Abstract

Mobile devices have become pervasive within our society. From telecommunications to social media to professional networking platforms, mobile devices are considered a necessity by their users. With the rapid pace of technology innovation and the general evolution of medicine, it would be expected that digital learning platforms, including mobile devices, have also entered the field of medical education. The literature supports the use of mobile devices and medical mobile applications, as a supplement to traditional educational modalities, facilitating access to online medical textbooks, webcasts/podcasts, and online asynchronous classroom. These technologies have the potential of enabling learner-centered and situational learning. However, despite reported benefits there are still concerns that mobile applications focus on lower levels of learning, such as knowledge attainment, with little benefit towards higher levels of Bloom’s taxonomy, such as critical thinking. Additionally, only a small percentage of the mobile applications are regulated or accredited by governmental organizations or medical associations, which underscores the concerns regarding content quality and acceptance of its use in medical education. To address these concerns, the following paper will review and highlight the benefits and risks of mobile devices and medical applications as educational tools in medical education.

Introduction

Modern medical education has evolved to incorporate technology and the internet into their learning curriculum as electronic learning (or e-learning). The electronic learning platforms have ranged from personal computers to portable mobile devices, including tablets and smartphones. Mobile devices have revolutionized access to all types of information and data; enabling real-time and on-demand personalized communications; multimedia touchscreen displays operating at increasing speeds and with multi-functionality; delivery of data services; and providing a computing power to document and file. Purposespecific software applications, otherwise known as “apps”, have been developed to run on either computers or smartphones or both, and their use is ubiquitous. Medical and healthcare professionals have grown to depend on many applications in their daily personal lives, professional environments, and in patient-care management. Paralleling the rapid rate of health technology development, medical education has likewise evolved over the past several decades, and specific downloadable medical mobile applications can provide medical students and residents opportunities to “learn anywhere and anytime” [1]. Numerous reviews have outlined various categories of medical or healthcare smartphone applications, including applications for scheduling and communication, electronic medical textbook applications, electronic health record applications, and patient-management applications in the form of diagnostic algorithms, clinical-decision support tools, medical calculators and drug compendiums [1-9] (Table 1).

As the integration of smartphones and healthcare-related applications continues within the medical field and subsequently increases within medical education and clinical practice, a debate amongst educators and clinicians remains as to whether students and residents are benefiting from these devices and the associated applications [10-13]. Fundamentally, medical educators need to ask if there is evidence to support the assumption that smartphone usage will improve clinical competency, improve the practice of evidenced-based medicine, reduce medical errors, and in turn, improve patient outcomes. In addition to evaluating the educational advantages, it is imperative that educators, students, learners, clinicians and ultimately professional associations and regulators be aware of the disadvantages and any potential pitfalls from their adoption and usage in medical training.

Medical Mobile Applications as an Educational Supplement rather than an Educational Source

Medical education has evolved over the past decades from traditional in-person classroom lectures, textbooks and apprenticeship models, founded on behaviorist learning theories [14-17], towards a more learner-centered constructivist approach with an emphasis on competency-based learning, situational learning and critical thinking [9,13,16,17-20]. Modern medical education is now digitalized and mobile devices and applications can support both a situational-learning environment and constructivist-learning by facilitating application of the learned information to clinical practice [16,17]. Mobile devices and medical applications confer a number of benefits within the clinical sphere and medical education. However, it needs to be addressed that mobile applications should be a used as an educational supplement rather than an educational source. One of the major motivating factors for using mobile medical applications is the easy accessibility to large amounts of information. Medical professionals in training, including medical students and residents, use these software applications to enhance their learning, skill development and medical competence. Students are able to carry clinical resources on their person in a convenient, compact and searchable package, which functions as a portable electronic library [8]. Using these resources, medical applications provide an opportunity for learners to participate in their learning process by accessing explicit information and applying it to clinical situations, thereby enabling more effective learning and retention of knowledge experiences, ultimately resulting in improved patient care [4,10,21].

