Impact of SMS Messaging on Participation in Colorectal Cancer Screening
Impact of SMS Notifications on the Colorectal Cancer Screening Program
調査の概要
詳細な説明
This study is a pragmatic, randomized, parallel-group clinical trial with a 1:1 allocation ratio, conducted within the framework of the Colorectal Cancer Early Detection Program (PDPCCR) in the Vallès Occidental region. The trial is coordinated by the Cancer Screening Unit of the Consorci Corporació Sanitària Parc Taulí.
Operational Flow and Randomization: The study follows a sequential recruitment process. At Week 0, the entire target population receives a standard invitation letter according to the program's usual standard of care. For individuals who have not participated by Week 5, a computer-generated randomization sequence (Microsoft Excel) is applied weekly to assign them to either the intervention or control group. This weekly approach ensures the intervention is timely and integrated into the program's existing administrative workflow.
Intervention Logistics: The Intervention Group receives a one-way SMS reminder sent via the 'Alhora' platform, the secure institutional messaging system used by the screening program. The content of the SMS was previously optimized and validated through a qualitative pilot study involving semi-structured interviews to ensure high readability and cultural acceptability among the target population. Non-participants in both groups receive the standard postal reminder letter at Week 6.
Statistical Analysis Plan: The analysis will be conducted on both an intent-to-treat (ITT) and per-protocol basis. Descriptive statistics will report frequencies and medians with interquartile ranges (25th-75th percentiles). Bivariate analysis will utilize Chi-square tests for participation rates and the Mann-Whitney U test for response time differences. To estimate the effect size, Relative Risks (RR) with 95% confidence intervals will be calculated. Furthermore, a multivariate binary logistic regression will be performed using Jamovi software to adjust for potential confounders such as sex, age, geographic area, and history of previous participation

Exclusion Criteria:
- Personal history of colorectal cancer.
- Inflammatory bowel disease (IBD)
- Colorectal polyps requiring specific clinical follow-up.
- Hereditary polyposis syndromes.
- High-risk family history of colorectal cancer: a first-degree relative diagnosed before age 50, or two or more first-degree relatives at any age.

介入・治療 |
|---|---|
|
アクティブコンパレータ：Control Group: Standard Care
Participants in this group follow the screening program's standard operating procedure.
This consists of an initial invitation letter sent at week 0 and, in the event of non-participation, a postal reminder letter sent at week 6.
|
Control intervention based on the colorectal cancer screening program's usual standard of care. Components and Timing:
Duration: Participation follow-up for both components concludes 3 months after the initial invitation. This study arm receives no digital or telephone-based stimuli during the study period. |
|
実験的：Intervention Group: SMS + Standard Care
Participants receive the initial invitation letter at week 0. If they have not participated by week 5, an SMS text message reminder is sent.
If they remain non-participants following the SMS, they receive the standard postal reminder letter at week 6.
|
Control intervention based on the colorectal cancer screening program's usual standard of care. Components and Timing:
Duration: Participation follow-up for both components concludes 3 months after the initial invitation. This study arm receives no digital or telephone-based stimuli during the study period.
Behavioral intervention consisting of a one-way short message service (SMS) text message sent to the mobile phones of participants who have not completed the fecal immunochemical test (FIT) following the initial invitation.
A single SMS reminder is sent exactly 5 weeks after the issuance of the standard invitation letter, one week prior to the scheduled postal reminder.
Delivery is centrally managed through the secure 'Alhora' messaging platform.
The message format is validated through a qualitative pilot study to ensure readability and acceptability by the target population (aged 50-69 years).
