Implementation of a Multi-component, Supervised Exercise Program for Patients With Type 2 Diabetes Mellitus.

The Canadian Diabetes Association 2018 Clinical Practice Guidelines state that moderate to high levels of physical activity and cardiorespiratory fitness are associated with substantially lower morbidity and mortality in people with diabetes. The recommendations include a combination of aerobic, resistance, and flexibility exercises. The Guidelines specifically advocate for strategies that increase self-efficacy and motivation in order to increase physical activity uptake and maintenance.

Similarly, the importance of exercise counselling in primary care is widely recognized. Exercise is frequently identified as a key intervention for many chronic conditions, yet it remains under-prescribed. Physical activity counselling during routine diabetes care often takes a back seat to other issues, or lacks specific, actionable details that are important for patients to successfully integrate regular physical activity into their lifestyle. Moreover, even when prescribed, the successful implementation of physical activity behaviour changes remains a challenge for patients.

Eligible Rosemount Family Health Organization adult patients age >=18 years with type 2 diabetes mellitus will receive an email or mail invitation to self-refer to a structured, facility-based, supervised aerobic and resistance exercise program. Interested patients will be invited to attend a 1-hour information session at the exercise facility at the time of implementation start up where they will complete an initial survey. Patients will then be free to attend up to 6 regularly-scheduled, group, free classes per week at a local exercise facility for a period of 3-months. Classes will be supervised by experienced trainers.

Measures of program success will focus around four themes, informed in part by the Institute for Healthcare Improvement's Triple Aim: (i) adherence to CDA guidelines for physical activity, (ii) patient experience, and (iii) health impact. Our balancing measure will be potential costs incurred by patients. Adherence measures, including percentage uptake (i.e. attend introductory session and one class), retention (at 1, 2 and 3-months), and percentage who meet CDA recommendations for exercise will be collected. Reasons for declined or discontinued participation will also be collected voluntarily from patients to help identify concrete or perceived barriers to structured exercise programs. Health-related measures will include quality of life (EQ-5D-5L) and exercise self-efficacy (Basic Psychological Needs in Exercise Scale, BP-NES). These will be measured by patient-report at 0, 1, 2, and 3-months. Participants will be asked to rate their "willingness to recommend" (Likert scale 1-10) the program to other individuals with T2DM. Additionally, pre- and post-exercise program hemoglobin A1c and blood pressure measurements (both of which are routinely collected for all patients with T2DM) will be obtained from patient charts. Finally, while this program will be free to patients, a hypothetical cost per patient will be estimated in order to gain an understanding of the financial costs compared to the value added through patient experience and health outcome measures.
