About this study

Official title: Strategic Use of Big Data in Spine Surgery - Testing a Digital Prediction of Outcome Tool in Clinical Praxis

The goal of this prospective, multicenter clinical trial is to determine if the use of the postoperative outcome prediction model the Dialogue Support tool can alter postoperative patient-reported outcome and satisfaction compared to current practice.

The main questions it aims to answer are:

Read more
  • Does its use alter patient-reported outcome measured by general assessment regarding leg pain and Satisfaction in lumbar spinal stenosis?
  • Does its use alter patient-reported outcome as measured by general assessment regarding arm pain and Satisfaction in cervical rhizopathy?
  • How does the Quality of Life in patients - who after assessment by spinal surgeon do not proceed to surgery - compare with patients with the same baseline profile who did undergo surgery?

Eligible participants will be presented with their predicted postoperative outcome generated by the Dialogue Support tool, as an adjunct to the ordinary assessment by a spine surgeon.

Researchers will compare participants with a matched control group from the Swedish Spine Register ("Swespine") to see if the Dialogue Support tool can alter postoperative patient-reported outcome and satisfaction.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Dialogue support toolOther

    The dialogue support tool will be used as a support for the participant and surgeon to decide on which treatment arm is optimal for the participant.

What is being measured

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

  1. Global Assessment (GA)

    A retrospective single-item question ("How is your back/leg or neck/arm pain today as compared to before the surgery?"), with six response options (not back/leg pain before surgery/completely gone/much improved/slightly improved/unchanged/worse).

    Measured: One year post surgery

Secondary outcomes (5)
  1. Oswestry Disability Index (ODI)

    assesses the impact of lumbar pain on a patient´ physical function. It consists of ten questions concerning intensity of pain, ability to care for oneself, lifting, ability to walk, ability to sit, ability to walk, sexual function, social life, sleep quality and ability to travel. Min. value 0 points (no disability) and max. value 50 points (completely disabled).

    Measured: One year post surgery

  2. Neck Disability index (NDI)

    Used to assess the self-rated disability in patients with neck pain and consisting of ten questions scaled from 0-5 concerning pain-intensity, ability to care for oneself, lifting, reading, headache, concentration, working, driving, sleep and recreational activity

    Measured: One year post surgery

  3. Euroqol-5-Dimensions quality of life questionnaire (EQ-5D)

    Assess quality of life. It describes health in 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The five levels in each dimension are worded as (1) 'not /no problems', (2) 'slight problems', (3) 'moderate problems', (4) 'severe problems', and (5) 'unable to' (mobility, self-care, usual activities), 'extreme' (pain/depression), or 'extremely' (anxiety/depression).

    Measured: One year post surgery

  4. Numeric Rating Scales for back/neck and leg/arm pain respectively (NRS)

    The NRS is a common way of grading pain experience and is presented to the patient as a line with numbers from 0-10 and the patient is asked to grade their pain experience where zero is no pain and ten is maximal pain

    Measured: One year post surgery

  5. Mortality

    The number of participants that have died within one year of surgery

    Measured: One year post surgery

Questions about this trial

What is this clinical trial studying?

A study testing Dialogue support tool in people with Constriction, Pathologic and Spine Degeneration, run by Sahlgrenska University Hospital at 10 sites in Sweden.

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 4 inclusion and 3 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 13 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in Sweden. 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. Some participants in this study may receive a placebo. 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 Catharina Parai, MD, PhD (0046313421000, catharina.parai@vgregion.se), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Global Assessment (GA) (time frame: One year post 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 NCT05817747, which also lists 1 linked publication.

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 13 May 2025.
