Developing evidence-based ethical policies on the migration of health workers: conceptual and practical challenges

Nurses on the move: a global overview

OBJECTIVE

To look at nurse migration flows in the light of national nursing workforce imbalances, examine factors that encourage or inhibit nurse mobility, and explore the potential benefits of circular migration.

PRINCIPAL FINDINGS

The number of international migrants has doubled since 1970 and nurses are increasingly part of the migratory stream. Critical nursing shortages in industrialized countries are generating a demand that is fueling energetic international recruitment campaigns. Structural adjustments in the developing countries have created severe workforce imbalances and shortfalls often coexist with large numbers of unemployed health professionals. A nurse's motivation to migrate is multifactorial, not limited to financial incentives, and barriers exist that discourage or slow the migration process. The migration flows vary in direction and magnitude over time, responding to socioeconomic factors present in source and destination countries. The dearth of data on which to develop international health human resource policy remains. There is growing recognition, however, that migration will continue and that temporary migration will be a focus of attention in the years to come.

CONCLUSIONS

Today's search for labor is a highly organized global hunt for talent that includes nurses. International migration is a symptom of the larger systemic problems that make nurses leave their jobs. Nurse mobility becomes a major issue only in a context of migrant exploitation or nursing shortage. Injecting migrant nurses into dysfunctional health systems-ones that are not capable of attracting and retaining staff domestically-will not solve the nursing shortage.

Sub-Saharan Africa: beyond the health worker migration crisis?

Migration of skilled health workers from sub-Saharan African countries has significantly increased in this century, with most countries becoming sources of migrants. Despite the growing problem of health worker migration for the effective functioning of health care systems there is a remarkable paucity and incompleteness of data. Hence, it is difficult to determine the real extent of migration from, and within, Africa, and thus develop effective forecasting or remedial policies. This global overview and the most comprehensive data indicate that the key destinations remain the USA and the UK, and that major sources are South Africa and Nigeria, but in both contexts there is now greater diversity. Migrants move primarily for economic reasons, and increasingly choose health careers because they offer migration prospects. Migration has been at considerable economic cost, it has depleted workforces, diminished the effectiveness of health care delivery and reduced the morale of the remaining workforce. Countries have sought to implement national policies to manage migration, mitigate its harmful impacts and strengthen African health care systems. Recipient countries have been reluctant to establish effective ethical codes of recruitment practice, or other forms of compensation or technology transfer, hence migration is likely to increase further in the future, diminishing the possibility of achieving the United Nations millennium development goals and exacerbating existing inequalities in access to adequate health care.

Health systems and access to antiretroviral drugs for HIV in Southern Africa: service delivery and human resources challenges

Without strengthened health systems, significant access to antiretroviral (ARV) therapy in many developing countries is unlikely to be achieved. This paper reflects on systemic challenges to scaling up ARV access in countries with both massive epidemics and weak health systems. It draws on the authors' experience in southern Africa and the World Health Organization's framework on health system performance. Whilst acknowledging the still significant gap in financing, the paper focuses on the challenges of reorienting service delivery towards chronic disease care and the human resource crisis in health systems. Inadequate supply, poor distribution, low remuneration and accelerated migration of skilled health workers are increasingly regarded as key systems constraints to scaling up of HIV treatment. Problems, however, go beyond the issue of numbers to include productivity and cultures of service delivery. As more countries receive funds for antiretroviral access programmes, strong national stewardship of these programmes becomes increasingly necessary. The paper proposes a set of short- and long-term stewardship tasks, which include resisting the verticalisation of HIV treatment, the evaluation of community health workers and their potential role in HIV treatment access, international action on the brain drain, and greater investment in national human resource functions of planning, production, remuneration and management.

Nurse migration from Zimbabwe: analysis of recent trends and impacts

The migration of nursing professionals from developing countries such as Zimbabwe to industrialised countries is taking place at an alarming rate, with little signs of slowing down. In Africa, nurses form the backbone of the healthcare delivery system and their migration has a huge negative impact on health service provision. Drawing on evidence from selected health institutions, the paper shows the magnitude of migration of nurses from Zimbabwe. The paper also shows that public to private health sector migration of nurses is occurring at a significant rate. The effects of such movements are examined in detail. For instance, at the health institution level, nurse migration has led to staff shortages, and health institutions located in the disadvantaged areas have been the worst affected. The paper calls for the adoption of an integrated approach in managing and addressing the concerns of the nursing professionals.

