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.”

Salary adjustment of 7,5%

The University of the Free State’s (UFS) management and trade unions have agreed on a general salary adjustment of 7,5% for 2012.
 
The negotiating parties agreed that adjustments could vary proportionally from a minimum of 7,3% to a maximum of 8,5%, depending on the government subsidy and the model forecasts.
 
The service benefits of staff will be adjusted to 9,82% for 2012. This is according to the estimated government subsidy that will be received in 2012.
 

UVPERSU and NEHAWU sign
 
The agreement was signed (today) Tuesday 8 November 2011 by representatives of the university’s senior leadership and the trade unions UVPERSU and NEHAWU.
 

R2 500 bonus
 
An additional once-off, non-pensionable bonus of R2 500 will also be paid to staff with their December 2011 salary payment. The bonus will be paid to all staff members who were in the employment of the university on UFS conditions of service on 31 December 2011 and who assumed duties before 1 October 2011. The bonus is payable in recognition of the role played by staff during the year to promote the UFS as a university of excellence and as confirmation of the role and effectiveness of the remuneration model.
 
It is the intention to pass the maximum benefit possible on to staff without exceeding the limits of financial sustainability of the institution. For this reason, the negotiating parties reaffirmed their commitment to the Multiple-year, Income-related Remuneration Improvement Model used as a framework for negotiations. The model and its applications are unique and have as a point of departure that the UFS must be and remains financially sustainable. 
 
 
Capacity building and structural adjustments
 
Agreement was reached that 1,54% will be allocated for growth in capacity building to ensure that provision is made for the growth of the UFS over the last few years. A further 0,78% will be allocated to structural adjustments.
 
Agreement about additional matters such as funeral loans was also reached.
 
“The Mutual Forum is particularly pleased that a general salary adjustment of 7,5 % could be negotiated for 2012. Taken into account the world financial downturn, marked cuts in university subsidies and the growth of the university, this is a remarkable achievement,” says Prof. Johan Grobbelaar, Chairperson of the Mutual Negotiation Forum. 
 

Increase for Professors, Deputy and Assistant Directors
 
According to Prof. Grobbelaar the Mutual Forum is also pleased that Professors and Deputy and Assistant Directors will benefit from the structural adjustments. These increases will align the positions with the median of the higher education market. The 1,54% allocated for growth will ensure that appointments can be made where the needs are the highest. The special year-end bonus of R2 500 is an early Christmas gift and implies that the employees in lower salary categories receive an effective increase of almost 9,5 %.
 
“The UFS is in a unique position when it comes to salary negotiations, because the funding model developed more than a decade ago, has stood the test of time and ensured that the staff receive the maximum possible benefits. Of particular note is the fact that the two majority unions (UVPERSU and NEHAWU) work together. The mutual trust between the unions and management is an example of how large organisations can function to reach specific goals and staff harmony,” says Prof. Grobbelaar. 

The implementation date for the salary adjustment is 1 January 2012. The adjustment will be calculated on the total remuneration package.
