Canadian Perinatal Surveillance System

The Canadian Perinatal Surveillance System is a national surveillance initiative that monitors maternal, fetal, newborn, and perinatal health outcomes across Canada, producing evidence used by agencies such as Public Health Agency of Canada, Health Canada, Statistics Canada and provincial ministries like Ontario Ministry of Health and British Columbia Ministry of Health. It collaborates with academic partners at institutions including the University of Toronto, McGill University, University of British Columbia, and the University of Alberta and informs clinical guideline developers such as the Society of Obstetricians and Gynaecologists of Canada and professional associations like the Canadian Paediatric Society.

Overview

The system integrates routine administrative data from Statistics Canada and clinical registry data contributed by provincial perinatal programs such as Perinatal Services BC and Better Outcomes Registry & Network (BORN) Ontario with research cohorts from universities including McMaster University and Université de Montréal. Outputs support policy makers at bodies like the Canadian Institutes of Health Research and international partners such as the World Health Organization and the Pan American Health Organization. Surveillance topics include maternal morbidity studied alongside work from the Maternal Morbidity Working Group, neonatal outcomes referenced by Canadian Neonatal Network, and perinatal mental health linked to research centers such as the Women’s Health Research Institute.

History and Development

Origins trace to federal-provincial efforts in the late 20th century when agencies such as Health Canada and Statistics Canada responded to calls from clinician groups including the Canadian Paediatric Society and the Society of Obstetricians and Gynaecologists of Canada for standardized indicators. Significant milestones involve collaborations with academic centers like University of Calgary and national reviews led by panels connected to the Canadian Institutes of Health Research and the Public Health Agency of Canada. Expansion of computerized registries followed models seen at Perinatal Data Collection Systems in other countries and drew on methodological advances from investigators at Harvard University and Johns Hopkins University through international exchanges.

Governance and Organization

Governance features interjurisdictional committees comprising representatives from federal agencies such as Public Health Agency of Canada, provincial entities including Alberta Health Services and Saskatchewan Health Authority, and academic partners from Dalhousie University and Queen’s University. Advisory input comes from clinical societies like the Canadian Medical Association, the Canadian Obstetrical and Gynaecological Sciences Foundation, and consumer groups allied with March of Dimes Canada and Indigenous health organizations including Assembly of First Nations. Data-sharing agreements mirror frameworks used by Canadian Institute for Health Information and ethical oversight engages research ethics boards at institutions such as Simon Fraser University.

Data Collection and Methodology

Data sources combine vital statistics from Statistics Canada, perinatal registries such as BORN Ontario, hospital discharge abstracts used by Canadian Institute for Health Information, and sentinel surveillance from neonatal networks like the Canadian Neonatal Network. Methodological approaches apply case definitions consistent with international standards from the World Health Organization and analytic methods developed in collaboration with biostatistics groups at McGill University and University of Toronto. Linkage techniques use probabilistic matching similar to methods used by Scotland’s Information Services Division and privacy frameworks reflect principles from the Tri-Council Policy Statement and provincial privacy commissioners such as Office of the Privacy Commissioner of Canada.

Key Programs and Surveillance Indicators

Key programs monitor indicators including maternal mortality evaluated against frameworks endorsed by World Health Organization, severe maternal morbidity paralleling metrics from the Centers for Disease Control and Prevention, preterm birth rates comparable to data reported by Euro-Peristat, neonatal mortality tracked using standards from the United Nations Children’s Fund, and congenital anomalies surveillance aligned with registries like the European Surveillance of Congenital Anomalies. Programs involve collaborations with perinatal quality initiatives such as Perinatal Services BC, neonatal research consortia like the Canadian Neonatal Network, and maternal health research units at The Hospital for Sick Children.

Findings and Public Health Impact

Reports have documented trends including changes in preterm birth and cesarean section rates, influencing clinical recommendations by bodies like the Society of Obstetricians and Gynaecologists of Canada and policy shifts in provincial ministries such as Manitoba Health and Nova Scotia Health Authority. Surveillance findings informed public health responses during emergencies referenced by Public Health Agency of Canada guidance and supported research published by investigators affiliated with University of Calgary and Université Laval. Data have underpinned interventions promoted by organizations such as the Canadian Perinatal Surveillance Network and contributed to international comparisons with countries represented in forums like the Organisation for Economic Co-operation and Development.

Challenges and Future Directions

Persistent challenges include data harmonization across jurisdictions such as Quebec and Nunavut, timeliness of linked datasets relative to standards set by European Perinatal Health Report contributors, and ensuring Indigenous data sovereignty aligned with mandates from Indigenous Services Canada and First Nations Health Authority. Future directions emphasize enhanced linkage with provincial registries, incorporation of patient-reported outcomes from initiatives at Canadian Primary Care Sentinel Surveillance Network, application of machine learning approaches developed at Vector Institute, and strengthened partnerships with international agencies like the World Health Organization and the Pan American Health Organization.
