Research and Teaching at the Centre for Online Health
The Centre for Online Health (COH) is a university research centre in Queensland, closely linked with (and located in) a tertiary hospital. Research at the COH is directed at the development of new models of healthcare delivery, models that are applicable in Australia and other countries. That is, models of healthcare delivery which are feasible, safe, clinically useful, cost-effective and sustainable. To achieve these goals means conducting clinical research trials. Thus the focus of the work at the COH is on clinical trials, not on technology development. The COH is responsible for a broad range of collaborative projects which explore and evaluate innovative methods of providing clinical services in metropolitan and regional environments, including telemedicine, health information systems and health education. Current research work can be divided into real-time and non-real-time applications
Twenty years of telemedicine in chronic disease management – an evidence synthesis
A literature review was conducted to obtain a high-level view of the value of telemedicine in the management of five common chronic diseases (asthma, COPD, diabetes, heart failure, hypertension). A total of 141 randomised controlled trials (RCTs) was identified, in which 148 telemedicine interventions of various kinds had been tested in a total of 37,695 patients. The value of each intervention was categorised in terms of the outcomes specified by the investigators in that trial, i.e. no attempt was made to extract a common outcome from all studies, as would be required for a conventional meta-analysis. Summarizing the value of these interventions shows, first, that most studies have reported positive effects (n = 108), and almost none have reported negative effects (n = 2). This suggests publication bias. Second, there were no significant differences between the chronic diseases, i.e. telemedicine seems equally effective (or ineffective) in the diseases studied. Third, most studies have been relatively short-term (median duration 6 months). It seems unlikely that in a chronic disease, any intervention can have much effect unless applied for a long period. Finally, there have been very few studies of cost-effectiveness. Thus the evidence base for the value of telemedicine in managing chronic diseases is on the whole weak and contradictory
Adoption of routine telemedicine in Norwegian hospitals: progress over 5 years
Published version. Source at https://doi.org/10.1186/s12913-016-1743-5 . License CC BY 4.0.Background: Although Norway is well known for its early use of telemedicine to provide services for people in
rural and remote areas in the Arctic, little is known about the pace of telemedicine adoption in Norway. The aim of
the present study was to explore the statewide implementation of telemedicine in Norwegian hospitals over time,
and analyse its adoption and level of use.
Methods: Data on outpatient visits and telemedicine consultations delivered by Norwegian hospitals from 2009 to
2013 were collected from the national health registry. Data were stratified by health region, hospital, year, and
clinical specialty.
Results: All four health regions used telemedicine, i.e. there was 100 % adoption at the regional level. The use of
routine telemedicine differed between health regions, and telemedicine appeared to be used mostly in the regions
of lower centrality and population density, such as Northern Norway. Only Central Norway seemed to be atypical.
Twenty-one out of 28 hospitals reported using telemedicine, i.e. there was 75 % adoption at the hospital level.
Neurosurgery and rehabilitation were the clinical specialties where telemedicine was used most frequently. Despite
the growing trend and the high adoption, the relative use of telemedicine compared to that of outpatient visits
was low.
Conclusions: Adoption of telemedicine is Norway was high, with all the health regions and most of the hospitals
reporting using telemedicine. The use of telemedicine appeared to increase over the 5-year study period. However,
the proportion of telemedicine consultations relative to the number of outpatient visits was low. The use of
telemedicine in Norway was low in comparison with that reported in large-scale telemedicine networks in other
countries. To facilitate future comparisons, data on adoption and utilisation over time should be reported routinely
by statewide or network-based telemedicine service
Adoption of telemedicine: from pilot stage to routine delivery
<p>Abstract</p> <p>Background</p> <p>Today there is much debate about why telemedicine has stalled. Teleradiology is the only widespread telemedicine application. Other telemedicine applications appear to be promising candidates for widespread use, but they remain in the early adoption stage. The objective of this debate paper is to achieve a better understanding of the adoption of telemedicine, to assist those trying to move applications from pilot stage to routine delivery.</p> <p>Discussion</p> <p>We have investigated the reasons why telemedicine has stalled by focusing on two, high-level topics: 1) the process of adoption of telemedicine in comparison with other technologies; and 2) the factors involved in the widespread adoption of telemedicine. For each topic, we have formulated hypotheses. First, the advantages for users are the crucial determinant of the speed of adoption of technology in healthcare. Second, the adoption of telemedicine is similar to that of other health technologies and follows an S-shaped logistic growth curve. Third, evidence of cost-effectiveness is a necessary but not sufficient condition for the widespread adoption of telemedicine. Fourth, personal incentives for the health professionals involved in service provision are needed before the widespread adoption of telemedicine will occur.</p> <p>Summary</p> <p>The widespread adoption of telemedicine is a major -- and still underdeveloped -- challenge that needs to be strengthened through new research directions. We have formulated four hypotheses, which are all susceptible to experimental verification. In particular, we believe that data about the adoption of telemedicine should be collected from applications implemented on a large-scale, to test the assumption that the adoption of telemedicine follows an S-shaped growth curve. This will lead to a better understanding of the process, which will in turn accelerate the adoption of new telemedicine applications in future. Research is also required to identify suitable financial and professional incentives for potential telemedicine users and understand their importance for widespread adoption.</p
