Summary • Surveillance nightmare • Incidence declining, difficult to measure • Large burden of chronic disease • Prevalence in PWID much higher than for HIV • Concomitant psychosocial issues present huge barriers to diagnosis and management

Question Which of the following are ways you could provide support to integration of HIV/viral hepatitis/STD service delivery in your agency? A. Collaborate with managers in other divisions B. Cross-train staff to support integrated work activities C. Develop low-impact methods of one-stop-shop public health interventions that work for our diverse service delivery programs D. All of the above
One-stop-shop for core public health services for persons at risk for HIV, viral hepatitis, STDs, and TB ‘HIV, Hepatitis, STD’ Say it like it’s one word! PCSI Bottom Line
Surveillance Programs HCV screening Hepatitis A/B vaccine to high-risk adults Integration with HIV, STI, TB (when appropriate) Targeting the highest-risk adults in Oregon HCV and Public Health Interventions: State Focus
Marion County STI routinely clinic screens for hepatitis vaccine for adults Vaccines are administered by immunization nurses at time of STI appointment On-demand HIV and HCV testing are provided through the HIV prevention section Innovative Approaches Example: Marion County, Oregon
June 2004 through October 2004 86 client records tracked in study log Age = 25.8 85% had insurance that could be billed 89% of vaccine eligible clients received verbal recommendation from nurse provider 64% received vaccine Outcomes
Close proximity of services (STI next door to Immunology, HIV prevention down the hall) Sticker “tickler” system Pre-project communication and brainstorming Cross-training of administrative, nursing, and health education staff Supports to Integrated Service Delivery
Remembering to screen each client at STI clinic (administrative) Unknown if single antigen or Twinrix indicated (administrative) Vaccine Administration Record completion (nurse) Learning new vaccine protocols (nurse) Barriers to Integrated Service Delivery
NEX outreach van 1 x per week under bridge in semi-rural area: Medical provider: wound care Nurse practitioner: Twinrix A/B vaccine HCV screening: home access kits HIV testing: Orasure Referral services to actual people, not just agencies Innovative Approaches Example: HIV Alliance, Eugene, Oregon
Very feasible if just one person willing to be the shameless instigator to instigate integration Precedent set in urban and rural settings Cross-training of staff is necessary given ongoing public health budget cuts in Oregon (e.g., timber fund cuts) Feasibility of PCSI in Oregon Local Health Departments
The only way to address the HCV epidemic is through integrated service delivery options like comprehensive services at LHDs and holistic health services through NEX programs. Test! Educate! Vaccinate! Bottom Line of HCV Innovation: Moving Past Our Silo-ized PH Delivery Systems!
