Importance of clinical epidemiology research in studies on respiratory diseases

Evidence-based medicine (EBM) has generated great interest since the 1990s and many physicians worldwide have based their clinical practice on this idea. Its underlying concepts include a diverse array of findings from clinical epidemiological research.In western countries, many clinical databases of clinical epidemiology are in circulation. Clinical epidemiological research using these data in western countries constitutes the majority worldwide. However, because race, lifestyle, culture, etc., differ among western countries and Japan, it is difficult to apply the results of clinical epidemiological research obtained in Japan to western countries. Unfortunately, there is no large-scale database for respiratory diseases prevalent in Japan. Many specialists agree with the opinion that it is necessary to collect medical information specific to the Japanese population and analyze the clinical data.KiHAC (Kinki Hokuriku Airway Disease Conference) was established in September 2001 with the aim of generating evidence through clinical epidemiological research for airway diseases by targeting physicians practicing respiratory medicine, pediatrics, and otorhinolaryngology, primarily in the Kinki and Hokuriku regions located in the central to western parts of Japan. As a part of the KiHAC, clinical research societies will attempt to cooperate with each other to make joint research possible and to share and utilize information, in addition to further promoting clinical research in the field of respiratory medicine.
