Dr Michael Pienaar is a lecturer in the University of the Free State’s (UFS) department of Paediatrics and Child Health.

A lecturer from the University of the Free State’s (UFS) department of Paediatrics and Child Health is investigating the use of artificial neural networks to develop models for the prediction of patient outcomes in children with severe illness.

Dr Michael Pienaar, senior lecturer and specialist, is conducting this research as part of his doctoral research and the study deals primarily with the development of models that are designed and calibrated for use in South Africa. These artificial neural networks are computer programs designed to mimic some of the learning characteristics of biological neurons.

The potential applications of models

According to Dr Pienaar these models have traditionally been developed in high-income nations using conventional statistical methods.

“The potential applications of such models in the clinical setting include triage, medical research, guidance of resource allocation and quality control. Having initially begun this research investigating the prediction of mortality outcomes in the paediatric intensive care unit (PICU) I have broadened my scope to patients outside of PICU, seeking to identify children early during their illnesses who are at risk of serious illness requiring PICU,” says Dr Pienaar.

The research up until now has been directed towards the identification of characteristics that are both unique to children with serious illness in South Africa, but also accessible to clinicians in settings where expertise and technical resources are limited.

Research still in the early changes

The research is still in its early stages but next year a series of expert review panels will be held to investigate the selection of variables for the model, after which the collection of clinical data will begin. Once the data has been collected and prepared, a number of candidate models will be developed and evaluated. This should be concluded by the end of 2022.

Says Dr Pienaar: “The need to engage with the rapid proliferation of technology, particularly in the realms of machine learning, mobile technology, automation and the Internet of Things is as great in medical research now as it is in any academic discipline.

“It is critical that research, particularly in South Africa, engage with this in order to take advantage of the opportunities offered and avoid the dangers that go paired with them. Together with the technology as such, it has been essential to pursue this project as an interdisciplinary undertaking involving clinicians, biostatisticians and computer engineers.”

Hope for the research  

Dr Pienaar says he was very fortunate and grateful to be the recipient of a generous interdisciplinary grant from the UFS which has allowed him to procure software and equipment that is critical to this project.

“The hope for this research is that the best performing of these models can be integrated with a mobile application that assists practitioners in a wide range of settings in the identification, treatment and early referral of children at high risk of severe illness. I would like to expand this research project to include other countries in Africa and South America and to use it as a bridge to collaboration with other clinical researchers in the Global South,” says Dr Pienaar.

As an early career researcher, Dr Pienaar hopes that this research can serve as a platform to build a body of research that uses the rapid technological advances of these times together with a wide range of collaborations with other disciplines in the pursuit of better child health.

He concludes by saying that he has had excellent support thus far from his supervisors, Prof Stephen Brown (Faculty of Health Sciences, UFS), Dr Nicolaas Luwes (Faculty of Computer Science and Engineering, Central University of Technology) and Dr Elizabeth George (Medical Research Council Clinical Trials Unit, University College London). I have also been supported by the Robert Frater Institute in the Faculty of Health Sciences.

MBA Programme - Question And Answer Sheet - 27 May 2004
2004-05-27

1. WHAT MUST THE UNIVERSITY OF THE FREE STATE (UFS) DO TO GET FULL ACCREDITATION FOR THE MBA PROGRAMMES?

According to the Council on Higher Education’s (CHE) evaluation, the three MBA programmes of the UFS clearly and significantly contribute to students’ knowledge and skills, are relevant for the workplace, are appropriately resourced and have an appropriate internal and external programme environment. These programmes are the MBA General, the MBA in Health Care Management and the MBA in Entrepreneurship.

What the Council on Higher Education did find, was a few technical and administrative issues that need to be addressed.

This is why the three MBA programmes of the UFS received conditional accreditation – which in itself is a major achievement for the UFS’s School of Management, which was only four years old at the time of the evaluation.

The following breakdown gives one a sense of the mostly administrative nature of the conditions that have to be met before full accreditation is granted by the CHE:

a. A formal forum of stakeholders: The UFS is required to establish a more structured, inclusive process of review of its MBA programmes. This is an administrative formality already in process.

b. A work allocation model: According to the CHE this is required to regulate the workload of the teaching staff, particularly as student numbers grow, rather than via standard management processes as currently done.

c. Contractual agreements with part-time staff: The UFS is required to enter into formal agreements with part-time and contractual staff as all agreements are currently done on an informal and claim-basis. This is an administrative formality already in process.

d. A formal curriculum committee: According to the CHE, the School of Management had realised the need for a structure – other than the current Faculty Board - where all MBA lecturers can deliberate on the MBA programmes, and serve as a channel for faculty input, consultation and decision-making.

e. A system of external moderators: This need was already identified by the UFS and the system is to be implemented as early as July 2004.

f. A compulsory research component: The UFS is required to introduce a research component which will include the development of research skills for the business environment. The UFS management identified this need and has approved such a component - it is to take effect from January 2005. This is an insufficient element lacking in virtually all MBA programmes in South Africa.

g. Support programmes for learners having problems with numeracy: The UFS identified this as a need for academic support among some learners and has already developed such a programme which will be implemented from January 2005.

The majority of these conditions have been satisfied already and few remaining steps will take effect soon. It is for this reason that the UFS is confident that its three MBA programmes will soon receive full accreditation.

2. WHAT ACCREDITATION DOES THE UFS HAVE FOR ITS MBA PROGRAMME?

The UFS’s School of Management received conditional accreditation for its three MBA programmes.

Two levels of accreditation are awarded to tertiary institutions for their MBA programmes, namely full accreditation and conditional accreditation. When a programme does not comply with the minimum requirements regarding a small number of criteria, conditional accreditation is given. This can be rectified during the short or medium term.

3. IS THERE ANYTHING WRONG WITH THE ACADEMIC CORE OF THE UFS’s MBA PROGRAMMES?

No. The UFS is proud of its three MBA programmes’ reputation in the market and the positive feedback it receives from graduandi and their employers.

The MBA programmes of the UFS meet most of the minimum requirements of the evaluation process.

In particular, the key element of ‘teaching and learning’, which relates to the curriculum and content of the MBA programmes, is beyond question. In other words, the core of what is being taught in our MBA programmes is sound.

4. IS THE UFS’s MBA A WORTHWHILE QUALIFICATION?

Yes. Earlier this year, the School of Management – young as it is - was rated by employers as the best smaller business school in South Africa. This was based on a survey conducted by the Professional Management Review and reported in the Sunday Times Business Times, of 25 January 2004.

The UFS is committed to maintaining these high standards of quality, not only through compliance with the requirements of the CHE, but also through implementing its own quality assurance measures.

Another way in which we benchmark the quality of our MBA programmes is through the partnerships we have formed with institutions such as the DePaul University in Chicago and Kansas State University, both in the US, as well as the Robert Schuman University in France.

For this reason the UFS appreciates and supports the work of the CHE and welcomes its specific findings regarding the three MBA programmes.

It is understandable that the MBA review has caused some nervousness – not least among current MBA students throughout the country.

However, one principle that the UFS management is committed to is this: preparing all our students for a world of challenge and change. Without any doubt the MBA programme of the UFS is a solid preparation.
