This study will examine whether patients with diabetes who are either 1) newly discharged from hospital or 2) referred to an endocrinologist for management will have better diabetes outcomes when their care is managed primarily by a dedicated case manager (intervention) than by an endocrinologist (standard care) after 6 months of treatment.

    achievement of A1c < 7.0

  • LDL cholesterol [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    target LDL <2.0 mmol/L (=76 mg/dl)

  • blood pressure [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    < 140/90

Detailed Description:

The study will be a randomized-control trial recruiting patients with type 2 diabetes in a specialty care setting from two sources:

  1. referred by family physicians with inadequate glycemic control likely requiring exogenous insulin therapy
  2. 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. Primary and secondary data, including A1C, fasting glucose, lipid profile, eGFR, blood pressure, BMI, self-report measures, adherence to annual eye exam/vaccination, emergency visits and hospital stays will be collected at baseline, 3-months (only for NCM group), and 6 months.

Study Population Number of Patients The literature suggests the probability of meeting targets on all three outcomes is about 10% in the control group and about 22% in the treatment group. In order to detect this increase in probability of success in all three groups with an 80% power and a 5% significance level, we require 146 patients per group. Since the analysis will include a factor for recruitment location as well as some other baseline covariates, we will recruit an additional 9 patients per group to cover lost power due to these nuisance parameters in the model. In total we will recruit 310 patients split equally between treatment and control.