Relationship between the quality of service provided through store-and-forward telemedicine consultations and the difficulty of the cases – implications for long-term quality assurance
Published version. Also available at http://dx.doi.org/10.3389/fpubh.2015.00217We examined the difficulty of telemedicine cases and the quality of the resultant consultation in a mature store-and-forward telemedicine network. A random sample of 10 telemedicine cases was selected from those occurring over a 3-month period (5% of the workload) and they were scored by three experienced observers. Inter-observer agreement on the difficulty scores was poor (Fleiss’s kappa = 0.18) and it was also poor on the consultation quality scores (Fleiss’s kappa = 0.11). Differences between observers were minimized by consensus scoring, and the cases were re-assessed jointly by two observers. Based on the consensus scores, there was a weak negative relation between output quality and case difficulty, i.e., the more difficult cases tended to result in lower quality consultations. However, the effect was non-significant (P = 0.59) and a larger study might be helpful. In the meantime, routine monitoring of telemedicine service quality will continue in the interests of quality assurance. As yet, there is no evidence on which to base a correction for case difficulty
The development of a multilingual tool for facilitating the primary-specialty care interface in low resource settings: the MSF tele-expertise system
In 2009, Médecins Sans Frontières (MSF) started a pilot trial of store-and-forward telemedicine to support field workers. One network was operated in French and one in English; a third, Spanish network was brought into operation in 2012. The three telemedicine pilots were then combined to form a single multilingual tele-expertise system, tailored to support MSF field staff. We conducted a retrospective analysis of all telemedicine cases referred from April 2010 to March 2014. We also carried out a survey of all users in December 2013. A total of 1039 referrals were received from 41 countries, of which 89% were in English, 10% in French, and 1% in Spanish. The cases covered a very wide range of medical and surgical specialties. The median delay in providing the first specialist response to the referrer was 5.3 h (interquartile range 1.8, 16.4). The survey was sent to 294 referrers and 254 specialists. Of these, 224 were considered as active users (41%). Out of the 548 users, 163 (30%) answered the survey. The majority of referrers (79%) reported that the advice received via the system improved their management of the patient. The main concerns raised by referrers and specialists were the lack of support or promotion of system at headquarters' level and the lack of feedback about patient follow-up. Because of the size of the MSF organization, it is clear that there is potential for further organizational adoption
A web-based telemedicine system for low-resource settings 13 years on: insights from referrers and specialists
Background: One way to tackle health inequalities in resource-poor settings is to establish links between doctors and health professionals there and specialists elsewhere using web-based telemedicine. One such system run by the Swinfen Charitable Trust has been in existence for 13 years which is an unusually long time for such systems. Objective: We wanted to gain some insights into whether and how this system might be improved. Methods: We carried out a survey by questionnaire of referrers and specialists over a six months period. Results: During the study period, a total of 111 cases were referred from 35 different practitioners, of whom 24% were not doctors. Survey replies were received concerning 67 cases, a response rate of 61 per cent. Eighty-seven per cent of the responding referrers found the telemedicine advice useful, and 78% were able to follow the advice provided. As a result of the advice received, the diagnosis was changed in 22% of all cases and confirmed in a further 18 per cent. Patient management was changed in 33 per cent. There was no substantial difference between doctors and non-doctors. During the study period, the 111 cases were responded to by 148 specialists, from whom 108 replies to the questionnaire were received, a response rate of 73 per cent. About half of the specialists (47%) felt that their advice had improved the management of the patients. There were 62 cases where it was possible to match up the opinions of the referrer and the consultants about the value of a specific teleconsultation. In 34 cases (55%) the referrers and specialists agreed about the value. However, in 28 cases (45%) they did not: specialists markedly underestimated the value of a consultation compared to referrers. Both referrers and specialist were extremely positive about the system which appears to be working well. Minor changes such as a clearer referral template and an improved web interface for specialists may improve it
Experience with quality assurance in two store-and-forward telemedicine networks
