背景：在过去的十年中，手持计算机在医学中的使用有所增加，现在它们被用于各种临床环境。有一个基本假设，即电子数据捕获比纸质数据方法更准确，但很少经过测试。本报告记录了一项研究，比较手持式计算机数据采集与更传统的纸质方法的准确性。方法：参与随机对照试验的临床护士在手持式计算机上收集患者信息，同时收集纸质数据表。两组数据均输入 Access 数据库，并将手持式计算机数据与纸质数据进行比较，以找出差异。结果：手持式计算机的错误率为每 1000 个字段 67.5 个错误，而纸质双重数据输入的可接受错误率为每 10,000 个字段 10 个错误。包含默认值的字段中的错误率最高。结论：虽然很受员工欢迎，但手持计算机却出现了令人无法接受的高错误率。如果要使用手持计算机进行临床数据收集，则需要培训和持续监控。
Background: The use of handheld computers in medicine has increased in the last decade, they are now used in a variety of clinical settings. There is an underlying assumption that electronic data capture is more accurate that paper-based data methods have been rarely tested. This report documents a study to compare the accuracy of hand held computer data capture versus more traditional paper-based methods.Methods: Clinical nurses involved in a randomised controlled trial collected patient information on a hand held computer in parallel with a paper-based data form. Both sets of data were entered into an access database and the hand held computer data compared to the paper-based data for discrepancies.Results: Error rates from the handheld computers were 67.5 error per 1000 fields, compared to the accepted error rate of 10 per 10,000 field for paper-based double data entry. Error rates were highest in field containing a default value.Conclusion: While popular with staff, unacceptable high error rates occurred with hand held computers. Training and ongoing monitoring are needed if hand held computers are to be used for clinical data collection.
