Facilitating Shared Decisionmaking About Prostate Cancer Screening

Background:

Due to the disputed efficacy of prostate cancer (CaP) screening and treatment, most
authorities recommend that providers inform and involve patients in CaP screening decisions.

Objectives:

This study evaluated two interventions designed to facilitate this process.

Methods:

1152 male veterans age 50+ with no CaP and primary care appointments at four VA medical
facilities in VISN 23 were randomly assigned to one of three groups: mailed pamphlet
intervention, mailed video intervention, or usual care (control). Intervention materials
were mailed two weeks prior to a target primary care appointment and patient telephone
surveys were conducted one week (T1) and one year (T2) after the target appointment.
Outcomes included: a 10- item validated knowledge index; responses to questions on CaP
natural history, treatment efficacy, PSA accuracy, and expert disagreement about the PSA;
whether screening was discussed with provider; scores on decision information seeking,
participation and satisfaction scales; screening and treatment preferences; and PSA testing
rates.
