Interventional study for improvement of lung cancer screening rate

The aim of this study is to evaluate whether leaflet distribution affects lung screening rate, and what factor affects the motivation of consultation. Men and women aged 40 to 59 were targeted to improve screening rate of ages for cancer screening, especially in their prime. Each 1,000 subject, a total of 2,000 were selected and divided into 8 groups in consideration of age group by random sampling method. This group was further divided into two groups, an intervention group including subjects distributed a leaflet and a non-intervention (control) group. A survey was conducted by postal self-administered survey forms. Collection rate was 21.6% for the intervention and 17.6% for the control group. The numbers of respondents who answered that this leaflet was effective for motivation of consulting lung cancer screening and the leaflet was ineffective, were 120 (60.0%) and 80 (40.0%), respectively. This indicated that the leaflet was clearly effective (p 0.01). Actual cancer screening rate was 38.8% for the intervention group and 37.7% for the control group. It was shown that distribution by mail of even a single leaflet made by National Cancer Center was effective for motivation of consultation of lung cancer screening.
