Children's Hospital Los Angeles E-protocol Insulin - Objective and Study Design __________________________________________________ Background: The focus of this study is a software decision-support tool (eProtocol-insulin) developed to guide caretakers in insulin administration. The eProtocol-insulin software will be housed in laptop computers placed at the bedside or in a location close to patients' rooms. Objectives of the study: We will implement the validated Phase-1 eProtocol-insulin with the 80-110 mg/dl target in both adult and pediatric Phase-2 (naive) sites.      a. We will calculate clinician compliance with eProtocol-insulin instructions.                i. We will quantify the reasons for non-compliance with protocol instructions.      b. Regarding the 80-110 mg/dl blood glucose target, we will calculate:               i. The proportion of measurements between 80-110 mg/dl for:                   a. All measurements                   b. Measurements after first reaching 80-110 mg/dl.               ii. The time required to first reach 80-110 mg/dl.      c. We will repeat the calculations for i.b above for glucose values falling within the              normal range (between 70 and 110 mg/dl).
