Comprehensive Intervention to Evaluate Outcomes AND Cost in Hospitalized Surgical Patients With Diabetes Mellitus (DM)

All patients who are planned for elective surgery at the hospital are seen in the pre-operative center a few days before admission. The diabetes management team becomes involved in care of patients with HbA1c >8.0% at this time. Once the patients are admitted to the hospital, the diabetes management team continues to follow them until they are ready for discharge. At the point of discharge, patients are randomized to one of two arms- the usual care group and the expanded diabetes management service (eDMS). The eDMS group is followed closely for 1 year after discharge by the investigators to make sure they receive appropriate care for their diabetes.

Aims of this study are:

• To evaluate whether patients that receive the eDMS have lower re-hospitalization rates at 1 month compared to patients who receive the traditional (current) DMS. Investigators hypothesize that the eDMS program will have lower re-hospitalization rates at 1 month.
• To evaluate whether patients that receive the eDMS have lower HbA1c levels at 1 year compared with patients who receive the traditional DMS. Investigators hypothesize that patients in the eDMS program will have lower HbA1c levels and improved diabetes-related health outcomes after 1 year in the program.
