Infection Control Matters

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. 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. We welcome comment, suggestions and ideas. Please consider subscribing for updates and to find collections of topic specific podcasts at

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:

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.

Thursday Mar 09, 2023

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".

Tuesday Feb 28, 2023

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.
Here are the papers we refer to in the podcast:
DAVIS, M., JETHANI, L., ROBBINS, E. & KANER, M. 2023. Is It Really the Foley? A Systematic Review of Bladder Management and Infection Risk. Top Spinal Cord Inj Rehabil, 29, 94-107.
