Description

The purposes of this study are to evaluate the effect on the screening rate by questionnaire survey conducted before the cancer screening begins, and to clarify the problem when estimate the screening rate of the population on the data of the examination situation of postcard survey respondents. The data of questionnaire and postcard survey obtained from our previous research where men and women aged ４０ to ５９ years old for lung cancer screening （population screening by municipality “A” city, and occupation-related and opportunistic screening）of１９，００６ were targeted and ２０００ （questionnaire group） were selected by random sampling method, was newly analyzed again. The difference of population screening rate between a questionnaire group and a non-selected group was compared. And occupation-related and opportunistic screening rate was estimated by postcard survey after screening. The population screening rate of １４．５％ for questionnaire group was significantly higher than that for non-selected group of ６．７％ （p＜０．０１）. The occupation-related and opportunistic screening rate was estimated by the postcard reply, and the rate was９．０％ for questionnaire group. The rate was significantly higher than ４．２％ for non-selected group （p＜０．０１）. The consultation number of population screening by postcard reply （６０ persons） was almost corresponding to the actual number by municipality survey （６１persons）. Then the rate by postcard reply was ５４．１％ and was about ４ times compared with the actual screening rate. It might be indicated that only a questionnaire survey affected screening rate because the screening rate for questionnaire group was significantly higher than that for non-selected group. And because almost every consulted people replied to the postcard, the estimated screening rate by postcard survey was affected by collection rate. Occupation-related and opportunistic screening rate could be estimated depending on the analysis of questionnaire result.
