Diabetes mellitus prevalence and continuous glucose monitoring use in Portugal: A modified Delphi consensus study
By Joana Torres, Filipa Ramilo‐Gomes, Hugo Pedrosa and 6 others.
Abstract
Introduction
With one of the highest prevalence rates in Europe, diabetes mellitus (DM) poses a significant public health and economic challenge in Portugal. However, current data on its prevalence and glucose monitoring practices remain scarce. This study aimed to establish expert consensus on the current DM epidemiology landscape in Portugal, evaluate current glucose test strips and continuous glucose monitoring (CGM) sensor utilisation patterns, and gather insights about the tools using AI for DM management.
Methods
A modified Delphi methodology was employed, involving two rounds of expert consultation with five diabetes specialists across Portugal in 2025. The panel assessed structured questionnaires covering DM prevalence, CGM sensor and test strip utilisation patterns, and insights about silico studies for AI-mediated DM management. Anonymised responses were discussed in a moderated virtual session to reach consensus.
