leveraging an implementation science framework to adapt and scale a patient navigator intervention to improve mammography screening outreach in a new community

Helping her live (hhl) is a community health worker-led outreach model that navigates women from vulnerable communities to mammography screening and diagnostic follow-up. the objective of this study was to evaluate hhl implementation on the southwest side of chicago. hhl has been implemented on the west side of chicago since 2008, where it has increased mammogram completion and diagnostic follow-up rates among black and hispanic women from resource poor communities. in 2014, hhl was translated to the southwest side of chicago; implementation success was evaluated by comparing outreach, navigation request, and mammogram completion metrics with the west side. during 2014– 2015, outreach was less extensive in the southwest setting (sw) compared to the benchmark west setting (w); however, the proportion of women who completed mammograms in sw was 50%, which compared favorably to the proportion observed in the benchmark setting w (42%). the distribution of insurance status and the racial and ethnic makeup of individuals met on outreach in the w and sw were significantly different (p < 0.0005). this successful expansion of hhl in terms of both geographic and demographic reach justifies further studies leveraging these results and tailoring hhl to additional underserved communities.
