Agreement between renal prescribing references and determination of prescribing appropriateness in hospitalized patients with chronic kidney disease.

Background: Chronic kidney disease (CKD) is a risk factor for adverse drug events. The clinical significance of discordance between renal prescribing references is unknown.

Aim: We determined the prevalence of potentially inappropriate prescribing (PIP) in CKD, measured agreement between two prescribing references, and assessed potential for harm consequent to PIP.
