Slide 1: DELIRIUM RELATED FACTORS ASSOCIATED WITH PROGNOSIS FOLLOWING DELIRIUM IN OLDER HOSPITALISED PATIENTS: A SYSTEMATIC REVIEW. A full description follows.

Summary

The systematic review investigates factors associated with prognosis following delirium in older hospitalised patients. It highlights the clinical problem of heterogeneous outcomes despite a shared diagnosis, with approximately 25% of older inpatients experiencing delirium. Key findings indicate that duration and severity of delirium are strongly linked to poorer outcomes, while subtype associations are less clear. The review stresses the importance of ongoing assessment to capture changes over time and recommends careful interpretation of trajectories to inform prognosis, without establishing definitive causation.
