3. Work-related problems in General Practice
• GP treated injuries in Australia:
• 74% musculoskeletal
• 11% wounds
• 8% crush/burn
• 5% eye

4. Work-related problems in General Practice
• 3-5% of all work-related injures result in hospitalisation (Allard E Dembe et al,
(2003) 44 Am J Ind Med 331.)
• In Victoria, Australia during the period 2000 to 2010:
• 34% of injured workers see a GP on the day of the accident.
• 76% of workers compensation clients in Victoria visited a GP.
• Of those, the mean number of GP visits during the course of a claim
was 17.4 (SD 30.1).
• The workers compensation regulator spent $1.76 billion on GP services
(Collie A, unpublished data)
General Practitioners have a critical role in treatment and
rehabilitation of injured workers.
5. Australian workers’ compensation
jurisdictions
• 12 workers compensation jurisdictions
• 6 states, 2 territories, Comcare, Seacare, Dept of
Veterans’ Affairs, Dept of Defence
• Regulatory differences between
jurisdictions
• Eligibility
• Entitlements
• Societal differences between jurisdictions
• Industry mix
• Access to healthcare services (geography)
6. Aims
• To compare the proportion and nature of GP treated occupational health
problems in Australia that are claimed through workers’ compensation with
those not claimed.
• To determine the coverage of GP treated occupational health conditions by
workers’ compensation schemes between jurisdictions.
7. The Bettering the Evaluation And Care of Health
(BEACH) study
• Continuous national study of GP clinical activity, began 1998
• Random sample of 1000 GPs across Australia per annum
• Each GP records details of 100 consecutive patient encounters
• Data recorded:
• Reasons for encounter
• Problems managed
• Referrals / prescriptions
• Funding source (workers compensation, medicare, private etc..)
• Work-related

13. Nearly a quarter of work-related problems
managed by GPs are not claimed
• In Australia, 22.4% of problems managed by GPs are not claimed on
workers’ compensation.
• Consistent with prior studies:
• 57% of work-related fatalities were included in workers’ compensation
datasets (Driscoll T, et al. OEM 2003, 60; 195-201)
• 62% of surveyed Australians with work-related injury did not apply for
workers’ compensation (SafeWork Australia, 2009)
• Up to 40% of work-related injury and disease appearing on health
datasets do not arise on workers’ compensation datasets. (Driscoll T, et al. OEM
2003, 60; 195-201; Boufous A, Williamson A. Aust NZ J Pub Health 2003; 27: 352-356)
14. “Invisible” problems are less likely to be
claimed on workers compensation
• Encounters at which physically evident problems are managed are more
likely to be claimed on workers compensation.
So-called “invisible” problems are less likely to be claimed.
• Possible reasons
• Perceived negative impact of claiming
• Eligibility restrictions
• Awareness of eligibility
• Australian Work-Related Injury Survey (WRIS) 2005-06:
• Reasons for not applying for workers compensation:
• 8% - identified potential negative impact on current or future employment
• 5% - stated they were not covered by workers compensation (e.g., sole traders)
• 9% - did not think condition was eligible
15. There are jurisdictional and geographic
variations in claiming behaviour
• Significant differences between states and geographic regions.
• Queensland and the Northern Territory had the highest percent of unclaimed
encounters / Tasmania the lowest.
• Regional and remote workers less likely to claim.
• Possible reasons:
• Eligibility differences between jurisdictions
• Access to compensation systems in remote areas
• Paradox?
• “Risky” industries (e.g., forestry, agriculture, mining) are concentrated in regional /
remote areas yet GP encounters in these areas are less likely to result in a workers
compensation claim.
16. Conclusions
• GPs are an important ‘gatekeeper’ in workers compensation cases.
• Nearly a quarter of GP treated work-related problems do not result in a
workers compensation claim.
• “Invisible” problems managed by GPs are less likely to be claimed on
workers’ compensation.
• Jurisdictional and geographic differences have an impact on claiming
behaviour.

74% of all work-related injuries are musculoskeletal in nature.
