Empirical antimicrobial therapy of purulent-septic complications in surgical coloproctology

Abstract

Object. to optimize antibacterial therapy in patients with coloproctological profile with purulent-septic complications.Materials and methods. A one-center intervention study with historical control was conducted. The intervention began in January 2017, when in the hospital FSBI «N. I. Pirogov National Medical Surgical Center» Russian Ministry of Health introduced strict monitoring of compliance with the protocols of empirical antimicrobial therapy. The study included 62 patients who underwent antibacterial therapy after operations on the colon and rectum in 2016–2017. Patients were divided into two groups with respect to the beginning of the intervention: 2016 – comparison group (A), 2017 – main group (B).Results. There was a slight decrease in the total consumption of antibacterial drugs in coloproctological patients from 823.0 to 691.0 Defined Daily Dose (DDD, established daily dose), as well as the average consumption of antibiotics per patient from 26.5 to 22.3 DDD. An increase in the number of cases of compliance with the approved protocol of empirical antimicrobial therapy (AMT) was revealed from 32.3 % in group A to 67.7 % in group B, p = 0.01. The frequency of adequate empirical antibiotic prescribing increased from 71.0 to 93.5 %, p = 0.042. A significant increase in the frequency of de-escalation of AMT was revealed from 3.2 % in group A to 25.8 % in group B, p = 0.026.Conclusion. Monitoring compliance with empirical AMT protocols allowed to increase the number of cases of adherence to approved protocols, which positively affected the frequency of adequate appointment of empirical AMT, and also led to increase the number of cases of de-escalation of AMT.
