- Centor / McIsaac Score for Strep PharyngitisPredicts likelihood of Group A Streptococcal (GAS) pharyngitis to guide antibiotic prescribing. McIsaac modification adds age adjustment.
- Lund-Mackay CT Score for Chronic RhinosinusitisRadiological staging system for chronic rhinosinusitis using CT sinus scoring. Each sinus scored 0-2. Maximum score 24.
- EpiScore for Epistaxis SeverityClinical scoring system for acute epistaxis to guide treatment escalation from simple first aid to intervention.
- Paradise Criteria for TonsillectomyEvidence-based criteria for tonsillectomy in recurrent tonsillitis. Requires ≥7 episodes in 1 year, ≥5/year for 2 years, or ≥3/year for 3 years.
- Dix-Hallpike Test Interpretation / BPPV AssessmentClinical assessment and diagnostic criteria for Benign Paroxysmal Positional Vertigo (BPPV) based on Dix-Hallpike findings.
- Snellen Visual Acuity InterpretationInterprets Snellen chart visual acuity measurements. Standard notation: 6/x metres (UK) or 20/x feet (US). Used to screen for visual impairment, assess driving eligibility, and guide referral to ophthalmology.
- Ishihara Colour Vision Test InterpretationPseudoisochromatic plate test for identifying congenital red-green colour vision deficiency. Standard 24-plate test: 17+ correct = normal; 13 or fewer = colour vision deficiency. Important for certain occupations (aviation, driving, certain clinical roles).
- Acute Rhinosinusitis Severity (EPOS Criteria)Classifies acute rhinosinusitis severity and guides antibiotic prescribing based on EPOS 2020 guidelines.
- SNOT-22 (Sinonasal Outcome Test)Patient-reported outcome measure for chronic rhinosinusitis. Score 0-110; higher scores indicate greater disease burden. Guides treatment decisions and surgical referral.
- Hearing Loss Grading (WHO Classification)Grades severity of hearing loss based on average hearing threshold (dB HL) per WHO classification. Guides audiological and surgical referral.
- FeverPAIN Score (Streptococcal Tonsillitis)Predicts likelihood of Group A streptococcal pharyngitis/tonsillitis to guide antibiotic prescribing. Developed in UK primary care.
- STOP-BANG Score (Obstructive Sleep Apnoea)Screens for obstructive sleep apnoea (OSA) using 8 dichotomous questions. High risk guides polysomnography referral and perioperative planning.
- Epistaxis Severity Score (ESS)Quantifies epistaxis severity to guide management from first aid to surgical intervention. Considers frequency, volume, and haemodynamic impact.
- HINTS Plus (Central vs Peripheral Vertigo)Differentiates central (stroke) from peripheral vertigo using Head Impulse, Nystagmus, Test of Skew (HINTS) plus hearing loss. Outperforms early MRI for posterior fossa stroke.
- Acute Otitis Media Severity (AOM-SOS)Grades acute otitis media severity to guide antibiotic prescribing vs watchful waiting in children and adults.
