High-impact claims by benefit payment percentage

High-impact claims are allowed lost-time claims that have big impacts on employees and businesses. We focus on return-to-work and recovery outcomes and supporting employees and businesses to lower the impacts of these claims. We have made changes to our processes to improve outcomes in these claims, including adding specialized case management teams, new evidence-based health services, and quicker access to expert medical treatment.

We have identified three types of high impact claims - low back claims, shoulder and fractures. These claims represent about 25 per cent of all benefits paid and about 22 per cent of all allowed lost-time claims.

High-impact claims average days lost

Due to the nature of high-impact claims, the average days lost within three and six months post injury or illness is usually higher for these claim types in comparison to all other lost-time claims combined.

The WSIB continues to focus on programs aimed at improving recovery and return-to-work outcomes for high-impact claims.



Data for average days lost within three months published Fall 2019 and data for six months will be available in Winter 2019.

High-impact claims as a percentage of all lost-time claims

In 2018, the three types of high-impact claims made up 22 per cent of all lost-time claims. Low back claims had the highest number of these claims at 12 per cent. Between 2017 and 2018, the percentage of fracture and shoulder claims stayed the same while the percentage of low back claims went down slightly.

In Schedule 2, the percentage of high-impact claims was at the lowest percentage it has been in the past five years.



In 2018 high-impact claims were split 50 per cent between men and women. This is different from Schedule 1, where 64 per cent of high-impact claims were men. People 50 to 54 years old had the highest number of these injuries at 17 per cent.
