Summary
Intensive insulin therapy protocols for critically ill patients were compared. A new nomogram improved insulin dose calculation accuracy and practicality for nurses compared to traditional chart protocols.
Area of Science:
- Critical care medicine
- Nursing practice
- Pharmacology
Background:
- Intensive insulin therapy is crucial for reducing morbidity and mortality in critically ill patients.
- Nurses commonly use chart-based protocols for hourly titration of insulin infusions.
- Existing protocols' accuracy, practicality, and ease of use by nurses have not been thoroughly evaluated.
Purpose of the Study:
- To evaluate a newly developed nomogram for clinical practicality, ease of understanding, and efficiency compared to existing chart protocols.
- To assess critical care nurses' preferences and provide feedback on insulin dosing tools.
Main Methods:
- 153 critical care nurses calculated insulin doses using hypothetical patient data with both chart and nomogram protocols.
- Time to calculation, accuracy, nurse preference, and qualitative feedback were systematically examined across three study phases.
Main Results:
- No significant difference in calculation time was found between the nomogram and chart methods.
- Nurse experience did not significantly impact calculation time or accuracy.
- Accuracy of insulin dose calculations improved with nomogram revisions.
- Nurses showed no preference between tools but provided valuable feedback for nomogram refinement.
Conclusions:
- The developed nomogram is practical, user-friendly, and enhances the accuracy of insulin dosage calculations for critical care nurses.
- The nomogram is a valuable bedside tool for improving patient care through precise insulin titration.

01:23Dosage Regimen Designs: Nomograms and Tabulations
Nomograms and tabulations are vital tools used by clinicians to design accurate and individualized dosage regimens. These instruments provide a straightforward method for adjusting dosages based on individual patient characteristics, including age, weight, and physiological condition. The foundation of a drug's nomogram is population pharmacokinetic data collected and analyzed using specific models. This data simplifies complex equations, presenting them diagrammatically or tabularly for easy...
01:25Insulin: Biosynthesis, Chemistry, and Preparation
The endoplasmic reticulum (ER) of pancreatic β-cells synthesizes preproinsulin, which consists of a signal peptide, A and B chains, and a C-peptide. Preproinsulin is then cleaved and folded into proinsulin, which translocates to the Golgi apparatus for sorting and packaging into secretory granules. In these granules, enzymatic clipping generates insulin and C-peptide.

01:27Insulin Formulations: Types and Delivery
Insulin preparations are categorized by their duration of action into short-acting and long-acting types. Two strategies are used to modify insulin's absorption and pharmacokinetic profile: slowing the absorption post-subcutaneous injection, or altering human insulin's amino acid sequence or protein structure. These changes retain the insulin's ability to bind to the insulin receptor, but alter its behavior in solution or after injection.

01:16Insulin: Dosing Regimen and Adverse Effects
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

01:12Type I Diabetes I: Introduction
Type 1 diabetes mellitus is a chronic metabolic disorder characterized by an absolute deficiency of insulin resulting from the autoimmune destruction of pancreatic β-cells. Although it can occur at any age, it is most commonly diagnosed in childhood, adolescence, or early adulthood. The loss of insulin production impairs cellular glucose uptake, resulting in persistent hyperglycemia and necessitating lifelong insulin therapy.Autoimmune Destruction of β-CellsThe hallmark of type 1 diabetes is an...
01:26Type I Diabetes II: Pathophysiology
Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...
