Discharge criteria will vary depending on the clinical scenario and severity of presenting illness, but generally include include lack of fever for 48 hours without antipyretics (excluding steroids), improvement in the presenting clinical symptoms (e.g., diarrhea, rash, etc) and/or improvement in lab markers.

Criteria for discharge should be discussed with services seeing the patient in follow up (e.g., rheumatology, cardiology, and infectious diseases).
Aspirin (ASA)
  • Low-dose ASA should be continued until directed by Cardiology
  • Patients with coronary abnormalities may require prolonged use of ASA
  • Avoid NSAIDS while on ASA
Steroids, if received inpatient
  • 2-3 week oral prednisolone/prednisone taper after initial treatment
  • Suggested taper:
  • 2mg/kg/day div BID x 5 days, 1 mg/kg/day div BID x 5 days, 0.5 mg/kg/day DAILY x 5 days
Outpatient follow-up
  • PCP
    • Follow up within 2-3 days
  • Cardiology
    • Follow up in approximately two weeks. Significant coronary findings or ventricular dysfunction may require earlier follow-up and more frequent echocardiograms. Please see cardiology discharge instructions for additional details.

    • Follow up in 2 weeks.
    • Obtain CBC, CMP, CRP, ferritin, d-dimer, troponin, BNP, fibrinogen prior to appointment

Reasons to return to ED
