Necessity of mandatory postoperative intensive care unit management after clipping surgery for unruptured intracranial aneurysms.

OBJECTIVE: Many neurosurgeons routinely perform postoperative intensive care unit (ICU) management after clipping of unruptured intracranial aneurysms (UIAs). However, whether routine postoperative ICU care is necessary remains a clinical question. Therefore, we investigated which factors acted as risk factors that actually required ICU care after microsurgical clipping of unruptured aneurysms. METHODS: We included a total of 532 patients who underwent clipping surgery for UIA between January 2020 and December 2020. The patients were divided into two groups: those who really required ICU care (41 patients, 7.7%) and those who did not (491 patients, 92.3%). A backward stepwise logistic regression model was used to identify factors that were independently associated with ICU care requirement. RESULTS: The mean hospital stay duration and the operation time were significantly longer in the ICU requirement group than in the no ICU requirement group (9.9 ± 10.7 vs. 6.3 ± 3.7 days, p = 0.041), (259.9 ± 128.4 vs. 210.5 ± 46.1 min, p = 0.019). The transfusion rate was significantly higher (p = 0.024) in the ICU requirement group. Multivariable logistic regression analysis identified male sex (odds ratio [OR], 2.34; 95% confidence interval [CI], 1.15-4.76; p = 0.0195), operation time (OR, 1.01; 95% CI, 1.00-1.01; p = 0.0022), and transfusion (OR, 2.35; 95% CI, 1.00-5.51; p = 0.0500) as independent risk factors for requiring ICU care after clipping. CONCLUSIONS: Postoperative ICU management may not be mandatory after clipping surgery for UIAs. Our results suggest that postoperative ICU management may be more required in the male sex, patients with longer operation times, and those who received a transfusion.

NeuroVerse: neurosurgery in the era of Metaverse and other technological breakthroughs.

The tremendous evolution in modern technology has led to a paradigm shift in neurosurgery. The latest advancements such as augmented reality, virtual reality, and mobile applications have been incorporated into neurosurgical practice. NeuroVerse, representing the application of the metaverse in neurosurgery, brings enormous potential to neurology and neurosurgery. Implementation of NeuroVerse could potentially elevate neurosurgical and interventional procedures, enhance medical visits and patient care, and reshape neurosurgical training. However, it is also vital to consider the challenges that may be associated with its implementation, such as privacy issues, cybersecurity breaches, ethical concerns, and widening of existing healthcare inequalities. NeuroVerse adds phenomenal dimensions to the neurosurgical environment for patients, doctors, and trainees, and represents an incomparable advancement in the delivery of medicine. Therefore, more research is needed to encourage widespread use of the metaverse in healthcare, particularly focusing on the areas of morality and credibility. Although the metaverse is expected to expand rapidly during and after the COVID-19 pandemic, it remains to be seen whether it represents an emerging technology that will revolutionize our society and healthcare or simply an immature condition of the future.

The role of messaging services in day-to-day practice in pediatric neurosurgery, advantages of a bubble network, and an international survey.

INTRODUCTION: Messaging services (MS) are used widely worldwide. The implications of MS usage in daily hospital patient care have not been investigated. In this study, we discuss the extensive usage of MS in our Pediatric Neurosurgical Department, introduce our bubble algorithm, and provide additional input from an international survey. METHODS: WhatsApp activity in the department of pediatric neurosurgery at Dana Children's Hospital, Tel Aviv, Israel, was analyzed. We designed a graphic representation of the content of the different conversation bubbles and how they interact. We also described a survey evaluating MS use in daily neurosurgical practice was sent to 25 neurosurgeons around the world. Collected data included details on the usage of MS, the type of information being transferred, and the participants' opinion of the potential risks and benefits of these systems. We began collecting messaging data November 2018, before the COVID pandemic era. We continued to collect data over the course of almost 3 years. RESULTS: We identified a bubble network structure that reflects a logical method of communication between different segments of pediatric neurosurgical care in our institution. Additionally, we analyzed 22 survey responses, received from 14 different countries. The vast majority of centers with "department groups" use messaging services to transfer multimedia files of patient-related data. Nineteen responders believe that MS significantly improve overall patient care. CONCLUSION: MS has revolutionized and improved the patterns of communication in our department. The great benefits of quick, simple access to information strongly outweigh formality and the potential for medicolegal disadvantages (e.g., HIPAA).

