Unfortunately the majority of studies of whether SMBG is useful involve a question “Is SMBG useful to cliniciians?” And the answer is surprisingly “NO.” And we say “DUH?” Who in their right mind would even ask such a stupid question.
The real question is “Does SMBG help a patient make better actionable decisions?” I posted back in 2015 a study by a researcher who looked at this question
The answer is obviously yes and leads to a second question. Why aren’t patients being taught to eat to their meter?
