The goal of this observational study is to understand the barriers and facilitators to completing colorectal cancer screening from the patient and community health center staff perspective. The main question it aims to answer is to identify system-level determinants of colorectal cancer screening in individuals aged 45 to 54. Participants will be asked to partake in one-time interviews either online or in-person and community health center staff will also be asked to take an online survey.

Measurement of acceptability and feasibility of implementation strategies
For our primary outcome, participants will be asked to rate the acceptability and feasibility of implementation strategies using a previously validated instrument, which the investigator previously used with CHC staff. This tool has demonstrated good internal consistency reliability (0.85 for acceptability and 0.89 for feasibility) and similarly good test-retest reliability (correlations: acceptability- 0.80; feasibility - 0.88) and validity in a known groups analysis. There are no cut off numbers for acceptability and feasibility as these are just means but higher scores reflect higher acceptability. However, our surveys will allow us to better understand our survey findings. Quantitative survey interviews will be collected after first and second cycle of testing. The surveys and interviews will be measured together as this is a mixed methods study.
From planning to testing and evaluation and assessment of outcomes will be a total of 12 months

This project builds on an existing partnership with Codman Square Health Center (CSHC). CSCHC is located in the Dorchester neighborhood of Boston which has among the highest mortality rates from colorectal cancer in the city. Codman Square Health Center serves a patient population that is 86% Black and 87% income at or below the federal poverty limit, thus requiring an equity-driven approach. Patients recruited will be aged 45-54 and staff will be over aged 18 who work at CSHC and that are involved in CRC screening. There will be no clinical intervention as this is an implementation study to identify system-level determinants of colorectal cancer screening.
Survey participants will involve staff members and providers (ages 18+) involved with CRC screening processes. Patients will be health center patients.
