Communities of practice can facilitate the sharing and translation of knowledge. BRAINSPaN is a multidisciplinary community of practice of clinicians, researchers and students in the brain impairment field that was launched in Australia in June 2017. We aimed to investigate the impact of BRAINSPaN on multidisciplinary collaboration and on knowledge, skills and confidence in domains of practice of interest to members.

We surveyed BRAINSPaN members over three time points at 1-month (n = 117), 7-months (n = 69) and 14-months (n = 46) post-launch. Content analysis of posts to the BRAINSPaN listserv was also conducted to identify their purpose and content.

Increasing access to new research findings and increasing interaction with others in the brain impairment field were the two main goals for survey respondents’ participation in BRAINSPaN. At 7- and 14-months post-launch, these were also the most commonly achieved goals and most frequently cited benefits of BRAINSPaN participation. Cognitive rehabilitation and behaviour management were the most frequently reported practice domains of interest, as well as being two of the five most common topics of BRAINSPaN posts over the survey period. There was a significant increase in self-reported knowledge for participants’ top two domains of interest, but no change in skills or confidence.

BRAINSPaN has the potential to serve as a vehicle for the sharing and translation of knowledge in the brain impairment field. Combining other forms of dissemination with communities of practice, such as workshops and clinical mentoring, may be needed to also influence the development of skills and confidence in practice areas.
