Informed decision making before prostate-specific antigen screening: Initial results using the American Cancer...

The American Cancer Society (ACS) recommends men have the opportunity to make an informed decision about screening for prostate cancer (PCa). The ACS developed a unique decision aid (ACS-DA) for this purpose. However, to date, studies evaluating the efficacy of the ACS-DA are lacking. The authors evaluated the ACS-DA among a cohort of medically underserved men (MUM).

A multiethnic cohort of MUM (n = 285) was prospectively included between June 2010 and December 2014. The ACS-DA was presented in a group format. Levels of knowledge on PCa were evaluated before and after the presentation. Participants' decisional conflict and thoughts about the presentation also were evaluated. Logistic regression analyses were performed to determine factors associated with having an adequate level of knowledge.

Before receiving the ACS-DA, 33.1% of participants had adequate knowledge on PCa, and this increased to 77% after the DA (P < .0001). On multivariate analysis, higher education level (odds ratio, 11.19; P = .001) and history of another cancer (odds ratio, 7.45; P = .03) were associated with having adequate knowledge after receiving the DA. Levels of decisional conflict were low and were correlated with levels of knowledge after receiving the DA. The majority of men also rated the presentation as favorable and would recommend the ACS-DA to others.

Use of the ACS-DA was feasible among MUM and led to increased PCa knowledge. This also correlated with low levels of decisional conflict. The ACS-DA presented to groups of men may serve as a feasible tool for informed decision making in a MUM population. Cancer 2017;123:583-591. © 2016 American Cancer Society.
