A new Danish study showed that routine examination does not affect the mortality rate of patients from heart disease or cancer.
These results are applicable to doctor visits, visiting on a regular basis are not complaining about the health of patients who are not exposed to any risk factors for conducting the type-checking and giving advice on healthy living.
The purpose of these studies is to identify the disease symptoms in the early stages and thus reduce the risk of death.
However, as shown by a new revision of 14 previous studies, in which participated 183 000 patients, there is no evidence of any use of such surveys. On the contrary, the research team found that routine examinations of healthy people may lead to the use of potentially dangerous, aggressive testing methods, leading to false diagnoses and unnecessary treatment.
"We found no evidence of benefit from systematic, regular surveys of health in the regular preventive health care, despite the fact that we have analyzed the many trials of high quality, which was attended by nearly 200,000 people," - says the lead author of the study, Lasse Krogsboll , applicant for the PhD degree from the Nordic Cochrane Centre in Copenhagen.
He added: "You can not take for granted that more diagnoses and more medication - it is always for the better. Our results did not reveal the optimal preventive strategy, but they definitely do not support the idea of regular, systematic surveys of health, in addition to routine clinical practice."
Krogsboll and his colleagues published the findings in the British Medical Journal (BMJ) on November 20.
As it turned out, led to a jump in checking the number of diagnoses, as well as an increase in the number of patients, but such a routine doctor’s visit did not lead to a reduction in overall mortality or a decrease in the risk of death from cardiovascular disease or cancer.
In an accompanying article, the editor of the journal BMJ Domnall Dr. Macaulay, wrote that "the system should be based on the evidence of improvement, rather than on one’s good intentions." He rejected the idea that the testing of healthy people is a good strategy for the sole reason that "it is considered to be socially responsible approach to patient care."
