[Sore Throat - Guideline-based Diagnostics and Therapy].

Abstract

Background: Sore throat is a common reason for consultation of family physicians. Acute sore throat (< 14 days) is usually triggered by infections of the pharynx. Less than 35 % of cases are caused by bacterial infections; nevertheless, antibiotics are prescribed far more often. Evidence-based guideline recommendations are available to reduce non-indicated administration of antibiotics in the treatment of sore throat.

Search methods: Update of the clinical guideline "sore throat" of the German College of General Practitioners and Family Physicians (DEGAM) by means of a systematic search of the literature for international guidelines and systematic reviews.

Main messages: After excluding red flags such as immunosuppression and severe systemic infections, acute sore throat is usually self-limiting with a mean duration of 7 days. Patients should be encouraged in self-management; ibuprofen and naproxen are recommended for symptomatic treatment. If antibiotics are considered, clinical scores (Centor, McIsaac, FeverPAIN) should be used to assess the risk of bacterial pharyngitis. At low risk (< 3 points), antibiotics are not indicated; if at least moderate (3 points), delayed prescription is an option; if high (> 3 points), antibiotics can be taken immediately. Even if scores suggestive a bacterial cause, the evidence suggests that antibiotic treatment only shortens the duration of symptoms modestly. Penicillin is the first choice (clarithromycin as an alternative). The antibiotic should be taken for 5-7 days.

Conclusions: In the absence of red flags, a regular use of symptomatic treatment will help to control discomfort. If administration of antibiotics is still considered a risk-adapted approach, using clinical scores is recommended.
