Experimental: Eligible low-risk trauma patients
Paramedics will use the Canadian C-Spine Rule to evaluate low-risk trauma patients meeting the study inclusion criteria in order to determine the need for spinal immobilization for transport to the hospital.
Procedure: Canadian C-Spine Rule
Paramedics will apply a validated decision rule (the Canadian C-spine Rule) to determine whether or not immobilization is required for trauma patients being transported to the emergency department.
- Adverse Events [ Time Frame: within 30 days of enrollment ]
Measures of safety will include:
- number of missed cervical spine injuries
- number of serious adverse outcomes
- Clearance Rate [ Time Frame: Measures of clinical impact will be assessed immediately following the patient's Emergency Department visit ]Proportion of eligible low-risk patients transported without immobilization
- Performance of the Canadian C-Spine Rule [ Time Frame: Rule accuracy will be within 30 days of enrollment. Paramedic accuracy of interpretation and agreement will be assessed immediately following enrollment. ]
Measurements of the performance of the rule will include:
- rule accuracy
- paramedic accuracy of interpretation
- paramedic agreement and level of comfort with the decision suggested by the Canadian C-Spine Rule
- Scene Time [ Time Frame: immediately following evaluation ]Time spent at scene (difference between Paramedic scene departure and arrival at patient side)
- Average Contact Time [ Time Frame: immediately following evaluation ]Total time spent with patient (Defined as difference between Transfer of Care and Arrival at Patient Side)

- consecutive alert, stable adults evaluated by the paramedics with potential c-spine injury after sustaining acute blunt trauma. Patient eligibility will be determined at the time of paramedic arrival at the scene based on the following criteria:
"Potential c-spine injury after sustaining acute blunt trauma" will include patients with either:
- neck pain with any mechanism of injury (subjective complaint by the patient of any pain in the posterior aspect of the neck),
- no neck pain but some visible injury above the clavicles, and/or
- neither neck pain nor visible injury, but significant mechanism of injury as determined by the paramedic at the scene.
- "Alert" is defined as a Glasgow Coma Scale score of 15 (converses, fully oriented, and follows commands).
- "Stable" refers to normal vital signs(systolic blood pressure 90 mm Hg or greater and respiratory rate between 10 and 24 breaths per minute).
- "Acute" refers to injury within the past 4 hours.
- Patients under the age of 16 years,
- Patients with penetrating trauma from stabbing or gunshot wound,
- Patients with acute paralysis (paraplegia, quadriplegia),
- Patients with known vertebral disease (ankylosing spondylitis, rheumatoid arthritis, spinal stenosis, or previous cervical spine surgery), or
- Patients referred from another hospital and transported between facilities.
