Overview

I am a perinatal epidemiologist with a clinical background in obstetrical nursing. I undertake clinical trials to evaluate methods of pregnancy and labour management and interventions for mothers at particularly high risk for experiencing adverse perinatal outcomes. I use the British Columbia Reproductive Care Program Perinatal Registry linked to Ministry of Health data to evaluate outcomes and cost of specific methods of delivering obstetrical care.

Research

Current Projects
I lead a knowledge translation initiative named Optimal Birth BC which is aimed at reducing variation in rates of caesarean section across B.C.’s health authorities. As part of Optimal Birth BC, I am conducting studies to evaluate the diagnosis and management of dystocia and adherence to clinical practice guidelines for diagnosis and management of fetal distress in labour.



I am also studying trajectories of women released from provincial prisons and developing predictive measures of recidivism based on health and social networking parameters.

SmartMom and SmartParent
SmartMom and SmartParent are Canada's first prenatal and parental education programs delivered by text messaging. Over 8000 women in BC have enrolled in SmartMom, and we have demonstrated improvements in knowledge and mental health outcomes. We are now assessing other perinatal health outcomes. SmartParent is launching in the spring of 2021 in British Columbia. SmartMom has been endorsed by the Society of Obstetricians and Gynecologists of Canada and SmartParent by the Canadian Pediatric Society
