Interprofessional collaboration is understood to improve efficiencies and quality of care but is associated with challenges such as professionals’ differing routines, knowledge, and identities, as well as professional hierarchies and time constraints. Given these challenges, there is limited understanding of how professionals collaborate effectively in providing patient-centred care. This study, with a convergence triangulation mixed-methods study design, explored interprofessional staffs’ perceptions of interprofessional collaboration and patient-centred care when working with hospitalized older adults. Thirty-six staff responded to a survey which included the Patient-Centred Care measure and the Modified Index of Interdisciplinary Collaboration; we also interviewed 14 nursing staff. Although all scores suggested a high value was placed on interprofessional collaboration, scores were low related to activities that facilitated team processes. We identified three themes from the data: knowing the patient/family, functional needs, and communication processes. Staff identified daily rounds with interprofessional teams as supportive of interprofessional collaboration and patient-centred-care.
