Client-responsive behaviours occur commonly among residents in long-term care (LTC) settings; direct-care staff, however, receive little education, support, or opportunities to discuss and collaborate on managing such behaviours. Our participatory action project introduced mental health huddles to support staff in discussing and managing client-responsive behaviours in long-term care. This research project engaged direct-care staff (e.g., personal support workers, registered practical nurses, housekeeping staff, and registered nurses) in learning how to use these huddles. Staff workers used huddles as a forum to stay informed, review work, problem solve, and develop person-centered action plans. Fifty-six huddles occurred over a 12-week period; two to seven direct-care staff participated in each huddle. Focus groups indicated improved staff collaboration, teamwork, support, and communication when discussing specific responsive behaviours. Huddles provided LTC staff with the opportunity to collaborate and discuss strategies to optimize resident care. Further research on how huddles affect resident care outcomes is needed.
