The hypothesis of this study is that using hospital admission to identify patients with poorly controlled diabetes (hemoglobin A1c levels >8%), and intervening during the hospitalization with targeted inpatient diabetes management will improve glycemic control at 3 and 12 months, with inpatient glycemic control, quality of life, and diabetes self-efficacy serving as secondary endpoints.

Primary Outcome Measures:
  • Hemoglobin A1c [ Time Frame: 6 months from discharge ]
    Change in glycemic control measured by HbA1c change baseline to 6 months

Secondary Outcome Measures:

Study Completion Date: July 2011
Primary Completion Date: July 2011 (Final data collection date for primary outcome measure)

Experimental: Diabetes Management Team
Evaluation and management by diabetes management team
Other: Diabetes management team
MD evaluation followed by NP education and and medication titration
No Intervention: Control
Patients receive usual care for diabetes

Detailed Description:
The study is a randomized, controlled trial of targeted inpatient diabetes management versus usual care in 70 general medical and surgical inpatients over age 18 with type 2 diabetes and hemoglobin A1c levels greater than 8% who are followed in Partners-affiliated primary care practices. In addition, we will enroll a prospective chart review cohort matched for age, sex, and HbA1c level whose course we will follow for one year after discharge to determine the patter of glycemia among patients who are not enrolled in a clinical trial.

Accepts Healthy Volunteers:   No

Inclusion Criteria:

Exclusion Criteria:

  • Screening HbA1c returns less than 8%.
  • Diabetic ketoacidosis (DKA) as a primary reason for admission (admission blood glucose > 250 mg/dl with arterial pH < 7.30 or serum bicarbonate level < 15 mg/dl), or development of DKA during admission.
  • Hyperosmolar hyperglycemic syndrome as a primary reason for admission (admission blood glucose > 400 mg/dl and plasma osmolality > 315 mOsm/kg.
  • Pregnancy, ruled out by urine HCG test at screening after consent is obtained in all women who continue to have menstrual cycles.
  • Anemia with hemoglobin < 9 g/dl, recent blood transfusion, or need for blood transfusion (interferes with interpretation of hemoglobin A1c assay)

  • Treatment with corticosteroids
  • ICU transfer
  • Inability to self-administer insulin
  • Hypoglycemia unawareness: patient lacks sensation of common signs of blood glucose < 60 mg/dl (tachycardia, diaphoresis, hunger, confusion, fatigue).
  • Projected survival < 1 year
