Since Staphylococcus aureus is the most common healthcare associated pathogen in most New Zealand hospitals, its rate of isolation and the number of patients with healthcare associated Staphylococcus aureus bacteraemia (HA-SAB) per 1000 inpatient days is a good outcome measure to monitor the impact of improvements in hand hygiene practice. This data should be collected by the DHB hand hygiene coordinator.
The surveillance definition that is used is drawn from that used by the Ministry of Health benchmarking project.
A new SAB implementation guide has been developed for district health boards to use to so that they can report on HA-SAB consistently, contributing to accurate national data and reliable information for quality improvement activities. This guide aims to support and standardise existing surveillance activities. It does not replace or inform clinical assessment of infections for patient management.
The Health Quality & Safety Commission publishes HA-SAB rates quarterly as part of the quality and safety marker reports. These reports run one quarter behind so April to June data will be published in September.
