In July 2010, the Society of Neurological Surgeons (SNS) introduced regional courses to promote patient safety and teach fundamental skills and knowledge to all postgraduate Year 1 (PGY1) trainees entering Accreditation Council for Graduate Medical Education (ACGME)–accredited US neurosurgery residency programs. Data from these courses demonstrated significant didactic learning and high faculty and resident satisfaction with hands-on training. Here, the authors evaluated the durability of learning from and the relevance of participation in SNS PGY1 courses as measured midway through PGY1 training.

Methods

Resident participants were resurveyed 6 months after boot camp course attendance to assess knowledge retention and course effectiveness. Exposure to relevant hands-on experiences during PGY1 training and the subjective value of pre-residency simulated training in the courses were assessed.

Results

Ninety-four percent of all residents entering US PGY1 neurosurgical training participated in the 2010 SNS boot camp courses. One hundred sixty-four (88%) of these resident participants responded to the survey. Six months after course completion, 99% of respondents believed the boot camp courses benefited beginning neurosurgery residents and imparted skills and knowledge that would improve patient care. The PGY1 residents' knowledge of information taught in the courses was retained 6 months after initial testing (p < 0.0001).

Conclusions

The learning and other benefits of participation in a national curriculum for residents entering PGY1 neurosurgical training were maintained 6 months after the courses, halfway through the initial training year.

OBJECTIVE

Despite rapid development and expansion of neuromodulation technologies, knowledge about device and/or therapy durability remains limited. The aim of this study was to evaluate the long-term rate of hardware and therapeutic failure of implanted devices for several neuromodulation therapies.

METHODS

The authors performed a retrospective analysis of patients’ device and therapy survival data (Kaplan-Meier survival analysis) for deep brain stimulation (DBS), vagus nerve stimulation (VNS), and spinal cord stimulation (SCS) at a single institution (years 1994–2015).

RESULTS

During the study period, 450 patients underwent DBS, 383 VNS, and 128 SCS. For DBS, the 5- and 10-year initial device survival was 87% and 73%, respectively, and therapy survival was 96% and 91%, respectively. For VNS, the 5- and 10-year initial device survival was 90% and 70%, respectively, and therapy survival was 99% and 97%, respectively. For SCS, the 5- and 10-year initial device survival was 50% and 34%, respectively, and therapy survival was 74% and 56%, respectively. The average initial device survival for DBS, VNS, and SCS was 14 years, 14 years, and 8 years while mean therapy survival was 18 years, 18 years, and 12.5 years, respectively.

CONCLUSIONS

The authors report, for the first time, comparative device and therapy survival rates out to 15 years for large cohorts of DBS, VNS, and SCS patients. Their results demonstrate higher device and therapy survival rates for DBS and VNS than for SCS. Hardware failures were more common among SCS patients, which may have played a role in the discontinuation of therapy. Higher therapy survival than device survival across all modalities indicates continued therapeutic benefit beyond initial device failures, which is important to emphasize when counseling patients.
