[Draft recommendation for preparation of cumulative antibiograms in the Czech Republic].

In today's medicine, one of the main challenges is an extreme increase in bacterial resistance, making antibiotic treatment in both intensive care units and in the community considerably more difficult. To maintain the efficacy of existing antibiotics, close interdisciplinary cooperation is crucial for diagnosing infectious diseases as well as for selecting appropriate antibiotics so that these are only used for treating bacterial infections, not natural bacterial colonization. Antibiotic stewardship has become an ethical imperative, with cumulative antibiograms being one of its core elements. Cumulative antibiograms help with rational choice of antibiotics for initial therapy when the patient's results are still pending. However, preparation of cumulative antibiograms is not clearly defined. Only two American guidelines are available that do not correspond with the needs of clinical microbiology in hospitalized patients. The article aims to present the potential pitfalls of preparing cumulative antibiograms based on the only CLSI guidelines and a draft of recommendation for their preparation in the Czech Republic.
