Delirium is commonly associated with acute illness, causes distress and leads to poor outcomes. However, little is known about delirium presentations in OOH services. We aimed to investigate using records from an OOH service in South-West England.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The database contained 33\u2009345 contacts with patients \u226565\u00a0years attending the OOH service. We screened consultations during April and July 2019, and January 2020 using an automated search then clinical review by two independent GPs. We validated our search strategy by reviewing a random sample of 100 \u2018search-negative\u2019 consultations initially and assessed inter-rater reliability. Patient characteristics were compared using Chi-squared tests.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of 4288 consultations with patients \u226565\u00a0years in the study periods, 402 (9.4%) involved possible or probable delirium. A further 74 (1.7%) had end-of-life delirium and were excluded from further analysis. Patients with delirium were older (mean age 84.4\u00a0years vs. 80.1\u00a0years), and more often had dementia (46.6% vs. 10.4%, P\u00a0&amp;lt;\u2009.001). 67.9% of delirious patients required home visits, compared to 22.2% without delirium (P\u00a0&amp;lt;\u2009.001). Patients with delirium were admitted to hospital twice as often as those without (20.6% vs. 8.5%, P\u00a0&amp;lt;\u2009.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Delirium is a common OOH presentation, representing ~10% of consultations with patients \u226565\u00a0years. These patients often have cognitive impairment, require home visits and are more likely to be admitted to hospital.
