Abdominal aortic aneurysm patients remain at risk for delirium on the surgical ward after intensive care unit dismissal.
Abstract
The incidence of delirium following open abdominal aortic aneurysm (AAA) surgery is significant, with incidence rates ranging from 12% to 33%. However, it remains unclear on what level of care a delirium develops in AAA patients. The aim of this study was to investigate the incidence of delirium in the ICU and on the surgical ward after AAA surgery. A single-center retrospective cohort study was conducted that included all patients treated electively for an open AAA repair and patients who underwent emergency treatment for a ruptured AAA between 2013 and 2018. The diagnosis of delirium was verified by a psychiatrist or geriatrician using the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) criteria. The incidence of delirium was calculated. Cox proportional hazards regression analyses were used to analyze 6- and 12-month survival. A total of 135 patients were included, 46 patients (34%) had a delirium during admission. Of these, 30 patients (65%) developed a delirium in the ICU and 16 patients (35%) on the surgical ward. There was no significant difference in six months and twelve months mortality between the ICU and ward delirium groups (HR=1.64, 95% CI: 0.33-8.13, and HR=1.12, 95% CI: 0.28-4.47, respectively).

Aneurysm
Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
Aortic Aneurysm
An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
