9 9 Most of these usability improvements are beyond the current standard—not required under ISO 15197Most of these usability improvements are beyond the current standard—not required under ISO Beyond usability improvements, other significant improvements include less susceptibility to interferents (e.g. hematocrit, oxygen)Beyond usability improvements, other significant improvements include less susceptibility to interferents (e.g. hematocrit, oxygen) All of these advances are part of industry efforts to support technology innovations that improve health care and lead to better outcomes.All of these advances are part of industry efforts to support technology innovations that improve health care and lead to better outcomes. Beyond Usability Improvements

10 10 Clinical studies show home BGMs meeting the current accuracy standard for self-testing (ISO 15197) were associated with improved glycemic control and positive clinical outcomes (e.g. DCCT)Clinical studies show home BGMs meeting the current accuracy standard for self-testing (ISO 15197) were associated with improved glycemic control and positive clinical outcomes (e.g. DCCT) Current standard produces clinically acceptable results—According to Consensus Error Grid analysis (EGA), 95% of results in range A (no effect on clinical action) and remainder in range B (altered clinical action with little/no effect on clinical outcome)Current standard produces clinically acceptable results—According to Consensus Error Grid analysis (EGA), 95% of results in range A (no effect on clinical action) and remainder in range B (altered clinical action with little/no effect on clinical outcome) Strongly suggest consideration of EGA as important tool for objective assessment of BGMs for self-testingStrongly suggest consideration of EGA as important tool for objective assessment of BGMs for self-testing Impact of criteria changes on current meters should be considered (e.g. increased test time, usability, cost)Impact of criteria changes on current meters should be considered (e.g. increased test time, usability, cost) BGMs and Role in Diabetes Care

11 11 The current accuracy criteria in ISO standard is specific to self-monitoring/home use—not professional useThe current accuracy criteria in ISO standard is specific to self-monitoring/home use—not professional use Industry fully support efforts to develop increased accuracy requirements for BGMs used in hospitals and long-term facilities [CLSI POCT(12): Point-of-Care Blood Glucose Testing in Acute and Chronic Care Facilities]Industry fully support efforts to develop increased accuracy requirements for BGMs used in hospitals and long-term facilities [CLSI POCT(12): Point-of-Care Blood Glucose Testing in Acute and Chronic Care Facilities] –Both FDA and industry are engaged in this effort. –The potential consequences of an inaccurate glucose result in these particular settings (e.g. immediate treatment decisions, increased susceptibility of hospitalized patient) merit guideline development for meters used in those settings. –Standard for home use was not intended for tight glycemic control (TGC) in hospital—we fully support efforts to address in POCT(12) Guidelines for BGMs for Hospital Use

12 12 Recent advances made by industry contributing to overall device performanceRecent advances made by industry contributing to overall device performance As part of that commitment along with other revisions to the home use standard, industry strongly supportsAs part of that commitment along with other revisions to the home use standard, industry strongly supports – revising accuracy standard for >95% of individual glucose results to: +15 mg/dL from the reference glucose values and +15% (ISO 15197, Section 7) Also consensus recognition that the standard for hospitals is CLSI POCT(12), not ISO 15197Also consensus recognition that the standard for hospitals is CLSI POCT(12), not ISO Also discussion of interfering factors and how to best deal with in ISO 15197Also discussion of interfering factors and how to best deal with in ISO Industry supports all these effortsIndustry supports all these efforts Support for Evolution of BGMs for Home Use
