© 2018 Objectives: The Cystic Fibrosis (CF) International Mental Health Guidelines Committee published consensus statements for screening and treating depression and anxiety in individuals with CF and their caregivers. This work aimed to evaluate the dissemination and implementation of the guidelines in Europe two years following their publication. Methods: A 28-item survey was developed by the multidisciplinary ECFS Mental Health Working Group and emailed to approximately 300 CF centres across Europe. The survey evaluated (a) who should be responsible for mental health (MH) care, (b) the current awareness and agreement of the guidelines, (c) the provision of recommended MH screening and follow-up care, and (d) successes, barriers and required resources/training needs. Results: Responses were received from 187 centres (28 countries represented). There was consensus that a psychologist should be responsible for MH care, although members of the multidisciplinary team (MDT) believed they should also share this responsibility. Sixty-two percent of respondents were aware of the guidelines; 82% percent fully, and 12% partially, agreed with them. Fifty percent (94 centres) had implemented screening. In the past year approximately 6000 patients and 2000 caregivers had been screened, with 80% of respondents using the recommended screening tools. Respondents reported 551 referrals for moderate/severe psychopathology and 84 urgent suicide ideation referrals. Conclusions: The challenges of different healthcare systems and language barriers are being overcome with a greater awareness of the importance of mental health among the MDT. MH screening is feasible and gaining momentum in both Western and Eastern Europe.
