Purpose: Person-centred goal setting with people with brain injury, by interdisciplinary teams has benefits including improved communication between patients, families and clinicians, person-centred care, and improved engagement in rehabilitation. Exploring the experiences of team members who have adopted interdisciplinary, person-centred goal setting may assist in understanding what is needed to implement this complex, core component of rehabilitation practice. This study explored experiences of clinicians working in an extended inpatient brain injury rehabilitation unit about implementing a role-based goal planning approach within an interdisciplinary team. Materials and methods: Semi-structured interviews with 13 clinicians working at the rehabilitation unit explored their experiences about the cognitive participation and collective actions required to carry out the practice, with data analysed using inductive content analysis guided by Normalisation Process Theory. Results: Three primary themes were identified: putting the person at the centre, accepting the mind-shift to participation focused goals and working collaboratively. Conclusions: This study has elucidated some key processes that occurred and were necessary to carry out goal setting. A mind-shift towards holistic, participation-focussed goal setting was described as “unlearning” discipline-specific goal setting. Development and ownership by the team, acceptance of team members and willingness to share, and structured processes and resources were necessary.IMPLICATIONS FOR REHABILITATION Normalising interdisciplinary role-based goal setting in multi-professional teams requires a mind-shift away from traditional, discipline-specific goal setting. Implementation of interdisciplinary, collaborative team goal setting within health service settings requires collective actions including collaborative working by team members, structured processes including organised time for collaborative team and family meetings, practical resources and training to support processes. Clinicians perceived the goal setting approach to put the person at the centre resulting in a deep understanding of the person, shared understanding, and motivation for rehabilitation.
