Utilization of Colorectal Cancer Screening among Saudi Elderly Population: A Study from the Saudi National Survey for Elderly Health.

Objective: The goal of this study was to measure colorectal cancer screening (CRCS) utilization in Saudi Arabia ’s elderly population and to assess the factors associated with CRCS. Methods: The Saudi National Survey for Elderly Health was used to examine CRCS utilization. It is a nationally representative population-based cross-sectional survey that was conducted between 2006-2007. Utilization of CRCS was defined as any colonoscopy during the last five years or fecal occult blood test (FOBT) during the twelve months before the interview. Multivariable logistic regression was used to assess patients’ demographics, co-morbidities, number of visits to primary health clinics, and hospital availability and accessibility impact on CRCS. Results: The prevalence of CRCS utilization among Saudi elderly population was 5.64%. The fecal occult blood test was done in 4.4% of subjects while scope use was performed in 0.55%. In addition, 0.69% of patients have gone through both FOBT and scope use. Having blood in stools (OR=2.80; 95%CI: 1.3-6.00), Self-drivers (OR= 2.52) private driver (OR=2.1; 95%CI: 1.15-3.7) having 4 or more visits to primary care centers 1.81 (95%CI: 1.14-2.86) were positively associated with CRCS utilization. On the other hand, being single was negatively associated with CRCS utilization. Conclusion: In this nationally representative sample CRCS prevalence was very low. According to our findings and in the context of the burden of colorectal cancer on the population, we recommend developing national evidence-based policies and programs that take in consideration easiness of transportation and the availability of primary care centers near to Saudi elderly population.
