How to set up a regional specialist referral service for Placenta Accreta Spectrum (PAS) disorders?

Abstract

There has been an approximately fivefold increase in the incidence of placenta accreta spectrum (PAS) disorders during the last 30 years, believed to be secondary to increasing Caesarean section rates. PAS disorder is associated with significantly increased maternal morbidity and mortality worldwide. Antenatal diagnosis by foetal medicine teams that have a special expertise to diagnose PAS disorder by the use of ultrasound scan, and a dedicated, highly specialised multidisciplinary team (MDT) comprising surgeons who are skilled in complex pelvic surgery and obstetric anaesthetists who have an expertise in high-risk obstetric anaesthesia, supported by haematology, operating theatre, interventional radiology, midwifery, neonatology, high-dependency and intensive care teams have been recommended to improve maternal and perinatal outcomes. Setting up a specialist MDT regional referral service, PAS involves collaboration with all stakeholders, ensuring appropriate funding, developing MDT care pathways, continuously auditing patient outcomes and disseminating knowledge through research, innovation, education and publications.
