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).
Why did you develop the Centor Score? Was there a clinical experience that inspired you to create this tool for clinicians?
What pearls, pitfalls and/or tips do you have for users of the Centor Score? Are there cases when it has been applied, interpreted, or used inappropriately?
What recommendations do you have for health care providers once they have the Centor Score result?
Consultation rates for sore throat diminished in the l990s (14), and the 2008 UK national guidelines advise against diagnostic testing and recommend a policy of nonprescribing or delayed prescribing for sore throat when the Centor score
is <3 (3).
AbstractObjective: To study the prevalence of Group A beta haemolytic Streptococcus in patients with acute pharyngitis and correlation of Modified Centor Score and Rapid Antigen Detection Test.
They were scored using Modified Centor Score and were tested with Rapid Antigen Detection Test for Group A beta haemolytic Streptococcus.
Modified Centor Score had a strong positive correlation with Rapid Antigen Detection Test in identifying Group A beta haemolytic Streptococcus as a cause of acute pharyngitis.Keywords: Acute pharyngitis Group A beta haemolytic Streptococcus Rapid Antigen Detection Test (RADT) Modified Centor Score.
The original Centor score uses four signs and symptoms to estimate the probability of acute streptococcal pharyngitis in adults with a sore throat.4 The score was later modified by adding age and validated in 600 adults and children.56 The cumulative score determines the likelihood of streptococcal pharyngitis.
The Modified Centor Score (MCS) is a valid tool to estimate the probability of acute streptococcal pharyngitis in patients with a sore throat.
Clinical prediction rules can help Useful and well-validated clinical prediction rules (such as the Centor score) can help you make more informed decisions about testing.
(4) The American College of Physicians state that a positive confirmatory laboratory test or Centor score of 4 could reasonably warrant treatment.
