Predictive modelling of the UK physician associate supply: 2014–2038

This article permits a wider view of potential PA numbers, with broad agreement between the LRM and the TSFM. It appears that future PA demand will be met, but factors such as attrition could impede this. Attrition itself may be mitigated through adequate resourcing, appropriate support mechanisms, and the development of a career structure. Professional regulation and legislation will further support PAs to work to their potential, subject to appropriate patient safety measures.
