How this service works
Hardin 2019 SCARF from four caller-assigned flags (incentive spirometry <50% predicted, respiratory rate >20, numeric pain score ≥5, inadequate cough). 1 point each, total 0-4. Proposed threshold is score greater than 2. magent does not measure spirometry or examine the chest. Not a named risk class, analgesia order, or SSRF order.
Output
Returns the integer SCARF score (0–4) summing the four boolean flags, each worth 1 point. A score greater than 2 meets the Hardin 2019 proposed high-risk threshold for surgical respiratory failure. Does not include spirometry measurements, pain assessment, chest examination, or clinical orders.
Example use cases
Postoperative respiratory triage
“I have a patient who just came out of surgery: their spirometry is below 50% predicted, respiratory rate is 22, pain score is 6, but they have an adequate cough — what is their SCARF score and do they exceed the risk threshold?”
Automated clinical documentation
“For our surgical patient record, calculate the Hardin 2019 SCARF score: incentive spirometry is above 50%, respiratory rate is normal, pain score is 3, and cough is adequate.”
Risk stratification workflow
“Flag this ICU patient for pulmonary complication risk using SCARF — they have inadequate cough, respiratory rate over 20, pain score of 8, and spirometry below half of predicted.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/scarfWhen to prefer
Use this endpoint when you have already assessed a postoperative or surgical patient for the four SCARF criteria (spirometry volume, respiratory rate, pain score, cough adequacy) and need to aggregate them into a validated integer risk score. Prefer this over manual summation when building clinical decision-support workflows, automated documentation pipelines, or risk-stratification triggers for respiratory monitoring. This endpoint does not replace clinical assessment — it only performs the arithmetic aggregation and threshold comparison defined by Hardin 2019.
Side effects
- Missing required boolean flags returns a validation error
- Non-boolean input for any flag causes a schema error
- All four flags must be explicitly provided; defaults are not assumed
- Score is caller-dependent — incorrect clinical assessment upstream leads to inaccurate results