COVID-19 Did Not Stop the Rising Tide: Trends in Case Volume Logged by Surgical Residents.

INTRODUCTION: The coronavirus pandemic has profoundly impacted all facets of surgical care, including surgical residency training. The objective of this study was to assess the operative experience and overall case volume of surgery residents before and during the pandemic. METHODS: Using data from the Accreditation Council for Graduate Medical Education annual operative log reports, operative volume for 2015 to 2021 graduates of Accreditation Council for Graduate Medical Education -accredited general, orthopedic, neuro- and plastic surgery residency programs was analyzed using nonparametric Kendall-tau correlation analysis. The period before the pandemic was defined as AY14-15 to AY18-19, and the pandemic period was defined as AY19-20 to AY20-21. RESULTS: Operative data for 8556 general, 5113 orthopedic, 736 plastic, and 1278 neurosurgery residency graduates were included. Between 2015 and 2021, total case volume increased significantly for general surgery graduates (Kendall's tau-b: 0.905, p = 0.007), orthopedic surgery graduates (Kendall's tau-b: 1.000, p = 0.003), neurosurgery graduates (Kendall's tau-b: 0.905, p = 0.007), and plastic surgery graduates (Kendall's tau-b: 0.810, p = 0.016). Across all specialties, the mean total number of cases performed by residents graduating during the pandemic was higher than among residents graduating before the pandemic, though no formal significance testing was performed. Among general surgery residents, the number of cases performed as surgeon chief among residents graduating in AY19-20 decreased for the first time in 5 years, though the overall volume remained higher than the prior year, and returned to prepandemic trends in AY20-21. CONCLUSIONS: Over the past 7 years, the case volume of surgical residents steadily increased. Surgical trainees who graduated during the coronavirus pandemic have equal or greater total operative experience compared to trainees who graduated prior to the pandemic.

The Top 100 Most Cited Neurosurgical Articles on COVID-19: A Bibliometric Analysis.

BACKGROUND: The first case of coronavirus disease 2019 (COVID-19) was reported in December 2019 in Wuhan, China. This study uses a bibliometric analysis of the top 100 most cited neurosurgical COVID-19-related articles to date to identify and determine their characteristics. METHODS: The Scopus library was searched for all published articles on neurosurgery and COVID-19. The main keywords were used for the search "neurosurgery, neurosurgical, and COVID-19". English language articles reporting on neurosurgical aspects during COVID-19 were included in the study. The retrieved top 100 articles were analyzed, and the following characteristics were noted for each article: 1) article title, 2) year of publication, 3) citations, 4) first author, 5) corresponding author, 6) names of other authors, 7) journal name 8) article type, 9) study focus and 10) involvement of the patient. RESULTS: Our search obtained articles published from December 2019 until 29 March 2022. It was observed that 93% of the documents were published in 2020. The top 100 articles have been cited 2649 times in total. The most cited article was "Factors Associated with Surgical Mortality and Complications among Patients with and without Coronavirus Disease 2019 (COVID-19) in Italy" by Doglietto F. et al., published in JAMA Neurology in June 2020, with 124 citations. CONCLUSIONS: This analysis facilitated in making evidence-based clinical decisions and drawing the attention of researchers to identify and contribute to the increasing scientific work by identifying the top 100 most cited neurosurgical COVID-19-related articles published.

Neurosurgery Applicant Perspective of Neurosurgery Residency Websites.

OBJECTIVE: Applicants rely heavily on virtual information in the form of neurosurgery residency websites (NRWs) to better understand a program's culture, faculty, and opportunities. There is a paucity of information regarding the value of NRW on applicant decision making. The advent of the supplemental ERAS application and continuation of virtual interviews may increase the propensity of which applicants use NRW. The objective of our study was to distribute a survey to further understand applicants' perceptions and opinions of NRW, as well as provide future direction for NRW optimization. METHODS: The current study is a single-institution, retrospective survey design. A survey was designed via Qualtrics software to evaluate applicant demographics, resident education, resident recruitment, and future directions. The survey includes the most frequently used variables on NRW. The survey was distributed to neurosurgery applicants who received an interview at the University of Alabama at Birmingham. Data were analyzed using Microsoft Excel. RESULTS: Among the 293 applicants who received a link to the survey, 87/293 (29.7%) completed it. Respondents elected that useful website variables were "resident rotation schedules and hospital locations," "faculty listings and biographies," and "neurosurgery residency websites served as a first impression of a neurosurgery residency program." More than half of the respondents agreed that their rank list would not be the same without an NRW. The most strongly received statement for future directions was "Neurosurgery residency programs will benefit from renovating their residency website." CONCLUSIONS: Our data suggest NRWs play a vital role in resident recruitment and decision making. Residency programs will benefit from this data and may use it to restructure their virtual recruitment tools and discover innovative virtual recruitment strategies. Our team elucidated the most important variables found on NRWs and proposed future directions for their improvement and the virtual application and recruitment process.

