Evaluating the Obstetric Comorbidity Index for predicting severe maternal morbidity in postpartum hemorrhage after cesarean delivery

Obstetric Comorbidity Index for Prediction of Perioperative Severe Maternal Morbidity in Patients Undergoing Cesarean Delivery With Postpartum Hemorrhage

Observational Mahidol University · NCT06431204

This study is testing if a special scoring system can help doctors predict serious health problems after cesarean delivery due to heavy bleeding in new mothers.

What this trial studies

This observational study aims to assess the effectiveness of the Obstetric Comorbidity Index (OBCMI) in predicting severe maternal morbidity associated with postpartum hemorrhage in patients who have undergone cesarean delivery. The OBCMI, developed in 2013, has shown superior predictive capabilities compared to general comorbidity measures in obstetric populations. The study will analyze the correlation between the OBCMI and maternal morbidity, focusing on the prevalence of comorbidities during the perioperative period in a Thai context, which has not been previously explored. By enhancing risk assessment tailored to obstetric patients, the study seeks to improve maternal outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are women who have undergone cesarean delivery and are diagnosed with postpartum hemorrhage.

Not a fit: Patients who have had a cesarean delivery at less than 24 weeks of gestation or those with insufficient medical records will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better risk assessment and management strategies for women experiencing postpartum hemorrhage, ultimately improving maternal health outcomes.

How similar studies have performed: Previous studies have validated the Obstetric Comorbidity Index in various countries, demonstrating its predictive accuracy for maternal morbidities, although this specific application in Thailand is novel.