Additionally, trainees report their preference to this learning platform over computers and textbooks, as they provided faster access to information, resulting in less delays during clinical ward rounds and more confidence in collaborating with staff and patients [1,6,11,22-24]. Students and resident trainees report using their mobile applications 39% of the time in the clinical environment and 51% of the time for educational purposes [3]. Studies have consistently demonstrated that mobile applications can improve learning outcomes. Systematic reviews, which have included health science students and medical residents, have demonstrated superior test scores in the range of 8-15%, amongst learners who supplemented their learning with mobile applications compared to those who only used traditional learning methods [9,13,21,25]. A concern voiced by educators includes the potential that when learners access information rapidly it may inhibit a deeper internalization of knowledge, a key component of the knowledge acquisition [6,12,26]. However, the studies reporting improved test scores did not consider mobile applications as a sole educational resource, but rather as a supplemental one [6,9,21,25,27]. In fact, it could be argued that mobile and electronic learning provides additional opportunities to learn while practicing evidence-based medicine, thereby integrating the knowledge and skills attained and transposing them into clinical practice, a crucial component of both physician competency and patient care [23,28].

In a review of seven randomized trials of healthcare professionals using mobile devices, those clinicians who used their mobile devices in accessing medical information reported better decision-making and better retention of information, when compared to peers who used the equivalent paper resources [17,29]. By providing opportunities to practice evidence-based medicine at the patient’s bedside, trainees can develop their higher levels of learning including, critical thinking and problemsolving abilities. In order to practice evidence-based medicine and incorporate medical applications in its fold, it is imperative that there is app-literacy amongst learners and clinicians. Reports include a range of 85- 91% of medical students and residents using their mobile devices and medical apps on a daily basis, compared to 10% of learners using hardcopy textbooks and 20% using electronic textbooks via a desktop computer [10,30]. Yet, an average of 47% of surveyed participants, students and residents alike, report difficulty in finding reliable and accurate learning resources, a finding echoed in other studies [3,6,26]. As mobile medical applications are increasingly being used in clinical practice, medical students and residents, in addition to other healthcare practitioners, will need to critically appraise the content presented in the medical applications as ‘evidence-based’, and thus possibly, useful in clinical practice.

This skill of critically appraising medical applications as they are being used concurrently in clinical training may result in the issue of a hidden curriculum within an EBM focused medical training program and will require the support of academic and medical institutions [31-34]. Recognizing that the present and the future of medical education will involve the integration of mobile devices and medical applications into their undergraduate curriculums and their postgraduate training programs, numerous medical schools have been increasingly supportive of their use by their learners [21,22]. As greater involvement from universities, postgraduate education programs, medical associations and professional bodies continue, more advanced applications can be developed, which may further support educational needs, while providing guidelines on their clinical usage.

Cost versus Content Quality of Medical Mobile Applications

While many medical applications are freely downloadable, others may be associated with an initial subscription fee and further maintenance fees. Considering that the commonly used reference app, Uptodate, has an annual fee of approximately $520 US Dollars for an annual subscription [35], this cost may result in inequitable access amongst learners of different socio-economic backgrounds (and countries). In a Canadian study, approximately 38% of students and residents reported paying for 1-4 medical applications [36] yet another study reported that approximately 43% of these learners cited cost as a significant limiting factor in acquisition [6]. Medical applications may also be supported through “pushed” advertising, however, there are concerns that applications sponsored by industry may present biased information or have poorer content quality [21,36,37]. This is a significant concern as medical and cyber experts estimate that approximately one-third of available medical software applications are developed without the input of appropriate medical professionals [2]. Furthermore, government regulation is still limited as the American Federal Drug Administration (FDA) and Health Canada have only partial and limited oversight of mobile medical applications with particular focus on applications that may be used as medical devices [2,19,38,39]. Issues regarding the reliability and accuracy of medical applications are serious concerns and have significant implications for medical error. Mobile applications, if misused, misinterpreted or if the content that is inaccurate or unreliable, can result in erroneous diagnosis and therapeutic management of patients, thereby posing a potential risk to the general public [39,40,41].

