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 SIFE is the best in SA!

2004-07-09

The SIFE team celebrates their victory with Jack Shewmaker, founder of SIFE in 1975 and past-president of Walmart in the USA, and Moses Kgosana, Chairman of KPMG SA.

The Students in Free Enterprise (SIFE) team of the University of the Free State competed in the National SIFE championships on Thursday, June 17, 2004 at Ceasar’s Convention Centre in Johannesburg.

Strong competition was experienced from the other ten participant SA universities, e.g. the Universities of the Western Cape, Kwazulu-Natal, Cape Town and RAU, but die UFS SIFE team retained the national championship for the third year running.

The team will now represent South Africa and the University of the Free State in Barcelona, Spain at die SIFE World Cup. The competition will be held from 22 to 24 September 2004.

The presentation team members for the competition were Tsholofelo Tlhomelang, Imameleng Matete, Kenneth Lefa, Kabelo Lephaka, Nadia van Staden, Tshepo Mahloko (Multi-Media), Werner Schmidt (Faculty Advisor). Supporting the presentation team were Lineo Peete, Keketso Ntene, Ruth Morienyane, Motaung Mathaba, Tshireletso Seekoe, Peter Letsoalo, Obakeng Msuthwana, Tshepiso Lebentle, JC Langeveldt and Michelle Stanley.

SIFE is a world-wide non-profit organisation with the express aim of encouraging students to spread their business knowledge - gained in the classroom - to the community, to promote and expand the principles of free enterprise.( www.sife.org )

The criteria by which SIFE-projects are measured are the following:

• How free markets work in the global economy.
• How entrepreneurs succeed by identifying a market need and then profitably producing and marketing a product or service to fill that need.
• The personal entrepreneurial, communications, technology and financial management skills needed to successfully compete.
• Practicing business in an ethical and socially responsible manner that supports the principles of a market economy.
• Measuring the results of projects, utilizing mass media and the Internet, involving non-business majors and utilizing a Business Advisory Board, communicating the program through a written report and verbal presentation.

The UFS’ SIFE-team’s presentation complied with all the above mentioned criteria. SIFE UFS’ education drive stretched from primary school learners, to adults who had been working for thirty years – this diverse group was taught about the free market system and its value in the global village. Business ethics and basic business principles were communicated in a fun and interactive way to learners. High-level business advice was given to entrepreneurs who started new projects, e.g. a brick-maker, and marketing advice were given to existing businesses in need of expansion.
