Comparative Scoping Review of Prenatal Care Resources for Families of Children With Spinal Dysraphism and Hydrocephalus in High-Income Countries and Low- and Middle-Income Countries

BACKGROUND AND OBJECTIVES

Low- and middle-income countries (LMICs) face higher incidences and burdens of care for neural tube defects (NTDs) and hydrocephalus compared with high-income countries (HICs), in part due to limited access to neurosurgical intervention. In this scoping review, we aim to integrate studies on prenatal care, counseling, and surgical management for families of children with spinal dysraphism and hydrocephalus in LMICs and HICs.

METHODS

PubMed, Embase, Global Index Medicus, and Web of Science electronic databases were searched for English language articles pertaining to prenatal care, counseling, and surgical management for families of children with spinal dysraphism and hydrocephalus in HICs and LMICs. Identified abstracts were screened for full-text review. Studies meeting inclusion criteria were reviewed in full and analyzed.

RESULTS

Seventy studies met the inclusion criteria. Twelve studies (16.9%) were conducted in HICs only, 50 studies (70.4%) were conducted in LMICs only, and 9 studies (12.7%) encompassed both. On thematic analysis, seven underlying topics were identified: epidemiology, folate deficiency and supplementation/fortification, risk factors other than folate deficiency, prenatal screening, attitudes and perceptions about NTDs and their care, surgical management, and recommendations for guideline implementation.

CONCLUSION

NTDs have become a widely acknowledged public health problem in many LMICs. Prenatal counseling and care and folate fortification are critical in the prevention of spinal dysraphism. However, high-quality, standardized studies reporting their epidemiology, prevention, and management remain scarce. Compared with NTDs, research on the prevention and screening of hydrocephalus is even further limited. Future studies are necessary to quantify the burden of disease and identify strategies for improving global outcomes in treating and reducing the prevalence of NTDs and hydrocephalus. Surgical management of NTDs in LMICs is currently limited, but pediatric neurosurgeons may be uniquely equipped to address disparities in the care and counseling of families of children with spinal dysraphism and hydrocephalus.

Pediatric brain tumors in sub-Saharan Africa: a systematic review and meta-analysis

OBJECTIVE

Brain tumors are a global problem, leading to higher cancer-related morbidity and mortality rates in children. Despite the progressive though slow advances in neuro-oncology care, research, and diagnostics in sub-Saharan Africa (SSA), the epidemiological landscape of pediatric brain tumors (PBTs) remains underestimated. This study aimed to systematically analyze the distribution of PBT types in SSA.

METHODS

Ovid Medline, Global Index Medicus, African Journals Online, Google Scholar, and faculty of medicine libraries were searched for literature on PBTs in SSA published before October 29, 2022. A proportional meta-analysis was performed.

RESULTS

Forty-nine studies, involving 2360 children, met the inclusion criteria for review; only 20 (40.82%) were included in the quantitative analysis. South Africa and Nigeria were the countries with the most abundant data. Glioma not otherwise specified (NOS) was the common PBT in the 4 SSA regions combined. However, medulloblastoma was more commonly reported in Southern SSA (p = 0.01) than in other regions. The prevalence and the overall pooled proportion of the 3 common PBTs was estimated at 46.27% and 0.41 (95% CI 0.32-0.50, 95% prediction interval [PI] 0.11-0.79), 25.34% and 0.18 (95% CI 0.14-0.21, 95% PI 0.06-0.40), and 12.67% and 0.12 (95% CI 0.09-0.15, 95% PI 0.04-0.29) for glioma NOS, medulloblastoma, and craniopharyngioma, respectively. Sample size moderated the estimated proportion of glioma NOS (p = 0.02). The highest proportion of craniopharyngiomas was in Western SSA, and medulloblastoma and glioma NOS in Central SSA.

CONCLUSIONS

These findings provide insight into the trends of PBT types and the proportion of the top 3 most common tumors across SSA. Although statistical conclusions are difficult due to the inconsistency in the data, the study identifies critical areas for policy development and collaborations that can facilitate improved outcomes in PBTs in SSA. More accurate epidemiological studies of these tumors are needed to better understand the burden of the disease and the geographic variation in their distribution, and to raise awareness in their subsequent management.

Asleep-awake-asleep versus hypnosis for low-grade glioma surgery: long term follow-up outcome

BACKGROUND

Hypnosis-aided craniotomy is a safe alternative to standard asleep-awake-asleep (AAA) surgery in glioma surgery. The impact of these two anesthetic methods on tumor prognosis has never been assessed.

OBJECTIVE

This study aimed to evaluate the possible impact of the type of sedation (i.e., hypnosedation vs. standard sedation) on postoperative outcomes in awake surgery for gliomas.

METHODS

Adult patients who underwent awake surgery for a diffuse glioma, excluding glioblastomas, between May 2011 and December 2019 at the authors' institution were included in the analysis. Pearson Chi-square, Fisher exact, and Mann-Whitney U tests were used for inferential analyses.

RESULTS

Sixty-one (61) patients were included, thirty-one were female (50.8 %), and the mean age was 41.8 years (SD = 11.88). Most patients had IDH mutated tumors (n = 51; 83.6%). Twenty-six patients (42.6%) were hypnosedated while 35 (57.4%) received standard AAA procedure. The overall median follow-up time was 48 months (range: 10 months-120 months). Our results did not identify any significant difference between both techniques in terms of extent of resection (sub-total resection >95% rates were 11.48% vs. 8.20%, OR = 2.2, 95% CI = 0.62-8.44; P = 0.34) and of overall survival (87.5% of patients in the AAA surgery group reach 9 years OS vs. 79% in the hypnosis cohort, cHR = 0.85, 95% CI = 0.12-6.04; P = 0.87).

CONCLUSION

Hypnosis for awake craniotomy is rarely proposed although it is a suitable alternative to standard sedation in awake craniotomy for LGGs, with similar results in terms of extent of resection or survival.

The World Neurosurgery Global Champions Program: First-Year Experience of a Model Initiative for Reducing Disparities in Global Neurosurgical Literature

OBJECTIVE

Most surgical journals are published in English, representing a challenge for researchers from non-Anglophone countries. We describe the implementation, workflow, outcomes, and lessons learned from the World Neurosurgery Global Champions Program (GCP), a novel journal-specific English language editing program for articles rejected because of poor English grammar or usage.

METHODS

The GCP was advertised via the journal website and social media. Applicants were selected to be a reviewer for the GCP if they demonstrated English proficiency on writing samples supplied in their application. The demographics of GCP members and characteristics and outcomes of articles edited by the GCP during its first year were reviewed. Surveys of GCP members and authors who used the service were conducted.