As trainees and clinicians increasingly refer and rely on information provided by medical applications it is therefore crucial that the content be accurate, reliable and of the highest quality [39,40,41]. Examples regarding poor reliability and inaccurate content have been demonstrated in numerous studies; in a study comparing 23 different opioid conversion apps, inconsistencies and inaccuracies with little concordance between the different opioid conversion calculators were reported [42]; another study comparing 55 marketed pregnancy applications aimed at estimating due dates, reported inaccuracies or no medical references in 71% [43]; additionally, the well-known example of the dermatology application SkinScan reported a concordance rate of 10.8% in melanoma diagnosis (a highly malignant skin cancer), when 93 clinical images were compared between the application and references from the National Cancer Institute and Fitzpatrick Dermatology in General Medicine [44]. Ideally, medical applications need to provide reliable, relevant, accurate and up-todate information, while being fiscally accessible for all users, thus avoiding the debate on cost versus content quality. Evaluationtools, including the Health on the Net Foundation (HON), and the Agency for Healthcare Research and Quality (AHRQ) [34], offer a “how to critically appraise” mobile medical applications guide, which consider the content quality, authorship credibility, financial transparency, cost and utility within a clinical context (Table 2). Additionally, online sites, endorsed by professional associations can also recommend unbiased, reliable medical and peer-reviewed applications, including the Medical App Journal and the Journal of Medical Internet Research [2].Recognizing the issue of cost and affordability, medical Institutions, universities and professional associations have also begun to offer endorsed medical applications through their internal information technology programs [2,21,36]. By financially supporting and absorbing the cost of these applications, learners will be able to freely access these reliable and endorsed educational supplements to further support their learning process, without the additional concern of jeopardizing content quality for cost [21,22].

Acceptance of the use of Medical Mobile Application’s by Faculty and Patients

Despite the widespread use of smartphones in our daily lives and their incorporation in healthcare and medical education, the acceptability of their use in the classroom and in the clinical setting still remains a hurdle which can negatively impact the learner-teacher and clinician-patient relationship. On one side of the looking glass, patients and teachers may view mobile devices as distractions, potentially resulting in patient resentment and frustration by teachers. Studies have reported that while 75% of faculty felt that mobile devices are useful educational tools, they were nevertheless a distraction in the classroom, and amongst the faculty surveyed, 46% felt that mobile devices were also a distraction in the clinical environment [26]. Further to this, a number of surveys have reported patients’ and faculty’s perceptions of rudeness, laziness and disinterest when smartphones were used in the clinical setting [1,3,10,22]. These perceptions often leave students and residents in an unfortunate position; either they do not use these educational supplements or if they do then they feel the need to justify their use [10,12,22]. It is important to recognize the negative consequences of these perceptions and how they may negatively impact learning and patient care. Educators and faculty need to become knowledgeable of how medical applications, as with any other technology, are an integral part of medical education. Mobile devices are commonplace and are used at an average rate of 85-87%, amongst medical professionals [24]. It has been established that mobile devices and medical applications provide portability, flexibility and rapid accessibility to large amounts of information enabling healthcare professionals to refer to evidencebased medicine immediately and answer clinical questions during a patient encounter [11,24].

Furthermore, as a learner’s medical career matures, there will be differences on how these devices are used, to what frequency and which software applications are being referred to [6,36,45]. In general, students will use their devices for note-taking and reviewing online textbooks and lectures, while residents will use their devices for drug-references, clinical calculators and journal articles, and clinicians will refer to subspecialty clinical decision support applications, prognostication clinical calculators and drug references [1,2,6,24,30,36,45]. Improved patient-care via the use of mobile applications in the clinical environment can further be evidenced during the transition period as medical student’s transition to resident doctors, and as these residents transition to staff physicians [11].As patient care is becoming increasingly complex and providing medical care is still expected to be efficient, safe and of the highest quality, the stakes are high and these new physician residents often feel unprepared when it comes to decision making, and prescribing therapy [30,37,45]. In order to provide optimal patient care, physicians will rely on clinical decision support systems and drug reference applications [11,24,46].

Studies have reported that whereas non-smartphone physician users would only search for answers to clinical questions in 6% of their cases, smartphone owners were successful 95% of the time when they referred to medical information on their phones [19,46]. When these decision support applications are used, inappropriate investigations are avoided, while appropriate tests and therapies are ordered in a timely manner with an increase in the average rate of appropriate electronic ordering and patient management from 52% to 64%, and a decrease in medical order error rates from 22% to 8% [3,7,11,19,29]. As mobile applications, these decision support tools can be readily accessed by residents and clinicians in order to make immediate evidence-based decisions while avoiding harm in potentially stressful situations where critical information retrieval is time-sensitive and crucial [8,11,47]. Finally, it is without a doubt that effective and reliable communication amongst healthcare professionals and their patients is crucial component of patient management. In this regard, mobile devices have significantly improved communication beyond simple phone calls and text messaging with applications designed for Multimedia Messaging Services (MMS), emails, video-conferencing, and instant peer-to-peer or clinician-patient communication capabilities, thereby improving patient care and outcomes [26]. Communication within medical education has improved as learners and their educators are able to communicate and collaborate through messaging groups, video-conferencing and social media, without the added stress of coordinating different schedules (and locations) for in-person meetings [26,48]. Further to this, mobile devices can facilitate communication with remote areas (countries or continents) with limited (or no) access to local specialists, providing equitable medical care on a local and global basis [8,48]. Likewise, patient-care has evolved with Electronic Health Records (EHR) being available as mobile secured applications, which has further enabled clinicians to conveniently review and respond to patient-related issues rapidly and remotely. These electronic health records, along with the various communication platforms, enable healthcare providers to communicate rapidly amongst themselves and provide bi-directional physician-patient communication, particularly in the cases of chronic diseases [8,11,19,28,49,50]. Mobile devices and medical applications are able to provide learners and clinicians, rapid and reliable educational tools which can be used in a situational context for immediate and improved patient care, as well as provide communication versatility amongst healthcare professionals and with patients. Understanding these roles that medical applications have in medical education and clinical care, how their use are beneficial towards patient-care, will lead to a wider acceptance of mobile devices and medical application use in the clinical environment by educators, faculty and ultimately, patients.

