- ItemBusiness models for sustained eHealth implementation : lessons from two continents(Computers & Industrial Engineering Conference Proceedings, 2012-07) Van Dyk, Liezl; Wentzel, M. Jobke; Van Limburg, A.H. Maarten; Van Gemert-Pijnen, Lisette; Schutte, Corne S. L.; CIE42 ProceedingsThere is general consensus that Computers and Information Technology have the potential to enhance health systems applications, and many good examples of such applications exist all over the world. Unfortunately, with respect to eHealth and telemedicine, there is much disillusionment and scepticism. This paper describes two models that were developed separately, but had the same purpose, namely to facilitate a holistic approach to the development and implementation of eHealth solutions. The roadmap of the Centre for eHealth Research (CeHRes roadmap) was developed in the Netherlands, and the Telemedicine Maturity Model (TMMM) was developed in South Africa. The purpose of this paper is to analyse the commonalities and differences of these approaches, and to explore how they can be used to complement each other. The first part of this paper comprises of a comparison of these models in terms of origin, research domain and design principles. Case comparisons are then presented to illustrate how these models complement one another.
- ItemClinical-pull approach to telemedicine implementation policies using health informatics in the developing world(IGI Global, 2012-04) Treurnicht, Maria J.; Van Dyk, LiezlENGLISH ABSTRACT: Telemedicine could effectively aid hospital referral systems in bringing specialized care to rural communities. South Africa has identified telemedicine as part of its primary health care strategic plan, but similar to many other developing countries, the successful implementation of telemedicine programs is a daunting challenge. One of the contributing factors is the insufficient evidence that telemedicine is a cost-effective alternative. Furthermore, many telemedicine services are implemented without a thorough needs assessment. Throughout this chapter, the authors investigate the use of medical informatics in quantitative telemedicine needs assessments. A framework is introduced to direct implementation policies towards a proven clinical need rather than pushing technology into practise. This clinical-pull strategy aims to reduce the amount of failed projects, by providing decision support to implement appropriate technologies that have the potential to contribute towards better quality healthcare.
- ItemA decision support system for equipment allocation in a telemedicine referral network(Southern African Institute for Industrial Engineering, 2014-05) Treurnicht, Maria J.; Van Dyk, LiezlTelemedicine applications have had much success in strengthening health systems worldwide. Unfortunately, many systems are implemented without decisions based on proper needs assessments. In South Africa, this ‘technology push’ approach has led to a large amount of equipment standing dormant. It is proposed that the potential of telemedicine be measured prior to implementation, thus ‘pulling’ the technology towards a clinical need. A decision support system is developed that uses health informatics and computational intelligence to determine the need for telemedicine and to allocate equipment in a network of facilities to achieve the best cost benefit. The system facilitates the collection and storage of electronic health record (EHR) data in a data warehouse. A linear programming model is used with a genetic algorithm. The system was developed and tested for the South African public health sector, using data from 27 hospitals in the Western Cape Province. Results have shown that if telemedicine workstations with specific peripheral equipment, as determined by the algorithm, were implemented in the given period, an estimated R8.7 million in referral costs could have been saved for the 27 hospitals. Thus the case study provided evidence for the benefits of implementation in the chosen network of hospitals. This new application of health informatics could provide telemedicine management with a useful tool for making implementation decisions based on evidence. Future work would include the development of similar systems for other markets.
- ItemDevelopment of a maturity model for telemedicine(Southern African Institute for Industrial Engineering, 2012-07) Van Dyk, Liezl; Schutte, Corne S. L.For more than a decade, the South African National Department of Health (DoH) has recognised the potential benefit of information and communication technology (ICT) in the delivery of health care to rural areas. Despite generous funding and proven technology, not many telemedicine systems have proved sustainable after the pilot phase. The purpose of this paper is to develop a maturity model that can be implemented to measure and manage the capability of a health system, for use in the delivery of sustainable health care after the pilot phase of a telemedicine project. The validity of the telemedicine maturity model (TMMM) is tested within the context of the South African public health sector.
- ItemThe development of a telemedicine service maturity model(Stellenbosch : Stellenbosch University, 2013-12) Van Dyk, Liezl; Schutte, C. S. L.; Stellenbosch University. Faculty of Engineering. Dept. of Industrial Engineering.ENGLISH ABSTRACT: A telemedicine service is a healthcare service (-medicine) that is delivered over a distance (tele-). The interest in the potential of telemedicine to increase the quality, accessibility, utilization, e ciency and e ectiveness of healthcare services is fuelled by the rapid development of information and communication technology (ICT) and connectivity. Despite this potential, the success rate of telemedicine services disappoints. Many mistakes in the implementation of telemedicine services are repeated over and over again and best practices are not captured and replicated. This study responds to the need for reference models for the assessment and optimization of telemedicine services in a consistent, systematic and systemic way. Maturity models are reference models that describe typical patterns in the development of organizational capabilities and depict a sequence of stages towards the desired state. Many reference models exist that are applicable to telemedicine services, but none of these provide guidance for the optimization of services, like a maturity model does. Many maturity models exist within a health systems context, but none of these can be applied "as is" to telemedicine services. In this study an iterative top-down design approach is followed to develop a Telemedicine Service Maturity Model (TMSMM). This model facilitates the assessment of a telemedicine service on micro, meso, and macrolevel along all the domains that comprise the telemedicine health system. Sets of capability statements are de ned, which follow each other in a cumulative manner, hence providing a maturation path towards the desired maturity state. These sets of capability statements provide yardsticks according to which quantitative values are allocated to an intangible concept, such as maturity. Once an individual service is assessed, further actions towards the optimization of the service can be derived from these yardsticks. The multidimensional design of the TMSMM, as well as the fact that capability statements facilitate the consistent quanti cation of maturity, makes it possible to analyze the aggregated results of cohort of services. To accomplish this, principles of business intelligence and data warehouse design are applied together with online analytic processing (OLAP) procedures. The TMSMM addresses the previously unful lled need for a reference model to assess and optimize telemedicine services in a consistent, systematic and systemic way. This study spans several academic and professional domains and thereby contributes to the scienti c world of telemedicine and ehealth.
- ItemProve your hypothesis(Stellenbosch : University of Stellenbosch, 2011-09) Wynchank, Sinclair; Van Dyk, Liezl; Fortuin, Jill; ISfTeH Conference (16th : 2011 : Cape Town); South African Telemedicine and eHealth Conference (2nd : 2011 : Cape Town)The Southern African Telemedicine conference has extended its reach in 2011 and now includes eHealth and other relevant areas such as e-Learning, mHealth and innovation. Our partner, ISFTeH, is also hosting its 16th International Telemedicine & eHealth Conference with its SA partners this year. This year’s conference is significant as not only does it have important academic components, but it also has a very strong presence from the government. The government’s role is extremely important as it guides all stakeholders and role players in the future direction of Telemedicine and eHealth. The academic component of the conference ties in closely with the theme ‘prove your hypothesis’. Prove your hypothesis relates to the presentations of research findings in the area of Telemedicine & eHealth. A stringent peer review process was followed and the conference proceeding includes quality abstracts based on sound research methodologies. The research presented in this conference is very valuable as it informs the next stage of the process in solidifying the Telemedicine & mHealth; eHealth environment, which is policy development. South Africans can now look forward to policy development in telemedicine, which will help to move from research to sustainable solutions that will help to ensure that healthcare is delivered in an efficient, effective manner.
