About this trial

This research project aims to enhance the safety of childbirth by using advanced computer models to predict the risk of postpartum hemorrhage (PPH).

PPH is a significant concern for mothers during and after delivery. Current risk assessment tools are basic and do not adapt to changing conditions. This study will investigate whether a new and recently validated model for predicting PPH, combined with a provider-facing Best Practice Advisory (BPA) regarding currently recommended strategies triggered by an increased predicted risk, can improve perinatal outcomes.

This study will compare the current category based risk assessment tool with a new, enhanced prediction model which calculates risk based on 21 factors, automatically updates as new information becomes available during labor and, if elevated, provides a provider-facing Best Practice Advisory (BPA) recommending consideration of strategies that are institutionally agreed to represent high-quality practice.

Investigators hypothesize that the enhanced care approach will result in improved perinatal outcomes.

The goal of the study is to improve the wellbeing of mothers during childbirth by harnessing the power of modern technology and data analysis.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

All vaginal and cesarean deliveries occurring at Vanderbilt University Medical Center

Disqualifiers

All patients will be randomized at the time of admission to the obstetric service. Patients who are discharged prior to delivery will be excluded from subsequent analysis. Any patients with a pre-delivery planned hysterectomy (for placenta increta or percreta) will be excluded from the treatment algorithm and primary analysis.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Novel PPH Risk Prediction Model - Comparator Arm B

    Behavioral

    Patients in this group will receive the standard care risk assessment with the addition of a recently developed, novel PPH risk prediction model, which will automatically calculate a patient's numerical risk of hemorrhage based on 21 risk factors. Elevated risk of hemorrhage (\>=3% predicted risk), as predicted by the model, will be linked to clinical decision support, including a best practice advisory with recommendations presented to providers for consideration when they access the patient's electronic health record.

Trial outcomes

Primary outcomes

1

Numerical hierarchical composite score of postpartum morbidity and mortality at hospital discharge

Patients will be assigned the most severe morbidity and mortality outcome score based on a range of criteria from 1 to 7 with 1 being the least severe and 7 being the most severe outcome. 1 is Estimated blood loss \<1000 mL, 2 is Estimated blood loss \>=1000 mL, 3 is Mechanical treatment of hemorrhage (uterine tamponade device insertion, uterine compression suture), 4 is Post-delivery red blood cell transfusion, 5 is Uterine artery embolization, 6 is Hysterectomy due to bleeding, and 7 is Death. For example, a patient who experiences an estimated blood loss \>=1000mL and does not experience another more serious outcome would receive a score of 2, whereas a patient who requires a hysterectomy due to bleeding might meet several of the criteria, but would receive a score of 6, as this is the most severe criteria they experience.

Time frame
Date of randomization to Postpartum hospital discharge (usually 2-4 days)
2

Numerical hierarchical composite score of postpartum morbidity and mortality at 30 days postpartum

Patients will be assigned the most severe morbidity and mortality outcome score based on a range of criteria from 1 to 7 with 1 being the least severe and 7 being the most severe outcome. 1 is Estimated blood loss \<1000 mL, 2 is Estimated blood loss \>=1000 mL, 3 is Mechanical treatment of hemorrhage (uterine tamponade device insertion, uterine compression suture), 4 is Post-delivery red blood cell transfusion, 5 is Uterine artery embolization, 6 is Hysterectomy due to bleeding, and 7 is Death. For example, a patient who experiences an estimated blood loss \>=1000mL and does not experience another more serious outcome would receive a score of 2, whereas a patient who requires a hysterectomy due to bleeding might meet several of the criteria, but would receive a score of 6, as this is the most severe criteria they experience.
