Overview
Nearly 30% of older patients admitted for medical conditions are confused at some point of time during their stay at the hospital.[1] In surgical wards the probability of confusion ranges from 10-50%.[2] Increasing rates are seen in patients admitted to intensive care units and in hospice care. There is no significant difference in the distribution based upon gender or race.
Epidemiology and Demographics
Age
Increasing age is associated with an increased risk of confusion. This in part due to the increased risk of stroke associated with older age as well as an increased risk of metabolic disorders as well as side effects from drugs.
Gender
In general, there is no association of gender with confusion, although a few studies demonstrate an association of male gender with confusion.[3]
Race
Race is not associated with confusion.
