TED talk: Dr Daniel Kraft discusses the scope of mobile technology in medicine

This is an entertaining talk presented by Dr Daniel Kraft (MD, track chair of Singularity University and chief medical officer for RegenMed Systems) on the potential of mobile technology to revolutionise medical practice. It eloquently summarises the contemporary technology available and provides a glimpse of how mobile technology can be integrated for personalised management of the individual patient in the not too distant future. A highly recommended talk.

The need for evidence-base practice for using mobile technology in medicine

Modern medical practice is undergoing a transformation in the way it communicates and provides healthcare. The evolution in medicine has been promulgated fundamentally by the human desire to provide and receive a high standard of affordable medical care within an appropriate time. This has been facilitated by advances in modern technology. But whilst a tsunami of easily accessible technology has engaged the attention of the medical community and improved access to medical care, particularly in remote areas, there is always an element of concern into safety, reliability, reproducibility and accuracy of mobile technology systems.

The strength of western medical practice is the establishment of evidence-based principles and guidelines.  The concept of evidence-based medicine (EBM) is to merge clinical experience and patient values with the best available research.1  The purpose of this is not to create a rigid, automated framework that eliminates the clinician’s judgement, but rather a logical framework that facilitates decision making and can be applied to the care of the individual patient.  This concept of EBM is now entrenched in medical school curricula, such that junior doctors are taught to think in a scientific rather than an arbitrary manner. Therefore, whilst the advent of telemedicine and other mobile technologies have the potential to improve access to patient assessment, treatment and monitoring, until such methods are appropriately scientifically validated there will always be a hesitance from the medical fraternity to adopt these technologies into routine practice. In 2009, Thomas et al published a study of the use of off-site display of patient parameters in several intensive care units (ICU), whereby clinicians located away from ICU were able to view patient parameters and make treatment decisions.2  At the conclusion of the study there was no significant difference in mortality and length of stay trends between the conventional and “trial” off-site telemedicine practice. Chen’s article in the New York Times portrayed the polarized sentiment of doctors on this issue.3  Clearly some may feel the emergence of telemedicine alters the clinician-patient relationship and raises concerns over patient safety. Conversely, another school of thought relates to practical considerations whereby remote access technology may facilitate timely care or referral for patients. In a vast continent such as Australia, the advent of radio communication was a critical milestone for the success of the Royal Flying Doctor Service (RFDS) in providing medical care to remote communities. At present, telehealth accounts for one third of the 277,000 RDFS patient contacts per annum.4 These figures vindicate that modern medicine must adopt the principles of evidence based medicine in keeping up with the rising demand in order to assess what modalities of telemedicine are best suited to different environments.

The advances in technology and affordability of hand-held devices have ensured that telemedicine will be an integral part of medical practice in the near future. It is clear that this is more than a phase of curiosity. In May 2011, the Manhattan Research Group survey of medical practitioners in the United States demonstrated that 75 per cent of physicians have purchased an Apple Inc. mobile device such as iPad, iPhone, iPod.5 Prior research by the same group earlier concluded that up to 30 per cent of doctors are using iPads to access patient records, radiology investigations and communicate with their patients. These trends reflect the rapidly growing demand for fast, readily available information access to facilitate clinical decisions in a more efficient manner. A search of the Apple “Appstore” reveals over 5300 medical, health and fitness applications. These range from medical reference resources for patients and clinicians, to medical calculators, examination instruments, and information storage programs across a spectrum of medical disciplines. Yet as the market for such “apps” increases exponentially, one must be cautious with their validity as quality does vary. This is particularly relevant to programs that can be readily installed onto a mobile phone with the promise of converting it into an examination instrument, for example a chart to test colour vision.  Whilst it can be argued that a natural process of censorship of may occur as these applications can be rated by consumers, this merely equates to level five evidence. Thus, before such applications are adopted into routine practice clearly there needs to be a scientific review of their validity.

The integration of accessible and affordable health technology is one of the six pillars of an effective health system as defined by the World Health Organisation.6  Mobile technology and telemedicine are arguably one of the most dynamic fields of medicine with the greatest potential to change clinical practice for the better. In order for it to be successfully integrated into practice, healthcare workers and patients need to be assured of its scientific validity. It is therefore imperative for patient care that we do not compromise on the principles of evidence-based medicine in making the transition.
