How this service works
Travis 1996 day-3 of intravenous steroids for severe ulcerative colitis. travis_high is true when stools_per_day > 8, or when stools_per_day is 3 to 8 inclusive and crp_mg_l > 45. Stools 8 with CRP 45 is not high. Stools 2 with high CRP is not high. Both parameters are required. Not a colectomy order, not the Ho score, and not Truelove and Witts. magent does not count stools or measure CRP.
Output
Returns a boolean 'travis_high' flag: true if stools_per_day > 8, or if stools_per_day is between 3 and 8 inclusive AND crp_mg_l > 45; false otherwise. Does not produce a colectomy recommendation, a Ho score, or a Truelove and Witts classification.
Example use cases
Day-3 steroid response triage in severe UC
“My patient has severe ulcerative colitis and is on day 3 of IV steroids. They're having 9 stools per day and CRP is 30 mg/L. Can you apply the Travis 1996 criterion to see if they fall into the high-risk category?”
Borderline CRP and stool count classification
“I need to know if a UC patient with 5 stools per day and a CRP of 47 mg/L qualifies as Travis high by the 1996 criterion — can you check that for me?”
Confirming low-risk Travis classification
“For a UC patient on day 3 of IV steroids with 4 stools per day and CRP of 40 mg/L, does the Travis 1996 score classify them as high risk or not?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/travisWhen to prefer
Use this endpoint specifically when you need the Travis 1996 day-3 IV steroid response criterion for severe ulcerative colitis, given stool count and CRP in mg/L. Prefer this over general IBD scoring when the clinical question is precisely whether a patient meets the Travis high-risk threshold on day 3 of intravenous steroids. Do not use for Truelove and Witts classification, Ho score, or colectomy decision support.
Side effects
- Missing required parameter (stools_per_day or crp_mg_l) returns an error
- crp_mg_l provided in mg/dL instead of mg/L yields incorrect classification
- Non-integer stools_per_day rejected by schema
- Values outside valid ranges (stools 0-40, CRP 0-500) may be rejected or produce unexpected results
