Item Embargo An Assessment Study to Determine the Feasibility, Appropriateness, and Usability of Mobile Clinics to Provide Neurosurgery and Neurology Care in Uganda(2023) Mukumbya, BenjaminNeurosurgical and neurological conditions account for a significant disease burden worldwide, with low- and middle-income countries bearing more than 90% of the burden. Uganda is a low-income nation with a high demand for neuro care services but limited access, especially in rural and remote areas. Mobile health clinics, which have proven to be effective in other specialties, could be adapted to provide neurological care in such regions. The objective of this research was to establish the feasibility, appropriateness, and usability of mobile neuro clinics for providing neurological care to people in Uganda's rural and remote communities. Participants who met the inclusion criteria were invited to participate in an education session. Following the education session, the participants participated in an interview session to evaluate the feasibility, appropriateness, and usability of mobile neuro clinics. The education and interview tools were developed using the Consolidated Framework for Implementation Research (CFIR). To weight provider views, a sentiment weighted scale was used, with total aggregate sentiment scores greater than 42 in each CFIR domain indicating high feasibility, acceptability, and usability. All the assessed CFIR domains scored above sentiment score of 49. The implementation process domain (167) received the best overall sentiment score, followed by the implementation climate structure (141), inner setting domain (102), innovation domain (59), and outer setting domain (55). According to the findings of the research, mobile neuro clinics are feasible, appropriate, and usable in Uganda. To achieve the best results, however, careful planning and integration involving stakeholders from conceptualization to execution are required.
Item Embargo Developing a Machine Learning Based Clinical Decision-Making Tool for Traumatic Brain Injury Patients in Moshi, Tanzania(2023) Huo, LilyBackground: Traumatic brain injury (TBI) has a disproportionate burden on low- and middle-income countries (LMICs) and cost-effective and culturally relevant measures are necessary to improve TBI care. This study aims to characterize emergency healthcare providers’ decision making when treating TBI patients, develop a machine learning-based model to predict TBI patient outcome, and conduct a decision curve analysis (DCA) to evaluate model clinical applicability. Methods: This study is twofold: 1) a secondary analysis of a TBI data registry with 4142 patients and 2) a survey examining physicians decision-making in treating 50 TBI patients in real time. Results: Five machine learning models were developed with AUCs ranging from 70.86% (Single C5.0 Ruleset) to 85.67% (Ensemble Model). DCA showed that all models exhibited a greater net benefit over ranges of clinical thresholds. The survey collected information on 50 patients providing insight on tools used by physicians in real-time when treating TBI patients as well as the unmet need patients at KCMC faced. Conclusions: This study is the first to use machine learning modeling and DCA in the context of TBI prognosis in Sub-Saharan Africa. Prognostic models have great potential within the decision-making process for treating TBI patients in LMIC health systems and such utility can be expanded through determining different threshold probabilities for various interventions.
Item Open Access Early Effects of COVID-19 Pandemic on Neurosurgical Training in the United States: A Case Volume Analysis of 8 Programs.(World neurosurgery, 2021-01) Aljuboori, Zaid S; Young, Christopher C; Srinivasan, Visish M; Kellogg, Ryan T; Quon, Jennifer L; Alshareef, Mohammed A; Chen, Stephanie H; Ivan, Michael; Grant, Gerald A; McEvoy, Sean D; Davanzo, Justin R; Majid, Sonia; Durfy, Sharon; Levitt, Michael R; Sieg, Emily P; Ellenbogen, Richard G; Nauta, Haring JObjective
