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.

UFS first tertiary institution in SA to form association with the Arbinger Institute

The University of the Free State (UFS) has become the first tertiary institution in the country to form an association with the Arbinger Institute in the United States of America (USA).

“The Arbinger Institute is a global management training and consulting firm applying the implications of self-deception and its solutions to all aspects of organisational performance. Our association with this Institute is a major step for the development of leadership in the country,” says Mr Danie Jacobs, Head of the Centre for Business Dynamics at the UFS.

Dr Cobus Pienaar, from the Department of Industrial Psychology at the UFS, is currently the only licensed facilitator to present Arbinger’s work in South Africa. Dr Pienaar presents The Choice and The Choice @ Work programme on behalf of the Centre for Business Dynamics, under the banner of the UFS School of Business.

According to Mr Jacobs, the programme has already had successes in South Africa. “Dr Pienaar presented the first programme last year in Bloemfontein and Pretoria to leaders from various companies. The feedback on the application of the programme to the South African business environment was phenomenal,” says Mr Jacobs.

The Arbinger Institute’s change work grows out of the scholarly work of philosopher Terry Warner. With an international team of scholars, Warner has broken new ground in solving the age-old problem of self-deception, or what was originally called “resistance”.

“This phenomenon is at the heart of much organisational failure. It is the reason why many organisational problems seem so intractable at their core – they are in self-deception; they resist solution,” says Mr Jacobs.
