After calculating Natalie's modified-Centor Score, what is the next step in her management?

The modified Centor Score is a clinical scoring system used to evaluate the likelihood of a streptococcal throat infection, primarily Group A Streptococcus. Following the calculation of this score, the logic is to either confirm or rule out the presence of this bacterial infection before making treatment decisions.

Ordering a rapid diagnostic test for Group A Streptococcus is a critical next step because it provides a definitive diagnosis. This test helps to determine whether the throat infection is due to streptococcal bacteria, which would then justify prescribing antibiotics. This approach not only allows for appropriate treatment but also helps prevent unnecessary antibiotic use if the test is negative, contributing to better antimicrobial stewardship.

Other management options would not be the most appropriate next steps after determining the modified Centor Score. For example, immediate prescription of antibiotics could lead to unnecessary treatment if the rapid test indicates that the infection is viral rather than bacterial. Similarly, recommending home care without confirming the etiology may delay appropriate treatment if streptococcus is indeed present. Lastly, scheduling a follow-up appointment without first assessing the need for treatment through testing would be inadequate in managing a potentially bacterial infection effectively. Therefore, performing a rapid diagnostic test is the most appropriate and clinically sound next step based on the scenario
