Acute medicine and the urgent care crisis: From pressure point to system solution

Abstract

Acute medicine was established to deliver early specialist assessment and management for patients requiring urgent medical care, typically within the first 72 h of admission. Evidence demonstrates that structured acute medical units (AMUs) and same-day emergency care (SDEC) services are associated with reduced length of stay and improved patient flow. However, inconsistent early access to AMU and suboptimal SDEC utilisation have diluted this model within increasingly pressured urgent and emergency care systems. This article reviews the intended role of acute medicine and examines contemporary challenges in service configuration and delivery. Published evidence and national benchmarking data are considered, alongside a case study describing restoration of a structured AMU model in a large district general hospital. Interventions focused on strengthened clinical leadership, defined admission pathways, multidisciplinary team integration and explicit performance metrics aligned to early discharge. These changes were associated with reduced length of stay, increased direct discharge rates and improved patient flow from the emergency department into AMU. Re-establishing acute medicine's core function offers a practical and scalable approach to improving urgent care performance.
