High Impact Claims by Benefit Payment Percentage

High impact claims are allowed lost time claims that have been shown to have significant impacts on workers and employers. The WSIB is focused on return-to-work and recovery outcomes and supporting workers and employers to reduce the impacts of these claims. The WSIB has implemented many initiatives to improve outcomes in these claims, including specialized case management teams, new evidence-based health services, and expedited access to expert medical intervention.

We have identified three types of high impact claims - those involving the low back, shoulder and fractures. These claim types represent about 28 per cent of all benefits payments and about 25 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 claims 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 Six Months will be available in fall 2017.


High Impact Claims as a Percentage of All Lost Time Claims

In 2016, the three types of high impact claims made up 25 per cent of all lost time claims, of which low back claims accounted for the highest proportion at 15 per cent.

The percentage of high impact claims as a total of all lost time claims for Schedule 2 has decreased in 2016 compared with 2015 and is at its lowest level for the past five years.


In 2016, the percentage of high impact claims made by male and female workers was split evenly at 50 per cent each. This distribution differs from Schedule 1, where 65 per cent of claims for high impact injuries are experienced by male workers. Those in the 50 to 54 year old age group account for the highest proportion of these injuries at 18 per cent.
