In this episode Brett and Phil chat about a few of the posters presented at the Australasian College for Infection Prevention and Control 2024 Conference held in Melbourne in November 2024. Poster topics include hand hygiene, surveillance, and a pilot RCT on chlorhexidine impregnated dressings.

You can access poster abstracts below and a pdf of the posters here

In this episode recorded at the 2024 Australasian College of Infection Prevention and Control (ACIPC) Conference in Melbourne, Brett and Phil talk to Dr Sarah Browning (ID Physician at Hunter New England) and two Junior Medical Officers (JMOs) Sam and Lochlan who worked on IPC-related projects whilst on placement.

In this episode, Brett, Phil and Martin reflect on the year. We chat about favourite podcasts, papers and conferences in our usual informal manner (well probably even more informal than normal). Papers we mention are listed below.

In this episode of ICMs we talk to the authors of a world first multi-centre double blind cross-over randomised control trial, which explored the effect of in-room air purification on acute respiratory tract infections. The rationale and pragmatics of undertaking such a trial are explored, as well as interpretation of the findings.

The lead researcher, Bismi Thottiyil Sultanmuhammed Abdul, a PhD student at the University of Newcastle is joined by some of her supervisors Professors Jenny Sim and Brett Mitchell to explain this study.

In this episode, Martin talks to Dr Rebecca Crapanzano-Sigafoos (formerly Bartles) who is Executive Director, Center for Research, Practoce and Innovation at the Association for Professionals in Infection Control and Epidemiology (APIC). We talk about about her work on staffing levels for IPC Teams, beginning with her early work looking at workload and then the recent review and paper on data obtained from the beta version of the APIC Staffing Calculator. It turns out that the vast majority of 390+ participating organisations are understaffed.. What might help however was the finding that hospitals that were better staffed had significantly lower infection rates according to accepted published data. Papers we discuss are found below:

In this episode, Martin talks to Cansu Cimen, a researcher at University Hospitals Groningen in the Netherlands, about a recent paper that documents an outbreak and in particular the critical role of next-generation sequencing (NGS) in tracking and controlling the transmission of MDROs via contaminated duodenoscopes.

Focusing on an outbreak linked to ESBL-producing Citrobacter freundii and Klebsiella pneumoniae after endoscopic retrograde cholangiopancreatography (ERCP), standard culture methods failed to detect contamination. After many negative cultures using established methods, destructive dismantling of the implicated scope revealed contamination on hard-to-clean components, highlighting NGS as an effective tool for identifying pathogen transmission pathways.

In this episode recorded live at the IPS Conference in Birmingham UK in September 2024, Martin talks to Claire Fitzsimons, Senior Infection Prevention and Control Practitioner at the Northern Ireland Ambulance Service Health and Social Care Trust. We discuss a poster that she presented at the conference that looked as ways of reducing glove use in the ambulance service through a range of improvement methodologies.

A copy of the poster can be found here

In this episode, recorded at the 2024 Infection Prevention Society Conference in Birmingham (UK) Brett and Martin talk to Conor McGinn, Assistant Professor in the Department of Mechanical and Manufacturing Engineering at Trinity College Dublin and CEO of Akara AI, a robotics company spin-off from Trinity. We talk about a presentation that Conor gave, demonstrating how infrared sensors analysed by AI can provode feedback on techniques in the operating room and how they could improve cleaning standards in hospitals.
