Behavioral skills in self-monitoring of blood glucose: relationship to accuracy
RR Wing, R Koeske, A New, D Lamparski and D Becker
Sixty-two children and adolescents with IDDM were observed while performing
self-monitoring of blood glucose (SMBG) to determine which of the behaviors
involved in SMBG were most likely to be performed incorrectly and which
errors had the greatest effect on the accuracy of SMBG readings. Behaviors
related to cleanliness and timing were performed most poorly; only 60% of
the subjects correctly timed the first minute, and 30-33% correctly timed
the second interval. The duration of SMBG and frequency of monitoring were
not related to proper performance of the behaviors involved in SMBG.
Accuracy of SMBG was assessed by comparing subjects' readings to laboratory
values obtained immediately afterward. The behavior that had the greatest
effect on the accuracy of SMBG readings was that concerning whether the
blood was adequately wiped from the Chemstrip bG. This behavior should
receive more emphasis in SMBG training programs. The systematic observation
procedure used in this study may help to identify errors made by patients
while performing SMBG and may serve as the basis for training programs to
improve SMBG accuracy.
