A randomized, controlled comparison of instruction by a diabetes educator versus self-instruction in self-monitoring of blood glucose
WK Ward, LB Haas and JC Beard
It is not clear whether diabetic patients can learn accurate
self-monitoring of blood glucose (SMBG) by use of written package
instructions. In addition, it is unclear whether the improvement in
accuracy of monitoring that results from professional training is due to
the professional intervention or to a personal practice effect. For these
reasons, improvement in accuracy of SMBG (using Chemstrip bG, Biodynamics
Division, Boehringer-Mannheim, Indianapolis, Indiana) after a 30-min
session of professional instruction in one group of diabetic patients was
compared with improvement after 30 min of practice and study of package
instructions in another group. After initial reading of package
instructions in both groups, and after the practice session in the control
group, mean percent error was 22-37%. In contrast, mean percent error
declined to 9% after a professional training session. We conclude that
learning SMBG solely by reading package instructions leads to unacceptable
inaccuracy. However, by use of short, intensive instruction sessions, a
diabetes educator can reduce such errors and teach highly accurate
monitoring to most diabetic patients.
