Using a typical data management system

You can use a data management system on just about any home blood glucose meter to plot your child's blood glucose and determine where changes need to be made. Figure 7-3 plots the results before changes were made in the treatment, and Figure 7-4 shows the results after those changes. You can see the difference very clearly. Here are the elements of each figure:

i The Trendgraph at the top of each page shows the individual blood glucose values. The horizontal or x-axis represents the days, and the vertical or y-axis represents the blood glucose values shown by a X. Underneath the Trendgraph, the program has figured out the MBG, the mean blood glucose, 159 mg/dl on the before page and 119 mg/dl on the after page. The program also shows the percentage of readings in three categories: less than 80 mg/dl (low), 80 to 180 mg/dl (normal), and over 180 mg/dl (high).

Comparing the two graphs, the percentage of normal readings in the after page is much greater (63.4 percent before, 77.4 percent after), whereas the percentage of high readings is substantially lower (31.7 percent before, 6.5 percent after). The thick black line averages out the glucose values for each day. You can see that it hovers around 150 mg/dl before and 110 mg/dl after treatment.

i Below the Trendgraph, the Standard Day puts all the blood glucoses from a specific range of time into the same area of the graph. Night is midnight to 5:30 a.m., before breakfast is 5:30 to 8:30 a.m., and so forth. It's easy to see by the position of the large X (the average for that time range) that the blood glucose is around 150 mg/dl throughout the day before treatment and is usually at 100 mg/dl after treatment.

i The Pie Chart graphically shows that the control is much better after treatment than it before, although there are more low readings (less than 80 mg/dl) after treatment.

You can also use the data management software to show every permutation of the blood glucose values. For example, it's easy to produce a graph that shows the average blood glucose for each day of the week. From such a graph, your child's doctor can see what time of day requires more or less insulin, more or less food, and more or less exercise to improve control.
