Background: The role of advanced practice providers (APPs), nurse practitioners (NPs) and physician assistants (PAs), is expanding in oncology for myriad reasons including improving access to care by closing the gap between demand for services and physician availability. This is especially true in oncology, where the shortage of oncologists and increasingly cited physician burnout is creating challenges for many practices and communities. Methods: We surveyed US physicians to understand their practices’ use of APPs, their role in patient treatment and support as well as their impact on practice workflow. Data were collected using web-based instrument between Sep 2018 and Nov 2018. Responses have been summarized using descriptive statistics. Results: Among 163 oncologists and hematologists surveyed, 74.2% (n = 121) employed NPs, 39.9% (n = 65) employed PAs, and 19.0% (n = 31) did not employ any APPs in their practice. Amongst practices that employed ≥1 APP (n = 132; 81.0%), over 40% of physicians reported a 1:3 APP: physician ratio. Most (62.1%) physicians stated that APPs only evaluated and saw returning patients, whereas 35.6% physicians used APPs to evaluate and see both new and return patients. More than 60% of physicians stated that APPs enhanced their practice efficiency, enabled physicians to focus more on complex patient cases, and made their workload manageable. By employing APPs, 52.3% of physicians were able to increase their patient caseload. The majority (57.6%) of physicians reported that they would employ more APPs in the next 3 years if resources were available, and 41.7% of physicians reported that APPs would likely take on additional responsibility in the next 3 years. Conclusions: Most community oncology practices in the US are employing APPs and are finding significant value in the APP roles by delegating various aspects of patient care to them. Most community practices are considering increasing the number of employed APPs and to expand the breadth of their responsibility. Integrating APPs into oncology practices is likely to have a larger impact on quality of patient care and potential mitigation of physician burnout.
