Centor criteria

Centor criteria

(sent′ŏr) [R.M. Centor, contemporary U.S. physician]
A clinical prediction rule used in the diagnosis of streptococcal pharyngitis (strep throat). It includes four elements: fever above 100.5°F (41°C); no cough; exudates on the tonsils; and tenderness in the anterior cervical lymph nodes. The likelihood of strep throat is greater than 40% when all four elements are present. It is less than 3% in patients with just one element. Patients with two or three of the criteria should be evaluated further with rapid antigen tests or throat culture before antibiotics are prescribed.

The Centor Score for Streptococcal Pharyngitis2 (available at https://www.mdcalc.com/centor-score-modified-mcisaac-strep-pharyngitis), also sometimes referred to as the Centor Criteria, estimates the probability that a patient with sore throat has streptococcal pharyngitis, and supports the decision to avoid antibiotics in patients with low scores (and therefore low risk for bacterial infection requiring antibiotics).
According to some studies Centor criteria are the most reliable predictive clinical factors for diagnosis of pharyngitis caused by GABHS.15
Many may be familiar with the clinical scoring algorithm known as the "Centor Criteria."
Most cases are diagnosed clinically, and the Centor criteria are based on clinical evaluation of symptoms and signs.
* to reduce symptoms - there is a modest (approximately one day) reduction in symptoms with early antibiotic treatment and for patients with more severe symptoms it might be two and a half days (severe symptoms [greater than or equal to] 3 Centor criteria) (7)
Upon exam, the patient had 3 Centor Criteria, * and a 10-day course of amoxicillin therapy was initiated.
* Centor Criteria for Strep Pharyngitis: 1 point for each of the following criteria: 1) history of fever, 2) tonsillar exudates, 3) anterior cervical adenopathy, 4) absence of cough.
Because we wished to concentrate on viral pharyngitis, we used the Centor criteria to exclude patients with GABHS pharyngitis.
Standardized clinical decision rules, such as the Centor criteria, can identify patients with low likelihood of group A beta-hemolytic streptococcal (GABHS) pharyngitis who require no further evaluation or antibiotics (strength of recommendation [SOR]: A, based on validated cohort studies).
The CDC / AAFP / ACP recommendations are based on the Centor criteria. (See box.) Two options are offered.
Our study population was made up o f 100 consecutively presenting patients--63 women and 37 men, aged 18 to 64 years (mean: 31.14 [+ or ] 7.93)--who had been diagnosed in our institution's Emergency Department with acute pharyngitis according to Centor criteria. (7) The Centor criteria were developed to estimate the probability of acute GABHS pharyngitis in newly presenting patients.
