Can Screening Invitations from Primary Care Physicians Increase Participation in Cancer Screenings on Remote Islands?. Issue 1 (5th July 2013) - Tateno, Yuki
Abstract : Background: Gastric and colorectal cancers are the leading cause of cancer‐related deaths in Japan. In an attempt to control such cancer‐related deaths, gastric and colorectal cancer screenings (GCSs) are readily available in Japan. Despite this, the rate of participation has been lower than expected. Previous studies have reported that some intervention tools can improve participation in cancer screenings and others cannot. Such studies conducted in rural areas are quite rare. Methods: The subjects were residents of Kozu Island. All subjects were aged 40 and over. In the clinical setting, primary care physicians (PCPs) handed their patients a screening invitation, in an attempt to improve participation in GCSs. We examined participation trends before and after this intervention. In addition, we administered questionnaires to examine subjects' reasons for attendance and relevant characteristics of the subjects. Results: Following the intervention, participation in GCSs did not significantly improve in the short term. In 2011, the number of participants in gastric cancer screening was 173 (22.1%) and was not significantly different from the 2010 results (P = 0.80). Furthermore, the number of participants from year to year (2005–2011) was not significantly different (P = 0.07). In addition, the number of participants in colorectal cancer screening was 145 (16.5%) and was not significantly different from the 2010 results (P = 0.65). Moreover, the number of participants from year to year (2005–2011) was not significantly different (P = 0.17). 172 out of 211 (82%) participants submitted the questionnaire. Results taken from the questionnaires showed that our screening invitation influenced non‐elderly people (49.5 ± 3.9 vs. 56.4 ± 6.5, P = 0.04) and first‐attendance people showed a significant tendency for more gastrointestinal symptoms (4 vs. 2, P = 0.03). Conclusion: On the whole, the screening of invitations from PCPs did not improve participation rates in GCSs in the short term. However, we believe that screening invitations can influence non‐elderly people, and this intervention can be effective in increasing the numbers of gastrointestinal‐symptomatic people attending for the first time (first‐attendance people).
