Abstract:
Background/Aims:Postal distribution of a fecal immunochemical test (FIT) kit has been recommended as an effective method of increasing participation in colorectal cancer (CRC) screening. The present study was performed to assess the impact of the round-mailed FIT kit on screening participation in underserved regions of Korea and to identify factors related to nonparticipation.
Methods:Residents were recruited from three rural regions of Korea that lack screening units for the National Cancer Screening Program. A package containing a FIT kit for stool self-sampling and a return envelope addressed to the local health center was postally distributed to each subject. Thirty days after the kits were mailed, nonresponders were reminded via telephone as the second intervention. The participation rates and odds ratios with 95% confidence intervals (CIs) for each intervention response were calculated to evaluate the effect of the interventions and factors related to screening participation in response to the interventions.
Results:CRC screening participation rates increased from 24.5% (95% CI, 21.6% to 27.4%) to 42.6% (95% CI, 39.3% to 46.0%) as a result of postal screening and increased further to 51.4% (95% CI, 48.0% to 54.9%) after the telephone reminder. After controlling for the sex, age, and household type of each subject, factors associated with poor response to postal screening were identified as low educational attainment and poor previous participation in the National Cancer Screening Program.
Conclusions:Round-mailed FIT kits with phone call reminders were an effective intervention, nearly doubling the screening rate in underserved regions of Korea.
