Aims: To evaluate outcomes of diabetic inpatient hypoglycemia among Aboriginal and Torres Strait Islander (ATSI) compared with Australian Caucasian patients.

Methods: A retrospective audit of diabetic patients aged > 18 years admitted at a regional hospital general ward between April 1, 2015, and March 31, 2016, was analyzed. The database contains clinical information at the time of admission and initial discharge and readmission within 4 weeks thereafter.

Results: A total of 1618 (of 6027) patients were admitted with diabetes representing 23.7% of the total ward admissions, of which 484 (29.9%) had inpatient hypoglycemia. Of the 91 patients with available data analyzed, ATSI origin with inpatient hypoglycemia was associated with longer length of stay (LOS) (hazard ratio [HR], 2.1, 95% confidence interval [CI], 1.2-3.5), whereas severe hypoglycemia (≤ 2.2 mmol/L) in both ATSI and non-ATSI was significantly associated with longer LOS (HR, 2.3; 95% CI, 1.2-4.2). No significant differences in LOS were found for gender, age, and Carlson comorbidity index (CCI). The adjusted model for likelihood of readmission, gender, indigenous status, and CCI were not significant risk factors for readmission to the hospital. Readmitted patients were older (50-59 years vs < 50 years, P = 0.001; 60-69 years vs < 50 years, P = 0.032; 70+ years vs < 50 years, P = 0.031).

Conclusion: We reported high rate of inpatient hypoglycemia in our study population. Indigenous Australian diabetic patients with inpatient hypoglycemia had significantly longer LOS compared with non-Indigenous Caucasian counterparts. Further prospective studies on a larger population are needed to confirm our findings.
