Number of Participants With Satisfaction Regarding the Management in General, at Day 30 and Day 90, by the CSQ-8 Questionnaire Primary · Day 30 and Day 90

Satisfaction regarding the management in general was assessed using the Client Satisfaction Questionnaire (CSQ-8). CSQ-8 is a validated questionnaire that measures patients' overall satisfaction with their management in general. It contains 8 questions and each question is answered using a 4-point scale. The score ranges from 8 to 32, with higher values indicating higher satisfaction. Patients were considered as satisfied if they reached a score above 20 points.

Number of Participants With Maintenance of Global Patient Satisfaction Regarding the Management in General, at Day 90, by the CSQ-8 Questionnaire Primary · Day 90

Satisfaction regarding the management in general was assessed using the Client Satisfaction Questionnaire (CSQ-8). CSQ-8 is a validated questionnaire that measures patients' overall satisfaction with their management in general. It contains 8 questions and each question is answered using a 4-point scale. The score ranges from 8 to 32, with higher values indicating higher satisfaction. Satisfaction was defined by a score above 20 points. Maintenance of satisfaction is measured on D90 by a score above 20 points which has not decreased by more than 4 points compared with D30.

Description of Patient Satisfaction and Experience Regarding the Management by HHP at Day 30 and Day 90 Primary · Day 30 and Day 90

The questionnaire was developed for the study by the French Diabetes Federation, aiming at evaluating patient satisfaction and experience with their management by the HHP. 16 questions assessed the proactiveness, availability and HHP nurse advice. A global score ranging from 13 to 57 was calculated, with higher values indicating higher satisfaction. The global score was only calculated when all questions were answered.

Quality of Life Questionnaire (EQ-5D) Summary Index at Inclusion, Day 30 and Day 90 Secondary · At inclusion, Day 30 and Day 90

The patient's quality of life was assessed by the quality of life questionnaire (EQ-5D-5L), validated in French Language. It is composed of 5 items each corresponding to a specific dimension (mobility, self-care, usual activities, pain/discomfort and anxiety/depression) and divided into 5 levels of perception (1. no problem, 2. slight problems, 3. moderate problems, 4. severe problems, 5. extreme problems/incapacity). The digits for the 5 dimensions were combined in a 5-digit code describing the patient's health state and were converted into a summary index value using the french value sets. T

Beliefs About Medicines Questionnaire (BMQ) Scores at Inclusion and D90 Secondary · At inclusion and Day 90

The patient's beliefs about the medical treatment were assessed by the specific section of the BMQ (Beliefs about Medicines Questionnaire), validated in French for diabetes. The specific BMQ consists of two parts: Part one contains five questions related to the need for the treatment and part two contains five questions on concerns about the prescription. The 10 questions are answered using a 5-point scale (1. strongly disagree, 2. disagree, 3. uncertain, 4. agree and 5. strongly agree). The results take the form of two scores ranging from 5 to 25, with higher value indicating higher need/conc