RESULTS

Twenty-one individuals became part of the GCP, representing 8 countries and 16 languages apart from English. A total of 380 manuscripts were peer-reviewed by the editor-in-chief, who determined these manuscripts to have potentially worthwhile content but needed to be rejected due to poor language. The authors of these manuscripts were informed of the existence of this language assistance program. Forty-nine articles (12.9%) were edited by the GCP in 41.6 ± 22.8 days. Of 40 articles resubmitted to World Neurosurgery, 24 (60.0%) were accepted. GCP members and authors understood the purpose and workflow of the program and recognized improvements in article quality and the probability of acceptance through their participation.

CONCLUSION

The World Neurosurgery Global Champions Program mitigated a critical barrier to publication in an English language journal for authors from non-Anglophone countries. This program promotes research equity by providing a free, largely medical student and trainee operated, English language editing service. This model or a similar service can be replicated by other journals.

Artificial Intelligence in Medical Imaging for Cholangiocarcinoma Diagnosis: A Systematic Review with Scientometric Analysis

INTRODUCTION

Artificial intelligence (AI), by means of computer vision in machine learning, is a promising tool for cholangiocarcinoma (CCA) diagnosis. The aim of this study was to provide a comprehensive overview of AI in medical imaging for CCA diagnosis.

METHODS

A systematic review with scientometric analysis was conducted to analyze and visualize the state-of-the-art of medical imaging to diagnosis CCA.

RESULTS

Fifty relevant articles, published by 232 authors and affiliated with 68 organizations and 10 countries, were reviewed in depth. The country with the highest number of publications was China, followed by the United States. Collaboration was noted for 51 (22.0%) of the 232 authors forming 5 clusters. Deep learning algorithms with convolutional neural networks (CNN) were the most frequently used classifiers. The highest performance metrics were observed with CNN-cholangioscopy for diagnosis of extrahepatic CCA (accuracy 94.9%; sensitivity 94.7%; and specificity 92.1%). However, some of the values for CNN in CT imaging for diagnosis of intrahepatic CCA were low (AUC 0.72 and sensitivity 44%).

CONCLUSION

Our results suggest that there is increasing evidence to support the role of AI in the diagnosis of CCA. CNN-based computer vision of cholangioscopy images appears to be the most promising modality for extrahepatic CCA diagnosis. Our social network analysis highlighted an Asian and American predominance in the research relational network of AI in CCA diagnosis. This discrepancy presents an opportunity for coordination and increased collaboration, especially with institutions located in high CCA burdened countries.

Historical determinants of neurosurgical inequities in Africa and the African diaspora: A review and analysis of coloniality

The movement to decolonize global health challenges clinicians and researchers of sub-disciplines, like global neurosurgery, to redefine their field. As an era of racial reckoning recentres the colonial roots of modern health disparities, reviewing the historical determinants of these disparities can constructively inform decolonization. This article presents a review and analysis of the historical determinants of neurosurgical inequities as understood by a group of scholars who share Sub-Saharan African descent. Vignettes profiling the colonial histories of Cape Verde, Rwanda, Cameroon, Ghana, Brazil, and Haiti illustrate the role of the colonial legacy in the currently unmet need for neurosurgical care in each of these nations. Following this review, a bibliographic lexical analysis of relevant terms then introduces a discussion of converging historical themes, and practical suggestions for transforming global neurosurgery through the decolonial humanism promulgated by anti-racist practices and the dialogic frameworks of conscientization.

Understanding the Ghanaian Neurosurgical Literature: A Scoping Review and Bibliometric Analysis

BACKGROUND

Research serves to bolster clinical neurosurgery by critically assessing various disease pathologies, while identifying important challenges and opportunities. However, there is limited information on the landscape of the Ghanaian neurosurgical literature.

METHODS

A scoping review and bibliometric analysis was conducted in accordance with PRISMA guidelines. PubMed, Embase, Global Index Medicus, and Web of Science electronic databases were searched from inception until December 21, 2021 for English language articles about neurosurgery in Ghana.

RESULTS

927 articles were identified and 66 were ultimately included in the analysis. A majority of them, 42.4%, were retrospective cohort studies, with 62.1% published after 2010. There were no randomized controlled or basic science studies. Most articles were published in the West African Journal of Medicine (24.2%) and non-infectious/non-traumatic spinal pathology was the most commonly discussed topic (22.7%); 66.7% of articles included only authors affiliated with Ghanaian institutions, and international collaborators frequently originated from the United States (15.9%). Only 22.7% of the manuscripts reported a funding source. Commonly reported challenges included limited sample sizes, delays in diagnosis and treatment, and lack of proper diagnostic tools and specialized care.

CONCLUSIONS

This review revealed that while the Ghanaian academic neurosurgery output has been increasing over time, these have been limited to cohort studies largely assessing spine pathology. The Ghanaian neurosurgical research environment may be bolstered by an increase in research funding, the establishment of longitudinal clinical databases, training in research methodology, increased incentives for researchers, strengthening of research collaborative networks, and increased engagement of neurosurgical trainees in research.

The state of surgery, obstetrics, trauma, and anaesthesia care in Ghana: a narrative review

Background

Conditions amenable to surgical, obstetric, trauma, and anaesthesia (SOTA) care are a major contributor to death and disability in Ghana. SOTA care is an essential component of a well-functioning health system, and better understanding of the state of SOTA care in Ghana is necessary to design policies to address gaps in SOTA care delivery.

Objective

The aim of this study is to assess the current situation of SOTA care in Ghana.

Methods

A situation analysis was conducted as a narrative review of published scientific literature. Information was extracted from studies according to five health system domains related to SOTA care: service delivery, workforce, infrastructure, finance, and information management.

Results

Ghanaians face numerous barriers to accessing quality SOTA care, primarily due to health system inadequacies. Over 77% of surgical operations performed in Ghana are essential procedures, most of which are performed at district-level hospitals that do not have consistent access to imaging and operative room fundamentals. Tertiary facilities have consistent access to these modalities but lack consistent access to oxygen and/or oxygen concentrators on-site as well as surgical supplies and anaesthetic medicines. Ghanaian patients cover up to 91% of direct SOTA costs out-of-pocket, while health insurance only covers up to 14% of the costs. The Ghanaian surgical system also faces severe workforce inadequacies especially in district-level facilities. Most specialty surgeons are concentrated in urban areas. Ghana’s health system lacks a solid information management foundation as it does not have centralized SOTA databases, leading to incomplete, poorly coded, and illegible patient information.