To determine the impact of the 2019 novel coronavirus disease (COVID-19) pandemic on operative case volume in 8 U.S. neurosurgical residency training programs in early 2020 and to survey these programs regarding training activities during this period.Methods
A retrospective review was conducted of monthly operative case volumes and types for 8 residency programs for 2019 and January through April 2020. Cases were grouped as elective cranial, elective spine, and nonelective emergent cases. Programs were surveyed regarding residents' perceptions of the impact of COVID-19 on surgical training, didactics, and research participation. Data were analyzed for individual programs and pooled across programs.Results
Across programs, the 2019 monthly mean ± SD case volume was 211 ± 82; 2020 mean ± SD case volumes for January, February, March, and April were 228 ± 93, 214 ± 84, 180 ± 73, and 107 ± 45. Compared with 2019, March and April 2020 mean cases declined 15% (P = 0.003) and 49% (P = 0.002), respectively. COVID-19 affected surgical case volume for all programs; 75% reported didactics negatively affected, and 90% reported COVID-19 resulted in increased research time. Several neurosurgery residents required COVID-19 testing; however, to our knowledge, only 1 resident from the participating programs tested positive.Conclusions
This study documents a significant reduction in operative volume in 8 neurosurgery residency training programs in early 2020. During this time, neurosurgery residents engaged in online didactics and research-related activities, reporting increased research productivity. Residency programs should collect data to determine the educational impact of the COVID-19 pandemic on residents' operative case volumes, identify deficiencies, and develop plans to mitigate any effects.Item Open Access Fulfilling the Specialist Neurosurgery Workforce Needs in Africa: a SWOT Analysis of Training Programs and Projection Towards 2030(2021) Ukachukwu, Alvan-Emeka KelechiBackground/ObjectivesAfrica has only 1% of the global neurosurgery workforce, despite having 14% of the global population and 15% of the global neurosurgical disease burden. Also, neurosurgical training is hampered by paucity of training institutions, dearth of training faculty, and deficiency of optimal training resources. The study appraises the current specialist neurosurgical workforce in Africa, evaluates the major neurosurgery training programs, and projects the 2030 workforce capacity using current growth trends. Methods The study involved systematic and gray literature search, with quantitative analysis of retrospective data on the neurosurgery workforce, qualitative evaluation of the major neurosurgery training programs for their strength, weaknesses, opportunities, and threats, and projection modeling of the workforce capacity up to year 2030. Results 1,974 neurosurgeons serve 1.3 billion people (density 0.15/100,000; ratio 1:678,740), in Africa, with the majority (1,271; 64.39%) in North Africa. There are 106 specialist neurosurgery training institutions in 26 African countries, with North Africa having 52 (49.05%) of the training centers. Training is heterogenous, with the major programs being the West African College of Surgeons (WACS) - 24 centers across 7 countries, and the College of Surgeons of East, Central and Southern Africa (COSECSA) - 17 centers in 8 countries. At the current linear growth rate of 74.2 neurosurgeons/year or exponential growth rate of 6.81% per annum, Africa will have 2,716 - 3,813 neurosurgeons by 2030, with a deficit of 4,795 - 11,953 neurosurgeons. The continent requires a scale-up of its linear growth rate to 663.4 - 1269.5 neurosurgeons/year, or exponential growth rate to 15.87% - 22.21% per annum to meet its needs. While North African countries will likely meet their 2030 workforce requirements, sub-Saharan African countries will have significant workforce deficits. Conclusion Despite a recent surge in neurosurgery residency training, the current state of Africa’s neurosurgery workforce is dire, and many countries will be unable to meet their workforce requirements by 2030 at current growth trends. A significant scale-up of the neurosurgery workforce is required in order to meet these targets.
