[Physician Assistants - Eine effektive und sinnvolle Erweiterung des herzchirurgischen Behandlungsteams].

High-quality care of cardiac surgical patients requires the employment and recruiting of qualified medical professionals with minimal fluctuation of staff members. This aspect becomes increasingly difficult due to the current shortage of skilled professionals as well as the present framework conditions of the German Healthcare System. The implementation of physician assistants (PA) in cardiac surgery departments may augment existing human resource concepts in an innovative and sustainable manner, tailored to meet department specific requirements. Long-term experiences from Anglo-American countries prove that the implementation of a PA system may stabilize or potentially even improve medical treatment quality. At the same time, cardiac surgical residents may be relieved from routine tasks, releasing additional time resources for a solid and diverse specialist training. Furthermore, positive effects on economic aspects of an institution may be possible. The required delegation of medical tasks to allied health professionals already has a legal basis in Germany, while a specific legal framework tailored to physician assistants does not exist yet. In this context, it is an important aspect that medical associations define a reliable catalog of tasks that may be delegated to physician assistants. Under evaluation of medical, legal and economic aspects and in a structured manner, this position paper defines medical tasks of physician assistants in cardiac surgery.