Conclusion

This review establishes that surgical services provided in Ghana are focused primarily on district-level facilities that lack adequate infrastructure and face workforce shortages, among other challenges. A comprehensive scale-up of Ghana’s surgical infrastructure, workforce, national insurance plan, and information systems is warranted to improve Ghana’s surgical system.

Peer mentorship to build research capacity among members of the International Student Surgical Network (InciSioN): a proof of concept study

BACKGROUND

International Student Surgical Network (InciSioN) is the largest student and trainee global surgery interest group worldwide and its members have contributed significantly to global surgery research. The InciSioN Research Capacity-Building (IReCaB) program aimed to enhance the research skills and confidence of participants via a peer mentorship model.

METHODS

After an open call to members of InciSioN to enroll, participants' knowledge of research methods and the process was evaluated through a test to assign mentor and mentee roles, with mentors being those who scored ≥ 20/25. Mentors then delivered a series of four webinars to help disseminate research methodology to mentees. Finally, mentees were tested on their knowledge of research and their satisfaction with the program was also evaluated.

RESULTS

Fifty-two participants, mostly from LMICs (n = 23/52, 44.2%) were enrolled, and 36 completed the program. There was a significant improvement in the proportion of questions answered correctly on the post-program test (R = 0.755, p < 0.001). Post-IReCaB test scores were greater than pre-IReCaB scores (p < 0.001). The difference in confidence after the course was also significant (p < 0.001). IReCaB participants successfully designed, implemented, and published an international cross-sectional study.

CONCLUSION

This study showed improvements in participants' understanding of theoretical components of scientific research. We offer a model for research capacity building that can be implemented, modeled, and further refined by similar organizations with academic research goals.

Evidence-Driven Policies for Sustainably Scaling Up Surgical Task-Sharing in Malawi Comment on "Improving Access to Surgery Through Surgical Team Mentoring - Policy Lessons From Group Model Building With Local Stakeholders in Malawi"

This commentary discusses an article by Broekhuizen et al which assesses policy options for scaling up the SURG-Africa surgical team mentoring program in Malawi to increase access to surgical care. In modeling these scenarios, the authors assess the cost of scaling up surgical teams mentoring and the impacts of scaling the program on district hospitals (DHs) and central hospitals (CHs). The additional costs borne by DHs when increasing surgical volume remains a significant issue identified by the authors and could ultimately determine the success of the program. The piece indirectly advocates for an increased role for task-shifting. The Ministry of Health of Malawi will have to ensure the appropriate governance and regulatory processes are in place to maintain quality and accountability.

Factors Associated with Adverse Outcomes in Cameroonian Patients with Traumatic Brain Injury: A Cross-Sectional Study

BACKGROUND

The burden of traumatic brain injury (TBI) disproportionately affects low- and middle-income countries. In Cameroon, the estimated annual incidence rate is 572 cases per 100,000 people. This study investigated factors associated with adverse outcomes in the management of Cameroonian patients with TBI.

METHODS

This cross-sectional study included all patients with TBI treated between January 1 and December 31, 2018, at 2 Cameroonian referral hospitals. Sociodemographic and clinical data were extracted from patient charts and admission registries and analyzed with SPSS v.26. Independent t tests, odds ratios, and cumulative mortality hazard rates were computed. A P-value <0.05 was considered statistically significant. Also, binomial regression analyses were calculated.

RESULTS

One hundred seventy-one patients aged 38.63 ± 20.46 years old received treatment for TBI. Most patients were male (78.9%), Cameroonian (98.2%), from urban areas (75.4%), and uninsured (88.8%). The average admission length was 11.23 ± 10.71 days, during which 27.5% of patients received surgical treatment while 72.5% received non-surgical (conservative) management. From postdischarge day 12 onwards, surgically-treated patients had a greater cumulative mortality hazard rate than conservatively-treated patients. By 28 days postdischarge, 66.1% of patients had recovered completely [Glasgow Outcome Scale (GOS) = 5], 23.4% had a disability (GOS = 2-4), and 10.5% expired (GOS = 1). Complete recovery was associated with the absence of severe TBI (B = -1.42, standard error [SE] = 0.52, P = 0.006), disability was associated with increased injury-to-admission delay (B = -1.27, SE = 0.48, P = 0.009), and death was associated with severe TBI (B = 3.16, SE = 0.73, P < 0.001).

CONCLUSIONS

We identified factors associated with unfavorable outcomes among Cameroonian patients with TBI. These results can inform triage and referral practices and aid policymakers in developing context-specific prehospital guidelines.

Tranexamic acid for patients with aneurysmal subarachnoid hemorrhage: a systematic review and meta-analysis of 2991 patients

OBJECTIVE

We aimed to synthesize evidence from published clinical trials on the efficacy and safety of tranexamic acid (TXA) administration in patients with aneurysmal subarachnoid hemorrhage (aSAH).

METHODS

We followed the standard methods of the Cochrane Handbook of Systematic Reviews for interventions and the PRISMA statement guidelines 2020 when conducting and reporting this study. A computer literature search of PubMed, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials was conducted from inception until 1 January 2022. We selected observational studies and clinical trials comparing TXA versus no TXA in aSAH patients. Data of all outcomes were pooled as the risk ratio (RR) with the corresponding 95% confidence intervals in the meta-analysis models.

RESULTS

Thirteen studies with a total of 2991 patients were included in the analysis. TXA could significantly cut the risk of rebleeding (RR 0.56, 95% CI 0.44 to 0.72) and mortality from rebleeding (RR 0.60, 95% CI 0.39 to 0.92, p = 0.02). However, TXA did not significantly improve the overall mortality, neurological outcome, delayed cerebral ischemia, or hydrocephalus (all p > 0.05). In terms of safety, no significant adverse events were reported. No statistical heterogeneity or publication bias was found in all outcomes.

CONCLUSION

In patients with aSAH, TXA significantly reduces the incidence of rebleeding and mortality from rebleeding. However, current evidence does not support any benefits in overall mortality, neurological outcome, delayed cerebral ischemia, or hydrocephalus.

Profiling African Health Journals: A Bibliometric Study

Objectives: This study aimed to map out African health journals using publicly-available information on major databases.

Methods: The authors searched the African Journals Online Library (AJOL) and Scientific Journal Rankings (SJR) databases from their inception in 1998 and 1996 respectively to 17 October 2020, and identified African health journals. The authors extracted data on journal scope, PubMed indexation, open-access status, publishing fees, Journal Publishing Practices and Standards rating and bibliometrics. The data were compared with health journals from other regions using the Chi-square test and odds ratio.

