Title {1}
| Organisational models supported by technology for the management of diabetic disease and its complications in a diabetic clinic setting. Study protocol for a randomised controlled trial targeting type 2 diabetes individuals with non-ideal glycemic values (Telemechron study) |
Trial registration {2a and 2b}
| ClinicalTrials.gov NCT05629221 [Registered on November 29, 2022 prior start of inclusion] |
Protocol version {3}
| Version 2 of 27–09-2022 First issue date: 11 May 2022 (8 August 2022) Approved by Ethics Committee: 30 May 2022 (Amendment: 27 September 2022) (Ethics Committee opinions are available as Additional File 1) Primary reason for amendment: The trial initially aimed to recruit T2DM individuals with non-ideal glycemic values, also affected by post-infarction cardiomyopathy and/or heart failure. It was soon realised that the criteria of being both diabetic and with a heart condition would have compromised the recruitment process and no targeted sample size would have been reached in time. Therefore, the following two inclusion criteria were removed: (1) having a diagnosis of ischemic heart disease identified by a previous documented acute ischemic event requiring an hospital access or a diagnosis of ischemic heart diseases following a positive test for inducible ischemia, or (2) having a diagnosis of heart failure with a New York Heart Association (NYHA) Classification of Heart Failure I or II or III (reduced or preserved ejection fraction) [1] defined on the basis of a previous hospitalisation for heart failure, or defined by an ejection fraction below 50% and NYHA I or II or III (absence of dyspnoea at rest) Before the first version of the protocol was approved, Ethical Committee made the following requests: i) improved description of the intervention; ii) clarification related to the Regulation (EU) 2017/745 of the European Parliament and of the Council of 5 April 2017 on medical devices, that is, clarifying that TreC Diabete is not a medical device [2]; iii) amendment to the informed consent form to further simplify the wording (available in English upon request) |
Funding {4}
| This trial is funded by the Department of Health of the Italian National Health System in the context of the “Ricerca finalizzata (Bando della ricerca finalizzata year 2018)—National Research (Bandi/Call 2018)”. The TreC Diabete platform was designed and implemented by the Bruno Kessler Foundation (FBK), Italy. The platform is formally distributed by the Azienda Provinciale per i Servizi Sanitari (APSS). This is described in greater details in Additional File 2 |

Interventions
Intervention description {11a}
Level | Feature | Description |
---|---|---|
Dashboard (prescriber) | Activation of credentials for the participant | The feature allows to activate the App for a specific participant and is performed by the clinicians via dashboard |
Dashboard (prescriber) | Setup of the data each participant will be required to enter into the App | The feature allows the clinician to decide which data the participant will be asked to enter by the App. It allows the storage of the data and the sharing of information |
Dashboard (prescriber) | Display of data | The feature allows the user to view the data as entered by the participant. It allows the sharing of the information, which cannot be altered or modified |
Dashboard (prescriber) | Activation and use of a chat between clinicians/healthcare staff and participants | The feature allows the user to activate a chat for remote contact and communication between clinicians and participants. Different types of information could be shared through this channel (including files and pictures) |
Dashboard (prescriber) | Personalised activation of tasks based on the diabetes profile | The feature allows the clinician to assign tasks and related reminders regarding the insertion of certain parameters, such as weight, blood pressure, glycaemia, with a defined frequency, time of the day of execution and related deadlines. The function allows the memorisation and the communication of information |
Dashboard (prescriber) | Setup of reminders related to drugs | The feature allows the clinicians to set reminders regarding specific drugs and healthy lifestyle behaviours. It is considered a function that allows the communication of information |
Dashboard (prescriber) | Set up of a blood glucose profile | The feature allows the clinician to insert the participant’s blood glucose profile for informational purposes only |
Dashboard (prescriber) | Set up of ordinary reports | The feature allows the doctor to receive regular reports produced by the App and based on the data inserted by the participant at specific intervals. The data are shown as aggregated and cannot be modified |
App (participant) | Chat between clinicians and participant | The feature allows the participant to send messages to the clinician for remote contact and communication |
App (participant) | Activation of the diary of personal observations | The feature allows the participant to enter and review the parameters inserted for the activated tasks. Reminders may be activated (without push notifications). Participants can enter and insert other unassigned parameters. The insertion is done directly by the participant. The diary is not directly visible to the clinician through the dashboard with the exception of the prescribed parameters |
App (participant) | Activation of the drugs’ diary | The feature allows the participant to manually record the intake of drugs (either prescribed or not by the clinician) |
App (participant) | Set up of reminders | The feature allows the participant to receive notifications (push) concerning telemedicine appointments |

-
Effect on weight, lipid profile and BP levels for the App users;
-
Effect on physical activity performed during the last 7 days prior filling in the questionnaire, for both arm participants;
