GPs' perceptions of the IDF-DAR risk score for fasting during Ramadan among patients with diabetes in Northern France

Fasting during Ramadan poses major challenges for patients with diabetes, who are at risk of glycaemic imbalance. To assist clinicians, the International Diabetes Federation (IDF) and the Diabetes and Ramadan (DAR) Alliance developed a risk score to guide fasting decisions. However, little is known about how this tool is perceived or used by French GPs.

To explore GPs' perceptions of the relevance, acceptability, and barriers to the use of the IDF-DAR risk score in assessing fasting risk among patients with type 1 or type 2 diabetes.

A cross-sectional, quantitative online survey conducted among community-based GPs in the Hauts-de-France region between March and June 2025. The questionnaire assessed knowledge, perceived relevance, ease of use, and willingness to implement the score in clinical practice. Descriptive and bivariate analyses were performed.

A total of 106 GPs participated. Knowledge of the IDF-DAR score was limited (6%), and its use was rare (2%). However, 89% of respondents considered it relevant, and 95% felt it could enhance doctor-patient dialogue. Perceived relevance was significantly associated with ease of use (p <0.001), clarity of it (p = 0.0035), and its educational value for patients (p <0.001). Despite low awareness, 89% expressed willingness to use it in the future; lack of information was the main barrier.

The IDF-DAR risk score appears useful for structuring pre-Ramadan risk assessments in diabetes care, but greater dissemination and training are needed to support its adoption in primary care.
