How this service works
Nemeth 2020 TRiP(cast) VTE risk after lower-limb trauma immobilization. Caller-assigned Table 1 trauma (high 3, intermediate 2, low 1) and immobilization (upper_leg 3, lower_leg 2, foot_cast 1, other_plantar 0) plus age, sex, BMI, and nine flags. Max 34. High-risk at score >=7. Not a diagnosis or thromboprophylaxis order. magent does not classify the radiograph.
Output
Returns the TRiP(cast) total score (integer 0–34) computed from all supplied parameters, a boolean or flag indicating high VTE risk (score ≥7), and optionally component subscores for trauma, immobilization, age, sex, BMI, and each clinical risk flag. Does not produce a diagnosis or thromboprophylaxis order.
Example use cases
Post-fracture DVT risk stratification
“I have a 72-year-old female patient, BMI 32, with a bi-malleolar ankle fracture — intermediate trauma — immobilized in a lower-leg cast. She has chronic venous insufficiency and a family history of VTE, but no personal history, no cancer, not pregnant, no recent surgery, no hormonal therapy, and no other comorbidities. What does her TRiP(cast) score come out to and is she high risk?”
Pre-discharge thromboprophylaxis review
“Before discharging my 45-year-old male patient (BMI 24) who had a grade-3 ankle sprain — low trauma — and is in a plantar cast, I need his TRiP(cast) score. He had surgery 6 weeks ago, no VTE history, no cancer, no hormonal meds, no comorbidities, and no chronic venous insufficiency.”
Outpatient orthopedic clinic triage
“Can you calculate the Nemeth TRiP cast VTE score for a 38-year-old female, BMI 38, with a patellar fracture — intermediate trauma — in an upper-leg cast? She's currently pregnant, no personal or family VTE history, no cancer, no other immobilization, no recent surgery, and no comorbidities or chronic venous insufficiency.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/trip_castWhen to prefer
Use this endpoint when you need to implement the specific Nemeth 2020 TRiP(cast) validated clinical decision-support score for VTE risk in patients with lower-limb trauma or cast immobilization. Prefer it over generic DVT risk tools (e.g., Wells score) when the clinical context is specifically lower-limb orthopedic injury or cast immobilization. The caller must pre-assign trauma category and immobilization type; this endpoint does not interpret imaging.
Side effects
- Missing required query parameters returns a 400 error
- Invalid enum values for trauma (not high/intermediate/low) or sex (not female/male) return a validation error
- BMI outside the 10–80 range may be rejected or produce unexpected output
- Age outside 1–120 may be rejected
- Boolean flags passed as strings instead of true/false may cause parsing errors
- Caller incorrectly assigns trauma category (magent does not classify radiographs) leading to incorrect scores