Results: AJOL had 173 health journals registered on its database. One hundred (57.8%) journals were actively publishing. Fifty-seven (32.9%) had a 1-star Journal Publishing Practices and Standards rating and 4 (2.3%) had 2-star ratings. 112 (64.7%) had no star rating. The journal scope spanned all aspects of health. Few health journals were PubMed (n = 20) or SJR (n = 22) indexed. On average, African journals had lower total publications (median [IQR]: 52.0 [29.0–74.8] vs. 140.0 [75.8–272.5]), total references (55.0 [19.5–74.8] vs. 160.0 [42.0–519.8]), and H-index (12.2 [5.0–14.0] vs. 39.1 [10.0–53.0]) (P=0.01) compared to other regions.

Conclusion: African health journals face unique challenges that require targeted interventions.

Barriers Encountered Toward Pursuing a Neurosurgical Career: A Cross-Sectional Study Among Medical Students, Interns, and Junior Doctors in Africa

BACKGROUND

Africa has an increased burden of neurosurgical diseases with an estimate of 1,986,392 neurosurgical cases, 108,824 neurosurgical case capacity, and 1,877,568 case deficits yearly. Literature suggests that about 8420 neurosurgeons are needed to fill this vast gap. The main objective of this study is to elucidate barriers encountered in pursuing neurosurgery training in the African context.

METHODS

A cross-sectional electronic survey, developed in English and subsequently translated into French, was utilized. This was disseminated among medical students, medical interns, and junior doctors in all 5 African regions.

RESULTS

A total of 491 responses were received from the following 5 African regions: West Africa (30.5%), East Africa (30.3%), Central Africa (18.1%), North Africa (11.8%), and Southern Africa (9.2%). Of the participants, 55.2% were men and 44.8% were women. Seventy-six percent of respondents were aware of the neurosurgery deficit in Africa. Barriers to pursuing neurosurgery included discouragement from others over lack of an "ideal personality" trait, culture/cultural beliefs as related to gender roles, lack of mentorship, inadequate neurosurgical training opportunities, poor health infrastructure for neurosurgical practice in Africa, poor patient outcomes, and challenges with work/life balance were some of the barriers highlighted to pursuing neurosurgical career on the continent.

CONCLUSION

Even with its robust population growth, Africa is not producing enough neurosurgeons to meet the demands of the population due to several barriers. Delineating these challenges and barriers represents an important step in developing sustainable mechanisms for recruitment, training, mentorship, and support of burgeoning African neurosurgeons.

State of African Neurosurgical Education: An Analysis of Publicly Available Curricula

BACKGROUND

Africa bears more than 15% of the global burden of neurosurgical disease; however, it has the lowest neurosurgical workforce density worldwide. The past decade has seen an increase in neurosurgery residency programs on the continent. It is unclear how these residency programs are similar or viable. This study highlights the current status and interdepartmental and regional differences, with the main objective of offering a template for improving the provision of neurosurgical education on the continent.

METHODS

PubMed and Google Scholar were searched using keywords related to "neurosurgery," "training," and "Africa" from database inception to October 13, 2021. The residency curricula were analyzed using a standardized and validated medical education curriculum viability tool.

RESULTS

Curricula from 14 African countries were identified. The curricula differed in resident recruitment, evaluation mode and frequency, curriculum content, and length of training. The length of training varied from 4 to 8 years, with a mean of 6 years. The Eastern African region had the highest number of examinations, with a mean of 8.5. Few curricula had correlates of viability: ensuring that the instructors are competent (64.3%), prioritization of faculty development (64.3%), faculty participation in decision making (64.3%), prioritization of resident support services (50%), creating a conducive environment for quality education (42.9%), and addressing student complaints (28.6%).

CONCLUSIONS

There are significant differences in the African postgraduate neurosurgical education curriculum warranting standardization. This study identifies areas of improvement for neurosurgical education in Africa.

820 Management and Outcomes of Traumatic Paediatric Spinal Cord Injuries in Low- and Middle-Income Countries: A Scoping Review

Introduction

Traumatic spinal cord injury (TSCI) is a subset of neurotrauma, which is a significant contributor to global trauma mortality and morbidity in children. The management and outcomes of paediatric TSCI in low- and middle-income countries (LMICs) is unknown. We conducted a scoping review to characterise the methods of management and outcomes of TSCI in LMICs.

Method

MEDLINE, EMBASE, and Global Index Medicus were searched from database inception to February 15, 2021. Studies reporting management or outcomes of paediatric TSCI in LMICs were included. Pooled statistics were calculated using measures of central tendency and spread.

Results

A total of 1171 studies were identified, of which, five were included. A total of 212 patients were included in our review with age of participants ranging from 2.5 to 18 years old (mean = 15.4 years). Most patients were male (n=162/212, 76.4%, 95% confidence interval [CI] = 70.7–82.1%). The commonest cited cause of injury was falls (n=104/212, 49.1%, 95% CI = 42.3–55.8%). The most common level of injury was cervical (n=83/212, 39.2%, 95 CI% = 32.6–45.7%). The majority of patients underwent surgery (n=134/212, 63.2%, 95 CI% = 56.7–69.7%). The extent of injury was quantified and classified using the ASIA chart in only one paper. Long-term management data was not present in any of the included studies.

Conclusions

There is a scarcity of published studies reporting the management and outcome of paediatric TSCI in LMICs. There is insufficient data to be compared and to draw a strong conclusion. This hinders the development of guidelines to inform best practice.

In-hospital mortality rates, complication rates, length of stay, and total costs of >14,000 chronic subdural hematomas treated in the U.S. between 2016 and 2020: Query of the premier health-care database

Background:

With the drastically aging population in the U.S., chronic subdural hematomas (cSDHs) are projected to represent the most common neurosurgical diagnosis requiring treatment within the next two decades. There is lack of contemporary outcome data in patients treated for nontraumatic and nonacute subdural hematoma. We aim to portray current mortality rates, complication rates, length of stay, and costs associated with inpatient cSDH care.

Methods:

The Premier Health-care Database, Premier Inc., Charlotte/NC was queried for encounters October 2016–December 2020 with the ICD-10 diagnoses of nontraumatic nonacute subdural hematoma as the principal diagnosis among patients age ≥40 years. Per database in-hospital mortality is defined as mortality in an inpatient who is not discharged. Complications represent medical conditions not present on admission that affects mortality, length of stay, and costs within the database.