Financial fallout from the COVID-19 pandemic:Report from a high-volume academic neurosurgery.

BACKGROUND: The global healthcare system has been overwhelmed by the Coronavirus disease-2019 (COVID-19). In order to mitigate the risk of spread of the virus, most elective surgical procedures have been cancelled especially during the lockdown periods. The purpose of this study was to assess the financial impact of the COVID outbreak due to the supposed reduced workload from our neurosurgery department in 2020. METHODS: Number of neurosurgical procedures (NSP) within the Department of Neurosurgery and their associated estimated income were retrospectively reviewed globally and month wise from administrative records of billing in 2020 and 2019 based on the Diagnosis related group (DRG) and severity of illness (4 levels). RESULTS: Overall, 824 and 818 inpatient surgical procedures were performed in 2019 and 2020 respectively. The total estimate revenue generated from inpatient surgeries was moderately decreased (3%): 9 498 226.41 euros in 2020 versus 9 817 361.65 euros in 2019 without significant difference across DRG (P=0.96) and severity of illness. CONCLUSIONS: Our data suggests a moderate negative impact of the COVID-19 pandemic had on neurosurgical and financial activity. However, a more in-depth medico-economic analysis need to be performed to assess the real financial impact.

A tropical tertiary neurosurgical centre response to COVID-19 pandemic and its effect on neurosurgical practices.

Background: COVID-19 pandemic may decrease the quantum of care for patients with neurosurgical conditions. Objectives: To determine outpatient clinic (OPC) patient load, neurosurgical procedures volume and disease spectrum following the institution of a new care protocol during the ongoing COVID-19 pandemic and compare with previous practice data in our institution. Methods: A monocentric retrospective analysis of all patients requiring neurosurgical care over a 2-year period. Results: There was a 42.4% reduction in OPC attendance and 41.8% reduction in surgical procedures in 2020 compared to 2019. There was >60 percent reduction in the volume of surgery that was done at the onset and peak of the pandemic but this has normalized in November 2020 despite the resurgence of COVID-19, after the institution of a new care protocol. Neurotrauma procedures (29.6%) were the most common neurosurgical operation in 2020 while congenital malformation surgery (37.3%) was the most common procedure performed in 2019. Conclusions: The ongoing COVID-19 pandemic initially led to significant decrease in quantum and spectra of patients who presented at the OPC and for neurosurgical procedures. Instituted local protocol and Teleclinics, if added to clinical care armamentarium, may help to improve on the low patient attendance during pandemics.

Neurosurgical Services in the Northern Zone of Sarawak in Malaysia: The Way Forward Amid the COVID-19 Pandemic.

BACKGROUND: The novel coronavirus disease 2019 (COVID-19) pandemic has set a huge challenge to the delivery of neurosurgical services, including the transfer of patients. We aimed to share our strategy in handling neurosurgical emergencies at a remote center in Borneo island. Our objectives included discussing the logistic and geographic challenges faced during the COVID-19 pandemic. METHODS: Miri General Hospital is a remote center in Sarawak, Malaysia, serving a population with difficult access to neurosurgical services. Two neurosurgeons were stationed here on a rotational basis every fortnight during the pandemic to handle neurosurgical cases. Patients were triaged depending on their urgent needs for surgery or transfer to a neurosurgical center and managed accordingly. All patients were screened for potential risk of contracting COVID-19 prior to the surgery. Based on this, the level of personal protective equipment required for the health care workers involved was determined. RESULTS: During the initial 6 weeks of the Movement Control Order in Malaysia, there were 50 urgent neurosurgical consultations. Twenty patients (40%) required emergency surgery or intervention. There were 9 vascular (45%), 5 trauma (25%), 4 tumor (20%), and 2 hydrocephalus cases (10%). Eighteen patients were operated at Miri General Hospital, among whom 17 (94.4%) survived. Ninety percent of anticipated transfers were avoided. None of the medical staff acquired COVID-19. CONCLUSIONS: This framework allowed timely intervention for neurosurgical emergencies (within a safe limit), minimized transfer, and enabled uninterrupted neurosurgical services at a remote center with difficult access to neurosurgical care during a pandemic.

