Objectives In this study, we aimed to determine the correlation between procalcitonin (PCT) levels and clinical outcomes including in-hospital mortality, ICU length of stay, and hospital length of stay in patients hospitalized with COVID-19. Methods Clinical, laboratory, and demographic data of 223 patients who met inclusion criteria were analyzed. PCT measurements of 0.25 ng/mL and 0.50 ng/mL were used to stratify patients into two mutually exclusive groups Results Patients with PCT above 0.25 ng/mL on admission had significantly elevated APACHE II scores (9 vs. 8; P = 0.042) and CRP levels (111 μg/mL vs. 79 μg/mL; P = 0.007). A multivariable binary logistic regression model demonstrated no relationship between PCT and mortality (OR = 1.00; 95% Cl: 0.97 to 1.02; P = 0.713). Kaplan-Meier analysis revealed no statistical evidence of a difference between PCT groups and hospital length of stay (P = 0.144 for 0.25 ng/mL, P = 0.368 for 0.50 ng/mL) or intensive care unit length of stay (P = 0.986 for 0.25 ng/mL, P = 0.771 for 0.50 ng/mL). Conclusions Elevated PCT levels were associated with severity of illness but did not correlate with in-hospital mortality, hospital length of stay, or ICU length of stay.
