Evaluation of the implementation in primary care of genetic testing for the screening of MODY2 (iMOgene): protocol for an implementation pilot study.

INTRODUCTION

MODY2 (maturity-onset diabetes of the young type 2, MIM125851) is a monogenic diabetes with an autosomal dominant transmission caused by a variant of the gene. MODY2 is often confused with type 1 or type 2 diabetes, but despite a slightly elevated blood glucose level, it does not induce long-term vascular complications, nor does it require pharmacological treatment. Genetic testing for the diagnosis of MODY2 is currently reserved for genetic specialists and some physicians. Still, access to it by primary care healthcare professionals (HCPs), coupled with appropriate training, would improve the diagnosis and management of patients with MODY2. Thus, to evaluate the implementation in primary care of genetic testing for the screening of MODY2 (iMOgene study), an implementation pilot study has been designed supported by the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework.

METHOD AND ANALYSIS

Two primary care clinics will be involved in the region of Saguenay-Lac-Saint-Jean (Québec, Canada). An asynchronous online training on MODY2 and genetic testing, including pre/post questionnaires, will be provided to the HCPs. Satisfaction, adoption and maintenance indicators will be collected throughout the project for each clinic. Questionnaires for patients and professionals and focus groups with HCPs will be conducted to assess implementation. This study will document the implementation process of genetic testing in primary care by identifying facilitating and limiting factors to establish specifications for scaling up.

ETHICS AND DISSEMINATION

The present protocol has been approved by the research ethic committee of the 'C (CIUSSS-SLSJ) on 9 January 2024 and by the 'C' (CCER) of the '' of Quebec (Canada) on 30 January 2024. The informed consent of participants will be obtained orally. Dissemination of the study results will involve peer-review publications, presentations at major national and international scientific conferences.
