Dr Michael Pienaar, Senior Lecturer and specialist in the UFS Department of Paediatrics and Child Health being presented to the acting Chancellor by his supervisor Prof Stephen Brown.

A lecturer from the University of the Free State (UFS) says the need to improve the care of seriously ill children is a vital part of reducing preventable deaths and diseases, and this led him to investigate the use of artificial neural networks to develop models for the prediction of patient outcomes in children with severe illness. The study was done for his PhD thesis. 

This forms the basis for the PhD thesis of Dr Michael Pienaar, Senior Lecturer and specialist in the UFS Department of Paediatrics and Child Health, called, The Development and Validation of Predictive Models for Paediatric Critical Illness in Children in Central South Africa using Artificial Neural Networks. His thesis reports the development and testing of several machine learning models designed to help healthcare workers identify seriously ill children early in a range of resource-limited settings. Combining a systematic literature search and Delphi technique with clinical data from 1 032 participants, this research led to significant progress towards implementable models for community health workers in clinical practice.

Care for critically ill children is a mission and calling 

Dr Pienaar graduated with a PhD specialising in Paediatrics on Monday (12 December) during the Faculty of Health Sciences’ December graduation ceremony. It took him three years to complete this degree. His supervisor was Prof Stephen Brown, Principal Specialist and Head of the Division of Paediatric Cardiology in the Department of Paediatrics and Child Health in the Faculty of Health Sciences at the UFS. Prof Nicolaas Luwes and Dr EC George were his co-supervisors. 

“I have been working in paediatric critical care since 2019 and see the care of critically ill children as my mission and calling in life. At the outset of the project, I was interested in approaches to complex phenomena and wanted to investigate new methods for tackling these in healthcare. 

“I have been interested in technology since childhood and in collaborating with other disciplines since I joined the university in 2019. Machine learning seemed like a great fit that could incorporate these interests and yield meaningful clinical results,” explains Dr Pienaar the reason why he chose this topic for his thesis.

He hopes that, in time, this work will lead to the implementation of integrated machine learning models to improve care and clinical outcomes for children in South Africa. From a scholarship perspective, he continues, his hope is that this work draws interest to this field in clinical research and encourages a move towards incorporating these new methods, as well as skills in areas such as coding and design in the armamentarium of a new generation of clinicians.

Medicine chooses you

According to Dr Pienaar, he always had broad interests, of which medicine is one. “I am very grateful to have found my way in medicine and am humbled and privileged to be allowed to walk with children and their families on a difficult and important journey. I believe this profession will choose you and put you where you are needed if you give it time and are prepared to listen.”

He describes graduating as a complicated ending to this period of his life and the beginning of a next chapter. He was humbled by the graduation ceremony. 

“It was wonderful to graduate with undergraduates and postgraduates in my profession – I felt great pride and solidarity joining these new colleagues and specialists in taking the oath. I am certainly relieved, proud, excited, and happy. I am also very grateful to the university, my promotors, colleagues, friends, and family for supporting me through this process. I must confess, it is also slightly bittersweet, I loved working on this and do miss it, but look forward to the next exciting project. 

“I would like to thank my Head of Department, Dr (Nomakhuwa) Tabane, my supervisors, my family and friends once again. I would also like to acknowledge and thank the National Research Foundation (NRF) as well as the University of the Free State for their assistance with funding this research.”

UFS plans to improve undergraduate pass rate
2005-01-13

The University of the Free State (UFS) will introduce a new foundation programme this year 2005 in an effort to improve the academic performance of undergraduate students.

According to Mr Francois Marais, Head: Centre for Higher Education Studies and Development (CHESD) at the UFS, the programme will assist students by providing for the development of cognitive and critical thinking skills by means of the integration of appropriate thinking skills (such as creative thinking, decision-making, problem solving, reasoning, and how to learn), into the subject content of university courses.

“The foundation programme will benefit students from disadvantaged school backgrounds and, in future, those whose performance in proficiency tests points to the need for additional development in, for example, language proficiency, mathematical literacy, computer skills and life skills,” says Mr Marais.

Based on their level of achievement in the final Grade 12 examination (Senior Certificate), students will be referred to the foundation programme.

In order to improve students writing and reading abilities for higher education studies, foundation programme students will be offered academic language courses in English and Afrikaans.

Kovsie Counselling will render appropriate services, eg career guidance and support to these students.

The new foundation programme will be implemented in the faculties of Natural and Agricultural Sciences, Economic and Management Science, the Humanities and Law.

The duration for this programme differs from faculty to faculty. In the Faculty of Law it will take five years, while in the faculties of the Humanities, Natural and Agricultural Sciences, and Economic and Management Sciences it will take four years.

The national Department of Education will fund the foundation programme for three years. Funding for such programmes was made available to all higher education institutions in South Africa.

The welcoming function for all new first-year students and their parents will take place on Saturday 15 January 2005 at 11:00 in the Callie Human Centre on the main campus in Bloemfontein.

The registration of first-time entering first-year students who applied before 30 November 2004 to study at the Bloemfontein campus will take place from Monday 17 January 2005 to 21 January 2005 at the Callie Human Centre.

Senior undergraduate students (that is, students entering their second or later year of study) may register from 22 to 29 January 2005.

Postgraduate students, first time entering first year students and other students who applied for admission to the main campus after 30 November 2004 must register at the Callie Human from 31 January 2005 to 4 February 2005.

Due to the limitations placed by government on student numbers, the applications of students who applied late will be regarded as pending and will be processed as places become available.
