AimTo analyse how nurses describe their interactions with other interdisciplinary team members within stroke and geriatric rehabilitation.DesignA secondary analysis of cross‐sectional ethnographic interview data was conducted using Elo and Kyngäs' (2008) deductive content analysis.MethodsBetween April 12 and July 25, 2022, semi‐structured interviews were conducted with 31 registered practical nurses recruited through convenience sampling from three tertiary hospital sites in Southwestern Ontario. Interview transcripts were reviewed to identify described interactions between nurses and interdisciplinary team members and were coded for: who were the interdisciplinary team member(s) involved; what content was addressed; and where, when, and why the interaction occurred.ResultsCategories representing how nurses describe their interactions with interdisciplinary team members were as follows: (1) arising from the unique roles owned by either the nurse or interdisciplinary team member(s); (2) requiring open communication to achieve patient goals and improve patient care; (3) occurring within what is perceived to be either the therapists' or nurses' physical space; and (4) contributing to supportive team environments that are mutually beneficial.ConclusionsWhile nurses view other interdisciplinary team members as ‘owning’ certain roles and physical spaces within rehabilitation, they also recognised their ‘owned’ spaces and roles. Unique contributions of all team members were valued as necessary to provide holistic, person‐centred patient care and positive team‐based support.Implications for the Profession and/or Patient CareNurses' descriptions of their interactions with interdisciplinary team members demonstrated their essential contributions to team‐based patient care and acknowledged nurse contributions to the rehabilitation process for patients.ImpactFindings elucidate the nature of interprofessional interactions and ‘ownership’ within the rehabilitation process. Results are beneficial for policymakers, educators, and healthcare organisations aiming to optimise the nursing role within rehabilitation spaces.Reporting MethodThe Consolidated Criteria for Reporting Qualitative Research Checklist (COREQ).Patient or Public ContributionNo patient or public contribution.
