Prevention and Control of Viral Hepatitis in Correctional Settings

An Update

on National Recommendations

Why Intervene in Correctional Settings?

Its where the disease is!

  • Thousands of former inmates return to the community each month
    • Correctional health programs provide the opportunity to make prevention and health care services available to a segment of the community with disparities in health outcomes
adult correctional population united states
Adult Correctional Population United States
  • Annually, about 6.5 million adults are in prison, jail, probation and parole
  • Represents about 3.1% of the adult US population -- 1 in every 32 adults
  • About 30% of persons in the correctional system are incarcerated (~1.9 million)

The A, B, Cs of Viral Hepatitis

  • Hepatitis A
    • fecal-oral, spread: person-to-person, drug use, men having sex with men, travelers, day care, food
    • vaccine-preventable
  • Hepatitis B
    • blood and body fluids: sex, drugs, perinatal, occupational, nosocomial
    • vaccine-preventable
  • Hepatitis C
    • blood: drugs, sex, perinatal, nosocomial, occupational
    • NOT vaccine-preventable

immunization recommendations to eliminate hbv transmission in the united states
Immunization Recommendations to Eliminate HBV Transmission in the United States
  • Maternal screening to prevent perinatal infection
  • Universal vaccination of infants
  • Catch-up vaccination of adolescents
    • previously unvaccinated at 11-12 years of age
    • high risk
  • Adults at high risk of infection

hepatitis b immunization recommendations
Hepatitis B Immunization Recommendations
  • “High-risk groups for whom vaccination is recommended include:

Inmates of long-term correctional facilities. Prison officials should consider undertaking screening and vaccination programs directed at inmates with histories of high-risk behaviors.”

Source: MMWR 1991;40 (No. RR-13)

risk factors for acute hepatitis b 1990 1999
Risk Factors for Acute Hepatitis B 1990-1999

Heterosexual activity (38%)

No current

MSM (12%)

IDU (14%)

Other (5%)

Other: occupational exposure, transfusion recipient, hemodialysis, household contact, employee or resident of institution for developmentally disabled

Missed Opportunities for Immunization Against Hepatitis B Virus Infection

  • 39% have been previously incarcerated
  • 2% were incarcerated during their incubation period
  • 70% of IDUs were previously incarcerated

Of reported cases of acute hepatitis B:

hepatitis b vaccination programs in prisons
Hepatitis B Vaccination Programs in Prisons
  • National Survey – 50 States and FBOP
    • 35 respondents, 77% of incarcerated adults
  • Results
    • 2 states offer vaccine to all incoming prisoners
    • 25 states and FBOP offer vaccine to some
    • 9 states offer no vaccine
  • Barriers
    • Cost of vaccine
    • 25 states would offer routine vaccination if funds available

Effect of Hepatitis B Vaccination of Juveniles,

Hampden County, MA

  • Massachusetts began vaccinating juvenile detainees in 1996
    • 1% refuse, 43% completed 3 doses
  • Of entering jail inmates in 2000
    • Vaccine immunity
      • 20 year olds = 40%
      • 40-49 year old = <5%
    • HBV infection
      • 20 year olds = 7%
      • 40-49 year olds = 35%

Hepatitis B Vaccination of Incarcerated Persons

  • Recommended since 1982
  • Prevents infection outside and inside of facilities
  • Feasible
  • Cost-effective
  • Anticipated impact on the entire community
  • A number of challenges to implementation
    • Juveniles = covered under Vaccines for Children (VFC) program
    • Adults = no national programs
sources of infection for persons with hepatitis c

Injecting drug use 60%

Sexual 15%

Transfusion 10%

(before screening)

Other* 5%

Unknown 10%

Recommendations to Identify Persons with HCV Infection

  • Identify persons at risk for HCV and test to determine infection status
    • Identify at-risk persons through history, record review
  • Provide HCV-positive persons
    • Medical evaluation and management
    • Counseling
      • Prevent further harm to liver
      • Prevent transmission to others

hepatitis c recommendations
Hepatitis C Recommendations

“Testing persons in settings with potentially high proportions of IDUs (e.g., correctional institutions…) might be particularly efficient for identifying HCV-positive persons”

  • HCV infected persons who abuse substances should be offered substance abuse treatment
health education post release management
Health Education & Post-Release Management

  • Consider offering as part of HIV curriculum
  • Necessary Components:
    • How to prevent acquiring infection
    • Where to go for vaccine series completion
    • For infected persons
      • How to prevent infecting others
      • How to prevent further liver damage
