Infection prevention and control programs are vital to ensuring the health and wellbeing of healthcare consumers and staff. Infection control professionals who lead these programs are uniquely positioned with the knowledge, skills and attributes to direct effective infection control practices and policies within their healthcare setting. As with many specialisations, these individuals may choose to undertake a credentialling process, where their expertise and competence are evaluated and formally recognised by a professional body.

Article Synopsis
  • The study aimed to investigate how nurses select and use personal protective equipment (PPE), especially masks and eye protection, to prevent non-percutaneous body fluid exposure (NP BFE), guided by the Health Belief Model (HBM).
  • Results indicated that the emergency department (ED) had the highest reported incidents of NP BFE, while PPE use was alarmingly low, with 0% for face shields/masks and only 15% for goggles.
  • Despite nurses acknowledging the importance of risk assessment for NP BFE, the study highlighted a significant lack of compliance with PPE usage, particularly in the ED, contrasting with a more positive safety culture in the ICU.

Background: The successful adoption and application of infection prevention and control (IPC) principles in all healthcare settings is dependent on the degree to which healthcare workers (HCWs) are aware of the requirements, have access to program resources and information, and engage with the IPC program. This study investigates the impact of redesigning the Infection Control Department (ICD) intranet site based on user feedback followed by a targeted marketing campaign to improve website usability, awareness, and access.

Methods: In this systematic study, we used a survey plus two focus group interviews to elicit user requirements for the content and look of the ICD intranet page and identify the best communication platforms to use for the marketing campaign to launch the redesigned intranet page.

Background: Healthcare-associated infections are serious and significant complications present across healthcare services, including residential aged care facilities. Although ensuring high quality personal and clinical care delivered to older people residing in these facilities is a high national priority, there is a paucity of evidence published about outbreaks, governance and education programs held for healthcare workers within Australian residential aged care facilities. The aim of this study is to examine the scope of practice of Infection Prevention and Control professionals within Australian residential aged care facilities and the types of infection prevention and control education and training delivered.

Objective: To examine the global burden, associated point sources, and successful prevention and control measures for documented outbreaks of Burkholderia cepacia healthcare-associated infections (HAIs).

Design: Integrative review.

Methods: A review of all outbreaks of Burkholderia cepacia HAIs published in the peer-reviewed literature between January 1970 and October 2019 was conducted to identify the global burden, associated point sources, and successful prevention and control measures using the Guidelines for Outbreak Reports and Intervention Studies of Nosocomial Infections (ORION).

Article Synopsis
  • Individuals in residential and aged care facilities are at increased risk for healthcare-associated infections due to factors like age, immunity issues, and existing health conditions, as highlighted by a recent Australian Royal Commission.
  • A study of 158 facilities found that while most had documented infection prevention and control (IPC) programs, only about a quarter had dedicated IPC committees, and many lacked qualified IPC professionals.
  • To enhance the quality of care and reduce HAIs, there is a need for better organization and structured strategies in infection control in these facilities.

Introduction: Central to all efforts to control and prevent healthcare associated infections (HAIs) is the inherent need to measure the burden of infection and disease, classically referred to as surveillance. Australia does not have a national HAI surveillance system making it very difficult to systematically assess and report on the burden of hospital-acquired HAIs. This systematic review reports the incidence burden of HAIs in Australian hospitals as reported in the peer-reviewed literature from 2010 to 2016.

Background: We report an outbreak of Burkholderia cenocepacia bacteremia and infection in 11 patients predominately in intensive care units caused by contaminated ultrasound gel used in central line insertion and sterile procedures within 4 hospitals across Australia.

Methods: Burkholderia cenocepacia was first identified in the blood culture of a patient from the intensive care unit at the Gold Coast University Hospital on March 26, 2017, with 3 subsequent cases identified by April 7, 2017. The outbreak response team commenced investigative measures.

Background: Effective clinical governance is necessary to support improvements in infection control. Historically, the focus has been on ensuring that infection control practice and policy is based on evidence, and that there is use of surveillance and auditing for self-regulation and performance feedback. There has been less exploration of how contextual and organizational factors mediate an infection preventionists (IP's) ability to engage with evidence-based practice and enact good clinical governance.

Background: Despite evidence from overseas that certification and credentialing of infection control professionals (ICPs) is important to patient outcomes, there are no standardized requirements for the education and preparation of ICPs in Australia. A credentialing process (now managed by the Australasian College of Infection Prevention and Control) has been in existence since 2000; however, no evaluation has occurred.

Methods: A cross-sectional study design was used to identify the perceived barriers to credentialing and the characteristics of credentialed ICPs.

Article Synopsis
  • A study analyzed healthcare-associated (HCA) gram-negative bloodstream infections (BSI) over an 11-year period to see if they peak in summer like other infections.
  • Results showed that nonhospitalized patients experienced a rise in these infections during summer months, while climate-controlled hospitalized patients did not.
  • The main source of infection was intravascular devices, and the study suggests at-risk patients should be cautious about high temperatures and understand behaviors that could increase infection risk.

Background: The results of the Study on the Efficacy of Nosocomial Infection Control (SENIC) project demonstrated that hospitals with active infection control programs had lower rates of nosocomial infection than those without such programs. A key component of these programs was the inclusion of a systematic method for monitoring nosocomial infection and reporting these infections to clinicians.

Objectives: To identify the perspectives of surgeons in Queensland, Australia, regarding infection rate data in terms of its accuracy and usefulness as well as their perceptions regarding acceptable infection rates for surgical procedures classified as "clean" or "contaminated.
