Summary
A new web system aids insulin self-titration and patient monitoring. Usability testing identified 81 issues, including four safety concerns, before implementation to ensure safe and effective use.
Area of Science:
- Digital Health
- Human-Computer Interaction
- Patient Safety
Background:
- Insulin self-titration requires patient and caregiver support.
- Web-based systems offer potential for improved diabetes self-management.
- Usability is critical for user adoption and patient safety in digital health tools.
Purpose of the Study:
- To evaluate the usability of a novel web-based system for insulin self-titration and patient monitoring.
- To identify potential usability flaws that could impact user experience and patient safety prior to clinical implementation.
Main Methods:
- Cognitive walkthrough sessions were conducted by two pairs of researchers.
- Systematic identification and documentation of usability problems were performed.
Main Results:
- A total of 81 unique usability problems were identified.
- Four usability issues were flagged as having a potential direct impact on patient safety.
- The evaluation process highlighted areas for system improvement.
Conclusions:
- Pre-implementation usability evaluations are essential for digital health tools.
- Addressing usability issues can prevent user attrition and mitigate risks to patient safety.
- Proactive identification of problems ensures a safer and more effective patient support system.

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...

01:27Insulin 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.
Short-acting insulins are divided into rapid-acting...
