A single target range of blood glucose management in the ICU setting seems to be arbitrary and further studies are required

With great interest, we followed the recent publication [1] regarding glucose management. The observational study evaluates patients in a medical-surgical intensive care unit (ICU) and reports on associations between time in targeted blood glucose range (TIR) and ICU mortality. The authors defined a TIR of 70–140 mg/dl (local hospital policy). The observed association with mortality was limited to non-diabetic patients and this is highly relevant. The presence of diabetes seems to reduce a protective effect of intensive blood glucose management in non-diabetics
