“…The barriers to the implementation of telehealth were: 19,33,44,45,48,53,54,57,67 Software incompatibility between two or more countries or institutions; Internet congestion causing delays or a low frame-rate of the video pictures and interruptions and delays in voice transmission; High communication charges and equipment costs; Other communication problems like a change of IP address and configuration of the receiving network, a broken cable at the host network and alteration of the cabling at the host site without authorization; Untrained service providers including physicians and staff; Small sample size and lack of follow up; Poor infrastructure and other logistical challenges. …”

We conducted a systematic review of the literature on telehealth in Asia. The Medline database was searched, together with three specialist journals, for peer-reviewed articles published in the ten years to June 2007 which were related to any telehealth application involving one or more Asian country. Out of the 1504 abstracts retrieved, 109 articles were selected by two independent reviewers for the final review. The number of published articles on telehealth in Asia increased during the review period. The largest number of studies were conducted in Japan (37%). Most telehealth applications were based on the store-and-forward modality (43%), with 35% using videoconferencing and 15% using a hybrid approach. Most of the studies were descriptive (75%) and only eight included a control group against which telehealth was compared. The most common means of telecommunication was ISDN lines, which were employed in 32% of the studies. Some 40% of the studies mentioned improved quality of health care; about 20% mentioned improved access to health care. Although most studies mentioned cost, only 13 of them assessed resource utilization and cost. The overall findings gave a generally optimistic picture of telehealth in Asia. However, there is a lack of good quality studies.

“…Teleradiology within Singapore was first explored in the public sector in the 1990s when efforts were made to establish teleradiology consultation between Stanford University and Singapore General Hospital for magnetic resonance imaging (MRI) and computed tomography (CT) studies. 7 Similar services in the private sector commenced in 1992 (personal communication -Kwok R, Hoe J, Lim PS) for teleradiology of plain radiographs and ultrasound. These attempts remained isolated initiatives, mainly due to the prohibitive cost of the infrastructure and the technological limitations in the past.…”

Teleradiology will have a significant impact on the delivery of healthcare and the practice of medicine. In order to ensure a positive outcome, the expected benefits, limitations and potential pitfalls of teleradiology must be carefully considered. For Singapore, teleradiology can be used to facilitate a quantum leap in the standards of radiological services. This can be achieved through the development of an integrated, nationwide, high-speed radiology network which will allow patients to have access to high-quality and responsive subspecialty radiology expertise located throughout the country. If judiciously implemented, teleradiology has the potential to propel Singapore radiology to an unprecedented level of professional quality and service delivery, and will provide the framework for sustainable radiological insourcing from other countries.

“…One application of teleradiology is to enable radiologists to provide after-hours support to hospital emergency departments and intensive-care units. While many earlier studies have looked at the appropriateness of using teleradiology for the interpretation of plain radiographic images 2,3 , recent studies have examined its use for multi-image modalities, such as computerized tomography (CT) scans 4,5 . Png et al described an international teleradiology project in which interesting CT and magnetic resonance images were transmitted for the purpose of obtaining a second opinion 4 .…”

Although most teleradiology work has used relatively expensive equipment, a flatbed scanner has been described as a low-cost alternative in a prospective study involving the transmission of after-hours emergency CT scans 5 .…”

Video-capture teleradiology for the after-hours reading of computerized tomography scans

et al. 2000

We evaluated the after-hours support that radiologists could provide from their homes to an urban hospital for reading emergency computerized tomography (CT) scans. During a six-month study period, 36 CT scans were acquired using a video-capture card in a PC and transmitted via an ordinary telephone line. The teleradiology interpretation and the formal report (from the hard copy) were compared with a reference or gold standard interpretation made by a radiologist and an emergency physician for 31 of the 36 cases. In comparison with the gold standard, there were 26 correct diagnoses by teleradiology (84%) and five incorrect (16%). Head CT scans accounted for 74% of the transmitted scans and all five of the cases with discrepant diagnoses. The cause of the single clinically relevant discrepancy was found to be unrelated to the use of teleradiology. In comparison with the formal report, the accuracy of the teleradiologist was not significantly different for all categories combined or for head CT scans alone. Video-capture technology provided a reliable means of transmitting CT scans for after-hours interpretation in emergency cases.
