Description:Introduction:
Many in the U.S. are 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 screening.
Methods:
Authors identified relevant publications from previous Community Guide systematic reviews of interventions to increase cancer screening (1966 through 2013) and from an update search (January 2014 to November 2021). Studies written in English and published in peer-reviewed journals were included if they assessed interventions implemented in high-income countries; reported screening for breast, cervical, or colorectal cancer; and engaged CHWs to implement part or all of the interventions. CHWs needed to come from, or have close knowledge of, the intervention community.
Results:
The review included 76 studies. Interventions engaging CHWs increased screening use for breast (median increase of 11.5 percentage points [pct pts]; interquartile interval [IQI] 5.5 to 23.5), cervical (median increase of 12.8 pct pts; IQI 6.4 to 21.0), and colorectal cancers (median increase of 10.5 pct pts; IQI 4.5 to 17.5). Interventions were effective whether CHWs worked alone or as part of a team. Interventions increased cancer screening independent of race or ethnicity, income, or insurance status.
Discussion:
Interventions engaging CHWs are recommended by the Community Preventive Services Task Force to increase cancer screening. These interventions are typically implemented in communities where people are underserved to improve health and can enhance health equity. Further training and financial support for CHWs should be considered to increase cancer screening uptake.