Results:

The query identified 14,136 inpatient encounters. Between October 2016 and December 2020, in-hospital mortality rates averaged 10.9% in the medical group (MG) and 3.6% in the surgical group (SG) (P < 0.001). Complication rates averaged between 8.9 % in the MG and 19.9% in the SG (P < 0.001). LOS averaged 3.0 days in the MG and 5.7 days in the SG (P < 0.001). Total costs averaged $ 10,233 in the MG and $ 26,658 in the SG.

Conclusion:

The standardized outcomes presented represent an objective benchmark of contemporary cSDH treatment outcomes in the U.S. With the projected substantial increase of cSDH cases within the next decades, new treatment strategies such as middle meningeal embolization need to be explored and outperform current outcome metrics.

Vulnerability of African Neurosurgery to Predatory Journals: An Electronic Survey of Aspiring Neurosurgeons, Residents, and Consultants

BACKGROUND

Predatory journals (PJs) publish research with little to no rigorous peer review in exchange for money. It is unclear what proportion of researchers is vulnerable to PJs and which factors are associated with vulnerability. The aim of this study was to evaluate the vulnerability of African neurosurgery researchers to PJs and identify their correlates.

METHODS

A 3-part electronic survey in English and French versions was distributed via social media to African consultants and trainees from November 1 to December 1, 2021. Bivariable relationships were evaluated with χ² test, Mann-Whitney U test, Spearman ρ correlation, odds ratios, and 95% confidence intervals. A P value < 0.05 was considered statistically significant.

RESULTS

There were 101 respondents to the survey (response rate 56.1%). Respondents had mean age of 34.9 years, 82.2% were male (n = 83), 38.6% were consultant neurosurgeons (n = 39), and 33.7% were from Central Africa (n = 34). Of respondents, 66 had published ≥ 1 articles in the past, and 13 had published at least 1 article in a PJ. A PJ had contacted 34 respondents via e-mail, and 8 respondents had reviewed articles for a PJ. The Think. Check. Submit initiative and Beall's list were familiar to 19 and 13 respondents, respectively. Publication in PJs was correlated with the respondent's age (R = 0.23, P = 0.02) and total scholarly output (R = 0.38, P < 0.01).

CONCLUSIONS

Young African neurosurgery researchers are vulnerable to PJs primarily because they are not familiar with the concept of PJs or how to identify them.

Adult brain tumors in Sub-Saharan Africa: A scoping review

BACKGROUND

Sub-Saharan African (SSA) neuro-oncologists report high workloads and challenges in delivering evidence-based care; however, these reports contrast with modeled estimates of adult neuro-oncology disease burden in the region. This scoping review aimed to better understand the reasons for this discrepancy by mapping out the SSA adult brain tumor landscape based on published literature.

METHODS

Systematic searches were conducted in OVID Medline, Global Index Medicus, African Journals Online, Google Scholar, and faculty of medicine libraries from database inception to May 31 st, 2021. The results were summarized quantitatively and narratively. English and French peer-reviewed articles were included (title, abstract, and full text).

RESULTS

Of the 819 records identified, 119 articles by 24 SSA countries (42.9%) were included in the final review. Odeku published the first article in 1967, and nine of the ten most prolific years were in the 21 st century. The greatest contributing region was Western Africa (n=58, 48.7%) led by Nigeria (n=37, 31.1%). Central Africa had fewer articles published later than the other SSA regions (p=0.61). Most studies were non-randomized (n=75, 63.0%) and meningiomas (n=50, 42.0%) were the most common brain tumors reported. Less than 30 studies reported on adjuvant treatment or patient outcomes.

CONCLUSIONS

Most publications were hospital-based, and there was significant heterogeneity in the quality of evidence and reporting. This study highlights the need for rapid and sustainable investments and brain tumor research capacity in SSA.

The Neurology and Neurosurgery Interest Group (NANSIG)-ten years of cultivating interest in clinical neurosciences

Collaboration and successful teamworking are important components of clinical practise, and these skills should be cultivated early in medical school. The breadth of current medical school curricula means that students often have limited exposure to clinical neurosciences. Since its inception in 2009, the Neurology and Neurosurgery Interest Group (NANSIG) has become a national (UK and Republic of Ireland) example of student and junior doctor synergistic collaboration to deliver educational materials, research, conferences, seminars and workshops, as well as advocating for diversity in this field. Recently, it has expanded to incorporate an international audience and cater for a larger group of young medical professionals. The organisation has overcome numerous challenges and is constantly innovating new approaches to harness the necessary knowledge, skills and network to succeed in a career in neurosciences, neurology and neurosurgery. This article summarises the initiatives undertaken by the group over its first 10 years of existence and its organisational structure, as well as its future plans.

Hand grenade blast injuries in the Eastern Democratic Republic of Congo: a case series of 38 patients

Introduction

The armed conflict in the Kivu province of the Democratic Republic of Congo has caused close to 12,000 deaths. One of the most lethal weapons in armed conflicts is the high explosive hand grenade. The study aimed to describe the epidemiology, presentation, and outcomes of hand grenade blast injuries (HGBI) in the Kivu province.

Methods

In this case series, the authors present 2017 to 2020 HGBI admissions at a Congolese trauma center. Measures of central tendency and spread were computed for continuous data. Complication and mortality rates were equally computed. Admission-to-discharge data were disaggregated by the body part injured and by complication status and visualized using time-to-event curves.

Results

Thirty-eight HGBI patients aged 31.4 (range 17–56) years were included in the study. Twenty-six (68.4%) were male and the patients were admitted 1.8 days post-injury on average. The patients were hemodynamically stable at admission; 84.2% received the antitetanic vaccine, 21.1% received broad-spectrum antibiotics, and all were debrided (100.0%). The complication rate was 13.2%, and the most common complication was anemia (7.9%). In addition, the mortality rate was 2.6%. The median admission-to-discharge time was 17.0 (range 4–71) days, and it was prolonged in patients with lower extremity injuries (23.0 days).

Conclusion

HGBIs cause avertable death and disability in the Kivu regions. These data suggest that the burden of HGBIs can be reduced with appropriate preventive and health systems strengthening interventions.

Public awareness, knowledge of availability, and willingness to use neurosurgical care services in Sub-Saharan Africa: A cross-sectional study

Introduction

Low- and middle-income countries bear the majority of neurosurgical disease burden and patients face significant barriers to seeking, reaching, and receiving care. We aimed to understand barriers to seeking care among adult Africans by evaluating the public perception, knowledge of availability, and readiness to use neurosurgical care services.

