Investigation of admission serum creatinine as a predictor of hospital length of stay in triple-vaccinated COVID-19 inpatients

Background This study assessed the association between admission kidney function and the duration of hospitalization in triple-vaccinated coronavirus disease 2019 (COVID-19) inpatients during the omicron surge in Larissa, central Greece. Methods Regression analysis was used to estimate the effect of kidney function biomarkers on hospital length of stay (LoS) within a dataset from a cohort of 51 subjects. Results Sex- and age-adjusted admission serum creatinine was associated with hospital LoS (p=0.034). Conclusions Serum creatinine concentration on admission should be further evaluated as a possible clinical predictor of hospital LoS among triple-vaccinated COVID-19 inpatients both at the country and global level.

Automated summary

This study evaluated the association between admission kidney function and the duration of hospitalization in triple-vaccinated COVID-19 inpatients during the omicron surge in Larissa, central Greece. The results showed that admission serum creatinine was associated with hospital length of stay. Therefore, further evaluation of admission serum creatinine concentration as a potential clinical predictor of hospital length of stay among triple-vaccinated COVID-19 inpatients is warranted at both national and global levels.
