Introduction

An earlier article described the role of the Nova Scotia Department of Health and Wellness and the work of the Diabetes Care Program of Nova Scotia (DCPNS) and its partners in approaching the controversial topic of self-monitoring of blood glucose (SMBG) in persons with non-insulin-using type 2 diabetes mellitus.

The question of whether all people with diabetes should self-monitor their blood glucose has received increasing attention in recent years. Individuals and/or the health care system struggle with costs related to testing, the limited evidence in support of testing for some populations and the utility of SMBG test results in helping individuals manage their disease. In January 2010, the DCPNS invited a multidisciplinary group of diabetes health care professionals to discuss recommendations regarding SMBG for non-insulin-treated type 2 diabetes, specifically its use, frequency and application in Nova Scotia. The proceedings of that workshop were presented in an earlier article.^{*), and demonstrate the value and the partnerships necessary to support change and promote consistency in approach across provider groups and practice settings.}

Post-workshop feedback

Following the January 2010 SMBG Workshop, participants responded to a series of consensus questions. This activity highlighted the power of evidence and thoughtful dialogue in coming to consensus on broad issues and the much more difficult task of reaching agreement on standardized approaches (specifics) due to individual patient and provider differences. The refinement of the decision tool (considerations, examples for testing) and the examples of supporting cases (ranging from simple to more complex) is as a result of this feedback (see Table 1).

Table 1. Responses to consensus questions from the Diabetes Care Program of Nova Scotia (DCPNS) Self-monitoring Blood Glucose (SMBG) Workshop

A “Needs and Wants” exercise was also used to ask participants, “What do you need to help make the changes as discussed [in the SMBG Workshop] a reality in your practice setting?” The participants were to consider this question in the context of each of three categories: individuals with diabetes, health care providers, and other organizations and agencies. These responses were used to support and plan a Nova Scotia–centred approach to SMBG that included partnerships, interdisciplinary sessions, newsletter articles, presentations to key stakeholder groups, the development of educational videos to support self-paced provider learning and patient handouts (see Table 2).

Non-Insulin Using Type 2 Diabetes: Decision Tool for Self-Monitoring of Blood Glucose

After many iterations and valued feedback from working group members and many others, the DCPNS finalized the one-page decision tool. The intent of the Non-Insulin Using Type 2 Diabetes: Decision Tool for Self-Monitoring of Blood Glucose is to address the need for a more consistent approach to the prescribing and practice of SMBG among and between different health care provider groups (physicians, pharmacists, diabetes educators and others). This colour-coded tool guides and focuses group discussion and individual decisions on issues of greatest concern when considering SMBG (Appendix A). Four key areas of consideration include:

• safety (e.g. risk of hyper- or hypoglycemia);
• appropriate and timely action by health care providers based on results of SMBG;
• individual’s knowledge, skills and willingness to test and record as well as ability to interpret and act on SMBG results; and
• self-management education.

The decision tool reinforces critical concepts, prompts yes/no responses to key questions, ensures consideration is given to additional issues that may impact the decision to self-monitor (including age, frailty, cognition and finances), provides examples of high- and low-intensity testing, and reinforces the need for time-limited testing in those who do test.

Mindful of the need for information and education through a variety of media, two short educational videos support the dissemination and uptake of the decision tool. Video 1 (SMBG Decision Tool for Health Care Providers) provides the rationale for the decision tool in light of the evidence and local considerations. Key opinion leaders provide their insights on SMBG in the non-insulin-using type 2 diabetes mellitus population, the rationale for the change in practice, the opportunities that this change creates for both patients and providers, and the value of the decision tool to reduce subjectivity and promote a more thoughtful approach to SMBG. Video 2 (Use of the SMBG Decision Tool and Case Studies) introduces the tool and illustrates how to use it. The video highlights the features of the tool, works through a sample case, summarizes principles and caveats to guide future application, and presents three additional case studies (from those newly diagnosed to those with long-standing diabetes) for providers to work through on their own.†

