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. Specialized case management teams, new evidence-based health services, and expedited access to expert medical intervention are some of the initiatives implemented at the WSIB in recent years to improve outcomes related to high impact claims.

High impact claims refer to three specific types of claims - those involving the low back, shoulder, and fractures. These claims account for 42 per cent of all benefit payments and almost 32 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 Six Months will be available in fall 2017.


High Impact Claims as a Percentage of All Lost Time Claims

In general, the percentage of lost time claims related to low back injuries has continued to decrease since 2012. Over the same five year period, the percentage of fracture and shoulder injuries has remained fairly constant.

In 2016, the three types of high impact claims represented approximately 32 per cent of all lost time claims, of which low back claims accounted for the highest proportion at 17 per cent.


The leading characteristics for high impact claims have remained fairly consistent since 2013. The services, health care, manufacturing, and construction sectors continue to account for more than 70 per cent of all high impact claims. Similarly, male workers continue to represent about 65 per cent of all high impact injuries and those aged 50 to 54 years experience the highest percentage of these injuries.
