Current guidelines for children are logical. Current guidelines for adolescent/adults follow from an assumption that I am happy to argue against.
All guidelines recommend not to test or treat for Centor scores (with or without McIsaac modification) of 0 or 1. The pre-test probabilities are very low and most positive tests are false positives. Unfortunately, many urgent care centers and emergency departments perform a rapid strep test prior to the treating practitioner spending 3-5 minutes doing a quick history and exam. Testing wastes resources in 40-50% of patients presenting with a sore throat complaint and leads to unnecessary antibiotics. This is the biggest mistake that I see!
The controversy for adolescents/adults with pharyngitis and Centor scores of 2-4 involves the concept of lack of proof. Why treat pharyngitis with antibiotics?
There are 5 potential reasons to treat pharyngitis with antibiotics:
Dr. Michael Fine, professor of medicine at the University of Pittsburgh, led the team that developed the Pneumonia Severity Index (PSI) and began studying the prognosis and other clinical aspects of community-acquired pneumonia (CAP) in the early 1990s.
His interest in predicting mortality in CAP started while he served as chief resident in internal medicine at the University of Pittsburgh. His mentor, Dr. Wishwa Kapoor, then hired him after his general internal medicine fellowship in the Harvard Generalist Faculty Development Program. At the time Dr. Fine transitioned from fellowship to faculty at the University of Pittsburgh, the Agency for Health Care Policy and Research (now the Agency for Healthcare Research and Quality, AHRQ) had a well-funded portfolio of research projects called PORT (Patient Outcome Research Teams) studies.

Editor’s note:Centor’s Corner is a new Paging MDCalc column featuring our favorite pharyngitis guru, blogger extraordinaire, and Scientific Advisory Board member Dr. Robert Centor, with regular insights from Dr. Centor on the applications of evidence to practice and musings from an experienced clinician. To comment on Centor’s Corner articles, please e-mail the editor at firstname.lastname@example.org or tweet directly to Dr. Centor @medrants.
On Twitter recently, several British tweeters discussed whether they should use the FeverPAIN Score or the Centor Score. Obviously I have a bias here, but I will try to discuss this issue dispassionately.
