hematology, pediatric neurology, pediatric metabolism & endocrinology, pediatric chest, pediatric nephrology, pediatric surgery, pediatric infectious diseases, pediatric allergy, immunology and rheumatology, and others [3,4,11]. In addition, the International Disease Classification Number One (ACODE ICD 10) field in the emergency file (CD) of the health insurance database was used. The diagnosis was divided into the 12 groups based on the diagnostic classification used by many domestic researchers [12-13]. If children received more than one diagnosis, a primary diagnosis was assigned in the following order: respiratory disease (croup, pneumonia, bronchitis, bronchiolitis, acute otitis media and acute laryngitis), gastrointestinal diseases (gastritis, colitis, hepatitis and pancreatitis) and infectious disease (enterovirus infection, influenza and fever). Data of distributions of variables were reported as percentages and means ± standard deviation (SD). the frequency distribution, percentage, and average are used to describe the emergency medical use of children.
