A leading medical journal is launching a global campaign to separate medicine from big pharma. The BMJ [British Medical Journal] says doctors are being unduly influenced by industry-sponsored education events and industry-funded trials for major drugs. Those trials cannot be trusted, the journal's editor and a team of global healthcare leaders write in a scathing editorial. The endemic financial entanglement with industry is distorting the production and use of healthcare evidence, causing harm to individuals and waste for health systems", they write. They are calling for governments to start funding independent trials of new drugs and medical devices, rather than relying on industry-funded studies. Sponsored research is more likely to find a favourable result compared to independent research. And they want medical associations to discourage doctors from going to industry-funded education events. Assistant Professor Ray Moynihan [is a] researcher studying the link between money and medicine and is one of the leaders of The BMJ's campaign. "When we want to decide on a medicine or a surgery, a lot of the evidence we used to inform that decision is biased," he says. "It cannot be trusted. Because so much of that has been produced and funded by the manufacturers of those healthcare products." Dr Moynihan points to ... Johnson & Johnson, which sold pelvic mesh to thousands of Australian women. It knew the mesh could cause serious harm, but never properly warned women of the risks.
