Prioritization of leading operational indicators in occupational safety and health.

New approaches are necessary to ensure the effectiveness of an occupational safety and health management system (OSHMS), which include the development of new methods that would facilitate the measurement of the proactive operational status. This study addresses the development of a tool that contains leading operational indicators in occupational safety and health (OSH), with the main objective of prioritizing these indicators according to the consensual opinion of groups of experts. The Delphi method was applied to this manageable list to prioritize the indicators through three rounds, and consensus was obtained on which indicators are most relevant, both for each individual group of experts and for all experts.
