Authors' conclusion

AID-URAI slightly improves the percentage of TIR and has a good safety profile without increasing the risk of diabetic ketoacidosis and severe hypoglycemia.

Study context

Population
Patients with T1D; databases searched up to 30 October 2024
Participants

Comparison
Automated insulin delivery (AID) with ultra-rapid-acting insulin analogues (AID-URAI) vs AID with rapid-acting insulin analogues (AID-RAI)
Outcome
Percent TIR (3.9-10 mmol/L)

Further pooled results

Time-in-range (TIR) in subgroups

Favourable effect consistent in AID with automated bolus correction, adults, study duration >4 weeks and FIASP subgroups

Percent time-below-range (TBR) (<3.9 mmol/L)

Lower percentage of TBR with AID-URAI vs AID-RAI
0.35%

Safety

No significant differences in risk of DKA and severe hypoglycaemia between groups
