Abstract

Objective
To investigate the relationship between mortality and laboratory values that may change with renal function and nutrition, namely creatinine, ALP, albumin, phosphorus and calcium, in patients admitted to the intensive care unit (ICU).

Method
A total of 2549 patients older than 18 years of age, who were followed up in the ICU of our hospital between 2015-2018, had no history of malignancy or pregnancy, had a length of ICU stay longer than 24 hours, and had laboratory values available at the time of admission to ICU, were included in the study.

Results
The results of our study showed that advanced age and prolonged length of stay are associated with mortality (p<0.001). Low albumin and calcium values and high creatinine and ALP values at the time of ICU admission were a risk factor for mortality (p<0.001). Phosphorus value was not an important risk factor for mortality (p: 0.753).

Conclusion
In ICU patients, the relationship between mortality and renal function and laboratory values that may change with renal function and nutrition, namely creatinine, albumin, calcium, and ALP has been shown while no such relationship was observed between phosphorus values and mortality.
