title: Cost-effectiveness of hepatitis A/B vaccine versus hepatitis B vaccine in public sexually transmitted disease clinics.
abstract: BACKGROUND
  Many patients seen at U.S. sexually transmitted disease (STD) clinics are offered hepatitis B vaccination. Substituting hepatitis A/B vaccine would provide additional protection but increase costs.
  
  
  OBJECTIVE
  The goal was to estimate the cost effectiveness of hepatitis A/B versus B vaccination for 1,000,000 public STD clinic attenders.
  
  
  METHODS
  A Markov model of hepatitis A outcomes was developed using published literature, U.S. government databases, and expert panel opinion. Added vaccination costs were compared with savings from reduced hepatitis A treatment. Net costs were compared with life-years saved and quality-adjusted life-years (QALYs) gained.
  
  
  RESULTS
  Substituting hepatitis A/B vaccine would prevent 2263 overt hepatitis A infections, 292 hospitalizations, 8 premature deaths, and the loss of 281 QALYs. Net health system costs would be $20,892 per life-year saved, or $13,397 per QALY gained.
  
  
  CONCLUSIONS
  Substituting hepatitis A/B for hepatitis B vaccine would reduce morbidity and mortality in a cost-effective manner.
