ObjectivesThis study aimed to: (1) understand the context for delivering a trauma vocational rehabilitation (VR) intervention; (2) identify potential barriers and enablers to the implementation of a VR intervention post-trauma.DesignQualitative study. Data were collected in person or via phone using different methods: 38 semistructured interviews, 11 informal ‘walk-through care pathways’ interviews, 5 focus groups (n=25), 5 codesign workshops (n=43). Data were thematically analysed using the framework approach, informed by the Consolidated Framework for Implementation Research.SettingStakeholders recruited across five UK major trauma networks.ParticipantsA variety of stakeholders were recruited (n=117) including trauma survivors, rehabilitation physicians, therapists, psychologists, trauma coordinators and general practitioners. We recruited 32 service users (trauma survivors or carers) and 85 service providers.ResultsThere were several issues associated with implementing a trauma VR intervention including: culture within healthcare/employing organisations; extent to which healthcare systems were networked with other organisations; poor transition between different organisations; failure to recognise VR as a priority; external policies and funding. Some barriers were typical implementation issues (eg, funding, policies, openness to change). This study further highlighted the challenges associated with implementing a complex intervention like VR (eg, inadequate networking/communication, poor service provision, perceived VR priority). Our intervention was developed to overcome these barriers through adapting a therapist training package, and by providing early contact with patient/employer, a psychological component alongside occupational therapy, case coordination/central point of contact, and support crossing sector boundaries (eg, between health/employment/welfare).ConclusionsFindings informed the implementation of our VR intervention within the complex trauma pathway. Although we understand how to embed it within this context, the success of its implementation needs to be measured as part of a process evaluation in a future trial.
