Table 1 Fit statistics for non-medical knowledge questions from pilot study (phase 2) merged data. Item 17 demonstrates mild misfit

1. How many problems per patient do you believe impairs your ability to manage inpatient glycemia?

2. How many patients under your individual care do you believe impairs your ability to manage inpatient glycemia?

3. How much time (in hours) would you estimate is spent discussing inpatient glycemic control on teaching rounds each week while on an inpatient medicine service?

4. How much time (in hours) would you estimate is spent discussing or managing diabetes in your outpatient continuity clinic across one month (4 clinic sessions)?

5. As the number of problems per patient or total number of patients under my individual care begins to make me feel uncomfortable, my ability to appropriately manage inpatient glycemia is impaired?

6. I feel that I have received adequate education and preparation for managing inpatient glycemia

7. I feel that I am too busy and have too many other responsibilities to adequately manage inpatient glycemia as a resident on an inpatient medicine service

8. I feel comfortable treating and managing inpatient hyperglycemia

9. I feel comfortable with my knowledge of basal plus bolus subcutaneous insulin regimens

14. I believe that fear of causing hypoglycemia is a barrier to successful inpatient glycemic control

15. I believe that lack of knowledge of how to best treat hypoglycemia is a barrier to successful inpatient glycemic control

16. I believe that lack of knowledge of basal plus bolus insulin regimens is a barrier to successful inpatient glycemic control

17. I believe that unpredictable mealtimes and/or patient noncompliance with diet is a barrier to successful inpatient glycemic control

18. I believe that lack of discussion about glucose management on teaching rounds is a barrier to successful inpatient glycemic control

19. I believe that cross-coverage and handoffs between residents is a barrier to successful inpatient glycemic control
