This report aims to estimate the economic cost of providing regular access to healthcare for migrants in an irregular situation, compared with the cost of providing treatment in emergency cases only. Two specific medical conditions – hypertension and prenatal care – were selected as examples, and their associated costs were calculated using an economic model. This model was then applied to three EU Member States: Germany, Greece and Sweden. The testing suggests that providing access to regular preventive healthcare for migrants in an irregular situation would be cost-saving for governments.
