Newswise — Charlottesville, VA (May 1, 2020). The May issue of Neurosurgical Focus (Vol. 48, No. 5 []) includes articles on the science of neurosurgical practice and how it has developed within the last decade.

In their introduction to the May issue, topic editors Drs. Robert E. Harbaugh, Anthony L. Asher, Kevin M. Cockroft, John Knightly, and Ganesalingam Narenthiran state,

  • To improve the quality of neurosurgical care and produce reliable clinical research, it is necessary for neurosurgeons to collect data on patient characteristics, processes of care, and clinically meaningful outcomes, to analyze these data, and to make the analysis available to individual neurosurgeons and the neurosurgical community. This is the Science of Practice algorithm.

In January 2013, when Neurosurgical Focus first examined the science of neurosurgical practice, the National Neurosurgery Quality and Outcomes Database (N2QOD) was in its infancy and limited to a database of cases of lumbar spine disorders. The N2QOD was designed to allow any US neurosurgeon, practice group, or hospital system to contribute to and access aggregate quality and outcomes data through a centralized, nationally coordinated clinical registry. Today known as the Quality Outcomes Database (QOD), it serves as a group of registries for common neurosurgical, neurovascular, and spine procedures. Other neurosurgery-related prospective clinical quality and outcomes databases have been created and are growing as well.

This issue contains reviews of the setup and expansion of these databases, and also features research obtained using data collected and maintained by them. The following is a list of articles in the May issue of Neurosurgical Focus

“Introduction. Evolution of the science of practice” by Robert E. Harbaugh et al.

“Quality Outcomes Database Spine Care Project 2012–2020: milestones achieved in a collaborative North American outcomes registry to advance value-based spine care and evolution to the American Spine Registry” by Anthony L. Asher et al.

“Editorial. Reflections on the first decade of neurosurgical science of practice: what has been accomplished; what ambitions remain to be fulfilled?” by Anthony L. Asher et al.

“Vasopressor treatment and mortality following nontraumatic subarachnoid hemorrhage: a nationwide electronic health record analysis” by George Williams, Vahed Maroufy, Laila Rasmy, et al. 

“Correlation of return to work with patient satisfaction after surgery for lumbar spondylolisthesis: an analysis of the Quality Outcomes Database” by Anthony M. DiGiorgio et al. 

“Transforming Research and Clinical Knowledge in Spinal Cord Injury (TRACK-SCI): an overview of initial enrollment and demographics” by Rachel E. Tsolinas, John F. Burke, et al.

“How the science of practice will improve evidence-based care” by Robert E. Harbaugh

“The embedded biases in hypothesis testing and machine learning” by Ghaith Habboub et al.

Founded in 1931 as the Harvey Cushing Society, the American Association of Neurological Surgeons (AANS) is a scientific and educational association with more than 10,000 members worldwide. The AANS is dedicated to advancing the specialty of neurological surgery in order to provide the highest quality of neurosurgical care to the public. All active members of the AANS are certified by the American Board of Neurological Surgery, the Royal College of Physicians and Surgeons (Neurosurgery) of Canada or the Mexican Council of Neurological Surgery, AC. Neurological surgery is the medical specialty concerned with the prevention, diagnosis, treatment and rehabilitation of disorders that affect the entire nervous system including the brain, spinal column, spinal cord, and peripheral nerves.
