Impact of a Comprehensive Guideline Dissemination Strategy on Diabetes Diagnostic Test Rates: an Interrupted Time Series.

BACKGROUND: Diabetes Canada launched a comprehensive Dissemination and Implementation (D&I) strategy to optimize uptake of their 2013 Clinical Practice Guidelines; the strategy involved continuing professional development courses, webinars, an interactive website, applications for mobile devices, point-of-care decision support tools, and media awareness campaigns. It included a focus on promoting HbA1c as the recommended diagnostic test for diabetes. OBJECTIVE: To determine the impact of Diabetes Canada's 2013 D&I strategy on physician test-ordering behavior, specifically HbA1c testing, for the diagnosis of diabetes, using provincial healthcare administrative data. DESIGN: Population-based interrupted time series. SETTING: Ontario, Canada. PARTICIPANTS: Ontario residents aged 40-79 not previously diagnosed with diabetes. MEASUREMENTS: For each quarter between January 2005 and December 2014, we conducted an interrupted time series analysis on the first-order difference of the proportion of patients receiving HbA1c tests per quarter with an autoregressive integrated moving average model with the intervention step occurring in quarter 2 of 2013. Subgroup analyses by rurality, physician graduation year, and practice size were also conducted. RESULTS: There were 32 quarters pre-intervention and 6 post-intervention; average sample size per quarter was 5,298,686 individuals. Pre-intervention, the quarter-to-quarter growth was 1.51 HbA1c tests per quarter per 1000 people. Post-intervention, the quarter-to-quarter growth increased by 8.45 tests per 1000 people (p < 0.005). Growth of HbA1c ordering differed significantly by region, years since physician graduation, and practice size. LIMITATIONS: Incomplete data collection, inadequate stratification, and other unidentified confounders. CONCLUSION: The D&I strategy resulted in a significant increase in the growth of HbA1c tests. The successful uptake of this recommendation may be due to its simplicity; guideline developers should consider this when drafting recommendations. Furthermore, differential uptake by user groups suggests that future strategies should include targeted barrier analysis and interventions to these groups.

Process Evaluation of the Diabetes Canada Guidelines Dissemination Strategy Using the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) Framework.

OBJECTIVES: Our purpose was to disseminate and implement the Diabetes Canada (formerly the Canadian Diabetes Association) 2013 Clinical Practice Guidelines and evaluate the impact of the dissemination and implementation strategy on process outcomes (reach, adoption, implementation and maintenance). METHODS: Our patient- and provider-directed strategy consisted of a guidelines website, electronic point-of-care decision-support tools, mobile applications, electronic medical record templates, laboratory prompts, continuing professional development modules, a communications campaign and printed education materials. We used the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) framework to assess process-level outcomes. We report on the reach, adoption, implementation and organizational maintenance by using mixed methods and multiple data sources (communications reports, mailing lists, website-usage statistics, accreditation logs, session-evaluation forms, budgets). RESULTS: A total of 1,786,910 contacts were made with health-care professionals, the majority of whom were nurses. The greatest reach was through the website. A total of 35,573,154 contacts were made with the general population; the greatest reach occurred through media channels. We contacted 149 and collaborated with 18 governmental, professional and health advocacy organizations about activities such as distributing resources and implementing team-based care initiatives and screening policies. Most website users were young women, with use occurring during working hours. Interactive clinical decision-support tools were most commonly accessed. Website use increased with time. The institutionalization of guidelines occurred in a few areas such as the use of an adapted screening policy in the Northwest Territories. CONCLUSIONS: Our interactive tools were repeatedly accessed, signifying their relevance to problems in clinical care. Our synthesized analyses indicate that the guidelines website is resource intensive, with a wide reach and the potential to change outcomes.

Positioning the Value of Dietary Carbohydrate, Carbohydrate Quality, Glycemic Index, and GI Labelling to the Canadian Consumer for Improving Dietary Patterns.

