The Institute for Work & Health
• Independent, non-profit research institute in Toronto, Canada• Majority of funding from the Ontario WSIB ($4.7 million)• Plus approx 2.5 million / year from competitive funding
agencies• Two broad research goals
• to protect the health of workers by studying the prevention of work-related injury and illness.
• to improve the health and recovery of injured workers. • Staff of 22 scientists from a variety of disciplines• Approximately 80 FTE staff in total• Governed by a Board of Directors and a Scientific Advisory
Committee

Compensation systems in Ontario and British ColumbiaLost-time claims (LTCs)After the day if accident/illness, the worker is absent from work; or has reduction in earnings (through fewer hours at old job or
lower wages doing modified work).
No-lost-time-claims (NLTCs)Worker requires health care (arising from work injury or illness), but is not absent from work other than the day of Injury. Also includes modified work for more than seven days at regular pay and hours, even without health care.

Workers’ Compensation policy around older workers in CanadaLoss of earning benefits End at age 65 for workers who were less than 63-years-old at
the time of injury Workers who are injured when over the age of 63 are paid loss
of earnings for up to two years after the date of injury. In some provinces (e.g. BC) entitlements may be extended
past age 65
Health Care Is available to workers past age 65, regardless their age at
injury
Re-employment Employer’s obligation to re-employ injured workers ends on
the date a worker turns 65 years of age

Summary
Older workers are an increasing proportion of the labour force– More older people– More wanting to work– A greater percentage in temporary employment
relationships
In Canada, 11% of people over the age of 65 are working (up from 6% in 2000)
These trends will likely further increase as more workers “choose” not to retire

Age and work injury
General assumption that risk of work-related injury declines with age, but that when injuries do occur they are usually more serious

Summary
Compensation boards are dealing with an increasing number of claims from workers over the age of 45 years of age.
Older age is not always associated with a reduced risk of injury – relationship differs by gender, occupational exposures and injury type
The relationship between age and work injury has changed over time. Differences in injury rates are now less pronounced.
In Australia, not all age and gender groups have had reductions in injury risk between 2005-06 and 2009-10. This has changed the relationship between age and work injury.

Thinking outside of chronological age to understand issues related to the aging workforce
Functional age: what is the relationship between chronic conditions and work injury and recovery from work injury?
Societal age: are older workers treated differently by the health care or compensation system than younger workers, even with the same type of injury?
Organisational age: are older workers treated differently in the workplace than younger workers, even with the same type of injury?

Summary Limited research is currently available on how changes in
function, societal or organisational age impact on risk of work injury
Available data in Canada suggests that chronic conditions associated with older age are associated with an increased probability of both acute work injuries and repetitive movement injuries
Statistically significant risk for arthritis and back problems among both men and women.

Summary Older age is associated with more severe consequences even
after the same event
In Ontario, age differences in health care costs and time lost from work after a injury are increasing– severity of injury– health care utilisation (both number of treatments and
type of treatments)
The relationship between aspects of aging (outside of chronological age) and the consequences of work injury (wage replacement and health care costs) is not known ....

Overall Summary
What we know The Canadian labour force is aging While work after age 65 is not common, it is increasing Rates of injuries generally decline with age, although not
always. This relationship is changing. Chronic conditions, in particular arthritis and back problems,
are associated with increased risk of work injury (acute and repetitive movement) among men and women
Differences in health care expenditures across age groups may be widening
Differences in the duration of wage replacement across age groups may be widening
![Page 56: The ageing workforce and its implications for occupational health and safety prevention programs and work-injury compensation systems: A Canadian perspective.](https://reader036.fdocuments.in/reader036/viewer/2022062312/551bccf2550346b4588b5235/html5/thumbnails/56.jpg)
Overall Summary
What we need to know What specific aspects of aging impact both primary and
secondary prevention of work injuries – Are specific chronic conditions associated with more severe
injuries? greater health care utilisation, costs or time away from work? Is this morbidity or injury specific?
– Is there an interplay between measures of functional age and occupational characteristics in return to work after injury?
– Are older workers treated differently (by medical, workplace, compensation) than younger workers even after the same injury?
What happens to workers injured when 63 and older?

Planned future work at MonCOEH
The relationship between age and work injury and the consequences of work injury in Victoria using information from the Compensation Research Database (CRD)
– Estimating the size of the insured labour force in Victoria across key labour market characteristics (e.g. age, gender, occupation)
– Time trends in the relationship between age and different injury outcomes (e.g. health care spending, days off work).
– How similar are trends in workers’ compensation claims to trends in self-reported injury?
