OBJECTIVE: To obtain data on patient demographics, clinical practices, and long-term outcomes for patients with chronic low back pain treated with implantable drug-delivery systems. DESIGN: The National Outcomes Registry for Low Back Pain collected data at baseline, trialing, implant (or decision not to implant), and at 6- and 12-month follow-ups. Data were collected at all time points, regardless of implant status. OUTCOME MEASURES: Numeric pain ratings and Oswestry Low Back Pain Disability scores from implanted patients were compared among baseline and 6- and 12-month follow-ups. Patients were also asked to rate their quality of life and satisfaction with the therapy. RESULTS: Thirty-six physicians enrolled 166 patients to be trialed for drug-delivery systems. The trialing success rate was 93% (154 patients). In all, 136 patients (82%) were implanted. In the implant group, numeric pain ratings dropped by more than 47% for back pain and more than 31% for leg pain at the 12-month follow-up. More than 65% of implanted patients reduced their Oswestry scores by at least one level at their 12-month follow-ups compared with baseline. At 12-month follow-ups, 80% of implanted patients were satisfied with their therapy and 87% said they would undergo the procedure again. CONCLUSIONS: Current clinical practices related to trialing of drug-delivery systems resulted in the majority of patients successfully trialed. At 12-month follow-ups, implanted patients experienced reductions in numeric back and leg pain ratings, improved Oswestry scores, and high satisfaction with the therapy.
