- Bayesian calculatorAortic DissectionCompare the patient with a published atraumatic-chest-pain baseline, then apply dedicated clinical findings and optional CXR/D-dimer results.
- Calcium Correction for AlbuminAssess whether an abnormal total calcium may be explained by hypo- or hyperalbuminemia.
- Canadian CT Head Rule (CCHR)Use during the initial assessment of blunt head trauma within 24 hours in patients age ≥16 with initial GCS 13–15 and witnessed loss of consciousness, definite amnesia, or witnessed disorientation. Do not use when trauma was secondary to another primary event, such as seizure or syncope.
- CIWA-ArAssess current alcohol-withdrawal symptom severity after alcohol withdrawal has been clinically identified.
- Bayesian calculatorEctopic PregnancyCompare the patient with a published symptomatic first-trimester ED baseline, then apply the available examination and ultrasound findings.
- Glasgow-Blatchford Score (GBS)Estimate need for hospital-based intervention in suspected upper GI bleeding.
- Modified Centor / McIsaac Score (MCS)Risk stratification for suspected group A streptococcal pharyngitis using age-adjusted Modified Centor criteria.
- Bayesian calculatorNecrotizing Soft Tissue Infection (NSTI)Bayesian decision support for adults admitted through the ED with severe extremity soft-tissue infection, combining a baseline-anchored prior, complete LRINEC laboratory score, and optional imaging.
- Nephro - Cockcroft Gault (CrCl)Estimate creatinine clearance using the Cockcroft-Gault equation from age, sex, weight, and serum creatinine.
- Bayesian calculatorNeuro - Ottawa Subarachnoid Hemorrhage (SAH)Bayesian SAH risk calculator with prior, modifiers, symptom/sign tri-state inputs, Ottawa parallel rule status, and optional CT update handling.
- Bayesian calculatorPediatric Appendicitis — Bayesian Decision Aid + AlvaradoA Bayesian decision aid for pediatric appendicitis that combines clinical findings, laboratory results, and ultrasound findings to estimate residual risk and support imaging decisions.
- PERC (Pulmonary Embolism Rule-out Criteria)Rule out pulmonary embolism in appropriately selected patients with low pretest probability.
- Pulmonary Embolism Severity Index (PESI)Traditional, point-based risk stratification for PE. Inputs use Yes/No flags (age in years). Outputs include total score, class, mortality reference, and guidance.
- Sodium Correction for HyperglycemiaCompare conventional and Hillier corrected-sodium estimates in hyperglycemia.
- Bayesian calculatorSpinal Epidural Abscess (SEA)Update spinal epidural abscess risk using clinical risk factors and optional ESR or CRP.
- Wells Score for Pulmonary EmbolismEstimate pulmonary embolism pretest probability using the seven-item Wells rule.
