The most common type of diagnostic “quality control” is a patient-initiated second opinion1. In one study, 38% of patients sought a second opinion because they had doubts about the diagnosis or treatment and 19% sought a second opinion because they were dissatisfied with the level of communication2.
Studies show that second opinions typically confirm the original diagnosis or treatment regimen. In one study, between 10% to 62% of second opinions yielded a major change in the diagnosis, treatment, or prognosis3. In another study, 84% mentioned that they were satisfied with their second opinion, 77% felt health improvement, and 56% indicated that there was a difference between the diagnosis or treatment from the first and second opinion4.
If you want to enhance the accuracy of your diagnosis or recommend course of treatment, a second opinion can help.
