Longevity & AgingHospital delirium signals years of added risk for falls, sepsis, stroke and more
Delirium, a sudden state of confusion during a hospital stay, is common in older adults. Little is known about what follows beyond cognitive decline, functional loss and death. Using UK Biobank data linked to hospital records, researchers matched 14,909 people who had delirium to hospitalised people without it, based on age, sex, frailty score, diagnosis and length of stay. Over up to 26 years of follow-up, delirium was linked to higher risk of 12 of 15 adverse outcomes in later hospital stays. These included urinary incontinence (about double the risk), falls, pressure injuries, kidney injury, sepsis, hip fracture and stroke. Each additional delirium episode raised risk by 6-17%. Results held after excluding people with dementia. The authors suggest delirium may be a warning sign of broader, long-term vulnerability, though an observational design cannot prove cause.
