Home telecare technologies for the elderly.

There are many home telecare technologies which have been developed specifically for chronic diseases and there are some more generic technologies that could be used as well. For home telecare, the equipment must be certified, the operational routines must be reformed, the infrastructure must be in place, the market must be prepared, the health authorities must be convinced that the system will work and the cost-effectiveness must be evaluated. Organizational and societal changes, such as cost reduction policies and an aging population, are the main driving forces for the development of home telecare, especially for elderly patients. At the moment there is no holistic model for scientific evaluation from different perspectives (e.g. clinical, legal, technical). We suggest that more research on home telecare and its effects needs to be conducted, in order to provide evidence for optimizing the use of this promising technique.

The potential of digital monochrome images versus colour slides in telescreening for diabetic retinopathy.

We explored the potential of digital monochrome images as an alternative to colour slides in screening for diabetic retinopathy. Twenty-eight patients with diabetes were recruited for the study and 20 actually participated. Using a fundus camera (Nikon 505AF) one set of three digital images and one set of three colour slides were taken per eye. Two independent ophthalmologists graded the colour slides and the digital images for diabetic retinopathy. The ophthalmologists spent about two minutes grading each set of images, suggesting that specialists could potentially screen a large number of patients. The agreement between the two screening methods was 0.95 and 0.89, with respect to disease or no disease. The agreement (kappa) between the two ophthalmologists for grade of retinopathy was 0.47 when colour slides were employed and 0.61 when digital monochrome images were employed. The results indicate that digital red-free monochrome images represent a superior screening tool for diabetic retinopathy. Tele-screening may be beneficial when patients have to travel substantial distances to visit an ophthalmologist.

Challenges in telemedicine and eHealth: lessons learned from 20 years with telemedicine in Tromsø.

The Norwegian Centre for Telemedicine (NST) has, over the past two decades, contributed to the development and implementation of telemedicine and ehealth services in Norway. From 2002, NST has been a WHO Collaboration Center for telemedicine. In August 1996, Norway became the first country to implement an official telemedicine fee schedule making telemedicine services reimbursable by the national health insurer. Telemedicine is widely used in Northern Norway. Since the late 1980's, the University Hospital of North-Norway has experience in the following areas: teleradiology, telepathology, teledermatology, teleotorhinolaryngology (remote endoscopy), remote gastroscopy, tele-echocardiography, remote transmission of ECGs, telepsychiatry, teleophthalmology, teledialysis, teleemergency medicine, teleoncology, telecare, telegeriatric, teledentistry, maritime telemedicine, referrals and discharge letters, electronic delivery of laboratory results and distant teaching for healthcare personnel and patients. Based on the result achieved, the health authority in North-Norway plans to implement several large-scale telemedicine services: Teleradiology (incl. solutions for neurosurgery, orthopedic, different kinds of surgery, nuclear medicine, acute traumatic and oncology), digital communication and integration of patient data, and distant education. In addition, the following services will also be considered for large-scale implementation: teledialysis, prehospital thrombolysis, telepsychiatry, teledermatology. Last in line for implementation are: pediatric, district medical center (DMS), teleophthalmology and ear-nose-throat (ENT).

Prioritisation of telemedicine services for large scale implementation in Norway.

In late 2005, the Northern Norway Regional Health Authority requested an evaluation of all tested telemedicine services in northern Norway to clarify which were suitable for large scale implementation. A total of 282 reports from the Norwegian Centre for Telemedicine, the University Hospital of North Norway and the University of Tromsø were included in the study. Projects not focusing on secondary health care were excluded and 46 studies representing 21 topics entered the final analysis. They were analysed with a self-developed scoring tool focusing on five items. Eleven topics were concluded as being candidates for large scale implementation and grouped according to priority. The first priority topics were teleradiology, digital communication/integration of patient records and education. The second priority topics were teledialysis, pre-hospital thrombolysis, telepsychiatry and teledermatology. The third priority topics were paediatrics, district medical centres, tele-ophthalmology and tele-otorhinolaryngology. No priority was suggested for the projects in cardiology, endocrinology, geriatrics, gynaecology/obstetrics, pathology and nursing/care. User support, training, research ability, financial incentives and interaction between clinicians and ICT-personnel were considered as important factors in motivating health-care personnel to use telemedicine.
