Injecting Drug Use and HIV, HCV infections in Dakar, Sénégal : FromResearch to Implementation, the UDSEN project Pierre-Marie GIRARD, Hopital St Antoine & IMEA, Paris and ANRS Sénégal Site, for the UDSEN Study Group
Starting point - ICASA 2008, Dakar • A qualitative RapidAssessmentStudy(2004-2005) confirmed Injectable DrugsUse • The legal and social context of drugs use was repressive. • Very few care giversinvolvedin IDU . • =>PWID/PWUD = hiddenpopulations • Poor experience of HCW on drug use (« drugs » meanonly Cannabis) • Willingness of HIV experts and HCW to face this challenge (CNLS/SMI Fann/Saint Antoine Hospital /ANRS/IMEA /ESTHER). • => Implementation of an Operationnalresearchbased on a prevalence estimation of HIV/HCV/HBV by RespondentDrivenSampling (RDS) method
UDSEN = « Usagers de Drogues Injectables au Sénégal » = « IDU in Dakar area » CEPIAD = « Centre de Prise en charge Integrée des Addictions à Dakar» 2008 2010 2011 2013 2014 2015
UDSEN study: Objectives • To provide objective data on: • IDU prevalence and size of the population • Practices • HIV/HCV/HBV prevalence • HCW and Social Workers training • Advocacy for harmreduction programs • Advocacy for access to HAART in IDU
Ethical Issues • Security & confidentiality for participants : • Setting of the survey in Clinical and Research center of Centre Hospitalier de Fann • Anonymous consent form • Intensive training of HCW and staff members on addictions issues and confidentiality • Amount of incentive: thesame as currentamount for clinicalstudies participation in the center • Care accessfor all the recrutees: • Prevention kits & counselling. • Access to tests results and care = 18-month duration for study preparation
