LJJ CSTR STUDY GUIDE WITH QUESTIONS AND
CORRECT ANSWERS 2024
An elderly patient fell while out of state, went to an ER where he received a knee immobilizer for a
fractured R patella. Upon arriving back home he presents to your ED where he's admitted for pain
control and placement by Case Management. Does he get included in the trauma registry? - -
No, since he was seen and treated at another hospital; he wasn't seen by Trauma, and he wasn't
treated for the fracture.
A 15 y.o. presents to the ED with a GSW and dies within 15 mins. of arrival. Should he be included in
the trauma registry? - -Yes, since he had a traumatic mechanism of injury.
A patient presented to the ED after a fall resulting in a R radius/ulna FX. He was splinted and
discharged. He returned 2 days later for an ORIF. Does this meet criteria to be included in the
registry? - -No, since this was a planned readmission.
A 24 y.o. MVC presents to the ED with a forehead and large wrist laceration w/ tendon involvement.
He went to the OR for repairs and was discharged. Does he qualify for the registry? - -Yes
A patient comes to the ED complaining of leg pain w/o history of fall or trauma. The patient has a Hx
of osteoporosis and bone cancer. Imaging shows a femur fracture; the patient was admitted. Does
he qualify for the registry? - -No, the injury was a-traumatic
The inclusion or exclusion criteria used to select patients for entry into the trauma registry can vary
from hospital to hospital, T or F? - -True: each trauma facility has their own set of trauma
inclusion criteria.
, What is the ISS for a patient with an AIS of 6? - -75: If an injury is assigned an AIS of 6 (usually
an unsurvivable injury), the ISS score is automatically assigned to 75. The ISS score is virtually the
only anatomical scoring system in use and correlates linearly with mortality, morbidity, hospital
stay and other measures of severity
The Revised Trauma Score (RTS) includes - -RR, SBP and GCS; a perfect score is 7.84
How is the Trauma & Injury Severity Score (TRISS) (also referred to as Probability of Survival)
calculated? - -Age, RTS, MOI (B or P injury), ISS
Best graph for representing M v. F injured by age groups 0-15, 16-25, 26-54, 55 and older - -A
histogram has connected bars that display frequency of cases falling within defined intervals or
columns
Best graph for representing LOS continuous over time - -A line graph displays the relationship
between 2 types of information such as LOS by month; it shows trends over time.
Best graph for representing LOS by ISS Score - -Scatter plots display values for 2 variables w/
one variable on the horizontal axis and the value of the other variable on the verticle axis.
Best graph for representing Percent of patients who arrive from the scene vs. OSH - -Pie chart
