Dufour, 1998 (LSST, Quebec)

β = 0.154 for productivity regressed on % of companies with prevention programs. In other words, adoption of prevention programs contributed positively to productivity growth, with the magnitude of the contribution (0.006) being two-fold greater than productivity growth observed for the period studied (0.003).

Nytro, 1998 (IC, Norway)

Saksvik, 1996 (IC, Norway)

Torp, 2000 (IC, Norway)

Effect

23% of companies perceived improvement in various aspects of OHSMS due to implementation of IC, 1 yr post-intervention (23% is median of results for 4 different aspects of the OHSMS) Increase from 8% (at 1 yr post- intervention) to 45% (at 4 yrs) of companies which have fully implemented IC. 29

30% of companies’ report increased HES awareness due to implementation of IC, 1 yr post-intervention29 Median std β = 0.11 for 9 intermediate outcomes (incl. psychosocial working environment, physical working environment) regressed on degree of IC implementation, 4 years post- intervention

Lewchuk, 1996 (Bill 70, Ontario)

Saksvik, 1996 (IC, Norway)

Torp, 2000 (IC, Norway)

Regression coefficient, β = -0.015 for LTI frequency regressed on legislation change. In other words, 18% decrease in LTI from pre- to post-intervention β = 0.09 for change in absenteeism rate regressed on IC status, 1 yr post- intervention; β = 0.05 for change in accident rate regressed on IC status Std β = - 0.076 for musculoskeletal symptoms regressed on IC status, 4 yrs post-intervention; Std β = -0.013 for sick leave regressed on IC status

27 Direction of effect is interpreted such that “+” is consistent with more implementation, better safety, and more financial benefits

28 29 n.d. = not determined. This figure derived from the study by weighting the results so that they account for the fact that only a sub-sample (n=911) from the entire sample (n=2092) responded to these questions (the non- respondents were those who hadn’t started implementing IC at all)
