Summary of evidence evaluation

Evidence of the effectiveness of self-monitoring, relative to no self-monitoring or other alternatives, is scarce and of questionable validity (one case series) and applicability (association between monitoring frequency and outcomes). Available evidence, while of very low certainty, suggests that higher frequencies of self-monitoring might improve HbA1c control. Despite this lack of good quality evidence, self-monitoring appears to be widely recommended as part of routine care in diabetic patients using insulin therapy.

Summary of SAGE IVD deliberations

This edit would add a new test purpose for self-monitoring diabetes at home to the already existing glucose meter non-laboratory-based assay in the EDL. SAGE IVD considered the submission to be generally good and aligned with WHO guidelines, in particular for diabetes, for primary health care interventions and for self-health care. One expert observed that promoting self- monitoring of glucose at home with test strips will result in better control of diabetes and will also help to make support for the technology a priority at the government level. In this regard, including the test in the EDL constitutes a step towards reducing inequities. It was also noted that this application was the only one to receive considerable attention during the call for public comments phase, including two comments from people living with diabetes who provided evidence. SAGE IVD also commented on the role of the EDL in highlighting what is available and useful in the field even when it is not yet in the guidelines, especially in settings where access to clinical laboratories is limited. One point of confusion concerned a footnote included in the proposed edit to the test purpose provided by the applicant appearing to say that the test was for self-monitoring type 2 diabetes when indicated or recommended but not for type 1. SAGE IVD suggested removing the footnote to avoid misunderstanding, as the test is clearly meant for self-monitoring of both type 1 and type 2 diabetes. Literature cited in the discussion: Diabetes.

SAGE IVD recommendation

SAGE IVD recommended including the proposed edits to the test purpose of the glucose IVD test, for the glucose meter assay format in EDL 4 ■ as a disease-specific IVD for use in community settings and health facilities without laboratories (EDL 4, Section I.b); ■ using a glucose meter format; ■ using capillary whole blood as specimen type; ■ to self-monitor type 1 and type 2 diabetes mellitus at home.

Details of submission from 2022

Background

For young people living with type 1 diabetes, daily insulin replacement is required for survival. Self-monitoring of blood glucose (SMBG) is universally recognized as the most important part of insulin therapy. Regular, daily SMBG outside of the health facility ensures that people using insulin are able to use it safely and efficaciously and helps them maintain target-range daily glucose levels, thus reducing glycated haemoglobin (HbA1c) levels and early and devastating complications, including blindness and renal failure. Life for a Child has done extensive research, with international colleagues, documenting the provision of blood glucose meters and test strips for SMBG purposes (1, 2, 3, 4) and has consistently found that access to this crucial component of care for people living with type 1 diabetes is extremely deficient in LMICs. Low rates of access to SMBG are largely due to lack of health system provision. The consequences of this include poorly controlled diabetes, high prevalence of complications and catastrophic financial impacts on patients and their families. In a 2018 paper (2) published in Lancet Diabetes & Endocrinology, Life for a Child first expressed support on seeing that glucose testing was included as a diagnostic for diabetes in the first WHO model list of essential in vitro diagnostics but argued that this ought to include SMBG supplies for long-term use in future versions. FIND together with partners has published a market report on diabetes self-monitoring devices in LMICs (5) that analyses the blood glucose test strip market and access barriers to testing supplies. Further to this work, FIND has engaged with blood glucose test strip manufacturers to improve the affordability of these products for LMICs (6), resulting in some of the lowest access pricing available to LMIC buyers today (7). The addition of “Diabetes mellitus” to the disease-specific section of the third EDL and the associated listing of blood glucose meters as IVDs recommended for use in community settings and health facilities without laboratories was welcome to raise the priority of these IVDs for availability at low levels of care, where blood glucose meters are frequently absent (8). This application is submitted with the goal of extending the list of test purposes to include specific mention of self-monitoring for people living with diabetes. The applicants believe this would further strengthen the important role these IVDs play in diabetes management and heighten awareness among stakeholders who consult the EDL to define diagnostics needs in their country. While the EDL includes terminology such as “home-based” and “self-testing”, the applicants deem the extension of the test purpose to include “self-monitoring” as critical to ensure the neglected use case of blood glucose meters and test strips for self-monitoring gets the attention that people living with diabetes need at the country level.

