Dr. Janssen is a perinatal epidemiologist with a clinical background in obstetrical nursing. She conducts clinical trials to evaluate methods of pregnancy and labour management and interventions for mothers at particularly high risk for experiencing adverse perinatal outcomes. The British Columbia Reproductive Care Program Perinatal Registry linked to Ministry of Health data is used to evaluate outcomes and cost of specific methods of delivering obstetrical care.
She is validating new standards for intrauterine growth stratified on sex and ethnicity, and has completed a large CIHR-funded multicentre trial of early labour management. She is currently studying risk factors for prolonged latent phase labour. Her leadership on a knowledge translation initiative named Optimal Birth BC is aimed at reducing variation in rates of caesarean section across B.C.’s health authorities. As part of Optimal Birth BC, she is 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.
