Advanced Clinical Practitioners in the ED

This study is designed to understand better how nurses, paramedics, and other healthcare professionals who have completed extra training to become Emergency Care Advanced Clinical Practitioners (EC-ACPs) work in emergency departments (EDs). The research questions are: 1\) What is the EC-ACP's perception of assimilation into emergency care teams, what tensions are created due to the role, and what system adaptations are required to facilitate integration? With secondary aims : 1. What are the common organisational factors that affect the implementation of the EC-ACP workforce, and what recommendations can be made to improve Trust-wide implementation? 2. How are EC-ACPs deployed in two contrasting emergency departments, what differences can be identified in their Work-As-Done (WAD), and how does this compare to the Work-As-Imagined (WAI) of the role? No patient data is being collected; the participants will all be hospital staff: 1. EC-ACP participants will be observed in practice, interviewed, or both. 2. Staff who are not EC-ACPs but work with them will be interviewed for their thoughts on how they work together.
