What is a positive Centor score?
In adults, the positive predictive value of the Centor criteria for predicting GAS pharyngitis is around 40% if 3 criteria are met, and about 50% if 4 criteria are met. These criteria along with other clinical features should be used to guide treatment for pharyngitis in adults.
What is modified Centor score?
The Modified Centor Score (also known as the McIssac Score or the McIssac Modification of the Centor Score) helps predict the probability of streptococcal pharyngitis by taking into consideration risk factors such as patient’s age, symptoms, and physical exam.
What is the patient’s score using Centor?
Each of the Centor criteria score 1 point (maximum score of 4). A score of 0, 1 or 2 is thought to be associated with a 3 to 17% likelihood of isolating streptococcus. A score of 3 or 4 is thought to be associated with a 32 to 56% likelihood of isolating streptococcus.
How is Centor criteria calculated?
Centor score estimates the probability that pharyngitis is caused due to streptococcal infection. It is based on Centor criteria (modified/McIsaac) which consist of five simple clinical data….What does the result of Centor score tell you?
| Centor score | Probability of positive culture |
|---|---|
| 3 | 28-35 % |
| 2 | 14-16 % |
| 1 | 5-7 % |
| 0 | 1-3 % |
How accurate is the Centor score?
As a decision rule for considering antibiotic prescribing (score ≥ 3), the Centor score has reasonable specificity (0.82, 95% CI 0.72 to 0.88) and a post-test probability of 12% to 40% based on a prior prevalence of 5% to 20%.
Can you use Centor criteria in children?
The Centor criteria are only validated for adult patients in primary care and are not validated for children under the age of 3 due to the different clinical presentation of GAS in the first years of life.
What does Centor score stand for?
Introduction. Centor criteria (fever >38.5°C, swollen, tender anterior cervical lymph nodes, tonsillar exudate and absence of cough) are an algorithm to assess the probability of group A β haemolytic Streptococcus (GABHS) as the origin of sore throat, developed for adults.
What is the Centor criteria for sore throat?
The Centor Criteria is a four-point scoring system used to assist with risk stratification for GAS pharyngitis and clinical decision making. The four components of the Centor Criteria are: fever, tonsillar exudate, anterior cervical lymphadenopathy, and absence of cough.
How reliable is the Centor score?
Which is better FeverPAIN or Centor?
At a FeverPAIN score of ≥4, the specificity was 98.1%, higher than a Centor score of ≥3 (specificity 86.9%). However, the sensitivity of a FeverPAIN score was very low (3.7%).
What is the McIsaac score?
The McIsaac (modified Centor) scoring system is a validated tool used to determine the likelihood of an acute sore throat being from group A streptococcus (GAS) [ A clinical score to reduce unnecessary antibiotic use in patients with sore throat. CMAJ 1998 Jan 13;158(1):75-83 [FREE Full text] [Medline]1-

What is a modified Centor score?
Centor Score Calculator (Modified/McIsaac) Centor score is the clinical prediction rule that is used to predict the likelihood of strep pharyngitis in the throat which is caused because of a streptococcal infection. Centor criteria consist of five clinical measures which are based on (modified/McIsaac).
What is the mdcalc calculator?
MDCalc loves calculator creators – researchers who, through intelligent and often complex methods, discover tools that describe scientific facts that can then be applied in practice. These are real scientific discoveries about the nature of the human body, which can be invaluable to physicians taking care of patients.
