Placenta Accreta Spectrum: Prevalence, Trend and Association with Sociodemographic/Obstetric Factors in a Tertiary Health Facility in Niger Delta, Nigeria

Background: Placenta accreta spectrum (PAS) describes the abnormal adherence of the placenta trophoblast to the myometrium and is associated with high foeto-maternal morbidity and mortality. This study was aimed at determining the prevalence, and trend of placenta accreta spectrum (PAS), as well as its association with sociodemographic/obstetrics factors at the Rivers State University Teaching Hospital (RSUTH). Methodology: December 2021. Descriptive and inferential statistics were derived using IBM, Statistical Product and Service Solution (SPSS) version 25.0 Armonk, NY. Results: <0.001 while other factors did not attain significance. Conclusion: Placenta accreta spectrum is not uncommon among women with pregnancies complicated by placenta praevia at the RSUTH. PAS occurred more among booked multiparous women with secondary level education and with an increasing trend. History of previous caesarean section is strongly associated with PAS.
