 Within each health care facility selected for the study, all health care professionals providing outpatient care to patients born in sub-Saharan Africa were asked to participate in the study. They identified eligible patients during consultations based on medical records, and offered study participation to all eligible patients, except when the patient was deemed unable to be interviewed for mental health or physical health reasons or because were unable to be interviewed in one of the languages spoken by the interviewer. When the patient agreed to participate in the study, health care professionals gave herhim an information leaflet on the study and obtained written consent. They also gave the participant a card bearing an identification number to ensure data collection anonymity and confidentiality, and referred herhim to the Parcours interviewer at the end of the consultation. The Parcours interviewer conducted the interview right after the consultation, in face-to-face mode, in a dedicated room, with closed door to ensure privacy.
