Condition(s) studied

Diabetes Mellitus, Type 1

Investigational drug(s) / intervention(s)

Routine care data collection

Routine care data collection: Data collection from patients receiving standard care under a cooperation protocol for prandial insulin dose adjustment, with data collected from patients' medical records and glucose monitoring platforms without modifying patient management

Study summary

This retrospective multicenter cohort study aims to evaluate the effectiveness of an interprofessional cooperative protocol allowing dietitians to adjust prandial insulin-to-carbohydrate ratios in adults living with type 1 diabetes receiving functional insulin therapy. Glycemic outcomes will be assessed using continuous glucose monitoring data collected during routine clinical care. The primary endpoint is the change in Time in Range (TIR) between baseline and 6 months.
