- Brief Summary
Education for Equity (E4E)intervention intends to improve care delivery through a well designed educational program that address not only the issues of diabetes care delivery to Aboriginal patients with diabetes, but also the issues of effective cross-cultural and culturally safe communication between healthcare providers and Aboriginal patients, and the issues related to effective implementation of appropriate chronic disease management programs for Aboriginal patients in a range of practice settings. The purpose of this study is to evaluate the effectiveness of the E4E education program through measuring patient clinical outcomes, patient experience with their doctors, and the changes in physicians' approaches to care perceived by Aboriginal diabetic patients.
- Detailed Description
Two waves of the E4E intervention will be delivered to family physicians who have Aboriginal patients with type 2 diabetes on and off reserves. A mix-method approach will be employed in this evaluation study. Evaluation instruments include: (1) chart reviews and (2) patient experience surveys.
1. Chart review: A randomized, controlled, pre- and post intervention study design will be used to evaluate the effect of the E4E intervention on type 2 diabetes clinical outcomes of the Aboriginal patients. A retrospective chart audit will be used to gather the clinical data from 12 months prior to and 12 month after the intervention, not including the time during intervention.
Sample Size for chart review: The primary outcome measure of HbA1C value will be used to identify the impact of E4E intervention on the clinical outcome of Aboriginal patients with type 2 diabetes. It is hypothesized that the A1C value would be reduced in the E4E Intervention Group's patients whose A1C values are at or above 8.0% prior to the E4E intervention (baseline) compared to the patients in E4E Late Intervention Control Group. A 0.5% difference of patients' A1C values between these two groups will be a clinically significant difference. The sample size needed to detect such a difference is estimated to be 98 eligible patients charts with A1C at or above 8.0% from E4E Intervention Group and 98 eligible patient charts from E4E Late Intervention Control Group, with an a=0.05 and ß=0.15. Given the proportion of 61.1% of Aboriginal patients with type 2 diabetes having A1C at or above 8.0%, we need to review 163 patient charts to obtain 98 eligible charts from each group. When 10 charts extractions per physician are performed, we need 17 physicians from each group. Considering a possible 20% loss to follow up, we need to recruit 20 physicians from E4E Intervention Group and 20 physicians from E4E Late Intervention Control Group, a total of 40 physicians to be invited to participate in chart reviews.
Recruitment of physicians: After obtaining ethics approval from Queen's University Research Office, we will recruit 8-10 physicians to participate in the project at each potential site. Once recruitment is completed on each site, physicians will be randomized into E4E Intervention Group and E4E Late Intervention Control Group (sham comparator) who will participate in the second wave of E4E intervention 12 month later. Letters of information and consent form will be sent to the physicians to obtain their signed consent to participating in E4E chart review, patient survey and patient interview.
Data collection regarding chart reviews for diabetes: The evaluation team will require the consenting physicians to create a list of all of their Aboriginal patients with type 2 diabetes using billing code 250, removing non-Aboriginal patients. This process can either be managed by the practice (with staff being reimbursed for time required) or can be conducted by the research staff at time of the chart audit. Each physician will then be asked to review the list for accuracy. Random number generation will be used to select charts at random from the list until the required number of eligible patient charts has been identified. Chart reviewers will be trained staff from the evaluation team and travel to each selected location to conduct chart audits.
2. Patient experience survey: Two (2) patient experience surveys will be conducted to evaluate the experience of Aboriginal patient with type 2 diabetes with his/her physician, respectively at the point of 3-month after the E4E intervention and at the point of 12-month after the intervention.
Sample size for patient experience surveys: An effective sample size needed for patient experience survey, with an a=0.05 and power 85% (ß=0.15), is estimated to be 102 eligible Aboriginal type 2 diabetic patients from E4E Intervention Group and the same number of eligible Aboriginal patients from E4E Late Intervention Control Group. We will recruit 10 eligible Aboriginal patients from each of the physicians in E4E Group A and 10 eligible Aboriginal patients from each of the physicians in E4E Group B. A total of 400 patients will be recruited to participate in Patient Experience surveys. This sample size (200 from each group) is more than sufficient to achieve 85% power even after allowing for drop out of physicians and any unanticipated difficulties in patient recruitment.
Data collection regarding patient experience surveys: The Patient Experience Surveys will take approximately 15-20 minutes to complete and will be completed on the day of patient visit. Patient Experience Survey is designed in two sections: pre-visit section and post visit section. Consent needs to be obtained from patients in pre-visit section.
* The receptionist of the selected practice will notify eligible patients about the study, and ask if they are willing to discuss with support/research staff about participating in a Patient Experience Survey. If the patient is interested, the receptionist will refer her/him to the onsite support/research staff, or provide access to a private phone with toll free number to contact support/research staff.
* Support/Research staff will review the information letter with the patient and obtain informed consent.
* The patient completes the pre-visit section and sign on the consent before seeing the doctor.
* After seeing the doctor, the patient will be asked to complete the post-visit survey and return it to the support/research staff before leaving the clinic. For patients who are not able to do so, they will be offered a choice to complete the survey by toll free telephone or fill in a hard copy of questionnaire and mail it out by pre-paid mail.
* Regular updates will be performed during data collection process to keep tack of patients participation in the survey.

