What strategies are used to select patients for direct admission under acute medicine services? A protocol paper for a systematic review of the literature.

Introduction: Despite unprecedented pressures on urgent and emergency care services, there is no clear consensus on how to provide acute medical care delivery in the UK. These pressures can lead to significant delays in care for patients presenting with emergencies when admitted via traditional routes through the emergency department. Historically, a separate pathway has existed where patients are directly admitted to acute medicine services without attending the emergency department.
