Stefan Dreesen
Stefan Dreesen is a publisher and health writer at Hospital News who focuses on turning complex hospital-based research and innovation into clear, practical stories for health care professionals. His coverage centres on clinical breakthroughs, emerging applications of artificial intelligence in medicine, and the operational pressures facing hospitals, often highlighting world-first procedures and major collaborative studies. His vantage point as publisher of a long-standing health care news outlet informs a broad view of how individual advances and system-level pressures connect.
Clinical breakthroughs in Canadian hospitals
Dreesen regularly reports on first-in-kind procedures and novel therapies emerging from Canadian hospitals, emphasizing the clinical details and patient impact of these advances. His work on a world-first burn treatment with “absolutely remarkable” results at a leading Canadian hospital reflects a focus on how new techniques change outcomes at the bedside.
He has covered a Sunnybrook-led breakthrough in which scientists non-invasively opened the blood–brain barrier to deliver a small dose of immunotherapy directly to the brain of a patient with ALS, explaining how this approach enhances drug access to affected areas. In cardiac care, he reports on trials showing that continuous nerve blocks after open-heart surgery can significantly cut opioid use, highlighting reduced requirements and lower likelihood of high-dose needs during recovery.
He also profiles critical care research, such as a major international study comparing CPAP, high-flow nasal cannula, and bilevel non-invasive ventilation to standard oxygen therapy, noting that these modalities reduce the need for invasive ventilation in critically ill patients. His coverage of living heart tissue created with in-house 3D printing from patient-derived stem cells shows how reproducible tissue samples that mimic real human heart behaviour can accelerate testing of new treatments.
Alongside these technology-driven pieces, he also writes about clinical recognition and organ donation, including a feature on a coordinator honoured for advancing organ donation, which ties innovation to the people who make it work.
AI and data-driven innovation in health care
A second strand in Dreesen’s work is the use of artificial intelligence and advanced analytics to reshape diagnosis, research, and hospital operations. He covers privacy-first AI initiatives such as federated learning projects in Canadian cancer research, outlining how distributed data strategies allow centres to collaborate without compromising patient privacy. His reporting on AI-driven blood testing emphasizes the potential for automation and intelligent analysis to save billions of dollars, linking technical advances to system-wide financial impact.
He writes about how health care leaders can build robust AI risk management frameworks, positioning AI not only as a tool but as a governance challenge that must be handled carefully in clinical environments.
Dreesen also explores large-scale digital transformation, including the design of an AI-enabled hospital information system slated to go live at a major organization, showing how integrated systems can support medical decision-making and operational efficiency. Across these stories, he presents AI as part of a continuum from research to deployment, balancing enthusiasm for innovation with attention to risk, cost, and implementation.
Health system pressures and public health
Dreesen’s articles also address the pressures facing hospitals and the wider health system, connecting policy and public health themes to daily realities in care settings. He has written about growing pressures on the hospital sector, situating these challenges within public health, health care policy, and patient care and signalling the strain on institutions and professionals. In his piece on closing immunization gaps to boost health and the economy, he links vaccination coverage with both clinical outcomes and broader economic effects, underscoring how public health decisions reverberate through the system. By covering these topics in the same outlet that reports on cutting-edge clinical science and digital innovation, he consistently frames breakthroughs against the backdrop of resource constraints and policy trade-offs.
Human factors and behaviour in care and work
Beyond technology and policy, Dreesen writes about the human and behavioural dimensions of health care and the workplace. His feature on procrastination and the brain explores how everyday behaviour can affect performance and well-being, bringing cognitive and psychological themes into a health context. Stories that honour coordinators advancing organ donation and clinicians reducing opioid exposure after surgery highlight individual initiative and patient-centred care as essential complements to technological progress.
This human-focused thread, combined with his clinical and systems reporting, makes his body of work a blend of science, operations, and the personal factors that shape health outcomes.
As publisher and regular contributor to Hospital News, Dreesen works within a publication that has covered developments and issues affecting health care professionals, administrators, patients, visitors, and students for decades, positioning his writing within a broad national view of hospital care. His articles are typically structured around clear summaries of key study findings or innovations, followed by practical implications for practice and policy, as seen in his concise “HN Summary” treatment of nerve block trials after cardiac surgery. Taken together, his work is distinguished by a consistent focus on clinical and technological innovation in hospitals, framed against system pressures and human factors, and written for readers who need accessible, evidence-based accounts of change in health care.

Alanna Smith
Alanna Smith is a national health reporter whose work links health policy and politics to real access to care, with a constant focus on health equity, infectious disease and the toxic drug crisis. She reports for The Globe and Mail on infectious diseases, hospitals and long-term care, mental health, drug policy and the pressures on health systems in Western Canada. Her stories connect big-picture decisions to patients, families, front-line workers and volunteers, showing how funding, privatization and federal standards shape public care. She has covered trauma care inequities, proposed public‑private models in Alberta, drug toxicity and overdose policy, respiratory virus surges, measles elimination, gene‑editing advances and gender‑affirming health care laws. Her work combines narrative reporting, data, legal and policy analysis, and has been recognized by national journalism and press freedom organizations.
Allan Levine
Allan Levine is a historian and author whose journalism uses the past to explain present-day issues. He writes for the Winnipeg Free Press, including the Now & Then column, which examines current events through history. His subjects include public health, disease, medical treatment, health systems, politics, social conflict, strikes, wars, antisemitism and Canadian public life. His polio reporting traces Manitoba epidemics, hospital pressures, treatment, mortality and the arrival of vaccines through archival data and medical history. He also writes about the Winnipeg General Strike and Jewish communities, including discrimination, rights and security. His work draws on books about Canadian political leaders, Jewish history and the wartime economy, including The Dollar A Year Men. He writes long-form, analytical pieces that combine dates, statistics, policy decisions and narrative storytelling to connect people and institutions with broader historical change.
