Type 1 diabetes is a chronic autoimmune disease that often presents with diabetic ketoacidosis at diagnosis. Since detection of type 1 diabetes risk is possible using genetic risk scores and autoantibody assays, prevention of diabetic ketoacidosis or delayed onset of type 1 diabetes may be possible and may improve outcomes. Several pilot screening programmes for type 1 diabetes risk have emerged worldwide but outcomes measured in these screening programmes are heterogeneous, making it difficult to compare and synthesise findings across studies. To improve the standardisation of outcome reporting and measurement, we aim to develop a patient-oriented core outcome set for studies of type 1 diabetes risk screening.

This five-step protocol was developed in alignment with the COS-STAndardised Protocol Statement and the Core Outcome Measures in Effectiveness Trials framework. The five steps will include: (1a) conducting a rapid literature review, (1b) gathering input on candidate outcomes from members of the public, (2) combining literature and public input to prepare a preliminary list of outcomes, (3) conducting Delphi surveys with a range of stakeholders to begin to establish consensus on outcomes, (4) holding a final consensus meeting to establish consensus on outcomes and (5) establishing the outcome measurement instruments for the core outcome set.

Ethics approval has been provided by The Hospital for Sick Children Research Ethics Board. The core outcome set will be distributed to researchers and clinicians involved in diabetes screening and clinical care, patient and family networks, research funders, journal editors, public health experts, and policymakers. Disseminated materials will be tailored to the various end users in the form of publication through academic journals, policy briefs, conferences, educational webinars, websites and social media.

Guideline-directed medical therapy (GDMT) for heart failure (HF) reduces adverse events, but is underused. Global barriers to GDMT optimisation include low frequency of visits, clinician inertia and poor patient knowledge, which may be mitigated by digital health interventions (DHI). In Brazil, low digital literacy and reduced access to technology may compromise these potential DHI’s beneficial effects. Our objective is to develop and test the effectiveness of a DHI to optimise GDMT in patients recently hospitalised for HF in the Brazilian public health system (Sistema Único de Saúde (SUS)).

This is a randomised, controlled, multicentre, parallel-group, clinical trial in which 154 patients being discharged from an HF-related hospitalisation will be randomised. Inclusion criteria are ≥18 years of age, reduced ejection fraction HF (EF

This study was approved by the Universidade Federal de Minas Gerais. Recruitment started in November 2023, and patients involved will sign an informed consent form. Results will be presented at scientific meetings and published in scientific journals in 2025, and will be disclosed in social media and presented to public health stakeholders.
