Understanding Paediatric Burn Injury Trends in Ontario

Recent research published in BMJ Injury Prevention has shed new light on paediatric burn injuries in Ontario, Canada, revealing a significant 37% decline in incidence rates over the past two decades. This population-based study, covering 2003 to 2022, analyzed 79,782 cases among children aged 0-17 years, drawing from comprehensive linked health administrative databases managed by ICES (Institute for Clinical Evaluative Sciences). The findings underscore the effectiveness of longstanding prevention initiatives while highlighting emerging disparities that demand targeted action.

Paediatric burns, defined as thermal injuries to the skin and underlying tissues in children under 18, remain a leading cause of emergency department (ED) visits and hospitalizations. In Ontario, with its population exceeding 14 million, these injuries affect families across urban and rural divides. The median age of affected children was 4 years, with 55% being male, aligning with global patterns where young boys are disproportionately represented due to exploratory behaviors.

The Remarkable Decline: From 165 to 104 Incidents per 100,000

The study's core revelation is the drop in annual burn injury rates from 165 per 100,000 population in 2003 to 104 in 2022, confirmed through Quasi-Poisson regression modeling (rate ratio 0.98, 95% CI 0.98-0.98). This consistent downward trajectory spans both sexes equally, suggesting broad-reaching preventive measures have taken hold. Legislative changes, such as regulations mandating hot water heaters be set below 49°C (120°F) since the early 2000s, likely played a pivotal role in curbing scald burns, the most common type in toddlers.

Comparatively, national Canadian data from earlier decades showed higher burdens; a 10-year study ending in 2007 reported over 10,000 hospitalizations and 494 deaths nationwide, with peaks in children under 5. Ontario's progress mirrors global trends, where improved safety standards and awareness campaigns have reduced paediatric burns by up to 50% in high-income countries.

Demographic Patterns: Age, Sex, and Geography

Younger children dominate statistics, with the interquartile range spanning 1-12 years, reflecting heightened vulnerability during early mobility stages. Males' overrepresentation (55%) ties to riskier play, while females show parallel declines. Rural residents experienced steeper drops, possibly due to enhanced community education and infrastructure upgrades like safer heating systems in remote homes.

• Ages 0-4: Highest incidence, often scalds from hot liquids.
• Ages 13-17: Sharpest decline, linked to reduced flame exposures via fire safety laws.
• Urban vs. rural: Urban rates stabilized lower post-2010s.

Children of adolescent mothers (under 20 at birth) saw substantial reductions, crediting maternal support programs integrated into Ontario's public health framework.

Sociodemographic Disparities: The Refugee Immigrant Concern

Amid overall success, refugee immigrants faced a 91% rise (63 to 120 per 100,000; rate ratio 1.04, 95% CI 1.02-1.06), sourced from Immigration, Refugees and Citizenship Canada data up to 2020. This uptick may stem from overcrowded housing, unfamiliar appliances, language barriers in safety messaging, or cultural cooking practices involving open flames. Tailored interventions, such as multilingual resources and settlement-house audits, are urgently recommended.

Neighbourhood income showed no stark divides in declines, indicating equitable policy impact, though lower-income areas historically bore higher burdens from older wiring or space heaters.

Access to Specialized Care: Critical Gaps Exposed

A companion study by the same team found only 21.6% of 34,812 children meeting burn center referral criteria (e.g., >10% total body surface area [TBSA], chemical/electrical burns) received specialized treatment. Non-specialized facilities handled 78.4%, risking suboptimal outcomes like scarring or infection. Over 20 years, burn center use rose 20%, but barriers persist in transport, awareness, or triage protocols.Adherence to Burn Center Referral Criteria study

Ontario's burn centers, like those at SickKids Hospital for Sick Children in Toronto, advocate for streamlined referrals to optimize recovery and reduce long-term morbidity.

Common Mechanisms: Scalds, Contact, and Flames

Though the trends study focused on incidence, complementary Eastern Ontario data (2010-2015) pinpoint scalds (hot liquids) at 50-60%, contact burns (irons, ovens) at 30%, and flames at 10-15% in older kids. Rural flame risks contrast urban scalds, informing zoned prevention.

Proven Prevention Strategies Driving the Decline

Ontario's success stems from multifaceted efforts:

• Legislation: Hot water caps, flame-retardant sleepwear standards.
• Education: Parachute Canada's campaigns on no tablecloths, constant supervision.Parachute burns prevention
• Product Safety: Safer irons/cordless appliances, smoke detectors mandates.
• Community Programs: SickKids' holiday safety tips, immigrant-focused workshops.

🔥 These measures, sustained since the 1990s, exemplify public health triumphs.

University Research Powering Insights: U Toronto and SickKids

Lead author Dr. Eduardo Gus, a paediatric plastic surgeon at SickKids and University of Toronto faculty, spearheaded this work through the Edwin S.H. Leong Centre. Co-authors from ICES, SickKids Research Institute, and Dalla Lana School of Public Health highlight interdisciplinary academic collaboration. Such studies inform training for future clinicians and researchers, with opportunities in research positions at Canadian universities.

Policy Implications and Stakeholder Perspectives

Health Canada and Ontario Ministry of Health praise the decline but call for refugee-tailored programs. Parachute Canada emphasizes data-driven advocacy, while burn associations push referral reforms. Economically, fewer severe cases save millions in care costs, freeing resources for equity gaps.

Future Outlook: Sustaining Gains Amid New Challenges

Projections suggest continued decline barring complacency, but climate-driven wildfires pose flame risks. Digital tools like AI triage apps and VR simulations for immigrant training offer promise. Ongoing surveillance via ICES ensures adaptability, positioning Ontario as a model for paediatric injury prevention globally.
