About
This study is designed to assess the effect of implementing a text messaging strategy for colorectal cancer screening among homeless persons aged 45-75 years, who are not up to date on colorectal cancer screening, in shelter clinics in NYC. This mixed-methods study uses a randomized clinical trial design and semi-structured interviews.
Full description
This study seeks to evaluate the extent to which an SMS text-based patient navigation will mitigate some of the barriers to and improve CRC screening in homeless persons. It will include processes customized to the homeless specific needs via a streamlined approach of an SMS text-based navigation in shelters clinics to explain cancer risks and screening options, provide test instructions and support, identify and resolve challenges to screening, respond to questions and concerns, make appointments for screening, support screening completion, provide post-screen counselling, and obtain test results to complete screening loop. The target population will be homeless persons aged 45-75, not up-to-date with CRC screening, recruited from shelter clinics of a community organization serving homeless persons in New York City (NYC). The specific aims of this mixed methods study are:
AIM 1: To evaluate the effect of 6-month SMS text-based patient navigation for CRC screening (INT) versus an attention control (CL) of general health promotion on the completion rates of CRC screening using a randomized trial design in shelter clinics. Hypothesis 1) among homeless persons aged 45-75 not up-to-date with CRC screening, those randomized to the INT (n=294) will have higher CRC screening rates in the magnitude of 10 percentage points, compared to those randomized to the CL (n=294) at 6 months post enrollment. Individual-level randomization will be employed in shelter clinics in NYC.
AIM 2: To evaluate perceptions, attitudes, and experiences of homeless persons (n=50) and providers and staff (n=20) on SMS text navigation for CRC screening in shelter clinics using semi-structured interviews. The results will strengthen the SMS navigation approach by revealing barriers and necessary adaptation needs.
AIM 3: To evaluate perceptions and attitudes of program staff (n=20) of agencies servicing homeless persons in NYC and on the national level on challenges and opportunities of implementing SMS text navigation for cancer care and control in the shelter system using semi-structured interviews.
