2015 ANNUAL REPORT
National Neurosurgery Quality and
With more than 20,000 patients in its database at the
end of FY15, N
QOD is the largest spine registry in
North America. As a prospective registry designed by
neurosurgeons and committed to long-term patient follow-
up with patient-reported outcomes, N
detailed, longitudinal data that is not possible for other
registries. NPA works with the Vanderbilt Institute for
Medicine and Public Health (VIMPH) to manage the
collection and analysis of N
VIMPH has provided descriptive benchmarks and risk-
adjusted variables in N
QOD reports to participating
centers since 2013. In early 2015, VIMPH began providing
individual-level surgeon reporting to participating centers
that met patient enrollment requirements.
Working in collaboration, NPA and VIMPH finished
phase one development of the N
QOD Online Spine
Predictive Calculator. The calculator will be further refined
and offered to participating centers by the end of 2015.
Based on the predictive model for outcomes after lumbar
surgery for degenerative disease, the calculator will take
input of patient details, such as age, gender, employment,
comorbidities, baseline pain, etc., and return histogram
curves demonstrating and predicting the disability, pain and
quality of life outcomes for the patient. The tool will be used
in clinic by participating registry surgeons.
QOD Lumbar Spine Registry is now in its fourth
year. The Lumbar Spine Module was launched on Feb. 22,
2012, in three academic sites. By fiscal-year end, N
had more than 21,000 patients enrolled in the Spine registry,
across 50 participating sites.
In September 2014, after an 18-month maturation
process, the N
QOD aggregate data was made available
to participating centers. Data proposals are reviewed and
evaluated by the N
QOD Data Use and Access Committee
(DUAC) for scientific merit, analytic rigor, feasibility,
clinical relevance and potential conflicts of interest.
Manuscript development and scientific analyses of the
QOD data has been a primary focus of the N
Scientific Priorities Group who have several manuscripts
in progress for publishing in late 2015. NPA expresses
appreciation to the NREF for grant funds supporting the
analytics of this work.
