ObjectiveTo analyze disease constitution and cost analysis of inpatients in the department of gynaecology of the Chengdu Women's and Children's Central Hospital in 2013, so as to get known of the patients' demands in diagnosis and treatment, and to provide evidence for further studies. MethodsWe collected information of 5 663 cases through medical records in 2013, standardized disease names according to the WHO international classification of diseases (ICD-10), and classified the kinds of diseases according to the first diagnosis of discharge records. Then we adopted the Excel software for data sorting and statistical analysis. Resultsa) Most of the inpatients were women at childbearing age. The diseases pectrum included 13 categories, with the top 3 systematic diseases including diseases during pregnancy/childbirth and puerperium (50.19%); diseases of the genitourinary system (29.31%), and neoplasms (15.54%). b) According to the ICD-10, the top 5 single diseases during pregnancy/childbirth and puerperium were ectopic pregnancy, abortion, missed abortion, threatened abortion, and hyperemesis during pregnancy; the top 5 single diseases of the genitourinary system were endometrial polyps, ovarian endometriosis cyst, uterine adenomyosis, female secondary infertility, and uterus adhesion; the top 5 single diseases of neoplasms were uterine fibroid, ovarian benign tumour, ovarian teratoma, cervical malignant tumour, and cervical carcinoma in situ. c) The average hospital stay in this department in 2013 were 6.31 days, and the average cost per capita were 6 051.10 yuan, with the top 3 kinds of costs including drugs (28.82%), operation (26.32%), and examination (20.09%). ConclusionMost of the inpatients are women at childbearing age in the department of gynaecology of the Chengdu Women's and Children's Central Hospital in 2013. Ectopic pregnancy, abortion and leiomyoma etc., are commonly-seen in this department. The average hospital stay of the inpatients is relatively short. Drugs and surgeries are main costs during hospitalization. Based on commonly-seen gynaecological disease burden, this hospital should urgently need to reinforce the construction of the specialized subjects, look for their own advantages, increase or adjust manpower, material resources and financial investment according to targets, so as to improve the quality and efficiency of medical service.
