Abstract
Purpose: To explore perspectives and experiences regarding the autonomy of physiotherapist assistants (PTAs) among physiotherapists and PTAs providing home care services in Ontario since the introduction of PTAs into home care rehabilitation teams. Method: For this qualitative study, we conducted semi-structured interviews with 10 physiotherapists and 5 PTAs working in home care. We analyzed interview transcripts using the DEPICT model. Results: Participants described navigating a grey zone characterized by a lack of clarity about acceptable levels of PTA autonomy. Four interrelating factors shaped the extent to which PTAs practised with autonomy: system influences (number of physiotherapy visits, professional guidelines), patient complexity (status, comorbidities), perceived PTA competence (skills, training), and the physiotherapist-PTA relationship (trust, communication). Conclusions: New practice models in home care have impacted the role of both physiotherapists and PTAs. Home care agencies should facilitate emerging professional relationships and address autonomy-related challenges, such as trust and competence, to promote high-quality client-centred care.
