Implementation of resources to support patient physical activity through diabetes centres in Atlantic Canada: the effectiveness of toolkit-based physical activity counselling.

OBJECTIVE: The purpose of this study was to determine the effectiveness of toolkit-based physical activity counselling on physical activity and exercise participation of type 2 diabetes patients attending diabetes centres in Atlantic Canada. METHODS: Patients with type 2 diabetes (n=198) were recruited to a quasiexperimental study comparing the effectiveness of counselling by persons trained to use a physical activity and exercise resource manual (i.e. toolkit) vs. a standard of care counselling situation. Effectiveness was assessed through questionnaires completed by patients, and clinical data were extracted from patient charts before and 6 months after a single appointment with a diabetes educator. Primary outcome measures were patient self-reported physical activity and exercise levels, efficacy perceptions and mean glycated hemoglobin. RESULTS: There were no significant differences in primary outcomes over time. Subanalyses of the toolkit-counselled patients revealed a significant interaction for moderate-to-vigorous physical activity (MVPA [p<0.0001]), whereby patients who were not meeting Canadian Diabetes Association guidelines for physical activity at baseline (i.e. <150 MVPA a week; n=44) increased physical activity (from 20±23 to 120±30 minutes) and patients who were active at baseline (i.e. >150 MVPA a week; n=22) decreased physical activity (from 444±32 to 161±41 minutes) at 6 months. CONCLUSIONS: A single counselling appointment using the toolkit did not elicit significant changes in physical activity or clinical outcomes measured 6 months later when compared with standard care condition; however, increased physical activity was observed for patients who were inactive at baseline. Repeated counselling or more intensive strategies may be required to increase patient physical activity levels and produce clinical outcomes.

Implementation of resources to support patient physical activity through diabetes centres in Nova Scotia: the effectiveness of enhanced support for exercise participation.

OBJECTIVE: The purpose of this study was to determine the effectiveness of enhancing support for physical activity counselling and exercise participation at diabetes centres in Nova Scotia on physical activity and exercise behaviours and clinical outcomes in patients with type 2 diabetes mellitus. METHODS: In all, 180 patients at 8 diabetes centres participated in this observational study. A range of enhanced supports for exercise were offered at these centres. A kinesiologist was added to the diabetes care team to primarily provide extra physical activity counselling and exercise classes. Patient physical activity and exercise levels, efficacy perceptions and mean glycated hemoglobin (A1C) were evaluated at baseline and 6 months. We compared changes in these variables for patients who participated in the enhanced supports versus patients who did not. RESULTS: Participants who attended exercise classes (n=46), increased moderate physical activity by 27% and doubled resistance exercise participation (1.0±1.8 to 2.0±2.1 days per week) whereas those who did not attend exercise classes (n=49) reduced moderate physical activity by 26% and did not change resistance exercise participation (interactions, p=0.04 and p=0.07, respectively). Patients who received resistance band instruction (n=15) from a kinesiologist had reductions in A1C (from 7.5±1.4 to 7.1±1.2; p=0.04), whereas other subgroups did not have significant changes in A1C. CONCLUSIONS: Offering enhanced support for exercise at diabetes centres produced improvements in physical activity and exercise in type 2 diabetes patients. Resistance band instruction from a kinesiologist combined with participating in a walking and resistance training program improved glycemic control, which underscores the importance of including exercise professionals in diabetes management.

Profile of adults with type 2 diabetes and uptake of clinical care best practices: results from the 2011 Survey on Living with Chronic Diseases in Canada - Diabetes component.

AIMS: This study aimed to (1) describe the profile of adults with type 2 diabetes (T2D) in Canada and (2) assess the uptake of clinical care best practices, as defined by the Canadian Diabetes Association (CDA) Clinical Practice Guidelines (CPGs). METHODS: We used data from the 2011 Survey on Living with Chronic Diseases in Canada - Diabetes component. Participants were aged 20 years and older, living in the 10 Canadian provinces, with self-reported T2D. Descriptive analyses present the prevalence of complications and comorbidities, as well as the level of clinical monitoring and self-monitoring/lifestyle management recommendations participants received. RESULTS: We included 2335 participants with T2D, a mean age of 62.9 years, and high prevalence of complications/comorbidities and prescription medication use. Most participants reported being monitored as recommended for eye disease (73.9%), weight (81.0%), blood pressure (89.0%) and blood cholesterol levels (94.3%), but only 65.5% reported having at least two HbA1c tests during the last year and 46.5% reported an annual foot examination by a health professional. About two-thirds of the participants reported having received recommendations on weight management (59.9%) and physical activity (64.7%) from a health professional in the previous year; only 47.8% of the participants reported having received diet counseling to improve diabetes control. CONCLUSION: Although the uptake of CDA CPGs for clinical and self-monitoring was high, with the majority of the participants reporting meeting most indicators, it was lower for HbA1c measurement and foot examination. Uptake of lifestyle management recommendations provided by health professionals was also significantly lower.

