Up to 30% of hospitalised medical patients experience incident delirium. Determining risk factors for delirium is important for identifying patients that are most susceptible to incident delirium.DesignRetrospective case-control study with two controls per case.MethodsAn audit tool was used to review medical records of patients admitted to acute medical units for data regarding potential risk factors for delirium. Data was collected between August 2013 and March 2014 at three hospital sites of a healthcare organisation in Melbourne, Australia. Cases were 161 patients admitted to an acute medical ward and diagnosed with incident delirium between 1st January 2012 and 31st December 2013. Controls were 321 patients sampled from the acute medical population admitted within the same time range, stratified for admission location and who did not develop incident delirium during hospitalisation.ResultsIdentified using logistic regression modelling, predisposing risk factors for incident delirium were: dementia, cognitive impairment, functional impairment, previous delirium, and fracture on admission. Precipitating risk factors for incident delirium were: use of an indwelling catheter, adding more than three medications during admission and having an abnormal sodium level during admission.ConclusionsMultiple risk factors for incident delirium exist; patients with a history of delirium, dementia and cognitive impairment are at greatest risk of developing delirium during hospitalisation.Relevance to clinical practiceNurses and other health care professionals should be aware of patients that have one or more risk factors for incident delirium. Knowledge of risk factors for delirium has the potential to increase the recognition and understanding of patients who are vulnerable to delirium. Early recognition and prevention of delirium can contribute to improved patients safety and reduction in harm.
