Evaluating a Group-Based Program to Improve Evidence-Based Use of PSA Tests in General Practice

What this Trial Is About

Prostate cancer is the most common cancer among men in Denmark, often developing slowly without symptoms. This trial evaluates a complex intervention designed to improve how general practitioners GPs use prostate specific antigen PSA tests in line with national guidelines. The goal is to reduce overdiagnosis and overtreatment caused by unnecessary PSA testing, by promoting evidence-based practice among GPs in quality clusters. The intervention involves a cluster package including a pre-recorded podcast for GPs, a two-hour cluster meeting with educational material and group discussions, and two sets of hand-outs to support GPs in their clinics. Quality clusters are randomized to either receive this intervention over six months or act as a control group, which will be offered the intervention afterward. Participants, who are quality clusters of GPs, will be involved in cluster meetings and use the provided materials. Researchers will measure changes in PSA testing frequency among men during the six-month intervention period, as well as variations between GPs. The study includes assessments of PSA test use before and after the intervention to evaluate its impact on clinical practice.
