ABSTRACT
BACKGROUND:
The programme sensitivity is a performance indicator for evaluating the quality of the mammography screening programme (MSP).OBJECTIVES:
We analysed the development of the programme sensitivity over time in two federal states of Germany, North Rhine-Westphalia (NRW) and Lower Saxony (NDS). MATERIALS ANDMETHODS:
Data from 2,717,801 (NRW) and 1,197,660 (NDS) screening examinations between 2006 and 2011 were linked with data of the State Cancer Registry NRW and the Epidemiological Cancer Registry NDS, respectively. Breast cancers (invasive and in situ) were either detected at screening or diagnosed within the 24-month interval after an inconspicuous screening result outside the programme. The crude and age-standardized programme sensitivity was calculated per calendar year. The German mammography screening office provided aggregated recall rates.RESULTS:
The age-standardized programme sensitivity increased markedly for initial screening examinations from 2006 to 2011 from 75.0% (95% CI 72.1-77.9) to 80.5% (95% CI 78.5-82.5) in NRW, and from 74.9% (95% CI 71.4-78.5) to 84.7% (95% CI 81.1-88.3) in NDS. Concurrently, recall rates increased as well. For subsequent screening examinations, the programme sensitivity increased from 2008 to 2011 from 68.1% (95% CI 63.1-73.1) to 71.9% (95% CI 70.2-73.6) in NRW, and from 69.8% (95% CI 64.2-75.4) to 74.9% (95% CI 72.3-77.5) in NDS, whereas the recall rates remained relatively constant.CONCLUSIONS:
In both federal states, the programme sensitivity increased over time. This increase, possibly indicating an improved quality of diagnosis within the MSP as a learning system, is discussed under consideration of the age distribution of screening participants and the recall rates.Palavras-chave
