A Geospatial Analysis of the Availability, Distribution, and Accessibility of Neurosurgical Facilities, Workforce, and Infrastructure in Nigeria; and Projection Towards 2050.

OBJECTIVE: There has been a modest but progressive increase in the neurosurgical workforce, training, and service delivery in Nigeria in the last 2 decades. However, these resources are unevenly distributed. This study aimed to quantitatively assess the availability and distribution of neurosurgical resources in Nigeria while projecting the needed workforce capacity up to 2050. METHODS: An online survey of Nigerian neurosurgeons and residents assessed the country's neurosurgical infrastructure, workforce, and resources. The results were analyzed descriptively, and geospatial analysis was used to map their distribution. A projection model was fitted to predict workforce targets for 2022-2050. RESULTS: Out of 86 neurosurgery-capable health facilities, 65.1% were public hospitals, with only 17.4% accredited for residency training. Dedicated hospital beds and operating rooms for neurosurgery make up only 4.0% and 15.4% of the total, respectively. The population disease burden is estimated at 50.2 per 100,000, while the operative coverage was 153.2 cases per neurosurgeon. There are currently 132 neurosurgeons and 114 neurosurgery residents for a population of 218 million (ratio 1:1.65 million). There is an annual growth rate of 8.3%, resulting in a projected deficit of 1113 neurosurgeons by 2030 and 1104 by 2050. Timely access to neurosurgical care ranges from 21.6% to 86.7% of the population within different timeframes. CONCLUSIONS: Collaborative interventions are needed to address gaps in Nigeria's neurosurgical capacity. Investments in training, infrastructure, and funding are necessary for sustainable development and optimized outcomes.

Improving capacity and access to neurosurgery in sub-Saharan Africa using a twinning paradigm pioneered by the Swedish African Neurosurgical Collaboration.

BACKGROUND: The unmet need for neurosurgery in sub-Saharan Africa is staggering. Resolving this requires strategies that synergize salient local resources with tailored foreign help. This study is a trial of a twinning model adopted by the Swedish African Neurosurgical Collaboration (SANC). METHODS: A multi-step neurosurgical twinning technique, International Neurosurgical Twinning Modeled for Africa (INTIMA), developed through a collaboration between African and Swedish neurosurgical teams was adopted for a neurosurgical mission in March 2019. The pioneering steps are evaluated together with data of treated patients prospectively acquired using SPSS Chicago Inc., Version 23. Associations were analyzed using chi-square tests, while inferences were evaluated at 95% level of significance. RESULTS: The SANC global neurosurgery mission targeted microsurgical brain tumor resection. Fifty-five patients were operated on during the mission and subsequent 3 months. Patients' ages ranged from 3 months to 69 years with a mean of 30.6 ± 2.1 years 95% CL. Seven cases were performed during the first mission, while 48 were performed after the mission. Compared to 3 months before SANC when only 9 brain tumors were resected, more tumors were resected (n = 25) within the 3 consecutive months from the mission (X2 = 14.2, DF = 1, P = 0.000). Thirty-day mortality following tumor resection was also lower, X2 = 4.8, DF = 1, P = 0.028. CONCLUSION: Improvements in capacity and short-term outcome define our initial pioneering application of a neurosurgical twinning paradigm pioneered by SANC.

The Ebb and Flow of Neurosurgery in a Re-Emerging Sub-Saharan Center. Lessons from 1025 Consecutive Operated Cases and Progress Models. A Prospective Observational Cohort Study.

BACKGROUND: The evolution of neurosurgery in our center comprises 2 active phases separated by a decade-long latent phase. This study evaluates our experience in the renaissance phase using 1025 cases. We identify paradigms that predict progress under existing practice conditions. METHODS: A prospective observational study was undertaken of all freshly operated patients from 2009 to 2016. Ethical approval was obtained from the hospital institutional review board. Data of enrolled patients were acquired and analyzed using SPSS software for Windows version 21. Inferences were evaluated using a 95% level of significance. Major and intermediate cases were included, whereas bedside cases as well as patients operated on elsewhere were excluded. RESULTS: Of 5132 patients treated, 3033 had surgical lesions, 1129 (33.2 ± 2.7% confidence limit [CL]) were operated on, and 1025 satisfied the study criteria. The unmet surgical load (66.1%) was significant (χ2 = 10.9; degree of freedom = 1; P = 0.001). The most common diseases treated were neurotrauma in 438 patients, congenital malformations in 268, and tumors in 170. The mean annual operative rate was 125 ± 5.7 patients (95% CL). Cases showed significant variability using 1-way analysis of variance (F = 13.77; P = 0.03). Residency training was a positive influence on surgeons' operative rate (χ2 = 7.59; P = 0.02). The mean complication rate was 10.3% ± 2.9%, and the mortality was 5.5% ± 1.7%. CONCLUSIONS: We found a large unmet neurosurgical load. To resolve this situation, we recommend an increase in the number of training programs for neurosurgery residency. As neurosurgery units evolve, their progress may be evaluated using the NESCAPE (Neurosurgery Care Phase Evolution) paradigm.
