“Brain drain” of health professionals: from rhetoric to responsible action
Introduction
There are an estimated 35 million people working in the health sector worldwide [1]. This essential global resource is not equitably shared between countries, largely due to the extent of international migration of health professionals.
‘Brain drain’, as professional migration is sometimes called, in the health sector is not a new phenomenon. Concerns over the international movement of health workers were expressed at Edinburgh Commonwealth Medical Conference in 1965. In the 1970s the World Health Organisation was prompted to examine the global stocks and flows of doctors and nurses in what is the only study of its kind [2]. This report made little impact and migration of health professionals has gradually increased over the years [3], [4], [5]. As the large scale movement of health professionals from developing countries is now impacting on the health systems of those countries it is imperative to develop a meaningful dialogue among stakeholders in the search for urgently needed solutions.
This paper focuses on the responsibilities of importing or ‘recipient’ countries and exporting or ‘source’ countries as well as responsibilities at a global level. The implications for appropriate policies are addressed. The paper draws on an exploratory study carried out in three countries: Ghana (a net exporter); South Africa (an importer and exporter); and England (a net importer). The aim of the research was to find out what was known about the extent of migration and its impact and the kind of policies being used to influence flows by source and recipient countries. Key informants were selected purposively and interviewed during 1-week trips to Ghana and South Africa in late 2000 and interviews in the UK took place over a longer period in 2001 to early 2002. The informants were drawn from government, academia, senior health service managers, professional councils, students, development organisations and one recruitment agency. The semi-structured questionnaire covered the following areas: the extent of migration; the process and reasons for migration; the impact on source country health systems; and policies and strategies being used to influence migration. The findings from this study have been supplemented by a review of the literature and monitoring of relevant contemporary events.

Contemporary migration
Migration is possible for all health professionals who have marketable skills. Traditionally doctors and nurses have made up the bulk of migrants. More recently there has been increased movement of other health professionals such as pharmacists, physiotherapists and other professional groups involved with health care.
In the 1960s and 1970s past colonial cultural ties (including language) were very important in determining migratory patterns. For example, there was a high proportion of British
Negative impacts
‘Receiving’ countries benefit from international migration. From a national perspective savings are made in training and education costs from this form of ‘free riding’. Employers may also benefit from migrants’ flexibility of working, being more prepared to work in less desirable areas of work (for example, mental health), under less socially acceptable conditions (e.g. night shifts) and less desirable geographic regions (e.g. the rural areas of South Africa or Canada, or the inner cities of
Future prospects
There are many signs that the pull from richer countries will increase over the next 10–20 years [22]; it is estimated that a further one million nurses will be needed over the next 10 years to meet the shortfall in the US [23]. In addition to the general expansion of health care provision based on previous trends, these countries will have to cater for an increasingly ageing population. For example, in the UK it is estimated that the population aged 80 and over group will grow from 2.4 million
Policy issues
Policy makers need to work on the assumption that the international migration of health professionals will continue. There are therefore a number of key policy issues [15], [30] around protecting the interests of the health services in the poorest countries. These policy issues are considerably more pertinent given the risks to the proposed new investments in health care systems in sub-Saharan Africa [31] posed by staff shortages. These policy issues can be organised in terms of levels of
Conclusion
The negative impact on health services in certain poor countries of mass recruitment of health professionals by industrialised countries seems to be beyond dispute. Since the pressure from richer nations on the international health labour market is clearly set to increase the situation is likely to get worse.
The problem is not helped by oversimplifying the debate to one of heartless employers in the North poaching from the helpless South. A recognition of the complexity of stakeholder

Is there a ‘pig cycle’ in the labour supply of doctors? How training and immigration policies respond to physician shortages
2018, Social Science and MedicineCitation Excerpt :Currently, on average, foreign-trained physicians represent 17.1 per cent of the physician workforce in OECD countries (OECD, 2016). The need to recruit physicians from abroad is mainly explained by: (1) the lack of support for the cost of training of a doctor (Martineau et al., 2004), (2) the inability of the educational system to ensure an equal distribution of health care workers within the country (Ono et al., 2014), and (3) the rigidity of the adjustments to medical school capacity and the time it takes to respond to a shortage (OECD, 2008). Indeed, in all OECD countries, the number of seats offered by medical schools each year is fixed (OECD, 2008).
