Discussion

Observational study links serum selenium levels and supplementation to lower ICU mortality in patients.

Adequate selenium repletion is linked to significantly lower ICU mortality among critically ill patients.
About 27.8% of ICU patients had selenium levels below 70 µg/L, correlated with higher severity scores.
Observational study evaluated 144 ICU patients, measuring serum selenium and analyzing clinical outcomes.
Lower selenium levels indicate greater illness severity and impact clinical outcomes, suggesting the need for supplementation.

Tan et al. (2025) studied this question.
