The present study is part of an overarching study being conducted in Denmark at Steno Diabetes Center Copenhagen (SDCC) and Nordsjællands Hospital Hillerød (NOH), Steno Tech, that aims to develop and ultimately, in a randomized controlled trial (RCT), test approaches that can assist people with type 1 diabetes in obtaining optimal outcomes using CSII. Through a large-scale, questionnaire-based online survey enriched with data from national registers, this sub-study contributes to this overarching aim by exploring the importance of individual differences across a wide range of factors, including demographic, socioeconomic, health status, psychosocial and preference structures, for optimal use of CSII in people with type 1 diabetes.
See attached protocol for a detailed description.
Study Type
OBSERVATIONAL

Glycated Hemoglobin A1c (HbA1c)
Information on HbA1c in mmol/mol will be extracted from national registers
Time frame: 13 years (from 2008 (beginning of register) to present)
Other diabetes-relevant biomarkers
Biomarkers included at the regular diabetes 'check-up' other than HbA1c including hemoglobin, eGFR, UACR, cholesterol total, HDL, LDL, VLDL, triglycerides and TSH will be extracted from national registers
Time frame: 13 years (from 2008 (beginning of register) to present)
General diabetes and insulin pump-specific behavior
Measured with single items in the survey
Time frame: 1 day (measured at one time point only, i.e., at the survey completion date for each participant)
Psychological well-being
Measured with the WHO5 questionnaire scale in the survey
Time frame: 1 day (measured at one time point only, i.e., at the survey completion date for each participant)
Diabetes distress
Measured with the Type 1 Diabetes Distress (T1-DDS) questionnaire scale in the survey
Time frame: 1 day (measured at one time point only, i.e., at the survey completion date for each participant)
Hypoglycemia anxiety
Measured with the Hypoglycemia Fear Survey short-form (HFS-SF) questionnaire scale in the survey
Time frame: 1 day (measured at one time point only, i.e., at the survey completion date for each participant)
