Obstetric Comorbidity Index

Determines the risk of severity of maternal morbidity.


The obstetric comorbidity index can prospectively identify women at risk of severe maternal morbidity in a clinical setting. A particular strength of the obstetric comorbidity index is its ability to integrate multiple compounding comorbidities and highlight the cumulative risk that is associated with the patients’ conditions. Routine clinical use of the obstetric comorbidity index has the potential to identify at-risk women whose condition warrants increased surveillance and targeted care to prevent adverse maternal outcomes. It summarizes the burden of maternal comorbidities into a single number and holds promise as a maternal risk-assessment tool.
