The cost-effectiveness of the cytology laboratory and new cytology technologies in cervical cancer prevention

The effect of changes in cytology laboratory costs, including the costs of new technologies, on the cost-effectiveness of cervical cancer prevention h as not been studied. Using University of Iowa laboratory detection rates an d costs, a decision model determined the cost-effectiveness of the laborato ry with and without new technologies. Compared with not performing a cervic ovaginal smear the cost to increase the discounted life expectancy per pati ent by I year was $2,805 for the laboratory component alone and $19,655 for the entire cervical cancer prevention strategy. In moderate- to high-risk women, cervical cancer screening was cost-effective even at high cytology l aboratory costs leg, $75 per smear). New technologies were cost-effective o nly if they resulted in a substantial increase in the detection of high-gra de squamous intraepithelial lesions leg, an additional 236 high-grade squam ous intraepithelial lesions per 10,000 women). New technologies have not de monstrated these increased detection rates.
