Research using the Quality Outcomes Database: accomplishments and future steps toward higher-quality real-world evidence.

OBJECTIVE: The Quality Outcomes Database (QOD) was established in 2012 by the NeuroPoint Alliance, a nonprofit organization supported by the American Association of Neurological Surgeons. Currently, the QOD has launched six different modules to cover a broad spectrum of neurosurgical practice-namely lumbar spine surgery, cervical spine surgery, brain tumor, stereotactic radiosurgery (SRS), functional neurosurgery for Parkinson's disease, and cerebrovascular surgery. This investigation aims to summarize research efforts and evidence yielded through QOD research endeavors. METHODS: The authors identified all publications from January 1, 2012, to February 18, 2023, that were produced by using data collected prospectively in a QOD module without a prespecified research purpose in the context of quality surveillance and improvement. Citations were compiled and presented along with comprehensive documentation of the main study objective and take-home message. RESULTS: A total of 94 studies have been produced through QOD efforts during the past decade. QOD-derived literature has been predominantly dedicated to spinal surgical outcomes, with 59 and 22 studies focusing on lumbar and cervical spine surgery, respectively, and 6 studies focusing on both. More specifically, the QOD Study Group-a research collaborative between 16 high-enrolling sites-has yielded 24 studies on lumbar grade 1 spondylolisthesis and 13 studies on cervical spondylotic myelopathy, using two focused data sets with high data accuracy and long-term follow-up. The more recent neuro-oncological QOD efforts, i.e., the Tumor QOD and the SRS Quality Registry, have contributed 5 studies, providing insights into the real-world neuro-oncological practice and the role of patient-reported outcomes. CONCLUSIONS: Prospective quality registries are an important resource for observational research, yielding clinical evidence to guide decision-making across neurosurgical subspecialties. Future directions of the QOD efforts include the development of research efforts within the neuro-oncological registries and the American Spine Registry-which has now replaced the inactive spinal modules of the QOD-and the focused research on high-grade lumbar spondylolisthesis and cervical radiculopathy.

Sleep Disturbances in Cervical Spondylotic Myelopathy: Prevalence and Postoperative Outcomes-an Analysis From the Quality Outcomes Database.

STUDY DESIGN: Prospective observational study, level of evidence 1 for prognostic investigations. OBJECTIVES: To evaluate the prevalence of sleep impairment and predictors of improved sleep quality 24 months postoperatively in cervical spondylotic myelopathy (CSM) using the quality outcomes database. SUMMARY OF BACKGROUND DATA: Sleep disturbances are a common yet understudied symptom in CSM. MATERIALS AND METHODS: The quality outcomes database was queried for patients with CSM, and sleep quality was assessed through the neck disability index sleep component at baseline and 24 months postoperatively. Multivariable logistic regressions were performed to identify risk factors of failure to improve sleep impairment and symptoms causing lingering sleep dysfunction 24 months after surgery. RESULTS: Among 1135 patients with CSM, 904 (79.5%) had some degree of sleep dysfunction at baseline. At 24 months postoperatively, 72.8% of the patients with baseline sleep symptoms experienced improvement, with 42.5% reporting complete resolution. Patients who did not improve were more like to be smokers [adjusted odds ratio (aOR): 1.85], have osteoarthritis (aOR: 1.72), report baseline radicular paresthesia (aOR: 1.51), and have neck pain of ≥4/10 on a numeric rating scale. Patients with improved sleep noted higher satisfaction with surgery (88.8% vs 72.9%, aOR: 1.66) independent of improvement in other functional areas. In a multivariable analysis including pain scores and several myelopathy-related symptoms, lingering sleep dysfunction at 24 months was associated with neck pain (aOR: 1.47) and upper (aOR: 1.45) and lower (aOR: 1.52) extremity paresthesias. CONCLUSION: The majority of patients presenting with CSM have associated sleep disturbances. Most patients experience sustained improvement after surgery, with almost half reporting complete resolution. Smoking, osteoarthritis, radicular paresthesia, and neck pain ≥4/10 numeric rating scale score are baseline risk factors of failure to improve sleep dysfunction. Improvement in sleep symptoms is a major driver of patient-reported satisfaction. Incomplete resolution of sleep impairment is likely due to neck pain and extremity paresthesia.

