Analysis was performed using statistical process control.
Results IIT guideline: the new guideline emphasized fast correction of high BGLs, acceptance of low BGLs and frequent BGL measurements (up to one/hour). Blood glucose control: BGLs of approximately 8,000 patients were collected and analyzed. The case mix was similar in guideline and
control ICUs, and did not change over time. No change in overall blood glucose control or incidence of SH was observed in the control ICUs during the study duration. In the guideline ICUs, the median number of daily blood glucose measurements increased from 4 (3 to 7) per patient to 9 (5
to 12) per patient (P
