Why Best Doctors?

If you or one of your family developed a significant medical condition, you would want to be absolutely sure about the diagnosis you received and the treatment which was recommended. You would likely have all sorts of questions about the condition itself, the options for treatment and the risks involved. You would want to be completely certain that an adequate level of care and skill had been exercised, and that your case was not being mishandled.

The onset of significant medical conditions happens to people every day. If it happened to you, would you like a second opinion from a world-class specialist in that field who had fully studied your case? Not someone who would replace your specialist, but someone who would provide independent advice and confirmation of the diagnosis, and advice on the most appropriate treatment for your condition.

At your request as a member, Best Doctors will assign a world-leading medical expert in that field to thoroughly review your case. Regardless of where that expert was located, be it New York, London, Paris, Berlin, Toronto, Sydney or any other city in the world, Best Doctors will identify and appoint a world-leading medical specialist in that field who will review your case. You will then receive a detailed written report which confirms the diagnosis or otherwise, and which provides recommendations on the most appropriate treatment. You can then choose to share that advice with your doctor.

Medical Misdiagnosis

Medical misdiagnosis is a common occurrence. In a major study which compared clinical diagnoses with post-mortem results1, it was found that the correct diagnosis was missed in 26% of patients. The researchers concluded that: "Despite the introduction of more modern diagnostic techniques and of intensive and invasive monitoring, the number of missed major diagnoses has not essentially changed over the past 20 to 30 years."

Misdiagnosis occurs across all fields of medicine. For example, in the field of radiology a major study found error rates of up to 32% in failing to detect abnormalities2 (false negatives). Error rates ranging from 25% to 49% have been recorded in pathologists’ interpretations of biopsy specimens3, and a pathology journal4 reported a 24% error rate in laboratory tests. These and other research findings suggest that patients should be more circumspect and enquiring about medical diagnosis and testing.

Who are Best Doctors?

Best Doctors was founded in Cambridge, Massachusetts in 1989 by two physicians: Kenneth Falchuk, Emeritus Professor of Medicine at the Harvard Medical School, and Jose Halperin, Associate Professor of Medicine at the Harvard Medical School. Both founders remain on the Medical Advisory Board of Best Doctors today.

The Best Doctors network consists of more than 50,000 expert physicians worldwide, drawn from over 400 medical subspecialties. Best Doctors physicians are chosen by other doctors as the pre-eminent experts in their field, and they represent the top 5% of physicians in their respective specialties.

Best Doctors is now established in more than 70 countries throughout the world, and has more than 30 million individual members. In New Zealand, Best Doctors is based in central Auckland and has a permanent medical staff to assist in gathering medical notes, pathology and other material for reviews which are requested by individual members.
