Effects of an assessment of needs for medical and social services on long-term mortality: a randomized controlled study.

BACKGROUND: The aim of this study was to investigate the long-term effects of one general health screening on mortality. METHOD: After stratification and randomization of a population of 450,000 inhabitants, two groups were formed, an intervention group of 3064 people and a control group of 29,122 people. From the National Cause of Death Register, data were collected as regards death and causes of deaths for 1970-1990. RESULTS: Multivariate analysis was used to correct for known confounders. We then found no differences between the groups regarding deaths from all causes, cardiovascular diseases, cancer or accidents and poisoning. CONCLUSIONS: One general health screening seems to have little, if any value in preventing fatal diseases.
