The metrics and correlates of physician migration from Africa
This article describes different method of measuring the relative importance of health workers' migration and draws policy recommendations from the implications of the adoption of different measurement methodologies.
Higher physician migration density was seen among African countries with relatively higher health workforce capacity, health status, health spending, and development.
The perceived magnitude of physician migration is sensitive to the choice of metrics. Complementing the emigration fraction, the physician migration density is a metric which gives a different but proportionate picture of which African countries stand to lose relatively more of its physicians with unchecked migration.