Washington Committee for Neurological Surgery: The Evolution of Neurosurgery's Involvement in Public Policy.

The American Association of Neurological Surgeons/Congress of Neurological Surgeons Washington Committee was formed in 1975 to establish a means for neurosurgery to influence federal health care policy. In response to growing federal health care legislation and regulation, the Washington Committee expanded from its original six members in 1975 to 35 invited liaisons and members by 2020. The Washington Committee, through the Washington Office, expanded political lobbying capacity into numerous important areas of health care policy, including Current Procedural Terminology coding and Medicare reimbursement, Federal Drug Administration (FDA) regulation, healthcare quality oversight, emergenc medical services, treatment guidelines, treatment outcome registries, medical liability reform, research funding, and information dissemination. Over 45 yr, the Washington Committee has become an indispensable resource for shaping public policy affecting neurosurgery training, research, and practice.

Quality Reporting in Neurological Surgery: Practice Adherence to Quality Payment Program Guidelines.

Recent legislation has changed quality reporting in neurological surgery. The present study summarizes the reporting of objectives and measures outlined by the Quality Payment Program (QPP) and assesses how practices are preparing to comply. In February 2017, 220 neurosurgical practices were surveyed regarding their adherence to quality reporting objectives and measures. Survey responders were asked to report infrastructure-level data including practice type and number of providers. Furthermore, we evaluated the reporting of quality and advancing care measures outlined by the QPP. Assessment of quality measures was focused on those related to neurosurgical patient management. A total of 27 responses were obtained. Practices consisted of 8 academic (30%), 16 physician-owned (59%), and 3 hospital-owned (11%) neurosurgical practices. Of the 27 total responders, 18 indicated their adherence to a host of quality and advancing care measures. Practice type was strongly associated with the number of quality measures performed (P = .020, Wilcoxon rank-sum test). Physician-owned practices reported performing a median of 5 quality measures (interquartile range, 4.5-9.5), while practices in academic and hospital-owned groups reported performing 12 quality measures (interquartile range, 9.5-13.5). Forty-five percent of physician-owned practices reported performing at least 6 quality measures, whereas 100% of academic and hospital-owned practices reported the same benchmark (P = .038, Fisher's exact test). Performance of advancing care measures was not associated with practice type. Compared to other practice types, the rate of quality reporting among physician-owned neurosurgical practices appears to be modest thus far, which may influence future reimbursement adjustments.

A History of the Council of State Neurosurgical Societies.

As neurological surgery evolved into its own subspecialty early in the 20th century, a need arose to create an environment for communication and education among those surgeons working in this burgeoning surgical discipline. As the socioeconomic climate in health care began to change in the United States, an unforeseen need arose that was outside the scope of the American Association of Neurological Surgeons, Congress of Neurological Surgeons, and Society of Neurological Surgeons. The capacity to understand and address the evolving socioeconomic landscape and to offer a platform for advocacy required a new entity. Grassroots efforts of neurosurgeons at the state level ultimately yielded a formal organization of state neurosurgical societies to fill this void by recognizing, understanding, and addressing socioeconomic factors affecting the practice of neurological surgery. This formal organization became the Council of State Neurosurgical Societies (CSNS). The CSNS provides a forum in which state societies can meet to identify, understand, and advocate for policies on behalf of organized neurosurgery. The purpose of this paper is to detail the history of the formation of the CSNS. By understanding this history and the need for the development of the CSNS, it is hoped that its evolving role as a voice for neurological surgeons in the modern era of health care will be made clear.

Technique for collection of cerebrospinal fluid from the cisterna magna in rat.

