Brief summary
This study is a randomized, controlled, prospective trial with a 6-month follow-up. A newly developed treatment and education programme for diabetic patients with an insulin pump therapy (INPUT) will be tested compared to a waiting group. Primary outcome variable is the difference in glycemic control between baseline and the 6-month follow-up. Secondary outcome variables are: severe hypoglycaemia, diabetes-related distress, depressive symptoms, health-related quality of life, diabetes empowerment, self-care behavior, hypoglycemia awareness, and attitudes towards insulin pump therapy.
Detailed description
INPUT is a self-management-based treatment and education program for diabetic patients with an insulin pump (CSII). It is designed to empower patients to adequately perform their therapy in daily life and to integrate their diabetes and their insulin pump into their lifes in order to enhance quality of life. INPUT ist tested in an randomized controlled trial (RCT) with a waiting-list control group since no certified and effective treatment and education program for CSII exists. This study is a multi-center study. Study centers are specialized diabetes practices throughout Germany. Patients will be approached by their respective practice and informed about the study. Study measurements as well as the conduct of INPUT will take place at the respective practice. Baseline measurement will take place 2 weeks prior to the beginning of INPUT. After completion of baseline measurement, all patients from one study center will be randomized centrally by the Research Institute of the Diabetes Academy Mergentheim (FIDAM). 2 weeks and 6 months after the completion of INPUT, follow-up measurements will be conducted at the respective study center. HbA1c as a marker of glycemic control will be analyzed in a central laboratory. Secondary outcome measures will be assessed via psychometrically tested questionnaires, Case Reports Forms, or patient files.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in Glycemic Control Measured by A1c | 6 months | Difference between baseline A1c and A1c at the 6-month follow-up |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Diabetes Empowerment | 6 months | Empowerment is measured by a German version of the Diabetes Empowerment Scale, a measure of diabetes-related psychosocial self-efficacy. |
| Satisfaction with current treatment | 6 months | Satisfaction with current treatment is assessed via a 10-item scale. The total score ranges from 10 to 60 with lower scores indicating higher satisfaction. |
| Diabetes Self-Management | 6 months | The Diabetes Self-Management Questionnaire is a self-report measure of patients' self-care. The level of self-care is assessed via Likert scales. |
| Diabetes Distress | 6 months | The Diabetes Distress Scale (DDS) assesses diabetes-related stressors due to living and treating diabetes. Different aspects of distress are covered: emotional burden, physician-related, regimen-related, diabetes-related interpersonal |
| Hypoglycaemia Awareness | 6 months | The hypoglycemia awareness questionnaire provides a score indicating the severity of hypoglycaemia unawareness. This scale ranges from 0 (maximum hypoglycaemia awareness) to 7 (minimum hypoglycaemia awareness), where a score of 4 suggests reduced hypoglycaemia awareness. |
| Health-related Quality of Life | 6 months | Health-related quality of life focuses on the health-specific aspects of quality of life and dealing with a chronic condition such as diabetes |
| Depressive symptoms | 6 months | The presence and extent of typical depressive symptoms are assessed via self-report |
| Attitudes towards insulin pump therapy | 6 months | Specific attitudes towards different aspects of insulin pump therapy are assessed via Likert scales. The questionnaire consists of 6 subscales that can be placed within 4 dimensions: (I) Expectations on insulin pump therapy (subscale: achieving better glycaemic control) (II) Perceived advantages of an insulin pump (subscale: gaining more flexibility) (III) Ease of use (subscales: design + functionality) (IV) Psychosocial effects and barriers (subscales: technological dependence + impaired body image) |
| Severe hypoglycaemia | 6 months | The incidence of severe hypoglycaemia in the past six months is assessed via Case Report Forms. Severe hypoglycaemia is defined as requiring third party assistance or medical intervention for treating hypoglycaemia. |
| Problem Areas in Diabetes | 6 months | The Problem Areas in Diabetes Scale (PAID) assesses the psychosocial adaptation to the burden of living with and treating diabetes. |
