2015 ANNUAL REPORT

41

National Neurosurgery Quality and

Outcomes Database

With more than 20,000 patients in its database at the

end of FY15, N

2

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

2

QOD produces

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

2

QOD data.

VIMPH has provided descriptive benchmarks and risk-

adjusted variables in N

2

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

2

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.

The N

2

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

2

QOD

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

2

QOD aggregate data was made available

to participating centers. Data proposals are reviewed and

evaluated by the N

2

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

N

2

QOD data has been a primary focus of the N

2

QOD

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.
