What is AMOSS?

AMOSS is a national surveillance and research system designed to study a variety of rare or serious conditions in pregnancy.

It is a dynamic system that combines a clinical and population health approach to describe the burden of these events in pregnancy, childbirth and the postnatal phase. AMOSS conditions have an estimated incidence of less than 1 in 1,000 births per year. Data are collected from maternity units with greater than 50 births per year across Australia and New Zealand.

Epidemiological investigations, including incidence and case-control studies, are conducted to provide evidence of the diagnosis, management and outcomes of rare conditions in pregnancy. The system is designed to study conditions (or interventions) based on clinical need or health priorities. Each condition is under surveillance for one year, unless otherwise specified.

In partnership with professional colleges and key stakeholders the findings from the studies will be translated into evidence-based practice. They will be used to inform policy development, clinical guidelines and educational and training resources for health providers to improve the safety and quality of maternity care in Australia and New Zealand.