Item Open Access Intra-operative hydroxyethyl starch is not associated with post-craniotomy hemorrhage.(Springerplus, 2015) Feix, James A; Peery, C Andrew; Gan, Tong J; Warner, David S; James, Michael L; Zomorodi, Ali; McDonagh, David LBACKGROUND: Intraoperative intravascular volume expansion with hydroxyethyl starch-based colloids is thought to be associated with an increased risk of post-craniotomy hemorrhage. Evidence for this association is limited. Associations between resuscitation with hydroxyethyl starch and risk of repeat craniotomy for hematoma evacuation were examined. METHODS: Using a retrospective cohort of neurosurgical patients at Duke University Medical Center between March 2005 and March 2012, patient characteristics were compared between those who developed post-craniotomy hemorrhage and those who did not. RESULTS: A total of 4,109 craniotomy procedures were analyzed with 61 patients having repeat craniotomy for post-operative hemorrhage (1.5%). The rate of reoperation in the group receiving 6% High Molecular Weight Hydroxyethyl Starch (Hextend(®)) was 2.6 vs. 1.3% for patients that did not receive hetastarch (P = 0.13). The reoperation rate for those receiving 6% hydroxyethyl Starch 130/0.4 (Voluven(®)) was 1.4 vs. 1.6% in patients not receiving Voluven (P = 0.85). CONCLUSIONS: In this retrospective cohort, intra-operative hydroxyethyl starch was not associated with an increased risk of post-craniotomy hemorrhage.Item Open Access 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.(Neurosurgical focus, 2020-05) Asher, Anthony L; Knightly, John; Mummaneni, Praveen V; Alvi, Mohammed Ali; McGirt, Matthew J; Yolcu, Yagiz U; Chan, Andrew K; Glassman, Steven D; Foley, Kevin T; Slotkin, Jonathan R; Potts, Eric A; Shaffrey, Mark E; Shaffrey, Christopher I; Haid, Regis W; Fu, Kai-Ming; Wang, Michael Y; Park, Paul; Bisson, Erica F; Harbaugh, Robert E; Bydon, MohamadThe Quality Outcomes Database (QOD), formerly known as the National Neurosurgery Quality Outcomes Database (N2QOD), was established by the NeuroPoint Alliance (NPA) in collaboration with relevant national stakeholders and experts. The overarching goal of this project was to develop a centralized, nationally coordinated effort to allow individual surgeons and practice groups to collect, measure, and analyze practice patterns and neurosurgical outcomes. Specific objectives of this registry program were as follows: "1) to establish risk-adjusted national benchmarks for both the safety and effectiveness of neurosurgical procedures, 2) to allow practice groups and hospitals to analyze their individual morbidity and clinical outcomes in real time, 3) to generate both quality and efficiency data to support claims made to public and private payers and objectively demonstrate the value of care to other stakeholders, 4) to demonstrate the comparative effectiveness of neurosurgical and spine procedures, 5) to develop sophisticated 'risk models' to determine which subpopulations of patients are most likely to benefit from specific surgical interventions, and 6) to facilitate essential multicenter trials and other cooperative clinical studies." The NPA has launched several neurosurgical specialty modules in the QOD program in the 7 years since its inception including lumbar spine, cervical spine, and spinal deformity and cerebrovascular and intracranial tumor. The QOD Spine modules, which are the primary subject of this paper, have evolved into the largest North American spine registries yet created and have resulted in unprecedented cooperative activities within our specialty and among affiliated spine care practitioners. Herein, the authors discuss the experience of QOD Spine programs to date, with a brief description of their inception, some of the key achievements and milestones, as well as the recent transition of the spine modules to the American Spine Registry (ASR), a collaboration between the American Association of Neurological Surgeons and the American Academy of Orthopaedic Surgeons (AAOS).Item Open Access Results of the AANS membership survey of adult spinal deformity knowledge: impact of training, practice experience, and assessment of potential areas for improved education: Clinical article.(Journal of neurosurgery. Spine, 2014-10) Clark, Aaron J; Garcia, Roxanna M; Keefe, Malla K; Koski, Tyler R; Rosner, Michael K; Smith, Justin S; Cheng, Joseph S; Shaffrey, Christopher I; McCormick, Paul C; Ames, Christopher P; International Spine Study GroupObject
Adult spinal deformity (ASD) surgery is increasing in the spinal neurosurgeon's practice.Methods
A survey of neurosurgeon AANS membership assessed the deformity knowledge base and impact of current training, education, and practice experience to identify opportunities for improved education. Eleven questions developed and agreed upon by experienced spinal deformity surgeons tested ASD knowledge and were subgrouped into 5 categories: (1) radiology/spinopelvic alignment, (2) health-related quality of life, (3) surgical indications, (4) operative technique, and (5) clinical evaluation. Chi-square analysis was used to compare differences based on participant demographic characteristics (years of practice, spinal surgery fellowship training, percentage of practice comprising spinal surgery).Results
