Summary

Multiparity, induced labor, and significant blood loss are key factors associated with retained placenta. This study identifies predictors to help identify high-risk cases for better management.

Area of Science:

  • Obstetrics and Gynecology
  • Reproductive Health
  • Clinical Epidemiology

Background:

  • Retained placenta is a significant obstetric complication requiring identification of associated risk factors.
  • Understanding these factors is crucial for improving maternal outcomes and reducing postpartum hemorrhage.

Purpose of the Study:

  • To identify significant covariates associated with retained placenta using logistic regression analysis.
  • To develop a predictive model for identifying women at high risk of retained placenta.

Main Methods:

  • A case-control study was conducted at King Khalid University Hospital, Saudi Arabia.
  • Data from 114 women with retained placenta and 116 controls were analyzed using Chi-square and logistic regression.
  • Predictor variable adequacy was assessed using sensitivity, specificity, and probability histograms.

Main Results:

  • Logistic regression identified multiparity, induced labor, small placenta, and excessive blood loss as significant predictors.
  • High pregnancy number, previous uterine injury, and preterm labor were also significantly associated with retained placenta.
  • The predictive model achieved 65.5% sensitivity, 87.9% specificity, and 77% overall correct classification.

Conclusions:

  • The identified covariates can be utilized to develop a predictive procedure for retained placenta.
  • Early identification of high-risk cases can facilitate timely intervention and improve patient management.
