Improving Blood Glucose Control With a Computerized Decision Support Tool: Phase 2

Study Overview
=================
Brief Summary
-----------------
The Purpose of this study is to: Introduce the refined, validated, and safe computerized bedside decision support tool for blood glucose management in critically ill adult and pediatric ICU patients that was studied in Phase 1 into a second group of naïve ICUs, none of which participated in eProtocol-insulin development, refinement or validation Monitor how often low blood sugar levels occur during use of the bedside tool. Determine how the computerized tool effects the workload of the ICU nurses.

Detailed Description
-----------------
In the current second phase of this project (Phase-2), we will introduce the refined, validated, and safe eProtocol-insulin into a second group of naïve ICUs, none of which participated in eProtocol-insulin development, refinement or validation. Our primary goal in this second phase is to determine the feasibility of exporting this tool to naïve ICU environments. In this second phase we will also compare the effects of the eProtocol-insulin and ordinary care approaches to glucose control on the bedside nurse's experience. This second phase will be a prospective cohort study. We will determine the feasibility of distributing eProtocol-insulin and will further validate eProtocol-insulin in >4 adult and >4 pediatric ICUs. If necessary we will modify eProtocol-insulin with an iterative refinement process, with Institutional Review Board (IRB) and independent Data and Safety Monitoring Board (DSMB) oversight. eProtocol-insulin will be considered refined if >90% of the instructions are accepted and if the percent of glucose values between 70 and 110 mg/dl (3.9-6.1 mMol/L) are equivalent to our Phase-1 refinement and validation experience of 46%%, and if the rate of glucose values < 40 mg/dl (2.2 mMol/l) is less than 0.5% of glucose measurements.

Official Title
-----------------
Clinical Process Improvement With A Bedside Computerized Insulin Therapy Protocol For Blood Glucose Control (eProtocol-insulin) in Adult And Pediatric Intensive Care Unit Patients-Second Phase (Phase-2): Distribution and Implementation of Validated eProtocol-insulin in Naïve ICUs

Conditions
-----------------
Critically Ill, Hyperglycemia

Intervention / Treatment
-----------------
* Procedure: glucose control with computer generated recommendations


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Pediatric ICU: Proposed indications by pediatric clinicians at participating ICUs for glucose control in their ICUs would include patients who require mechanical ventilation for greater than 24 hours and/or require a vasoactive infusion (e.g. dopamine >3 mg/kg/min, dobutamine, epinephrine, or vasopressin). Adult ICUs: Proposed indications by clinicians in participating ICUs for glucose control in participating adult ICUs include critically ill patients with an anticipated ICU length of stay of 3 or more days. Exclusion Criteria: Pregnancy (negative pregnancy test required for females of child-bearing age) Age less than one month Inborn errors of metabolism that the clinician suspects will affect glucose homeostasis Acute or chronic liver disease with any documented episode of blood or plasma glucose <60 mg/dl within the 24 hours prior to study entry Diabetic Ketoacidosis (critically ill patients with insulin dependent diabetes not in ketoacidosis will be eligible if attending physicians intend to use intravenous insulin as part of ordinary care) Severe chronic liver disease (Child-Pugh score >10)

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The primary outcome variable for feasibility during Phase-2 will be the acceptability of the eProtocol-insulin instructions (compliance of bedside clinicians with instructions). Proportion of glucose values < 40 mg/dl. |  | 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of glucose determinations between 70 and 110 mg/dl (3.9-6.1 mMol/L) (efficacy) |  | 1 year | 
| Time to reach the 80-110 mg/dl target |  | 1 year | 
| Nursing perception of workload in comparison to ordinary care (efficacy and feasibility) |  | 1 year | 
| Proportion of glucose values 41-60 mg/dl |  | 1 year |
