319. Maternal ICU admissions at the McGill University Health Centre and impact of advanced maternal age on outcomes: Retrospective chart review

Abstract

Introduction Severe maternal morbidity (SMM) necessitating intensive care unit (ICU) admission is rising. Advanced maternal age (⩾35 years, AMA) is associated with SMM, but its impact on ICU outcomes is not clear. Objectives We aimed to describe characteristics of pregnant and postpartum women admitted to the ICU at our institution, and to evaluate the impact of AMA on length of stay, need for invasive intervention, number of SMM indicators, and death. Methods We conducted a retrospective chart review of ICU admissions during, or within 42 days, of pregnancy, from January 1, 2006 to December 31, 2016. Impact of AMA on outcomes will be assessed with linear and log-linear regression. Results 205 women were admitted to the ICU during pregnancy or postpartum. We report descriptive analysis on a subset of patients (n = 97). Mean age was 32.5 ± 6 years; 39 (40.1%) had AMA. Most admissions (70.1%) occurred during postpartum period. High prevalence of hypertensive disorders of pregnancy (19.6%) and gestational diabetes (13.4%) was noted. One third delivered prematurely ( Discussion The majority of maternal ICU admissions are in the postpartum period in women with at least one maternal or fetal complication. Further analyses will explore outcomes according to maternal age.
