How should a health system respond when things go wrong?

Pregnancy care in Canada is designed around what usually happens. But it is the rare, serious complication - the near-miss, the system fracture - that reveals whether care is truly working.

Earlier this month, over 50 clinicians, researchers, advocates, and health leaders came together in Hamilton for the CanOSS-Ontario Design Meeting - a milestone in the development of a provincial learning system for serious pregnancy complications.

At the heart of that conversation was CanOSS - the Canadian Obstetric Survey System. CanOSS is not a research project or a data repository. It is a national quality improvement initiative built to answer the question too often left unasked: why?

Why this patient, in this setting, under these circumstances? Why did the system fail to prevent harm - and what must change to prevent it in future?

The discussions were rigorous and honest - about design, about ethics, and about how to return learning to systems in ways that improve care. The outcome? More than a plan. Momentum.

As severe complications rise - and as inequities persist - this work could not be more urgent. CanOSS offers a path forward: a mechanism to help health systems reflect, respond, and reform.

This is not just a public health priority. It is a duty of care.

A core outcome set for vasa previa research.

A recent study from the Obstetrics Research and Outcomes Study (OROS) group, published in JAMA Network Open, introduces the first international core outcome set and reporting checklist for vasa previa - a rare but serious pregnancy complication.

Led by first author Tiffany Yeretsian and senior author Rohan D’Souza, the study draws on input from 115 individuals with lived experience and 89 pregnancy care providers across 27 countries. It addresses long-standing inconsistencies in how outcomes are selected and reported, which have made it difficult to build clear, evidence-based clinical guidance.

By establishing a shared framework for future studies, this work will improve the reliability of research and ensure that outcomes important to patients and families shape clinical progress.

Rohan D’Souza has been recognised with a Mid-Career Research Award at the Department of Health Research Methods, Evidence, and Impact’s 2025 Research Day.

His work continues to ask precise, necessary questions about maternal health - how evidence is shaped, whose experiences are centred, and what must shift to build systems that are more responsive, inclusive, and grounded in reality. This recognition speaks not to output, but to impact: on policy, on practice, and on the possibilities research can unlock.

On Tuesday, April 29, 2025, the Department of Health Research Methods, Evidence, and Impact (HEI) hosted its 22nd annual Research Day event at the Ron Joyce Centre. Recognized as the department’s flagship event, Research Day provides a unique opportunity for faculty, staff, learners, and alumni to...

This morning in Vienna, Rohan D’Souza was named co-recipient of the Award for Outstanding Contributions to the Field of Pregnancy and Heart Disease - an international recognition of work that is reshaping how cardiovascular conditions in pregnancy are understood, treated, and prioritised.

D’Souza leads FLOURISH, a research programme based at McMaster University that brings clinical rigour and systemic ambition to maternal health. His work has redefined standards of care and exposed critical gaps in how health systems respond to risk in pregnancy - especially for those facing cardiovascular complications.

He also leads CaNCaM-Preg, a Canada-wide research network recently awarded $5 million to reduce maternal mortality and morbidity through collaborative, data-driven change.

This award does not simply mark a milestone. It affirms a direction - toward research that begins with lived experience, resists complacency, and insists on measurable, lasting impact.

Rohan D’Souza, associate professor in the departments of Obstetrics & Gynaecology and Health Research Methods, Evidence, and Impact, has been named co-recipient – alongside Katherine Arendt – of the CPP2025 Award for Outstanding Contributions to the Field of Pregnancy and Heart Disease. He wil...

FLOURISH at CPP 2025: Advancing Research in Maternal Cardiovascular Health

Rohan D’Souza and Rizwana Ashraf will represent the FLOURISH Lab at the 9th International Congress on Cardiac Problems in Pregnancy, taking place in Vienna from 24–27 April.

Through a series of presentations, chaired sessions, and guided posters, their work will address key questions in maternal cardiovascular care - from anticoagulation protocols and outcome standardisation to emerging evidence on risk and recovery.

FLOURISH’s contribution reflects its ongoing commitment to rigorous, practice-oriented research that strengthens care for individuals with heart conditions during and after pregnancy.
