Risk Assessment & Guidelines Based Care

Consolidates validated anesthesia-relevant risk calculators and patient-specific inputs for perioperative planning. This tool helps clinicians anticipate physiologic risk, procedural complexity, and care considerations before entering the operating room.
Calculators are grouped by system in the order of a typical pre-operative assessment. Switching tabs never clears data.

  1. 1Input patient age, sex, and procedure. No data or PHI is stored.
  2. 2Select a tab in the workflow, then choose a calculator.
  3. 3Complete the inputs.
  4. 4Watch assessment text accumulate results with live updates.
  5. 5Use the copy/paste/print functions for quick reference and insertion to clinical notes.
  6. 6Find patient summary snapshots at the bottom of this page.
ASA Physical Status
Clinical classification of pre-anesthetic physical status.
ASA class
Emergency modifier (E)
Duke Activity Status Index (DASI)

Charlson Comorbidity Index (age-adjusted)
Charlson 1987; weighted comorbidity burden with estimated 10-year survival.
Uses age from the patient header for the age adjustment (+1 per decade from age 50). Select all comorbidities that apply.
Liver disease
Diabetes mellitus
Solid tumor / malignancy
ECOG Performance Status
Eastern Cooperative Oncology Group scale of how a patient's illness affects daily living.
Performance status
Mallampati
Visual airway classification.
Mallampati class Class I: soft palate, uvula, fauces, pillars visible. Class II: soft palate, uvula, fauces visible. Class III: soft palate and base of uvula visible. Class IV: only hard palate visible.

Revised Cardiac Risk Index (RCRI)
Lee 1999; six equally-weighted predictors.
High-risk surgery (suprainguinal vascular, intrathoracic, intraperitoneal)
History of ischemic heart disease
History of congestive heart failure
History of cerebrovascular disease
Insulin-treated diabetes mellitus
Preoperative creatinine > 2.0 mg/dL
Gupta Myocardial Infarction Cardiac Arrest (MICA)
Computed natively from the published Gupta logistic model (Circulation 2011).
Uses age from the patient header and ASA class from the ASA tab, plus the inputs below. Risk of perioperative MI or cardiac arrest within 30 days.
Functional status
Serum creatinine
SORT — Surgical Outcome Risk Tool
Native 30-day mortality model — original SORT (Protopapa et al, BJS 2014). sortsurgery.com also offers SORT v2, which additionally blends a clinician estimate (captured below). Replaces the proprietary NSQIP calculator.
This tool pulls the patient's age from the header and ASA class from the ASA tab. Fill in the items below. It estimates the chance of dying within 30 days of inpatient surgery (it was not built for cardiac or brain surgery). On the SORT website you choose a procedure and it picks the severity for you; here you set the severity yourself.
How major is the operation? Pick the level that best fits the planned procedure. Minor: skin lesion, scope, small biopsy. Intermediate: hernia repair, tonsillectomy. Major: bowel resection, joint replacement. Xmajor / complex: major cancer, aortic, or large abdominal surgery.
How soon is the surgery? Elective: planned in advance. Expedited: needed within days. Urgent: needed within hours. Immediate: life- or limb-saving, right away.
Is this gastrointestinal, thoracic, or vascular surgery? These three specialties carry higher risk in the SORT model.
Does the patient have cancer (active within the last 5 years)?
Optional. Your clinical estimate of the chance of death within 30 days, ideally agreed by the senior perioperative team. SORT v2 (Wong et al, PLOS Med 2020) blends this with the score below, but its exact formula is not published, so this tool just records your estimate next to the objective score.

This number is the objective SORT score only (the published 2014 model). It does not include the clinician's own estimate that SORT v2 adds. Any estimate you pick above is saved in the note next to this score, not mixed into it.

Medication Reconciliation
Paste the active medication list; an organized table is appended to the bottom of the note.

Paste the Patient's Active Medication List.

Spelling Matters. The tool checks each line against an expanded drug dictionary, so a misspelled, abbreviated, or oddly written name may not be recognized.

One Medication Per Line. The tool references an expanded drug dictionary, so a misspelled, abbreviated, or oddly written name may not be recognized. Anything it cannot match is listed under “Unclassified: Manual Review.” Both brand and generic names are accepted.

Everything runs in your browser. No information is recorded or stored. Include:  1) Medication Name, with or without the dose 2) Date of Last Dose Taken.
