Healthcare Associated Infections (HAIs)

Evidence-based practice is used to prevent and control HAIs.

In the US, an estimated 5-10% of hospitalised patients experience a HAI every year, resulting in substantial morbidity and mortality.1

  • Central line-associated bloodstream infection (CLABSI) are the most costly, accounting for approximately US$46,000 per case.2
  • International Nosocomial Infection Control Consortium (INICC) surveillance data from January 2010 through December 2015 (703 intensive care units in 50 countries) reported a CLABSI rate of 4.1 per 1000 central line days.3

The European Centre for Disease Prevention and Control reports.4

  • An average HAIs prevalence of 7.1% in European countries.
  • In at European multicentre study, the proportion of infected patients in intensive care units can be as high as 51%; most of these are HAIs.
  • Approximately 30% of patients in ICUs are affected by at least one episode of HAIs.
  • High frequency of infection is associated with the use of invasive devices, central lines, urinary catheters, and ventilators.

Lung Ultrasound - COVID-19 Response – Cross-Infection Risk

Thoracic ultrasound has rapidly gained popularity in emergency and trauma settings.

Ultrasound circumvents many of the issues that arrive with traditional radiography, such as:

  • Delay of care
  • Radiation exposure.
  • In an unstable patient, who is unfit for extended delays due to transport to the CT scanner or even bedside chest radiography, bedside ultrasound is readily available to physicians. 

Ultrasound can detect the pulmonary changes associated with pneumonia (COVID-19)5

ACEM COVID19 Guidelines: To minimise requirements for intra-hospital transport to radiology, consideration should be given to the utility of bedside point of care ultrasound (POCUS) for chest investigation where the skill set is available.6

  • Lung Ultrasound surface probe cross-infection risk
    COVID-19 Viruses can survive in the environment or on surfaces for periods of time (few hours or up to several days).
  • Transmitted via air, droplets, body fluids and contact with surfaces.
