STATISTICS OF ENT OUTPATIENTS ACCORDING TO THE INTERNATIONAL CLASSIFICATION OF DISEASE (ICD) IN 1975

　I．はじめに

　最近の医学の進歩や生活水準の向上とともに，耳鼻咽喉科を受診する患者の様相は大きく変化したと考えられており，また慢性副鼻腔炎，慢性中耳炎などの疾患が著明に減少していることを学童の身体検査などからも知り得る^1）。

　一方，最近国際疾病分類方法が確立され，ほとんどすべての医療統計はこれによつて処理されるようになつてきた。これは国内外を問わず，医療機関の種類に関せず，医療の現状を比較検討し得るので便利である。

　Statistics of 6174 outpatients in Osaka University, Department of Otolaryngology, were presented according to sex difference, age decade, chief complaints, involving location and ICD.

　There is no remarkable difference in sex between 3258 males and 2916 females. Comparing to the distribution of 1% population sensus in the same year, the 6th decade reveals the highest rate of consulting to the medical service, and the 4th decade is the highest groups among the all out-patients. The location of the involved organs shows a diminishing curve in order of "Oto " " Rhino" "Pharynx " " Larynx" and "Trachea".

　In their chief complaints, hearing impairment, tinnitus, vertigo are common in the otological complaints, and nasal obstruction, rhinorrhea, sneezing, and epistaxis in the nasal, and pharyn-geal pain, tonsillar problems in the pharyngeal, and foreignbody sensation, sore throat in the laryn-geal complaints. Those most frequent complaints in each location occupies 2/3 of the all patient's statements in first visit.

　According to ICD the highest incidence of the diseases is "8. Disease of Respiratory System" and then "6. Disease of the Nervous System and Sense Organs " " 16. Symptoms, Senility and Ill-Defined Conditions " " 2. Neoplasms" in the decreasing order.
