Until now, incomplete and out-of-date health workforce data has made it difficult for Haiti’s Ministry of Health (MSPP) to address this challenge. The last known census of the health workforce occurred in 2008, before the 2010 earthquake that devastated Haiti’s already fragile public health infrastructure. Without reliable health workforce data, the MSPP’s Directorate of Human Resources (DRH) could not develop an evidence-based strategy to address the lack of qualified health professionals nationwide and thereby improve the Haitian population’s access to quality health services.
