About this study

Official title: Early Ultrasound Screening of Heterotopic Ossification After Severe Neurological Trauma in a Post-intensive Care Rehabilitation Unit

Prospective, bi-centric diagnostic, performance study on a new diagnostic procedure with ultrasounds against a reference diagnostic procedure.

The primary objective is to study the performance of ultrasound coupled with clinical examination at 1 week of admission for early screening of heterotopic ossification (HO) in patients admitted to a post intensive care rehabilitation unit (PICRU) after a severe neurologic trauma.

The CT scan at 5 weeks of admission is considered as the gold standard. CT scan reader will be blinded to clinical data.

Read the detailed description

Heterotopic ossification still pose the problem of diagnosis and clinical management that is too late and invasive when complications arise. The challenge would be to identify patients at earlier stage of HO development in order to start an early treatment. This study will focus on the performance of ultrasound in the early screening of HO for patients admitted to a post intensive care rehabilitation unit after severe neurological trauma, this population being at high risk of HO.

Patient enrollment will be performed only at the PICRU of the Raymond Poincaré Hospital (AP-HP). Another center (the imaging department of the same hospital) will participate in this research for ultrasounds and CT scans, but will not perform any recruitment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Area under the ROC (receiver operating characteristic) curve at 1 week

    Area under the ROC curve of ultrasound examination at 1 week compared CT scan at 5 weeks for making the diagnosis of HO.

    Measured: at 1 week

Secondary outcomes (6)
  1. Sensitivity

    Sensitivity of ultrasound examination at 1 week for making the diagnosis of HO, the CT scan at 5 weeks of admission being considered as the gold standard.

    Measured: at 1 week

  2. Specificity

    Specificity of ultrasound examination at 1 week for making the diagnosis of HO, the CT scan at 5 weeks of admission being considered as the gold standard.

    Measured: at 1 week

  3. Positive predictive value and negative predictive value

    Positive predictive value and negative predictive value of ultrasound examination at 1 week for making the diagnosis of HO, the CT scan at 5 weeks of admission being considered as the gold standard.

    Measured: at 1 week

  4. Likelihood-ratio of ultrasound

    Likelihood-ratio of ultrasound examination at 1 week for making the diagnosis of HO, the CT scan at 5 weeks of admission being considered as the gold standard.

    Measured: at 1 week

  5. Area under the ROC curve at 5 weeks

    Area under the ROC curve of ultrasound examination at 5 weeks compared with CT scan at 5 weeks for making the diagnosis of HO.

    Measured: at 5 weeks

  6. Clinical examination

    Area under the ROC curve of clinical examination at 1, 2, 3, 4, 5 weeks of admission compared with CT scan at 5 weeks to screen HO.

    Measured: weekly from week-1 to week-5

Questions about this trial

What is this clinical trial studying?

A study testing Ultrasound, CT scan and Clinical examination in people with Heterotopic Ossification, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 17 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Julie PAQUEREAU, MD (+33 1 47 10 70 82, julie.paquereau@aphp.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Area under the ROC (receiver operating characteristic) curve at 1 week (time frame: at 1 week). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Mar 2023.
