Comments
Guide for use:
A Staphylococcus aureus bacteraemia (SAB) will be considered to be a healthcare associated event if:
EITHER
- the patient’s first SAB blood culture was collected more than 48 hours after hospital admission or less than 48 hours after discharge
OR
- the patient’s first SAB blood culture was collected less than or equal to 48 hours after hospital admission and one or more of the following key clinical criteria was met for the patient-episode of SAB.
- SAB is a complication of the presence of an indwelling medical device (e.g. intravascular line, haemodialysis vascular access, CSF shunt, urinary catheter)
- SAB occurs within 30 days of a surgical procedure where the SAB is related to the surgical site
- SAB was diagnosed within 48 hours of a related invasive instrumentation or incision
- SAB is associated with neutropenia (Neutrophils: less than 1 x 109/L) contributed to by cytotoxic therapy
The most probable healthcare associated clinical criteria should be selected.
If none of these criteria are met, then the SAB will be considered to be community-acquired for the purposes of surveillance.Origin:

Comments:
To identify whether SABs are community associated or healthcare associated, SABs should undergo a standard case review by a healthcare worker trained in Infectious Diseases/Infection Control.
