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.

Well-established root system important for sustainable production in semi-arid grasslands

The importance of a well-established root system for sustainable production in the semi-arid grasslands cannot be over-emphasised.

A study of Prof Hennie Snyman from the Department of Animal and Wildlife and Grassland Sciences at the University of the Free State is of the few studies in which soil-water instead of rainfall has been used to estimate above- and below-ground production of semi-arid grasslands. “In the past, plant ecological studies have concentrated largely on above-ground parts of the grassland ecosystem with less emphasis on root growth. This study is, therefore, one of the few done on root dynamics in drier areas,” said Prof Snyman.

The longevity of grass seeds in the soil seed bank is another aspect that is being investigated at present. This information could provide guidelines in grassland restoration.

“Understanding changes in the hydrological characteristics of grassland ecosystems with degradation is essential when making grassland management decisions in arid and semi-arid areas to ensure sustainable animal production. The impact of grassland degradation on productivity, root production, root/shoot ratios, and water-use efficiency has been quantified for the semi-arid grasslands over the last 35 years. Because of the great impact of sustainable management guidelines on land users, this study will be continuing for many years,” said Prof Snyman.

Water-use efficiency (WUE) is defined as the quantity of above- and/or below-ground plant produced over a given period of time per unit of water evapotranspired. Sampling is done from grassland artificially maintained in three different grassland conditions: good, moderate, and poor.

As much as 86, 89 and 94% of the roots for grasslands in good, moderate and poor conditions respectively occur at a depth of less than 300 mm. Root mass is strongly seasonal with the most active growth taking place during March and April. Root mass appears to be greater than above-ground production for these semi-arid areas, with an increase in roots in relation to above-ground production with grassland degradation. The mean monthly root/shoot ratios for grasslands in good, moderate, and poor conditions are 1.16, 1.11, and 1.37 respectively. Grassland degradation lowered above- and below-ground plant production significantly as well as water-use efficiency. The mean WUE (root production included) was 4.79, 3.54 and 2.47 kg ha -1 mm -1 for grasslands in good, moderate, and poor conditions respectively.

These water-use efficiency observations are among the few that also include root production in their calculations.
