Infection Control Matters

The Sinkbug Survey: Antibiotics, AMR, Chemicals and Plumbing

In this episode of Infection Control Matters, Martin Kiernan speaks with Dr. Nicole Stoesser about a large-scale, multi-centre study exploring the role of hospital sink infrastructure in antimicrobial resistance and pathogen dissemination. Representing the collaborative NITCAR-led "Sinkbug Consortium" we discuss surprising findings from 29 UK hospitals—including widespread antibiotic residues in sink traps—and reflect on the implications for sink design, waste disposal practices, and infection prevention strategies

Surveillance for HCAI - What is important, feasible and useful - and what isn't..

In this episode, Brett and Martin chat with Dr. Jessica Schults and Dr. Sally Havers about a recent study published in the American Journal of Infection Control. The study used a modified Delphi process to identify key healthcare infection surveillance priorities in Queensland.
Through a two-round methodology, infection prevention experts identified 13 key infection measures for a standardized minimum dataset. This dataset aims to improve statewide HAI surveillance, enhance data consistency, and support targeted infection prevention efforts. The findings offer a model that could inform broader national and international surveillance strategies.

nv-HAP surveillance too time-consuming? Semi-automated may be easier than you think

In this episode, Phil and Martin talk to Dr Aline Wolfensberger, Senior Attending Physician, Department of Infectious Diseases and Hospital Epidemiology at University Hospital Zurich and a Senior Researcher at the Institute for Implementation Science in Health Care at the Univetsity of Zurich. We discuss a recent paper that has analysed a range of algorithms for detecting non-ventilator associated pneumonia (nvHAP) that have the potential for significantly reducing the surveillance burden. This work also demonstrated the value of an annual local hospital-wide point prevalence survey that provides data on which areas to target.

Methods of assessing effectiveness of hospital cleaning - a review and peek into the future?

In this episode Martin Talks to Silvana Gastaldi who is a infection prevention and control health referent at UK-MED (a frontline humanitarian medical NGO). We discuss her revent paper in the Journal of Hospital Infection that reviews the literature on methods of assessing how effective environmental cleaning services and procedures are, including ATP, fluorescent UV marking, visual and microbiological methods and also discuss the potential for AI to assist in the healthcare environmental decontamination arena.

Reducing CAUTI in intermittent self-catheterisation. The trial that didn't make it..

In this episode, Phil Russo talks to Brett Mitchell and Kate Browne about a study that did not make it over the line. Following a systematic review in 2021 that examined the issue of UTIs in those who self catheterise, a study to examine whether previous work demonstrating a reduction in CAUTI in indwelling catheters through the use of Chlorhexidine for meatal cleansing would be effective was designed. The team discuss the complexities of getting what was essentially a community-based study over the line and why ultimately it did not progress, much to the sadness of the team. previous relevant work is listed below.

In-room air purification to prevent respiratory infection in aged care - Does it help?

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.

Do you have enough staff in your IP Team? Calculating the staffing requirement for your program

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:
