ABSTRACT The objective of this review is to summarize evidence available in the scientific literature from the applicability of the Three Delays Model in the context of maternal mortality in terms of causal factors and interventional measures. It is an integrative literature review, carried out with no time frame, in seven databases, with the descriptors Maternal Mortality, Pregnancy Complications, Maternal Death and the keyword Three Delays Model. 15 studies were selected for analysis. The first delay stood out as a determinant of maternal deaths, with the refusal to seek obstetric care in the health institution an initiative of the woman or family members. In the second delay, geographic factors and poor road infrastructure made access to health services difficult. In the third delay, the care conditions in the health institutions implied a reduced quality of care. The applicability of the model makes it possible to demonstrate the barriers faced by women in the search for obstetric care and to visualize contexts that need interventional actions to face the problem.
