CT C-spine Audit and Feedback

An interventional study of Audit and Feedback on Individual Practice Patterns in Cervical Spine Injury, Emergencies and Trauma, sponsored by University of Massachusetts, Worcester. Completed at 1 site in United States. Per ClinicalTrials.gov, last updated 2023-11-09.

Registry
Emergencies — the first condition term the registry derived for this study.

Wounds and Injuries
Why
  1. Emergencies describes something many studies share rather than a condition a study is about.
  2. The study's listed conditions name Wounds and Injuries.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

This is a prospective quality improvement study to assess the effect of using an audit-and-feedback process for emergency providers on utilization of computed tomography of the cervical spine. The objective of this study is to determine whether providing repeated individualized feedback on CT C-spine utilization to emergency providers alters their practice pattern and reduces overutilization. The investigators hypothesize that emergency providers who receive individualized feedback regarding their CT C-spine utilization on a regular basis will alter their practice pattern to reduce overutilization of this imaging study.

What researchers measure

Primary outcomes

  1. Percent NEXUS-Negative

    Percentage of CT C-spine studies that an individual provider ordered on NEXUS-negative patients

    Time frame: 6 months

Secondary outcomes

  1. Number of Fractures

    Number of cervical spine fractures identified on CT for patients who are NEXUS-negative

    Time frame: 6 months

  2. Clinically Significant Fractures

    Number of cervical spine fractures identified on CT for patients who are NEXUS-negative that required procedural intervention, hospitalization, or prolonged immobilization

    Time frame: 6 months

  3. Number of CTs

    Number of CT scans of the cervical spine ordered by each provider

    Time frame: 6 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from May 2023 to primary completion in Oct 2023, 5 months.

Of 546 non-industry interventional studies with no phase under Wounds and Injuries, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 49. This study's 5 months is below that.

Counting every sponsor, half of 599 studies reached it within 24 months; a quarter within 9 and three quarters within 48.

Wounds and Injuries covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 9, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
