The Centers for Medicare and Medicaid Services (CMS) has awarded cooperative agreements to 6 sites from across the country (Salt Lake City, UT, Molokai, HI, Houston, TX, Newark, NJ, Detroit, MI, and Baltimore City) to participate in a national 4-year demonstration (September 15, 2006 to September 30, 2010). One goal of the demonstration is to reduce disparities in cancer treatment among seniors from U.S. racial and ethnic minority populations. Each site will focus on a specific racial/ethnic minority group, and collaborate with CMS in project implementation. A Core questionnaire, the Cancer Screening Assessment (CSA) will be administered at baseline to all participants in the demonstration. Participant identification, randomization, and intervention implementation will be standardized across sites. Goal: The proposal developed by the Johns Hopkins Bloomberg School of Public Health in collaboration with the Baltimore City Community Health Coalition is designed to address persistent disparities in breast, cervix, colon/rectum, prostate and lung cancer treatment. Primary Objective: Conduct A CONTROL RANDOMIZED TRIAL within a randomized control demonstration project (N = 200) to compare the efficacy of 2 interventions that differ in intensity to improve continuity and outcomes of care among African Americans seniors. Among African American seniors, compared to a less intensive intervention (general information and educational materials), does the addition of facilitation services delivered by a health coordinator result in a greater improvement in adherence to recommended treatment among those diagnosed with breast, cervix, colon/rectum, prostate, or lung cancer? Study Population: We will recruit African Americans, age 65 years or older, and currently enrolled in Medicare Parts A and B. (Baltimore City's 82,202 seniors represent 13% of its population, and account for 68% of the City's cancer deaths. Among these seniors, 96% have Medicare Parts A and B, 54.5% have income levels at less than 250% of the federal poverty guideline, and 55.6% are African American.) The trial consists of individuals diagnosed with breast, cervical, colorectal, prostate, or lung cancer. Eligible participants will respond to a baseline questionnaire, the Cancer Screening Assessment (CSA). They will then be randomized to receive a less intensive or more intensive intervention. The less intensive group will receive general information about cancer and Medicare covered services and instructions to discuss the information with their primary care doctor. The more intensive group will receive the same information as the less intensive group receives, plus tailored facilitation services delivered by a nurse-supervised community health worker. The primary outcome variable for the trial will be the difference between randomized groups in adherence to treatment for breast, cervix, colon/rectum, prostate and lung cancer. A community advisory committee will guide all aspects of the study and will include important stake holders (both public and private sectors), representatives from the Baltimore City Community Health Coalition, the Baltimore City Department of Health, the Maryland Department of Health and Mental Hygiene, community leaders, consumers, health care providers (physicians, oncologists, nurse practitioners, physician assistants, nurses, social workers, pathologists) and academicians.
