Study Arms:
- Sitagliptin + glargine (Hospital) (Type: EXPERIMENTAL): Sitagliptin and glargine once daily + correction doses of aspart or lispro if needed
- Basal bolus (Hospital) (Type: ACTIVE_COMPARATOR): Glargine once daily and rapid-acting insulin before meals + correction doses of aspart or lispro if needed
- Metformin and Sitagliptin (Type: EXPERIMENTAL): Patients with HbA1c ≤ 7% will be discharged on the combination of metformin and sitagliptin (Janumet ® 500/50 mg) twice daily for 6 months
- Metformin and sitagliptin + glargine 50% (Type: EXPERIMENTAL): Patients with HbA1c between 7% and 9% will be discharged on metformin and sitagliptin (Janumet ® 500/50 mg) twice daily plus glargine insulin (50% of the inpatient glargine dose) for 6 months
