Abstract：
Every year, there are an estimated 22.6 million new neurosurgical consultative cases worldwide, of which 13.8 million require surgery. In 2016, the global neurosurgical workforce was estimated and mapped as open-access information to guide neurosurgeons, affiliates, and policy makers. We present a subsequent investigation for mapping the global neurosurgical workforce for 2018 to show the replicability of previous data collection methods as well as to show any changes in workforce density.
We extracted data on the absolute number of neurosurgeons per low and middle-income countries (LMICs) in 2016 from the database of the global neurosurgical workforce mapping project. The estimated number of neurosurgeons in each LMIC during 2018 was obtained from collaborators. The median workforce densities were calculated for 2016 and 2018. Neurosurgical workforce density heat maps were generated.
We received data from 119 countries (response rate 86.2%) and imputed data for 19 countries (13.8%). Seventy-eight (56.5%, N = 138) countries had an increase in their number of neurosurgeons, 9 (6.5%) showed a decrease, whereas 51 (37.0%) had the same number of neurosurgeons in both years. The pooled median increased from 0.17 (interquartile range, 0.54) in 2016 to 0.18 (interquartile range, 0.59) in 2018.
Overall, the density of the neurosurgical workforce has increased from 2016 to 2018. However, at the current rate, 80 LMICs (58.0%) will not meet the neurosurgical workforce density target by 2030.

摘要：
每年,全球估计有2260万新的神经外科咨询病例，其中1380万人需要手术。2016年，对全球神经外科劳动力进行了评估，并将其映射为开放获取的信息，以指导神经外科医生。附属公司，和政策制定者。我们提出了一项针对2018年全球神经外科劳动力的后续调查，以显示以前的数据收集方法的可复制性，并显示劳动力密度的任何变化。
我们从全球神经外科劳动力映射项目数据库中提取了2016年每个低收入和中等收入国家（LMICs）神经外科医生绝对人数的数据。2018年每个LMIC的神经外科医生的估计人数来自合作者。计算了2016年和2018年的劳动力密度中位数。生成了神经外科劳动力密度热图。
我们收到了119个国家的数据（回应率86.2%）和19个国家的数据（13.8%）。七十八（56.5%，N=138）国家的神经外科医生人数有所增加，9(6.5%)显示下降，而51名(37.0%)的神经外科医生在两年中的数量相同.合并中位数从0.17增加(四分位数间距，0.54)2016年至0.18(四分位数间距，0.59）2018年。
总的来说，神经外科劳动力的密度从2016年到2018年有所增加。然而,以目前的速度，到2030年，80个LMIC（58.0％）将无法达到神经外科劳动力密度目标。