Responses were received from 1456 neurosurgeons. Of these respondents, 57% had practiced less than 10 years, 20% had completed a spine fellowship, and 32% devoted more than 75% of their practice to spine. The overall correct answer percentage was 42%. Radiology/spinal pelvic alignment questions had the lowest percentage of correct answers (38%), while clinical evaluation and surgical indications questions had the highest percentage (44%). More than 10 years in practice, completion of a spine fellowship, and more than 75% spine practice were associated with greater overall percentage correct (p < 0.001). More than 10 years in practice was significantly associated with increased percentage of correct answers in 4 of 5 categories. Spine fellowship and more than 75% spine practice were significantly associated with increased percentage correct in all categories. Interestingly, the highest error was seen in risk for postoperative coronal imbalance, with a very low rate of correct responses (15%) and not significantly improved with fellowship (18%, p = 0.08).Conclusions
The results of this survey suggest that ASD knowledge could be improved in neurosurgery. Knowledge may be augmented with neurosurgical experience, spinal surgery fellowships, and spinal specialization. Neurosurgical education should particularly focus on radiology/spinal pelvic alignment, especially pelvic obliquity and coronal imbalance and operative techniques for ASD.Item Open Access Spinal deformity surgery.(Neurosurgery clinics of North America, 2013-04) Ames, Christopher P; Jian, Brian; Shaffrey, Christopher IItem Open Access The TumorCNC: Development and Evaluation of a First-Prototype Automated Tumor Resection Device(2016) Hill, WestinAs technology advances the state of medical imaging, the capabilities of surgical tooling has remained stagnant, contributing to a rift between a surgeon’s ability to perceive and their ability to act. At this point in the evolution of surgical tooling, some level of action must be yielded to robotic control. This thesis describes the development and provides an evaluation of a first-prototype device for automated tumor removal. Specifically, the device combines a unique implementation of a three-dimensional scanner with a steerable cutting laser, enabling both sensing and cutting in a platform that can generate 3D images of relatively smooth surfaces to a precision beyond the ability of a human surgeon to act. This device will be used as a research platform to answer the important questions currently standing in the way of bringing automation into the operating room. This work outlines the foundational development of a device that could provide a significant improvement to patient outcomes and reduce operating costs by a magnitude not yet demonstrated in the field of surgical robotics.
Item Open Access The use of e-consent in surgery and application to neurosurgery: a systematic review and meta-analysis.(Acta neurochirurgica, 2023-11) Mirza, Asfand Baig; Khoja, Abbas Khizar; Ali, Fizza; El-Sheikh, Mustafa; Bibi-Shahid, Ammal; Trindade, Jandira; Rocos, Brett; Grahovac, Gordan; Bull, Jonathan; Montgomery, Alexander; Arvin, Babak; Sadek, Ahmed-RamadanIntroduction
The integration of novel electronic informed consent platforms in healthcare has undergone significant growth over the last decade. Adoption of uniform, accessible, and robust electronic online consenting applications is likely to enhance the informed consent process and improve the patient experience and has the potential to reduce medico-legal ramifications of inadequate consent. A systematic review and meta-analysis was conducted to evaluate the utility of novel electronic means of informed consent in surgical patients and discuss its application to neurosurgical cohorts.Methods
A review of randomised controlled trials, non-randomised studies of health interventions, and single group pre-post design studies in accordance with the PRISMA statement. Random effects modelling was used to estimate pooled proportions of study outcomes. Patient satisfaction with the informed consent process and patients' gain in knowledge were compared for electronic technologies versus non-electronic instruments. A sub-group analysis was conducted to compare the utility of electronic technologies in neurosurgical cohorts relative to other surgical patients in the context of patient satisfaction and knowledge gain.Results
Of 1042 screened abstracts, 63 studies were included: 44 randomised controlled trials (n = 4985), 4 non-randomised studies of health interventions (n = 387), and 15 single group pre-post design studies (n = 872). Meta-analysis showed that electronic technologies significantly enhanced patient satisfaction with the informed consent process (P < 0.00001) and patients' gain in knowledge (P < 0.00001) compared to standard non-electronic practices. Sub-group analysis demonstrated that neurosurgical patient knowledge was significantly enhanced with electronic technologies when compared to other surgical patients (P = 0.009), but there was no difference in patient satisfaction between neurosurgical cohorts and other surgical patients with respect to electronic technologies (P = 0.78).Conclusions
Novel electronic technologies can enhance patient satisfaction and increase patients' gain in knowledge of their surgical procedures. Electronic patient education tools can significantly enhance patient knowledge for neurosurgical patients. If used appropriately, these modalities can shorten and/or improve the consent discussion, streamlining the surgical process and improving satisfaction for neurosurgical patients.
