Pregnancy hypertension remains one of the leading causes of maternal morbidity and mortality in Latin America, despite advances in rapid response protocols. In this context, the present study analyzed the relationship between timely activation of the Clave Azul protocol and maternal outcomes in women with hypertensive disorders of pregnancy, emphasizing the role of the nursing team. A retrospective analytical study was conducted in a tertiary public hospital during 2025, with a sample of 132 patients. Activation times, nursing performance, and clinical outcomes were evaluated using bivariate analysis, multivariate regression, and statistical mediation. The findings demonstrated that each ten-minute delay in activation increased the likelihood of severe maternal morbidity by 45%, while better nursing performance significantly reduced this risk and mediated 27% of the total effect of time on morbidity. Furthermore, an increase in the need for ICU admission and length of hospital stay was observed with delayed activation. The results confirm that the timely response and technical competence of nursing staff are essential protective factors for maternal safety and the effectiveness of the Blue Key protocol.
