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.”

A time to celebrate: Autumn graduations

2016-04-07

General graduation information
Livestreaming

The first series of graduations for the year are upon us. Graduates from all seven faculties, the Business School, and the School of Open Learning at the University of the Free State (UFS) will be celebrating their academic achievements. A total of 3681 qualifications will be conferred at ceremonies on the Bloemfontein Campus from 12 to 15 April 2016.

Sejakhumo Makhetha, daughter of our Vice-Rector: Student Affairs and External Relations, Dr Choice Makhetha, will be among the graduates receiving BA Governance and Political Transformation degrees. Coincidently, Dr Makhetha obtained her PhD in Political Science in 2003 at the UFS. Sejakhumo Makhetha is currently busy with her postgraduate diploma in the same field.

The four-day celebration symbolises the UFS prerogative as an institution to transform lives by producing leaders of tomorrow. Dr Muavia Gallie, Dr Sello Hatang, Dawie Roodt, and Nikiwe Bikitsha are expected to address these future leaders and guests at these ceremonies.

Addressed by the best

On the guest speaker line-up, we have Dr Gallie, a School and District Turnaround Strategist and education activist, who has been identified as one of the 10 Most Impressive Public Leaders for 2015 by the UFS Vice-Chancellor and Rector, Prof Jonathan Jansen. The former Head of Operations, Human Resources and Information and Communication Technology at the South African Council for Educators (SACE) has had more than 30 years of experience in education.

Dr Gallie and Dr Hatang will address graduates of the Faculties of Education, Health Sciences, Law, and Theology on 12 April 2016. Dr Hatang is the Chief Executive of the Nelson Mandela Foundation. In addition to being a founding member of the Advisory Council of the Council for the Advancement of the South African Constitution, Hatang has had the privilege of serving as the Head of Information Communications, and spokesperson for the South African Human Rights Commission as well as Director: South African History Archive at Wits University.

Dawie Roodt, founder, director, and chief economist of the Efficient Group, will speak at the Faculty of Economic and Management Science ceremony on 14 April 2016. This nationally-renowned economist boasts 30 years of experience in monetary and fiscal policy, and is one of the most referenced authors. In 2013, he published Tax, Lies and Red Tape.

As one of South Africa’s leading journalists, Nikiwe Bikitsha will draw on her 20-year career in radio, television, and journalism to address the Faculty of the Humanities graduates on the final day of graduations. Through her passion for Africa’s economic development and women empowerment, the co-founder and CEO of Amargi Media has been a successful Programme Director for UN, IMF and AU-related events.