Cerebrospinal fluid (CSF) is in direct contact with the extracellular space in the central nervous system (CNS), and biological changes in the brain can be reflected in CSF. In the present article, a procedure for collection of CSF in rats is described. The technique quickly and reliably yields large quantities of CSF (50-150 microl) in rats. More importantly, blood contamination of the CSF is avoided. Furthermore, detections of ATP and interleukin (IL)-1 beta in the CSF have been carried out. ATP concentration in the CSF samples was between 8.3 and 15.8 nM, with an average of 10.5+/-0.83 nM (mean+/-SEM). The concentrations of IL-1beta were below the detection limit in the CSF in the laminectomy control rats, but it increased to 0.26+/-0.07 ng/ml at 1h after spinal cord injury. This technique offers an alternative method to surgical cannulation for the collection of CSF in rats.

Nonhemorrhagic cord contusion after percutaneous fiducial placement: case report and surgical recommendations.

STUDY DESIGN: Single case report and extensive literature review. OBJECTIVES: To present the first such report of cervical cord contusion after the percutaneous placement of gold-seed fiducials. The pathomechanics and surgical recommendations are reviewed. BACKGROUND: Spinal cord injuries are well documented in the medical literature. These injuries range from cord contusion to transection and result primarily from trauma. A single case report of a patient who was found to have a nonhemorrhagic cervical spinal cord contusion after percutaneous fiducial implantation is presented. METHODS: Single case report. RESULTS: The patient underwent percutaneous placement of fiducials for stereotactic radiosurgery for a nerve sheath tumor. Postoperatively she had primarily sensory complaints; no motor deficits were detected on neurological examination. Neuroimaging studies demonstrated nonhemorrhagic cervical cord contusion. She was treated conservatively and had complete resolution of her symptoms. CONCLUSIONS: The likely mechanism for the contusion was neck hyperextension during thrusting maneuvers during fiducial implantation. This is yet another report of normal intraoperative-evoked potentials with postoperative neurological sequelae. A dedicated team approach involving ancillary staff, anesthesiologists, and surgeons should be utilized to avert this potentially devastating complication.

Does anterior plating maintain cervical lordosis versus conventional fusion techniques? A retrospective analysis of patients receiving single-level fusions.

A retrospective review of medical records and radiographs of patients receiving anterior cervical discectomy and fusion (ACDF) without anterior plating and with anterior plating was performed. The objective of the study was to determine whether a difference exists in cervical lordotic alignment between subjects undergoing single-level ACDF with and without anterior cervical plating instrumentation for symptomatic cervical disc disease. Collapse or settling of grafted bone into the vertebral endplates with resulting kyphotic deformity of the cervical spine is a commonly described complication of anterior discectomy and fusion. Despite the increasing use of instrumentation for the treatment of cervical spine injuries and degenerative conditions, little is known regarding lordotic alignment of the cervical spine in patients who receive plating instrumentation compared with conventional fusion without plating. Accumulating evidence suggests that plating is superior to non-plating techniques in patients with multiple level cervical disc lesions in regard to fusion, return to work rates, and complication rates; however, little is known about maintenance of lordotic curve alignment in single- and multiple-level procedures. Neutral lateral cervical radiographs of 57 patients who underwent single-level ACDF between 1994 and 1999 with anterior screw plates (n = 26), and conventional single-level fusion without anterior screw plates (n = 21) were retrospectively assessed. Measurements were made on weight-bearing lateral cervical radiographs to assess overall sagittal spinal alignment and intersegmental sagittal alignment at the surgical site before surgery, immediately after surgery, 4 to 12 weeks after surgery, and 12+ months after surgery. The average magnitude of overall lordosis measured between C2 and C7 decreased 4.2 degrees in the non-plated group, while being preserved in the plated group. This finding did not reach statistical significance in the long-term follow-up. At the surgical site, the segmental contribution to lordosis decreased an average 2.5 degrees in the non-plated group versus an increase of 5.67 degrees in the plated group, and this finding was statistically significant between groups measured at all pre- and postoperative visits (p < 0.01). On average, the plating procedure resulted in preserving overall lordosis while increasing the magnitude of segmental lordosis at the surgical site. In comparison, the conventional method resulted in a net loss of overall lordosis and segmental lordosis at the surgical site.
