Is there a correlation between complete blood count parameters and nutritional risk score 2002, geriatric nutritional risk index and nutric score in geriatric patients admitted to intensive care unit

Abstract

Aim: Malnutrition is a common condition especially in geriatric patients admitted to intensive care. There are various screening tools to be used in the evaluation of nutritional status in geriatric patients hospitalized in intensive care. However, a laboratory test has not been found yet for nutritional status assessment. With this study, we aimed to investigate whether there is a correlation between NLR, PLR, and complete blood count parameters at the time of admission to the intensive care unit and NRS-2002, GNRI, and mNutric Score measured in the intensive care unit. Material and Method: This retrospective study was performed in a tertiary intensive care unit of a Chest Diseases Hospital. Patients aged 65 and over were included in the study. Demographic data, length of stay in intensive care, complete blood count on the day of admission to the intensive care unit, albumin value, NLR, PLR, NRS-2002, GNRI, and mNutric Score values were recorded. Results: A total of 218 geriatric patients were analyzed. It was determined that 72.5% of the patients were at medium/high risk in terms of nutritional risk according to the GNRI classification, 76.6% were at high risk according to NRS-2002, and 84.9% were at high risk according to the mNutric score. According to the GNRI, the MPV values were statistically significantly higher (p<0.05). According to the biserial correlation analysis, there is a statistically significant correlation between GNRI and MPV in the positive direction (p<0.05). The cut-off value for MPV was determined as 7.895 in terms of nutritional risk assessment Conclusion: It was observed that the majority of geriatric patients in the intensive care unit were at high risk for malnutrition according to nutritional scores. It was determined that the MPV value of the patients in the intermediate/high-risk group for GNRI was significantly higher and there was a positive correlation between MPV and GNRI. The cut-off value for MPV was determined as 7.895 in terms of nutritional risk assessment. We think that MPV can be used practically in nutritional risk scoring in geriatric patients hospitalized in the intensive care unit.
