The current model of ophthalmic care requires the ophthalmologist’s involvement in data collection, diagnosis, treatment planning, and treatment execution. We hypothesize that ophthalmic data collection and diagnosis will be automated through mobile devices while the education, treatment planning, and fine dexterity tasks will continue to be performed at clinic visits and in the operating room by humans. Comprehensive automated mobile eye diagnosis includes the following steps: mobile diagnostic tests, image collection, image recognition and interpretation, integrative diagnostics, and user-friendly, mobile platforms. Completely automated mobile eye diagnosis will require improvements in each of these components, particularly image recognition and interpretation and integrative diagnostics. Once polished and integrated into greater medical practice, automated mobile eye diagnosis has the potential to increase access to ophthalmic care with reduced costs, increased efficiency, and increased accuracy of diagnosis.

Although mobile technologies, devices and software have enriched our lives in many ways, including medical applications, the potential negative effects are often overlooked. A growing amount of evidence suggests that there are potential negative impacts of smartphones on biophysiological processes, especially on sleep.16 Studies have shown that blue lights, especially the short-wavelength light (380 ~ 495 nm) emitted from smartphone monitors, disrupts circadian rhythm by retarding nocturnal melatonin production.7

Dear Readers,

7th July, 2016

It is with great pleasure that we present the second issue of the Journal of Mobile Technology in Medicine for 2016 with excellent examples of translational mHealth research. One of the great challenges confronting global health care is accessibility and affordability to diagnostic technologies and timely referral to specialist services.

In this issue, Ludwig et al provide a brief overview of the existing technologies available to aid automated diagnostic and referral in the field of the ophthalmology. The authors provide a summary of a potential pathway for automated ophthalmic care through the use of mobile diagnostic devices that can facilitate image collection. The first step in the clinical algorithm is safe and accurate image capturing technologies. The authors highlight examples of mobile diagnostic adapters developed by the Peek Vision group (UK), D-eye system (Italy), and iExaminer (Welch Allyn) which convert the modern smartphone into an anterior and posterior segment image capturing device. These images can then be collated, filtered for quality, and interpreted by automated software and results can, in theory, be graded in real-time to provide risk stratification and triaging of patients.

Whilst the concept of automated diagnostics in ophthalmic care is not new, the challenge over the last 20 years has been to develop algorithms that meet sensitivity and specificity criteria to be safe for day to day real world clinical practice.1 Ludwig et al succinctly illustrate examples whereby the two common modes of automated image analysis, neural networks and deep learning are now meeting the level of reliability and reproducibility for safe clinical practice. Importantly, Ludwig et al highlight examples of the utility of automated grading technologies developed for two of the most common, yet insidious causes of global vision loss, glaucoma and diabetic retinopathy.

The evolution of automated diagnostic technologies now truly positions health care in the 21st century to reach and provide care to a greater population breadth than ever before. The benefits of such technologies will always be balanced by the caveats of the necessity for clinical correlation by a specialist or appropriately trained medical professional, the costs of equipment, and the need for further evidence in larger population based studies. This is particularly poignant for automated software based learning. Nevertheless, there is a clear value in ability of these technologies to facilitate early diagnosis, triaging and timely referral of patients in rural and remote and low-resourced settings, where the greatest burden of global morbidity exists.

Background: For health campaigns, pretesting the channel of message delivery and process evaluation is important to eventual campaign effectiveness. We conducted a pilot study to pretest text messaging as a mHealth channel for traditionally underserved patients.

Aims: The primary objectives of the research were to assess 1) successful recruitment of these patients for a text message study and 2) whether recruited patients would engage in a process evaluation after receiving the text message.

Methods: Recruited patients were sent a text message and then called a few hours later to assess whether they had received, read, and remembered the sent text message.

Results: We approached twenty patients, of whom fifteen consented to participate. Of these consented participants, ten (67%) engaged in the process evaluation and eight (53%) were confirmed as receiving, reading, and remembering the text message.

Conclusion: We found that traditionally underserved and under-researched patients can be recruited to participate in a text message study, and that recruited patients would engage in a process evaluation after receiving the text message.


App Competition Open: Reimagining Diabetes Management via IBM Watson Health and the American Diabetes Association

Posted on Jul 13, 2016 in News | 0 comments

The American Diabetes Association has announced a new competition for app developers proposing cognitive computing solutions for diabetes. Clinical and research data from the ADA’s vast repository will be made available via IBM Watson Health.

Announced at the ADA’s 76th Scientific Sessions in June, app developers will have the chance to reimagine how diabetes is managed through Watson’s data analysis. Watson will enable healthcare providers, researchers, institutions and patients to all benefit from more streamlined and efficient data analysis. Data is deidentified and shared via Watson’s cloud system, enabling secure and timely access for app developers across all facets of healthcare to explore app-based solutions for diabetes prevention, treatment and management.

“Patients, caregivers and healthcare providers need access to cognitive tools that can help them translate that big data into action, and Watson can offer access to timely, personalized insights,” said Kyu Rhee, MD, MPP, and IBM Watson Health’s chief health officer. As 29 million Americans have diabetes according to the Centers for Disease Control and Prevention, with 415 million adults worldwide, the opportunities from this partnership will help accelerate the fight against this chronic disease.

Australian Cancer patient app CancerAid set to launch in Asia

Posted on Jun 19, 2016 in News | 0 comments

Australian startup CancerAid will launch in Asia with the Hong Kong Integrated Oncology Centre.

The biggest problem cancer patients and their families face is digesting the bewildering amount of information they are given throughout their journey.

CancerAid aims to solve this problem by providing a secure communication and information portal for the millions of people affected by cancer worldwide.

CancerAid was founded in Sydney in 2014 by radiation oncology doctor, Nikhil Pooviah. Its mobile app features, such as the Journey Organiser and Treatment Plan, will help patients keep track of appointments and record information they can then share with their loved ones and treating team. The app can be personalised to each patient’s individual cancer subtype and treatment program. Patients will also be able to access help from Allied Health members, and be able to communicate with cancer specialists who are registered with the program.

CancerAid will launch in Australia later in 2016.
