Infection Control Matters
Hosted by Brett Mitchell · EN
We are a group of professionals who work in the field of infectious disease and infection prevention and control. In this podcast series, we discuss new research and issues on the topic of infection prevention and control.
We will pick new papers of interest and will discuss them, often with an author of the paper who can give us some insights into the research that go beyond the written paper. We are unfunded and do not accept solicitations from companies or marketeers.
Authors will include nurses, doctors, academics, clinicians, administrators and leaders.
We should stress that all of our comments relate to our own opinions and that they do not necessarily reflect those institutions and employers that we relate to.

WISDOM: Using AI to Prioritise Surgical Wound Review
2w ago00:34:48Tap to summarizeArtificial intelligence has enormous potential in healthcare, but where can it genuinely improve infection prevention without replacing clinical judgement? In this episode, Phil Russo and Martin Kiernan are joined by Professor Judith Tanner (University of Nottingham) and Melissa Rochon (Guy's and St Thomas' NHS Foundation Trust) to discuss a recent paper about the WISDOM study, a randomised feasibility trial evaluating AI-assisted digital surveillance for surgical wounds after hospital discharge. Following on from a previous podcast in which patients submit wound photographs from home (https://infectioncontrolmatters.podbean.com/e/surgical-site-infection-surveillance-by-patient-generated-images/), this paper describes how AI can prioritise images that need urgent clinical review, and why this approach could transform surgical site infection surveillance while reducing unnecessary hospital visits. The guests discuss developing an AI model from almost 40,000 wound images, ensuring equitable performance across different skin tones, patient acceptance of digital follow-up, workforce redesign, and how remote monitoring could evolve into supported self-care. Rather than replacing clinicians, AI is shown to be a practical tool for helping healthcare teams focus on the patients who need them most.

Transcribe →Candidozyma auris: Disinfection and the Biofilm Problem
4w ago00:16:18Tap to summarizeCandidozyma auris has become one of the greatest environmental challenges facing infection prevention teams. Its ability to survive on surfaces, form resilient biofilms and spread within healthcare settings has raised important questions about whether our current cleaning and disinfection practices are enough. In this episode, Martin and Brett are joined by Aristotelis Papadimitriou from Athens to discuss his newly published systematic review on environmental decontamination of Candidozyma auris. They explore which disinfectants are the most effective, why biofilms change everything, the importance of fungal clades, and the significant gap between laboratory efficacy studies and the realities of cleaning busy healthcare environments.

Jun 1900:16:11Tap to summarizeIn the second ESCMID Global 2026 poster tour episode, Brett and Martin found three different and thought-provoking posters that highlight the importance of people, partnerships and communication in advancing infection prevention and control. We begin by talking to Dr Aline Wolfensberger from Zurich about a Swiss project that used human-centred design and co-production to develop practical tools that engage patients and relatives in the prevention of non-ventilator hospital-acquired pneumonia. Through a process of interviews, observations and co-design workshops, the team created innovative, low-cost solutions to promote oral care and mobilisation, demonstrating how patients and families can become active partners in prevention. https://mcdn.podbean.com/mf/download/ina7czek4ac7q83r/ESCMID_Global_2026_-_Patient_partnership_for_prevention_PPP_-_co-designed_solutions_to_engage_patients_and_relatives_in_non-ventilator_hospital-acquired_pneumonia_preventiona7pol.pdf We then examined an innovative researcher–journalist residency programme that explored the challenges of communicating science to wider audiences. The project revealed the differing cultures, expectations and pressures faced by researchers and journalists, while identifying opportunities to strengthen collaboration and improve public understanding of infectious diseases and healthcare. https://mcdn.podbean.com/mf/download/ykf54b6zejskjhwt/ESCMID_Global_2026_-_Promoting_scientific_communication-_insights_from_a_joint_researcher_journalist_residency8nweq.pdf Finally, we discussed findings from the EU-JAMRAI 2 initiative with the author. This work explored the collaboration needs of infection prevention professionals across Europe. The study highlights the value of mentorship, peer-to-peer learning and international networking in supporting professional development and sharing best practice. https://mcdn.podbean.com/mf/download/yungzdpc6fatf3zd/ESCMID_Global_2026_-_Assessment_of_peer-to-peer_collaboration_needs_across_IPC_professionals_in_Europe_an_EU-JAMRAI-2_initiative9cro2.pdf

Transcribe →ESCMID Global 2026: What Matters for Practice
May 600:27:49Tap to summarizeIn this episode, Brett and Martin reflect on the IPC components a major conference. Recorded after our visit to ESCMID Global 2026 held in Munich, Germany in April, this episode brings together key insights and conversations from across the first three days of the meeting. We reflect on emerging evidence, practical challenges, and the real-world implications for infection prevention and control, with a focus on what genuinely shifts practice rather than what simply looks good on paper. As always, the aim is to translate complex science into usable ideas for clinicians, infection preventionists, and anyone working to reduce harm from healthcare-associated infection. Sunsequent episodes will include discussions with presenters and the poster sessions will follow. In this episode we included sessions in which you might find these links interesting: Albers B, et al.

Transcribe →Why Healthcare Cleaning Is Different: Reflections from Interclean 2026
Apr 1600:13:04Tap to summarizeIn 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.

Transcribe →Automated bloodstream infection surveillance - Measuring what matters?
Apr 100:16:21Tap to summarizeHow well do we really measure bloodstream infections and could it be routinely automated? In this episode, Brett and Martin look at two papers on automated hospital-onset bacteraemia (HOB) surveillance, one a retrospective review in a single hospital in Berlin (Rüther et al) and a national UK study (Cregan, Oxford and UKHSA) exploring whether surveillance could move from local, manual processes to a fully automated national system, which was spectacularly accurate.
