part of the medical curriculum at Semmelweis University, Budapest, Hungary to enable students in terms of digital literacy, teaching them a broad range of topics including the meaningful utilization of the Internet (within the medical profession), with a special emphasis on social media [40]. Another example is the abovementioned course on DHT and Innovation offered to all first-year medical students at MBRU within Dubai Health in Dubai, United Arab Emirates, through its innovation arm: MBRU Design Lab (Table 4) [31]. The MBRU Design Lab also offers medical students the opportunity to participate in hackathons and bootcamps, where they work with engineering and design students [41]. Due to the young age of the respective university, it currently does not appear as part of the THE ranking. Another example is the University of Bristol in the UK (which narrowly missed inclusion in the study due to ranking at the time of data collection) that designed a Masters dedicated to DHT [42]. The program notably includes classes covering health innovation, epidemiology, AI, computer programming, and data analytics. Moreover, although this study offered plenty of insights, restricting the data source to websites does not allow for developing an understanding of all that is happening on the ground. It is possible for the medical schools included in the current study to have, to some extent, DHT integrated in their curricula, while their official websites do not reflect so. For example, the websites may only list the course titles, and/ or not offer any information about corresponding assessments. Some medical schools may teach DHT as part of their Interprofessional Learning (as some DHT may be used by other members of the healthcare team), and hence these courses were not detected in the current study’s screening. Hence, it would be recommended for future landscape analyses to collect primary data through structured interviews with purposefully selected stakeholders. It is interesting to note that most schools which appeared to be offering DHT classes are postgraduate programs. Yet, most of the schools mentioning ‘innovation’ in the university and/ or medial program mission statements are undergraduate programs. It would be worthwhile for future studies to investigate the potential contextual enablers (e.g., existence of specific faculty members to teach DHT, national regulatory requirements, and socioeconomic status) for this observation.
Other data sources may include periodic reports and published peer-reviewed articles. In terms of future direction, as well, it would be interesting to longitudinally investigate the association between developing DHT-related competencies and the likelihood of graduates to engage with DHT in their clinical practice. It is worth encouraging medical schools to develop such curriculum-based interventions and run scientific research studies to assess their efficacy and/ or effectiveness.
