Need to improve the care of seriously ill children leads to PhD

Dr Michael Pienaar 1 — 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.”

The University of the Free State (UFS) and Varsity College this week officially launched a partnership whereby the university’s Faculty of Law will offer a four-year Bachelor of Law qualification through the UFS School of Open Learning on eight Varsity College campuses nationwide. This new degree will be offered as early as 2013.

This is the fulfilment of a dream, said Prof. Johan Henning, Dean of the Faculty of Law at the university. He was one of the speakers at the event that was attended by staff members and management from the, Faculty of Law, the university’s South Campus, Varsity College and ADvTECH.

The UFS Faculty of Law is one of the oldest and most distinguished faculties of law in South Africa, and has a close association with several overseas universities which ensures that the institution is internationally recognised.

“I am very positive and enthusiastic about this new partnership. We want to make this an enriching experience for staff and students from both the university as well as Varsity College,” Prof. Henning said.

The CEO of ADvTECH, Mr Frank Thompson, said he is overjoyed about the project and its potential. Varsity College is a brand of the ADvTECH Group, a JSE listed company invested in human capital.

“This is a new beginning for Varsity College and the UFS. Learning together, the slogan for this project, is very appropriate. We are excited to add new students to the university and Varsity College’s line-up,” Mr Thompson said.

Varsity College is part of the Independent Institute of Education (IIE), the leading provider of private higher education in South Africa. According to Dr Felicity Coughlan, Director of the IIE, the partnership between the IIE and the university is an example of the potential that is inherent in public-private partnerships to increase the range of high quality options available to students.

Prof. Jonathan Jansen, Vice-Chancellor and Rector of the UFS, who also was one of the speakers at this event, said with this partnership, students will get the best of both worlds in accessing higher education.

The Faculty of Law will ensure that students obtain both a thorough grounding in legal theory, as well as a solid practical foundation, and Varsity College, through a strong commitment to innovative teaching and learning, will empower more students to become legal graduates of the highest calibre. Thus, the innovative partnership between the UFS and Varsity College will produce a Bachelor of Law degree that is highly sought after in the legal profession.

This partnership is the first of its kind, paving the way for increased collaboration between public and private tertiary institutions to best serve the education sector and the future of graduates.

“This is what is possible when two dynamic partners like the university and Varsity College come together,” Prof. Jansen said.
