Patients with chronic kidney disease are at increased risk of medication errors and adverse events due to decreased renal function

slowed drug metabolism and excretion

which puts forward higher requirements for clinicians in drug selection and drug dose determination. At present

clinical decision support system（CDSS） has been widely used to reduce drug errors and improve drug safety

providing a new idea for assisting clinicians to make drug decisions based on patients’ renal function level. This paper aims to review the construction methods

validation

deficiencies and optimization of CDSS based on renal function level

and provide reference for constructing efficient CDSS based on renal function level.
