Early detection of severe maternal morbidity: a retrospective assessment of the role of an Early Warning Score System.

BACKGROUND: The Early Warning Scoring (EWS) surveillance system is used to identify deteriorating patients and enable appropriate staff to be called promptly. However, there is a lack of evidence that EWS surveillance systems lead to a reduction in severe morbidity. AIMS: To determine whether as EWS may have improved the detection of severe maternal morbidity or lessened the severity of illness among women with severe morbidity at a large tertiary maternity unit at Auckland City Hospital (ACH), New Zealand. METHODS: Admissions to intensive care, cardiothoracic and vascular intensive care, or an obstetric high-dependency unit (HDU) were identified from clinical and hospital administrative databases. Case reviews and transcribed observation charts were presented to a multidisciplinary review group who, through group consensus, determined whether an EWS might have hastened recognition and/or escalation and effective treatment. RESULTS: The multidisciplinary review team determined that an EWS might have reduced the seriousness of maternal morbidity in five cases (7.6%), including three admissions for obstetric sepsis to intensive care unit and two to obstetric HDU for post-partum haemorrhage. No patient had a complete set of respiratory rate, heart rate, blood pressure and temperature recordings at every time period. CONCLUSIONS: These findings have been used to support introduction of an EWS to the maternity unit at ACH.

Review of contributory factors in maternity admissions to intensive care at a New Zealand tertiary hospital.

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. STUDY DESIGN: 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. CONCLUSION: 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.

Pregnancy in blue rubber bleb syndrome: a case report.

Blue rubber bleb nevus syndrome is a disorder characterized by cutaneous and visceral venous malformations with a potential for life-threatening hemorrhage. Only 3 reports of blue rubber bleb nevus syndrome in pregnant women can be found by a Medline search. We present our experience in the management of this rare condition in pregnancy.
