我国许多医院病案库存严重超负荷问题已成为广大医院管理者的一大难题急待解决。本文将如何科学地应用缩微技术管理病案、如何在提高缩微存贮价值的前提下降低资金投入进行探讨。采用前瞻性调查方法对全国１５个省、市、自治区１０２家县区级以上医院进行了调查。结果表明，采用选择性病案缩微比原常规缩微平均节省资金３９．０％。而医院所属部门不同、病案年代不同、各专科医院性质不同和病种筛选不同而节省经费情况不同。但经统计学处理，总体Ｘ２＝７７０５．２５，Ｐ均＜０．００１，经费节省情况有高度显著性差异。同时，选择性缩微后，提高了资料的存储价值、利用价值、检索速度和阅读效率，节省空间更为显著。亦可用于其他资料管理中。
The serious overloading problem of medical records in many hospitals in our country has become a major problem for hospital administrators urgently to be solved. This article will be how to scientifically apply the micro-technology to manage the medical records and how to reduce the capital investment under the premise of improving the micro-storage value. A prospective survey was conducted on 102 hospitals at the district level or above in 15 provinces, municipalities and autonomous regions in China. The results show that the use of selective case reduction than the average conventional microfilm savings of 39.0%. Different hospital departments, different medical records, hospitals of different nature and different types of screening and saving funds are different. However, after statistical analysis, the overall X2 = 7705.25, P <0.001, there is a highly significant difference in funding savings. At the same time, the selective microfilm improves the storage value, utilization value, retrieval speed and reading efficiency of the data, which saves space more significantly. Can also be used for other data management.
