The medical literature reports that 40%-80% of chronic pain patients are misdiagnosed. Clearly, misdiagnosis leads to ordering the wrong tests, and thereby obtaining an incorrect diagnosis, or overlooking a diagnosis totally, which results in mistreatment. Many reports in the medical literature indicate the best way to get an accurate diagnosis, is to obtain a complete and thorough history. However, this is a time consuming process, and most physicians don’t spend the needed time with a patient. Therefore, a team of doctors from Johns Hopkins Hospital developed a 72 question test, with 2008 possible answers, available over the Internet. When a patient completes the questionnaire, diagnoses are returned within 5 minutes. These diagnoses have a 96% correlation with diagnoses of Johns Hopkins Hospital doctors. This is the highest level of accuracy of any expert system available. The efficacy of this approach is proven by outcome studies, which prove that this approach results in a far higher return to work rate and reduced use of medication and doctors visits, when compared to other techniques. This is similar to the techniques used by Johns Hopkins Hospital to reduce their workers compensation payments by 54%.
