Study of the Impact of PROximity Support for Patients With Type 1 DIABetes Treated With an Insulin Pump or Closed Loop.

Amidst medical innovations, many Type 1 diabetes patients using advanced therapy show improved control but still suffer from diabetes-related distress. To tackle this, the investigators propose an "enhanced care" model involving healthcare providers and pharmacists. The study compares standard and enhanced care for Type 1 adults, focusing on the pharmacist's role.

The main question it aims to answer is : In patients with type 1 diabetes treated with pump or closed-loop therapy, does the improved enhanced care versus conventional layout improve diabetes-related distress at 12 months?

Participants will complete a monthly online questionnaire to assess their diabetes-related distress as well as their frequency of use of standard and enhanced care as well as the associated patient satisfaction.

About this study

Amidst accelerating innovations in care and limited medical time, many patients with Type 1 diabetes treated by pump or closed-loop therapy appear to have improved glycaemic control, but still experience significant diabetes-related distress.

The investigators therefore propose that a new form of patient care service provided by a health service provider and the patient's pharmacist, as part of the new type of care called "enhanced care", could contribute to overcoming this challenge.

This study compares two different care services provided to adult patients with Type 1 diabetes (PwT1D) treated with an insulin pump or a closed-loop system, known as standard care and enhanced care, the main difference between which lies in the pharmacist's involvement in the enhanced care model.

The originality of this project lies in several points:

  • Firstly, it involves evaluating a new care model called enhanced care, which has the original feature of including the involvement of the patient's dispensing pharmacist.
  • The role of home support providers in the psychological aspects of diabetes is poorly documented in the scientific literature.

Diabetes-related distress is a well-known complication, but means of prevention remain inadequate. This study integrates live collection of patient data, by the patient. Patient experience is an innovative approach that plays an increasingly important role in the evaluation of new management approaches.

  • In addition to patient data, this study integrates data from pharmacists and physicians. These data will be used to compare the points of view of healthcare professionals and patients, in order to gain a precise idea of the service provided by the enhanced care. In itself, this comparison could contribute to identifying and understanding the difference in the points of view of healthcare professionals and patients.
  • While there is a wealth of literature demonstrating the value of pharmacist involvement in the care of Type 2 diabetic patients, such information is lacking for Type 1 diabetes. This study, aimed at investigating the impact of the pharmacist, specifically on the distress of patients undergoing highly technical treatment, is therefore original.
  • Finally, the design of this pragmatic, randomized study enables real-life practices to be analyzed, while maintaining the highest possible level of evidence.

Treatment and study plan

enhanced care model provided by Timkl, a home support provider

Other

A new type of care provided by timkl, a home support provider, involving nurses and the dispensing pharmacist. This approach combines the current tasks of the service provider's nurses with closer monitoring by the pharmacist, thanks to more frequent contacts and a holistic view of the patient.

Primary outcomes

  1. Change in the 7-question Type-1 Diabetes Distress Score (T1-DDS-7) [Comparison: Enhanced Care vs Standard Care]

    Time frame: Baseline visit (Month 0) to Final visit (Month 12)

    Compare patient-reported levels of diabetes-related distress at 12 months. Higher T1-DDS-7 scores indicate higher levels of diabetes-related distress.

Secondary outcomes

  1. A.1 Change in the 7-question Type-1 Diabetes Distress Score (T1-DDS-7) [Comparison: Enhanced Care vs Standard Care]

    Time frame: Baseline (Month 0) to Month 6

    Compare patient-reported levels of diabetes-related distress at 6 months. Higher T1-DDS-7 scores indicate higher levels of diabetes-related distress.

  2. A.2 Change in the sub-scores of the 7-question Type-1 Diabetes Distress Score (T1-DDS-7) [Comparison: Enhanced Care vs Standard Care]

    Time frame: Baseline (Month 0) to Month 12

    Compare the dimensions of patient-reported levels of diabetes-related distress individually at 12 months.

    Each question of the T1-DDS-7 reports a different dimension of diabetes-related distress.

    Higher sub-scores indicate higher levels of diabetes-related distress in their respective dimensions.

  3. A.3a Evolution of the 7-question Type-1 Diabetes Distress Score (T1-DDS-7) [Comparison: Enhanced Care vs Standard Care]

    Time frame: quarterly between Baseline (Month 0) and Month 12

    Time-series analysis of the evolution of T1-DDS-7 scores over the course of the 12-month observation period. T1-DDS-7 is assessed quarterly. Higher T1-DDS-7 scores indicate higher levels of diabetes-related distress.

  4. A.3b Evolution of the 2-question Diabetes Distress Score (DDS2) [Comparison: Enhanced Care vs Standard Care]

    Time frame: 8 times between Baseline (Month 0) and Month 12

    Time-series analysis of the evolution of DDS2 scores over the course of the 12-month observation period. Higher scores indicate higher levels of diabetes-related distress. DDS2 is every month during which the T1-DDS-7 is not.

    This time series will be used to complete the time-series of T1-DDS-7 scores.

  5. B.1a Patient overall satisfaction with services provided by the home support provider

    Time frame: monthly between Baseline (Month 0) and Month 12

    Overall satisfaction is assessed using a Visual Analog Score ranging from 0 to 10, with higher values indicating higher satisfaction.

  7. B.1c Satisfaction with specific aspects of the services provided by the home support provider

    Time frame: monthly between Baseline (Month 0) and Month 12

    • Were the interactions of an appropriate length?
    • Was the location of the interactions satisfactory?

  24. C.3b Patient perception of treatment burden [Comparison: Enhanced Care vs Standard Care]

    Time frame: Baseline (Month 0) and at Month 12

    The Timkl-1 questionnaire is a 9-question tool used to assess patients' treatment burden, need for an enhanced care service, and quality of life.

    This outcome uses the treatment burden subscore, for which higher scores indicate a greater burden.

  25. D.1 Time in the glycemic target range [Comparison: Enhanced Care vs Standard Care]

    Time frame: Month 12

    Time in the glycemic target range (Time-in-range or TIR) is an intuitive metric that denotes the amount of time in percentage that a person's glucose level remains within the proposed target range.

    Using measurements from continuous or flash glucose monitoring systems, TIR is the percentage of data points between 70 and 180 mg/dL.

    Complementary metrics are used:

    • Time below range (TBR) = percentage of data points < 54 mg/dL
    • Time above range (TAR) = percentage of data points > 180 mg/dL

  26. Percentage of glycated hemoglobin (HbA1c) [Comparison: Enhanced Care vs Standard Care]

    Time frame: at Baseline (Month 0) and at Month 12

    The HbA1c test is used to evaluate a person's level of glucose control. The test shows an average of the blood sugar level over the past 90 days and represents a percentage. Higher values tend to indicate worse levels of glucose control.

  27. E.1 Patient quality of life [Comparison: Enhanced Care vs Standard Care]

    Time frame: at Baseline (Month 0) and at Month 12

    The Timkl-1 questionnaire is a 9-question tool used to assess patients' treatment burden, need for an enhanced care service, and quality of life.

    This outcome uses the quality of life subscore, for which higher scores indicate a better quality of life.

  28. E.2 Number and relevance of impact that can have an impact on diabetes [Comparison: Enhanced Care vs Standard Care]

    Time frame: monthly between Baseline (Month 0) and Month 12

    • (intervention group) Number and relevance of clinical or non-clinical events reported by the patient to the pharmacist
    • Number and relevance of clinical or non-clinical events reported by patients to their specialist doctor
    • Number and relevance of clinical or non-clinical events reported by the patient (ePRO)
