About this study

Official title: Establishment of Artificial Intelligence Algorithms Based Clinical Prediction Model for Patients With Postoperative Symptomatic Spinal Epidural Hematoma After Spinal Surgery

The goal of this observational study is to establish a clinical prediction model based on artificial intelligence algorithms for patients with postoperative symptomatic spinal epidural hematoma(PSSEH) after spinal surgery. The investigators will collect the features of 2000 patients as the training set to train the models using AI algorithms, then recruit a prospective cohort of 2000 patients to test if the trained model is precise and consistent to predict the occurrence of PSSEH as well as to find out whether there is any new risk factor of PSSEH.

Read the detailed description

Firstly, the investigators plan to collect the features of 2000 patients who received spinal surgery at Peking University Third Hospital from January 2014 to December 2024, including those with PSSEH and the controls, as the training set to build up a prediction model based on multiple AI algorithms. Then, the investigators will choose the optimal model through comparing various features, assessing the robustness of the model quantitatively using k-fold cross validation and exploring the influence of all features on the output of the final model by means such as SHAP. Lastly, the investigators will recruit a prospective cohort of approximately 2000 patients who receive spinal surgery from January 2025 to December 2026 at Peking University Third Hospital and collect the same features as the training set to test if the trained prediction model is precise and consistent to predict the occurrence of PSSEH and whether there is any feature , undiscovered before, that is strongly related to PSSEH.

What is being measured

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

  1. if the patients have postoperative symptomatic spinal epidural hematoma

    patients with symptoms as below：

    1. Persistent wound bleeding;
    2. Exacerbation of wound pain;
    3. Radicular symptoms-severe low back pain, shoulder and neck pain;
    4. Motor dysfunction-limb muscle weakness, muscle atrophy;
    5. Sensory abnormalities-reduced or lost tactile sensation, pain, and temperature perception;
    6. pharyngeal discomfort, shortness of breath, and difficulty breathing;
    7. Urinary and bowel dysfunction-urinary retention, urinary incontinence, dysporia;
    8. Hematoma compressing the dura mater discovered during hematoma evacuation surgery;
    9. Suspected PSSEH based on the surgeon's assessment；
    10. Definitive diagnosis by MRI imaging;

    Measured: within 2 weeks after spinal surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Spinal Epidural Hematoma, run by Peking University Third Hospital at 1 site in China.

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 1 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 22 Oct 2026. 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 China. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Orthopedics Department of Peking University Third Hospital (008618811597977, 2411210441@pku.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

if the patients have postoperative symptomatic spinal epidural hematoma (time frame: within 2 weeks after spinal surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06633848, which also lists 4 linked publications.

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 22 Oct 2026; AzTrials last refreshed its copy on 7 Nov 2026.
