Final OHS outcomes include changes in injury/illness statistics, employee quality of life, product quality, productivity, property damage,

Comparisons in Outcome studies
• Α comparison of outcome measures was required. • These comparisons could be made within or across workplaces and could be either: i) Between the presence and absence of an OHSMS intervention, or ii) Between OHSMS interventions of different intensities.
• Implementation and effectiveness studies without a comparison of outcome measures.
Facilitator and barrier studies
• A quantitative or qualitative study of facilitators or barriers to either 1. OHSMS implementation, or 2. Optimal outcomes following OHSMS implementation, • Which may have involved: i. The OHSMS itself, ii. The workplace, or iii. The environment external to the workplace. • Studies examining facilitators/barriers of optimal outcomes following OHSMS implementation required a specification of the level of OHSMS implementation.
• Facilitator/Barrier studies reflecting solely one expert’s opinion.
• Facilitators/barrier studies of optimal outcomes following OHSMS implementation without a specification of the level of OHSMS implementation.
