Work accidents, injuries, and illnesses are serious problems in organizations. Rates show that, despite efforts to contain these events, accidents still happen in industries, with all the implied costs for companies. ISO 45001:2018 appears on the international scene with the main goal of preventing occupational risks and those related to health within organizations, betting on continuous improvement through the standardization of an Occupational Health and Safety Management System (OSHMS). These systems are linked to results that generate positive effects when introduced in an organization, impacting both safety and productivity. This systematic review aimed to define the indicators and results related to the implementation of OSHMS through OHSAS 18001 and ISO 45001, seeking to point out the indicators related to OSHMS, categorize such indicators, and compare which OSHMS operates better. This is a systematic literature review that uses the PRISMA protocol (Gul, M., 2018), thus defining a flow with four phases for the search of the selected studies from their identification, selection, and eligibility to inclusion. In this search, inclusion and exclusion criteria were applied to 344 articles, leaving 28 studies that made up the present review. Because it is a relatively new standard, there were few articles reviewed that evaluated the indicators from ISO 45001. From the review, it was possible to see that the indicators to monitor the performance of the OSHMS must be aligned with the company's practices, and it was also seen that the results from the implementation of an OSHMS will be linked to how much the company is involved with the system. This work is essential to understand how management systems in health and safety at work should be monitored through metrics that are often already established by corporations.
