Brief summary

The purpose of this study is to evaluate treatment adherence among patients followed in the Department of Inherited Metabolic Diseases at Necker Hospital, in order to assess the need for implementing a therapeutic education workshop focused on medication adherence.

Detailed description

There is limited data in the literature regarding treatment adherence in children with metabolic disorders. A 2011 study on phenylketonuria highlighted a decline in dietary adherence during adolescence. Another study, dating from 1996 and focusing on urea cycle disorders, emphasized the importance of good treatment adherence for maintaining disease control. Furthermore, larger-scale research in epileptic patients has identified several barriers to treatment compliance, highlighting the crucial role of treatment adherence in improving disease control. The purpose of this study is to evaluate treatment adherence among patients followed in the Department of Inherited Metabolic Diseases at Necker Hospital, in order to assess the need for implementing a therapeutic education workshop focused on medication adherence.

Interventions

OTHERQuestionnaire

A pseudonymized questionnaire assessing treatment adherence, understanding of the illness, knowledge of medications, and the number of oral medications taken is given to patients and/or their parents during a follow-up visit, whether in a consultation, day hospital, or conventional hospitalization. It is completed by parents and children aged 7 and older, as well as by adolescents and young adults. The responses will not be disclosed to the physicians in the department.

OTHERCalculation of the metabolic balance score

For patients with urea cycle deficiency, a metabolic balance score will be calculated independently from retrospective data from the medical record, in the last two years preceding the completion of the questionnaire.
