To practice interprofessional collaboration (IPC), understanding the roles of each profession in the team is key. Anesthesia assistants (AAs) are a relatively new addition to the Canadian healthcare system. As a result, its role in the delivery of anesthesia care can be misunderstood by other healthcare professionals. Using an exploratory multiple case study design, this article explores healthcare professionals' perceptions of the AA role and its impact on patients and IPC. Sixteen semi-structured, in-depth interviews were conducted with a purposive sample of nine healthcare professions from inside and outside the peri-operative care unit in two urban, acute care, university-affiliated teaching research hospitals in Ontario. A thematic analysis of the interview transcripts identified five overarching themes: limited understanding of the AA role, improved patient-centred care, improve IPC and interprofessional education, ongoing challenges, and the future direction for professional growth. Results indicated that despite regular clinical practice collaboration, participants have a limited understanding of AAs in terms of their educational prerequisites, scope of practice, and roles. One reason for this lack of understanding is that there is a high variability of titles and clinical duties for non-physician anesthesia providers. The diverse range of anesthesia services provided by AAs can also become a barrier to the full understanding of their scope of practice and roles. The limited understanding of the AA role was reported as one of AAs' ongoing challenges. It prevents AAs from realising their full scope of practice. Participants suggested that AAs' professional growth should focus on promoting and expanding their role. Understanding other healthcare professionals' perceptions of AAs will assist them to become better ambassadors for their role, and to more effectively promote and practice IPC. Ultimately, this will result in improved interprofessional teamwork to deliver effective and efficient patient care.
