Summary
Postpartum hemorrhage, a leading cause of maternal mortality, saw an increase in British Columbia. Atonic postpartum hemorrhage and severe cases significantly rose between 2000 and 2009.
Area of Science:
- Obstetrics and Gynecology
- Maternal Health
- Epidemiology
Background:
- Postpartum hemorrhage (PPH) is a critical factor in maternal mortality and morbidity.
- PPH incidence in Canada rose between 1991 and 2004.
- This study focuses on PPH epidemiology in British Columbia from 2000-2009.
Purpose of the Study:
- To describe the epidemiology of postpartum hemorrhage in British Columbia.
- To analyze trends and severity of PPH between 2000 and 2009.
- To identify changes in PPH subtypes and their management.
Main Methods:
- Utilized data from the British Columbia Perinatal Data Registry for deliveries between 2000-2009.
- Identified severe PPH cases through blood transfusions or surgical interventions.
- Assessed PPH rates and changes over time using rates, rate ratios, and 95% confidence intervals.
Main Results:
- Overall PPH rates increased by 27% (2000-2009), with atonic PPH rising by 33%.
- Atonic PPH with blood transfusion increased from 17.8 to 25.5 per 10,000 deliveries.
- Severe atonic PPH requiring surgical intervention rose from 1.8 to 5.6 per 10,000 deliveries, particularly from 2006-2009.
Conclusions:
- Atonic PPH and severe atonic PPH incidence escalated in British Columbia.
- The rise in atonic PPH was observed across diverse demographic and clinical factors.
- Further research is necessary to determine the underlying causes of this increase.
