Abstract C104: A community guide systematic review of interventions engaging community health workers to increase appropriate breast, cervical, and colorectal cancer screening: Findings in underserved populations

Abstract

Abstract Background: Underserved adults in the United States are disproportionately not up-to-date with cancer screening. This systematic review examined the effectiveness of interventions engaging community health workers (CHWs) to increase breast, cervical and colorectal cancer (CRC) screening, especially among underserved populations. Methods: Potentially relevant publications were identified through a literature search from 1960 to July 2017. Included studies reported recent or repeat breast, cervical, or colorectal cancer screening. CHWs were recruited from or had close knowledge of the intervention community, received training to become a CHW, and implemented part or all of the intervention. Stratified analyses were conducted to examine intervention effectiveness among underserved populations. Results: Sixty-six studies with seventy study arms were included. Overall, screening rates increased for all three cancer types. Majority of the included studies examined interventions implemented among underserved populations. These interventions were effective for study populations that were 100% minority or majority minority (median increase of 12.8pct pts across cancer types, 51 study arms), majority low income (median increase of 12.7pct pts across cancer types, 30 study arms), majority uninsured (median increase of 15.0pct pts across cancer types, 12 study arms), or lived in rural areas (median increase of 10.2pct pts across cancer types, 12 study arms). Conclusions: Interventions engaging CHWs were effective in increasing breast, cervical, and CRC screening for underserved populations.
