Insights
Continuous subcutaneous insulin infusion (CSII) may offer benefits over multiple daily injections (MDI) for children with diabetes, but cost-effectiveness requires better well-being assessment. More research is needed to compare these diabetes management methods.
Area of Science:
- Pediatric Endocrinology
- Health Economics
- Diabetes Management
Background:
- Continuous subcutaneous insulin infusion (CSII) and multiple daily injections (MDI) are primary methods for pediatric diabetes management.
- Assessing the cost-effectiveness of CSII versus MDI in children requires a comprehensive understanding of clinical efficacy and patient-reported outcomes.
Purpose of the Study:
- To review the cost-effectiveness of CSII compared to MDI in children with diabetes.
- To evaluate clinical benefits, including hemoglobin A1c (HbA1c) levels, and perceived benefits by patients and parents.
Main Methods:
- Review of existing literature on cost comparisons and clinical efficacy of CSII versus MDI in pediatric populations.
- Analysis of direct extra costs associated with CSII, including pump supplies and maintenance.
- Comparison of outcomes from randomized and non-randomized studies.
Main Results:
- Direct extra costs for CSII can be approximately double those of MDI (5000-6000 EUR vs. 3000 EUR per patient year).
- Randomized trials show limited significant clinical differences between CSII and MDI in children, while non-randomized studies suggest CSII may be favored.
- Quality of life parameters are inadequately assessed in current comparisons.
Conclusions:
- There is a significant need for improved parameters to assess the well-being of children with diabetes using CSII or MDI.
- Accurate cost-effectiveness analysis of CSII versus MDI in pediatric populations is currently limited by a lack of comprehensive outcome measures.
Abstract:
Cost-effectiveness of continuous subcutaneous insulin infusion (CSII) in children is reviewed in the context of possible improvement of percentage of hemoglobin A1c (HbA1c) and of other clinical benefits over multiple daily injections (MDI). Cost-effectiveness depends on clinical efficacy but reported clinical efficacy parameters may overlook definite benefits perceived by children and parents using CSII. There are few detailed reports on cost comparisons between CSII and MDI in adults, even less in children or adolescents. Review of direct extra costs for CSII over conventional treatment, including MDI, suggest that these may double, 5000-6000 EUR vs. 3000 EUR per patient year. An example is given of how to calculate direct cost differences, showing local differences. Randomized comparisons between CSII and MDI in childhood and adolescence show few marked clinical effects, but non-randomized comparisons favor CSII. Quality of life parameters fall short in any such comparison in children and adolescents alike. The reasons for the apparent discrepancy between non-randomized childhood studies and the randomized prospective ones are given. There is a dire need for better parameters to assess the well-being of diabetic children treated by CSII or MDI. Only then is it warranted to estimate the cost-effectiveness of CSII vs. MDI in childhood and adolescence.