The objectives of this qualitative study was to: (1) understand Canadian consumers' knowledge and perception of dietary carbohydrates, carbohydrate quality, and the glycemic index (GI); and (2) determine Canadian's receptiveness to GI labelling to assist with identifying and consuming foods of higher carbohydrate quality. Focus groups were recruited in Vancouver, Toronto, and Montreal and grouped according to body mass index (BMI) (NBW, normal body weight; PO, previously obese; and OW/OB, overweight/obese) and diagnosis with prediabetes and diabetes (PO (Vancouver) and OW/OB (Montreal and Toronto). Subjects in all groups linked excess consumption of carbohydrate with weight gain. PO and OW/OB groups were conflicted between perceived negative consequences and feelings of pleasure associated with carbohydrate consumption. Subjects were largely unfamiliar with the term 'carbohydrate quality', but were often associated with classifying carbohydrates as 'good' or 'bad'. The concept of the GI resonated well across groups after exposure to corresponding educational materials. However, NBW groups largely felt that the GI was irrelevant to their dietary choices as they did not have a history of diabetes. PO and OW/OB groups associated the GI with diabetes management. The concept of a GI labelling program to help facilitate healthier carbohydrate choices was well received across all groups, especially when the low GI was interpreted as giving permission to consume foods they enjoyed eating. Results suggest that the GI could be used as a consumer-facing labelling program in Canada and assist with de-stigmatizing carbohydrate foods by helping to facilitate the consumption of carbohydrate foods that align with healthy dietary patterns.

A Canadian Cross-Sectional Survey on Psychosocial Supports for Adults Living With Type 1 or 2 Diabetes: Health-Care Providers' Awareness, Capacity and Motivation.

OBJECTIVES: Addressing psychosocial issues is critical for diabetes self-management. This work explores health-care professionals' (HCPs') 1) perceived relevance of various psychosocial issues in diabetes management and 2) confidence in working on these issues within their services. METHODS: An online cross-sectional survey was developed based on the Capacity-Opportunity-Motivation Behaviour Model. It assessed self-rated confidence in supporting patients with psychosocial issues (capability), perceived relevance of these issues (motivation) and facilitators of skill development (opportunity). An e-mail invitation was sent to all Diabetes Canada's professional members, conference delegates and committee members. Qualitative responses were analyzed using thematic analysis. RESULTS: Of the 260 responses received (25% response rate), many were Diabetes Canada professional members (83%) and/or certified diabetes educators (66%). The largest professional groups in the sample were registered nurses (44%) and registered dietitians (33%). All psychosocial issues were perceived as somewhat or extremely important by at least 80% of respondents (range, 80% to 97%). However, HCPs were less confident in supporting their patients with these psychosocial issues; significantly fewer respondents reported that they felt somewhat or extremely confident (range, 26% to 62%). Depression (80%) and anxiety (80%) were the issues in which guidance was most desired. Most respondents wanted some form of formal self-management support training (83%). Preferred training methods included in-person workshops (56%), webinars (56%) and conference sessions (51%). CONCLUSIONS: Motivation to address psychosocial issues in diabetes was high, but capacity to do so and opportunity to learn how were both low. These findings can be used to develop a targeted strategy to help address this gap.

Impact of the Canadian Diabetes Association guideline dissemination strategy on clinician knowledge and behaviour change outcomes.

AIM: Implementation of clinical practice guideline (CPG) into clinical practice remains limited. Using the Knowledge-To-Action framework, a guideline dissemination and implementation strategy for the Canadian Diabetes Association's 2013 CPG was developed and launched to clinicians and people with diabetes. METHODS: The RE-AIM framework guided evaluation of this strategy clinician; we report here one aspect of the effectiveness dimension using mixed methods. We measured impact of the strategy on clinican knowledge and behaviour change constructs using evaluation forms, national online survey and individual interviews. RESULTS: After attending a lecture, clinician confidence (n = 915) increased (3.7(SD 0.7) to 4.5 (SD 0.6) on a 5-point scale (p < 0.001)), with 55% (n = 505) intending to make a practice change (e.g. clinical management regarding glycemic control). Ninety-four percent of survey respondents (n = 907) were aware of the guidelines, attributed to communications from professional associations, continuing professional development events, and colleagues. Forty to 98% of respondents (total n 462-485) were correct in their interpretation of CPG messages, and 33-65%(total n 351-651) reported that they had made changes to their practice. Interviews with 28 clinicians revealed that organizational credibility, online access to tools, clarity of tool content, and education sessions facilitated uptake; lack of time, team-based consensus, and seamless integration into care and patient complexity were barriers. CONCLUSION: The complexity of diabetes care requires systemic adoption of organization of care interventions, including interprofessional collaboration and consensus. Augmenting our strategy to include scalable models for professional development, integration of guidelines into electronic medical records, and expansion of our target audience to include health care teams and patients, may optimize guideline uptake.
