In pursuit of equity: partnering to improve breast and prostate cancer outcomes among African Americans.

PURPOSE: Community-based participatory research (CBPR) is a collaborative partnership approach that leverages the strengths of academic-community groups to address local problems. CBPR emphasizes equity (e.g., co-learning, power-sharing, participatory decision-making) among groups to achieve goals and promote sustainability. This study examines group dynamics, and their influence on achieving shared goals, within a CBPR-guided partnership established to improve breast and prostate cancer outcomes among underserved African American communities in St. Louis, Missouri. METHODS: We conducted in-person, semi-structured interviews with key academic and community informants and surveyed via email community collaborators involved in outreach activities. Interviews were audiotaped, transcribed, and independently coded by two authors using an iterative, open-coding process to identify major themes. Surveys were summarized using similar coding criteria for open-ended responses and descriptive statistics for discrete responses. Using a grounded theory approach, we summarized and compared themes from each data source to identify similarities and differences and triangulated results to generate overarching thematic findings. RESULTS: Participants described benefits from the partnership (funding; clinical, public health and evaluation expertise; training and networking opportunities) and found beneficial ways to leverage the partners' strengths in collaborating Participants expressed long-term commitment to sustaining the partnership and building capacity to address cancer disparities, but faced challenges related to power-sharing and participatory decision-making. CONCLUSIONS: Using CBPR to address cancer disparities is an effective approach to capacity-building and achieving shared goals. By evaluating the structures and processes within CBPR collaborations through the lens of equity, partners may identify and address challenges that threaten long-term partnership sustainability.

Patient navigation to increase colorectal cancer screening among Latino Medicare enrollees: a randomized controlled trial.

PURPOSE: Latino Medicare enrollees report suboptimal rates of colorectal cancer screening (CRCS) despite Medicare policies designed to improve CRCS access for older persons. Patient navigation (PN) may address many underlying barriers to CRCS, yet little is known about the effectiveness of PN to increase CRCS adherence among Latino Medicare enrollees. METHODS: Using a randomized controlled trial study design, we evaluated tailored PN delivered outside of primary care settings as an intervention to increase CRCS adherence in this population. Intervention participants (n = 135) received tailored PN services which included education, counseling, and logistical support administered in their language of choice. Comparison participants (n = 168) received mailed cancer education materials. We compared CRCS rates between interventions and used multivariable logistic regression to assess the odds of CRCS adherence for PN versus comparison groups after adjusting for covariates of interest. RESULTS: More navigated than non-navigated participants became CRCS adherent during the study period (43.7 vs. 32.1%, p = 0.04). The odds of CRCS adherence were significantly higher for PN relative to comparison participants before and after adjusting for covariates (unadjusted OR 1.64, p = 0.04; adjusted OR 1.82, p = 0.02). Higher CRCS adherence rates were observed primarily in the uptake of endoscopic screening methods. CONCLUSION: This study demonstrates that PN delivered outside of the primary care environment is modestly effective in increasing CRCS adherence among Latino Medicare enrollees. This intervention strategy should be further evaluated as a complement to primary care-based PN and other care coordination strategies to increase adherence with CRCS and other evidence-based screenings among older Latinos.
