目的 通过对我国中医医院住院费用的主要影响因素进行分析 ,合理有效地控制医疗费用。方法 利用具有全国代表性的病案数据库 ,按照ICD 10编码 ,在全国中医监测网络的住院病案数据库中提取历年积累的前 5 0位住院病种 ,使用多层BP神经网络寻找住院费用的主要影响因素 ,并进一步分病种、医院级别进行分析。结果 当将各病种混合进行分析时 ,对住院费用 /天数影响最大的变量是医院代码和疾病种类 ,中医特有变量对费用的影响很小。分医院级别、分病种分析时的结果也完全一致。结论 在我国目前的状况下 ,医院间的差异对住院费用的影响要远大于其他各种因素 ,甚至也高于病种间的差异。因此 ,在进行医疗费用控制研究时一定要注意数据来源的广泛性和覆盖性。
Objective To analyze the main influencing factors of hospitalization costs of Chinese medicine hospitals in China and control the medical expenses reasonably and effectively. Methods Using the national representative medical record database, according to the ICD 10 coding, the top 50 inpatients accumulated over the years were extracted from the database of inpatient medical records of the national TCM monitoring network, and the main influencing factors of hospitalization costs were calculated using multi-layer BP neural network. , and further analysis of the disease, hospital level. Results When the various diseases were mixed and analyzed, the variables that had the greatest impact on hospitalization costs/day were the hospital codes and the types of diseases. The unique variables of TCM had little impact on the costs. The results at the time of analysis at the hospital level and sub-division were also identical. Conclusion Under the current situation in China, the impact of hospital-to-hospital differences on hospitalization costs is much greater than other factors, and even higher than the difference between disease types. Therefore, we must pay attention to the breadth and coverage of data sources when conducting medical cost control research.
