The modern management of diabetes relies heavily on self-monitoring of blood glucose (SMBG), and therefore SMBG records are an important source of clinical data for management decision making. The development of a memory Glucometer has provided the opportunity to verify the validity of glucose records thus generated and observe the effects of different educational approaches on compliance with SMBG. Thirty-four patients without previous experience of SMBG were randomized into one of the following experimental groups differing in the model of diabetes care: mutual decision making, didactic, and authoritarian. Patients, unaware of the memory capacity of the glucose meter, were required to perform four glucose measurements per day over a 14-day observation period. Patient-generated blood glucose records were then compared with objective records stored in the glucose-meter memory. Patients with gestational diabetes mellitus recorded a lower proportion of correct results (63 vs. 79%, P = .049) and exhibited a tendency to invent results with lower blood glucose levels (5.3 vs. 7.5 mM, P < .0001) than the results omitted compared with patients with non-insulin-dependent diabetes mellitus. Predictors of greater validity of records were perceived intelligence of the subject (χ2 = 4.56, P < .02) and private health-insurance status (χ2 = 4.52, P < .04), whereas the experimental group assignment was not significant. These findings reflect potential motivational and sociodemographic limitations in the validity of SMBG recordings within the management and education of patients with gestational and nongestational diabetes.
