[BDSP. Notice produite par INIST c26YR0xT. Diffusion soumise à autorisation]. Context-Rotavirus is the most common cause of severe diarrhea in children, and a live, oral vaccine may soon be licensed for prevention. Objective-To estimate the economic impact of a national rotavirus immunization program in the United States. Design-Cost-effectiveness was analyzed from the perspectives of the health care system and society. A decision tree used estimates of disease burden, costs, vaccine coverage, efficacy, and price obtained from published and unpublished sources. Intervention-The proposed vaccine would be administered to infants at ages 2,4, and 6 months as part of the routine schedule of childhood immunizations. Main Outcome Measures-Total costs, outcomes prevented, and incremental cost-effectiveness. Results-A routine, universal rotavirus immunization program would prevent 1.08 million cases of diarrhea, avoiding 34 000 hospitalizations, 95 000 emergency department visits, and 227 000 physician visits in the first 5 years of life. At $20 per dose, the program would cost $289 million and realize a net loss of $107 million to the health care system-$103 per case prevented. The program would provide a net savings of $296 million to society. Threshold analysis identified a break-even price per dose of $9 for the health care system and $51 for the societal perspective. Greater disease burden and greater vaccine efficacy and lower vaccine price increased cost-effectiveness. (...)
