Health workforce imbalances in times of globalization: brain drain or professional mobility?

The health workforce is of strategic importance to the performance of national health systems as well as of international disease control initiatives. The brain drain from rural to urban areas, and from developing to industrialized countries is a long-standing phenomenon in the health professions but has in recent years taken extreme proportions, particularly in Africa. Adopting the wider perspective of health workforce balances, this paper presents an analysis of the underlying mechanisms of health professional migration and possible strategies to reduce its negative impact on health services. The opening up of international borders for goods and labour, a key strategy in the current liberal global economy, is accompanied by a linguistic shift from 'human capital flight' and 'brain drain' to 'professional mobility' or 'brain circulation'. In reality, this mobility is very asymmetrical, to the detriment of less developed countries, which lose not only much-needed human resources, but also considerable investments in education and fiscal income. It is argued that low professional satisfaction and the decreasing social valuation of the health professionals are important determinants of the decreasing attraction of the health professions, which underlies both the push from the exporting countries, as well as the pull from the recipient countries. Solutions should therefore be based on this wider perspective, interrelating health workforce imbalances between, but also within developing and developed countries.

The Australian health workforce: facts and futures.

The quality of care received by a patient or consumer critically depends on the knowledge, skills and attitudes of the health workforce; the structure and functioning of the health workforce is critical to the structure and functioning of the health system overall. To a very large extent, diagnosis and treatment decisions call on the training and experience of the health professional. The quality of the interaction between a patient or consumer depends on the interpersonal and technical skills of health professionals. In a sense, health workers are important to defining the very nature of health care services. The importance of the health workforce is further highlighted by the fact that, as is typical of most service industries, labour accounts for a large proportion of health costs (around 80%). This paper provides an overview of the size and composition of the health workforce in Australia. It then reviews three segments of the workforce in more detail (medical, nursing and other health professionals) and reviews contemporary policy issues affecting those groups.

Uses of population census data for monitoring geographical imbalance in the health workforce: snapshots from three developing countries.

BACKGROUND: Imbalance in the distribution of human resources for health (HRH), eventually leading to inequities in health services delivery and population health outcomes, is an issue of social and political concern in many countries. However, the empirical evidence to support decision-making is often fragmented, and many standard data sources that can potentially produce statistics relevant to the issue remain underused, especially in developing countries. This study investigated the uses of demographic census data for monitoring geographical imbalance in the health workforce for three developing countries, as a basis for formulation of evidence-based health policy options. METHODS: Population-based indicators of geographical variations among HRH were extracted from census microdata samples for Kenya, Mexico and Viet Nam. Health workforce statistics were matched against international standards of occupational classification to control for cross-national comparability. Summary measures of inequality were calculated to monitor the distribution of health workers across spatial units and by occupational group. RESULTS: Strong inequalities were found in the geographical distribution of the health workforce in all three countries, with the highest densities of HRH tending to be found in the capital areas. Cross-national differences were found in the magnitude of distributional inequality according to occupational group, with health professionals most susceptible to inequitable distribution in Kenya and Viet Nam but less so in Mexico compared to their associate professional counterparts. Some discrepancies were suggested between mappings of occupational information from the raw data with the international system, especially for nursing and midwifery specializations. CONCLUSIONS: The problem of geographical imbalance among HRH across countries in the developing world holds important implications at the local, national and international levels, in terms of constraints for the effective deployment, management and retention of HRH, and ultimately for the equitable delivery of health services. A number of advantages were revealed of using census data in health research, notably the potential for producing detailed statistics on health workforce characteristics at the sub-national level. However, lack of consistency in the compilation and processing of occupational information over time and across countries continues to hamper comparative analyses for HRH policy monitoring and evaluation.

A model for public health workforce development using the National Public Health Performance Standards Program.

Workforce development programs in public health should link improvements in workers' performance with improvements in their agencies' performance. The "ten essential services" of public health provide criteria for measuring both individual worker training (as in workforce competency standards) and agency performance (as in the Centers for Disease Control and Prevention's National Public Health Performance Standards Program). This shared foundation was the basis for a model strategic training program developed for use in a 500-employee urban county health department. Full implementation of this model as a foundation for assessment, curriculum development, and evaluation requires careful attention to management issues, confidentiality of employee records, and evaluation methodologies.

Enumeration of the public health workforce: developing a system.

Although it has been of interest to public health leaders, advocates, and policy planners for many years, decades have passed since the last organized count of public health workers. This article reports on methods used by the Columbia University School of Nursing, Center for Health Policy, to enumerate the public health workforce in 57 states and territories based on existing reports, summaries, and surveys. The complexity of public health workforce data is described and the scheme utilized to characterize the workforce using public agency categories is illustrated. The resulting "best current estimate" provokes many questions regarding future policy about a public health workforce database.

Prevention Research Centers: contributions to updating the public health workforce through training.

