There is a notable disparity in the number of neurosurgeons available across different geographical locations. While some regions have an abundance of neurosurgeons, others face a significant shortage. In the United States, there are fewer than 3,700 neurosurgeons serving over 5,700 hospitals. This discrepancy has led to a concentration of neurological services in large population areas, leaving many rural areas without adequate coverage. The issue is further exacerbated by an increasing trend towards neurosurgeon specialization, which lengthens training programs and contributes to the overall neurosurgeon shortage. To address this disparity, collaborative efforts are needed to develop local solutions and increase the neurosurgery workforce, particularly in regions with low socioeconomic status, which tend to have fewer neurosurgeons per capita.

There are 3,500-3,700 board-certified neurosurgeons in the US
There is a shortage of neurosurgeons in the US. While there are 5,700 hospitals in the country, there are only about 3,500-3,700 board-certified neurosurgeons. The road to becoming a neurosurgeon is a long one. As Dr. Kalia explains, "To become a neurosurgeon, you first need four years of college, followed by four years of medical school, then a 7-year residency, plus a subspecialty training for 1 to 2 years. Then you must apply to become board certified." This means that the entire process can take up to 14 years.
Neurosurgery is a relatively young discipline, dating back to the early 1900s. It focuses on the nervous system, which extends throughout the body, and neurosurgeons operate on the brain, spine, and extremities. They treat congenital anomalies, trauma, tumors, vascular anomalies, seizures, infections, and abnormalities of aging, such as stroke, functional disorders, or degenerative diseases of the spine.
The neurosurgeon workforce is facing challenges due to retirements and an increasing trend towards subspecialization. This has resulted in a shortage of general neurosurgeons, with some suggesting that a four-year residency program could help produce general neurosurgeons who can stabilize patients before referring them to tertiary care centers for more complex pathologies.
The distribution of neurosurgeons is uneven across the US, with more trained physicians in the East and a shortage of physicians in rural and low-income urban areas. California is the state with the most neurosurgeons in current practice, while the Northeast has the highest number of neurosurgeons per million people.

Neurosurgeon shortages are caused by retirements and increased specialisation
There is a shortage of neurosurgeons in the United States, and this trend is expected to continue. The shortage is attributed to two main factors: retirements and increased specialisation. Firstly, a significant portion of neurosurgeons are approaching retirement age. A 2016 report noted that almost half of practising neurosurgeons were at least 55 years old. With the aging population, more neurosurgeons are expected to retire in the coming years, further exacerbating the shortage.
Secondly, the trend towards increased specialisation in neurosurgery contributes to the shortage. Major scientific breakthroughs and advanced surgical techniques have led to neurosurgeons pursuing subspecialties such as neurotrauma, neurocritical care, stroke, and brain tumours. This subspecialisation extends the duration of residency programs by one to two years and makes it challenging to keep up with advancements across the discipline. The additional time required for subspecialisation delays the entry of fully qualified neurosurgeons into the workforce, contributing to the overall shortage.
The neurosurgeon shortage is particularly acute in rural and low-income urban areas, which often have limited access to neurological services. These areas tend to face the greatest physician shortages, as specialists are clustered in large population centres. The maldistribution of neurosurgeons across geographic regions exacerbates the impact of the overall shortage.
To address the shortage, some have proposed shortening residency programs to create a general neurosurgeon pathway. This four-year residency would produce neurosurgeons capable of handling neurotrauma and common neuro procedures. These general neurosurgeons could then stabilise patients and refer them to tertiary care centres for more complex cases. Another potential solution is to increase private funding for residency training, bypassing limits on federally supported slots and accelerating the production of qualified neurosurgeons.
The shortage of neurosurgeons is a critical issue impacting the healthcare system in the United States. With an aging population and increasing demand for neurological services, addressing this shortage through policy interventions and innovative training solutions is essential to ensure adequate patient care.

