RESUMEN
Background: The positive predictive value (PPV) of the International Classification of Diseases, Ninth Revision-Clinical Modification (ICD-9-CM) code for "essential and other specified forms of tremor" in identifying essential tremor (ET) cases was found to be less than 50%. The ability of the ICD-10-CM G25.0 code for "essential tremor" to identify ET has not been determined. The study objective was to determine the PPV of the G25.0 code. Methods: Patients in a tertiary health system with a primary care encounter associated with ICD-10-CM code G25.0 in 2022 underwent medical record review to determine if the consensus criteria from the International Parkinson and Movement Disorder Society for an ET diagnosis were met. Results: 442 patients were included. The PPV of G25.0 in identifying probable ET cases was 74.7% (95% confidence interval (CI) 70.4-78.5%). Among patients prescribed propranolol, the PPV improved to 87.8% (95% CI 78.0-93.6%). Discussion: Compared to the ICD-9-CM code 333.1, G25.0 is superior for identifying ET cases. A potential limitation of this study is that the consensus criteria applied relies on nonspecific physical exam findings which may lead to an overestimation of the PPV of G25.0. Highlights: The ICD-10-CM diagnosis code for essential tremor has not been previously validated. The objective of this study was to determine the PPV of the G25.0 code. The PPV in identifying essential tremor cases was 74.7%. The PPV improved among patients prescribed propranolol.

BACKGROUND: Occipital neuralgia (ON) is a debilitating headache disorder. Due to the rarity of this disorder and lack of high-level evidence, a clear framework for choosing the optimal surgical approach for medically refractory ON incorporating shared decision making with patients does not exist. METHODS: A literature review of studies reporting pain outcomes of patients who underwent surgical treatment for ON was performed, as well as a retrospective chart review of patients who underwent surgery for ON within our institution. RESULTS: Thirty-two articles met the inclusion criteria. A majority of the articles were retrospective case series (22/32). The mean number of patients across the studies was 34 (standard deviation (SD) 39). Among the 13 studies that reported change in pain score on 10-point scales, a study of 20 patients who had undergone C2 and/or C3 ganglionectomies reported the greatest reduction in pain intensity after surgery. The studies evaluating percutaneous ablative methods including radiofrequency ablation and cryoablation showed the smallest reduction in pain scores overall. At our institution from 2014 to 2023, 11 patients received surgical treatment for ON with a mean follow-up of 187 days (SD 426). CONCLUSION: Based on these results, the first decision aid for selecting a surgical approach to medically refractory ON is presented. The algorithm prioritizes nerve sparing followed by non-nerve sparing techniques with the incorporation of patient preference. Shared decision making is critical in the treatment of ON given the lack of clear scientific evidence regarding the superiority of a particular surgical method.

BACKGROUND: Despite higher rates of seizure freedom, a large proportion of patients with medically refractory seizures who could benefit from epilepsy surgery do not receive surgical treatment. This literature review describes the association of race and insurance status with epilepsy surgery access and outcomes. METHODS: Searches in Scopus and PubMed databases related to disparities in epilepsy surgery were conducted. The inclusion criteria consisted of data that could be used to compare epilepsy surgery patient access and outcomes by insurance or race in the United States. Two independent reviewers determined article eligibility. RESULTS: Of the 289 studies reviewed, 26 were included. Most of the studies were retrospective cohort studies (23 of 26) and national admissions database studies (13 of 26). Of the 17 studies that evaluated epilepsy surgery patient demographics, 11 showed that Black patients were less likely to receive surgery than were White patients or had an increased time to surgery from seizure onset. Nine studies showed that patients with private insurance were more likely to undergo epilepsy surgery and have shorter time to surgery compared with patients with public insurance. No significant association was found between the seizure recurrence rate after surgery with insurance or race. CONCLUSIONS: Black patients and patients with public insurance are receiving epilepsy surgery at lower rates after a prolonged waiting period compared with other patients with medically refractory epilepsy. These results are consistent across the current reported literature. Future efforts should focus on additional characterization and potential causes of these disparities to develop successful interventions.

