Introduction:The Internal Regulation Committee (IRC) is one of the management strategies created by the National Health Care Policy of the Ministry of Health in 2013. It aims to organize the access to consultations, diagnostic and therapeutic services and to hospital beds. It is necessary to know the epidemiological profile to adjust its processes to guarantee the flow in the healthcare system. As the standards for implementation were only established in 2018, several services implemented the ICR without guidelines, and there is a need to evaluate the degree of implementation. Objective: To evaluate the level of NIR implantation in two units of a public tertiary hospital complex. Methodology:Exploratory, descriptive and longitudinal study, carried out in two tertiary public hospitalization units implanted in the first half of 2016 (Emergency Unit) and the first half of 2017 (Campus Unit). Results:Due to the nature of their vocation (elective or emergency), a distinct epidemiological profile was observed, although it was possible to construct an integrated SWOT process and analysis for decision--making and planning purposes. According to the principles proposed by the Manual, both presented recommended initiatives to a greater or lesser degree. However, on the other hand, the units interviewed reinforce the need for more investment to improve the process. Conclusion: It is necessary to establish a policy for the implementation of NIRs with objective checklists that can be set and allow the temporal monitoring of their development.
