成本效用分析文献中效用值的来源分析

摘要

The source of the utility value was analyzed by using the retrieve relevant search terms of“health utility”,“cost effectiveness”,“quality-adjusted life years”in the Chinese periodical database of full text(CNKI), the medical database of all places and PubMed. The results showed that source utility value from 68 documents were valid in 143 qualified literatures. Using the results of the measurement of non-utility scale was the most common cause of invalid source utility value. Utility value errors and irregularities cited were another reasons. A small amount of literature didn't use the utility value. So, quality and quantity of cost-utility analysis of literature were to be in need of enhancement.%使用“健康效用”、“成本效用”、“质量调整生命年”等检索词在中国期刊全文数据库、万方医学数据库和PubMed检索相关文献，分析其中的效用值来源情况。结果显示：143篇符合条件的文献中，只有68篇文献的效用值来源有效；效用值来源无效的最常见原因是使用了非效用量表的测量结果，其次是效用值错误和不规范引用，少量文献甚至没有交待效用值。可见，成本效用分析文献的质量和数量都亟需提高。
