## Sugar & Survival: The Impact of Dysglycaemia
- **Overview:** Research investigation into whether abnormal blood glucose excursions during hospitalisation drive adverse clinical outcomes.
- **Key Definition:** Dysglycaemia includes hyperglycaemia (BGL >10 mmol/L), hypoglycaemia (BGL <4.0 mmol/L), and high glycaemic variability.

## Study Methodology
- **Cohort:** N = 2,847 adult inpatients at a tertiary centre (2020–2023).
- **Demographics:** Median age 64.3 years; 51% male; 38% with known diabetes.
- **Statistical Approach:** Logistic and linear regression adjusted for age, sex, comorbidities, and admission diagnosis.

## Key Research Findings
- **In-Hospital Mortality:** Dysglycaemia associated with 2.4x higher odds of death (OR 2.4, p<0.001).
- **ICU Admission:** 1.9x higher odds of unplanned ICU escalation (OR 1.9, p<0.001).
- **Infection Risk:** 1.7x higher odds of hospital-acquired infection (OR 1.7, p=0.003), including pneumonia and UTIs.
- **Length of Stay (LOS):** Dysglycaemia predicted an average increase of +3.2 days in hospital (p<0.001).

## Clinical Implications
- Routine glycaemic monitoring should extend to all inpatients, not just those with known diabetes.
- Dysglycaemia is a modifiable risk factor; active management of glucose targets may improve survival and reduce hospital resource burden.
