Cuban medical professionals who have served in Cuba’s medical mission to Venezuela (Barrio Adentro) have reported fraudulent overstatement of the mission’s statistics.
Venezuela pays Cuba on the basis of the number of patients the medical professionals treat or the educational workshops they teach. As a result, the Cuban authorities do not want low numbers of such patients to affect their income and, therefore, set daily quotas for the number of patients that are seen and treated.
According to some Cuban dentists and ophthalmologists in particular, they were unable to meet their quotas and, therefore, regularly submitted reports that falsely overstated the number of patients they had seen.
