Intensive Care Admissions in Pregnancy: Analysis of a Level of Support Scoring System

Objectives Development of a validated triaging system that can be used by obstetric providers to identify obstetric patients at risk of developing severe morbidity during an admission is urgently required. Maternal Critical Care Working Group (MCCWG) recommended a “level of care” strategy that based patient acuity needs on number of individual organ systems requiring support. The objective of this study was to apply the MCCWG level of support for critical care (MCCWG LOC) scoring to pregnant women admitted to an intensive care unit (ICU) to predict maternal outcomes and to compare it to the Acute Physiology and Chronic Health Evaluation (APACHE) II scoring system. Methods In this retrospective study, we applied the MCCWG LOC scoring to pregnant women admitted to an ICU at the Detroit Medical Center, between January 2006 and December 2010. The MCCWG LOC was scored on admission to the ICU, and patients were subsequently divided into two groups (Group 1, patients requiring Level 1 and 2 support and Group 2, patients requiring level 3a and 3b support) and their outcome variables were compared. The MCCWG LOC scores were also compared to APACHE II scoring, an ICU scoring system, to test if an alignment of the two systems existed, and if they were able to predict outcomes such as death, hospital and intensive care stay. Results Sixty-nine pregnant women (0.25 % of deliveries) required admission to the ICU and 3 maternal deaths were reported. Sixty-four (92.7 %) patients had pre-existing medical problems. Fifty-eight (84 %) of admissions were secondary to a medical diagnosis. Mean APACHE II score ( p
