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.

“This rating will motivate me to do more research, to improve outcomes, and to aim for a higher C-rating.” This was the response of Dr Jay le Roux, who was recently graded as an Y2-rated researcher by the National Research Foundation (NRF).

Dr Le Roux, senior lecturer in the Department of Geography at the University of the Free State (UFS), is one of 31 new NRF-rated researchers at the UFS. “This grading will make it possible to focus on more specific research during field research and to come in contact with other experts. Researchers are graded on their potential or contribution in their respective fields,” he said.

Research assess different techniques
His research on water erosion risk in South Africa (SA) is a methodological framework with three hierarchal levels presented. It was done in collaboration with the University of Pretoria (UP), Water Research Commission, Department of Agriculture, Forestry and Fisheries, and recently Rhodes University and the Department of Environmental Affairs. Dr Le Roux was registered for 5 years at UP, while working full-time for the Agricultural Research Council – Institute for Soil, Climate and Water (ARC-ISCW).

Water erosion risk assessment in South Africa: towards a methodological framework
, illustrates the most feasible erosion assessment techniques and input datasets that can be used to map water erosion features in SA. It also emphasises the simplicity required for application at a regional scale, with proper incorporation of the most important erosion-causal factors.

The main feature that distinguishes this approach from previous studies is the fact that this study interprets erosion features as individual sediment sources. Modelling the sediment yield contribution from gully erosion (also known as dongas) with emphasis on connectivity and sediment transport, can be considered as an important step towards the assessment of sediment produce at regional scale. 
 
Dams a pivotal element in river networks

Soil is an important, but limited natural resource in SA. Soil erosion not only involves loss of fertile topsoil and reduction of soil productivity, but is also coupled with serious off-site impacts related to increased mobilisation of sediment and delivery to rivers.

The siltation of dams is a big problem in SA, especially dams that are located in eroded catchment areas. Dr Le Roux recently developed a model to assess sediment yield contribution from gully erosion at a large catchment scale. “The Mzimvubu River Catchment is the only large river network in SA on record without a dam.” The flow and sediment yield in the catchment made it possible to estimate dam life expectancies on between 43 and 55 years for future dams in the area.
 
Future model to assess soil erosion
“I plan to finalise a soil erosion model that will determine the sediment yield of gully erosion on a bigger scale.” It will be useful to determine the lifespan of dams where gully erosion is a big problem. Two of his PhD students are currently working on project proposals to assess soil erosion with the help of remote sensing techniques.
