one of the 100 diseases. The questions that were incorporated into the MDI were tested for validity with office and hospital patients, and were found to yield significant information about the 100 diseases. The accuracy and usefulness of each question on the MDI were tested rigorously. Only those questions that yielded valid responses and that aided in the statistical identification of patients with any of the 100 diseases were selected for inclusion in the MDI. Selection was based on the content of questions after several variations of the form of each question were tested and the form was used which reflected maximum comprehension and validity. In Table 5 on pages 16 and 17 are listed the 100 diseases for which the MDI-Health Questionnaire was composed and tested. A code designates each disease and organ system for the Medical Data Screen. The three-digit numerical code stipulating the disease is that of the International Classification of Diseases, while the MDS alphabetical code indicates the organ system diseased. The identification of diseases by the MDS method for a typical case is here shown for a 42 year old male patient with the following numbered complaints on the MDI questionnaire: 8, 30, 33, 50, 55, 80, 95, 105, 117, 122, 124, 130, 131, 134, 137, 142, 148 and 149. For this patient the following diseases were identified by the MDS method, all of which were found by the physician when he examined the patient. BIBLIOGRAPHY In Chronological Order 1.
