A medical second opinion is a practice that nails down or rules out a diagnosis of a given condition. As the American medical system pushes millions of patients per year through medical groups, errors in diagnosis are adding up. In a recent study, CBS News reported that at least 12 million Americans - as many as 1 in 20 adult patients - are misdiagnosed each year.
Previous studies have focused on misdiagnoses in the hospital setting, but the BMJ quality and safety study suggests that many are misdiagnosed at the primary care level. More seriously, researchers are saying that 50% of these patients are being placed in harm’s way through misdiagnosis or failure to diagnose. Lastly, 20% of patients with severe conditions are misdiagnosed on the first pass.