Nurse Staffing and Patient Outcomes in Veterans Affairs Hospitals

OBJECTIVE

To assess characteristics and perceptions of nurses working in the Veterans Health Administration (VHA), comparing types of nursing personnel, to benchmark to prior studies across healthcare systems.

BACKGROUND

Prior studies have shown relationships between positive registered nurse (RN) perceptions of the practice environment and patient outcomes. To date, no study has reported the comparison of RN perceptions of the practice environment in hospital nursing with those of non-RN nursing personnel. This study is the first to offer a more comprehensive look at perceptions of practice environment from the full range of the nursing work force and may shed light on issues such as the relationship of skill mix to nurse and patient outcomes.

METHODS

Cross-sectional observational study with a mailed survey administered to all nursing personnel in 125 VA Medical Centers between February and June 2003.

RESULTS

Compared with other types of nursing personnel in the VHA, RNs are generally less positive about their practice environments. However, compared with RNs in other countries and particularly with other RNs in the United States (Pennsylvania), VHA RNs are generally more positive about their practice environment and express more job satisfaction.

CONCLUSIONS

The nursing work force of the VHA has some unique characteristics. The practice environment for nurses in the VHA is relatively positive, and may indicate that the VHA, as a system, provides an environment that is more like magnet hospitals. This is significant for a public sector hospital system.

The flight of physicians from West Africa: views of African physicians and implications for policy

West African-trained physicians have been migrating from the sub-continent to rich countries, primarily the US and the UK, since medical education began in Nigeria and Ghana in the 1960s. In 2003, we visited six medical schools in West Africa to investigate the magnitude, causes and consequences of the migration. We conducted interviews and focus groups with faculty, administrators (deans and provosts), students and post-graduate residents in six medical schools in Ghana and Nigeria. In addition to the migration push and pull factors documented in previous literature, we learned that there is now a well-developed culture of medical migration. This culture is firmly rooted, and does not simply fail to discourage medical migration but actually encourages it. Medical school faculty are role models for the benefits of migration (and subsequent return), and they are proud of their students who successfully emigrate.

Nurses' working conditions: implications for infectious disease

Staffing patterns and nurses' working conditions are risk factors for healthcare-associated infections as well as occupational injuries and infections. Staffing shortages, especially of nurses, have been identified as one of the major factors expected to constrain hospitals' ability to deal with future outbreaks of emerging infections. These problems are compounded by a global nursing shortage. Understanding and improving nurses' working conditions can potentially decrease the incidence of many infectious diseases. Relevant research is reviewed, and policy options are discussed.

The health workforce: managing the crisis ethical international recruitment of health professionals: will codes of practice protect developing country health systems?

Many countries are using the strategy of international recruitment to make up for shortages of health professionals to the detriment of health systems in the poorest parts of the world. This study reviewed the potential impact of eight national level and international codes of practice or similar instruments that are being introduced to encourage ethical recruitment in order to protect these countries. Whilst effective dissemination of the instruments is generally in place, support systems, incentives and sanctions and monitoring systems necessary for effective implementation and sustainability are currently weak or have not been planned. If such codes or instruments are to be used to protect developing country health systems, lessons should be learnt from the early adopters; the focus of protecting developing country health systems needs to be emphasised in instruments with multiple objectives; the process of implementing the instruments strengthened; and internal and external pressure needs to be increased to ensure the codes and instruments lead to ethical recruitment and help to protect developing country health systems.

Physician migration: views from professionals in Colombia, Nigeria, India, Pakistan and the Philippines

There has been much debate recently about several issues related to the migration of physicians from developing to developed countries. However, few studies have been conducted to address these issues in a systematic fashion. In an attempt to begin the process of generating systematic data, we designed and distributed a questionnaire addressing several core issues surrounding physician migration to respondents selected on the basis of their special expertise or experience in India, Nigeria, Pakistan, Colombia, and the Philippines. The issues addressed relate to the reasons physicians migrate to developed countries, how migration is related to the structure of medical education, the effect that migration has on the health care infrastructure of developing countries, and various policy options for dealing with physician migration. Though responses varied somewhat by country, a desire for increased income, greater access to enhanced technology, an atmosphere of general security and stability, and improved prospects for one's children were the primary motivating factors for physician migration. A majority of respondents believed that physicians in developing counties are provided with highly specialized skills that they can better utilize in developed countries, but respondents were ambivalent with respect to the utility of educational reform. Responses varied significantly by country with regard to whether physician migration results in physician shortages, but there was widespread agreement that it exacerbates shortages in rural and public settings. With respect to policy options, increasing physician income, improving working conditions, requiring physicians to work in their home countries for a period following graduation from medical school, and creating increased collaboration between health ministries in developed and developing countries found the most favor with respondents.

