Factors Associated with Incidence of Hyperglycemia.

Variable	IRR (95% CI) ‡	p-value
Insulin Pump use	0.79 (0.65–0.96)	0.02
Diabetes Type 1 vs Type 2	1.40 (1.13–1.72)	0.002
Hemoglobin A1c (%)	1.11 (1.06–1.16)	<0.0001
Blood glucose on admission (per 10 mg/dL)	1.03 (1.02–1.04)	<0.0001

^‡IRR (Incidence Rate Ratio) estimated via Negative Binomial Regression. This model considered the following variables: insulin pump use, sex, diabetes type, steroid use, hemoglobin A1c, admission creatinine, admission glucose.
