Background: The CRESTA fatigue clinic was established in 2013 to fulfil the unmet needs of patients with long-term conditions and the symptom of chronic fatigue who did not have access to fatigue management support. The service was previously evaluated using a group concept mapping (GCM) approach and found to successfully meet patients' expectations. To ensure these needs continued to be met following change to the original service model, we re-evaluated the service using a similar approach. GCM is a mixed method approach. Statements are generated from stakeholders, sorted into themed clusters, and then rated. Method: 146 assessment tools wer e posted to consecutive clinic patients containing statements generated during the original study. Patients rated each statement for 'current success' on a 1-5 Likert scale and provided for free-text feedback. Unpaired t-tests were used to compare cluster success scores from both the previous evaluation and the current cohort of patients. Thematic analysis was used to evaluate the qualitative comments. Results: 46 questionnair es wer e r etur ned. Compar i-A comprehensive service re-evaluation of the UK's first NHS generic fatigue clinic four years following its inception: a mixed methods study