The migration of physicians from sub-Saharan Africa to the United States of America: measures of the African brain drain

BACKGROUND: The objective of this paper is to describe the numbers, characteristics, and trends in the migration to the United States of physicians trained in sub-Saharan Africa. METHODS: We used the American Medical Association 2002 Masterfile to identify and describe physicians who received their medical training in sub-Saharan Africa and are currently practicing in the USA. RESULTS: More than 23% of America's 771 491 physicians received their medical training outside the USA, the majority (64%) in low-income or lower middle-income countries. A total of 5334 physicians from sub-Saharan Africa are in that group, a number that represents more than 6% of the physicians practicing in sub-Saharan Africa now. Nearly 86% of these Africans practicing in the USA originate from only three countries: Nigeria, South Africa and Ghana. Furthermore, 79% were trained at only 10 medical schools. CONCLUSIONS: Physician migration from poor countries to rich ones contributes to worldwide health workforce imbalances that may be detrimental to the health systems of source countries. The migration of over 5000 doctors from sub-Saharan Africa to the USA has had a significantly negative effect on the doctor-to-population ratio of Africa. The finding that the bulk of migration occurs from only a few countries and medical schools suggests policy interventions in only a few locations could be effective in stemming the brain drain.

Recruitment of consultant psychiatrists from low- and middle-income countries

The UK's 2-year International Fellowship Programme for consultant doctors has inadvertently highlighted the long-standing issues of the costs and benefits of such recruitment for the countries of origin, and of whether it is ethical for rich countries to recruit health personnel not only from other rich countries but also from low- and middle-income countries. The 'brain drain' from poor to rich countries has been recognised for decades; it occurs in the health sector as well as other sectors, such as education, science and engineering. It has had serious ramifications for the health service infrastructure in low-income countries, where poverty, morbidity, disability and mortality are increasing rather than decreasing, and it is a matter of serious concern for both the World Health Organization and the International Monetary Fund (Carrington & Detragiache, 1998; Lee, 2003).

Impact, regulation and health policy implications of physician migration in OECD countries

BACKGROUND: In the face of rising demand for medical services due to ageing populations, physician migration flows are increasingly affecting the supply of physicians in Organisation for Economic Co-operation and development (OECD) countries. This paper offers an integrated perspective on the impact of physician migration on home and host countries and discusses international regulation and policy approaches governing physician migration. METHODS: Information about migration flows, international regulation and policies governing physician migration were derived from two questionnaires sent to OECD countries, a secondary analysis of EUROSTAT Labour Force Surveys, a literature review and official policy documents of OECD countries. RESULTS: OECD countries increasingly perceive immigration of foreign physicians as a way of sustaining their physician workforce. As a result, countries have entered into international agreements regulating physician migration, although their success has been limited due to the imposition of licensing requirements and the protection of vested interests by domestic physicians. OECD countries have therefore adopted specific policies designed to stimulate the immigration of foreign physicians, whilst minimising its negative impact on the home country. Measures promoting immigration have included international recruitment campaigns, less strict immigration requirements and arrangements that foster shared learning between health care systems. Policies restricting the societal costs of physician emigration from developing countries such as good practice guidelines and taxes on host countries have not yet produced their expected effect or in some cases have not been established at all. CONCLUSIONS: Although OECD countries generally favour long-term policies of national self-sufficiency to sustain their physician workforce, such policies usually co-exist with short-term or medium-term policies to attract foreign physicians. As this is likely to continue, there is a need to create a global framework that enforces physician migration policies that confer benefits on home and host countries. In the long term, OECD countries need to put in place appropriate education and training policies rather than rely on physician migration to address their future needs.

Trends In International Nurse Migration

Predicted shortages and recruitment targets for nurses in developed countries threaten to deplete nurse supply and undermine global health initiatives in developing countries. A twofold approach is required, involving greater diligence by developing countries in creating a largely sustainable domestic nurse workforce and their greater investment through international aid in building nursing education capacity in the less developed countries that supply them with nurses.

"Brain drain" or ethical recruitment?

Recruitment by wealthy countries of health personnel from developing countries is threatening the viability of crucial health programs in poor countries, especially in sub-Saharan Africa. Australia has participated in this "brain drain", although the extent and impact of this on different countries has not been adequately assessed. Australia depends on overseas-trained doctors to fill vacancies in public hospitals and private practice, particularly in rural and outer suburban areas where locally trained professionals are reluctant to work. Australia should adopt national strategies to minimise harm and maximise benefits of skills migration; concerted international action will also be required.
