Background: Oncology practices are increasingly employing nurse practitioners (NPs) and physician assistants (PAs) known collectively as advanced practice providers (APPs) to improve practice workflow, increase efficiency, and enable physicians to focus on complex patient care. Understanding variations in scope of practice for APPs may help establish a benchmark against which future changes are measured. Methods: US community physicians responded to a web-based survey from Sep to Nov 2018. Physicians were asked how frequently their APPs performed certain tasks on a 5-point scale (i.e., never, occasionally, sometimes, frequently, and always). Responses have been summarized using descriptive statistics. Results: In this study, 163 physicians were surveyed, most (81.0%, n = 132) used APPs in their practice. Among physicians using APPs, 91.7% (n = 121) used NPs and 49.2% (n = 65) used PAs. Most physicians stated that APPs were frequently/always involved in providing patient education (84.1%), ordering imaging and laboratory studies (68.9%), and/or making supportive care decisions (62.1%). Over 85% (57.6%-59.8% occasionally/sometimes; 28.0%-28.8% frequently/always) of physicians agreed that APPs discussed imaging reports and end of life (EOL) care (57.6% occasionally/sometimes, 28.8% frequently/always) with patients. Regarding procedures: 51.9% (28.0% occasionally/sometimes; 24.1% frequently/always) responded that APPs performed bone marrow biopsies and intrathecal chemotherapy. Regarding systemic therapy: 68.2% (58.3% occasionally/ sometimes; 9.8% frequently) allowed APPs to modify existing regimen e.g., dose/schedule change; 39.4% responded that APPs made decisions about new therapy selection. Conclusions: While substantial variation in the role of APPs in community oncology practices was observed, similar themes emerged. APPs appear to be integral in patient education, ordering laboratory and imaging studies, and discussing EOL care. Fewer are involved in managing and selecting supportive care and systemic therapy. Longitudinal and longer follow up are warranted to ascertain whether the scope of these practices change over time.
