MedicalResearch.com Interview with: Shi Lili Department of Medical informatics and Nantong University Library Nantong University, Nantong, China Medical Research: What is the background for this study? What are the main findings? Response: Diabetic retinopathy (DR) is the most frequently occurring complication of diabetes and one of the major causes of acquired blindness in the working-age population around the world. DR can be detected using various methods. Telemedicine based on digital photographs of the fundus is being used with increasing frequency to detect DR, and especially for Diabetic retinopathy screening. The purpose of our study was to assess the diagnostic accuracy of telemedicine in the full range of DR and DME severity compared with the current gold standard. We found that the diagnostic accuracy of telemedicine using digital imaging in DR was overall high. It can be used widely for Diabetic retinopathy screening.

Rashid Bashshur, PhD Senior Advisor for eHealth Professor Emeritus, Department of Health Management and Policy Executive Director, UMHS eHealth Center University of Michigan Health SystemMedicalResearch.com Interview with:  Rashid Bashshur, PhD Senior Advisor for eHealth Professor Emeritus, Department of Health Management and Policy Executive Director, UMHS eHealth Center University of Michigan Health System Medical Research: What are the Main findings of the study? Dr. Bashshur: The main findings can be summarized as follows:
  •  The prevalence of chronic disease is increasing due to the changing demographic composition of the population and unhealthy life styles. Chronic diseases are expensive, accounting for about 70% of health care expenditures;  but  they are amenable to telemedicine interventions.  These interventions consist of ongoing monitoring of patients living in their own home environments, engaging them in managing their health,  providing them with educational materials and the necessary tools to manage their life style mostly by avoiding risky behaviors and adopting healthy ones.
  • Telemedicine interventions consist of various configurations of technology (telephone, video, wired or wireless, automated or manual) , human resources (physicians, nurses, combinations, and patient populations at various levels risk levels or severity of illness, The interventions investigated to date also vary in terms of study design, duration of application (during the study period), and frequency of administration of the intervention.  Hence, the findings must be viewed from the perspective of the specific methodological attributes  of the studies that were performed.
  • Using only robust studies from 2000 to the near present, and limited to congestive heart failure, stroke and COPD.  With notable exceptions,  overall there is substantial and fairly consistent evidence of:
  • A decrease in use of service, including hospitalization, rehospitalization, and emergency depart visits as a result of the telemedicine intervention.
  • Improved health outcomes.
  • Improved event timing for stroke patients.
  • Reduced exacerbations of symptoms for COPD patients
  • Some interesting  trends  to be considered:
  • Frail and elderly patients, those with co-morbid conditions, and those in advanced stages of illness are not likely to benefit from telemedicine interventions, as compared to their counterparts.
  • Visual information as in videoconferencing proved superior to telephone only connection for the diagnosis and treatment of stroke patients.
  • There could be a tradeoff between extra nursing time versus reduced physician time in some settings, but the net effect is cost savings.
  • There seems to be a paradoxical telemedicine effect in terms of increasing longevity but no reduction in hospitalization, reported in few studies.

Mary G. Lynch, MD Professor of Ophthalmology Atlanta Veterans Affairs Medical Center Decatur, Georgia. Department of Ophthalmology, Emory University School of Medicine, Atlanta, GeorgiaMedicalResearch.com Interview with: Mary G. Lynch, MD Professor of Ophthalmology Atlanta Veterans Affairs Medical Center Decatur, Georgia. Department of Ophthalmology, Emory University School of Medicine,  Atlanta, Georgia Medical Research: What are the main findings of the study? Dr. Lynch:
  • Since 2006, the VA has been systematically using teleretinal screening of patients with diabetes to screen for retinopathy in the Primary Care Clinics. Under this program, 90% of veterans with diabetes are evaluated on a regular basis. A number of patients who are screened have findings that warrant a face-to-face ophthalmic exam. No information exists on the effect of such a program on medical center resources.
  • 1,935 patients  underwent teleretinal screening through the Atlanta VA over a 6 month period.  We reviewed the charts of the 465 (24%) of the patients who were referred for a face to face exam in the Eye Clinic.
  • Data was collected for these patients to determine the reasons for referral, the accuracy of the teleretinal interpretation, the resources needed in the Eye Clinic of the Medical Center to evaluate and care for the referred patients over a two year period and possible barriers to patient care.
  • Of the 465 patients referred for an exam, 260 (55.9%) actually came in for an exam. Community notes were available for an additional 66 patients. Information was available for 326 (70.1%) of the referred patients.
  • The most common referring diagnoses were nonmacular diabetic retinopathy (43.2% of referrals), nerve related issues (30.8%), lens or media opacity (19.1%), age-related macular degeneration (12.9%) and diabetic macular edema (5.6%).
  • 16.9% of the referred patients had 2 or more concurrent problems that put them at high risk for visual loss.
  • The percentage agreement between teleretinal screening and the ophthalmic exam was high: 90.4%. Overall sensitivity was 73.6%. The detection of diabetic macular edema had the lowest sensitivity.
  • A visually significant condition was detected for the first time through teleretinal screening for 142 of the patients examined (43.6%).
  • The resource burden to care for referred patients was substantial.
  • 36% of patients required 3 or more visits over the ensuing 2 year period.
  • The treatment of diabetic macular edema had the highest resource use involving on average 5 clinic visits, 6 diagnostic procedures and 2 surgical procedures
  • The most common non-refractive diagnostic procedures were visual fields and optical coherence tomography.
  • The average cost to care for the referred patients (in Medicare dollars) in work RVUs alone was approximately $1,000 per patient. The cost to care for a patient with diabetic macular edema was $2673.36.

Medical Research: What are the main findings of the study? Dr. Kroenke: The telecare intervention including monitoring of pain using automated phone calls or the Internet with contacts by a nurse care manager who met weekly with a physician pain specialist to discuss treatment of new patients or patients already being followed who were not improving.
  • Almost twice as many patients in the telecare group had improvement in their pain compared to the usual care control group (52% vs. 27%).
  • Moreover, nearly twice as many patients in the usual care group got worse over 12 months (36% vs. 19%).  Thus, patients with chronic pain may not only fail to improve with current treatment, they in fact can get worse over time.
  • Although one-third of these chronic pain patients were on opioids at start of study, there were very few patients in which opioids needed to be started or dose increased.
  • The intervention group was about equally divided between those who chose to do automated symptom monitoring (ASM) by IVR (51%) or internet (49%).  The majority of patients rated the monitoring as easy to do, and the telecare intervention helpful.

Dr. Misha A. Rosenbach Assistant Professor of Dermatology Hospital of the University of Pennsylvania Section Editor, JAMA Dermatology Patient PageMedicalResearch.com Interview with: Dr. Misha A. Rosenbach Assistant Professor of Dermatology Hospital of the University of Pennsylvania Section Editor, JAMA Dermatology Patient Page MedicalResearch.com: What are the main findings of the study? Dr. Rosenbach: There is strong agreement between teledermatologists and in-person dermatologists when evaluating inpatients at a tertiary care academic hospital.  The primary aim of this study was to assess telederm as a triage tool.  Many dermatologists are not full-time hospitalists, but work in private practice or clinics which may be remote from affiliated hospitals.  The goal was to evaluate whether teledermatology could help those providers assess the acuity of inpatient consults.  There was strong concordance.
