			----


			=== Ottawa Knee Rule ===
			''Rules out knee fractures to reduce unnecessary radiographs.''

			'''Use in:''' Patients presenting with acute knee injury. '''Note:''' Sensitivity 98.5% for knee fractures.

			{{Ottawa Knee Calculator}}

			----



			== Cardiac / ECG ==

			=== Corrected QT Interval (QTc) ===
			''Calculates corrected QT interval using Bazett's and Fridericia's formulas.''

			'''Use in:''' Patients on QT-prolonging medications, those with [[QT prolongation]], or ECG interpretation. '''Key threshold:''' QTc >500 ms = high risk for Torsades de Pointes.

			{{QTc Calculator}}

			----

			== Gastrointestinal ==

			=== Alvarado Score (MANTRELS) for Appendicitis ===
			''Predicts likelihood of [[appendicitis]] based on clinical and laboratory criteria.''

			'''Use in:''' Patients presenting with RLQ pain or suspected appendicitis. '''Note:''' Score ≥7 is highly suggestive of appendicitis.

			{{Alvarado Calculator}}

			----

			=== Ranson's Criteria for Pancreatitis Severity ===
			''Predicts mortality from [[pancreatitis]] using admission and 48-hour criteria.''

			'''Use in:''' Patients with confirmed acute pancreatitis. '''Note:''' Full score requires 48-hour labs. Cannot be calculated on admission alone.

			{{Ransons Calculator}}

			----

			== Toxicology / Withdrawal ==

			=== CIWA-Ar (Alcohol Withdrawal) ===
			''Quantifies severity of [[alcohol withdrawal]] to guide benzodiazepine therapy.''

			'''Use in:''' Patients with suspected or known alcohol withdrawal. '''Protocol:''' Symptom-triggered dosing: administer benzodiazepines when CIWA ≥10.

			{{CIWA Calculator}}

			----

			== Renal / Electrolytes ==

			=== Anion Gap Calculator ===
			''Calculates the [[anion gap]] with albumin correction and delta-delta ratio.''

			'''Use in:''' Evaluation of metabolic acidosis. '''Mnemonic:''' MUDPILES for elevated AG causes.

			{{Anion Gap Calculator}}

			----

			=== FENa — Fractional Excretion of Sodium ===
			''Calculates [[FENa]] to help differentiate pre-renal vs. intrinsic renal azotemia.''

			'''Use in:''' Patients with oliguria or acute kidney injury. '''Caveat:''' Unreliable on diuretics — use FEUrea instead.

			{{FENa Calculator}}

			----

			== Pediatrics ==

			=== PECARN Pediatric Head CT Decision Rule ===
			''Identifies children at very low risk of clinically-important traumatic brain injury (ciTBI) who do not need CT.''

			'''Use in:''' Children with GCS ≥14 after head trauma. '''Note:''' Two separate algorithms for <2 years and ≥2 years.

			{{PECARN Calculator}}

			----

			== Trauma / Burns ==

			=== Parkland Formula for Burns ===
			''Estimates fluid requirements for burn resuscitation in the first 24 hours.''

			'''Use in:''' Patients with significant thermal burns. '''Key:''' 4 mL × weight (kg) × %TBSA. Give first half in 8 hours from time of burn.

			{{Parkland Calculator}}

			----

			=== Shock Index ===
			''Simple hemodynamic screening tool: Heart Rate ÷ Systolic BP.''

			'''Use in:''' Rapid assessment of hemodynamic compromise in trauma, [[sepsis]], or hemorrhage. '''Normal:''' 0.5–0.7.

			{{Shock Index Calculator}}

			== Cardiac ==

			=== HEART Score for Major Cardiac Events ===
			''Predicts 6-week risk of major adverse cardiac events (MACE) in patients presenting with chest pain.''

			'''Use in:''' Patients ≥21 years old with symptoms suggestive of [[ACS]]. '''Do not use if:''' New ST-elevation ≥1 mm, hypotension, life expectancy <1 year, or noncardiac illness requiring admission.

			{{HEART Score Calculator}}

			----

			=== CHA₂DS₂-VASc Score for Atrial Fibrillation Stroke Risk ===
			''Calculates stroke risk for patients with [[atrial fibrillation]], to guide anticoagulation decisions.''

			'''Use in:''' Patients with nonvalvular atrial fibrillation.

			{{CHA2DS2VASc Calculator}}

			----

			== Pulmonary ==

			=== Wells' Criteria for Pulmonary Embolism ===
			''Objectifies risk of [[pulmonary embolism]] based on clinical criteria.''

			'''Use in:''' Patients with clinical suspicion for PE. '''Note:''' Use clinical judgment first; the Wells score helps quantify pre-test probability.

			{{Wells PE Calculator}}

			----

			=== PERC Rule for Pulmonary Embolism ===
			''Rules out PE if NO criteria are present and pre-test probability is ≤15% (low risk by gestalt).''

			'''Use in:''' Low-risk patients where PE has been considered but is not the leading diagnosis. '''Key point:''' ALL criteria must be negative (No) to rule out PE.

			{{PERC Calculator}}

			----

			=== CURB-65 Score for Pneumonia Severity ===
			''Estimates 30-day mortality of community-acquired [[pneumonia]] (CAP) to help determine inpatient vs. outpatient treatment.''

			'''Use in:''' Adult patients with confirmed or suspected community-acquired pneumonia.

			{{CURB65 Calculator}}

			----

			== Vascular ==

			=== Wells' Criteria for DVT ===
			''Calculates risk of [[DVT]] based on clinical criteria.''

			'''Use in:''' Patients with clinical suspicion for deep venous thrombosis.

			{{Wells DVT Calculator}}

			----

			== Neurological ==

			=== Glasgow Coma Scale (GCS) ===
			''Assesses level of consciousness based on Eye, Verbal, and Motor responses. Score range: 3–15.''

			'''Use in:''' Any patient requiring neurological assessment — trauma, [[stroke]], altered mental status. '''Note:''' GCS should not be used alone for clinical management decisions.

			{{GCS Calculator}}

			----

			== Infectious Disease / Sepsis ==

			=== qSOFA (Quick SOFA) Score for Sepsis ===
			''Identifies high-risk patients for in-hospital mortality with suspected infection outside the ICU.''

			'''Use in:''' Patients with suspected [[sepsis]] outside the ICU. '''Note:''' Per Sepsis-3 definitions, qSOFA ≥2 with suspected infection warrants further evaluation for organ dysfunction.

			{{QSOFA Calculator}}

			----

			=== SIRS Criteria ===
			''Defines the systemic inflammatory response syndrome.''

			'''Use in:''' Screening for SIRS in the setting of suspected infection. '''Note:''' SIRS + suspected infection = [[sepsis]] (per Sepsis-1/2 definitions). Sepsis-3 uses SOFA/qSOFA instead.

			{{SIRS Calculator}}

			----

			== ENT / Pharyngitis ==

			=== Modified Centor (McIsaac) Score for Strep Pharyngitis ===
			''Estimates probability that pharyngitis is streptococcal and suggests management course.''

			'''Use in:''' Patients presenting with sore throat to guide testing and treatment.

			{{Centor Calculator}}

			----

			== Orthopedic / Trauma ==

			=== Ottawa Ankle Rule ===
			''Rules out clinically significant foot and ankle fractures to reduce use of x-ray imaging.''

			'''Use in:''' Patients presenting with ankle or midfoot pain after injury. '''Note:''' Sensitivity 96.4–99.6% for clinically significant fractures. Apply only in adults >18 years.
