Background: Placenta previa with and without accreta spectrum are among the most serious obstetric conditions that needs a multidisciplinary team-work to achieve best maternal outcome. We reviewed our experience over 21 years at an academic tertiary hospital before and after establishment of placenta previa team
Objective: To study the experience of a single academic center managing patients with placenta previa and placenta accreta spectrum over two decades.
Design: Retrospective chart review
Patients and Methods: This study included all cases with a confirmed diagnosis of placenta previa and/or placenta accreta spectrum that were managed at King Abdulaziz University Hospital from 2001 to 2021. Paper and electronic chart reviews and a search of the birth registry book were performed for all cases.
Main Outcome Measures: Maternal morbidity and mortality due to abnormal placentation
Sample Size: 521 patients
Results: The establishment of a placenta previa team led to an increased prevalence of placenta previa, from 4 to 13.32 in 1000 deliveries, without increased maternal morbidity or mortality. Furthermore, it enhanced patient experience and resulted in satisfactory maternal outcomes.
Conclusion: Management of placenta previa and placenta accreta spectrum by a well-coordinated team was cost-effective and markedly reduced maternal morbidity and morbidity. The involvement of this team also improved patient experience, especially in cases in which high-risk interventions were required.
Limitations: Retrospective, single-center study; lack of statistical analysis; lack of a validated tool to differentiate treatment strategies
Key words: Placenta previa, placenta acrreta spectrum, prevalence, management, and maternal morbidity and mortality