Group Intervention Description E4E Intervention Group E4E intervention E4E Intervention Group is a group of family physicians who will participate in the first wave of E4E intervention. E4E Late Intervention Control Group E4E intervention E4E Late Intervention Control Group is a group of family physicians who will participate in the second wave of E4E intervention 12 month later after the completion of the first wave of E4E intervention.
- Primary Outcome Measures
Name Time Method Hemoglobin A1C values--change is being assessed a 12-month period prior to the start of E4E intervention; a 12-month period post the completion of E4E intervention The primary outcome measure of A1C value will be used to identify the impact of the E4E program on clinical outcomes of Aboriginal patients with type 2 diabetes. It is hypothesized that the A1C value of the patients at or above 8.0% prior to their physicians' participation in the E4E intervention will be reduced since their physicians participate in the E4E intervention.
Cultural safety, bias and discrimination--change is being assessed within 2 weeks after the E4E workshop; 1 year later after completetion of E4E intervention Physicians' cultural safety, bias and discrimination will be measured with a Cultural Competence, Sensitivity and Discrimination scale\* from patients' perspectives. It is hypothesized that Aboriginal patients with type 2 diabetes will perceive increased cultural safety and decreased cultural bias/discrimination in their interactions with physicians since physicians participate in the E4E intervention.

Name Time Method Other laboratory tests (values and date)--change is being assessed a 12-month period prior to the start of the E4E intervention; a 12-month period after completion of the E4E intervention Frequency of other laboratory tests is an indicator of physicians' adherence to recommended control and prevention of complications. Test results are indicators of clinical outcomes of diabetes control in Aboriginal patients. The tests that will be examined are:
1. Triglycerides
2. HDL
3. LDL
4. Total cholesterol: HDL
5. Total cholesterol
6. eGFR/Creatinine Clearance
7. Serum Creatinine

It is hypothesized that adherence to recommended tests and test results will be improved since physicians participate in the E4E intervention.Diabetes process of care measures (date only)--change is being assessed a 12-month period prior to the start of E4E intervention; a 12-month period post the completion of E4E intervention Frequency of exams for complications of diabetes(eye, foot, ECG, waist circumference, neuropathy) is an indicator of quality of care related to physicians' adherence to diabetes care guidelines. It is hypothesized that the adherence to recommended screening for complications will be increased since physicians participate in the E4E intervention.
BMI (value, date)--change is being assessed a 12-month period prior to the start of E4E intervention; a 12-month period post the completion of E4E intervention Frequency of BMI check is an indicator of physicians' adherence to recommended diabetes control and prevention of complications. BMI values are an indicator of clinical outcomes of diabetes control in Aboriginal patients with type 2 diabetes. It is hypothesized that the adherence to BMI check will increased and BMI values will decrease since physicians participate in E4E intervention.
Documentation of self-management goals--change is being assessed a 12-month period prior to the start of E4E intervention; a 12-month period post the completion of E4E intervention Self-management goal is an indicator of efficacy of Aboriginal diabetic patients to self-management. It is hypothesized that Aboriginal patients with type 2 diabetes meet self-management goal better since their physicians participate in the E4E intervention.
Patient experiences of healthcare service (Canadian Institute of Health Information (CIHI) Patient Experience Survey)--change is being assessed within 2 weeks after the E4E workshop; 1 year later after the completion of E4E intervention Patients' healthcare experience will be assessed using the CIHI Patient Experience Survey\* and the Diabetes Empowerment Scale Short Form immediately after the E4E workshops being delivered and one year after the workshops. A co-primary outcome is Summary Patient Experience Score. It is hypothesized that Aboriginal patients will have better healthcare experiences with their physicians who participated in the E4E intervention.