Increasing diabetes educators' confidence in physical activity and exercise counselling: the effectiveness of the "physical activity and exercise toolkit" training intervention.

OBJECTIVE: The objective of this action research was to examine the effectiveness of a comprehensive intervention (the toolkit) in improving diabetes educators' (DEs') perceptions of their abilities and their patients' abilities related to physical activity as part of regular diabetes self-management. METHODS: Two separate studies were conducted. Participants completed measures assessing confidence, attitudes and perceived difficulty. In study 1, a quasi-experimental design was used to examine the impact of the training intervention at 6 months. Cross-sectional sampling at baseline and 12 months then was used to assess the longer-term impact of the intervention. In study 2, a pre-post design was used to test the impact of the intervention at 12-months in a separate sample. RESULTS: The primary finding was a consistent increase in DEs' confidence in their ability to provide physical activity and exercise counselling with increases of up to 20% after the training intervention. Furthermore, DEs reported greater knowledge about physical activity (p<0.03) yet perceived physical activity counselling to be more difficult after receiving the training (p<0.05). In study 2, the DEs reported increases in perceived patient knowledge and confidence in their patients (p<0.03) after the intervention. Secondary analyses showed that frequently referring to the toolkit was associated with higher counselling efficacy and lower perceived difficulty (p<0.03). CONCLUSIONS: These findings suggest that the toolkit is an effective resource to improve DEs' confidence in the area of physical activity counselling. As a result of this work, the toolkit has been adopted as standard diabetes care across Nova Scotia and as a foundational resource for DEs across Canada.

Self-monitoring of blood glucose in type 2 diabetes: Results of the 2011 Survey on Living with Chronic Diseases in Canada.

BACKGROUND: For insulin-treated patients with type 2 diabetes mellitus (T2DM), self-monitoring of blood glucose (SMBG) may be vital in adjusting insulin dosages. For patients who do not use insulin, evidence supporting the use of SMBG is inconclusive. METHODS: The prevalence, frequency and correlates of SMBG are examined. Data pertain to 2,682 individuals aged 20 or older with T2DM who responded to the 2011 Survey on Living with Chronic Diseases in Canada. Multivariate prevalence rate ratios for associations between respondents' characteristics and their use of SMBG were derived using binomial regression models. RESULTS: A large majority of the study population (87.8%) reported SMBG. No difference in the prevalence of SMBG was observed between oral medication users compared with insulin users; however, the frequency of SMBG was lower for those taking oral medication only. Significant determinants of SMBG were a health professional's recommendation, having insurance coverage, and receiving an A1C test from a health professional. INTERPRETATION: The use of SMBG by adults with T2DM is common, and does not differ between those taking oral medication only and those treated with insulin.

Evidence-informed guidelines for treating frail older adults with type 2 diabetes: from the Diabetes Care Program of Nova Scotia (DCPNS) and the Palliative and Therapeutic Harmonization (PATH) program.

Clinical practice guidelines specific to the medical care of frail older adults have yet to be widely disseminated. Because of the complex conditions associated with frailty, guidelines for frail older patients should be based on careful consideration of the characteristics of this population, balanced against the benefits and harms associated with treatment. In response to this need, the Diabetes Care Program of Nova Scotia (DCPNS) collaborated with the Palliative and Therapeutic Harmonization (PATH) program to develop and disseminate guidelines for the treatment of frail older adults with type 2 diabetes. The DCPNS/PATH guidelines are unique in that they recommend the following: 1. Maintain HbA1c at or above 8% rather than below a specific level, in keeping with the conclusion that lower HbA1c levels are associated with increased hypoglycemic events without accruing meaningful benefit for frail older adults with type 2 diabetes. The guideline supports a wide range of acceptable HbA1c targets so that treatment decisions can focus on whether to aim for HbA1c levels between 8% and 9% or within a higher range (ie, >9% and <12%) based on individual circumstances and symptoms. 2. Simplify treatment by administering basal insulin alone and avoiding administration of regular and rapid-acting insulin when feasible. This recommendation takes into account the variations in oral intake that are commonly associated with frailty. 3. Use neutral protamine Hagedorn (NPH) insulin instead of long-acting insulin analogues, such as insulin glargine (Lantus) or insulin detemir (Levemir), as insulin analogues do not appear to provide clinically meaningful benefit but are significantly more costly. 4. With acceptance of more liberalized blood glucose targets, there is no need for routine blood glucose testing when oral hypoglycemic medications or well-established doses of basal insulin (used alone) are not routinely changed as a result of blood glucose testing.Although these recommendations may appear radical, they are based on careful review of research findings.

