Background The global utilization of the physician assistant/associate (PA) is growing. Their increasing presence is in response to the rising demands of demographic changes, new developments in healthcare, and physician shortages. While PAs are present on four continents, the evidence of whether their employment contributes to more efficient healthcare has not been assessed in the aggregate. We undertook a systematic review of the literature on PA cost-effectiveness as compared to physicians. Cost-effectiveness was operationalized as quality, accessibility, and the cost of care. Methods and findings Literature to June 2021 was searched across five biomedical databases and filtered for eligibility. Publications that met the inclusion criteria were categorized by date, country, design, and results by three researchers independently. All studies were screened with the Risk of Bias in Non-randomised Studies—of Interventions (ROBIN-I) tool. The literature search produced 4,855 titles, and after applying criteria, 39 studies met inclusion (34 North America, 4 Europe, 1 Africa). Ten studies had a prospective design, and 29 were retrospective. Four studies were assessed as biased in results reporting. While most studies included a small number of PAs, five studies were national in origin and assessed the employment of a few hundred PAs and their care of thousands of patients. In 34 studies, the PA was employed as a substitute for traditional physician services, and in five studies, the PA was employed in a complementary role. The quality of care delivered by a PA was comparable to a physician’s care in 15 studies, and in 18 studies, the quality of care exceeded that of a physician. In total, 29 studies showed that both labor and resource costs were lower when the PA delivered the care than when the physician delivered the care. Conclusions Most of the studies were of good methodological quality, and the results point in the same direction; PAs delivered the same or better care outcomes as physicians with the same or less cost of care. Sometimes this efficiency was due to their reduced labor cost and sometimes because they were more effective as producers of care and activity.

Physician assistants (PAs) are trained to perform medical procedures that were traditionally performed by medical physicians. Physician assistants seem to be deployed not only to increase efficiency but also to ensure the quality of care. What is not known is the primary motive for employing PAs within Dutch health care and whether the employment of the PAs fulfills the perceived need for them. Supervising medical specialists who used PAs in their practices were interviewed about their primary motives and outcomes. The interviews were semistructured. Two scientists coded the findings with respect to motives and outcomes. In total, 55 specialists were interviewed about their motives for employing a PA, and 15 were interviewed about the outcomes of employing a PA. With respect to the primary motives for employing a PA, the most frequent motive was to increase continuity and quality of care, followed by relieving the specialist's workload, increasing efficiency of care, and substituting for medical residents. The outcomes were found to be consistent with the motives. In conclusion, the primary motive for employing a PA in Dutch health care is to increase continuity and quality of care.

Physician assistants (PAs) are health care professionals who, in some countries, are authorized to practice medicine as part of a team that includes physicians. PAs deliver a broad range of medical and surgical services that are typically performed by physicians. PAs work in hospitals, clinics, and a variety of other health facilities, and exercise autonomy in medical decision‐making as directed by their supervising physician. A period of intense classroom and clinical training precedes the granting of a license to practice as a PA. The profession was created to improve and expand health care. The concept gained acceptance and backing in the United States, as early as the 1970s, as a creative solution to physician shortages. Since then PAs have been increasingly employed and are now found worldwide. Understanding how PAs are utilized is important to international health policy. Several studies in the United States and the Netherlands are currently investigating the efficiency and effectiveness of employing PAs.

BackgroundThe physician assistant (PA) and the nurse practitioner (NP) were introduced into The Netherlands in 2001 and 1997 respectively. By the second decade, national policies had accelerated the acceptance and development of these professions. Since 2015, the PA and NP have full practice authority as independent health professionals. The aim of this research was to gain a better understanding of the tasks and responsibilities that are being shifted from Medical Doctors (MD) to PAs and NPs in hospitals. More specifically in what context and visibility are these tasks undertaken by hospital-based PAs and NPs in patient care. This will enable them to communicate their worth to the hospital management.Study designA descriptive, non-experimental research method design was used to collect and analyze both quantitative and qualitative data about the type of tasks performed by a PA or NP. Fifteen medical departments across four hospitals participated.MethodsThe patient scheduling system and hospital information system were probed to identify and characterize a wide variety of clinical tasks. The array of tasks was further verified by 108 interviews. All tasks were divided into direct and indirect patient care. Once the tasks were cataloged, then MDs and hospital managers graded the PA- or NP-performed tasks and assessed their contributions to the hospital management system.FindingsIn total, 2883 tasks were assessed. Overall, PAs and NPs performed a wide variety of clinical and administrative tasks, which differed across hospitals and medical specialties. Data from interviews and the hospital management systems revealed that over a third of the tasks were not properly registered or attributed to the PA or NP. After correction, it was found that the NP and PA spent more than two thirds of their working time on direct patient care.ConclusionsNPs and PAs performed a wide variety of clinical tasks, and the consistency of these tasks differed per medical specialty. Despite the fact that a large part of the tasks was not visible due to incorrect administration, the interviews with MDs and managers revealed that the use of an NP or PA was considered to have an added value at the quality of care as well to the production for hospital-based medical care in The Netherlands.

Introduction: Shifting specialist care from the hospital to primary care/community care (also called primary care plus) is proposed as one option to reduce the increasing healthcare costs, improve quality of care and accessibility. The aim of this systematic review was to get insight in primary care plus provided by physician assistants or nurse practitioners. Methods: Scientific databases and reference list were searched. Hits were screened on title/abstract and full text. Studies published between 1990–2018 with any study design were included. Risk of bias assessment was performed using QualSyst tool. Results: Search resulted in 5.848 hits, 15 studies were included. Studies investigated nurse practitioners only. Primary care plus was at least equally effective as hospital care (patient-related outcomes). The number of admission/referral rates was significantly reduced in favor of primary care plus. Barriers to implement primary care plus included obtaining equipment, structural funding, direct access to patient-data. Facilitators included multidisciplinary collaboration, medical specialist support, protocols. Conclusions and Discussion: Quality of care within primary care plus delivered by nurse practitioners appears to be guaranteed, at patient-level and professional-level, with better access to healthcare and fewer referrals to hospital. Most studies were of restricted methodological quality. Findings should be interpreted with caution.
