Predictive Model for the Risk of Delirium in Hospitalized Older Patients

Predictive Model for the Risk of Delirium in Hospitalized Older Patients
[select name="cog" value="no=0|yes=1"] <-- Cognitive impairment (inability to think, concentrate, reason, remember, formulate ideas)
[select name="bun" value="no=0|yes=1"] <-- Elevated blood urea nitrogen/serum creatinine ratio (greater than 18)
[select name="ill" value="no=0|yes=1"] <-- Severe illness (APACHE score greater than 16, or nurse rating of severe)
[select name="eye" value="no=0|yes=1"] <-- Vision impairment (corrected near vision worse than 20/70 in both eyes)

Score --> [calc memo="number" value="score1=(cog)+(bun)+(ill)+(eye)"] points
Interpretation --> [calc memo="result" value="score2=(cog)+(bun)+(ill)+(eye);score2>2?'high risk, 80 percent chance of developing delirium':score2>0?'intermediate risk, 25 percent chance of developing delirium':'low risk, 10 percent chance of developing delirium'"]