RESUMEN
OBJECTIVE: Prior work reveals that Enhanced Recovery After Surgery (ERAS) programs decrease opioid use, improve mobilization, and shorten length of stay (LOS) among patients undergoing spine surgery. The impact of ERAS on outcomes by race/ethnicity is unknown. This study examined outcomes by race/ethnicity among neurosurgical patients enrolled in an ERAS program. METHODS: Patients undergoing elective spine or peripheral nerve surgeries at a multi-hospital university health system from April 2017 to November 2020 were enrolled in an ERAS program that involves preoperative, perioperative, and postoperative phases focused on improving outcomes through measures such as specialty consultations for co-morbidities, multimodal analgesia, early mobilization, and wound care education. The following outcomes for ERAS patients were compared by race/ethnicity: length of stay, discharge disposition, complications, readmission, pain level at discharge, and post-operative health rating. We estimated the association between race/ethnicity and the outcomes using linear and logistic regression models adjusting for age, sex, insurance, BMI, comorbid conditions, and surgery type. RESULTS: Among participants (n = 3449), 2874 (83.3%) were White and 575 (16.7%) were Black, Indigenous, and people of color (BIPOC). BIPOC patients had significantly longer mean length of stay compared to White patients (3.8 vs. 3.4 days, p = 0.005) and were significantly more likely to be discharged to a rehab or subacute nursing facility compared to White patients (adjusted odds ratio (95% CI): 3.01 (2.26-4.01), p < 0.001). The complication rate did not significantly differ between BIPOC and White patients (13.7% vs. 15.5%, p = 0.29). BIPOC patients were not significantly more likely to be readmitted within 30 days compared to White patients in the adjusted model (adjusted odds ratio (95% CI): 1.30 (0.91-1.86), p = 0.15) CONCLUSION: BIPOC as compared to White ERAS participants in ERAS undergoing neurosurgical procedures had significantly longer hospital stays and were significantly less likely to be discharged home. ERAS protocols present an opportunity to provide consistent high quality post-operative care, however while there is evidence that it improves care in aggregate, our results suggest significant disparities in outcomes by patient race/ethnicity despite enrollment in ERAS. Future inquiry must identify contributors to these disparities in the recovery pathway.

BACKGROUND: This historical account reviews the course and lasting impact of Dr. Louise Eisenhardt (1891-1967) in neurosurgery. METHOD: The writing of this project was sparked by the discovery of original scientific and bibliographical information about Eisenhardt, testimony on personal relationships, and viewpoints after comprehensive compilation of information. It is a thorough review of literature on Eisenhardt and reflects the scope and depth of these prior works. RESULTS: It begins with the decisive influence of Harvey Cushing's mentorship and academic; follows Eisenhardt's impact on the development of modern neuropathology; discusses the Eisenhardt-Percival-Bailey-Cushing collaboration on gross brain specimens and histological classification of brain tumors; recounts Cushing's creation of a neuropathologist team for the Brain Tumor Registry working asynchronously with the Pathology Department at Peter Bent Brigham Hospital; Eisenhardt's aid in the development of intraoperative analysis of brain tumors; her career as a neuropathologist; her contributions as Editor-in-Chief of the Journal of Neurosurgery; and her preservation of the Brain Tumor Registry at Yale University School of Medicine estimated the largest and most valuable databank of information in the history of medicine. Eisenhardt served as President, Historian, and Secretary-Treasurer of the Harvey Cushing Society, the professional organization now known as the American Association of Neurological Surgeons, and was senior lecturer for members of the Congress of Neurological Surgeons, constituents of NEUROSURGERY Publications. CONCLUSIONS: Our article provides glimpses into the personality of Dr. Louise Eisenhardt and her marked impact on neurosurgery and allied neurosciences.

