Abstract
This retrospective cohort study sought to derive and validate a home scoring system based on established clinical scoring systems to help adult patients > 15 years of age determine whether to seek urgent or emergent care for a chief complaint of sore throat, with the goal to prevent urgent and emergent visits for patients that would not likely require testing or therapy directed at streptococcal pharyngitis. The variables used to generate a patient’s home score were based on those from the established Centor, McIsaac, and Clinical Biosurveillance scores, with clinician-generated variables removed (like tender anterior cervical lymphadenopathy and tonsillar exudates) and addition of a biosurveillance variable known as the recent local proportion positive (RLPP), which point estimates a 2-week prevalence of positive rapid strep amongst all those who were tested in a geographic region.