Methods

An e-survey was distributed among African adults who are not in the health sector or pursuing a health-related degree. Chi-square test and ANOVA were used for bivariate analysis and the alpha value was set at 0.05. Odds ratios and their 95% confidence intervals were calculated.

Results

Six hundred and sixty-two adults from 16 African countries aged 25.4 (95% CI: 25.0, 25.9) responded. The majority lived in urban settings (90.6%) and were English-speaking (76.4%) men (54.8%). Most respondents (76.3%) could define neurosurgery adequately. The most popular neurosurgical diseases were traumatic brain injury (76.3%), congenital brain and spine diseases (67.7%), and stroke (60.4%). Unwillingness to use or recommend in-country neurosurgical services was associated with rural dwelling (β = -0.69, SE = 0.31, P = 0.03), lack of awareness about the availability of neurosurgeons in-country (β = 1.02, SE = 0.20, P<0.001), and believing neurosurgery is expensive (β = -1.49, SE = 0.36, P<0.001).

Conclusion

Knowledge levels about neurosurgery are satisfactory; however, healthcare-seeking is negatively impacted by multiple factors.

Firearm injuries among children due to the Kivu conflict from 2017 to 2020: A hospital-based retrospective descriptive cohort study

INTRODUCTION

Firearm-related injuries are deadly but avoidable. The case of Kivu, a region in the Eastern Democratic Republic of Congo (DRC), is alarming. Decades of unresolved regional conflicts birthed armed groups that have massacred inhabitants and injured several children. This regional instability has also created barriers to seeking and obtaining timely care, decreasing the survival rate. This region's lack of data on paediatric fatal and nonfatal firearm injuries (F&NFFIs) needs studying. Thus, we aim to determine the prevalence and evaluate the outcomes of paediatric F&NFFIs in Kivu.

METHODS

We included all F&NFFI paediatric patients (≤18 years), admitted at our institution between 2017 and 2020. We extracted data from patient records. Next, we assessed the relationship between determinants of paediatric outcomes using the Chi-square test and the student's t-test. Confounders were identified using cox regression.

RESULTS

This study included 101 paediatric patients, mostly male (63.4%), with an average age of 15.9 years residing 164.4 km on average from the hospital. On average, they were admitted 2.9 days post-injury, with the most affected anatomical regions being lower limbs (53.5%) and upper limbs (18.8%). The mean length of stay was 52.9 days, and the mortality rate was 4.0%. Also, injury complications increased the mean length of stay and mortality rate. In addition, mortality was correlated with circulatory failure and anaemia.

DISCUSSION

Paediatric F&NFFIs in Eastern DRC is a preventable tragedy. Mortality is increased by injury complications and correlates with some biological factors. Prevention strategies should be developed to protect children and appropriate measures should be established to improve rates of prehospital care and early hospital presentation to lower mortality and improve paediatric outcomes.

Identifying Barriers and Facilitators to the Improvement of Healthcare Delivery and Ethics in Two Cameroonian Neurosurgical Centers

BACKGROUND

Low-and middle-income countries (LMICs) are disproportionately affected by neurosurgical burden of disease. This health inequity causes constraints in decision-making. Neurosurgical ethics helps us to assess the moral acceptability and effectiveness of clinical decisions. We aimed to assess ethical neurosurgical care and its effect on patient satisfaction in Cameroon.

METHODS

Two questionnaires hosted on Google Forms were administered among inpatients and staff at two Cameroonian neurosurgery centers. The questionnaires covered the factors influencing health outcomes and ethics. Data were collected from November 11, 2020, to March 11, 2021 and analyzed with SPSS v 26 to generate non-parametric tests with a threshold of significance at 0.05.

RESULTS

Seventy patients and twenty healthcare providers responded to the survey. Most patients faced financial hardship (57.1%; 95% CI = 45.7-68.6%), and felt that this affected the care they received (P = 0.02). Patients noticed changes in the care plan and care delivery attributable to the neurosurgical units' lack of resources. According to the patients and caregivers, these changes happened 31.0-50.0% of the time (42.9%, 95% CI = 5.7-21.4%). The majority of patients were pleased with their involvement in the decision-making process (58.6%; 95% CI = 47.1-70.0%) and felt their autonomy was respected (87.1%; 95% CI = 78.6-94.3%).

CONCLUSION

Multiple challenges to neurosurgical ethical care were seen in our study. Multimodal interventions based on the four ethical principles discussed are necessary to improve ethical neurosurgical decision-making in this low resource setting.

Management and Outcomes of Low-Grade Gliomas in Africa: A Scoping Review Protocol

Background:

Over the last decade, many advancements have been made in the management of low-grade gliomas (LGGs). Overall survival outcomes are correlated with factors such as postoperative residual volumes and specific tumor biomolecular profiles such as IDH mutation status. It is unclear whether these advancements have benefited LGG patients in Africa. This scoping review protocol outlines how the authors will evaluate the epidemiology, presentations, management and outcomes of LGGs in Africa.

Methods:

MEDLINE, Embase and African Journals Online will be searched from database inception to date in order to identify the relevant studies. Patients of all ages with histologically and/or radiologically confirmed LGGs that were managed in an African country will be included. Surgical and chemoradiation management of LGG tumours will be considered. Original research, reviews, commentaries, editorials and case reports will be included.

Results:

Primary outcomes of the review will include LGG management, morbidity and mortality. Secondary outcomes include epidemiology and recurrence of LGGs.

Discussion:

This scoping review will be the first to evaluate the current landscape of LGG management and outcomes in Africa, highlighting pertinent themes that may be used to guide further research as well as health system strengthening efforts by policymakers and stakeholders.

Scoping Review Registration:

The protocol has been registered on the Open Science Framework (OSF; registration link: https://doi.org/10.17605/OSF.IO/E732G).

Neurosurgical Equipment Donations: A Qualitative Study

Introduction

Neurosurgical equipment donation from high-income countries (HICs) to low-and-middle income countries (LMICs) exists. However, there is currently no published literature on whether there is a need for neurosurgical equipment donations or how to design equipment donation programmes that meet the needs of LMIC neurosurgeons. The primary aims of this study were to explore: (1) the need for the donation of neurosurgical equipment from the UK and Ireland to LMICs within the African continent, and (2) the ways through which neurosurgical equipment donations could meet the needs of LMIC neurosurgeons.

