Abstract
Introduction: GAS pharyngitis is both antecedent for invasive streptococcal infection and post infectious immunologic complication of Rheumatic fever/RHD, a leading cause of cardiovascular morbidity and mortality in many developing parts of the world.
Aims and Objective: To analyse the usefulness of symptoms and signs in assessing the risk of streptococal pharygitis and to correlate McISSAC score with throat swab culture.
Results: About 50% of patient tested positive for GABHS have Mc-Issac score of 5, whereas 25% of positive tested patient have score of 4 and again 25% of positive patient have score of 3. The chi-square test of association is significant. Therefore, 75% of positive GABHS findings have Mc-Issac score of 4 and 5.
Conclusion: Individual signs and symptoms are not powerful enough to discriminate GABHS pharyngitis from other types of sore throat. The McIsaac score is well calibrated clinical prediction rule for estimating the probability of GABHS pharyngitis. The result of McIsaac score and culture finding of GABHS have close association with each our.
Keywords: McIsaac score, GABHS, Throat swab culture and sensitivity.
