Associations between insulin pump self‐management and HbA1c in type 1 diabetes
Authors' conclusion
Self-adjusting insulin pump settings, optimal timing and few omissions of meal boluses, and timely change of infusion set are associated with lower HbA1c.
Study context
- Population
- Adult insulin pump users with T1D; 60% women, median age 49 years, median diabetes duration 25 years699 eligible responders
- Participants
- 770 users

- Outcome
- Associations between self-management factors (advanced features, infusion set change timing, meal bolus timing, data-upload, pump settings adjustments) and HbA1c
Methodological detailsonline questionnaire, national registry data, backward selected linear regression

Main finding
As reported in the abstract
HbA1c
- Infusion set change every 0-4 days vs 5-10 days
- −5 mmol/mol (−0.4%); P = 0.003
- Never/rarely missing a bolus vs Often missing a bolus
- −6 mmol/mol (−0.5%); P < 0.001
- Insulin 10-15 min before meal vs After meal start · lower HbA1c
- −3 mmol/mol (−0.3%); P = 0.023
- Self-adjusting pump settings vs Health care professionals doing all adjustments · strongest association with lower HbA1c
- −6 mmol/mol (−0.6%); P < 0.001
Observational data: associations, not effects.
