Glycemic Ratio Is a Superior Predictor of Mortality Compared With Stress Hyperglycemia Ratio in Critically Ill Patients
Authors' conclusion
Glycemic ratio was superior to SHR as a predictor of mortality. This study demonstrates that a mean ICU BG level representing 80% to 100% of the patient's EPBG was associated with the lowest mortality rate in a heterogeneous cohort of critically ill patients.
Study context
- Population
- Patients treated in a university-affiliated medical-surgical intensive care unit (ICU) from 2019 to 2023 with >4 ICU blood glucose (BG) measurements and HbA1c measured at admission
- Participants
- 4,148 patients
- Exposure
- Glycemic ratio vs stress hyperglycemia ratio as predictors of mortality
- Outcome
- Mortality (prognostic ability of SHR and GR)
Methodological detailssingle-centre, university-affiliated medical-surgical ICU, prespecified glycemic ratio (GR) and stress hyperglycemia ratio (SHR) bands
- Single-centre
- University-affiliated medical-surgical ICU
- Prespecified GR and SHR bands
Main finding
As reported in the abstract
Mortality in reference band 0.8 to <1.0
P = 0.0087
Observational data: associations, not effects.
Further findings
Mortality in stratum ≥1.4
P = 0.0376
Observed:expected mortality ratio (OEMR) vs reference band
- GR <0.8 and GR >1.0 had higher OEMR vs reference band
- P < 0.0001 for each
- OEMR for SHR <0.8 and >1.0 vs reference band not significantly different
