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.”

Intervarsity postponed to 2013

2012-03-08

The annual Intervarsity between the Universities of the Free State and North-West (NWU), which traditionally takes place in the third term, has been postponed to 2013.

The Intervarsity between the UFS and NWU is an illustrious event that has already reached the special milestone of celebrating a 70-year Intervarsity tradition. The UFS/NWU Intervarsity is also known as one of the most reckoned events on the local and national sports and student calendars, and it is widely supported.

Representatives from both universities could for a variety of reasons not decide on a date which suited both universities.

The respective Intervarsity committees and senior managers of both universities have also taken the interests of the respective university communities and alumni of the institutions into account and have decided to postpone the 70^th-year celebration of Intervarsity by a year in order to be able to celebrate the milestone properly.

The UFS would have received the NWU in Bloemfontein this year and will therefore host the 70-year celebrations of the event next year as well.

Mr Rudi Buys, Dean: Student Affairs at the UFS has expressed his gratitude for the fact that both universities are committed to a special celebration of the Intervarsity tradition in 2013.

“The celebration of the 70^th Intervarsity between the two institutions will be an important milestone to commemorate decades of friendship, collaboration and healthy competition. Therefore we welcome this opportunity to plan a bigger and better programme for 2013,” he said.

The UFS-NWU 70-YEAR Intervarsity firstly aims to establish the programme as a proud example for both universities, where students and staff can pit their strengths against one another in a healthy manner.

The aim is to extend Intervarsity to various sections of the respective university communities to enable more students to participate. For instance, more sports codes will be added to the traditional competition on the rugby, soccer, netball and hockey fields, whilst various events focusing on arts and culture, i.e. choral singing and debating competitions, as well as dialogue between student leaders, will take place as part of the programme. All campuses of the two universities will participate in the programmes.

Students are even investigating the possibility of electronic competitions such as on-line games as part of the Intervarsity

During the Intervarsity last year, several new possibilities were already tested to ensure that the 70^th anniversary would be a huge success.

The Central Intervarsity Committee of the UFS has decided to replace the Intervarsity 2012 programme with an INTRA-varsity programme between its respective campuses. For this occasion, various sports, arts and culture, and leadership events between the Bloemfontein and Qwaqwa Campuses are planned, and the Central University of Technology might be invited as well to participate as guests in some programmes.
