Low Back Pain
Conditions
Brief summary
This is an independent prospective, noninterventional, observational post-market data collection of the patient-reported effectiveness, ongoing safety and satisfaction outcomes for patients treated with the Intracept Procedure at a single study site.
Detailed description
The Investigator Sponsor will initially approach patients planning to undergo the Intracept Procedure to discuss their interest in learning more about the study. With patient permission, contact information will be forwarded to a third-party research organization which will contact the patient to explain more about the study and to gather Verbal Informed Consent. Study data will be collected by the University of Utah research staff via 4 telephone study visits under the direction of the Sponsor Investigator. The study research staff will enter the study data directly into a study database and issue the subject stipend after the completion of each study visit. Data will be analyzed by a statistician under the direction of the Sponsor Investigator for this single-site study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Oswestry Disability Index (ODI) Change | 3 months | Validated questionnaire of low back pain related disability. Comprised of 10 questions evaluating the impact of low back pain on activities of daily living. The ODI is scored on a scale of 0 (no disability) to 100 (complete disability), with categories of 0-20 (minimal disability), 21-40 (moderate disability), 41-60 (severe disability), 61-80 (crippling back pain), and 81-100 (bed-bound or exaggerating). Comparison of mean ODI baseline to 3 months. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Oswestry Disability Index (ODI) Change | 12 months | Mean Improvement in ODI scores from baseline (scale 0 to 100): Validated questionnaire of low back pain related disability. Comprised of 10 questions evaluating the impact of low back pain on activities of daily living. The ODI is scored on a scale of 0 (no disability) to 100 (complete disability), with categories of 0-20 (minimal disability), 21-40 (moderate disability), 41-60 (severe disability), 61-80 (crippling back pain), and 81-100 (bed-bound or exaggerating). Comparison of mean ODI baseline to 3 months. |
| Numeric Pain Rating Scale (NPRS) | 3 months | Mean change in patient-reported low back pain from baseline. The scale is from 0 (no pain) to 10 (worst pain imaginable). |
| Combined Responder Rates (improvement thresholds of ODI ≥ 15 and NPRS ≥ 2) | 3 months | Percent of responders meeting both thresholds |
| PROMIS 29 Change | 3 months | Mean change in PROMIS-29 from baseline. (PROMIS-29 includes Numeric Rating Score (NRS) and Seven Health Domains. \[NRS 0-10 zero being none and 10 the worst. Seven health domains scaled 1-5: physical function (1 unable to do to 5 without any difficulty), fatigue (1 not at all and 5 very much), pain interference (1 not at all and 5 very much), depressive symptoms (1 never and 5 always), anxiety (1 never and 5 always), ability to participate in social roles and activities (1 never and 5 always), and sleep disturbance(1 not at all and 5 very much)\]) |
| Quadrants of % reduction in low back pain from baseline to each follow-up period. | 3 months | Review of the % of low back pain reduction in participants |
| Responder rates for Oswestry Disability Index (ODI) | 3 months | The proportion of subjects who achieve ≥ 15-point reduction in ODI from baseline to each follow-up period. This would indicate a reduction in how much lower back pain is affecting participants' daily activities following the procedure. The Oswestry Disability Index (ODI) is a validated questionnaire of low back pain related disability comprised of 10 questions evaluating the impact of low back pain on activities of daily living. The ODI is scored on a scale of 0 (no disability) to 100 (complete disability), with categories of 0-20 (minimal disability), 21-40 (moderate disability), 41-60 (severe disability), 61-80 (crippling back pain), and 81-100 (bed-bound or exaggerating). Comparison of mean ODI baseline to 3 months. |
| Responder rates for the Numeric Pain Rating Scale (NPRS) | 3 Months | The proportion of subjects who achieve a ≥ 2-point reduction in the NPRS from baseline to each follow-up period. The scale is from 0 (no pain) to 10 (worst pain imaginable). |
| Responder rates the Numeric Pain Score | 12 Months | the proportion of subjects who achieve a ≥ 2-point reduction in numeric pain score from baseline to each follow-up period. The scale is from 0 (no pain) to 10 (worst pain imaginable). |
| Responder rates for the Numeric Pain Score | 24 Months | the proportion of subjects who achieve a ≥ 2-point reduction in numeric pain score from baseline to each follow-up period. The scale is from 0 (no pain) to 10 (worst pain imaginable). |
| Narcotic use | 3 Months | The proportion of patients actively utilizing narcotics for low back pain at each follow-up period. |
| Low back pain injections | 3 Months | The proportion of patients utilizing injections for low back pain of the same treatment region at each follow-up period. |
| Low back pain interventions or surgery | 3 Months | The proportion of patients with pain interventions or surgery for low back pain of the same treatment region at each follow-up period |
| Work Impact | 12 Months | Patient work status at 12 months indicated by subject using this scale: No impact to my ability to work; Working with restrictions; Had to get a different job due to low back pain; Unable to work at all/disabled by my low back pain (e.g. retired, unemployed); Not currently working unrelated to low back pain; Other. If a subject is working with restrictions, they are asked to specify: Reduced hours; Slower pace; Less heavy work; Not regular job. Subjects are also asked the question: How many workdays have you missed due to low back pain? |
| Patient Global Impression of Change (PGIC) | 3 Months | PGIC at each follow-up period. The subject is asked to rate their low back pain progress with the scale: Very Much Improved; Much Improved; Minimally Improved; No Change; Minimally worse; Much Worse; Very Much Worse. |
| Patient-reported procedure-related adverse events | 3 Months | Patient-reported procedure-related adverse events including new LBP and/or leg pain at each follow-up period |
