The UK is home to over 4,700 doctors who trained in Nigeria, providing a substantial subsidy from the African country to the UK, says this multi-signatory letter from experts, and Parry Mitchell suggests ways to tempt back medics who have moved abroad

The scrapping of the immigration cap is a rare victory for freedom of movement (Immigration cap on doctors to be lifted, 15 June), but the global health inequalities underlying the issue need to be part of the debate. The shortage of health workers is a global problem, particularly acute in parts of Africa and Asia, fuelled by global health inequalities. Nigeria has one doctor for every 2,660 people, compared to one doctor for every 354 in the UK. The UK is home to over 4,700 doctors who trained in Nigeria, providing a substantial subsidy from Nigeria to the UK.

In order to meet its commitment to increase NHS England funding by £8bn, the government cut “non-NHS England” funding (which includes funding for training health workers) by £4bn – a cut of 24% in real terms. If it intends to rely on some of the world’s poorest countries to fill the gap, it must put in place a mechanism to adequately compensate them.

• Is there a quick and cheap way to recruit high-quality doctors and nurses who are familiar with our NHS system and who are exceptionally well trained? Yes, there is.

Many thousands of UK-qualified medics have moved abroad – to the US, Australia, New Zealand and Canada. But situations change, some get homesick, some see opportunities in the UK, and some are even concerned about elderly family members. Whatever their reasons, they are ripe for the picking. But the NHS often makes coming home unnecessarily difficult, penalising the doctors for having gone abroad, sometimes even making them feel guilty.

So why doesn’t the NHS work with our embassies, high commissions and consulates to establish contact with the overseas NHS alumni? Tell them what’s on offer and make it easy for them to come home. Make them feel welcome and value their training abroad. After all, they speak English, understand the system and, best of all, they won’t need a visa.
