What are the main findings?
Dr. Resneck: Telemedicine, when done right, can improve access and offer convenience to patients. We have seen proven high-quality care in telemedicine services where patients are using digital platforms to communicate with their existing doctors who know them, and where doctors are getting teleconsultations from other specialists about their patients. But our study shows major quality problems with the rapidly growing corporate direct-to-consumer services where patients send consults via the web or phone apps to clinicians they don’t know.
Most of these sites aren’t giving patients a choice of the clinician who will care for them or disclosing the credentials of those clinicians – patients should know whether their rash is being cared for by a board-certified dermatologist, a pain management specialist, or a nurse practitioner who usually works in an emergency department. Some of these sites are even using doctors who aren’t licensed in the US. We also found that these sites were regularly missing important diagnoses, and prescribing medications without discussing risks and side-effects, putting patients at risk. We observed that if you upload photos of a highly contagious syphilis rash but state that you think you have psoriasis, most clinicians working for these direct-to-consumer sites will just agree with your self-diagnosis and prescribe psoriasis medications, leaving you with a contagious STD.
Perhaps the biggest problem with many of these sites is the lack of coordinating care for patients – most of them didn’t offer to send records to a patient’s existing local doctors. And when patients end up needing in-person care if their condition worsens, or they have a medication side-effect, those distant clinicians often don’t have local contacts, and are unable to facilitate needed appointments.

Response: Although many communities in the U.S. are underserved by dermatologists, access is particularly limited among Medicaid patients. Teledermatology may be one solution to improve access. Our goal with this study was to assess the effect of a novel teledermatology initiative on access to dermatologists among enrollees in a Medicaid Managed Care Plan in California’s Central Valley.
Among all patients who visited a dermatologist after the introduction of teledermatology from 2012-2014 (n=8614), 49% received care via teledermatology. Among patients newly enrolled in Medicaid following Medicaid expansion in 2014, 76% of those who visited a dermatologist received care via teledermatology. Patients of primary care practices that engaged in teledermatology had a 64% increase in the fraction of patients visiting a dermatologist (vs. 21% in other practices) (p<.01). Compared with in-person dermatology, teledermatology served more patients under age 17, male patients, nonwhite patients, and patients without comorbid conditions. Conditions managed across settings varied; teledermatology physicians were more likely to care for viral skin lesions and acne whereas in-person dermatologists were more likely to care for psoriasis and skin neoplasms.

Medical Research: What is the background for this study? What are the main findings?
Dr. Weng: Telemedicine has been around for a long time, but only recently have technological advances solidified its utility as a reliable, effective, and cost-efficient method of healthcare provision. The application of telemedicine in the field of ophthalmology has been propelled by the development of high-quality non-mydriatic cameras, HIPAA-compliant servers for the storage and transfer of patient data, and the growing demand for ophthalmological care despite the relatively stagnant supply of eye care specialists. The global epidemic of diabetes mellitus has contributed significantly to this growing demand, as the majority of patients with diabetes will develop diabetic retinopathy in their lifetime.
Today, there are over 29 million Americans with diabetes, and diabetic retinopathy is the leading cause of blindness in working age adults in the United States. The American Academy of Ophthalmology’s and American Diabetes Association’s formal screening guidelines recommend that all diabetic patients receive an annual dilated funduscopic examination. Unfortunately, the compliance rate with this recommendation is quite dismal at an estimated 50-65%. It is even lower amongst minority populations which comprise the demographic majority of those served by the Harris Health System in Harris County, Texas, the third most populous county in the United States.
In 2013, the Harris Health System initiated a teleretinal screening program housed by eight of the district’s primary care clinics. In this system, patients with diabetes are identified by their primary care provider (PCP) during their appointments, immediately directed to receive funduscopic photographs by trained on-site personnel operating non-mydriatic cameras, and provided a follow-up recommendation (e.g., referral for in-clinic examination versus repeat imaging in 1 year) depending on the interpretation of their images. The images included in our study were interpreted via two different ways—once by the IRISTM (Intelligent Retinal Imaging Systems) proprietary auto-reader and then again by a trained ophthalmic specialist from the IRISTM reading center. The primary aim of this study was to evaluate the utility of the auto-reader by comparing its results to those of the reading center.
Data for 15,015 screened diabetic patients (30,030 eyes) were included. The sensitivity of the auto-reader in detecting severe non-proliferative diabetic retinopathy or worse, deemed sight threatening diabetic eye disease (STDED), compared to the reading center interpretation of the same images was 66.4% (95% confidence interval [CI] 62.8% - 69.9%) with a false negative rate of 2%. In a population where 15.8% of diabetics have STDED, the negative predictive value of the auto-reader was 97.8% (CI 96.8% - 98.6%).

Mirna Becevic, PhD, MHA

Missouri Telehealth Network
Medical Research: What is the background for this study? What are the main findings?
Dr. Becevic: The Missouri Telehealth Network (MTN) at the University of Missouri has been providing outpatient clinical services to rural Missourians since 1995. Over 29 specialties and subspecialties have been utilized to assist patients in 69 counties. We have learned a lot along the way, what works well and what does not, in terms of telehealth protocols, trainings, best practices, etc.
The MTN holds bi-annual two day training conference for new sites to share these experiences and provide hands-on training in telemedicine. Our main goal with this study was to reach all telehealth users on the Missouri Telehealth Network (patients, providers, and telehealth coordinators-patient presenters) and learn about their perceptions of and opinions regarding this form of health care delivery. We also wanted to evaluate the overall accessibility and discernment of the MTN by telehealth coordinators, since we felt that they might need to have continuous support in order to successfully manage their telehealth programs.
Our main findings indicated that all three surveyed groups had high satisfaction with telemedicine. Patients were confident in their doctors’ medical skills, and lack of physical contact was not viewed as a barrier. Telehealth providers thought telehealth was an effective tool for providing care at a distance, but indicated that they did not prefer telehealth over in-person visits.

Medical Research: What is the background for this study? What are the main findings?
Dr. Uchino: Treatment for acute ischemic stroke is time dependent. Multiple studies have reported strategies to improve time to treatment after arrival in the hospital. Mimicking pre-hospital thrombolysis of acute myocardial infarction pioneered 30 years ago, two groups in Germany have implemented pre-hospital ischemic stroke thrombolysis using mobile stroke unit (“stroke ambulance”) that includes CT scan and laboratory capabilities. These units have been demonstrated to provide stroke treatment earlier than bringing patients to the emergency departments.
Our report extends the concept mobile stroke unit further by using telemedicine for remote physician presence. The other mobile stroke units were designed to have at least one physician on board. This allows potential multiple or geographically distant units to be supported by stroke specialists.
The study demonstrates that after patient arrival in the ambulance, the time to evaluation (CT scanning and blood testing) and to thrombolytic treatment is as quick or better as patient arrival in emergency department door. We are reporting the overall time efficiency after emergency medical service notification (911 call) in a separate paper.
