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 Columbia Lost-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.
Overview Who are older workers and why should we be interested in them? Older age and the prevention of work injuries. Older age and the consequences of work injuries. Related plans for future research in Victoria
Who are older workers and why should we be interested in them?
Who are older workers? Human Resources and Skill Development Canada = 45 years or older Statistics Canada & European Foundation for the Improvement of Living and Working Conditions = 55 years or older
Workers’ Compensation policy around older workers in Canada Loss 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

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.
Aging biological, psychological, social and societal change Chronological age Functional age Societal age Organisational age Kooij et al, J Man Psych, 2008
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?

Questions What is the role that chronic conditions and functional declines associated with age play in the risk of work injury? Palmer et al (2008), OEM, 65, 757 -- 764

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
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?
57 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?
58 Planned future work at MonCOEH Developing a framework for occupational health and safety vulnerability (underway – funded through ISCRR) Understanding individual, workplace and system level influences on return to work in the context of the ageing Victorian labour market. The influence of types of injuries and measures of chronological and functional age (work in progress – funded through ISCRR)
