Hospital Costs Associated With Agitation in the Acute Care Setting
Abstract
Objective:
The study determined hospital costs associated with a diagnosis of agitation among patients at 14 general hospitals in Spain.
Methods:
Data from discharge records of adult patients (2008–2012) with a diagnosis of agitation (ICD-9-CM code 293.0) were analyzed. Incremental hospital costs for agitated patients and a control group of patients without agitation were quantified, and the adjusted cost and incremental cost for both groups were compared by use of a recycled-predictions approach.
Results:
The analysis included 355,496 hospital discharges, 5,334 of which were of patients with a diagnosis of agitation. Among patients with a diagnosis of agitation, hospital stays were significantly longer (12 days versus nine days). A significant difference in mean costs of €472 (95% confidence interval [CI]=€351–€593) was noted between patients with agitation and those in the control group. A recycled-predictions approach showed a difference of €1,593(CI=€1,556–€1,631).
Conclusions:
Findings indicate that agitation increased the use of hospital resources by at least 8%.
