Objective: To determine if the value of the neutrophil/lymphocyte index upon arrival at the emergency room and admission to the “Intensive Care Unit” is a predictor of mortality in patients with severe COVID-19 at the Trujillo Regional Teaching Hospital in 2020. Methodology: An observational, analytical, retrospective, diagnostic test type study was carried out in patients with a diagnosis of COVID-19 admitted to the emergency room and who progressed unfavorably requiring admission to the HRDT ICU during 2020. 125 patients were included. and their neutrophil-lymphocyte index was calculated upon arrival to the emergency room and upon admission to the intensive care unit to then construct two ROC curves and identify the best cut-off point. Then, a crude and adjusted Poisson regression model was performed to evaluate the association in NLR and mortality in COVID-19 patients. Results: When constructing the ROC curve, it is evident that the NLR in the emergency through its cut-off point ≥ 6.7 with a sensitivity of 90%, specificity 87%, PPV of 98% and NPV of 57% are significantly compromised. to mortality (p=0.000) as well as the NLR at admission to the ICU with a cut-off value ≥ 8.7 with a sensitivity of 85%, specificity of 80%, PPV 97% and NPV of 43% (p=0.000). Finally, the multivariate analysis adjusted for the confounding variables showed that an NLR ≥ 6.7 at hospital admission is 1.80 times more likely to die than the group with a lower NLR. Conclusions: NLR upon arrival to the emergency room is a better predictor of mortality than upon admission to the ICU in patients with severe COVID-19 treated at the HRDT in 2020
