RESUMO
BACKGROUND: Colorectal cancer (CRC) incidence and mortality rates are increasing in Egypt. Because no national screening guidelines exist, developing an effective evidence-based screening intervention could lower rates by early detection of pre-cancerous and cancerous lesions and polyps. This paper describes the development of a CRC screening intervention in Alexandria, Egypt using Intervention Mapping (IM). MATERIALS AND METHODS: Between September 2019 and March 2020, the successive steps of the IM process were completed. Beginning with the needs assessment, we conducted a literature review, held focus groups with residents of Alexandria, and conducted interviews with local gastroenterologists and oncologists. Program objectives and target audience were determined before designing the program components and implementation plan. Using the PRECEDE-PROCEED theoretical model, predisposing, reinforcing, and enabling screening barriers were assessed. Finally, we developed a Standard Operating Procedures manual detailing aspects of the intervention and evaluation to serve as a model for an expanded screening program. RESULTS: The needs assessment, e.g., literature review, seven focus groups (N=61 participants) and interviews (N=17 participants), indicated that barriers among residents included CRC knowledge deficits, fear/anxiety regarding testing, high cost, and lack of accessibility. Physicians believed CRC testing should only be performed for high risk individuals. Findings from each step of the process informed successive steps. Our final intervention consisted of training components for medical students (Health Champions) who would deliver the intervention to patients in primary care waiting rooms, providing short descriptions of CRC risks and screening, educational brochures, and distributing vouchers for no-cost guaiac fecal occult blood test kits. Health Champions would then follow up with the patients, providing results and referrals for no-cost colonoscopy testing for those with abnormal results. CONCLUSION: Utilizing the IM steps successfully led to development of a theory-based CRC screening intervention for Egypt. Next steps include the implementation of a feasibility pilot intervention.

BACKGROUND: In Egypt more than one-third of colorectal cancer (CRC) cases occur in individuals aged 40 years and younger, and are diagnosed at advanced stages; currently, CRC screening is not done as a routine part of preventive care. To lay the foundation for the development of a CRC multilevel screening program in Egypt, this qualitative study aimed to explore the perspectives of Egyptian physicians. MATERIALS AND METHODS: The PRECEDE-PROCEED model, which focuses on predisposing (intrapersonal), reinforcing (interpersonal), and enabling (structural) factors inherent in health behaviors, served as our theoretical framework. Primary health care physicians, oncologists, and gastroenterologists practicing in Alexandria, Egypt, participated in 1 one-hour semistructured interview. Interviews were audio recorded, transcribed, translated into English, and analyzed by thematic analysis. RESULTS: Seventeen physicians participated (n = 8 specialists and n = 9 primary care physicians). Barriers to CRC screening included socioeconomic status, a lack of emphasis on prevention, fear, and cost (predisposing); a belief that only high risk patients should be screened and a lack of confidence in providers to perform and interpret screening tests appropriately (reinforcing); and cost, lack of availability of the tests, and inadequate training for laboratory technicians and providers (enabling). Potential facilitators included implementing a media campaign emphasizing early detection, curability and prevention (predisposing); educating physicians and eliciting physician engagement (reinforcing); and decreasing costs, making screening tests widely available, and providing well-trained providers (enabling). CONCLUSION: A CRC screening program is needed in Egypt, and to be successful it would likely need to address barriers at multiple levels. IMPLICATIONS FOR PRACTICE: In Egypt, colorectal screening is not a routine part of preventive care, and colorectal cancer is often diagnosed at an advanced stage in individuals aged 40 years or younger. Screening can prevent and detect colorectal cancer in its early stages, but before designing any screening program, understanding the context is important as cultural beliefs may impact the acceptability of screening methods. By exploring the perspectives of Egyptian physicians, this study found important insights into how screening program components should be considered in the Egyptian culture and lays the foundation for the development of a multilevel colorectal screening program in Egypt.
