Inappropriate Antimicrobial Dosing in Regard to Renal Function in a Tertiary Hospital in Greece—A Single-Center Point Prevalence Study

: Inappropriate antimicrobial dosing based on kidney function remains common in hospitalized patients, particularly among older individuals and those with impaired renal function or polypharmacy. Targeted antimicrobial stewardship strategies focusing on renal dose adjustment and agents that are more frequently dosed inappropriately, such as colistin, acyclovir, cefuroxime, and ceftazidime, as well as agents that are frequently prescribed despite a relatively lower rate of inappropriate dose, such as piperacillin/tazobactam, are needed to enhance prescribing safety and optimize therapeutic outcomes.
