ACUTE & EMERGENCY CARE · WEEKLY EVIDENCE BRIEFING
DKA and delirium: a marker of higher-risk illness
Clinical headline: No new NICE, NHS England or UK specialty-body guidance this week changes emergency management of sepsis, ACS, stroke, anaphylaxis, acute severe asthma, PE, DKA or hyperkalaemia. One large observational DKA study is worth noting, but it does not alter the UK treatment pathway.
What is new?
An analysis of 578,204 adult DKA hospitalisations in the US National Inpatient Sample found coded delirium in 1.1%. Patients with delirium had longer median admission (8 versus 3 days) and higher in-hospital mortality (6.4% versus 3.2%). Delirium was also associated with older age, multimorbidity and complications such as sepsis, stroke, pulmonary embolism, acute myocardial infarction and acute kidney injury.
Practical clinical implication
New confusion in an adult with DKA should be treated as a warning sign, not automatically attributed to acidosis. Reassess ABCDE, glucose and osmolality; review fluid, sodium and potassium trends; and actively consider infection, hypoxia, AKI, stroke, substance withdrawal, medication effects and—where clinically plausible— cerebral oedema. Escalate monitoring and senior review when mental status is abnormal or deteriorating.
Important caveats
This was retrospective US administrative data. Delirium and DKA were identified through coding, timing could not establish causation, and the apparent rise in delirium may partly reflect improved recognition. The findings support vigilance and a search for complications; they do not justify a new drug, investigation bundle or departure from current UK DKA protocols.
