Self-monitoring of blood glucose for individuals with type 2 diabetes not using insulin: Leaving no cornerstone unturned

Self-monitoring of blood glucose in noninsulin-using type 2 diabetic patients: it is time to face the evidence

Given the importance of glycemic control in the development of diabetes complications, the plethora of tools now available to monitor the day-to-day trends in glycemia is remarkable. In this regard, self-monitoring of blood glucose (SMBG) has been considered a key component of patient management. Arguably, there remains almost universal agreement that SMBG should be available to all diabetic patients regardless of current treatment strategy. However, recently there have been reports that have challenged the current paradigm that all patients should use SMBG and concluded that SMBG for type 2 diabetic patients not on insulin may not be beneficial on glycemic control and must be weighed against the expense and inconvenience. In this two-part point-counterpoint narrative, Malanda et al. and Polonsky and Fisher take opposing views on the utility of SMBG to be valuable for individuals with type 2 diabetes not using insulin. In the narrative below, Malanda et al. suggest that the evidence for potentially beneficial SMBG-induced effects on glycemic control, hypoglycemic periods, and potential harms in type 2 diabetic patients who are not treated with insulin does not justify the use of SMBG. Moreover, the use of SMBG is associated with huge costs, which should be better redirected to effective strategies to improve health for this category of patients. -William T.
