The Glucometrics Report
Here's a sample glucometrics report. Right click on the link to save to your desktop.
Administrative Data
A metrics report begins by printing the name of its data file and the date and time when the report was computed. Next it displays the coded institution name, ward name and ward type as well as the date of the first and last record in the file.
Glucometrics
Glucometrics are then shown graphically and in tabular form.
Graphics
These graphics show the distribution of individual glucose samples, the patient-stay mean glucoses, and the patient-day mean glucoses.
Here's an enlarged version of the histogram.
The bars and dot show data spread, the 5th, 25th, 50th, 75th, and 95th percentiles. The grey bar on the x–axis shows the range of goal glucoses.
Stringent glucose control will yield narrow histograms with more glucoses in the target range.
In comparison, lax control will show broader histograms.
Note that the percentile bars also narrow and widen according to control; narrower bars depict data with less variation.
Table
Following the graphics, a table shows the metrics computed using the three different units of analysis: patient-sample (individual glucoses), patient–stay (mean glucoses), patient–day (mean-glucoses). For each unit of analysis, these statistics are reported:
- Number
- Mean and median
- 5th and 95th percentiles
- spread (difference between 5th and 95th percentiles)
- number and percent of data
- within target range of 70-149
- within hypoglycemic range <70
- within hyperglycemic range > 299
Ancillary Statistics
Patients with only one glucose measurement
We exclude these patients from metrics computation, but report their number as well as the distribution of glucose values. If a large proportion of these single-valued patients have hyperglycemic glucoses, one can ask why they received no follow up measurements.
Frequency and duration of measurement
Using histograms and tables, this section shows the frequency of monitoring during the day, the number of hours between measurements, and the total number of days of monitoring.
Errors
If there were non-numeric data in the data file (such as, "<60") or if there were negative valued glucoses (usually -1 indicating a meter error), we report the number here.
