About this study

Official title: Prospective, Observational Study Evaluating the Ability of Clinical Factors to Predict Interventional Treatment Outcomes for Low Back Pain (LBP)

In this study, we are attempting to determine which factors are associated with interventional treatment outcome for LBP (and to what extent). Up to 346 patients with LBP who are considered to be good candidates for therapeutic interventional procedures will be given a complete history and physical exam, which includes the assessment of Waddell signs, and querying them regarding factors shown in non-interventional studies or retrospective studies evaluating interventional treatments to be associated with negative treatment outcomes. These factors include the presence of Waddell and other physical exam signs, opioid use, allergies, psychopathology, concomitant pain conditions, a 6-point Likert scale on expectations, sleep abnormalities, secondary gain (e.g. medical board or litigation), procedure-related pain including from a 1 ml standardized injection, obesity, and smoking history. They will then proceed to undergo their scheduled intervention, which will be limited to epidural steroid injections (ESI), facet blocks and if positive, radiofrequency denervation, and sacroiliac (SI) joint injections. A positive outcome will be defined as 2-point or greater decrease in average pain score at 1-month and a score of > 3 on a 1-5 Likert satisfaction scale. Those with a positive outcome at 1-month will remain in the study and be followed again at 3-months.

Read the detailed description

This will be an observational study with a 3-month follow-up. The course of clinical treatment will be decided by a physician independent of the research. Besides filling out questionnaires and standardized follow-up visits, all subjects will receive the same care they would if they did not participate in the study. The study will be discussed with the subjects and they will be enrolled in the study after it is determined that they meet selection criteria and are scheduled for one of the above injections. They will then fill out 3 questionnaires (Oswestery disability index, Athens insomnia scale, QIDS SR-16. All procedures will be performed with fluoroscopy. Following each procedure, the procedure-related pain will be reported on a 0-10 scale (all patients will receive as much 1% lidocaine local anesthetic as is necessary), including the reported pain to the standardized skin wheal at the start of the procedure.

Patients will then receive standardized epidural steroid injections (transforaminal or interlaminar), sacroiliac joint injections, or facet blocks and radiofrequency denervation if they experience a positive block. Details about these procedures are available upon request.

No patients will be permitted additional interventions between the time of their procedure and follow-up visits. Rescue medications will be in the form of either tramadol, NSAIDs or if the patient is on opioids, a < 20% increase in dose. The first follow-up visit will be scheduled 1 month from the start of treatment for ESI and SI joint patients, and 1 month after RF denervation in positive diagnostic facet block responders. In those facet block patients who obtain prolonged relief from the "diagnostic" medial branch block, follow-up will be 1 month after the block (these patients may proceed to have denervation if their pain recurs after 1 month but before their final 3-month follow-up, and their 3-month follow-up will be 3 months after their medial branch block). A positive outcome will be defined as a greater or equal to 2-point decrease in average LBP (or leg pain for those who underwent an ESI) coupled with a positive satisfaction rating (> 3 on a 5-point scale). Subjects who obtain a positive outcome at their initial 1-month follow-up visit will remain in the study and return for the final 3-month follow-up visit. Those with a negative outcome will exit the study "per protocol" to receive standard care, which may consist of other injections or non-rescue medications such as antidepressants and anticonvulsants. Subjects who obtain a positive outcome at 1-month but experience a recurrence before their 3-month follow-up visit will also exit the study per protocol, with their final outcome measures recorded before they receive standard care.

In those who receive ESI, a smaller parallel study will be done evaluating the association between allergies and outcome. Allergies will be categorized as immunologically based or not.

What participants receive

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

  • Facet interventionProcedure or surgery

    Also called Medial branch block and radiofrequency ablation

    Diagnostic block of the nerves innervation the lumbar facet joint. If this block is positive (greater or equal to 50% relief), the participant will proceed to radiofrequency nerve ablation when the pain returns

  • Sacroiliac joint injectionProcedure or surgery

    Injection of steroid and local anesthetic into SI joint

  • Epidural steroid injectionProcedure or surgery

    Transforaminal or interlaminar injection of steroid epidurally

Study groups in NCT02329951
Study groupRoleWhat they receive
Epidural steroid injectionsPatients will receive a single interlaminar epidural steroid injection with 60 mg depomethylprednisolone, 1.5 ml of 0.25% bupivacaine and 1.5 ml of saline or a transforaminal epidural steroid injection with 60 mg depomethylprednisolone, 1.5 ml of 0.25% bupivacaine and 0.5 ml of saline.
Receives: Procedure: Epidural steroid injection
Facet interventionsPatients will receive diagnostic medial branch (facet joint nerve) blocks with 0.5 ml of 0.5% bupivacaine. If they experience a positive block (> 50% pain relief lasting more than 3 hours), they will then receive radiofrequency denervation.

Questions about this trial

What is this clinical trial studying?

An observational study of Low Back Pain and Lumbar Radiculopathy, run by Johns Hopkins University at 1 site in United States.

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 6 inclusion and 7 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: finished, as of the sponsor's last update on 9 Dec 2021. 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 United States. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean reduction in average pain score (time frame: 1 month). 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 NCT02329951, which also lists 2 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 9 Dec 2021.
