First, some definitions:
Clinical pearl: Always ask yourself when a test identifies an organism if that organism seems to be causing disease in the patient or is irrelevant?
Golden Rules of Antibiotic Prescribing:
Ask yourself daily:
An antibiogram is a report that shows how susceptible strains of pathogens are to a variety of antibiotics in a given location.
It can help when creating local clinical protocols (e.g, what is the best treatment for urinary infections in our system) and also to get an idea of how likely the current regimen will be successful while you are waiting for full susceptibilties of an identified organism.
Finally, it can identify antibiotic resistance trends within a geographic area.
An antibiogram is not useful once full susceptibilities come back for a definitive pathogen. In that case, you should use susceptibilities of the pathogen of interest in that particular patient.
An antibiotic is a double-edged sword. With the benefits comes costs:
