Statewide Obstetric Support Unit

A team of midwives training

The State-wide Obstetric Support Unit is a state-wide integrated service, established on evidence based best practice, that provides safe and responsive, culturally sensitive, care in an environment that nurtures, develops and supports the maternal and newborn workforce and community of Western Australia.

The State-wide Obstetric Support Unit's (SOSU) primary role is to:

  • provide support to clinicians delivering obstetric and maternity services throughout the state to enable them to provide the highest quality service possible
  • liaise and work with metropolitan and country health services to promote the use of evidence-based guidelines and principles of clinical governance
  • promote educational programs and emergency drills aimed at improving safety and quality of care
  • provide a single reference point for advice
  • advise on workforce development and support (including recruitment and retention issues) if requested
  • assist with practice and service issues resolution as required.
Maternity services viewer

The Maternity Services Viewer (external site) was developed in collaboration with the WA Country Health Service (WACHS) and the Epidemiology department at Department of Health (DoH) following feedback from our maternity service providers across the State in relation to appropriate discharge decision making and coordination of discharge both into the metropolitan area and back to rural communities.

  • There appeared to be a knowledge deficit especially regarding resourcing of rural and remote health services mismatched with the immediate antenatal/postnatal requirements for that mother and baby
  • The web-based map of WA’s regions is supported by a database of all available maternity service providers within each region
  • If there isn’t an available maternity service in that town/community, the map will direct you to the nearest hospital with a maternity service and the distance to that town
  • Included in the data base is information on hospitals with maternity services,all other non-maternity hospitals, child health services, aboriginal medical services, GP’s,nursing posts, Patient Assisted Transport Services (PATS) contact details, etc
