RESUMO
BACKGROUND AND AIMS: Hyperglycemia is a condition often found in hospitalized patients due to stress injury, parenteral nutrition or medications administered during hospitalization. According to previous studies, hyperglycemia could be an independent predictor of mortality. The objective of the study is to assess the risk of mortality in non-diabetic patients with hyperglycemia during hospitalization. METHODS: In this systematic review, we conducted literature reviews on several databases. Twelve studies were retrieved and critically reviewed using NOS. RESULTS: A majority of the studies reported that hospital related hyperglycemia increased the mortality rate. CONCLUSIONS: Hospital related hyperglycemia is an independent predictor factor for both in-hospital and long-term mortality.
