Summary
Diabetic patients often waste significant amounts of injected insulin due to improper technique and equipment. Optimizing insulin delivery can improve treatment effectiveness and reduce unnecessary waste.
Area of Science:
- Endocrinology
- Metabolic Diseases
- Pharmacology
Background:
- Insulin therapy is crucial for managing diabetes.
- Quantifying insulin wastage is important for optimizing patient care and resource allocation.
Purpose of the Study:
- To determine the extent of insulin wastage in diabetic patients.
- To identify factors contributing to insulin wastage during self-administration.
Main Methods:
- Analysis of insulin prescriptions for 162 patients over a year.
- Direct observation of insulin drawing technique in 101 patients.
Main Results:
- Mean daily insulin consumption was 58.6 U, with 41.7 U injected, indicating significant wastage.
- Factors contributing to wastage included air expulsion, non-low-dead-space syringes, and inappropriate syringe size.
- Visual impairment was associated with increased insulin loss.
Conclusions:
- Substantial insulin wastage occurs, influenced by technique and equipment.
- Patient education on proper insulin drawing and syringe selection is essential.
- Addressing wastage can improve therapeutic outcomes and cost-effectiveness.
