Creatinine Clearance (Cockcroft-Gault)
The equation the DOAC trials dosed by, with dose-adjustment guidance for all four agents.
The general-medicine bench
Clinical calculators.
General-medicine calculators with the interpretation layer built in. Every tool pairs the score with the decision it feeds — the threshold, the trial behind it, and where it touches neurovascular practice — and is reviewed by Zaka Ahmed, MD. Stroke-specific scores live under Clinical Tools.
Educational use only
These calculators support learning and bedside discussion. They do not replace clinical judgment, institutional protocols, or emergency care.
§ 01 · Renal, hepatic & dosing
The numbers doses are built on.
Child-Pugh Score
Cirrhosis classes A–C, with the anticoagulation-in-liver-disease panel.
Phenytoin Correction (Sheiner-Tozer)
Albumin- and renal-corrected levels, and when to just order the free level.
Sodium Correction for Hyperglycemia
Katz and Hillier factors side by side.
§ 02 · VTE & thrombosis
Clot risk, sized honestly.
Wells Score — Pulmonary Embolism
Two-tier and three-tier, with the d-dimer strategy.
Wells Score — DVT
Ten items, the −2 alternative-diagnosis item included.
Khorana Score
Chemotherapy VTE risk and the AVERT/CASSINI prophylaxis threshold.
Antiphospholipid Syndrome Criteria
Sydney criteria with the young-stroke and warfarin-not-DOAC context.
§ 03 · Cardiopulmonary & critical care
Severity at the bedside.
HEART Score
Chest-pain MACE risk with disposition bands.
qSOFA
The bedside sepsis flag, with the honest 2021-guideline caveats.
CURB-65
Pneumonia severity, with the aspiration-after-stroke frame.
MAP & Maintenance Fluids
The number CPP targets are built from, plus Holliday-Segar 4-2-1.
§ 04 · Screening & assessment
The questions worth asking.
PHQ-9
Depression screening with the post-stroke lens and item-9 safety handling.
GAD-7
Anxiety screening, fear-of-recurrence included.
CAGE Questionnaire
Alcohol screening and the day-two withdrawal trap.
Canadian CT Head Rule
Minor head injury imaging, with the anticoagulation exclusion up front.
§ 05 · Neurology-adjacent
Where medicine meets the brain.
SeLECT 2.0
Post-stroke epilepsy risk, and why it changes counseling rather than prescriptions.
Duke-ISCVID Criteria
Endocarditis classification; the stroke that is a minor criterion.
EDSS
The MS disability scale, with the mRS comparison stroke readers want.
Pediatric NIHSS
The validated 2–18 adaptation, scored with the task modifications inline.
§ 06 · General
The everyday numbers.
BMI & Body Surface Area
With the places each number actually matters.
Due Date & Gestational Age
Because pregnancy timing is neurologic triage context.