Published version. Also available at http://dx.doi.org/10.3389/fpubh.2015.00261Despite the increasing use of telemedicine around the world, little has been done to incorporate quality assurance (QA) into these operations. The purpose of the present study was to examine the feasibility of QA in store-and-forward teleconsulting using a previously published framework. During a 2-year study period, we examined the feasibility of using QA tools in two mature telemedicine networks [Médecins Sans Frontières (MSF) and New Zealand Teledermatology (NZT)]. The tools included performance reporting to assess trends, automated follow-up of patients to obtain outcomes data, automated surveying of referrers to obtain user feedback, and retrospective assessment of randomly selected cases to assess quality. In addition, the senior case coordinators in each network were responsible for identifying potential adverse events from email reports received from users. During the study period, there were 149 responses to the patient follow-up questions relating to the 1241 MSF cases (i.e., 12% of cases), and there were 271 responses to the follow-up questions relating to the 639 NZT cases (i.e., 42% of cases). The collection of user feedback reports was combined with the collection of patient follow-up data, thus producing the same response rates. The outcomes data suggested that the telemedicine advice proved useful for the referring doctor in the majority of cases and was likely to benefit the patient. The user feedback was overwhelmingly positive, over 90% of referrers in the two networks finding the advice received to be of educational benefit. The feedback also suggested that the teleconsultation had provided cost savings in about 20% of cases, either to the patient/family, or to the hospital/clinic treating the patient. Various problems were detected by regular monitoring, and certain adverse events were identified from email reports by the users. A single aberrant quality reading was detected by using a process control chart. The present study demonstrates that a QA program is feasible in store-and-forward telemedicine, and shows that it was useful in two different networks, because certain problems were detected (and then solved) that would not have been identified until much later. It seems likely that QA could be used much more widely in telemedicine generally to benefit patient care
Teledermatology in low-resource settings: the MSF experience with a multilingual tele-experise platform
Introduction: In 2010, Médecins Sans Frontières (MSF) launched a tele-expertise system to improve the access to specialized clinical support for its field health workers. Among medical specialties, dermatology is the second most commonly requested type of tele-expertise. The aim of the present study was to review all MSF teledermatology cases in the first 4 years of operation. Our hypothesis was that the review would enable the identification of key areas for improvement in the current MSF teledermatology system. Methods: We carried out a retrospective analysis of all dermatology cases referred by MSF field doctors through the MSF platform from April 2010 until February 2014. We conducted a quantitative and qualitative analysis based on a survey sent to all referrers and specialists involved in these cases. Results: A total of 65 clinical cases were recorded by the system and 26 experts were involved in case management. The median delay in providing the first specialist response was 10.2 h (IQR 3.7–21.1). The median delay in allocating a new case was 0.96 h (IQR 0.26–3.05). The three main countries of case origin were South Sudan (29%), Ethiopia (12%), and Democratic Republic of Congo (10%). The most common topics treated were infectious diseases (46%), inflammatory diseases (25%), and genetic diseases (14%). One-third of users completed the survey. The two main issues raised by specialists and/or referrers were the lack of feedback about patient follow-up and the insufficient quality of clinical details and information supplied by referrers. Discussion: The system clearly delivered a useful service to referrers because the workload rose steadily during the 4-year study period. Nonetheless, user surveys and retrospective analysis suggest that the MSF teledermatology system can be improved by providing guidance on best practice, using pre-filled referral forms, following-up the cases after teleconsultation, and establishing standards for clinical photography
Long-term exercise maintenance in COPD via telerehabilitation: a two-year pilot study
Submitted manuscript version. Published version available at https://doi.org/10.1177/1357633X15625545. Introduction - Pulmonary rehabilitation (PR) is an integral part of the management of chronic obstructive pulmonary disease
(COPD). However, many patients do not access or complete PR, and long-term exercise maintenance has been difficult to
achieve after PR. This study aimed to investigate feasibility, long-term exercise maintenance, clinical effects, quality of life and use
of hospital resources of a telerehabilitation intervention.
Methods - Ten patients with COPD were offered a two-year follow-up via telerehabilitation after attending PR. The intervention consisted of home exercise, telemonitoring and self-management via a webpage combined with weekly videoconferencing
sessions. Equipment included a treadmill, a pulse oximeter and a tablet. Data collected at baseline, one year and two years were
six-minute walking distance (6MWD), COPD assessment test (CAT), EuroQol 5 dimensions (EQ-5D), hospitalisations and
outpatient visits.
Results - No dropout occurred. Physical performance, lung capacity, health status and quality of life were all maintained at two
years. At one year, 6MWD improved by a mean of 40 metres from baseline, CAT decreased by four points and EQ visual
analogue scale (EQ VAS) improved by 15.6 points.
Discussion - Long-term exercise maintenance in COPD via telerehabilitation is feasible. Results are encouraging and suggest
that telerehabilitation can prevent deterioration and improve physical performance, health status and quality of life.<p