Randomized Evaluation of Surgery in Elderly with Traumatic Acute SubDural Hematoma (RESET-ASDH trial): study protocol for a pragmatic randomized controlled trial with multicenter parallel group design.

BACKGROUND: The rapidly increasing number of elderly (≥ 65 years old) with TBI is accompanied by substantial medical and economic consequences. An ASDH is the most common injury in elderly with TBI and the surgical versus conservative treatment of this patient group remains an important clinical dilemma. Current BTF guidelines are not based on high-quality evidence and compliance is low, allowing for large international treatment variation. The RESET-ASDH trial is an international multicenter RCT on the (cost-)effectiveness of early neurosurgical hematoma evacuation versus initial conservative treatment in elderly with a t-ASDH METHODS: In total, 300 patients will be recruited from 17 Belgian and Dutch trauma centers. Patients ≥ 65 years with at first presentation a GCS ≥ 9 and a t-ASDH > 10 mm or a t-ASDH < 10 mm and a midline shift > 5 mm, or a GCS < 9 with a traumatic ASDH < 10 mm and a midline shift < 5 mm without extracranial explanation for the comatose state, for whom clinical equipoise exists will be randomized to early surgical hematoma evacuation or initial conservative management with the possibility of delayed secondary surgery. When possible, patients or their legal representatives will be asked for consent before inclusion. When obtaining patient or proxy consent is impossible within the therapeutic time window, patients are enrolled using the deferred consent procedure. Medical-ethical approval was obtained in the Netherlands and Belgium. The choice of neurosurgical techniques will be left to the discretion of the neurosurgeon. Patients will be analyzed according to an intention-to-treat design. The primary endpoint will be functional outcome on the GOS-E after 1 year. Patient recruitment starts in 2022 with the exact timing depending on the current COVID-19 crisis and is expected to end in 2024. DISCUSSION: The study results will be implemented after publication and presented on international conferences. Depending on the trial results, the current Brain Trauma Foundation guidelines will either be substantiated by high-quality evidence or will have to be altered. TRIAL REGISTRATION: Nederlands Trial Register (NTR), Trial NL9012 . CLINICALTRIALS: gov, Trial NCT04648436 .

360° 3D virtual reality operative video for the training of residents in neurosurgery.

OBJECTIVE: Training of residents is an essential but time-consuming and costly task in the surgical disciplines. During the coronavirus disease 2019 pandemic, surgical education became even more challenging because of the reduced caseload due to the increased shift to corona care. In this context, augmented 360° 3D virtual reality (VR) videos of surgical procedures enable effective off-site training through virtual participation in the surgery. The goal of this study was to establish and evaluate 360° 3D VR operative videos for neurosurgical training. METHODS: Using a 360° camera, the authors recorded three standard neurosurgical procedures: a lumbar discectomy, brain metastasis resection, and clipping of an aneurysm. Combined with the stereoscopic view of the surgical microscope, 7- to 10-minute 360° 3D VR videos augmented with annotations, overlays, and commentary were created. These videos were then presented to the neurosurgical residents at the authors' institution using a head-mounted display. Before viewing the videos, the residents were asked to fill out a questionnaire indicating their VR experience and self-assessment of surgical skills regarding the specific procedure. After watching the videos, the residents completed another questionnaire to evaluate their quality and usefulness. The parameters were scaled with a 5-point Likert scale. RESULTS: Twenty-two residents participated in this study. The mean years of experience of the participants in neurosurgery was 3.2 years, ranging from the 1st through the 7th year of training. Most participants (86.4%) had no or less than 15 minutes of VR experience. The overall quality of the videos was rated good to very good. Immersion, the feeling of being in the operating room, was high, and almost all participants (91%) stated that 360° VR videos provide a useful addition to the neurosurgical training. VR sickness was negligible in the cohort. CONCLUSIONS: In this study, the authors demonstrated the feasibility and high acceptance of augmented 360° 3D VR videos in neurosurgical training. Augmentation of 360° videos with complementary and interactive content has the potential to effectively support trainees in acquiring conceptual knowledge. Further studies are necessary to investigate the effectiveness of their use in improving surgical skills.
