Brief Summary

Chronic disease management programs are shown to reduce mortality, recurrent hospitalizations, and improve indirect societal costs among specific subgroups of the population. INTERxVENT is one such individualized chronic cardiovascular and lifestyle management program, comprised of several individualized modules - diet, exercise, stress management, smoking cessation, chronic disease - prescribed algorithmically according to patient risk profile, environmental surroundings, and behavioural readiness-to-change. Nonrandomized studies assessing INTERxVENT in diabetic, pre-diabetic, and metabolic syndrome populations have demonstrated improvement in several intermediary endpoints, including reductions in fasting glucose, lipids, and blood pressure. However, no randomized controlled clinical trials in these populations have been conducted. This pilot study is a randomized clinical trial evaluating the effectiveness of INTERxVENT as compared with 'usual medical care' in improving cardiovascular risk-factor profiles among individuals with diabetes. Additionally, the extent to which such findings are generalizable to diabetic, socially vulnerable, populations is unknown, thus this will be examined also.

Outcome Measures

Primary Outcomes (1)

  • Six-month United Kingdom Prospective Diabetes Study (UKPDS) risk engine score. The UKPDS risk engine is a validated scoring system that uses multiple clinical characteristics to predict new coronary heart disease risks in patients with type 2 diabetes.

    6 months

Secondary Outcomes (1)

  • Six-month: HbA1c, seated systolic blood pressure, serum Total Cholesterol concentration, serum HDL-C concentration, Total/HDL-C ratio value, LDL-C concentration, self-reported smoking status, adherence to medications and lifestyle measures.

    6 months

Study Arms (2)

INTERxVENT Program

EXPERIMENTAL

Participants in INTERxVENT will complete a 'Baseline Assessment' and 'Follow-up' questionnaire, and will have a health professional visit his/her home for an initial assessment (BP,height,weight,waist measurement) and blood collection (blood glucose and cholesterol levels). As part of the program, each participant will also complete a self-reported 'Health History Questionnaire' (HHQ); a follow-up HHQ will be completed about 12 weeks into the program to monitor progress. Each participant randomized to INTERxVENT receives educational articles which address diabetes management issues. A structured, individualized program, consisting of educational materials and 12 live mentoring/coaching telephone calls will take place over 6 months. The mentors consist of allied health professionals. The sequence by which educational content is administered will be both self-directed and guided by the mentors using an algorithmic approach according to the participant's readiness-to-change scores.

Behavioral: INTERxVENT lifestyle modification program

Usual medical care

NO INTERVENTION

Each participant randomized to this group will not receive any formal intervention but will receive the same care over the 6-month period as he/she usually receives from his/her health care team. Participants in this group will undergo the same baseline and outcome assessment as those in the intervention group, including blood pressure (BP) measurement, physical assessment (height, weight, waist measurement) and blood collection (blood glucose and cholesterol levels), as well as completion of the 'Baseline Assessment' and 'Follow-up' questionnaires.

Interventions

It is a lifestyle behavior modification program which helps Type 2 diabetics manage diabetes better and reduce cardiovascular risk factors. The program involves up to 12 telephone mentor/coaching sessions with a certified health professional.