Although the official launch was to be in September 2010, the tool (without the videos) was first introduced to physicians, pharmacists and diabetes educators in May 2010 through academic detailing sessions conducted by the Office of Continuing Medical Education at Dalhousie University. The tool and the videos became the focus of inter-professional workshops held across Nova Scotia as of February 2011. These community-based sessions continue to be offered free of charge to physicians, diabetes educators and community pharmacists as well as interested inpatient, ambulatory care and community health care professionals. Supported by a local clinical expert, representatives from Dalhousie University’s Departments of Continuing Medical and Pharmacy Education, Capital Health’s Drug Evaluation Unit and the DCPNS lead the sessions. Each 90-minute session includes role-playing, overview of the evidence (with a focus on the local context), use of the SMBG Video 2 to introduce the decision tool and its various features followed by case-based, small group work led by the clinical expert.

Next steps

Opportunities to promote the tool and the need for consistency in approaches to SMBG continue to present themselves in the form of abstract submissions, conference presentations, speaking engagements, and sharing across provinces and agencies that have an interest in this topic. An evaluation plan is currently under development; it will include monitoring prescribing practices though the Nova Scotia Department of Health and Wellness Pharmacare Program and a review of diabetes educator practices related to use of the tool and approach to counselling.

Currently, DCPNS is leading the development of a parallel decision tool aimed at individuals with diabetes. This tool will explain why the recommended SMBG practices have changed and will include a simple self-test to assist individuals in determining if they need SMBG. For those needing to test, simple guidelines will explain when and how often to do so. This continued work will benefit from the insight of many partners who have provided support, encouragement and perspective. SMBG is not just a diabetes educator issue; it affects all providers across multiple settings who interact with people who have diabetes as well as individuals living with diabetes and their family members. A measured approach to SMBG will benefit individuals with diabetes: less testing means happier fingers and more effective use of personal health care dollars without compromising care or health outcomes. The health system will also benefit from more appropriate use of SMBG by reducing the burden of unnecessary and wasteful testing.

NON-INSULIN USING TYPE 2 DIABETES
Decision Tool for Self-Monitoring of Blood Glucose (SMBG)

Routine, ongoing testing is not necessary in most non-insulin managed type 2 diabetes. This decision tool will help to identify exceptions.

Instructions: Considering the individual, indicate with a Yes or No if the specific issue/consideration has an impact on the need for SMBG. The “prompting” considerations in italics should help in formulating your response.

• "Yes" in either of the pink areas is an indication for SMBG.
• "Yes" in all of the green areas, along with a Yes in the pink area, are required conditions before SMBG is recommended.
• "Yes" in the white area, in conjunction with Yes in all the green areas, may indicate the need for “low intensity” SMBG.

Low Intensity Testing

• Used to ↑ individual’s and/or provider’s understanding of effects of treatment.
• May assist clinicians in guiding therapeutic adjustments, providing more timely feedback regarding potential medication changes, and to identify postprandial hyperglycemia, if in question.²

Examples for use at diagnosis and ongoing follow-up (times can vary for 1 to 3 wks, depending on the purpose [prior to office visit, new dx]):

• 3 tests/day for 2 days/wk–one weekday and one weekend day (fasting and ac/pc at the largest meal [often supper]) for 2-3 wks.
• 2 tests/day–varying times (ac breakfast/supper; ac lunch/bedtime; etc.) for 1 wk.
• 1 test/day at staggered times (ac breakfast, lunch, supper, or bedtime) for 1-2 wks (prior to office visit).
• 1 test/wk between office visits.

High Intensity Testing

• Used for “pattern analysis” to create BG profiles that can identify daily BG patterns that lead to action based on results.
  Should be used only for a specific time and for a specific purpose; e.g., change in treatment (adding insulin or changing time of insulin), acute illness (flu, GI upset, etc.) resulting in symptoms or added risk, etc.²

Examples:

• Generally 5-7 tests/day for 1-3 days.
• Staggered testing, 2 x/day (ac and pc testing for alternating meals) x 1 wk, or over a 2-3 wk period.² Duration of testing depends on medication and degree of hyperglycemia (what change is expected over what period of time).
• Results should be reviewed by phone or during an office visit immediately after the testing period.

NOTE: Gestational diabetes or women with type 2 diabetes planning for pregnancy/or in the early stages of pregnancy will be required to test more routinely for extended periods of time.
