Antibiotics are commonly prescribed by junior doctors but knowing which one to use in different clinical conditions can be confusing.

You can download many Trust/Health Board's antibiotic policies as an app called RxGuidelines onto your phone (find it in your app store and select your Trust/Health Board), this is incredibly useful when prescribing.

To choose antibiotics rationally, you need to answer three questions about your patient:

What is the likely source of infection?

(Clinical assessment)

Which pathogens are likely to cause infection at that site?

(Bugs - knowledge of basic clinical microbiology)​

Which antibiotics are likely to cover those pathogens?

(Drugs - knowledge of antibiotic spectra)

You are already well-versed in clinical assessment. The resources page features Bugs and Drugs sections, lecture slides, national guidance documents, games such as Antibiotic Top Trumps and Bug Bingo and a list of useful external resources.
