Project Description

Obstetric Anal Sphincter InjurieS (OASIS), also known as 3rd and 4th degree perineal tears, are a severe form of vaginal birth trauma causing anal incontinence, pelvic dysfunction and significant social and psychological morbidity. OASIS occurs in over 6500 Australian women/year with a rising incidence, adds $8800 per episode of care and is on the ACSQHC’s list of 16 high-priority Hospital Acquire Complications (HACs) for which clinical risk mitigations strategies should be prioritised.

The Vic OASIS QCIP is funded by the Medical Research Future Fund (MRFF) through the Monash Partners Advanced Health Research and Translation Centre (AHRTC) with aim of incorporating OASIS ascertainment, quality of care assessment and patient outcome measures into Victorian perinatal performance indicators. It will establish benchmarks for monitoring variation in practice to support health services, clinicians and policy makers in reducing the patient morbidity and community costs of OASIS, and act as a proof-of-concept that may be applied to other maternity care indicators.
