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

14 December 2022 | Story André Damons | Photo André Damons

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.”

Ford foundation funds higher education redesign

2005-06-23

The Ford Foundation has pledged a grant of almost R280 000 for redesigning higher education delivery at three campuses in the Free State.

According to Prof Magda Fourie, Vice-Rector: Academic Planning at the University of the Free State (UFS), the three campuses that will be affected by the strategic reconfiguration of higher education delivery are the Qwaqwa campus at Phuthaditjhaba and the Vista campus of the UFS in Bloemfontein and the Welkom campus of the Central University of Technology (CUT).

Prof Fourie says the three campuses were all affected by the restructuring of higher education, in line with the National Plan for Higher Education.

The Qwaqwa campus of the UFS that was part of the former University of the North was incorporated into the UFS in January 2003. Likewise the Bloemfontein campus of the former Vista University was incorporated into the UFS in January 2004.

The Welkom campus of the CUT was also part of the former Vista University and was incorporated into the CUT in January 2004.

“These incorporations pose a challenge in that we have to think creatively about the best ways of using these three campuses to service the higher education, training, skills development and human resource needs of the Free State,” Prof Fourie said.

“The grant from the Ford Foundation will primarily be used to draw up strategic funding proposals for the three campuses. The Qwaqwa campus of the UFS is a priority to us given the poverty and unemployment in a largely rural area of the Free State,” said Prof Fourie.

“A detailed consultation process will be undertaken in the Qwaqwa campus sub-region which will hopefully result in a comprehensive and a coherent suite of higher education activities being established on this campus,” said Prof Fourie.

“It is envisaged that the Qwaqwa campus will become a centre of excellence in the area of rural development. This vision is based on a focused integration of the core functions of a university – teaching, research, and community service – around the issue of rural development,” said Prof Fourie.

Prof Fourie said that various educational offerings including among others short courses, bridging and foundation programmes, and degrees could be offered, with a particular focus on providing courses of relevance to students from the local rural community and students from elsewhere with an interest in focusing on rural development studies.

She said the redesign of the three affected campuses is being managed as a project of the Free State Higher Education Consortium (FSHEC) consisting of all the higher education institutions operating in the Free State.

“The aim of the project is to establish how the Qwaqwa and Vista campuses of the UFS and the Welkom campus of the CUT can be used effectively to meet regional education and training needs, to serve the strategic priorities of the two higher education institutions and contribute to the sustainable development and poverty alleviation of the region,” she said.

The planning for the Vista campus of the UFS is still in an early stage. “We are looking at the possibility of developing this campus into a hub of education and training opportunities for Bloemfontein and Free State region. Further plans will be communicated later in the year,” said Prof Fourie.
