Renal impairment and medication use among psychogeriatric inpatients.

Objectives: To determine the prevalence of renal impairment and the dosage appropriateness of several medications for which dosing guidelines in the advent of renal impairment are available.

Method: The authors assessed the renal function and medication use of 37 psychogeriatric patients (mean age of 75 years) living in a psychiatric hospital. Renal function was determined by serum creatinine (SCr) levels and creatinine clearance (CCr) data using the Cockcroft and Gault equation.
