Prenatal diagnosis of Placenta Accreta Spectrum (PAS) has been shown to improve maternal outcomes. The Placenta Accreta Index (PAI) is a standardized clinical and sonographic scoring tool that has been validated to prenatally predict PAS. However, the utility of the PAI in prediction of clinical outcomes is not known. We aim to determine if application of the PAI can be used to describe subsequent perinatal outcomes. We conducted a retrospective multicenter study with prenatally identified low-lying or placenta previa. Comparison groups were made between those with a PAI score < 4 and those with a score ≥ 4. The primary outcome is a composite of major maternal morbidity. Additionally, Image Quality (IQ) scores were calculated to understand the significance of ultrasound quality and perinatal PAS outcomes.
