OBJECTIVE: To determine the effect on glycemic control in intensively
treated type 1 diabetic patients using a blood glucose meter with storage
capability and computer-assisted analyses. RESEARCH DESIGN AND METHODS:
Glycemic control was assessed in 22 intensively treated adults with type 1
diabetes for 12 months while using a meter without memory, followed by 12
months while using a meter with memory. Log books were used to assist
patients in managing aspects of the diabetes treatment plan during the
first 12-month period, and computer-assisted analyses were used when the
meter with memory was used. GHb levels were measured monthly throughout the
24 months of observation. RESULTS: The mean GHb level averaged across all
patients during the period of memory meter use (6.4%) was significantly
lower than that during the period of meter use without memory (6.9%)
(P=0.0004). The change in GHb levels from each period-specific baseline
level occurred at significantly different slopes (P=0.046) when adjusted
for baseline GHb level. In addition, the downward trend in GHb level was
greater in those patients who increased the frequency of testing the most
(r=-0.54, P=0.01). CONCLUSIONS: Use of a meter with memory in conjunction
with computer-generated analyses of stored blood glucose test results can
lead to improved glycemic control when used by a group of intensively
treated adult diabetic patients. Improvement in glycemic control was
related to frequency of blood glucose testing.
