Africa: Brain Drain Is a Hidden Tax On the Countries Left Behind

Dr John Baptist Mukasa, or JB Neuro, as his colleagues called him, “was always at the beck and call of everyone who needed neurosurgical care”, according to his colleague Dr Sabrina Kitaka. Mukasa’s death from COVID on June 29, in the middle of Uganda’s most lethal wave so far, robbed the country’s medical fellowship of a friend and a mentor.

It also cut the total number of neurosurgeons in Uganda by 25%.

Only three neurosurgeons remain in Uganda, a country of 44 million people (although some estimates put the workforce as high as ten). By comparison, Canada, with a population of 35 million, has over 150 neurosurgeons. New York City’s Columbia Presbyterian Hospital, where I did my residency, has 17 neurosurgeons in one department alone – several times larger than the entire neurosurgical workforce of Uganda.

There are many reasons for this disparity, including a lack of training facilities and hospitals capable of supporting complex surgical care. And then there’s the brain drain – the migration of trained professionals out of a country to other, often wealthier, locations.

Brain drain is taxation

There are many reasons doctors leave. A higher salary, access to education, stable political conditions, improved standards of living, increased perceived quality of life, and greater personal safety all draw doctors away from their homes and often to countries that previously colonised theirs.

It’s a multi-billion-dollar industry. Recently, my colleagues and I published an estimate of the economic effect of the migration of doctors (we didn’t have enough information to look at the migration of nurses or other health professionals). We found that countries lose somewhere between US$3.5 billion and US$38 billion a year as a result of the excess deaths that brain drain causes. The countries exporting the greatest number of doctors incur the largest costs: India, Nigeria, Pakistan and South Africa.

In other words, not only do the countries to which doctors migrate benefit from an influx of trained, experienced professionals, they also inflict what is essentially a tax on the economies of source countries — all for the privilege of attracting away their clinical staff.

Brain drain and COVID

In 2010, the World Health Organization agreed the Global Code of Practice on the International Recruitment of Health Personnel. This agreement encouraged source countries to hold onto their healthcare workforce by improving education, living standards and working conditions (it didn’t address how this could be achieved in the face of limited resources). The agreement also required destination countries to stop recruiting from countries with a shortage of healthcare workers.

But that never happened. In fact, at the beginning of the COVID pandemic, active recruitment of doctors from these source countries stepped up as the scale of the crisis became clear.
