OBJECTIVE： To introduce Beers scale （2015 edition） for potentially inappropriate medication （PIM） evaluation in elderly patients， in order to update Beers criteria in China and provide reference for the formulation， implementation and application of rational drug use standard for elderly patients in China. METHODS： Beers criteria （2015 edition） issued by American Geriatrics Society （AGS） was compared with Beers criteria （2012 edition） in respects of formulation method， catalog and items. RESULTS： Like Beers criteria （2012 edition）， Delphi method was used to formulate Beers criteria （2015 edition）. Two catalogs were added： drug-drug interaction catalog which elderly patients should avoid， and renal function-based reduction/avoidance catalog. Some controversial drugs were excluded from previous 3 catalogs， and other drugs which elderly patients should avoid were included.  CONCLUSIONS： With the absence of PIM golden criteria for elderly patients， Beers scale is still a powerful tool to ensure the rational drug use in elderly patients. Whether it is suitable for elderly patients in China， it should be based on the doctor’s prescription habits and the specific circumstances of the patients.
