中国医疗设备 2016年第5期31卷 1-4,11页

作者： ZHOU Qiang deng wen-yan CAI Kui Department of Medical Engineering Beijing Hospital Beijing 100005 China Department of Medical Equipment Beijing Hospital Beijing 100005 China Logistic & Medical Device Centre Beijing Chaoyang Hospital Beijing100020 China

With the development of technology, medical equipment plays a more important role in the modern hospital. Medical equipment provides images, physiological results or other schematics of the patients to help doctors deal with the routines. It is also the major tool to the lab assistant in the clinical teaching and studies. It becomes one of a symbol of the technological level in modern hospital. The director of the hospital should establish an effi cacious management pattern to manage the medical equipment, so that it will be operated in good condition to insure the safety of the patients. Since the maintenance is an important part of medical equipment management, it is significant that the hospital should establish a system to fit for itself. The study reviews the issues in hospital medical equipment maintenance management, the development of the maintenance management model and the characteristics, as well as the status at home and abroad. The research has been fi nished by using literature research method, questionnaire survey method and data analysis method. Then we analyze the current status of hospital medical equipment maintenance management model to fi nd the problems. Based on the authentic and effective data from the survey, we can deduce the overview about the maintenance model in Beijing. The paper discusses the advantages and the disadvantages between the different model, and it makes suggestions on the follow aspects, such as system management, quality management, personnel management, cost management, information management perspective.

目前我国已全面开展长期护理保险制度试点。通过对第一批四个试点城市的长期护理保险筹资方案进行梳理,比较分析各城市保险的筹资性质、筹资来源、筹资水平、筹资公平性,发现长期护理保险筹资来源较单一、缺乏激励措施、筹资总体水平不高、筹资公平性有待改善等问题。为完善长期护理保险筹资方案制度设计,本文提出需要特别注意的几个问题:完善筹资来源,应逐步形成合理稳定的筹资来源,拓宽筹资渠道,提高筹资水平;改善筹资公平性,从完善参保制度、加强宣传等方面提高筹资公平性;理顺保险筹资管理体系。

对美国和日本长期照护保险的筹资结构、筹资机制、公平性做比较分析,借鉴经验探索我国发展长期照护保险的筹资方式。日本长期照护保险是社会保险,相较于美国的商业保险,筹资结构更稳定。日本现收现付制与美国完全积累制的筹资机制风险都较大。从覆盖范围看,日本长期照护保险更能体现公平原则。而从使用规模看,两者都不能很好地体现公平原则。我国长期照护保险的建立应适应社会经济性质,资金的筹集应以财政为主,个人为辅,采取部分积累制,注重公平性。
