The problems of social inequalities in access to care are major public health issues as recalled by the Regional Health Agency (ARS) of French Guiana in the Regional Health Project (PRS). French Guiana has high precariousness indicators with half of its population living below the poverty line. In addition, health indicators are often more degraded in precarious populations. Thus, in French Guiana, there is a higher rate of premature mortality, partly attributable to obesity, sedentary lifestyle, diabetes and hypertension than in mainland France. Despite an increased need for follow-up of chronic pathologies, the precarious population faces many difficulties in accessing care. The Permanent Access to Health Care (PASS) in Cayenne is a medico-social system, created to respond to these problems. The PASS allows access to monitoring of chronic diseases and support towards the common law healthcare system. Although the phenomenon of non-use of care studied in the precarious population of western French Guiana seems primarily attributable to the absence of social security. The main objective is to evaluate the use of the common law system in hypertensive or diabetic patients treated at the PASS in Cayenne. In addition, the investigators want to study the relationship between integration into the system and the socio-demographic, medical characteristics, understanding of health monitoring.
