Implementation Science Workshop 2024
Building capacity for the use of implementation science. The Principal Investigators of the project; Dr Phindile Shangase from UFS, left, and Dr Lebogang Mogongoa from the Central University of Technology, with Dr Shalini Ahuja from King’s College London, centre, who facilitated the workshops.

The Division of Public Health at the University of the Free State (UFS) together with the Central University of Technology (CUT), held a successful workshop (first phase) for their project: Capacity building for the use of implementation science in various typologies in low- and middle-income countries for the prevention and/or management of the quadruple burden of disease.

According to the National Institute for Health as well as the World Health Organisation, implementation science supports innovative approaches to identifying, understanding, and overcoming barriers to the adoption, adaptation, integration, scale-up and sustainability of evidence-based interventions, tools, policies, and guidelines. Implementation research therefore pertains to gathering and analysing implementation evidence of effectiveness that determines if the intervention works in real-world circumstances.

The Principal Investigator at UFS is Dr Phindile Shangase from the Division of Public Health, supported by colleagues in the Division, as well as the CUT team, led by Dr Lebogang Mogongoa. The first phase of the project took place from 14-17 October 2024 with the first two days held at UFS.

In this co-funded project, UFS and CUT engage in partnership capacity building for academics and postgraduate students. At the UFS, the project is funded by the Office of the Deputy Vice-Chancellor: Research and Internationalisation and resulted from the CUT and UFS Joint Research Programme Research Grant 9th Call.

Contributing to evidence-based policies and practices

Dr Shangase says the workshops of this project were well attended by academics, researchers, postgraduate and postdoctoral students from different disciplines, and community organisations, including programme managers, as well as clinicians from the Department of Health. Other stakeholders and international students who could not travel for face-to-face interactions attended live on UFS YouTube.

Workshops were facilitated by Dr Shalini Ahuja from King’s College, London, who is an international expert and experienced in this field through engaging in research as well as field facilitation in various low- and middle-income countries.

Says Dr Shangase: “Implementation science is the study of methods and strategies to promote the systematic uptake of research findings. It contributes to evidence-based policies and practices and ensures that they are implemented effectively to achieve their intended outcomes, through the identification of barriers and facilitators to implementation. These strategies can therefore be integrated effectively into routine practice in healthcare, public health, and other fields.

“Reviewed studies indicate that the effectiveness of implementation research is noted in the identification and investigation of factors that address disparities in healthcare delivery and outcomes, including those within the health systems and in the population. In simple terms, the goal of implementation science is to understand how and why some interventions succeed while others fail, and to identify the best ways to integrate research-backed interventions into real-world settings for maximum impact and to ensure they continue to be used and remain effective over time,” says Dr Shangase.

Purpose of project

According to her, in the context of South Africa, implementation science has potential to assist in addressing the quadruple burden of disease which comprise of these colliding epidemics: maternal, newborn and child health; HIV/AIDS and tuberculosis (TB); non-communicable diseases (e.g. cardiovascular diseases, chronic respiratory diseases, cancers, and diabetes); and violence and injury.

The purpose of this project, explains Dr Shangase, is to capacitate academics and postgraduate students at the UFS and CUT as well as community stakeholders with knowledge and skills regarding the processes and factors involved in the successful integration of evidence-based public health improvement interventions into routine practice and policy.

“Implementation science offers a strategic, data-driven approach for South Africa, especially in addressing the country’s unique and complex healthcare challenges. These advantages stem from its focus on translating evidence-based interventions into real-world practice, addressing the quadruple burden of disease and helping overcome systemic obstacles to effective healthcare delivery.

“These advantages make implementation science a vital tool for improving health outcomes and achieving sustainable public health progress in South Africa.”

The next phase of this project is expected to be more innovative and takes place between February and March in 2025 with the inclusion of a multistakeholder team.

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
