Universal Screening for Blunt Cerebrovascular Injury (PRaCTUS BCVI)
Pragmatic Randomized Clinical Trial of Universal Screening for BCVI
The goal of this clinical trial is to test whether screening all major blunt trauma patients for blood vessel injuries in the neck and head using CT scans (universal screening) leads to fewer strokes and stroke-related deaths compared to screening only selected patients who meet specific risk criteria (selective screening).
This is a pilot feasibility study. The main questions this study aims to answer are:
Can trauma centers that currently use selective screening successfully switch to universal screening? Are the definitions used to identify and measure outcomes clear and applied consistent across all participating hospitals? Do stroke complications occur frequently enough to support a larger, future clinical trial? Can participating trauma centers reliably track and report the number of CT scans performed for this purpose?
Participating trauma centers in the study will: Continue using their existing selective screening approach at the start of the study Switch to universal CT screening of all major blunt trauma patients at an assigned point during the 12-month study period Submit de-identified patient data to the coordinating center using a secure electronic database Researchers will use the result of this initial feasibility study to determine whether a larger clinical trial comparing the two screening strategies is feasible.

詳細な説明
This study evaluates the feasibility of conducting a clinical trial comparing outcomes for selective screening versus universal screening in adult major blunt trauma patients at level 1 and 2 trauma centers in the United States. The primary outcome is BCVI-related ischemic stroke. The secondary outcome is a composite of BCVI-related stroke or stroke-related death.
The design of this study is a pragmatic stepped-wedge cluster-randomized trial. The choice between SS and US is an institutional policy decision rather than an individual patient decision, the unit of randomization is the Trauma Center (TC). Both strategies are widely used at TCs in the United States and considered standard of care. Genuine clinical equipoise exists. The principal risk of US is additional imaging and treatment; the principal risk of SS is a missed injury and a potentially preventable stroke. Neither strategy has been shown to be superior with respect to patient-centered outcomes.
Discussion of the trial and initial findings are expected to facilitate recruitment for the definitive trial, which is anticipated to enroll at least 20 Level 1 and 2 TCs for three or more years.

Number of Participants with BCVI-related Ischemic Stroke
時間枠:In-hospital, from admission to discharge or in-hospital death; aggregated over the 12-month data-collection period by screening condition
|
BCVI-related ischemic stroke is defined as any ischemic stroke occurring during the hospital stay in a vascular territory suggestive of cervical arterial injury, or any ischemic stroke occurring during the hospital stay in a patient with confirmed BCVI (or before discharge or patient death). Strokes present on admission imaging will be recorded but analyzed separately and not classified as BCVI-related. |

Incidence of BCVI-related stroke, measured at the population level as events per 1,000 major blunt trauma admissions and compared between screening conditions. BCVI-related stroke is any in-hospital ischemic stroke in a vascular territory suggestive of cervical arterial injury or in a patient with confirmed BCVI; hemorrhagic strokes and strokes on admission imaging are excluded. |
