&Attributable cost to high gabapentin dose in patients hospitalized with altered mental status.

#Low dose as described in this study as ≤600mg per day of gabapentin.

$ Actual proportion of patients in our cohort who were initiated on a high dose gabapentin (>600mg per day)

*100% reduction of patients receiving high dose gabapentin = all patients receive low dose.
