Disparities in HIV and HCV InfectionDisparities in HIV and HCV Infection

Racial Disparities in HIV InfectionRacial Disparities in HIV Infection• African Americans represent 14% of the

population and 45% of HIV infections• African Americans are more likely to present

later in the course of their infection and have higher rates of AIDS-related mortality

• Traditional behavioral risk factors don’t explain disparities– More limited access to HIV testing, lower insurance

rates– Structural and social factors – Complex sexual networks

Geographic DisparitiesGeographic Disparities

• In many urban areas, a few neighborhoods account for a large share of HIV infections

• HIV infections cluster• Some neighborhoods have

HIV infection rates similar to sub-Saharan Africa

• Maps tell us where to focus intensive prevention and treatment efforts

• Philadelphia has infection rates 5 times the national average• Heterosexual epidemic• Zipcode 19143 (in Southwest Philadelphia) is the second most

populous zipcode in the city (60,000 people)– 86% African American, 30% people < poverty line

• Zipcode 19143 has the 2nd highest number of people living with HIV/AIDS (1,014 individuals in 2010)– Approximately 1.8% seropositivity

• Rates of Hepatitis C (HCV) in 19143 unknown, but likely high• 19143 has few medical and health resources

Do One Thing OverviewDo One Thing Overview

• Southwest Philadelphia, PA is a medically underserved area with high rates of HIV and HCV infection & few HIV and HCV testing & treatment services

• Do One Thing is a testing, linkage to care and treatment campaign that stimulates demand for and provides HIV and HCV testing and treatment across an entire zipcode

• Do One Thing includes:• A large-scale social marketing and media campaign• Community outreach and mobilization • Partnerships with business, community organizations, and faith institutions• A partnership with a federally qualified health center in Southwest Philadelphia

to routinely offer HIV testing to all patients over age 13• Rapid HIV and HCV testing in a mobile unit, door-to-door testing in 4 census

tracts• Community service and volunteerism• Monitoring and evaluation

Victories and Challenges with Victories and Challenges with Routine Testing in Clinical SettingRoutine Testing in Clinical Setting

Clinical Challenges and Lessons learned• Policy Change: Leadership is most important factor• Integrated Model: Know your patient flow and model

– NP clinical model with MAs testing model

• EMR Enhancement• Staff and Provider Training• Financial incentives

Victories and Challenges with Victories and Challenges with Routine Testing in Clinical SettingRoutine Testing in Clinical Setting

Clinical Challenges and Lessons learned• Offer rate has plateaued at 70%

– Next step: incentivize acceptance rate improvements

• High decline rate: most commonly cited reasons are “recently tested” and “wasn’t expecting an HIV test”

• Behavioral risk profiles: most new positives have “no identified risk;” most are young, African American women

• Lower seropositivity than expected: 0.4%• 95% linkage and retention in care rate; has been

sustained over time

Clinical and Non-Clinical Clinical and Non-Clinical HIV Testing TrendsHIV Testing Trends

• Clinical Settings

– Tested 2,100 people for HIV in clinical settings

– Health Annex (FQHC) seropositivity: 0.4%

– Greatest challenge: 55% decline rate

• Non Clinical Settings

– Tested 900 people for HIV in non-clinical settings

• 1.3% HIV seropositivity

– Tested 350 people for HCV in non-clinical settings since December 2012

• 4.8% HCV seropositivity

Demographic Trends of HCV positive Demographic Trends of HCV positive Patients in non-clinical SettingPatients in non-clinical Setting

• Continuing Quality Improvement (CQI) is critical • Many are known HIV and HCV positive and not in care• Comprehensive campaign is a way to raise awareness,

fight stigma and re-engage patients in care • Biggest challenge in non-clinical setting: retaining HIV

patients in care• Biggest HCV challenge: payment and linkage

– insurance and referrals for HCV care

Lessons Learned and ImplicationsLessons Learned and Implications

• Biggest challenge in clinical setting: high decline rate• 74% of patients testing for HIV at clinic were women; men

more frequently decline HIV testing in clinical setting• More new diagnoses in clinical settings than non-clinical

settings• Offering HIV and HCV testing together may enhance testing

rates• Street and door to door outreach is effective, especially for

reaching youth and men• High HCV seropositivity rate; few clients are in care• Volunteers reduce staff costs and enhance sustainability

Surprising FindingsSurprising Findings

WhatWhat is next?is next?• Enhancing routine testing at FQHC

– Boost our offer rate and reduce our decline rate • Develop a complete neighborhood-based diagnosis,

treatment and care cascade• GIS mapping of hotspots for HIV and HCV• Trial comparing control and treatment neighborhoods• Cost-effectiveness study• Complete program evaluation, including improvements

from baseline• Mapping transmission using HIV sequences at

neighborhood level
