Same day emergency care (SDEC) is the provision of patient care with an investigation and/or treatment within the same day for non-elective patients who in the past would otherwise be admitted to a hospital bed.


This new Health Building Note (HBN) gives guidance on the planning and design of an SDEC department. A well-designed SDEC unit will help to manage patients effectively with minimal delays as they move through stages of care. Good patient flow is central to patient experience, clinical safety and reducing the pressure on staff. It is a key factor in providing effective healthcare.
