ABSTRACT
Objective To promote the rational antibacterial drug use for common digestive system (DS) diseases by reviewing the clinical application of antibacterial drugs for hospitalized patients, formulating the hospital clinical specification of antibacterial drugs for common DS diseases and establishing the clinical application of antibacterial drug differentiation index for DS department.Methods 300 cases were selected from 2 060 hospitalized DS patients in the year 2014 based on the given disease ratio.The usage rate and intensity of antibiotics were calculated with survey and medical statistical analysis.The differentiation index for the clinical application of antibacterial drugs were established.Results Theoretical values of usage rate and use intensity of antibiotics in DS department were 29.0%, 41.5 DDDs according to analysis.However, the practical values were 40.3%, 50.3 DDDs.Conclusion It is necessary to improve the level of clinical antibacterial drug use.One effective way to achieve such goal is to establish the differentiation index of antibacterial drug clinical application for the department.
