Impact of a Prostate Specific Antigen Screening Decision Aid on Clinic Function.

ABSTRACT

INTRODUCTION: Decision aids (DAs) around prostate cancer screening can increase knowledge and shared decision making (SDM), but remain underutilized due to cost and time constraints that disrupt clinic flow. We examined the impact of a simple prostate specific antigen (PSA) screening DA distribution strategy on clinic flow as well as SDM in a diverse urban primary care clinic. METHODS: Men ages 50-75 viewed the DA while waiting for physicians. Participants and physicians completed questionnaires evaluating the SDM process. Focus groups were conducted with clinic staff and physicians to evaluate the impact on clinic operations. RESULTS: Fifty percent of men discussed PSA screening and 85% reported the DA made decision making easier. Participants reported an average of 12.9 min reading the DA. Participants reported high decision satisfaction and low decisional conflict. Physicians reported an average of 5.2 minutes discussing PSA screening. Clinic staff reported increased enthusiasm for the process after adjustments were made in response to concerns including time, and lack of both knowledge about the DA subject matter and involvement in the process. Physician-reported barriers included ambivalence about PSA screening. CONCLUSIONS: A PSA DA, requiring few resources, can be implemented with broad involvement of clinic staff and minimal disruption to clinic flow in an urban primary care clinic, and may facilitate SDM.
