In Hippocrasy, rheumatologist and epidemiologist Rachelle Buchbinder and orthopaedic surgeon Ian Harris argue that the benefits of medical treatments are often wildly overstated and the harms understated. That overtreatment and overdiagnosis are rife. And the medical system is not fit for purpose: designed to deliver health care not health. This powerful expose reveals the tests, drugs and treatments that provide little or no benefit for patients and the inherent problem of a medical system based on treating rather than preventing illness. The book also provides tips to empower patients – do I really need this treatment? What are the risks? Are there simpler, safer options? What happens if I do nothing? Plus solutions to help restructure how medicine is delivered to help doctors live up to their Hippocratic Oath.
