Implementation of a Multi-component, Supervised Exercise Program for Patients With Type 2 Diabetes Mellitus From a Primary Care Practice: A Quality Improvement Study.

This quality improvement study aims to implement a supervised, multi-component exercise program for patients type 2 diabetes mellitus (T2DM) from a primary care practice. Rosemount Clinic patients with T2DM will be invited to participate in free group exercise classes as part of a 3-month program of structured exercise to enhance adherence to the Canadian Diabetes Association (CDA) clinical best practice guidelines. Interested patients will attend an initial 1-hour information session and then will complete short, monthly questionnaires about their current quality of life and experience with the exercise program. Participation is voluntary and patients may drop out at any time.

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.

Structured, multi-component, supervised group exercise classes are the health related intervention proposed for this study. The group classes will occur at a local CrossFit gym facility. For the purposes of this project, all eligible Rosemount Clinic patients with type 2 diabetes mellitus will receive an email or letter 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 baseline survey. This session will also serve as an initial meet and greet for participants to meet exercise trainers prior to starting exercise classes and to receive a tour of the facility.

The group classes will occur at a local CrossFit gym facility. Participants will be free to attend up to 6 regularly-scheduled, free, 1-hr group classes per week at the local exercise facility for a period of 3-months. The recommendation will be to aim to attend at least three classes/week but there will no prescribed minimum. Classes will be supervised by experienced trainers. Trainers will work collaboratively with participants to adapt the skill and workout of the day within each group class to the individual participant's physical limitations and needs. As such, each participant may complete a slightly different movement or workout on any given day based on their functional status at that time. However, all participants will be actively included in the community of the group class and will experience a relative stimulus that is moderately challenging for them.

Percentage of participants who meet or exceed Canadian Diabetes Association guideline recommendations for exercise in type 2 diabetes

Change from baseline in 5-level EuroQol-5 Domain score (this is a quality of life scale where higher values indicate better quality of life) with Canadian index scores ranging from -0.148 (worst state) to 0.949 (best state).

Change from baseline in Basic Psychological Needs in Exercise Scale (measuring basic psychological needs in healthy physical exercise) score with scores ranging from 11 (worst) to 55 (best) (in other words higher scores indicate that needs are better met).

Participants will be asked to rate their "willingness to recommend" (Likert scale) the program to other individuals with type 2 diabetes (this is a 10-point scale where higher values indicate higher likelihood to recommend).

Baseline and post-intervention blood pressure measurements will be obtained from patient charts, as routinely collected during type 2 diabetes care every 3-months.

Baseline and post-intervention hemoglobin A1c measurements will be obtained from patient charts, as routinely collected during type 2 diabetes care every 3-months.

Inclusion Criteria: Adult (age >= 18 years) patients rostered with one of the Rosemount Clinic physicians with a clinical diagnosis of type 2 diabetes mellitus (fasting plasma glucose of >= 7.0 mmol/L, a 2-hour plasma glucose value in a 75 g oral glucose tolerance test of >= 11.1 mmol/L or a glycated hemoglobin (A1C) of >= 6.5%). Exclusion Criteria: Exclusion criteria are primarily based off of those employed in the Look AHEAD (Action for Health in Diabetes) trial.
