Long term postoperative results and quality of life after surgery for lumbar spinal stenosis in sub-sahara African countries, the case of Cameroon: A cross-sectional study.

Objectives: Lumbar spinal stenosis is a frequent and disabling disease of the elderly. However, the impact of its surgery on the long term (≥5 years) postoperative results and quality of life has not yet been evaluated in our setting. Methods: The study population consisted of 224 patients operated between 2010 and 2017 at the Yaounde Central Hospital and the Yaounde General Hospital, of whom 33 were evaluated. Long term postoperative results were defined as reoperations, indication for reoperation, time elapsed to reoperation and control-X ray findings. Quality of life (QOL) was evaluated using the Oswestry Disability Index (ODI) and Numerical Pain Rating Scale (NRS), and compared to reported preoperative values. The one-way analysis of variance and Kruskal-Wallis tests were used for associations between patient characteristics and quality of life outcomes. Results: Participants had a mean age of 57.3 years. 21% of participants were reoperated at least once, two years later on average due to reappearance of their clinical pictures. QOL significantly improved from being crippled (mean ODI 67.5%) and having severe pain (mean NRS 8) before surgery, to moderate disability (mean ODI 34.4%, p < 0.01) and moderate pain (means NRS 4, p < 0.01) five years later. Having large family support was the only factor independently associated with improved ODI and NRS (p = 0.01). Conclusion: Lumbar spinal stenosis surgery is still beneficial five years later. Large cohort studies need to be conducted in our setting.

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.

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.

State of Neurosurgical Education in Africa: A Narrative Review.

BACKGROUND: There is no comprehensive report of neurosurgery postgraduate education in Africa. This narrative review aimed to map out the landscape of neurosurgery training in Africa and highlight similarities and differences in training. METHODS: The keywords "neurosurgery," "education," and "Africa" were searched on PubMed and Google Scholar from inception to January 17, 2021. Next, a complementary hand search was conducted on Google using the keywords "neurosurgery," "residency," and the individual African countries in English and official languages. The relevant data were extracted and compiled into a narrative review. RESULTS: A total of 76 African training programs that recruit more than 168 trainees each year were identified. Less than half (40.7%, n = 22) of African countries have at least 1 neurosurgery training program. Egypt (n = 15), Algeria (n = 14), and Nigeria (n = 10) have the highest number of training programs, whereas Algeria (0.33), Egypt (0.15), and Libya (0.15) have the highest number of training programs per 1 million inhabitants. The College of Surgeons of East, Central, and Southern Africa has 16 programs in 8 countries, whereas the West African College of Surgeons has 17 accredited programs in 3 countries. The duration of training varies between 4 and 8 years. There is limited information available in the public domain and academic literature about subspecialty fellowships in Africa. CONCLUSIONS: This review provides prospective applicants and African and global neurosurgery stakeholders with information to advocate for increased investment in African neurosurgery training programs.

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.
