Infection Control Matters

In this episode, Brett and Martin talked to Dr Nico Tom Mutters about the papers he selected in the always popular 'Year in Infection Control' session at ESCMID Global 2026. Nico is Director of the Institute for Hygiene and Public Health at Bonn University Hospital and also Chair of EUCIC (European Committee on Infection Control). It is always fascinating to see which papers are selected in these sessions and we discussed a few papers that he selected from the preceding 12 months, a list of which follow.

In this episode, recorded live from Interclean in Amsterdam, Brett and Martin highlight the contibution of Clean Hospitals to healthcare hygiene and reflect on the contrast between healthcare cleaning and the wider cleaning industry. While the scale, innovation, and investment in cleaning technology are impressive, much of it is not designed with healthcare realities in mind. We discuss why cleaning in hospitals is fundamentally different — shaped by interruptions, human behaviour, complex environments, and higher-risk pathogens.

In this episode, Martin and Brett talk about what is a high risk and what is a high touch surface. Are they the same? The discussion is based on the following paper: Zheng et al (2025). “High-touch” surfaces are not always “high-risk” surfaces in ICU environment.

In this podcast, Phil and Brett speak with Dr Lyn-Li Lim from VICNISS (Victorian Healthcare Associated Infection Surveillance System)in Australia. Dr Lim and colleagues recently explored the infection prevention and control resourcing levels in 113 facilities, including FTE per 100 beds. This podcast explores the differences in resourcing for different categories of hospitals. A link to the publication is here. https://www.sciencedirect.com/science/article/pii/S019665532500570X

In this episode, Martin talks to Dr Diane Ashiru-Oredope and colleagues at the UKHSA (UK Health Security Agency) about the 2025 ESPAUR report, focusing on what the latest data mean for clinicians, infection prevention teams, and health system leaders. We explore what the latest data reveal about antimicrobial resistance and prescribing trends in England, including changes in resistance patterns among major bacterial pathogens and what this means for patient safety and clinical outcomes. We discuss what’s improving, where challenges remain, and how infection prevention and antimicrobial stewardship teams can use national surveillance data to drive meaningful local action.

In this episode, Martin talks to Dr Jon Otter, Director of Infection Prevention and Control at Guy's and St Thomas' Hospital in London, UK. We examine two complementary pieces of work that provide further insight into Candidozyma auris transmission in acute hospitals. The first demonstrates, for the first time in the UK, that ward-level wastewater reliably mirrors patient colonisation and can reveal genetically related outbreak strains using culture and PCR. The second, a case–control study, identifies clinical and environmental risk factors that shape colonisation, highlighting the significance of shared patient equipment. The paper can be found here: Davidson HC, Griffin AE, Symes L, Laing KG, Witney AA, Gould K, et al.

In this episode, Martin spoke to the authors of two compelling posters showcased at the 2025 Infection Prevention Society Conference in Brighton, each discussing practical, data-driven approaches to reducing avoidable harm. Download the posters and have a listen to two authors with a passion for their projects. First, Catherine Lemsalu, a Dental Nurse from the IPC Team at University Hospital Plymouth discusses her quality-improvement work on an acute stroke ward, demonstrating how structured mouth-care assessment, targeted staff education, and consistent daily oral care contributed to reductions in non-ventilated hospital-acquired pneumonia and Clostridioides difficile infections. Her poster highlights how simple, early interventions—done well—can strengthen antimicrobial stewardship, improve patient outcomes, and build ward-level capability through mouth-care champions. We then explored the development of a national surveillance framework and digital tool for vascular access device–related bloodstream infections (VAD-BSI) with Sue Rowlands from The Royal Wolverhampton NHS Trust. Their multidisciplinary initiative has created a standardised, user-friendly approach to classifying VAD-BSI, identifying risk factors, and generating automated visual outputs that support local reporting, audit, and education. Early pilot data show strong usability, enhanced insight into bloodstream infection epidemiology, and meaningful impact on line-care practice.

In this episode, Martin Kiernan hosts a panel discussion at the 2026 Infection Prevention Society Conference in Brighton, United Kingdom. The Panel comprised: Dr Stephane Bouchoucha, Associate Professor in Nursing and Associate Head of School (International) in the School of Nursing and Midwifery at Deakin University in Melbourne, New South Wales Australia. Stephane is the current President of the Australasian College of Infection Prevention and Control Dr Mark Garvey, Consultant Clinical Scientist in Microbiology and Deputy Director of Infection Prevention and Control for the Infection Prevention and Control Service at University Hospitals Birmingham NHS Foundation Trust (UHB) Kerry Holden, Lead Nurse and Deputy Director of Infection Prevention and Control at Gloucestershire Hospitals NHS Foundation Trust in the UK. Kerry is the current IPS Vice-President. Dr Maura Smiddy, Director of the MSc in Infection Prevention and Control at University College Cork in Ireland and Chair of the IPS Research and Development Group. Lorraine Williams, Deputy Director of Infection Prevention & Control and Lead Nurse for IPC. Lorraine is a former IPS Vice-President. Topics we discuss include: Why are infection rates not falling? What can be done to reduce infections in long-term care that require readmission to hospital If each panel member were given £1,000,000 for an implementation, what would they do? If each panel member had to stop doing something that the infection prevention team currently does, what would that be?

In this episode Martin talks to Squadron Leader Tez Cooling and Flight Lieutenant Emma Foley about their work in the Royal Air Force (RAF) retrieval service for patients with known and suspected High Consequence Infectious Disease who are transferred to specialist units in the UK. The team discuss how the Air Transportable Isolator (ATI) is used in order to safely carry out repatriations in a timely manner and the training that is required to operate suct a specialist service.

In this episode, Brett, Phil and Martin discuss a recent paper from Freya Bull and colleagues, who undertook a modelling exercise to determine what factors determine the colonisation process for long and short-term urinary catheters. It turns out that different factors are in play here and that strategies for CAUTI prevention miht be different for each. You can read the paper here: Bull F, Tavaddod S, Bommer N, Perry M, Brackley CA, Allen RJ.

A discussion on the lates papers in Surgical Site infection prevention

In this episode recorded in an Irish Bar in Nelson (NZ), Brett and Martin dive headfirst into the swirling world of toilet aerosols, airborne pathogens, and potential mitigations.We begin with a older study by Scott, Bloomfield, and Barlow examining the effectiveness of disinfection in real-world settings and how this depends heavily on practical application and behavioural compliance. Then we move to move to a recent contribution by Higham and colleagues, who shift the focus from surface disinfection to airborne exposure. Their paper presents a quantitative microbial risk assessment framework that models aerosolised viral particles generated by toilet flushing that demonstrates the importance of ventilation. Finally we discuss the work of Boone and colleagues, who evaluate a practical intervention—an air sanitizer spray—and its impact on reducing airborne virus concentrations following flushing events.
