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.”

UFS experimental farm to be redesigned as a training facility

The Faculty of Natural and Agricultural Sciences of the University of the Free State will soon sign a tri-partite cooperation agreement with the National African Farmers Union (NAFU) and the Mangaung Local Municipality with the aim of providing training and mentorship to small-scale and emerging farmers, including those recently settled under the on-going land redistribution programme.

The agreement is part of the Faculty’s strategic plan to support the on-going reform process in the country, of which Black Economic Empowerment in Agriculture (Agri-BEE) is an important part. The Free State Provincial Department of Agriculture is also actively supporting this initiative.

Under the plan, the Faculty is redesigning its experimental farm, located about 12 kilometers south of Bloemfontein, as a training facility to build up skills in among others broiler and egg production, dairy farming, animal husbandry, piggery, sheep and goat production. The idea is to introduce a comprehensive package that empowers the small and emerging farmers and the local communities adjoining the farms through simultaneous investments in research, extension, and practical agricultural training.

Learnerships are also being drawn up to provide productive skills in order to contribute to addressing the national skills gap and enhancing opportunities for both self and wage employment.

The residents of the adjoining informal settlement known as Mangaung Phase II where unemployment is currently at extremely high levels are primary targets of this component of the project. The Faculty intends for this project to service the farming communities of the Free State Province and gradually spread to other Provinces in the country.

Having recognised this training programme as a potential instrument for achieving “a united and prosperous agricultural sector”, the Free State Legislature has shown considerable interest in the programme.

Following a preparatory visit to the farms by the Agriculture Committee of the Free State Legislature a request was made to the Faculty to host a larger visit by the Legislative Committees of the Free State, North West and Eastern Cape Provincial Legislatures on Monday 25 October 2004 and present details of the training programme.

The President of NAFU in the Free State Province, Mr Nox Nonkonyana, the Dean of the Faculty of Natural and Agricultural Sciences, Prof Herman van Schalkwyk, the Chair of the Mangaung Municipal Portfolio for Agriculture and Rural Development, Councilor Thami Stander, and the Chairperson of the Free State Legislative Committee on Agriculture, Mr M Nketu, will address the Legislators during the occasion.
