Who are you routinely testing for HIV in your practice?
1. Sexual partners of your HIV- infected patients
2. HIV-uninfected patients in your practice who
present with a new std
3. HIV- uninfected patients in your practice who
present with tuberculosis
4. HIV-uninfected patients in your practice with a fever
of unknown origin
5. All patients in your practice aged 13-64 years old
who have never been tested for HIV?

   September 22, 2006 CDC Recommendations:
           Routine Testing for HIV-1

                                  • Routine voluntary testing for
                                    patients ages 13-64 in
                                    healthcare settings – not
                                    based on patient risk

                                  • Opt-out testing

                                  • No separate consent for HIV

                                  • Pretest counseling not

                                  • Repeat HIV testing left to
                                    discretion of provider, based
                                    on patient risk

 Late HIV Testing Is Too Common
• Among 4,127 persons with AIDS1, 45% were first
  diagnosed HIV + within 12 months of AIDS diagnosis
• Late testers, compared to those tested early
  (> 5 yrs before AIDS dx.) were:
       – Younger, heterosexual, less educated, of color
• Late testers have increased mortality
       – In NYC, 25% pts diagnosed with AIDS with first HIV test
           • Median survival post-AIDS is 4 months2
• Mean survival 24.2 years when therapy initiated
  before CD4 < 200 cells/mm3

            prompted an HIV test

      Normalizing Routine HIV                Slide #13

       Testing: Key Strategies

• Increase opportunities for testing
  Make HIV testing routine part of medical care
• Utilize accurate, rapid tests
  Provide new opportunities for early diagnosis
• Normalize HIV testing
  Help identify infections and triage into care
• Promote awareness of serostatus
  Help prevent new infections
  Prevention for positives
           Challenges for Routine
                                                 Slide #14

            Opt-out HIV Testing
• Stigma and discrimination
    Normalizing testing could decrease
• Patient awareness
    Provider responsibility to inform, educate
•   Lose possible benefit of counseling
•   Perceived coercion, privacy, civil liberties
•   Legal issues
•   Resources to pay for more testing and care
•   Insurers’ disincentive to know

    and Demographic Realities

• PLHIV compared to general US population
  – Unemployed                  62% vs 5%
  – Income < $10,000/yr         45% vs 8%
• Source of insurance for PLHIV
  – Medicaid or Medicare        50%
  – Uninsured                   20%
• Ryan White Care Act
• Demographics of new infections
  – African Americans, MSM, young people

HIV Testing: Legal Considerations

•   Issues concerning HIV testing policies vary by state,
    insurer, and sometimes employer
       eg, Medicare, military
       Confidentiality and access to care are governed by a
        wide range of federal and state laws
•   Title VII of the Civil Rights Act prohibits discrimination
       Concern that greatly expanded testing will test more
        people of color without an increase in linkage to care
•   Ethical considerations
       Public health ethics dictate that the primary beneficiary
        has to be those who are screened
       Programs must include sufficient $ and case
        management to ensure access to care
                                                  Slide #18

HIV Testing: Legal Considerations

• Testing HIV + has implications that can
  affect people’s livelihood and legal status
   Federal agencies may exclude or restrict
    employment/licensing of people with HIV
   Restrictions on the practice of HIV+ HCW
   Criminalized sexual activity of people with PLHIV
• Current HIV testing laws protect providers
  from liability as well as patients
• New guidelines may require amending some
  state laws
                                        Slide #19

  Opt-Out and Informed Consent

• Written informed consent is a legal
• Patient education is an ethical and clinical
• Locally specific training needed for HCW to
  adapt new testing and consent
• Informed consent can be secured in a
  number of ways, with modest time
• Chart documentation can be helpful
                                                                     Slide #20

 Routine HIV Testing in Hospitals

• Inpatient HIV testing is cost effective
 - Without routine screening, 53% of HIV diagnoses are
    because of opportunistic infections
 - This can be reduced to 38% with routine screening
• Testing costs don’t matter
 Cost-effectiveness of HIV screening is linked to the
 costs of providing care, not the test cost
• Importance of linkage to care
 Testing programs that have higher rates of linking
 patients to care are more economically efficient than
 those that only test.*

   Opt-Out HIV Testing: Operational
Challenges in the Emergency Department

• EDs serve as a safety net with a large
  volume of patientsoften minority,
  uninsured, substance users
• Relatively high prevalence of HIV
  infection among patients in EDs
  (roughly 10% at Johns Hopkins ED)
• Pts may wait for long periods:
  opportunity for education about testing
• New educational approaches are being
  studied, e.g. videos

The Community Health Center (CHC)
 Perspective: Issues and Challenges
• Health centers provide ¼ of all
  ambulatory care for uninsured patients
• CHCs have higher HIV prevalence
  2.4% vs 1.2% at all testing sites
• Highest rate of follow-up with 95% of
  clients receiving test results
• Challenges: access to primary care
  providers, HIV specialists, HIV
  medications, and funding
• Routine HIV testing will further stress
  CHC system

• University of Alabama, Birmingham

• HIV Medicine Association: 2006 survey of 800
  clinics with 500-1500 patients
   – 40% report difficulty recruiting physicians
   – 85% had < 25% capacity to increase

      Ensuring Access to HIV Care
• $ distributed by local AIDS/HIV prevalence
  –   Discretionary program to fill gaps
  –   72% racial minorities, 33% women
  –   79% uninsured/underinsured, and/or public aid
  –   40% for drugs; 25% for medical care

• Challenges
  –   Increasing demand with growing HIV prevalence
  –   Prioritizing primary care services
  –   “Robbing Peter to pay Paul”
  –   Expanding access to life-saving medications
     Medicare and Medicaid:
                                               Slide #26

 Reimbursement for HIV Testing
   Largest source of federal $ for HIV care
   Covers 50% PLHIV
   Routine testing is optional under federal law
   Testing policies are state-dependent
   Adding new testing requires Congress
   Routine HIV screening would apply only to
    6.8 million receiving disability beneficiaries

 What Happened and What Would Have Happened
      Without Prevention Services in Place?

   Optimizing HIV Prevention Interventions

• Individual, small group, and community
  based interventions decrease HIV risk
• HIV risk behavior and infection occurs in a
  context of other psychosocial problems2
• To be maximally effective, interventions
  should address substance use, depression,
  past abuse, and violence

1. Information/education (not sufficient itself)
2. Motivation enhancement
3. Skills training
4. Social cognitive theory: increase self-efficacy
5. Theory of reasoned action: change norms and
6. Health belief model (benefits and barriers to
   health behaviors, perceived susceptibility)
7. Transtheoretical model (stages of change)

    Routine Opt-Out Testing for HIV:
     Questions for the Road Ahead
• Are sufficient systems in place to ensure non-
  coercion, non-discrimination?
• Can barriers to routine testing be removed?
• Will the influx of newly diagnosed patients have
  access to care and treatment?
• Will the dramatic increases in funding required
  to increase clinical capacity be provided?
• Can care and prevention be optimized if
  comprehensive HIV primary care is not funded?
• Will we have sufficient numbers of skilled
  professionals to do the work?
                                                Slide #31

Routine HIV Testing: Conclusions

• Benefit of HIV treatment is evidence-based
    Reduces morbidity and mortality
      Early treatment better than late treatment
   Is cost-effective
• HIV diagnosis is too often late
•   HIV+ aware people may be less likely to transmit
•   HIV tests are improved (near perfect) and rapid
•   Routine HIV testing is cost-effective
•   Routine testing = fewer missed opportunities
•   But, even among those who know HIV status
    and are in care, 50% of those who need HAART are
    on treatment
