Diabetic ketoacidosis in patients with type 2 diabetes: Risk factors for mortality and adverse outcomes

Table 3 Predictors of length of hospital stay

Predictor	Coefficient	95%CI	P value	Interpretation
Intercept	-19.14	(-110.98 to 72.70)	0.679	Baseline length of stay (reference group)
Cerebrovascular disease	6.75	(0.76 to 12.74)	0.028	Adds about 6.7 days to LOS
Those who were on SGLT-2 inhibitors	5.80	(1.32 to 9.62)	0.035	Adds about 5.8 days to LOS
COPD	3.60	(2.14 to 6.44)	0.04	Adds about 3.6 days to LOS
Higher NEWS 2 score	1.14	(0.10 to 2.18)	0.033	Each NEWS 2 point adds about 1.14 days to LOS
Systolic BP	-0.18	(-0.32 to -0.04)	0.014	Lower systolic BP predicts longer LOS
Acute myocardial infarction	-6.06	(-12.15 to 0.03)	0.051	Shortens LOS by about 6 days (only borderline significance as P > 0.05 and confidence interval crosses 0)

NEWS: National early warning score; BP: Blood pressure; SGLT: Sodium glucose co-transporter; LOS: Length of stay; COPD: Chronic obstructive pulmonary disease.