Conclusion

Over the last 50 years technology has changed our personal and professional lives. The practice of medicine has also rapidly evolved over this period thanks in part to the advancement of science and medicine but also the improvement in communication and the speed of knowledge dissemination. As medicine and technology intertwine and advance together, there is an increasing demand and expectation for accurate, reliable and efficient medical care. To answer these expectations, modern medical education has evolved from traditional behaviorist learning models which included in-person classroom teaching and apprenticeships, towards situational and constructivist learning models, with the incorporation of online classes, web-conferences, simulation learning, virtual-reality learning, podcasts, chat groups and social media, to name just a few. Amongst the e-learning tools, mobile devices and mobile medical software applications are being used by medical students, residents and faculty at an exponential rate. Clinician-educators have expressed concerns that smartphones and mobile applications may serve as ‘shortcuts’ to effective learning, potentially causing some learner-educator discordance, foster superficial learning, detract from acquiring deeper learning, and undermine a learner’s potential for critical thinking and problemsolving skills [6,13].

Upon review of the published literature, these concerns appear to be unfounded and not evidence-based. Medical students and residents are using these technologies as an educational supplement, referring to evidence-based medical information in real-time and within clinical context, thus enhancing their learning activities, while providing efficient, safe and optimal standard of care for their patients. If we consider a situational and constructivist approach to learning, these mobile ‘shortcuts’ to information can be accessed, while at the patient’s bedside and applied in the clinical context immediately, thereby enabling learners to easily integrate the new information into their foundational knowledge immediately, resulting in better retention and new knowledge constructs being formed. Thus, it could be argued that rather than undermine learning, mobile devices and their applications enable residents to ‘read around’ clinical cases in real time, when retention is the most optimal [23,24,28,30]. Furthermore, studies that reported the improved learning outcomes of those students and residents using mobile devices, considered their use as an educational supplementary tools, rather than as educational sources [1,21,24,25,27,45,47]. Furthermore, how these medical applications will be used by students, residents and clinicians will differ at the various stages of their career; students will refer to online textbooks and lectures for information gathering, while residents will more often refer to clinical decision support applications, drug references and prognostication clinical calculators [1,6,24,45]. Thus far the literature has demonstrated that the benefits of mobile devices and medical applications in knowledge and evidence-based clinical training outweigh the educational concerns, it is therefore important that educators not only accept smartphone and medical application use but support their learners using these educational supplements.

The cost and the accessibility of medical applications, the quality and reliability of the medical information provided by the applications will require scrutiny and input from medical professionals. Recognizing that there are some applications of questionable quality, users will need to be aware of which applications were developed with contributions from medical professionals, government-regulated, peer-reviewed and endorsed by institutions and professional bodies [2,42]. As educators and clinicians become skilled at appraising medical applications, it will become crucial to transfer that knowledge to learners, while universities and institutions will need support and provide learners with endorsed, peer-reviewed applications without cost concerns [2,3,21]. The future of mobile devices and the widespread acceptance of reliable and accurate medical applications in medical education and patient care is tangible. The literature has consistently demonstrated improved educational outcomes, improvements in patient care outcomes and decreases in medical errors. The versatility, accessibility and reliability of mobile devices and the numerous mobile applications will enable equitable and improved patient care. Thus, the beneficial use mobile devices and associated medical software applications can be extended beyond medical education and be applied to patient care, as a whole. It can, therefore, be concluded that the benefits of smartphones and medical applications outweighs their potential pitfalls.
