Lau AS, et al. - In this prospective, multi-center observational study, authors developed a predictive score, the Liverpool Peritonsillar abscess Score (LPS) for the presence of peritonsillar abscess (PTA). They added the following 5 significant variables to the logistic regression model: a unilateral sore throat, trismus, male gender, pharyngeal voice change, and uvular deviation. They approved the third iteration of the LPS internally ie, on the same sample, with a sensitivity of 96%; specificity of 85%; positive predictive value of 85% and negative predictive value of 96%. They suggested LPS with high negative predictive value, a helpful tool to non-specialist associates.
