Infection Control Matters

In this episode recorded at the 2023 SHEA Spring Meeting in Seattle, Martin talks to Associate Professor Alex Sundermann about his work on sequencing all isolates from local healthcare settings and the discoveries that this enables. Healthcare infections due to previous admissions, endoscopes, even pseudo-outbreaks are all laid bare by this approach. Some recent papers from the group are listed below:

1. Sundermann AJ, et al. Two artificial tears outbreak-associated cases of XDR Pseudomonas aeruginosa detected through whole genome sequencing-based surveillance. medRxiv. 2023.

In this second discussion of an abstract presented at the SHEA Spring meeting 2023 in Seattle, Martin talks to MPH candidate Olivia Hess about her work on staff opinions of automated hand hygiene monitoring. Olivia works as a member of Dr Gonzalo Bearman's group at VCU Health (Virginia Commonwealth University) in Richmond, Virginia. We discuss staff attitudes to the technology and it's utility, which are almost universally negative.

Some recent papers on automated hand hygiene monitoring:

In this episode recorded at the 2023 SHEA Spring Meeting in Seattle, Martin talks to abstract presenter Dr Lamia Alam about the work of a Johns' Hopkins group on a systematic review of human factors relating to cleaning in the Operating Room. We discuss the abstract presented at the meeting and also previous work in human factors and environmental service workers from this group that are particular favourites of Martin's (detailed below).

This is the 100th episode of Infection Control Matters and includes a special announcement. A big thanks to our 110+ guests so far. In this podcast, Martin, Brett and Phil talk about what we've not covered, some stats and what is to come next.

In this episode, Martin Kiernan talks to Dr Valeria Fabre, Associate Professor of Medicine at Johns Hopkins University School of Medicine and  Associate Medical Director of the Antimicrobial Stewardship Program and an Associate Hospital Epidemiologist at the Johns Hopkins Hospital. We discuss the recent SHEA position paper on practical aspects of diagnostic stewardship and the use of the diagnostic pathway (ie, ordering, collecting, processing, reporting, and interpreting results of a diagnostic test).

Paper discussed:

In this episode Brett and Martin talk to Mairéad Skally and Prof Fidelma Fitzpatrick about their efforts to minimise Clostridioides difficile infections in the Beaumont Hospital in Dublin, Ireland. Mairéad is a Surveillance Scientist and Fidelma is a Consultant Microbiologist and also Head of Department of Clinical Microbiology at the Royal College of Surgeons (Ireland). We discuss 10 years of surveillance in the Beaumont and analysis of a rich pool of data that has helped them achieve a status quo.

In this week's episode, Martin talks to Professor Jean-Yves Maillard from the Cardiff School of Pharmacy in Wales. We discuss detention, removal and prevention of biofilms in wet and dry environments. A range of papers on this topic from his group are listed below.

In this week's episode, Brett and Martin talk to Dr Mark Garvey, Consultant Clinical Scientist at University Hospitals Birmingham in the UK. We discuss a new paper from the UHB team which looks at the practical aspects of contamination within the splash radius of a clinical hand hygiene sink in a critical care area. The range of high risk equipment within the zone is quite interesting! Papers mentioned are as below.

We talk about the knowledge attitudes and practice of nurses regarding oral hygiene of dependent inpatients in this podcast with Dr Isabel Oliveira. Understanding these is an important element of improving oral care and potentially reducing hospital acquired pneumonia (HAP) more broadly.  Isbael is a rehabilitation nurse with a particular focus and interest in dysphagia and oral care, including the prevention of HAP. She works at the  Centre for Health Studies and Research of the University of Coimbra (CEISUC) in Portugal. 

The paper referred to in this podcast is "Knowledge, attitudes and practices of nurses regarding oral hygiene of dependent inpatients".

In this episode, Brett talks to Associate Professor Matthew Davis about his clinical experience and recent systematic review, exploring the topic of whether indwelling vs intermittent catheterisation increases the risk of UTI. Matt is an Associate Professor of Physical Medicine & Rehabilitation at McGovern Medical School in Houston and has a strong clinician background in caring for people with Spinal Cord Injury.