Determinants of lifestyle behavior in type 2 diabetes: results of the 2011 cross-sectional survey on living with chronic diseases in Canada.

BACKGROUND: Lifestyle behavior modification is an essential component of self-management of type 2 diabetes. We evaluated the prevalence of engagement in lifestyle behaviors for management of the disease, as well as the impact of healthcare professional support on these behaviors. METHODS: Self-reported data were available from 2682 adult respondents, age 20 years or older, to the 2011 Survey on Living with Chronic Diseases in Canada's diabetes component. Associations with never engaging in and not sustaining self-management behaviors (of dietary change, weight control, exercise, and smoking cessation) were evaluated using binomial regression models. RESULTS: The prevalence of reported dietary change, weight control/loss, increased exercise and smoking cessation (among those who smoked since being diagnosed) were 89.7%, 72.1%, 69.5%, and 30.6%, respectively. Those who reported not receiving health professional advice in the previous 12 months were more likely to report never engaging in dietary change (RR = 2.7, 95% CI 1.8 - 4.2), exercise (RR = 1.7, 95% CI 1.3 - 2.1), or weight control/loss (RR = 2.2, 95% CI 1.3 - 3.6), but not smoking cessation (RR = 1.0; 95% CI: 0.7 - 1.5). Also, living with diabetes for more than six years was associated with not sustaining dietary change, weight loss and smoking cessation. CONCLUSION: Health professional advice for lifestyle behaviors for type 2 diabetes self-management may support individual actions. Patients living with the disease for more than 6 years may require additional support in sustaining recommended behaviors.

Hypertension and type 2 diabetes: what family physicians can do to improve control of blood pressure--an observational study.

BACKGROUND: The prevalence of type 2 diabetes is rising, and most of these patients also have hypertension, substantially increasing the risk of cardiovascular morbidity and mortality. The majority of these patients do not reach target blood pressure levels for a wide variety of reasons. When a literature review provided no clear focus for action when patients are not at target, we initiated a study to identify characteristics of patients and providers associated with achieving target BP levels in community-based practice. METHODS: We conducted a practice-based, cross-sectional observational and mailed survey study. The setting was the practices of 27 family physicians and nurse practitioners in 3 eastern provinces in Canada. The participants were all patients with type 2 diabetes who could understand English, were able to give consent, and would be available for follow-up for more than one year. Data were collected from each patient's medical record and from each patient and physician/nurse practitioner by mailed survey. Our main outcome measures were overall blood pressure at target (< 130/80), systolic blood pressure at target, and diastolic blood pressure at target. Analysis included initial descriptive statistics, logistic regression models, and multivariate regression using hierarchical nonlinear modeling (HNLM). RESULTS: Fifty-four percent were at target for both systolic and diastolic pressures. Sixty-two percent were at systolic target, and 79% were at diastolic target. Patients who reported eating food low in salt had higher odds of reaching target blood pressure. Similarly, patients reporting low adherence to their medication regimen had lower odds of reaching target blood pressure. CONCLUSIONS: When primary care health professionals are dealing with blood pressures above target in a patient with type 2 diabetes, they should pay particular attention to two factors. They should inquire about dietary salt intake, strongly emphasize the importance of reduction, and refer for detailed counseling if necessary. Similarly, they should inquire about adherence to the medication regimen, and employ a variety of patient-oriented strategies to improve adherence.

Hypertension control: results from the Diabetes Care Program of Nova Scotia registry and impact of changing clinical practice guidelines.

BACKGROUND: The objective of this study was to determine the rate of blood pressure control according to 4 sets of Canadian guidelines published over a decade in patients with diabetes mellitus attending Diabetes Centres in the province of Nova Scotia. METHODS: One hundred randomly selected charts from each of 13 Diabetes Centres audited between 1997 and 2001 were extracted from the Diabetes Care Program of Nova Scotia Registry. Multivariate logistic regression analyses examined the relationship between individual characteristics and self-reported antihypertensive use. Included were 1132 adults, mean age 63 years (48% male), with 9 years mean time since diagnosis of diabetes. RESULTS: According to the 1992 guidelines, 63% of the patients and according to the 2003 guidelines, 84% of patients were above target blood pressure or receiving antihypertensive medications. Forty-seven percent of patients are considered to be hypertensive and not on treatment according to 2003 guidelines. The results of the multivariate analyses showed that the only factors independently associated with anti-hypertensive use was oral anti-hyperglycemic use. CONCLUSION: Hypertension is an additional risk factor in those with diabetes mellitus for macrovascular and microvascular complications. The health and budgetary impacts of addressing the treatment gap need to be further explored.