Because public health is a continually evolving field, it is essential to provide ample training opportunities for public health professionals. As a natural outgrowth of the Centers for Disease Control and Prevention's Prevention Research Centers Program, training courses of many types have been developed for public health practitioners working in the field. This article describes three of the Prevention Research Center training program offerings: Evidence-Based Public Health, Physical Activity and Public Health for Practitioners, and Social Marketing. These courses illustrate the commitment of the Prevention Research Centers Program to helping create a better trained public health workforce, thereby enhancing the likelihood of improving public health.

The public health workforce in sub-Saharan Africa: challenges and opportunities.

The health crisis in sub-Saharan Africa (SSA) presents enormous challenges to the public health workforce, which is ill equipped to respond. Since the fate of SSA is central to the health and well-being of all regions, a long-term effort is now required to strengthen the public health workforce in SSA. This will require major support from national governments and a wide variety of international agencies. Several global initiatives present an opportunity for SSA to mount a response to the health crisis. However, unless these resources contribute to the development of infrastructure, human capacity, and management processes, the response is likely to have only a short-term impact on the most pressing health problems.

A history of public health workforce enumeration.

During the 20th century, the United States' public health workforce has been of sufficient interest to policy makers that regular efforts have been made to enumerate it. Limited enumeration is found as early as 1908; the last direct federal survey occurred in 1964. After 1964, workforce size was estimated. The ratio of public health workers to population reached an estimated 220/100,000 in 1980. Data collected in 2000 yielded a ratio of 158/100,000--a 10 percent decrease. In the absence of a system to reliably collect public health workforce data such information is problematic to interpret or use for infrastructure planning and development.

Information needs and uses of the public health workforce--Washington, 1997-1998.

Substantial efforts have been made to ensure that state and local public health agencies have the information technology and training needed for public health communications, information access, and data exchange. Numerous public health-related data and information resources are available on the World-Wide Web (e.g., MEDLINE, MMWR, CDC Prevention Guidelines Database, and Emerging Infectious Diseases); however, little systematic work has been done to understand the information needs of the public health workforce. To identify these needs and patterns of use and to set priorities for developing new online public health information resources, the University of Washington School of Public Health and Community Medicine (UW SPHCM) and the Washington State Department of Health (WSDoH) held structured and facilitated discussions with segments of the local public health workforce in Washington during 1997-1998. This report summarizes the results of those discussions, which indicate that different segments of the public health workforce have different information needs.

The local public health workforce in rural communities.

This work describes the public health workforce and training needs of rural local public health agencies (LPHAs) in comparison with suburban and metropolitan LPHA jurisdictions. A survey was sent to 1,100 LPHAs nationwide. The rural urban commuting area codes (RUCAs) defined LPHAs as rural or urban, and the Standard Occupational Classification system enumerated the workforce. Most occupational classifications had significantly fewer staff in rural LPHAs. Public health nurses ranked as the most needed staff and serve in various important capacities in rural LPHAs. In terms of training, job-specific or programmatic continuing education was identified as the most important training need. Developing leadership and public health workforce capacity within rural public health is an essential agenda item for rural America. Decision makers may need to consider different organizational structures while balancing the need for local input and control. Regionalization and collaborative approaches to difficult workforce issues may present potential solutions to workforce challenges.

Challenges confronting the health workforce in sub-Saharan Africa.

Sub-Saharan Africa and the international health community face a daunting challenge to deal with an extraordinary disease burden and improve the health status of Africans. Despite decades of effort to provide effective, equitable and affordable health care services, the health indices of Africans have stagnated and in some instances have deteriorated. Africa is the only continent that has not fully benefited from recent advances in biomedical sciences that brought health tools and technologies to tackle most of the disease burden. The emergence of the HIV/AIDS epidemic has confounded the health scene and posed further challenges. Several factors are responsible for this state of affairs: macro factors, that represent the broader socio-cultural environment that impact on health, and micro factors, which are largely health sector specific. There is increasing recognition that the major limiting factor to improved health outcomes is not lack of financial resources or health technologies but the lack of implementation capacity which depends on the presence of a functional health system. The drivers and architects of this are health workers, 'the most important of the health system's input'. The Commission on Macroeconomics and Health advocates a greatly increased investment in health rising in low income countries to a per capita expenditure of US $34 per year and states that the problem in implementing this recommendation is not difficulty in raising funds but the capacity of the health sector itself to absorb the increased flow. Yet, until fairly recently sufficient attention has not been directed to the role of the health workforce. The failure to develop and deploy an appropriate and motivated health workforce, and the environment necessary for the workforce to perform optimally is clearly a critical determinant of the health status of Africans. This paper summarizes key issues facing the workforce and outlines a framework to develop strategies to address them.

National health workforce in discrete Indigenous communities.

