Abstract

Analysis of data from Sore Throat in Primary Care Project provided a scoring system, called the MistikScore, to diagnose viral sore throat. The predictive model for positive viral analysis included the following variables: absence of headache, stuffy nose, sneezing, temperature of ≥37.5°C on physical examination, and the absence of tonsillar exudate and/or swelling. The probability of a positive viral analysis for a score of 5 was 82.1%.

Modified Centor-GAS Diagnosis	Score	Mistik Score-Viral Infection Diagnosis	Score
Absence of cough	1	Absence of headache	1
Anterior cervical nodes	1	Stuffy nose	1
Over 38°C body temperature	1	Sneezing	1
Tonsillar exudate and/or swelling	1	≥37.5°C body temperature	1
3-14 Years	1	Absence of Tonsillar exudate and/or swelling	1
15-44 Years	0
45 Years and over	-1

Modified Centor Score-Suggestion of use

0 and less score-no need for further test or antibiotics
1-3 score-throat culture or rapid antigen test, antibiotics for positive test
4 and over-empirical antibiotic use
