Abstract

For several years now, the IRSST has produced and disseminated statistical indicators of compensated occupational injuries (frequency, severity, frequency-severity, costs) every five years using CSST administrative data with, on average, three years of maturity.

These indicators provide an overview of the situation three years after the compensation claim. However, some occupational injuries give rise to disbursements (expenses and compensation) and compensated days for longer than three years. Such injuries may incur significant compensation costs. The consequences are probably expensive when all the financial and human costs are taken into account.

Due to the maturity of the data used at the IRSST, the consequences of such injuries are not fully evidenced by the five-year indicators produced under the current approach. As things stand, it is impossible to know how using a longer maturity would effect these indicators.

The purpose of this study is to analyze the impact of data maturity on OHS indicator estimates produced at the IRSST by using injury prevalence data from 2006 to 2014 and changing the three-year maturity period to eight years for 2006 injuries.
