Abstract

Abstract: Objective: To compare the performance of the Collaborative Integrated Pregnancy High‐Dependency Estimate of Risk (CIPHER) model in predicting maternal death and near‐miss morbidity (Severe Maternal Outcome [SMO]) with the Sequential Organ Failure Assessment (SOFA), the Acute Physiology and Chronic Health Evaluation (APACHE) II, and the Simplified Acute Physiology Score (SAPS) III scores. Methods: A retrospective and a prospective study was conducted at two centers in Brazil. For each score, area under curve (AUC) was used and score calibration was assessed using the Hosmer‐Lemeshow statistic (H‐L) test and the standardized mortality ratio (SMR). Results: A cohort of 590 women was analyzed. A SMO was observed in 216 (36.6%) women. Of these, 13 (2.2%) were maternal deaths and 203 (34.4%) met one or more maternal near‐miss criteria. The CIPHER model did not show significant diagnostic ability (AUC 0.52) and consequently its calibration was poor (H‐L P < 0.05). The SAPS III had the best performance (AUC 0.77, H‐L P > 0.05 and SMR 0.85). Conclusion: The performance of the CIPHER model was lower compared to the other scores. Since the CIPHER model is not ready for clinical use, the SAPS III score should be considered for the prediction of SMO. Synopsis: The contents of this page will be used as part of issue TOC only. It will not be published as part of main article.The performance of the CIPHER model was poor, and the SAPS III score should be considered for the prediction of severe maternal outcome in intensive care units.
