ABSTRACT

Introduction: Noninvasive mechanical ventilation is an intervention that can lower mortality if applied to the right patients at the right time; the HACOR score has been identified as a useful tool to pinpoint patients that will benefit of such intervention. Objective: In our study, we assessed the diagnostic performance of the HACOR scale to predict failure of noninvasive mechanical ventilation and to assess mortality according to the success or failure of noninvasive mechanical ventilation. Material and methods: We designed a retrospective study in patients 18 years and older in two intensive care units, analyzing a period of five years (2011-2016). Patients requiring urgent intubation, those with orders of no intubation or with incomplete medical records were excluded. Results: Populations were analyzed according to the success or failure of noninvasive mechanical ventilation; mortality was recorded. We obtained 75 patients, of which 53 (70.6%) had a successful noninvasive mechanical ventilation and 22 (29.3%) failed with such intervention. We found that HACOR score at the first hour of the placement of noninvasive mechanical ventilation and a cutoff point of four has a sensitivity of 70% and a specificity of 70%, AUC = 0.77 (IC 95% 0.63-0.9). A total of 14 (18.6%) patients died; they belonged exclusively to the group that failed NIV. Conclusion: The HACOR score has a similar performance to other associated studies; we also related NIV failure to a higher mortality rate.
