To estimate and to compare the cost per woman examined and per breast cancer detected in two mammographic screening programmes in the province of Florence.
Two ongoing, population based, mammographic screening programmes in the province of Florence. The first (district project) was started in the seventies in a rural area, whereas the second (city project) was started in the city at the end of 1990.
All relevant resources consumed by the programmes (costs) were listed and measured. The costs are related to 1993. The unit cost for each phase (recruitment, screening, assessment) of the screening process was estimated by dividing the total cost of the phase by the number of women examined. The cost per cancer detected was obtained by dividing the total cost of the programme by the number of cancers detected at screening.
The costs per woman examined were $38.1 and $41.1 in the district and city programmes respectively. The cost per breast cancer detected was $7424 in the district programme and $5180 in the city programme. Staff accounted for more than 50% of the total cost. The unit cost in the screening phase was higher in the district programme, whereas it was lower in the assessment phase.
Our results are consistent with, although slightly lower than, published estimates of the cost per woman screened. Important parameters for determining the efficiency of a mammographic screening programme are the compliance rate and the recall rate.
评估并比较佛罗伦萨省两个乳腺钼靶筛查项目中每位接受检查女性的成本以及每例检测出的乳腺癌成本。
佛罗伦萨省两个正在进行的、基于人群的乳腺钼靶筛查项目。第一个（地区项目）于七十年代在农村地区启动，而第二个（城市项目）于1990年底在城市启动。
列出并衡量项目消耗的所有相关资源（成本）。成本与1993年相关。通过将筛查过程各阶段（招募、筛查、评估）的总成本除以接受检查的女性人数来估算各阶段的单位成本。通过将项目总成本除以筛查时检测出的癌症病例数来得出每例检测出的癌症成本。
地区项目和城市项目中每位接受检查女性的成本分别为38.1美元和41.1美元。地区项目中每例检测出的乳腺癌成本为7424美元，城市项目中为5180美元。工作人员成本占总成本的比例超过50%。地区项目筛查阶段的单位成本较高，而评估阶段的单位成本较低。
我们的结果与已发表的每位接受筛查女性成本的估计值相符，尽管略低。确定乳腺钼靶筛查项目效率的重要参数是依从率和召回率。
