Oppression, liberation, wellbeing, and ecology: organizing metaphors for understanding health workforce migration and other social determinants of health.

BACKGROUND: The Commission on Social Determinants of Health (CSDH) identifies the maldistribution of power, money, and resources as main drivers of health inequities. The CSDH further observes that tackling these drivers effectively requires interventions to focus at local, national, and global levels. Consistent with the CSDH's observation, this paper describes the eco-psychopolitical validity (EPV) paradigm, a multilevel and transdisciplinary model for research and action, thus far insufficiently tapped, but with the potential to systematize the exploration of the social determinants of health. RESULTS: Using the physician migration from Sub-Saharan Africa (SSA) to the United States as illustration, this paper articulates how the EPV model can be applied to the systematic analysis of a complex social problem with health inequity implications. To help explore potential determinants of physician migration, a comprehensive coding matrix is developed; with the organizing metaphors of the EPV model-namely oppression, liberation, and wellbeing-serving as analytical categories. Through the lens of the EPV model, migrating physicians are revealed as both ecological subjects enmeshed in a vast web of transnational processes linking source and destination countries, and potential change agents pursuing liberation and wellbeing. While migration may expand the opportunities of émigré physicians, it is argued that, the pursuit of wellbeing by way of migration cannot fully materialize abroad without some efforts to return home, physically or socially. CONCLUSION: Clarifying the relationship between various social determinants of health and health inequities at different levels of analysis is a more complex but essential endeavor to knowledge generation than using a one-dimensional frame. With its roots in interdisciplinary thinking and its emphasis on both individual and contextual factors, the EPV paradigm holds promise as a model for examining the social determinants of health.

Monitoring Sub-Saharan African physician migration and recruitment post-adoption of the WHO code of practice: temporal and geographic patterns in the United States.

Data monitoring is a key recommendation of the WHO Global Code of Practice on the International Recruitment of Health Personnel, a global framework adopted in May 2010 to address health workforce retention in resource-limited countries and the ethics of international migration. Using data on African-born and African-educated physicians in the 2013 American Medical Association Physician Masterfile (AMA Masterfile), we monitored Sub-Saharan African (SSA) physician recruitment into the physician workforce of the United States (US) post-adoption of the WHO Code of Practice. From the observed data, we projected to 2015 with linear regression, and we mapped migrant physicians' locations using GPS Visualizer and ArcGIS. The 2013 AMA Masterfile identified 11,787 active SSA-origin physicians, representing barely 1.3% (11,787/940,456) of the 2013 US physician workforce, but exceeding the total number of physicians reported by WHO in 34 SSA countries (N = 11,519). We estimated that 15.7% (1,849/11,787) entered the US physician workforce after the Code of Practice was adopted. Compared to pre-Code estimates from 2002 (N = 7,830) and 2010 (N = 9,938), the annual admission rate of SSA émigrés into the US physician workforce is increasing. This increase is due in large part to the growing number of SSA-born physicians attending medical schools outside SSA, representing a trend towards younger migrants. Projection estimates suggest that there will be 12,846 SSA migrant physicians in the US physician workforce in 2015, and over 2,900 of them will be post-Code recruits. Most SSA migrant physicians are locating to large urban US areas where physician densities are already the highest. The Code of Practice has not slowed the SSA-to-US physician migration. To stem the physician "brain drain", it is essential to incentivize professional practice in SSA and diminish the appeal of US migration with bolder interventions targeting primarily early-career (age ≤ 35) SSA physicians.

Physician emigration from sub-Saharan Africa to the United States: analysis of the 2011 AMA physician masterfile.

BACKGROUND: The large-scale emigration of physicians from sub-Saharan Africa (SSA) to high-income nations is a serious development concern. Our objective was to determine current emigration trends of SSA physicians found in the physician workforce of the United States. METHODS AND FINDINGS: We analyzed physician data from the World Health Organization (WHO) Global Health Workforce Statistics along with graduation and residency data from the 2011 American Medical Association Physician Masterfile (AMA-PM) on physicians trained or born in SSA countries who currently practice in the US. We estimated emigration proportions, year of US entry, years of practice before emigration, and length of time in the US. According to the 2011 AMA-PM, 10,819 physicians were born or trained in 28 SSA countries. Sixty-eight percent (n = 7,370) were SSA-trained, 20% (n = 2,126) were US-trained, and 12% (n = 1,323) were trained outside both SSA and the US. We estimated active physicians (age ≤ 70 years) to represent 96% (n = 10,377) of the total. Migration trends among SSA-trained physicians increased from 2002 to 2011 for all but one principal source country; the exception was South Africa whose physician migration to the US decreased by 8% (-156). The increase in last-decade migration was >50% in Nigeria (+1,113) and Ghana (+243), >100% in Ethiopia (+274), and >200% (+244) in Sudan. Liberia was the most affected by migration to the US with 77% (n = 175) of its estimated physicians in the 2011 AMA-PM. On average, SSA-trained physicians have been in the US for 18 years. They practiced for 6.5 years before US entry, and nearly half emigrated during the implementation years (1984-1999) of the structural adjustment programs. CONCLUSION: Physician emigration from SSA to the US is increasing for most SSA source countries. Unless far-reaching policies are implemented by the US and SSA countries, the current emigration trends will persist, and the US will remain a leading destination for SSA physicians emigrating from the continent of greatest need.
