Given the collaborative nature, physicians' perceptions of the APN role is important-systematic reviews found that a lack of physicians' understanding of the role was a potential barrier to APNs' practices (Andregård & Jangland, 2015;Fealy et al., 2018). Furthermore, a limited perception of the multiple APN roles was noted to stymie the APN scope of practice despite existing legislations expanding its practice (Poghosyan, Norful, & Laugesen, 2018).
