It was recently discovered that bacteria are capable of growing inside bottles of disinfectants, hand sanitisers and antiseptics. These cleaning products, which are actively used in South African hospitals, are doing more harm than good by contaminating the environment they are designed to clean. Upon testing, some of these contaminated bottles harbouring harmful microorganisms were still actively in use in hospitals and instead of killing microorganisms, the contaminated cleaning solutions were spreading pathogens throughout the hospital with their use. 

This is according to Samantha Mc Carlie from the Department of Microbiology and Biochemistry at the University of the Free State (UFS). She, with her promotor, Prof Robert Bragg, were part of a workshop at the Africa Health Exhibition – the biggest gathering of health care professionals in South Africa and Africa. This was held at Gallagher Estate, Midrand, from 17 to 19 October 2023. 

Increasing mortalities in health-care setting

In a workshop titled: “Developing and sustaining safe health-care environments”, they were part of the main presenting panel, together with Caroline Bilen from the Compass Health Consultancy in Dubai 

Prof Bragg, whose main research is in disease-control, first in the agricultural industry, and now human health, started off the session by highlighting the problems with the increasing mortalities in the health-care setting. He presented data indicating that in the not too distant future, deaths from hospital-acquired infections would be the leading cause of human deaths. “This problem is rapidly growing as most of the pathogens which people contract while in hospital are now resistant to antibiotics, making them very difficult to treat,” he explained.

He used an analogy from San Tzu from the book The Art of War to explain why humankind is losing the war against the microbes. “San Tzu stated that if you know yourself and know your enemy, you will be victorious in every battle. On the other hand, if you do not know yourself or the enemy, you will be defeated in every battle. He pointed out that we do not know the enemy and we do know ourselves (or rather the weapons we have to defeat the enemy) and for this reason we are being defeated,” according to Prof Bragg. 

He continued: “We know the names of the different pathogens causing diseases, but do we really understand them? The answer to that must be ‘no’. A typical example is people are using ethanol-based or chlorine-based products to disinfect and then they wonder why there are increasing problems with Clostridioides difficile infections. If we knew the enemy, we would know that this bacterium producers endospores  and chlorine and ethanol-based disinfectants do not inactivate bacterial endospores, and so will not kill this bacterium,” said Prof Bragg. 

He stated that a major concern for hospitals is that they are currently unaware of whether the disinfectants they are using are effective against the pathogens in their hospital. It is assumed that their cleaning products are working but no testing is being done.

Bacterial resistance to disinfectants

Mc Carlie, in her presentation, highlighted the development of bacterial resistance to disinfectants and why this is important in the health-care setting. She pointed out that the standards for the registration of disinfectant products is based on the use of reference strains of bacteria.

“Bacteria found in hospital environments often exhibit significantly greater resistance to disinfectant compounds compared to the standard strains used for product testing. The presence of these resistant bacteria can result in microbial growth and contamination within containers of disinfectants, hand sanitisers, and antiseptics intended for hospital cleaning purposes. Instead of effectively eliminating microorganisms, these contaminated products inadvertently spread these resilient bacteria throughout the hospital environment, contributing to overall contamination,” said Mc Carlie.

She also discussed the consequences of using incorrectly diluted disinfectant products at concentrations that will not be effective against resilient hospital pathogens. 

Prof Bragg finished the session with a discussion on the solutions to the current problem and highlighted the need for a paradigm shift in medicine. “The current paradigm, since the discovery of antibiotics, has been treatment. As we are entering into a post-antibiotic era, this paradigm of treatment needs to change to one of ‘prevention’. The old saying ‘Prevention is better than cure’ has never been more true.”

He concluded by discussing various options which could be used when focus is placed on biosecurity for the prevention of hospital-acquired infection; including the installation of UV lights, monitoring of the laundry process, correct disinfecting of surfaces, using products with proven efficacy against the pathogens isolated from the different health-care setting and finally, the use of antimicrobial bedside privacy curtains.

The workshop ended with a panel discussion on biosecurity and the efforts needed to reduce the ever-increasing numbers of hospital-acquired infections. It is hoped that the message of this workshop will have a significant impact on the reduction of hospital acquired infections.

Prof Jonathan Jansen bids farewell to Kovsies
2016-08-31

 

Dear Kovsie staff and students

This is my final message to you all.

I wish to use this opportunity for some brief reflections, share a word of gratitude, and convey a sense of the future for our beloved university.

Since the announcement of my departure, I have had more than a dozen breakfasts with mainly students, but also staff, to offer an opportunity for the final sharing of thoughts and, of course, goodbyes. The most common questions asked at those breakfast sessions were the following, with my responses. I repeat them here, since these might also be of interest or concern to you.

