Abstract Little is known about physician perceptions of nurse practitioners (NPs) and physician assistants (PAs) on hospitalist teams and the factors that impact their perceptions. Academic physician hospitalists were surveyed to better understand those factors, focusing on NP/PA experience, training, and physician experience with NPs/PAs. Perceptions by hospitalist physicians of NPs/PAs were strongly positive. Notable findings include the perceived positive impacts of NPs/PAs on clinical care provided, practice efficiency, and physician satisfaction. Most respondents prefer working with NPs and PAs with multiple years of clinical experience, particularly those who have participated in training beyond NP/PA graduate programs of study.
