Abstract

Objective: We assessed patient needs and resources for colorectal cancer (CRC) and breast cancer screening at nine safety-net health systems that participated in the Community Health Initiatives CHANGE Grant program run by the American Cancer Society. Methods: Fifty-two key informant interviews were conducted by ACS staff during routine site visits to each of the nine safety-net systems in the summer of 2013. Questions were asked about intervention implementation, including successes, challenges, and lessons learned. A team of researchers from ACS and the Emory Preventive Research Center (EPRC) used constructs from the Consolidated Framework for Implementation Research (CFIR) to code transcripts and examine emerging themes using each primary care setting as a case. Segments on patient needs and resources were further analyzed using a constant comparative approach. Results: The needs and resources of patients varied by system and by type of cancer screening. Common patient barriers to screening included cost of services, lack of knowledge, fears of testing and diagnosis, transportation, language differences, and low literacy levels. To address these barriers, health systems made changes to informational materials, provided referrals and partnered with organizations providing free or low-cost services, or employed patient navigators or community health workers to help patients understand and navigate the health system. Conclusions: Patient barriers to accessing and receiving preventive care services arise at all levels of health care delivery, including patient, provider, organizational, and policy levels. CFIR constructs are useful for capturing this information, but changes to construct definitions could improve the data analysis process. By addressing patient barriers, safety-net health systems can play a critical role in improving access to cancer screening for underserved populations, thereby helping to reduce the burden of disease on underserved populations and potentially lowering cancer mortality rates.
