Episodes of Staphylococcus aureus (including MRSA) bacteraemia (SAB) in acute care hospitals.
from 1 July 2009 to 30 June 2017
National and state
The dataset includes counts of cases of SAB for each public hospital covered by SAB surveillance arrangements--for some states and territories, there is less than 100% coverage of public hospitals.
Private hospitals are also invited to provide data on the same basis, but are not required to do so. In some reports, data are presented for public hospitals only.
A patient-episode of SAB is defined as a positive blood culture for Staphylococcus aureus. For surveillance purposes, only the first isolate per patient is counted, unless at least 14 days has passed without a positive blood culture, after which an additional episode is recorded.
A Staphylococcus aureus bacteraemia will be considered to be healthcare-associated if: the first positive blood culture is collected more than 48 hours after hospital admission or less than 48 hours after discharge, OR, if the first positive blood culture is collected 48 hours or less after admission and one or more of the following key clinical criteria was met for the patient-episode of SAB:
Exclusions: Cases where a known previous positive test has been obtained within the last 14 days are excluded. For example: If a patient has SAB in which 4 sets of blood cultures are positive over the initial 3 days of the patient's admission only one episode of SAB is recorded. If the same patient had a further set of positive blood cultures on day 6 of the same admission, these would not be counted again, but would be considered part of the initial patient-episode.
Note: If the same patient had a further positive blood culture 20 days after admission (i.e. greater than 14 days after their last positive blood culture on day 5), then this would be considered a second patient-episode of SAB.
