Episodes of delirium were identified using ICD-10 codes and matched 1:1 to non-delirium control episodes within no dementia (n\u00a0=\u200913\u2009004) and dementia (n\u00a0=\u20091790) groups. Matching was performed on age, sex, hospital frailty risk score, primary diagnosis, length of stay and intensive care admission. Incident nursing home admissions were identified from hospital discharge records. Fine\u2013Gray models estimated adjusted subdistribution hazard ratios (SHRs), while accelerated failure-time models quantified time to admission.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Delirium was associated with a higher risk of nursing home admission in participants without dementia (SHR 1.23, 95% CI 1.14\u20131.34) and with pre-existing dementia (SHR 1.22, 95% CI 1.07\u20131.38). Delirium also precipitated admission by ~40% in both groups, corresponding to 1.6\u00a0years earlier (95% CI 1.1\u20131.9) at a survival probability of 0.90 in those without dementia and 1.3\u00a0years earlier (95% CI 0.6\u20131.8) at a survival probability of 0.70 in those with dementia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Hospital-recorded delirium was associated with both if and when older adults entered nursing home care.
