title: Review of contributory factors in maternity admissions to intensive care at a New Zealand tertiary hospital.
abstract: OBJECTIVE
  The purpose of this study was to identify factors that contributed to severe maternal morbidity, defined by admission of pregnant women and women in the postpartum period to the intensive care unit (ICU) from 2010-2011 at Auckland City Hospital (ACH), a tertiary hospital that delivers 7500 women/year, and to determine potentially avoidable morbidity with the use of local multidisciplinary review.
  
  
  METHODS
  All admissions of pregnant women and women in the postpartum period (to 6 weeks) to the ICU at ACH from 2010-2011 were identified from hospital databases. Case notes were summarized and discussed by a multidisciplinary team. The presence of contributory factors and potentially avoidable morbidity were determined by consensus with a tool that was developed by the New Zealand Perinatal and Maternal Mortality Review Committee for the review of maternal and perinatal deaths. Specific recommendations for clinical management were identified by the multidisciplinary group.
  
  
  RESULTS
  Nine pregnant women and 33 women in the postpartum period were admitted to the ICU from 2010-2011. Contributory factors were identified in 30 cases (71%); 20 cases (48%) were considered to be potentially avoidable; personnel factors were the most commonly identified avoidable causes. Specific recommendations that resulted from the study included the need for the development of guidelines for puerperal sepsis, improved planning for women at known risk of postpartum hemorrhage, enhanced supervision of junior staff, and enhanced communication through multidisciplinary meetings.
  
  
  CONCLUSIONS
  Forty-eight percent of severe maternal morbidity, which was defined as admission to the ICU at ACH from 2010-2011, was considered to be potentially avoidable by a local multidisciplinary review team; priorities were identified for improvement of local maternity services.
