We analyzed the regular pattern of daily medicine cost change of operation inpatients during hospitalization in every group . the results indicated that the median line of daily medicine cost had similar regular pattern in operations on the nervous system , the musculoskeletal system , the nose , mouth , and pharynx system and the female genital organs system : the top of daily medicine cost median emerged on the day of operations ; the median of daily medicine cost was low in the period after operation , and the lowest in the period before operation . the median line of daily medicine cost of operations on the digestive system and the integumentary system keeped at a high level in the period of 1 - 6 days after operations 手术病人日药费随住院时间的变化规律按icd - 9 - cm类目表的15个系统大类（解剖学分类）将住院手术病人分为15组，分析了各系统手术病人住院期间日药品费用的变化规律，结果显示：神经系统、肌肉骨骼系统、鼻口咽系统和女性生殖系统手术的日药费中位数线图具有相似的变化规律：手术病人住院期间的日药费硕士学位论文中位数的峰值位于手术当日，且手术当日的日药费变异最大；术后住院日的日药费中位数明显降低；术前住院日的日药费中位数很低；消化系统和体被系统手术在手术当日及术后1 6天内的日药费中位数维持在较高的水平。
