Is computed tomography of nonvisualized C7-T1 cost-effective?

Area of Science:

• Radiology
• Orthopaedic Surgery
• Health Economics

Background:

• Inadequate visualization of the C7-T1 junction on conventional radiography is common in trauma patients.
• Early and accurate diagnosis of C7-T1 fractures is crucial to prevent neurological sequelae and long-term instability.

Purpose of the Study:

• To determine the cost-effectiveness of computed tomography (CT) for evaluating the C7-T1 level when conventional radiography is insufficient.
• To assess the economic value of CT in identifying C7-T1 fractures and guiding treatment decisions.

Main Methods:

• Retrospective cohort study of 360 trauma patients with inadequately visualized C7-T1 levels on radiography.
• Review of CT scans for C7-T1 fractures, classification of fracture severity (unstable, potentially unstable), and consultation with an orthopaedic surgeon.
• Cost-effectiveness analysis based on Medicare reimbursement data for identified fractures and required interventions.

Main Results:

• Eleven C7-T1 fractures were identified among 360 patients.
• The cost-effectiveness of CT per identified fracture was $9,192.
• Cost-effectiveness varied based on fracture instability: $16,852 for potentially or definitely unstable fractures and $50,557 for definitely unstable fractures.

Conclusions:

• Computed tomography (CT) of the C7-T1 level is a cost-effective diagnostic tool when conventional radiography is inadequate.
• The cost-effectiveness is particularly significant given the potential for high morbidity and long-term complications in the young trauma population.
• CT imaging aids in timely management, potentially reducing future healthcare costs associated with untreated C7-T1 injuries.
