A new Cardiac Simulation laboratory will be opened and hosted within the School of Biomedical Sciences’ Clinical Simulation and Skills Unit, at the University of the Free State’s Bloemfontein Campus. The new laboratory is a result of a partnership between Medtronic and UFS. 

The new laboratory will be used to enhance training for cardiothoracic, cardiology, vascular surgery, anaesthesiology and multiprofessional teams   such as doctors, nurses and allied health professionals. The establishment of the laboratory will be made possible by the generous provision of equipment for the establishment and operation of the Cardiac Simulation laboratory by Medtronic.  

Prioritising of patients at the heart of collaboration 

The development of a Cardiac Simulation laboratory at the UFS will not only benefit the training of specialists in various fields of specialisation but will also improve patient safety and reduce complication and mortality rates. The UFS is proud to be part of this initiative to train healthcare professionals to the benefit of the patients.

The Medtronic and UFS contract signing was attended by key stakeholders who included Prof Francis Smit: Head of Cardiothoracic Surgery; Prof Mathys Labuschagne: Head of the Clinical Simulation and Skills Unit; Prof Gert van Zyl: UFS Dean of the Faculty of Health Sciences and Prof Francis Petersen: UFS Rector and Vice-Chancellor. In attendance from Medtronic were Dania Choucair: Medtronic Director Clinical Research and Medical Education; Peter Fuller: Medtronic Country Director; Zampieri Luigi: Business Director   Cardiovascular Group; and Eline Visser: Business Manager   Structural Heart.

The Cardiac Simulation laboratory will make use of part task trainers, medium- and high- fidelity simulation as well as virtual-reality simulation to develop integrated interdisciplinary simulation programmes. These programmes are essential for proficiency development through deliberate practice and should become a statutory requirement for future trainees.

Objective and improved quality of training  

Standard cardiothoracic surgical training programmes are still based on the apprentice model. It implies that registrars in all programmes will attain surgical competency in addition to theoretical training fulfilling minimum statutory requirements for licensing and independent practice. It is highly dependent on surgical volumes, attitude of trainers and perceived surgical ability of the trainee. At best, it produces a mixed bag of competency levels. 

Well-designed integrated interdisciplinary simulation programmes offer an alternative that allows for deliberate practice in an organised step-wise progression model, with inbuilt assessment and feedback systems. This allows for proficiency training rather than competency training in which clear objectives can be met.

The UFS cardiothoracic programme is being designed as a hub and spoke model for South Africa and sub-Saharan Africa, combining distance learning with an onsite high-fidelity simulation and assessment centre. Off-site training in crew resource management or CRM (which addresses communication, decision-making, team-building and maintenance, workload management and situational awareness management), educational theory, surgical theory and basic bench model simulation will be provided. 

Multidisciplinary streams of knowledge 
According to Profs Francis Smit and Mathys Labuschagne, the role of simulation is a dynamic process of continuous movement between theory, simulation and clinical exposure.  “We strive to create an environment where there is free flow between these different components. Registrars and students come from different educational and cultural backgrounds in South Africa and Sub-Saharan Africa and by allowing deliberate practice for students with different needs to practice in their own time is contributing tremendously to students’ individual outcomes and development in the specialty.” 

This dynamic fulfils the needs of students with different competency levels and previous clinical exposure. Debriefing and formative assessment per session are pre-requisites for attending high-fidelity and virtual-reality simulation sessions at the Cardiac Simulation laboratory, because this kind of feedback contributes to the clinical and surgical development as well as inter-professional collaboration of the trainees.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
