A Cluster Package Intervention to Promote an Evidence-based Use of PSA-tests in General Practice

Summary

It is widely acknowledged that prostate specific antigen (PSA) testing can lead to false-positives, overdiagnosis and overtreatment of prostate cancer. The current national clinical guidelines only recommend the test to a small group of patients and does not recommend neither systematic nor opportunistic screening for prostate cancer with the test.

The aim of this cluster randomized trial is to evaluate the effectiveness of a complex intervention aimed at improving the use of evidence based practice when using prostate specific antigen tests in general practice.

The complex intervention in this study is a so called cluster package which is meeting material to a quality cluster meeting as almost every general practitioner is a member of a quality cluster. Therefore, the investigators have developed a cluster package aimed at promoting an evidence-based use of the prostate specific antigen test to general practitioners.

Interventions

BEHAVIORAL

Podcast

A pre-recorded podcast with a urologist and a GP discussing the theme to promote preparatory reflections among the GPs before the cluster meeting

BEHAVIORAL

Cluster meeting

A two-hour meeting facilitated by either the GPs cluster coordinator, another GP from the cluster or a facilitator outside the cluster chosen by the cluster itself with specific slides about PSA in general, guidelines, expert videos, data from the clinics, cases, and group discussions

BEHAVIORAL

Hand-out material 1

Hand-outs of the main take-home messages to facilitate further discussion in their respective GP offices

BEHAVIORAL

Hand-out material 2

Hand-outs to be used by GP and patients to facilitate communication about the relevance of taking a PSA-test
