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.”

Open Day attracts thousands

“It is easier to pass Grade 12 today because we don’t have a standard. However, at the University of the Free State, standards are important.”

This was Prof. Jonathan Jansen, Vice-Chancellor and Rector of the UFS’ message when he addressed a packed Callie Human Centre on the Bloemfontein Campus during this year’s Open Day.

“This university is the jewel of the country. Here at Kovsies we take academic standards seriously. You must know who you are in a place where academic standards are extremely important. Anyone can obtain a degree, but here you can get more than a degree. You get an education,” he said to the more than 5 000 learners and parents from across the country.

“It is not only important that you study here in South Africa, but also in other countries. That is why our students study all over the world. You must think out of your comfort zone, have a big heart, achieve great heights and show everyone that you are a Kovsie.

But, it is not all about studying – it is also about being human and reaching out to others. When you come to this university, you will also do other things that will make you proud of being a Kovsie.

Quality looks for quality. Therefore, work hard and study hard because you need to be at a good university,” he said.

The programme consisted of, among others, a spectacular laser show, a performance by Bobby van Jaarsveld and special messages from DW Bester and Sannah Mokone, Rhodes Scholars currently studying at Oxford University in the United Kingdom.

In a pre-recorded message DW, a Ph.D. student in Mathematical Statistics, encouraged prospective students to work hard and persevere. Sannah, doing a Master’s degree in African Studies, said she believes in the future of the African continent. “I believe in our future students and know you can make it.”

Prof. Jansen also introduced some of the university’s recent student achievers such as Jurie Swart, regional winner of the Corobrik Architectural Student of the Year Award; Farzana Samuel, named by the Association of South African Quantity Surveyors (ASAQS) as the most outstanding student in quantity surveying for 2012; and Sibusiso Tshabalala, one of Google’s Top 10 Young Minds.

Richard Chemaly, President of the Central Student Representative Council (CSRC), said that, by coming to Kovsies, prospective students would become the best person they can be. “We have over 70 student organisations to help you take part in student life activities. So, make use of these opportunities,” he said.

The programme concluded with an introduction to the seven faculties by the respective deans.

The estimated 7 000 prospective students and their parents also had the opportunity to visit faculties and the stalls of residences.
