For patients with uncomplicated sore throat and low risk for rheumatic fever, the main goals are to reduce antibiotic use and provide symptomatic relief. For these patients, an assessment such as the Centor score can be done. Those with a low Centor score (0-2) can be treated with analgesics and there is no need for a POCT.
In patients with a higher Centor score, the consensus gives two choices: They can either be tested (and treated if the testing is positive), or it is reasonable to forgo testing and use a wait-and-see strategy, with reevaluation if they are getting worse after day 3 or not improving after day 5 days of their illness. Illnesses that last longer than 5 days with sore throat and fatigue should prompt consideration of alternative diagnoses, such as infectious mononucleosis.
For patients with potentially complicated sore throat — including indicators such as worsening symptoms after 3 days or worsening after initiation of antibiotics, inability to open the mouth fully, unilateral neck pain or swelling, or rigors — should undergo a careful evaluation. The need for further testing in these patients, including labs and imaging, should be decided on a case-by-case basis. If the patient appears seriously ill, don’t rely solely on POCT for GAS, but think about other diagnoses.
Rheumatic fever. The approach is very different in patients at high risk for rheumatic fever. POCT for GAS is recommended irrespective of their clinical score, and antibiotics should be prescribed if it’s positive for GAS. If a POCT is unavailable, then the consensus recommends prescribing antibiotics for all high-risk patients who have acute sore throat.
This approach is sensible and puts a lot of emphasis on clinical evaluation, though it should be noted that this approach is considerably different from that in the 2012 Infectious Diseases Society of America guidelines.
