PROSPR Project 1: Identifying and Tracking Personalized CRC Screening Regimens for Patients in Clinical Settings

Each of the Population-based Research Optimizing Screening through Personalized Regimens (PROSPR) Center's projects is innovative and addresses the continuum of care. Project 1 addresses transitions 1 and 3, employing novel, algorithmically driven tools in clinics to determine personalized optimized screening regimens for individual patients and track whether each has received the indicated guideline-based screening. Project 2 addresses all three transitions through a novel comparative effectiveness study of benefits, risks, and costs of two outreach strategies for promoting screening completion and guideline-appropriate follow-up. Project 3 addresses transitions 2 and 3 by focusing on organizational culture, structure, and protocols, using both quantitative and qualitative methods to elucidate factors influencing completion of effective screening processes. These projects address research priorities identified through a recent National Institute of Health (NIH) State of the Science Conference, including: implementing interventions proven effective at increasing colorectal cancer (CRC) screening (Projects 1 \& 2), conducting research to assess effectiveness of tailoring programs to match characteristics and preferences of target populations (Project 1), implementing systems to ensure follow up of positive CRC screening results (Projects 1, 2 \& 3), and conducting studies to determine comparative effectiveness of CRC screening methods in usual practice (Project 2). PROSPR Center's goals are to: 1. Develop a Parkland-UT Southwestern PROSPR Center to promote coordinated, transdisciplinary research to evaluate and improve the CRC screening process in a large population-based safety-net. 2. Conduct three projects that address the continuum of care for CRC screening and address these goals: Project 1- Employ innovative methods for assessing personalized guideline-based screening in the clinic setting to evaluate guideline-based, over- and under-screening; Project 2 - Compare benefits, harm, and costs of three system-level strategies for inviting patients to screening and promoting guideline-based follow up, with particular focus on completing an effective screening process. Project 3 - Examine specific organizational factors that contribute to completion of guideline-based screening processes and examine which organizational factors modify relationships between social disadvantage and completion of guideline-based repeat screening and follow up of abnormal test results. 3. Contribute to a national PROSPR network by actively participating in network activities, including: 1. collaborating with the National Data Coordinating Center regarding approaches for measuring screening effectiveness, (b) sharing algorithmically driven tools facilitating personalized screening regimes, (c) sharing electronic medical record (EMR) capabilities with other Epic institutions, and (d) becoming a leader in cancer screening processes in safety-net systems. While the SPDU will be exclusively responsible for all required PROSPR network data collection, processing and transfer activities, our complementary Shared Research Resources Core (SRRC) will serve as the local "data coordinating center" of our PROSPR center. The SRRC will work with Projects 1-3 to identify patients for recruitment; track study accrual; and manage, process, and analyze all Project data. The SRRC will also help assure consistent data definitions and terminology for harms, benefits, and other common domains across the screening process documentation unit (SPDU) and Projects. The SRRC and SPDU will work closely together as much of the required SPDU screening process data will be used by the SRRC to identify eligible patients for Projects 1-3, and ascertain the processes and outcomes of the CRC screening process for study participants. An innovative activity of the SRRC will be to extract from Epic a novel set of electronically derived measures of social disadvantage previously developed by the Parkland Center for Innovation.27 This will empower Projects 1 and 2 to examine the influence of these factors on the in-reach and out-reach programs, as well as provide Project 3 with critical explanatory variables to understand the impact of clinic-level organizational factors on the CRC screening process.
