System Dynamics of CRC Screening and EBI Implementation

These diagrams illustrate the key factors influencing colorectal cancer (CRC) screening and the implementation of evidence-based interventions (EBIs). They explore clinic decision-making, cost dynamics, sustainability challenges, and screening completion factors, highlighting the interconnected systems that shape screening outcomes. By understanding these relationships, clinics can optimize resources, improve adherence, and enhance long-term EBI impact.

Navigating System Dynamics in Selecting & Implementing EBIs for CRC Screening

This diagram maps the complex factors influencing clinics’ decisions in selecting, adapting, and implementing evidence-based interventions (EBIs) for colorectal cancer (CRC) screening. Using a causal loop framework, it highlights key dynamics such as clinic openness, resource availability, system complexity, and implementation capacity. By understanding these interdependencies, clinics can identify barriers, leverage strengths, and refine strategies to enhance screening effectiveness and long-term impact.

Ensuring Long-Term Sustainability of EBIs for CRC Screening

This diagram illustrates the key factors influencing the long-term sustainability of evidence-based interventions (EBIs) for colorectal cancer (CRC) screening. It highlights how clinic priorities, funding stability, leadership support, and integration into existing workflows impact EBI effectiveness over time. By embedding sustainability considerations early—such as integrating EBIs across screenings, securing stable funding, and strengthening partnerships—clinics can maintain high screening rates and minimize disruptions from shifting priorities or staff turnover.

Cost Drivers and Cost-Effectiveness of EBI Implementation

This diagram explores the financial dynamics of implementing and sustaining evidence-based interventions (EBIs) for colorectal cancer (CRC) screening, emphasizing cost-effectiveness as a key factor in long-term viability. It highlights how integrating EBIs into existing workflows, optimizing resource use, and automating EHR systems can reduce costs while improving efficiency. By maximizing economies of scale and leveraging automation to streamline processes, clinics can enhance EBI sustainability and ensure continued impact despite resource constraints.

Cost Considerations of Stool-Based Testing vs. Colonoscopies

This diagram compares the cost dynamics of stool-based CRC screening and colonoscopies over time, highlighting factors that influence per-person screening costs. Stool-based tests lower initial costs but require annual testing and follow-up colonoscopies for positive results, while colonoscopies have higher upfront costs but longer screening intervals. Patient costs, adherence rates, and the need for diagnostic follow-ups all impact the overall financial sustainability of screening programs, emphasizing the importance of resource allocation and patient navigation support to optimize screening completion.

Factors Influencing CRC Screening Completion and Follow-Up

This diagram explores key factors affecting the completion of routine colonoscopies and stool-based CRC screening, emphasizing the role of patient navigation, provider preferences, and system automation. Patient education, outreach, and partnerships between clinics and endoscopy providers enhance screening adherence, while EHR automation and mailed FIT programs improve access to stool-based testing. Balancing loops highlight challenges such as maintaining annual screening adherence and follow-up colonoscopies, underscoring the need for strategic interventions to sustain high screening rates and improve early CRC detection.
