Brief Summary
Type 2 diabetes is a major problem of older people; its prevalence is greater than 20% in those aged over 65 years. Treatment such as medication, healthy nutritional choices \& body weight management, as well as physical activity can reduce the impact of diabetes. Older patients with type 2 diabetes can potentially benefit from Group Appointments, in which 8-12 patients share one appointment of about 60-120 minutes with a team of health professionals. The team of investigators (3 people) will see the 'Group' 4 times/yr for two years. Their key measure of success will be control of glycosylated hemoglobin - HbA1C. To address their primary and secondary research objectives the investigators will focus upon patients aged 65 years or older who have T2DM and who are being treated with oral hypoglycemic agents and diet, or diet alone. The investigators will compare patients randomized to (A) eight Group Appointments over a 24 month period (i.e., 4 per year), led by a primary care physician \[Intervention\] with, (B) patients randomized to eight traditional one-to-one usual care appointments also provided by a primary care physician (Individual Appointment; \[Control\]). The investigators will compare (A) and (B) on selected clinical, patient-rated, and economic outcome measures. SIGNIFICANCE: Seven Canadian provinces already have Group Appointment billing codes for physicians who lead Group Appointments. If the study's proposed health care innovation demonstrates benefits, it would be possible to 'roll out' / 'scale up' the model province- or nation-wide in Primary Care settings.

Outcome Measures
Primary Outcomes (1)
Patients' control (decreased levels) of HemoglobinA1C (clinical)
The investigators will measure Hemoglobin A1C (%, primary outcome), utilizing the phlebotomy unit in the CHHM Mobile Lab to collect a non-fasting blood sample (standard techniques). They will request that study participants not engage in any physical activity, or consume alcohol/caffeine 24 hours prior to measurement. Collected samples will be refrigerated in the Mobile Lab and transported the same day to the Vancouver General Hospital Pathology Lab for analysis as per current standard methods.

Individual Appointments (IAs)
ACTIVE COMPARATORParticipants randomly assigned to the "IAs" group will receive eight traditional 1-to-1 appointments, seeing their physician quarterly as per standard care in BC. They will be referred to ancillary services such as nutrition advice, counseling, and physical activity promotion according to 'usual care' practice. In addition, we will organize 4 1-hour social events for these participants annually. The 4 social events will be 1) a potluck lunch; 2) a movie night; 3) an event chosen by participants; and 4) a talent show. From our experience, these events enhance compliance to reporting and minimize dropouts. These events also serve to minimize 'socialization bias' that may otherwise potentially influence health measures including quality of life.
Group Appointments (GAs)
EXPERIMENTALParticipants randomly assigned to the intervention group will participate in GAs of 8 patients for 1.5 hours, every 3 months for 2 years. The 3-member Care Team (MD, nurse, behaviorist) will attend each session. The nurse facilitates the session and curriculum. The MD responds to specific health questions. Patients may schedule time before or after to review their clinical results with the MD/nurse (e.g. HbAIC). Key elements include 1) completed pre-appt questionnaires used to identify a patient's educational needs; 2) patients use goal setting and action plans to initiate and maintain healthy behaviors; 3) each class has a designated purpose and learning objectives; 4) sessional feedback, which is used to adapt the next class (3 months later) based on patient needs.
