Free access to medicines is an important element in the implementation of health care access policies. Paradoxically, this aspect is rarely addressed in the literature on this subject. The Ville-Evrard psychiatric hospital introduced so-called "poverty prescriptions" allowing free drug dispensing, independently of specific PASS (Permanent Access to Health_ Care) systems. This paper presents the results of a study of all poverty prescriptions issued by the facility in 2011./t provides an analytical description of this system and shows that, despite the absence of strict controls, it was used relatively rarely.
