Collection and usage attributes
Acute care public hospitals are defined as all public hospitals including those hospitals defined as public psychiatric hospitals in the Public Hospital Establishment National Minimum Data Set.
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:
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 on day 5), then this would be considered a second patient-episode of SAB.
Analysis by state and territory is based on location of the hospital.
Presented as number and per 10,000 patient days.
Coverage: Denominator ÷ Number of patient days for all public hospitals in the state or territory.
Any variation from the specifications by jurisdictions will be footnoted and described in the data quality statement.

Disaggregation is subject to data quality considerations. Some disaggregation may result in numbers too small for publication.
|Disaggregation data elements:|
For some states and territories there is less than 100 percent coverage of hospitals. This may impact on the reported rate. For those jurisdictions with incomplete coverage of acute care public hospitals (in the numerator), only patient days for those hospitals that contribute data are included (in the denominator). Specifically, if a hospital was not included in the SAB surveillance arrangements for part of the year, then the patient days for that part of the year are excluded. If part of the hospital was not included in the SAB surveillance arrangements (e.g. children's wards, psychiatric wards), then patient days for that part of the hospial are excluded. Patient days for 'non-acute' hospitals (such as rehabilitation and psychiatric hospitals) are included if the hospital was included in the SAB surveillance arrangements, but not otherwise.
Only episodes associated with acute public hospital care in each jurisdiction should be counted. If a case is associated with care provided in another jurisdiction (cross border flows) then it is reported (where known) by the jurisdiction where the care associated with the SAB occurred.
Patient episodes associated with care provided by private hopitals and non-hospital health care are excluded.
Almost all patient episodes of SAB will be diagnosed when the patient is an admitted patient. However, the intention is that cases are reported whether they were associated with admitted patient care or non-admitted patient care in public acute care hospitals.
Where there are significant variation, for example non-coverage of cases diagnosed less than 48 hours after admission, in the data collection arrangements it will affect the calculation of values across states and territories.
Variation in admission practices across jurisdictions will influence the denominator for this indicator impacting on comparability of rates.
Jurisdictional manuals should be referred to for full details of definitions used in infection control surveillance.
