6 Late presenters in Europe  Most patients infected with HIV across the Europe remain undiagnosed; this percentage varies markedly from 15-80% across the continent.  Undiagnosed HIV is harmful to the person infected as appropriate health interventions are then delayed until the HIV infection is diagnosed.  It is also detrimental to society as persons unaware of their HIV infection may transmit more frequently to others than persons that are aware of their HIV status.  Finally, late presentation is associated to increased medical costs

9 9 CDC Recommendations for HIV Testing in Healthcare Settings  Routine voluntary testing for patients ages 13 to 64 years in healthcare settings –Not based on patient risk  Opt-out testing –No separate consent for HIV –Resulting in increases in HIV testing rates  Pretest counseling not required  Repeat HIV testing left to discretion of provider, based on risk  Within the US, 34 states are neutral to supportive of the CDC guidelines while 11 states have taken steps to reduce regulatory barriers –6 states passed legislation (2007) Branson BM, et al. MMWR Recomm Rep. 2006;55(RR-14):1-17.

10 10 Hader, S, 16th CROI 2009; 57 Washington DC HIV Testing Expansion: Earlier Diagnosis Helps Identify HIV+ People at Higher CD4+ Counts  Expanding HIV testing in jails, schools, needle exchange, and couples services  Through these efforts they were able to increase the number of tests given from 43,271 tests done in 2007 to 72,864 tests done in 2008 (68.4% increase)  In addition, they were able to find patients with higher CD4 counts at initial testing –2004 – 198 cells/mm 3 –2007 – 332 cells/mm 3 Year of HIV Diagnosis Median CD4 Count 215 183 187 198 220 262 332 0 50 100 150 200 250 300 350 2001200220032004200520062007 Median CD4 Count at Time of Testing

12 Indicator Disease-guided testing for HIV 2. Indicator disease-guided testing The ‘HIV in Europe’ Conference (2007) recommended further development of focused HIV testing in patients presenting with certain clinical conditions and/or diseases (i.e. the indicator disease testing guidelines). Cost effectiveness analysis suggests cost savings if a population with a HIV prevalence of 1% or more are tested although this rate may be as low as 0.1%.

19 Indicator disease surveys Aim: a survey initiative to assess HIV prevalence for one or more diseases within a segment of the population not yet diagnosed with HIV and that present for care with the specific disease/condition. Conduct: 2 phases (pilot and 2 nd ) Pilot: –25 surveys within a specific segment of the population –On consecutive patients not yet known to be HIV-infected –Have one of 8 conditions until 200 (300-400) have entered –Harmonized and central data capture Evaluation 2 nd phase

20 Pilot- Phase I 1.Sexually transmitted diseases 2.Malignant lymphoma, irrespective of type 3.Cervical or anal dysplasia or cancer, 4.Herpes zoster in a person younger than 65 years, 5.Hepatitis B or C virus infection 6.Ongoing mononucleosis-like illness 7.Unexplained leukocytopenia or thrombocytopenia lasting at least 4 weeks 8.Seborrheic dermatitis / exanthema Survey initiative to assess HIV prevalence for 8 conditions within a specific segment of the population not yet diagnosed with HIV and that present for care.

31 31 Recommendations for Target HIV Testing in Healthcare Settings (Indicator disease-guided)  All individuals with diseases recognized to be associated with HIV (prevalence > 0.1%) should be tested for HIV  All HCPs across Europe should be aware of the need to test more individuals for HIV  Some healthcare providers such as GPs, OBGYN, dentists, dermatologists, STD clinicians and ER physicians should particularly be targeted because they are likely to be the providers who first encounter HIV-infected patients presenting comorbid conditions  All individuals attending STD clinics should be offered an HIV test on an annual basis  European governments should consider the utility and cost-effectiveness of adopting opt-out testing for all pregnant women Gazzard B, et al. HIV Medicine (2008), 9 (Suppl. 2), 34–40

32 Considerations How do we ensure that all health systems across Europe target persons presenting with an AIDS-defining disease for HIV testing? How do we establish HIV indicator disease guided testing as appropriate standard of care across Europe? What role should HIV in Europe play in identifying the target group for information and ensuring communication to this group? What is the link between current testing policies/guidelines and indicator disease guided testing?

33 How do we ensure that all health systems across Europe target persons presenting with an AIDS- defining disease for HIV testing? In the current situation many patients with AIDS are not necessarily tested for HIV It is important to identify physician’s barrier to testing In order to achieve this, we need a Country specific analysis of non-HIV-specialised care providers involved in patients who present wth AIDS defining diseases It is important to ensure systems based on principles of human rights protection Implementation of Guidelines formulating this approach to testing and subsequent monitoring and evaluation

34 What do we mean by indicator disease? A disease indicating that a HIV test should be considered/performed AIDS defining events Diseases associated with high HIV prevalence Diseases with Implications for management Differential diagnosis

35 AIDS defining diseases Any diseases = with HIV prevalence higher than.0.1-1% Implication for the individual clinical management HIV considered for differential diagnosis PCP KS ….. ? Hepatitis ? VZV …. Cancer Transplantation …. Guillant Barré, multiple sclerosis … Strongly recommend testing Strongly recommend testing Offer testingConsider testing Indicator disease guided testing

36 How do we establish HIV indicator disease guided testing as appropriate standard of care across Europe? Current Indicator Diseases Survey will help to determine prevalence of HIV among 8 selected non- AIDS defining diseases Country-based test recommendations should be based upon Country-specific HIV prevalence of these diseases Testing for HIV has to be effective/useful in terms of all aspects of medical care including ART Widespread routine testing for less prevalent indicator diseases might require demonstration of cost- effectiveness depending on Country specific policies

37 What role should HIV in Europe play in identifying the target group for information and ensuring communication to this group? HIV in Europe should continue to assemble HIV advocates, policy makers and HIV care providers in open discussion Efforts should be made to reach a wide range of medical disciplines involved in indications for HIV testing

38 What is the link between current testing policies/guidelines and indicator disease guided testing? Standards of current testing policies to be maintained particularly while preserving human rights Indications for HIV testing will be added (see table) Any indication for HIV testing is complementary to current guidelines/policies
