The supply and geographic distribution
of health workers are major constraints to improving health
in low-income countries. A number of recent studies have
highlighted the shortage of skilled health workers in many
settings (World Health Organization [WHO], 2006), the impact
this has on health outcomes (Anand and Barnighausen, 2004),
and the risk this poses for the achievement of the Millenium
Development Goals (WHO, 2006; joint learning initiative,
2004).
