Effect of first application laboratory values on the prognosis of COVID-19 patients hospitalized in the intensive care unit

OBJECTIVE: The aim of the study was to investigate the effect of blood values at first admission to the hospital on predicting mortality in COVID-19 patients hospitalized in the intensive care unit (ICU). PATIENTS AND METHODS: The blood parameters of 284 intensive care patients, who were diagnosed with COVID-19 via the Real-Time Polymerase Chain Reaction (RT-PCR) for SARS-CoV-2 RNA test, at first admission to the hospital, were evaluated. The contribution of these parameters to predicting mortality was analyzed. RESULTS: No significant relationship was found between complete blood count and mortality. However, it was determined that the ferritin, ALT, D-dimer, and urea levels significantly affected the mortality rates in intensive care patients. CONCLUSIONS: The ferritin, ALT, D-dimer, and urea levels of patients who were admitted to the ICU due to COVID-19, at first admission to the hospital, were significant in predicting mortality. Therefore, it is recommended that these parameters will be evaluated at the first application.
