American scientists from the universities of Oregon, Maryland, and Chicago conducted a study in which 396 of medical devices, practices, treatments and drugs were named as ineffective or obsolete. The results of their work doctors have shared in the medical journal .
Researchers studied about 3,000 articles in 15 years about new treatments, devices and drugs, published in three leading medical journals in the UK and USA. The authors found nearly 400 cancellations of previously announced discoveries or innovations as being based on insufficient evidence.
“We hope that our findings will encourage future medical professionals to critically evaluate practices and to demand better research before implementing a new treatment,” said epidemiologist Alison Haslam of the University of Oregon health and science (OHSU).
This files most often recognized ineffective medications – their share in the total number listed in research practices and products equal to 33%. New treatment coming in second place with 20%, the proportion of vitamins and supplements with 13%. Among the areas of medicine leading methods of treatment of cardiovascular diseases is 20%.
“Thoroughly testing out new treatments before they become widely accepted, it is possible to prevent unnecessary harm to patients,” explains hematologist-oncologist from the University of Oregon health and science Vinay Prasad.
Not all of the study procedures and medicines are harmful or fatal. However, they all mean a useless expenditure and waste of time. For example, in the United States in the period from 2008 to 2009, all such services and medicines cost the health care system from 1.9 to 8.5 billion dollars.
