The Australasian Maternity Outcomes Surveillance System (AMOSS) studies rare and serious conditions in pregnancy, childbirth and the post-natal phase. By translating its findings into reliable evidence-based practice, AMOSS aims to improve the safety and quality of maternity care in Australia and New Zealand.

The AMOSS project

The AMOSS project is based at the Faculty of Health, University of Technology in Sydney, Australia. In New Zealand, AMOSS is run under the umbrella of the PMMRC.

Data are collected through the network of PMMRC local coordinators (one in each DHB). For each condition under investigation, data collection establishes the number of women experiencing the disorder, how the disorder is managed and what the outcomes have been. Data collection is not identifiable and is limited to information recorded in clinical records. Only agents of the PMMRC have access to these data.

Conditions under investigation 2017:
Completed data collection 2010–16
  • Antenatal pulmonary embolism
  • Women with rheumatic heart disease
  • Women with breast cancer during pregnancy
  • Massive blood transfusion at delivery
  • Placenta accreta/increta/percreta
  • Peripartum hysterectomy
  • Eclampsia
  • Influenza A H1N1 admission to intensive care units
  • Morbid obesity (BMI>50) - collection of numbers only
