Adherence to medication is important for successful CF management.  \nObjective: To describe medication adherence according to age, therapeutic class, and pharmaceutical form in adults and children followed in four regional CF centers in France. Methods: We conducted a cross-sectional study with non-transplanted patients followed in two adult and two pediatric centers during 2015 who were covered by the French National Health Insurance (NHI) . Sociodemographic, clinical, hospitalization, and prescription data were collected from patient medical records. Medication dispensations were extracted from the regional French NHI database. Adherence was calculated over 12 months using continuous medication availability (CMA) accounting for dose adjustments and hospitalizations. Drug-specific CMA was computed in R with the AdhereR package for each medication prescribed more than 3 months, which was averaged to obtain a composite CMA score (cCMA) for all treatments and per therapeutic class as well as pharmaceutical form for each patient.  \nResults: A total of 228 patients were included. The number of chronic medications increased with age (r=0.50, p\u003C0.001): a median of 7 medications per patient were prescribed. The mean±SD cCMA was significantly different between age groups (p=0.0098): it was 0.71 ±0.20 for the 0–5 years age group, 0.73±0.16 for 6–11 years, 0.64±0.17 for 12–17 years, 0.57 ±0.23 for 18–25 years, and 0.65±0.20 for the over 25 years age group. cCMA varied significantly according to pharmaceutical forms: the mean±SD cCMA was 0.70±0.21 for oral medications and 0.54±0.28 for inhaled medications (p\u003C0.001) .  \nConclusion: This study suggests that adherence to medication regimens in CF patients remains suboptimal and varies substantially between age groups and pharmaceutical forms. These variations in adherence should be considered when developing effective strategies to improve adherence.  \nKeywords: cystic fibrosis, chronic treatment, medication adherence, administrative claims data, prescription data  \nBackground  \nCystic fibrosis (CF) is a life-shortening inherited disease that usually affects several organs, although pulmonary disease predominately con","cbCaiqyqrvt7cQvn","https://ap.wps.com/l/cbCaiqyqrvt7cQvn","pdf",702729,14,"English","# Background\n# Objective\n# Methods\n# Results\n# Conclusion","[{\"question\":\"How was medication adherence measured in this study?\",\"answer\":\"Adherence was calculated over 12 months using continuous medication availability (CMA), accounting for dose adjustments and hospitalizations.
