Reducing medication burden and improving pressure injury outcomes in older emergency patients: a pharmacist-nurse collaboration.

Compared with the reference group, patients with pressure injuries exhibited higher Charlson Comorbidity Index, Drug Burden Index, and Medication Regimen Complexity Index scores and poorer clinical outcomes.

Following implementation, the proportion of medication costs and daily Medication Regimen Complexity Index scores decreased significantly (both P < 0.05).

The mean number of prescribed agents decreased by 3.37 and Drug Burden Index declined by 25.30%, though neither reached statistical significance.
