Dr. Prasad's major conclusion concerns the 363 articles that test current medical practice -- things doctors are doing today. His group determined that 146 (40.2%) found these practices to be ineffective, or medical reversals. Another 138 (38%) reaffirmed the value of current practice, and 79 (21.8%) were inconclusive -- unable to render a firm verdict regarding the practice.
Dr. Prasad comments, "A large proportion of current medical practice, 40%, was found to offer no benefits in our survey of 10 years of the New England Journal of Medicine. These 146 practices are medical reversals. They weren't just practices that once worked, and have now been improved upon; rather, they never worked. They were instituted in error, never helped patients, and have eroded trust in medicine."
Dr. Prasad adds, "Health care costs now threaten the entire economy. Our investigation suggests that much of what we are doing today simply doesn't help patients. Eliminating medical reversal may help address the most pressing problem in health care today."
Key examples of medical reversal include the following:
Stenting for stable coronary artery disease was a multibillion dollar a year industry when it was found to be no better than medical management for most patients with stable coronary artery disease. Hormone therapy for postmenopausal women intended to improve cardiovascular outcomes was found to be worse than no intervention. The routine use of the pulmonary artery catheter in patients in shock was found to be inferior to less invasive management strategies.
Other instances pertain to the use of the drug aprotinin in cardiac surgery, use of a primary rhythm control strategy for patients with atrial fibrillation, use of cyclooxygenase 2 inhibitors, early myringotomy procedures, and application of recommended glycemic targets for patie
