This episode provides a comprehensive overview of the Royal College of Emergency Medicine (RCEM) framework for the training, assessment, and credentialing of Adult Emergency Medicine Advanced Clinical Practitioners (EM-ACPs). The framework establishes a nationally recognised standard of competence, addressing the historical variability in the role, which remains an unprotected title in the UK . A credentialed EM-ACP is a senior clinician integrated into the multidisciplinary team, capable of managing the full spectrum of undifferentiated adult patients, including leading resuscitation and trauma care.
