|Condition or disease||Intervention/treatment||Phase|
|Type 2 Diabetes||Behavioral: Nurse Case Management Behavioral: standard diabetologist care||Not Applicable|
The study will be a randomized-control trial recruiting patients with type 2 diabetes in a specialty care setting from two sources:
- referred by family physicians with inadequate glycemic control likely requiring exogenous insulin therapy
- referred by medical staff at Vancouver General Hospital or St. Paul's Hospital during in-patient care & about to be discharged (Appendix 1).
Patients who meet the inclusion criteria will be randomly assigned into either the NCM group or SC group.

- A1c [ Time Frame: 6 months ]changes in A1C between NCM vs. SC
- diabetes distress (DDS) [ Time Frame: 6 months ]changes in diabetes distress between NCM vs. SC. Diabetes Distress (DDS) will be assessed using the 17-item Diabetes Distress Scale (DDS) developed by Polonsky and colleagues. The DDS measures emotional distress and functioning as it relates to living with diabetes. Responses are scored on a 6-point Likert scale (1=no problem to 6=serious problem). A total score is derived by taking the mean of all items. A score of < 2 indicate low/no distress, 2 - 2.9 indicates moderate distress, and score of ≥ 3 indicates high distress.
- blood pressure [ Time Frame: 6 months ]changes in BP between NCM vs. SC. Blood pressure will be measured using an Omron Digital Blood Pressure Monitor HEM-907. Two upper arm readings are taken with the average of the two recorded.
- BMI [ Time Frame: 6 months ]changes in BMI between NCM vs. SC. Height and weight will be measured using the Healthometer mechanical eye level upright standard physician scale with attached stadiometer. Body mass index (BMI) are calculated as weight in kilograms divided by height in meters squared.
- Self-management behaviours [ Time Frame: 6 months ]changes in behaviour habits between NCM vs. SC. Self-management behaviours will be assessed using items from the Summary of Diabetes Self-Care Activities Measure-revised (SDSCA-R).This instrument measures self-care behaviors including diet, exercise, blood sugar testing and foot care. Participants are asked to report the number of days in the past week (range 0-7 days) in which he/she performed specific self-care practices. Greater number of days indicates better self-management.
- Medication adherence [ Time Frame: 6 months ]changes in medication adherence between NCM vs. SC. Medication adherence will be assessed using the 4-item Moriskyscale that assesses beliefs and behaviors associated with taking medications.Responses are scored on a dichotomous scale: 0=no and 1=yes. A total score is calculated by adding up all items with lower scored indicating better adherence.
- Patient motivation [ Time Frame: 6 months ]change in patient motivation between NCM vs. SC. motivation will be measured by the 13-item Patient Activation Measure which assesses participants' self-reported knowledge, skills, and confidence an individual has when managing his/her own health.
- Diabetes-specific Social Support [ Time Frame: 6 months ]change in diabetes-specific social support between NCM vs. SC Diabetes-specific Social Support will be assessed with a 4-item scale developed by Tang et al. that measures amount of support and satisfaction with support from family, friends and the health care team.
- Depressive Symptoms Severity [ Time Frame: 6 months ]change in depressive symptoms between NCM vs. SC Depressive Symptom Severity will be assessed using the 9-item PRIME-MD Patient Health Questionnaire (PHQ-9)
