Abstract:
OBJECTIVE To analyze the comprehensive intervention measures to raise the etiological submission rate for hospitalized patients before antimicrobial treatment and evaluate the effect.METHODS The hospitalized pa-tients who were treated with therapeutic antibiotics in the Affiliated Hospital of Inner Mongolia Medical University from Jan.2023 to Jun.2023 were assigned as the exploratory analysis phase,the hospitalized patients who were treated with therapeutic antibiotics from Jul.2023 to Dec.2023 were assigned as the first post-intervention phase,and the hospitalized patients who were treated with therapeutic antibiotics from Jan.2024 to Mar.2024 were as-signed as the second post-intervention phase.The related indexes for etiological submission rate before the antimi-crobial treatment were compared before and after the intervention.RESULTS After the comprehensive interven-tion,the etiological submission rate of the entire hospital before the antimicrobial treatment was increased from 28.30％to 42.22％in the first post-intervention phase and 55.86％in the second post-intervention phase.The etio-logical submission rate with respect to diagnosis of hospital-associated infection was increased from 68.34％before the intervention to 85.85％in the first post-intervention phase and 94.58％in the second post-intervention phase.The incidence of hospital-associated infection showed a slight downward trend,dropping from 1.51％to 1.27％in the first post-intervention phase and 1.11％in the second post-intervention phase.The proportion of submission of sterile samples showed a slight upward trend,which was 26.13％before the intervention,29.57％in the first post-intervention phase,28.96％in the second post-intervention phase.There were significant differences in the a-bove indexes(P＜0.05).The etiological submission rate before the combined use of key drugs was increased from 84.71％to 85.95％in the first post-intervention phase and 88.33％in the second post-intervention phase,and there was no significant difference.CONCLUSIONS The etiological submission rate of the hospitalized patients be-fore the antimicrobial treatment is remarkably raised by taking the comprehensive intervention measures,but the etiological submission rate before the combined use of key drugs does not meet the standard,the proportion of submission of the sterile samples is not remarkably raised.It is necessary to continuously complete the intervention measures in the next phase.
