[Physician assistants as a future model in primary care: Experiences, needs, potentials and barriers]

In the coming decades, demographic change will dramatically increase health care needs, especially for general practitioners (GPs). However, there is a shortage of young primary care physicians, with signs of (impending) underuse already becoming apparent in rural and structurally weak areas. Innovative care concepts are needed to counteract this development and ensure the future of primary care. In addition to medical assistants (MFA), academically trained physician assistants (PAs) could be considered for more demanding delegation tasks and be involved in direct patient care under the responsibility of a physician in the practice team. In England, the Netherlands and the USA, PAs have been a part of the health care systems for many years.

1) What are the potentials for delegation/possibilities for PAs working in primary care practices in contrast to medical assistants? 2) What structural requirements are necessary to regularly integrate PAs in primary care practices?

After preliminary interviews with PA experts and primary care researchers and practitioners (n=29), four expert interviews (n=4) with GPs and PAs were performed in a case analysis in order to elicit experiences with PAs in family practice. Based on this, three focus groups were conducted with GPs and practice staff (n=15) to discuss the extent, the need and the willingness to delegate physician services to PAs, as well as existing barriers. After transcription, analyses were performed using qualitative content analysis according to Mayring.

The participants acknowledged the potential to reduce physician workloads and showed a high willingness to delegate tasks. Practical examples suggest that a clearly defined delegation of medical tasks to PAs, e.g. participation in infection consultations, is possible after only a few weeks working in family practices. Thus, the cooperation between GPs, PAs and medical assistants can be successful. Uncertainties exist regarding the legal possibilities and limits of delegation as well as the current and future financial reimbursement of PAs.

The legal and financial framework for the utilization of PAs in ambulatory care should be reliably clarified as well as transparently communicated so that the considerable potentials of delegating tasks to academically trained staff, e.g. PAs, especially in the GP sector, can be exploited in the future.

Participation of PAs in the GP team could be key to overcoming the often threatening or already existing under-provision of medical care in structurally weak regions.