OBJECTIVE: To identify areas of relative need and inform future planning of health workforce and health services in discrete Indigenous communities. METHOD: Descriptive analysis of relevant variables from the 1999 Community Housing and Infrastructure Needs Survey (CHINS), including all discrete Indigenous communities in Australia. RESULTS: Almost 90% of the Indigenous population of the Northern Territory live in discrete communities. The corresponding figure for Queensland, South Australia and Western Australia is around 25%, for New South Wales 8% and Victoria 1%. Just over 4000 people (5% of the population surveyed) live 100 kilometres or more from the nearest community health centre and almost 60,000 (54%) live 100 kilometres or more from the nearest hospital. Approximately 4000 Indigenous people (6% of population surveyed) have little or no access to a registered nurse or a doctor in their community. Access to Indigenous health workers is also limited, with more than 26,000 people (40%) having almost no access to a male Indigenous health worker and about 10,400 (16%) having almost no access to a female Indigenous health worker. More than 13,000 people (20%) have no access to a dentist and many thousands (30-50%) have no access to allied health or mental health care workers. An obstetrician or ENT/respiratory physician never visited the communities of almost 40,000 people (55% and 59%, respectively) and about 24,000 people (36%) have no access to an ophthalmologist. CONCLUSION: CHINS data provide a unique source of information to monitor the status of health services and the workforce in discrete Indigenous communities.

Positions and training of the indigenous health workforce.

A survey of community-controlled and state health services was conducted in 1995 as part of a needs assessment for a tertiary training initiative in applied epidemiology. Information for 792 Indigenous people in health-related occupations was obtained. Mean time in the current position was 4.8 years, 75% were in designated Aboriginal positions and 44% were health workers. Of the total, 49% had a diploma or certificate, but only 3% had a bachelors degree. The latter compares with 75% of the public health workforce generally which has a bachelors degree or higher. The high proportions of health worker and designated Aboriginal positions, short tenure and low level of degree training suggest that there are a range of employment and training issues which need to be addressed if an appropriate level of Indigenous workforce participation is to be achieved and Indigenous health professionals are to have access to the same vertical and lateral employment mobility as non-Indigenous workers. In particular, there is a huge need to enhance Indigenous participation in health workforce training, and to develop strategies for certification and recognition of the wide range of non-course-based training being undertaken.

Public health workforce development: progress, challenges, and opportunities.

The public health workforce is key to strengthening public health infrastructure. National partners have articulated a vision of a sustainable and competent workforce prepared to deliver essential public health services. Six strategic elements provide a framework for action: monitoring workforce composition; identifying competencies and developing related curriculum; designing an integrated life-long learning delivery system; providing individual and organizational incentives to ensure competency development; conducting evaluation and research and assuring financial support. Partners convened in January 2003 to review progress and to re-evaluate strategies in light of the recently released Institute of Medicine reports on infrastructure and workforce issues. Although significant challenges remain, there is convergence on priorities for competency development, research questions to be addressed and next steps in the national dialogue on certification and credentialing in public health.

A research agenda for public health workforce development.

In the past decades, public health research has focused on categorical rather than cross-cutting or systems issues. Little research has been carried out on the infrastructure required to support public health programs. This article describes the results of an interactive process to develop a research agenda for public health workforce development to inform all those with stakes in the public health system. This research is defined as a multidisciplinary field of inquiry, both basic and applied, that examines the workforce in terms of costs, quality, accessibility, delivery, organization, financing, and outcomes of public health services to increase knowledge and understanding of the relationships among workforce and structure, processes, and effects of public health services. A logic model and five priority research areas resulted from meetings of expert panels during 2000 to 2003. Innovative public and private partnerships will be required to advance cross-cutting and systems-focused research.

Applying risk perception theory to public health workforce preparedness training.

Since 9/11, public health has seen a progressive culture change toward a 24/7 emergency response organizational model. This transition entails new expectations for public health workers, including (1) a readiness and willingness to report to duty in emergencies and (2) an ability to effectively communicate risk to an anxious public about terrorism or naturally occurring disasters. To date, however, research on readiness education for health department workers has focused little attention upon the risk perceptions that may influence their willingness to report to duty during disasters, as well as their ability to provide effective emergency risk communication to the public. Here, we apply risk perception factors to explore the potential barriers and remedies to effective public health workforce emergency response.

Viewpoint: HIV/AIDS and the health workforce crisis: what are the next steps?

In scaling up antiretroviral treatment (ART), financing is fast becoming less of a constraint than the human resources to ensure the implementation of the programmes. In the countries hardest affected by the acquired immunodeficiency syndrome (AIDS) pandemic, AIDS increases workloads, professional frustration and burn-out. It affects health workers also directly, contributing to rising sick leave and attrition rates. This burden is shouldered by a health workforce weakened already by chronic deficiencies in training, distribution and retention. In these countries, health workforce issues can no longer be analysed from the traditional perspective of human resource development, but should start from the position that entire societies are in a process of social involution of a scale unprecedented in human history. Strategies that proved to be effective and correct in past conditions need be reviewed, particularly in the domains of human resource management and policy-making, education and international aid. True paradigm shifts are thus required, without which the fundamental changes required to effectively strengthen the health workforce are unlikely to be initiated.
