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.”

New projects will enhance the infrastructure on our campuses

A new entrance to the Main Campus, a high-performance centre, commercial gymnasium, rock-climbing wall, memorial garden for women and a botanical garden are but a few of the number of building and renovation projects that will take place at the Main Campus of the University of the Free State (UFS) in Bloemfontein. A number of projects are also being done on the Qwaqwa Campus.

On the Main Campus the entrance in Nelson Mandela Avenue is being adapted to match the university’s new corporative identity which was introduced last week. This project will be completed at the end of March 2011,

The creation of an environment conducive to the development of its students in the field of teaching, learning and research, as well as sports and culture is one of the main reasons why the UFS is renovating existing buildings and developing new infrastructure.

With the construction of a high-performance centre and commercial gymnasium, the university wants to create a work environment for its staff that will not only contribute to the cultivation of maximum work performance, but also to staff wellness. The centre with its foyer and administrative offices will furthermore consist of a health desk, university sports institute, sports sales, a spinning and aerobic centre, and dressing rooms. The total area will extend over 2114 m² and the construction will take approximately 18 months. This development will take place on the western side of the university’s Main Campus, directly opposite the Furstenburg Gate and next to the new student housing.

The UFS is also progressing well with other building projects which commenced last year. One of the projects is a new Education Building which is being constructed opposite the UFS Sasol Library. Upon completion this building will be used for the training of maths and science teachers in the Foundation Phase. It will include three classrooms for 100 students each and an auditorium for 225 students as well as an office block. The auditorium will also be used as a classroom. The building has been designed according to environmentally friendly principles to save water and use power effectively. It should be completed this year.

Planning for the construction of more student accommodation on the Main Campus as well as the Qwaqwa Campus is already well underway. On the Qwaqwa Campus, a residence with 200 beds is being constructed. This also includes a computer laboratory. According to the planning, this residence should be completed by the end of the first semester in 2011. Furthermore, four residences will be constructed on the Main Campus. These residences are in the planning phase.

In order to place technology within reach of Kovsie students and thereby empowering them, computer laboratories were installed at the respective residences. The computer laboratories will eventually make provision for approximately185 computers for student use. Proper security is also planned to safeguard the equipment.

Work to a new building for the Faculty of Health Sciences is also proceeding rapidly on the site where the vehicle pool and Hertz were previously used. This will include a lecture hall for 200 students, five venues for 100 students each, as well as offices. Students from the School for Medicine and Occupational Therapy will make use of these facilities.

The new building for the Faculty of Economic and Management Sciences between the Flippie Groenewoud Building and the Wynand Mouton Theatre is also coming along nicely.

On the university’s Qwaqwa Campus a new Education building is being constructed. This building will include a lecturing hall with 100 seats, four 50-seat classrooms, six offices, ablution facilities, a biology and science laboratory, as well as an information technology laboratory for 60 students.

In the meantime, existing buildings are being renovated on all the campuses. This includes, amongst others, improvements to the Architecture Building, the Biotechnology Building and the quarters for service workers on the Main Campus. Other improvements that have already been completed include the renovation of the Odeion’s foyer and the Callie Human Centre.

In future, students, staff and visitors to the UFS can also look forward to a rock-climbing wall at the Student Centre on the Thakaneng Bridge, a memorial park for women, residential accommodation within a sports environment, and a botanical garden.