Rural areas are often without coverage, with small hospitals struggling to stay open
Neurosurgery is a highly specialised field of medicine, concerned with the nervous system and addressing issues affecting the entire system. There is a shortage of neurosurgeons across the United States, with fewer than 3,700 neurosurgeons working across over 5,700 hospitals. This shortage is particularly felt in rural areas, which often have no coverage at all. The shortage is due to a number of factors, including an ageing population, retirements, and increased specialisation in training. To address this, some suggest shortening residency programs to produce general neurosurgeons, who can then pursue subspecialty training.
Rural hospitals are struggling to stay open due to financial pressures. They are often not paid enough to cover the costs of delivering care to patients, with most losing money on patient services. This is due to inadequate payments from insurance plans, and patients' inability to pay their share of treatment costs. In addition, the higher costs of delivering care to smaller patient populations in rural areas make it difficult to sustain services. As a result, many rural hospitals have been forced to close, with over 100 closing in the past decade. This has a significant impact on the communities they serve, often resulting in the loss of emergency and outpatient services.
To address the financial challenges faced by rural hospitals, some suggest that these hospitals should be transparent about their costs, efficiency, and quality of care. By doing so, they can build trust with purchasers and patients, who will be confident that payments will be used to deliver high-quality, low-cost services. Additionally, rural hospitals should focus on proactive, preventive care and chronic disease management, rather than office visits, to provide better care and reduce costs.
The closure of rural hospitals has a significant impact on the surrounding communities. Rural areas often rely on these hospitals for emergency services, particularly in the case of accidents or medical emergencies. Additionally, many rural communities depend on agriculture and energy production, which require a healthy workforce. Without adequate healthcare services, people may be less likely to live or work in these areas, impacting the local economy. Therefore, it is crucial to address the financial challenges faced by rural hospitals to ensure they can continue to provide essential healthcare services to their communities.

Neurosurgeon-to-population ratios vary across US regions
The United States faces a neurosurgeon shortage, with fewer than 3,700 neurosurgeons working across over 5,700 hospitals. This uneven distribution of neurosurgeons across the country means that some regions have a significantly greater neurosurgeon-to-population ratio than others.
The clustering of neurological services in large population areas leaves many rural and low-income urban areas without adequate coverage. States in the Midwest and South, which have some of the country's largest aging populations, face significant neurosurgeon shortages. These regions attempt to attract physicians with higher salaries and bonuses. However, the specialization of neurosurgeons and the lengthy residency programs contribute to the overall shortage.
To address this issue, some have proposed shortening residency programs to create general neurosurgeons who can stabilize patients before referring them to subspecialists. Private funding has also played a role in addressing the shortage, with individuals and organizations providing endowed funds to train neurosurgery residents. These efforts aim to improve access to neurosurgical care, particularly in underserved areas, and ensure that patients across the country have timely and equitable access to the critical services provided by neurosurgeons.

Global neurosurgeon density varies, with 29 countries, 14 territories, and 1 independent state with no neurosurgeons
Neurosurgeons are medical specialists who deal with the prevention, diagnosis, and surgical treatment of patients with injuries or disorders affecting any part of the nervous system. They address issues related to the entire nervous system, from the brain to the spinal cord and spinal column, as well as extremities where nerves are impacted, such as in carpal tunnel syndrome.
While the field of neurosurgery is crucial, there are stark disparities in the availability of neurosurgeons worldwide. According to a study by Harvard Medical School, there are approximately 72,967 neurosurgeons globally, resulting in a pooled density of 0.93 neurosurgeons per 100,000 individuals. However, this varies significantly across regions and income levels. North America has the highest density of neurosurgeons, with 1.82 per 100,000 people, while the African region has the lowest, with only 0.11 per 100,000.
The availability of neurosurgeons also differs within countries. For example, in the United States, there are around 3,500 to fewer than 3,700 board-certified neurosurgeons serving over 5,700 hospitals. Neurological services tend to cluster in large population areas, leaving many rural regions without coverage. Similarly, within the African region, some countries have no neurosurgeons at all, and those that do have limited resources for subspecialized care.
The disparities in neurosurgeon density have significant implications for access to healthcare. The study by Harvard Medical School investigators highlights that a ratio of 1 neurosurgeon per 65,000 individuals may not be sufficient to meet global needs. This is further exacerbated by the trend towards neurosurgeon specialization, which can lead to longer residency periods and potential shortages in certain regions.
To address these challenges, various solutions have been proposed, including shortening residency programs to produce general neurosurgeons who can stabilize patients before referring them to subspecialists. Additionally, private funding initiatives, such as the endowment fund established by John Sonnentag, can play a crucial role in training more neurosurgeons and bypassing limits on federally-supported residency slots.
