Comparing child product safety concerns with injury incidents: Does the evidence support the
response?
Presentation Aims
1. Describe methods to utilise existing injury data for product safety surveillance purposes
2. Discuss approaches to proactively prioritise areas for further investigation using injury data
3. Outline findings from comparison of product safety regulatory data and injury data for Qld children
Background
• Recent reviews of product safety regulation in Australia and legislative changes ->– Increasing requirement for safety of consumer goods– Reporting of injuries/deaths associated with products– Need for evidence-base to support system
• Reactive vs proactive surveillance• Criticisms of utility of injury data for product safety
surveillance but costs of establishing new system too high, thus need to use existing data sources
Product-focus vs Risk-focus• Product-focused surveillance considers each
product individually to assess level of risk and determine responses to a specific product
• Risk-focused surveillance prioritises hazards of concern– Specific hazards -> distinct injuries– Greater utility of injury data under hazard-based model– May be universal design/regulatory/information standards
across range of products as preventative measures
Hazard Risk InjuryMoving and rotating objects Cutting/piercing Open wounds, amputation
Drowning Drowning Drowning
Hazardous heights Falls Contusions, open wounds, fractures
Inadequate stability Falls Contusions, wounds, fractures, crush
Inadequate structural integrity Falls Contusions, wounds, fractures, crush
Flammability Fire/hot object Burn
Open flames Fire/hot object Burn
Small objects Foreign bodies Choking, internal injuries
Toxicity Poisoning Poisoning
Projectiles Struck by object Open wounds
Non-permeable enclosures Suffocation Suffocation
Gaps and openings Suffocation; Cutting/piercing Asphyxiation, strangulation, amputation

Utility of injury data for product safety regulators
Data sought Data availableFrequency National ED data, hospital data, and mortality data; two
state-based injury surveillance systemProduct-specific data Broad objects, ED text descriptions
Risk-specific data Mechanism and type of injury
Severity Admission rates, diagnosis-based injury severity, length of stay, discharge outcomes
Vulnerable groups Demographics (age, region, gender, country of birth etc)
Injury scenario Presenting problem and injury description text
Accessible, recent data Systematic compilation of data which is approx 6-12 months old is possible with ethics/health dept sign off
Exposure data Not available
Examples from Qld Child Product-Related Injury Study
• Data sources:– Product safety documents outlining investigations,
recalls, compliance checks, bans/standards etc– Emergency department injury presentation data– Hospital admission injury data
• Scope:– Children under 18 years of age– Incident/investigation occurring in 2008 or 2009– Queensland-based
• Document analysis, secondary data analysis and text mining
Product-focused surveillanceAge group Product safety Injury data (ED and hospital)
<1 year Pacifiers, prams, cots Beds, tables, couches, prams, change tables
1-3 years Squeeze toys, toy vehicles, projectile toys
Tables, beds, chairs, couches, toys
4-12 years Magnets, bunk beds Trampolines, scooters, bicycles, skateboards, balls

Risk-focused surveillance
Other important considerations
• Weighing up frequency and severity rankings (see Jesani Limbong’s poster)
• Consideration of proportion of consumer product involvement per mechanism
• Product causality (product fault vs user behaviour)• Potential for product safety intervention• Evaluation of efficacy of interventions• Exposure and inherent risk ratios
Conclusions• CAN the evidence support the response? YES, by:
– Using a risk-focused proactive surveillance approach– Compiling injury data regularly to build an information
resource – Using coded and text data to identify cases and explore
circumstances– Using severity indicators as well as frequency data to
prioritise rank order of hazards by age groups• DOES the evidence support the response for
product-related injury in children? PARTIALLY:– Age groups and some products/hazards concordant– Identification of hazards which require further
investigation
