Health technology assessment and screening in Sweden.
OBJECTIVE
To describe health technology assessment (HTA) and policies concerning three screening procedures in Sweden.


METHODS
The main source of information was reports from the Swedish Council for Technology Assessment in Health Care (SBU) and other governmental reports, supplemented by the professional literature.


RESULTS
Prevention is emphasized in the healthcare services of Sweden. Specifically, screening is encouraged and supported when it is deemed beneficial. Sweden has a strong orientation toward evidence-based health care and HTA. Since its inauguration in 1987, SBU has fostered the use of HTA in making policy and clinical decisions in Sweden. Government policy in Sweden is to encourage services that are beneficial and cost-effective and discourages services that are not. Screening is no exception to this general rule. The three cases examined in this paper-mammography screening, PSA screening, and routine ultrasound screening in pregnancy-have all been formally assessed in Sweden. Assessments have been an integral part of policy making concerning these and other preventive measures. Mammography screening has been widely implemented. However, as in other countries, screening is often carried out in an opportunistic fashion, so that PSA screening, in particular, is carried out more in Sweden than can be justified by the evidence.


CONCLUSIONS
Mammography screening is promoted and is completely available to the target group. PSA screening is discouraged, but not with complete success. Ultrasound in pregnancy is widely used, not because of good evidence of impact on mortality and morbidity among newborns, but because it increases the detection rate of congenitally malformed fetuses and because of evidence of positive effects on the management and planning of deliveries, as well as because of psychological and ethical implications of the technology. HTA is an important part of health policy making in Sweden.
