Infection Control Matters

Vaccine hesitancy and the role of social scientists in infection prevention with A/Professor Holly Seale

In this episode Brett Mitchell talks to Associate Professor Holly Seale about the role of social scientists, vaccine hesitancy, booster vaccines and the potential implications for the next influenza season. Holly is an infectious disease social scientist at the School of Population Health at the University of New South Wales in Australia. She has over 15 years of experience in undertaking social science research focused on improving confidence and engagement of different at-risk groups with immunisation and other prevention strategies.

Environmental decontamination reduces healthcare infections - a systematic review with Alexandra Peters

In this week's episode, Martin Kiernan talks to Alexandra Peters, who works in Prof. Didier Pittet's group at the University Hospitals of Geneva and with a WHO Collaborating Centre. We discuss a new systematic review that demonstrates that there is significant evidence that environmental decontamination reduces healthcare-associated infections and colonisations and also progress on a new Healthcare Environmentsl Hygiene (HEH) self-assessment tool, the results of which will shortly be published.
Papers that we discuss are:

Infection Prevention Team Staffing levels - Less (staff) is more (infections)?

In this week's episode, Brett Mitchell and Martin Kiernan use a recent paper published in Infection Control and Hospital Epidemiology to start a discussion about an relationship between IPC Team staffiing levels and levels of healthcare-associated infections. How are staffing levels set and is it just a number or is there more to it? The papers that we discuss are listed below.

Could a virtual Infection Prevention Service provide support in middle and low income countries? With Prof Gonzalo Bearman

In this episode, Martin Kiernan talks to Professor Gonzalo Bearman, Chair, Division of Infectious Diseases and Hospital Epidemiologist/Medical Director of VCU Healthcare and the Richard P. Wenzel Professor of Internal Medicine at the Virginia Commonwealth University Health System (full CV here) 
Following on from the increase in virtual working due to the pandemic, we discuss the potential for providing healthcare facilities in low and middle income countries with virtual support and consulting. The papers that we discuss are listed here.

Hand drying - a lot of hot air?

In this episode, Brett Mitchell and Martin Kiernan discuss methods of drying hands after hand hygiene has been performed, with a focus on hand dryers versus paper towel. Personal details about Martin's habits are disclosed as we mull this over and present some papers.

Mouth Care Matters - Oral hygiene & healthcare associated infection

In this episode we return to another ICM favourite topic, healthcare-associated pneumonia that is not device-associated. Martin Kiernan talks to Dr Mark Garvey, Director of Infection Prevention and Helen Woodall, Senior Dental Nurse, both of University Hospitals Birmingham NHS Trust about the 'Mouth Care Matters' initiative. Education of registered nurses and healthcare assistants was a key part of the strategy, which ultimately resulted in a significant reduction in infections.
Note that in England a 'Trust' is an NHS healthcare provider organisation which may be made up of more than one hospital or unit.
The paper outlining the initiative and results can be found here https://www.journalofinfection.com/article/S0163-4453(21)00275-9/fulltext

Airborne Transmission - would air filtration reduce a range of infections and why is there reluctance to recognise it? With Matt Butler, Christine Peters and Evonne Curran

In this, the first episode of 2022, Martin Kiernan talks to Dr Matt Butler, Consultant Geriatrician (Addenbrookes Hospital, Cambridge, UK), Dr Christine Peters, Consultant Microbiologist (NHS Greater Glasgow, Scotland) and Dr Evonne Curran, now an independent IPC Consultant. We start off by discussing how Matt came to design a study that looks at the effect of air filtration on a range of infections, including respiratory viruses and more 'common' pathogens like Clostridium difficile. We also discuss why it had taken so long for airborne transmission to be accepted as a mode of transmission. Books recommended by Evonne in the podcast are listed below.
