Infection Control Matters

In this podcast, Brett talks to Adjunct A/Professor Greg Whiteley about adenosine triphosphate (ATP). We chat about its use in healthcare as a way to evaluate environmental cleanliness.

Greg is an Adjunct Associate Professor in the Faculty of Medicine and Health at the University of Sydney, and is also an adjunct Fellow in the School of Medicine at Western Sydney University. Greg is also the Executive Chairman of Whiteley Corporation, a manufacturer of Therapeutic Goods based in the Hunter Region of New South Wales. His particular expertise is in the measurement of cleanliness, particularly based on rapid ATP testing where he is internationally renowned, published and is a regular keynote conference speaker.

In this, the first episode of 2022, Martin Kiernan talks to Dr Matt Butler, Consultant Geriatrician (Addenbrookes Hospital, Cambridge, UK), Dr Christine Peters, Consultant Microbiologist (NHS Greater Glasgow, Scotland) and Dr Evonne Curran, now an independent IPC Consultant. We start off by discussing how Matt came to design a study that looks at the effect of air filtration on a range of infections, including respiratory viruses and more 'common' pathogens like Clostridium difficile. We also discuss why it had taken so long for airborne transmission to be accepted as a mode of transmission. Books recommended by Evonne in the podcast are listed below.

In this largely unedited Christmas special podcast, Martin, Phil and Brett reflect on podcasts undertaken in 2021 and the year that was. This podcast is a little longer as we "chinwag" about a range of different topics and issues and have a laugh along the way. We hope you enjoy.

In this week’s episode, Martin Kiernan talks to Professor Jennie Wilson of the Richard Wells Research Centre at the University of West London and current Infection Prevention Society President. We discuss her recent editorial, co-written with Associate Professor Jacqui Prieto from the University of Southampton. After 25 years of contact precautions, first introduced as putative best practice, the evidence to support this intervention has not appeared and there are suggestions that harms may be being caused through poor implementation. Contact precautions add PPE and physical isolation to Standard Precautions, however does this lead to over, and inappropriate use of PPE that is not required?

In this podcast, Phil and Brett talk to Simon Witts on a wide ranging topics related to ventilation and also touch on air scrubbers (purifiers). Simon is Director of Engineering at VA Science, with extensive experience in hospital and building ventilation design. We cover topics such as air changes, what makes a good ventilation system and hotel quarantine.  We also cover practical things like where best to sit on a bus to reduce the risk of infection.

In this podcast, Phil and Brett talk to Adjunct Professor Alison McMillan on the topics of leadership and negotiation. Alison is Australia's Chief Nursing and Midwifery Officer. We hear first hand experiences related to COVID and tips for building relationships and nursing leadership.

Professor (Practice) Alison McMillan PSM was appointed as Australia's Chief Nursing and Midwifery Officer in November 2019. In June 2021 Alison was awarded a Public Service Medal for outstanding public service to driving the Government’s national health response priorities during the COVID-19 pandemic, particularly to infection prevention measures. 

In the last ACIPC conference special podcast, Brett and Phil talk to Stephanie Curtis about wearable proximity devices for nurses and doctors - and their use for contact tracing. We also talk about other potential uses. Stephanie is an epidemiologist at the National Critical Care and Trauma Response Centre. She worked on the COVID-19 response in Victoria over 2020-2021 and recently completed Australia's field epidemiology training program, the MAE, based at Alfred Health and Burnet Institute.

Stephanie's presented findings from pilot work of proximity trackers at the ACIPC conference. The paper for this study is published in Infection, Disease and Health https://www.idhjournal.com.au/article/S2468-0451(21)00098-5/fulltext 

In this third special edition from the 2021 ACIPC Conference, Brett and Martin talk to Distinguished Professor Lidia Morawska about the science of air. Lidia was named in Times magazine as one of the 100 most influential people in the world for helping highlight the airborne spread of COVID-19.  Topics includes in this podcast include the science of aerosolisation from the respiratory tract, activities or source that dictate particle size and terminology around droplet and airbourne transmission.

About Lidia:

Professor Lidia Morawska is a Distinguished Professor in the School of Earth and Atmospheric Sciences, at the Queensland University of Technology (QUT) in Brisbane. Lidia is an author of over 950 journal papers, book chapters and conference papers and has also been involved at the executive level with a number of relevant national and international professional bodies and has been acting as an advisor to the WHO.

In this second special edition from the 2021 ACIPC Conference, Brett Mitchell and Martin Kiernan talk to Drs Mary Wyer and Su-yin Hor. Mary and Su-Yin's work on Video Reflexive Ethnography (VRE - not that one) is world-reknowned with many publications. In this discussion they outline how the use of  video to examine and develop practice has helped in biopreparedness as well as its uses in other areas of infection prevention and control and nurse education.

In this special ACIPC conference episode, Brett Mitchell and Martin Kiernan talk to Dr Gillian-Ray-Barruel, from Griffith University School of Nursing and Midwifery and QEII Jubilee Hospital, Brisbane.

Gillian is presenting at the 2021 virtual ACIPC Conference on urinary catheter awareness. Gillian has an long standing interest in medical device placement, and this paper focuses on patient and staff awareness of the need for the catheter. Naturally we digress into other areas such as consent and nurse advocacy!
