Abstract
Aim: The aim of this study is to determine the prognostic value of blood albumin (BA) in an unselected population of inpatients. Materials & methods: We performed prospective analysis of the medical documentation of 7279 patients hospitalized between July 2014 and September 2017. Results: Individuals with BA ≥3.35 mg/dl had significantly lower risk of in-hospital death (odds ratio [OR]: 0.22; 95% CI: 0.19-0.27; p < 0.001) and 14-day readmission (OR: 0.64; 95% CI: 0.55-0.77; p < 0.0001). BA concentration was the strongest favorable factor predicting inpatient survival in a Cox hazard regression model (OR: 0.43; 95% CI: 0.36-0.50; p < 0.001), did not correlate with body mass index and actual-to-ideal bodyweight ratio and was strongly affected by numerous non-nutrient factors. Conclusion: BA concentration showed similar or better predictive and diagnostic power in relation to all-cause in-hospital mortality and 14-day readmission among inpatients than selected multifactorial scores.
