Comorbidity score for the prediction of severe maternal morbidity in a high-risk population

Abstract

Comorbidity scores predict severe maternal morbidity (SMM) and are used to identify and develop interventions for patients at risk of SMM. Most comorbidity scores are developed from claims databases and are representative of low-risk populations (risk of SMM of 1.2% and < 5% prevalence of obesity, diabetes, substance use and chronic hypertension [CHTN]). We sought to assess the predictive ability of a previously developed comorbidity score for SMM in a high-risk population.
