Large patient data registries may facilitate insights regarding real world, clinical use of DBS. Furthermore, no registry database currently exists for a multiple-source, constant-current DBS system.
We report the collected outcomes from a large-scale registry of a Deep Brain Stimulation (DBS) system capable of Multiple Independent Current Source Control (MICC) in the management of symptoms of levodopa-responsive Parkinson's disease (PD).
The Vercise DBS Registry is a prospective, on-label, multi-center, international registry sponsored by Boston Scientific. The Vercise DBS system (Boston Scientific) is a multiple-source, constant-current system. Subjects were followed up to 3-years post implantation where their overall improvement in quality of life and PD motor symptoms was evaluated. Clinical endpoints evaluated at baseline and during study follow included Unified Parkinson's disease Rating Scale (UPDRS), MDS-UPDRS, Parkinson's disease Questionnaire (PDQ-39), and Global Impression of Change. Subjects underwent either sleep or awake DBS implantation procedures.
To date, 822 patients have been enrolled (752 implanted). Improvement in quality-of-life (QoL), as assessed by PDQ-39, demonstrated improvement following implant at 6-months (-6.1-point change, p<0.0001) and up to 2-years (-2.4-point change) as compared with Baseline. Subjects with milder impairment (1545). This trend was also noted in subjects with worse disease state at Baseline (Hoehn & Yahr ≥3) who reported a greater improvement in PDQ-39 summary index. At 1-year post-implant (n=272), a 32% improvement in MDS-UPDRS III scores (stim on/meds off) compared with baseline was reported and sustained up to 2-years (n=51). Stable neuro-psychometric status (BDI-II, MoCA) was also reported. The safety profile was comparable to other published reports.   
This DBS registry represents the first comprehensive, large scale collection of real-world outcomes and evaluation of safety and effectiveness of a multiple-source, constant-current DBS system.
