Chinese emergency expert consensus on the diagnosis and treatment of sepsis-associated encephalopathy in the elderly

Sepsis-associated encephalopathy (SAE) is a diffuse dysfunction of the nervous system resulting from sepsis originating outside the central nervous system. The elderly (≥65 years of age) are a particularly vulnerable population, and the emergency department is typically the first point of contact following onset of SAE. Clinical symptoms in elderly patients with SAE are often atypical, compounded by a high burden of underlying diseases and complications, which frequently leads to underdiagnosis or misdiagnosis. These patients are at increased risk of long-term or permanent central nervous system impairment, making rapid and accurate diagnosis and treatment especially critical. Currently, there are no standardized diagnostic or treatment guidelines tailored specifically to geriatric SAE. This expert consensus, grounded in evidence-based medicine and clinical experience, offers recommendations on the risk factors, clinical characteristics, diagnosis, and treatment of geriatric SAE. The goal is to standardize care, improve diagnostic accuracy, reduce mortality, and enhance patient outcomes.
