Health technology assessment and implications for clinical practice: the case of prostate cancer screening

We describe an initiative to disseminate evidence from systematic reviews about the clinical effectiveness of prostate cancer screening to general practitioners and urologists in Norway. The Norwegian Centre for Health Technology Assessment invited The Norwegian Medical Association, The Norwegian Cancer Society, The Norwegian Board of Health, The Norwegian Urological Cancer Group and The Norwegian Patient Association to develop and disseminate clinical practice recommendations. The clinical effectiveness of prostate cancer screening has been assessed in nine independent systematic reviews, which are summarized in a joint INAHTA report. The conclusion was that there is no evidence from appropriately designed trials that early detection and treatment of prostate cancer can reduce mortality, morbidity or improve quality of life. The number of prostate‐specific antigen (PSA) tests analysed in Norway increased by 30% from 1996 to 1999; at the county level the increase ranged from 12 to 48%. On this background ...