PURPOSE: Gender is a known social determinant of health (SDOH) that has been linked to neurosurgical outcome disparities. To improve quality of care, there exists a need to investigate the impact of gender on procedure-specific outcomes. The objective of this study was to assess the role of gender on short- and long-term outcomes following resection of meningiomas - the most common benign brain neoplasm of adulthood - between exact matched patient cohorts. MATERIAL AND METHODS: All consecutive patients undergoing supratentorial meningioma resection (n = 349) at a single, university-wide health system over a 6-year period were analyzed retrospectively. Coarsened exact matching was employed to match patients on numerous key characteristics related to outcomes. Primary outcomes included readmission, ED visit, reoperation, and mortality within 30 and 90 days of surgery. Mortality and reoperation were also assessed during the entire follow-up period. Outcomes were compared between matched female and male cohorts. RESULTS: Between matched cohorts, no significant difference was observed in morbidity or mortality at 30 days (p = 0.42-0.75), 90-days (p = 0.23-0.69), or throughout the follow-up period (p = 0.22-0.45). Differences in short-term mortality could not be assessed due to the low number of mortality events. CONCLUSIONS: After matching on characteristics known to impact outcomes and when isolated from other SDOHs, gender does not independently affect morbidity and mortality following meningioma resection. Further research on the role of other SDOHs in this population is merited to better understand underlying drivers of disparity.

BACKGROUND: Transgender people and racial/ethnic minorities separately report poor healthcare experiences. However, little is known about the healthcare experiences of transgender people of color (TPOC), who are both transgender and racial/ethnic minorities. OBJECTIVE: To investigate how TPOC healthcare experiences are shaped by both race/ethnicity and gender identity. DESIGN AND PARTICIPANTS: Semi-structured, in-depth individual interviews (n = 22) and focus groups (2; n = 17 total); all taken from a sample of TPOC from the Chicago area. All participants completed a quantitative survey (n = 39). APPROACH: Interviews and focus groups covered healthcare experiences, and how these were shaped by gender identity and/or race/ethnicity. The interviews and focus groups were audio recorded, transcribed verbatim, and imported into HyperRESEARCH software. At least two reviewers independently coded each transcript using a codebook of themes created following grounded theory methodology. The quantitative survey data captured participants' demographics and past healthcare experiences, and were analyzed with descriptive statistics. KEY RESULTS: All participants described healthcare experiences where providers responded negatively to their race/ethnicity and/or gender identity. A majority of participants believed they would be treated better if they were cisgender or white. Participants commonly cited providers' assumptions about TPOC as a pivotal factor in negative experiences. A majority of participants sought out healthcare locations designated as lesbian, gay, bisexual, and transgender (LGBT)-friendly in an effort to avoid discrimination, but feared experiencing racism there. A minority of participants expressed a preference for providers of color; but a few reported reluctance to reveal their gender identity to providers of their own race due to fear of transphobia. When describing positive healthcare experiences, participants were most likely to highlight providers' respect for their gender identity. CONCLUSIONS: TPOC have different experiences compared with white transgender or cisgender racial/ethnic minorities. Providers must improve understanding of intersectional experiences of TPOC to improve quality of care.

BACKGROUND: Non-syndromic hearing loss (NSHL) is the most common sensory impairment in humans. Until recently its extreme genetic heterogeneity precluded comprehensive genetic testing. Using a platform that couples targeted genomic enrichment (TGE) and massively parallel sequencing (MPS) to sequence all exons of all genes implicated in NSHL, we tested 100 persons with presumed genetic NSHL and in so doing established sequencing requirements for maximum sensitivity and defined MPS quality score metrics that obviate Sanger validation of variants. METHODS: We examined DNA from 100 sequentially collected probands with presumed genetic NSHL without exclusions due to inheritance, previous genetic testing, or type of hearing loss. We performed TGE using post-capture multiplexing in variable pool sizes followed by Illumina sequencing. We developed a local Galaxy installation on a high performance computing cluster for bioinformatics analysis. RESULTS: To obtain maximum variant sensitivity with this platform 3.2-6.3 million total mapped sequencing reads per sample were required. Quality score analysis showed that Sanger validation was not required for 95% of variants. Our overall diagnostic rate was 42%, but this varied by clinical features from 0% for persons with asymmetric hearing loss to 56% for persons with bilateral autosomal recessive NSHL. CONCLUSIONS: These findings will direct the use of TGE and MPS strategies for genetic diagnosis for NSHL. Our diagnostic rate highlights the need for further research on genetic deafness focused on novel gene identification and an improved understanding of the role of non-exonic mutations. The unsolved families we have identified provide a valuable resource to address these areas.