Levels of type 1 diabetes care in children and adolescents for countries at varying resource levels. Pediatr Diabetes. 2019;20(1):93–8. ■ “All people with type 1 diabetes (T1D) deserve quality care. In countries that can afford it, comprehensive, guidelines-based care should be provided through the respective government health service. Currently, however, many less-resourced countries are only providing what we have defined as ‘minimal care,’ which has a high morbidity and mortality. We therefore encourage and recommend that less-resourced countries support ‘intermediate care,’ an approach that is substantially less expensive than comprehensive care but can still achieve markedly improved outcomes. The key components of intermediate care are human insulin in a basal bolus regimen, SMBG, point-of-care HbA1c testing, diabetes education, basic complications screening, and access to a doctor and nurse experienced in T1D care in young people.” ■ “Access to SMBG is a profound issue for improving T1D care in less-resourced settings, and national and international advocacy and innovative approaches are needed to address this issue.” Silver B, Ramaiya K, Andrew SB, Fredrick O, Bajaj S, Kalra S.

Diabet Med 2013;30:1255–62. ■ “HbA1c levels were similarly associated with SMBG frequency, although with no additional benefit beyond four tests per day.” Klatman EL, Jenkins AJ, Ahmedani MY, Ogle GD. Blood glucose meters and test strips: global market and challenges to access in low-resource settings. Lancet Diabetes Endocrinol. 2019;7(2):150–60. ■ “Diabetes is a unique medical condition with respect to the frequency of home measurements required.” ■ “Hypoglycaemia and hyperglycaemia occur acutely and frequently in people with diabetes, particularly in those who are treated with insulin. Long-term glycaemia is also a major determinant of chronic complications. Therefore, home monitoring of blood glucose with meters and test strips (self-monitoring of blood glucose [SMBG]) is widely used.” ■ “Home glucose monitoring began in the 1940–50s with urine testing, first using Benedict’s solution heated over a Bunsen burner, then effervescent tablets, and then urine test strips. SMBG was first used at home by Richard Bernstein in 1969. Since then, reflectance meters have been replaced by biosensor meters, with subsequent improvements in speed, miniaturisation, accuracy, and connectivity.” ■ The majority of blood glucose test strips used in LMICs today are utilized in health care facilities, and government procurement largely focuses on glucose testing needs in facilities. ■ The cost of test strips for people living with diabetes in LMICs is often prohibitive. This often limits SMBG to the absolute minimum for this group of people, sometimes leading them to forgo usage altogether, leading to dangerous extremes of glycaemia, highly impaired quality of life, and increased risk of developing serious and preventable metabolic complications. Klatman EL, McKee M, Ogle GD. Documenting and visualising progress towards universal health coverage of insulin and blood glucose test strips for people with diabetes. Diabetes Res Clin Pract. 2019;157:107859. ■ Provision of test strips through the health system is, for many people with diabetes, the only option to perform critically important SMBG, yet the large majority of LMIC health care systems do not provide test strips for self-monitoring. ■ In LMICs, provision of test strips is rarely covered within public health system benefit packages. ■ This study looking at provision of test strips found this number to be 14% of countries surveyed (n = 37). This is still the case in health insurance schemes, where a small percentage of the population can afford enrolment. This leaves people living with insulin-treated diabetes with no choice but to purchase test strips for SMBG out of pocket at private retail pharmacies (at a cost that can range from US$ 0.25 to US$ 1.65 (median US$ 0.49, mean US$ 0.56) for one test strip). ■ Given this lack of provision and high out-of-pocket costs for SMBG supplies, global commitments made towards Goal 3 of the United Nations’ Sustainable Development Goals, which calls on governments to ensure healthy lives and promote well-being for all at all ages, are leaving those with insulin-treated diabetes behind.

Diabet Med. 2016;33(6):820–6. ■ “For people living with diabetes in LMICs, even two test strips per day for SMBG over the course of a year often outweigh the annual cost of human insulin. The cost of two strips per day for one year as a percentage of per capita gross national income (GNI) ranged from 4% in Saint Lucia to 129% in Burkina Faso. The mean cost of two strips per day was 41% of the per capita GNI, and the median cost was 24%.” Pastakia SD, Cheng SY, Kirui NK, Kamano JH.