What are your proudest achievements?
Two things. The increase in the academic standard for the UFS, both in terms of admission standards and pass rates, but also in relation to the requirements for appointment and promotion especially of professors. This is important because in a globally competitive world, a university stands or falls by the quality of its degrees. And for this you need the best students and the best professors.

What would you do differently, given another chance?
Nothing. I believe that leadership is about doing the best you can with the cards you are dealt in the circumstances in which you are placed. There is no point in second-guessing past decisions. I have always been ambitious as a leader, knowing that most of my goals would be met, and that some would not. That is normal in large and complex organisations, and so, I do not sit around pondering regrets, only remembering with gratitude the things we could achieve together.

What did you learn?
A lot. I learnt that our students have tremendous capacity for greatness both in their academic pursuits but also in their ability to live, and learn, and love together. I have learnt never to underestimate the capacity of our youth to excel in whatever they do. Sometimes I felt I was more ambitious for our students and staff, than they were for themselves. But I have constantly been surprised by the capacity of young students to rise above bitterness and division, and to make great our campus, country, and continent.

I learnt, again, that the overwhelming majority of our staff and students are good people, respectful of each other, and determined to work together to heal our broken past and build a more just society. And I learnt that it is much more fulfilling to build up than to break down, to embrace than to exclude, and to love than to hate.

Were you frustrated with the pace of transformation?
Sometimes, yes. But fortunately I studied educational organisations all my life, mainly schools and universities. Universities are called institutions for a reason, and on century-old sites like the historic Bloemfontein Campus of the University of the Free State, there are core beliefs, values, and practices deeply ingrained in the culture of the place.

Anyone, therefore, who believes that transformation is easy, has obviously never tried to change an old university. It is difficult. You will get blowback. You will get bad press. You will, sadly, lose the support of some people. Some believe the university is changing too fast while others will tell you it is not changing fast enough. As you press for change, you find the university going two steps forward and one step back; in these circumstances, the solemn duty of the leader is simply to ensure that the overall momentum is always forward.

For such a time as this –

I therefore budget for disappointment even as I relish the many changes we have experienced together over the past seven years. If you want to obtain an objective sense of the scale of the changes at the UFS, ask those students and staff who were here in 2009, not those who came recently. They will tell you that we have a very different university, even though we all acknowledge that there is still some distance to travel. Our remarkable story of change is told in the recent Transformation Audit of the UFS, chaired by Prof Barney Pityana; that Audit Report will be released after it is read and studied by the University Council at its November meeting.

At an individual level, I learnt that most campus citizens change quickly and others more slowly, and that one has a duty to constantly push for change, but also to be patient about change. And I learnt that the ideal change retains the best of our past even as we embrace a more just and inclusive future in which all campus citizens feel that the university truly belongs to each and every one of them.

Are you optimistic about the future of our university?

Yes. The UFS is a very well-managed university thanks to the exceptional talent in the management of our finances, human resources and information technology environments. By the end of 2016, we will have record enrolments, from undergraduates to doctoral students, which is good for our future income. We run a tight ship with regard to the university’s finances, and we have greatly improved the academic standard of our qualifications; in this regard, I am very proud of my senior management team, and the talented middle management personnel, and those who make things work at the coalface of our operations.

I am very concerned, however, about future funding of the 26 public universities and the extremely vulnerable situation of at least 10 higher-education institutions. The economy is not growing and the costs of running a modern university are escalating. The delays in government commission reports on tuition fees do not help, and there seems no urgency ‘higher up’ to make the tough decisions.

We have to ensure free education for the poorest students — that is the position of your senior management – but we also need to guarantee the financial sustainability of our universities. The task of the UFS leadership, in this period of uncertainty, is to manage those two expectations as best we can. But this cannot happen without your assistance, and I do ask that you provide the new Rector and his or her team with the same understanding and support which I have enjoyed from you.

In conclusion
I am grateful.

To the many hundreds of students who have passed through my office and our home, and who sat in my many lectures and engaged me in your residences – thank you for enriching my sense of life and leadership. I am grateful that Grace and I could support and mentor many of you over the years and see you graduate. I am a better leader because of you.

To the staff of the three campuses – there is no university Rector, I can assure you, who enjoyed more love and support than what you offered me since the day I arrived here. Students come and go, but you have been my foundation year after year, and I thank you for that.

To parents, friends, and followers off-campus, in South Africa and abroad – thank you for hundreds of letters, emails, phone calls, prayers and ‘packages of support’ (from biltong to books). In the most difficult times, you rallied from everywhere with a word of support, often on social media. Know this: your words kept me calm in the storm.

Thank you, everyone.

Goodbye.

Prof Jonathan Jansen
