ABSTRACT
According to the World Health Organization (WHO), mortality by age, sex, and cause of death is the foundation of public health both globally and domestically. Comparable mortality statistics over time and investigations of mortality were used to develop the International Statistical Classification of Diseases and Related Health Problems (ICD). In the ICD, the WHO states that morbidity statistics are also an essential foundation of public health, but they are much less widely applied. The 10th revision of the ICD (ICD-10) is now in use, but further revisions must be made in the development of the 11th revision (ICD-11) to capture advances in health science and medical practice, to make better use of the digital revolution, and to evaluate traditional medicine (TM). Revision of ICD-10 began in 2007, and an ICD-11 version for preparing implementation was released on July 18, 2018. ICD-11 features a new TM chapter on Japanese traditional medicine, known as Kampo medicine, traditional Chinese medicine, and Korean medicine. ICD-11 will be approved at the next World Health Assembly in May 2019 and will come into effect. This means that the WHO does not currently recognize the effects of TM, but that we as well as the WHO will have hard time to prepare and study the effects of TM on morbidity statistics. It is very important to the study of Kampo medicine that we will be able to properly evaluate the terms and classifications contained in ICD-11.
ABSTRACT
Aim of the present study was to statistically evaluate the examination rule with use of a questionnaire obtained from physicians regarding treatment for chillness of the limbs, and to prove the clinical usefulness of the database. The database showed that tokishigyakukagoshuyushokyoto was the most frequently used to treat chillness of the limbs, and subsequently keishikajutsubuto, hachimijiogan, and tokishakuyakusan were ranked as drugs with wide use. When physicians determined a kampo formulation suitable for each patient, they used findings specific for the kampo formulation, but not uniform findings obtained from the four traditional examination methods (i.e., inspection, listening and smelling, interviewing, palpitation). There was a statistical difference in the selection mode of drugs among physicians. In a simulation obtained from a questionnaire, there was a positive association between time (time X) to the start of becoming physically warm in the limbs, and time (time Y) to remission (<i>R</i><sup>2 </sup>= 0.971, <i>P </i>= 0.014). The formula (Y = 4.379 X−0.519), which could predict time Y on the basis of information on time X, was able to accurately monitor the clinical courses of 7 responders to treatment for chillness of the limbs. Taken together, these results strongly suggest that the database constructed in the present study may be useful for evaluation of traditional Kampo medicine, and might allow us to perform more fittingly personalized Kampo medicine in the near future.
