One such intervention has been provided for seven years within a region in England. This study reports upon the implementation process and fidelity of this intervention. Methods The process evaluation guidance issued by the Medical Research Council has informed this study. A logic model to describe the intervention and causal assumptions was developed from preliminary semi-structured interviews with project team members. Further semi-structured interviews were undertaken with intervention providers from hospital and community pharmacy, and with patient and public representatives. These aimed to investigate intervention implementation process and fidelity. The Consolidated Framework for Implementation Research and the Consolidated Framework for Intervention Fidelity informed interview topic guides and underpinned the thematic framework analysis using a combined inductive and deductive approach. Results Themes provided information about intervention fidelity and implementation that were mapped across the sub processes of implementation: planning, execution, reflection and evaluation, and engagement. Interviewees described factors such as lack of training, awareness, clarity on the service specification, governance and monitoring and information and feedback which caused significant issues with the process of intervention implementation and suboptimal intervention fidelity. Conclusions This provides in-depth insight into the implementation process and fidelity of a ToC intervention, and the extant barriers and facilitators. The findings offer learning to inform the design and implementation of similar interventions, contribute to the evidence base about barriers and facilitators to such interventions and provides in-depth description of the implementation and mechanisms of impact which have the potential to influence clinical and economic outcome evaluation.
