Are Physician Associates Less-defined Force Multipliers? Comparative Role Definition of Physician Associates within the Hierarchy of Medical Professionals.

Medical field has changed considerably with pressures added on mainly by soaring costs, a decline in the workforce strength and patient expectations. The solution that healthcare systems have come up with is the induction of physician associates (PAs) into the workforce. We aim to compare and contrast PAs with other members of the healthcare teams such as nurses, doctors and assistant physicians to demonstrate the vital role PAs play in the current healthcare environment. With the increased patient load and shrinking medical workforce, there are fears that chronic disease management in primary and secondary care will be threatened. Therefore, health policymakers thought of developing a new mid-level practitioner role (such as PAs, ANPs and APs) that will augment physicians to cater for ever-growing complex medical needs of the patients. The role of PAs is comparable to many healthcare professionals, and one can say that the success of PA programmes has paved the way for the development of different other mid-level practitioner development initiatives. All these roles are there to support primary and secondary care physicians in both inpatient and outpatient settings in helping the patients. PAs are a force multiplier within the healthcare sector and can be seen as a valid solution to staff shortages faced by the healthcare systems around the world. We recommend further studies looking into different aspects of the role of a PA that could further provide our readers with clarity with regard to PAs.