Methods

This was a qualitative study using semi-structured, one-on-one, audio-recorded interviews. Purposive sampling was used to recruit and interview consultants or attending neurosurgeons from Ireland, the UK and LMICs in Africa in a continuous process until data saturation. Interviews were conducted by members of the Association of Future African Neurosurgeons during March 2021. Qualitative analysis used a thematic approach using open and axial coding.

Results

Five HIC and 3 LMIC neurosurgeons were interviewed. Five overarching themes were identified: (1) inequality of access to neurosurgical equipment, (2) identifying specific neurosurgical equipment needs, (3) importance of organisations, (4) partnerships between LMIC and HIC centres, and (5) donations are insufficient in isolation.

Conclusion

There is a need for greater access to neurosurgical equipment in LMICs. It is unclear if neurosurgical equipment donations are the optimal solution to this issue. Other solutions that are not linked to dependency need to be explored and executed. Collaborative relationships between LMICs and HICs better ensures that neurosurgical equipment donations meet the needs of the recipients. These relationships may be best created within an organisation framework that has the logistical capabilities of coordinating international equipment donation and providing a quality control measure.

Should the direct aspiration first pass technique be advocated over the stent-retriever technique for acute ischemic stroke? A systematic review and meta-analysis of 7692 patients

Background:

The present meta-analysis aimed to synthesize evidence from all published studies with head-to-head data on the outcomes of a direct aspiration first pass technique (ADAPT) and the stent-retriever (SR) in acute ischemic stroke (AIS) patients.

Methods:

We searched PubMed, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials from inception to March 2021 for relevant clinical trials and observational studies. Eligible studies were identified, and all relevant outcomes were pooled in the meta-analysis random-effects model of DerSimonian-Laird.

Results:

Thirty studies were included in the meta-analysis with a total of 7868 patients. Compared with the SR, the ADAPT provides slightly higher rates of successful recanalization (RR 1.06, 95% CI [1.02 to 1.10]) and complete recanalization (RR 1.20, 95% CI [1.01 to 1.43]) but with more need for rescue therapy (RR 1.81, 95% CI [1.29 to 2.54]). There were no significant differences between the two techniques in terms of mortality at discharge, mortality at 90 days, change in the National Institutes of Health Stroke Scale score, the favorable outcome (modified Rankin scale (mRS) of 0-2), time to the groin puncture, or frequency of complications as intracerebral hemorrhage (ICH), symptomatic intracranial hemorrhage (sICH), embolus in a new territory (ENT), hemorrhagic infarction, parenchymal hematoma, subarachnoid hemorrhage, or procedural complications (all P > 0.05).

Conclusion:

Current evidence supports the use of the ADAPT technique to achieve successful and complete recanalization while considering the higher need for rescue therapy in some patients.

The Burden of Pediatric Subarachnoid Hemorrhage Healthcare Disparities in Senegal: A Retrospective Cohort Study

INTRODUCTION

Pediatric aneurysms are uncommon but potentially deadly clinical conditions with varied etiology and outcomes. In low-resource countries, numerous barriers prevent the timely diagnosis and management of pediatric aneurysmal subarachnoid hemorrhage (aSAH). Thus, this study aimed to assess the mortality of pediatric aSAH stemming from limited access to pediatric neurological surgery care in Senegal.

METHODS

Pediatric aSAH patients admitted at the authors' institution from 2012 to 2020 were recruited. Spearman Rho's correlation, McNemar's test, and Wilcoxon signed-rank test were used. Odds ratios and their 95% confidence intervals were calculated, and the population attributable fraction (PAF) was used to quantify aSAH mortality attributable to lack of surgical care.

RESULTS

Twenty-four pediatric patients (12 females and 12 males) aged 12.2 (95% CI = 10.0-14.3) years presented with aSAH. Most patients had a single aneurysm measuring 12.6 (6.1-19.0) mm with 1 patient having 2. The median WFNS grade was 3 (range [1-4]), and the mean Fisher grade was 4 (range [1-4]). Fifteen patients (62.5%) had surgical treatment on day 15.0 (IQR = 23.0) of hospitalization. The overall mortality rate was 20.8%, and the PAF of mortality for lack of surgical treatment during hospitalization was 0.08.

CONCLUSION

Eight percent of deaths among pediatric aSAH patients who do not receive surgical treatment are attributable to lack of access to surgical treatment. Health system strengthening policies should be implemented to address this health inequity.

Health systems strengthening, dissemination, and implementation science in Africa: quo vadis?

Implementing health-system strengthening policies remains a challenge in Africa. Past successes, predictable but unanticipated flaws, underutilization of health services, traditional medicine, global inequity and poor practice by local stakeholders are some of the reasons many African countries have made little progress towards attaining global health goals. As a result, Africa has the highest disease burden despite multiple efforts from the global health community. These raise the question: what has to change so that health systems strengthening efforts in Africa are successful?

Evaluating the Usefulness of YouTube as a Source of Patient Information for Neurosurgical Care in Africa: A Study Protocol

BACKGROUND

A significant proportion of the public rely on the internet for their health information, and social media has emerged as the principal information source. YouTube is the world's largest and most popular video library, and it has emerged as a primary health information source because it offers animated and interactive content. However, little is known of its usefulness of neurosurgery videos to African YouTube users. We aim with this study to evaluate the usefulness of YouTube as a source of patient information for neurosurgical care in Africa.

METHODOLOGY

This observational study will be conducted using YouTube. A search will be carried out to identify neurosurgery videos suggested to African YouTube viewers from inception to September 2021. An internet browser (Google Chrome, Google Inc., CA, USA) with its cache cleared will be used to execute the search. The default YouTube search setting of "relevance" will be used to replicate what a search attempt performed by a patient would be. The first 50 results from each keyword search will be registered in a Microsoft Excel spreadsheet (Microsoft, WA, USA). The primary outcome measure is the reliability of the videos. Data will be analyzed using SPSS version 26 (IBM, WA, USA). Odds ratios and their 95% confidence intervals will be calculated. The statistically significant level will be set at 0.05. Also, a linear regression analysis will be performed to examine the effects of independent variables on continuous dependent variables.

DISSEMINATION

The study findings will be published in an academic peer-reviewed journal, and the abstract will be presented at an international conference. English and French visual and video abstracts of the methods and key findings will be designed and disseminated widely on social media.

HIGHLIGHTS

A significant proportion of the public rely on the internet and social media for health information.YouTube has emerged as the world's largest video library, and has emerged as a primary health information source.There are few safeguards to avoid dissemination of false or biased information on the platform this could negatively influence health seeking behaviorWe aim to evaluate the usefulness of YouTube as a source of patient information for neurosurgical care in Africa.The findings of this study will help evaluate the volume and quantity of African neurosurgical video content and identify best practices.

