3 Background Up to 50% of HIV-infected persons in Europe remain undiagnosed Half of newly diagnosed HIV patients are late presenters Increased HIV testing and improving care pathway are strongly encouraged Only persons linked to care can fully benefit from being diagnosed It is unknown how many diagnosed patients remain outside care Antinori A. Antivir Ther 2010, Mocroft A. PLoS 2013, Wynberg E JIAS 2014

4 Test and Keep in Care (TAK) project Prospective follow-up of HIV persons diagnosed in CBVTC in central Poland Data collection: pre-clinical from CBVTC questionnaire and visits clinical from HIV clinics Main end-point: linkage to care Study aims: estimate the prevalence of HIV-positive persons lost or late to care investigate related factors in order to target effective interventions for linkage to care Ankiersztejn-Bartczak M. HIV Med. 2015

5 Methods data from CBVTC ( ) and HIV clinics were linked using unique Western-Blot number persons tested at CBVTC and registered in HIV clinics databases were linked to care latest follow up date was 4/06/2014

6 HIV clinic Anonymoust testing at CBVTC From CBVTC to HIV clinic Counselling ELISA + result not collected by CBVTC client Lost to care WB+ result not collected by CBVTC client Lost to care Decoding not agree Lost to care Clinic not regisdtered Lost to care Linked to care

7 Methods - Statistical analyses Cox-proportional hazard models were used to identify factors associated with: being linked to care (LTC) baseline date of HIV test starting cart baseline date of first visit to HIV clinic Both pre-clinical (16) and clinical factors were included into analyses and tested as potential predoctors of linkage to care

8 Results linked to care 232 persons tested HIV+ in CBVTC 144 (62.1%) were linked to care (95%CI:60%-70%) 81.2% registered within 3 months from testing Medial follow-up per person 3 months (95%CI:1-23) 239 person years of follow-up * As provided in CBVTC questionnaire

20 Limitations patients classified as lost to care could migrated to or registered at non-regional clinics Rather trend towards centralisation of migration for care it is not possible to perform external quality assurance to exclude double testing in Polish settings (anonymous registration) patients re-test mostly due to undetermined WB result

21 Conclusions Benefits of HIV care, measured by access to early treatment, steadily improved in recent 4 years 1 in 3 persons aware of their HIV status remain outside professional healthcare Bi/heterosexual persons with primary/unknown education are at higher risk of remaining outside care despite being diagnosed

22 Perspectives All CBVTC in Poland record Western blot test numbers as a possible cross-check Next TAK step is introducing targeted intervention in 2015
