A Study to Compare a CHW-Led Versus Physician-Led Intervention for Prostate Cancer Screening Decision-Making among...

Prostate cancer is the second leading cause of cancer deaths among men in the United States and harms Black men disproportionately. Most US men are uninformed about many key facts important to make an informed decision about prostate cancer. Most experts agree that it is important for men to learn about these problems as early as possible in their lifetime.

To compare the effect of a community health worker (CHW)-led educational session with a physician-led educational session that counsels Black men about the risks and benefits of prostate-specific antigen (PSA) screening.

One hundred eighteen Black men recruited in 8 community-based settings attended a prostate cancer screening education session led by either a CHW or a physician. Participants completed surveys before and after the session to assess knowledge, decisional conflict, and perceptions about the intervention. Both arms used a decision aid that explains the benefits, risks, and controversies of PSA screening and decision coaching.

There was no significant difference in decisional conflict change by group: 24.31 physician led versus 30.64 CHW led (P=.31). The CHW-led group showed significantly greater improvement on knowledge after intervention, change (SD): 2.6 (2.81) versus 5.1 (3.19), P<.001). However, those in the physician-led group were more likely to agree that the speaker knew a lot about PSA testing (P<.001) and were more likely to trust the speaker (P<.001).

CHW-led interventions can effectively assist Black men with complex health decision-making in community-based settings. This approach may improve prostate cancer knowledge and equally minimize decisional conflict compared with a physician-led intervention.