Misconceptions About Traumatic Brain Injuries in Five Sub-Saharan African Countries

Background Traumatic Brain Injury (TBI) remains a significant problem in certain regions of the world but receives little attention despite its enormous burden. This discrepancy could consequently lead to various misconceptions among the general public. This study evaluated misconceptions about TBI in five African countries. Methods Data for this cross-sectional study were collected using the Common Misconception about Traumatic Brain Injury (CM-TBI) questionnaire, which was electronically disseminated from January 16 to February 6, 2021. Associations between the percentage of correct answers and independent variables (i.e., sociodemographic characteristics and experience with TBI) were evaluated with the ANOVA test. Additionally, answers to the question items were compared against independent variables using the Chi-Square test. A P-value <0.05 was considered statistically significant. Results A total of 817 adults, 50.2% female (n=410), aged 24.3 ± 4.3 years, and majoritarily urban dwellers (94.6%, n=773) responded to the survey. They had received tertiary education (79.2%, n=647) and were from Nigeria (77.7%, n=635). Respondents had few misconceptions (mean correct answers=71.7%, 95% CI=71.0-72.4%) and the amnesia domain had the highest level of misconception (39.3%, 95% CI=37.7-40.8%). Surveyees whose friends had TBI were more knowledgeable about TBI (mean score difference=4.1%, 95% CI=1.2-6.9, P=0.01). Additionally, surveyees whose family members had experienced TBI had a better understanding of brain damage (mean score difference=5.7%, 95% CI=2.1-9.2%, P=0.002) and recovery (mean score difference=4.3%, 95% CI=0.40-8.2%, P=0.03). Conclusion This study identified some misconceptions about TBI among young adult Africans. This at-risk population should benefit from targeted education strategies to prevent TBI and reduce TBI patients' stigmatization in Africa.

Retrospective review of Google Trends to gauge the popularity of global surgery worldwide: A cross-sectional study

Introduction

Global surgery is a growing movement worldwide, but its expansion has not been quantified. Google Search is the most popular search engine worldwide, and Google Trends analyzes its queries to determine popularity trends. We used Google Trends to analyze the regional and temporal popularity of global surgery (GS). Furthermore, we compared GS with global health (GH) to understand if the two were correlated.

Methods

This is a retrospective cross-sectional study examining Google Trends of GS and GH. We searched the terms "global surgery" and "global health" on Google Trends (Google Inc., CA, USA) from January 2004 to May 2021. We identified time trends and compared the two search terms using SPSS v26 (IBM, WA, USA) to run summary descriptive analyses and Wilcoxon rank-sum tests.

Results

The ten countries most interested in GS were India (5.0%), the United Kingdom (5.0%), Ireland (4.0%), the United States (4.0%), Australia (3.0%), Canada (3.0%), New Zealand (3.0%), Germany (2.0%), South Africa (2.0%), and Nigeria (1.0%). GS became more popular after 2015 (2.3% vs. 1.3%, P < 0.001) and was consistently less popular than GH (1.6% vs. 45.3%, P = 0.04). The difference between GS and GH interest levels increased after 2015 (45.4% vs. 42.9%, P = 0.04).

Conclusion

GS is less popular than GH, more popular in high-income countries, and has become more popular after 2015 when the Lancet Commission on Global Surgery published its seminal report. The World Health Organization passed resolution WHA 68.15. Future advocacy efforts should target low- and middle-income countries primarily.

Fatal and nonfatal firearm injuries in the eastern Democratic Republic of Congo: a hospital-based retrospective descriptive cohort study assessing correlates of adult mortality

Introduction

The Eastern Democratic Republic of Congo (DRC) has been the battleground for multiple armed conflicts, resulting in many fatal and nonfatal firearm injuries (F&NFFIs). Chronic insecurity has stressed the health system’s resources and created barriers to seeking, reaching, and receiving timely care further increasing the F&NFFI burden. Our institution is the largest trauma center in the region and receives the bulk of F&NFFI cases. We aimed to identify correlates of mortality in Congolese F&NFFI patients.

Methods

We included all F&NFFI patients admitted to our institution between 2017 and 2020. We extracted data from patient charts and admission logs. We identified mortality correlates using the two-sample t-test, Chi-square test, and multivariable regression analysis. A P-value of less than 0.05 was considered statistically significant.

Results

This study included 814 adult patients, mostly male (86%) with an average age of 34.5 years and living 154.4 km away from the hospital on average. The most affected anatomical sites were the lower limbs (48.2%) and upper limbs (23.2%). The median length of stay was 34.0 days, and the in-hospital mortality rate was 3.6%. In addition, mortality was negatively correlated with diastolic blood pressure (P = 0.01), SaO₂ (P < 0.001), and hemoglobin concentration (P = 0.002).

Conclusion

F&NFFIs cause an enormous burden in the region, and mortality is correlated with some clinical and biological variables. Thus, the study findings will inform F&NFFI referral, triage, and management in low-resource and mass casualty settings.

The Burden of Traumatic Brain Injury in Sub-Saharan Africa: A Scoping Review

BACKGROUND

Despite the growing incidence of traumatic brain injury (TBI) in Sub-Saharan Africa, there is yet to be a study to map the current burden of the disease on the continent. This scoping review aims to outline the literature on TBI.

METHODS

This scoping review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping reviews. A search string was developed to identify studies relating to TBI epidemiology, management, and outcomes. The search was applied to Medline, Embase, and Global Medicus Index.

RESULTS

In total, 107 studies were included in the final analysis. More than one half originated from South Africa. Seventy-five studies were published in 2013 or later. Studies recruited a median of 115 patients: 83.5 male and 31 female. TBI affected all age groups (range = 0-105 years) and sexes but was more common among young males aged 20-40. Road traffic accidents caused TBI in a median of 71 patients. Other major causes included assault (median = 39.5) and falls (median = 12.5). Craniectomies were the most commonly reported surgical treatment (18.7%) followed by burr holes (7.5%). Four studies (3.7%) reported delays in seeking neurotrauma care, with delays in reaching a neurotrauma facility and delays in receiving care being reported in 15 studies (14%) each. Glasgow Outcome Scale score was reported in 28 (26.1%) studies, whereas quality of life measures were reported in 2 (1%). Younger age was associated with favorable outcomes.

CONCLUSIONS

There is an increased need for TBI research, education, and training in Sub-Saharan Africa. This will aid stakeholders in optimizing patient management and outcome.
