Erratum to: P47 A review of Massive Obstetric Haemorrhage (MOH) in the East of Ireland and its association with Maternal Obesity

Introduction: Massive obstetric haemorrhage (MOH), blood loss of >2000 ml, is a life-threatening emergency in the postpartum. The aim of this review is to address the incidence of maternal obesity, a modifiable risk factor contributing to MOH. Methods: This 6-year retrospective review involved the interrogation of the annual clinical reports of the tertiary maternal centres in the East of Ireland between the years 2009-2014. We assessed patient risk factors for developing MOH in the antenatal period with a focus on maternal obesity (Body Mass Index (BMI) ≥30 Kg/m2). Associations between categorical variables were tested using Pearson’s chisquare test. Results: The incidence of MOH was 2.21/1,000 livebirths during the 6-year period. Of those women 20.5% of cases had BMIs recorded and 34.72% of those with recorded BMI were obese. Within the obese cohort, patients suffered an average blood loss of 2820 ml in the first 24 hours postpartum, with 88% requiring a blood transfusion. There was a significant association between maternal obesity and developing MOH: (X2 (1) = 32.63, p-value < 0.001). Discussion: Maternal obesity is a preventable risk factor that contributes to MOH.
