This is a pilot evaluation of the APPRAISE trauma decision-support software system ("the System"). The specific objections are as follows:

1. Evaluate the robustness of the System (i.e., whether the software performs in real-time in accordance with a priori technical specifications during real-time clinical use);
2. Evaluate whether the real-time display of the System causes distraction or confusion to clinicians treating the trauma patient such that its risks exceed its benefits;
3. Collect pilot data to allow for a statistical power analysis to design a future clinical trial evaluating efficacy.

Inclusion Criteria:

• Adult (≥18 yrs) Emergency Department (ED) patient
• Triaged to the "Acute" area of the ED. (The "Acute" area is the designated area for ED patients with potential or established critical illness. Triage to Acute is a routine ED operation that is performed based on departmental guidelines and the professional judgement of an experienced triage nurse).
• Clinical concern for acute injury (based on either an explicitly chief complaint of acute injury, or clinical team with documented concern for acute injury as a relevant part of patient presentation).

Exclusion Criteria:

• Prisoners
• Patients known to be pregnant, based on patient report, physical exam, or bedside ultrasound
• Patients wearing an "EFIC Opt-Out" bracelet
• Any concern about the suitability of the software system for a specific patient by any clinician involved in the patient's ED care, or by the patient themselves (or by any LAR [lawfully authorized representative] of the patient).
