Intermountain Risk Score and Trauma

The Intermountain Risk Score's Association With Mortality Prediction in Trauma Patients

The investigators hypothesize that a risk score composed of age, sex, and the components of commonly ordered laboratory panels will be predictive of mortality in trauma patients, and will help improve clinicians' ability to make more accurate mortality predictions at the time of admission.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years and older (Adult, Older Adult)
• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

• Sampling Method: Non-Probability Sample

Study Population

Individuals who suffer from a traumatic injury and present to the Emergency Department as a Trauma Activation

Description

Inclusion Criteria:

• Patient presents to Intermountain Medical Center as a Level I or Level II trauma activation.
• Age ≥18

Exclusion Criteria:

• Patients who are not admitted to the hospital

  1. Patients who expire in the Emergency Department
  2. Patients who are discharged to home from the Emergency Department
• Patients who do not have a complete blood count and basic metabolic profile drawn in the Emergency Department as part of routine clinical care.
• Patients who enter the hospital as "trauma consults." These patients have traumatic injuries, and are often admitted to the trauma service, but the severity of their trauma is not thought to warrant trauma team activation.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
all cause mortality	To determine whether the Intermountain Risk Score accurately predicts 30 day mortality and one year mortality in trauma patients.	30 days
all cause mortality	measure the ability of the Intermountain Risk Score to predict all cause mortality at one year after the traumatic event	1 year

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
experienced clinicians mortality prediction	compare the IMRS to experienced clinicians' ability to predict mortality at 30 days	30 days
Experienced Clinicians' mortality prediction	compare the IMRS to experienced clinicians' ability to predict mortality at 1 year	1 year
