Increasing Access to Colorectal Cancer Screening Among Immigrants
Increasing Access to Colorectal Cancer Screening Among Immigrants
The goal of this randomized trial is to test the effect of a reminder telephone call in the official native language in the country where the invitee is born, in addition to the reminder letter in Norwegian on participation in the National Colorectal Cancer Screening Program in Pakistani and Somalian immigrants, compared to the reminder letter in Norwegian only.
The main question it aims to answer is:
•Does a reminder telephone call in the language of origin increase participation in colorectal cancer screening in Pakistani and Somalian immigrants in Norway?
Participants in this trial are individuals with Pakistan or Somalia as their country of birth invited to the National Colorectal Cancer Screening Program, who have not participated by mailing a faecal sample to the screening laboratory.
In the intervention group, the participants will be called in the official language in their country of origin, to inform about colorectal cancer screening, in addition to the reminder letter in Norwegian language sent to all non-participants.
Participants in the comparison group will only be sent the reminder letter in Norwegian language.
The researchers will compare differences in the participation rate in the National Colorectal Cancer Screening Program between the intervention and comparison groups.
The aim of the project is to study the effect of reminding non-participant Somalian and Pakistani immigrant groups by a telephone call in the official native language in the country of birth, in addition to the reminder letter in Norwegian, by running a randomized trial. The outcome is participation in the National Colorectal Cancer Screening Program by taking a faecal sample with a mailed test kit.
The design of the trial is a parallel two-arm intervention study, with 1:1 randomization to intervention or control.
The intervention consists of a reminder both as telephone call in the native language of the non-participant's country of birth and the standard reminder letter (sent digitally or in mail) in Norwegian from the National Colorectal Cancer Screening Program. The timepoint of the telephone call will be during a week after the reminder letter has been mailed to the non-participant. The information to be given in the reminder call will include the same information as given in the reminder letter, but it will be asked additionally whether the invitee has understood the invitation and whether he/she has any questions. A new faecal sample kit will be sent on request.
The control arm will consist of screening practice as usual, which is the standard reminder letter in Norwegian from the National Colorectal Cancer Screening Program. A new faecal sample kit will be sent on request.
Masking: There is no masking in the trial. Allocation: This is a randomized trial. Participants are assigned to intervention groups by chance, using Random Integer Generator in random.org, when being assigned to the list of persons to whom a reminder is sent to.
Participation rate in the National Colorectal Cancer Screening Program will be compared between the intervention and control arms. That is, comparison of the proportion of individuals who send a faecal sample in mail to the screening laboratory.
