The efficiency of HALP score, neutrophil-lymphocyte ratio, and platelet-lymphocyte ratio in predicting mortality in intensive care patients

Abstract

Objective: The HALP Score, which is a combination of hemoglobin, albumin, lymphocytes, and platelets, is a new index that shows nutritional status and systemic inflammation, provides information about patient prognosis. In this study, we aimed to investigate the relationship of HALP score, platelet-lymphocyte ratio (PLR), neutrophil-lymphocyte ratio (NLR) and with poor prognosis in intensive care patients. Material and Method: Our study was designed retrospectively on patients admitted from the emergency department (ED) to the intensive care unit (ICU). HALP scores, PLR and NLR values were calculated from the hemoglobin, albumin, lymphocyte, platelet and neutrophil values taken from the patients within 24 hours. One-week and three-month mortality were determined as poor outcomes. The relationship between results and poor outcomes was investigated. Results: A total of 250 patients were included in the study. The median age of the patients was 72.5%, and 43.6% (n=109) were female. When the variables between survivors and non-survivors were compared, NLR was found to be significantly higher in non-survivors. In addition, there was a significant difference between the two groups in terms of both one-week and three-month mortality regarding age, albumin, lymphocyte, and thrombocyte values. When we analyzed the diagnostic performances of HALP Score, NLR, and PLR for one-week and three-month mortality, only NLR showed significant diagnostic performance. The optimal cut-off point for NLR for both one-week and three-month mortality was 8.22 (for one-week mortality: AUC=0.598, p=0.007; for three-month mortality: AUC=0.592, p=0.011). Conclusion: It was observed that the HALP score was not an effective parameter in predicting prognosis in intensive care patients. It is thought that NLR has a significant relationship with one-week and three-month mortality and can be used as an effective parameter in the prediction of prognosis in intensive care patients.
