Personal health records are web-based applications that allow patients to directly enter their own data into secure repositories in order to generate accessible profiles of medical information.
The authors evaluated a variety of user interfaces to determine whether different types of data entry methods employed by Personal health records may have an impact on the accuracy of patient-entered medical information.
Patients with disorders requiring treatment with thyroid hormone preparations were recruited to enter data into a web-based study application. The study application presented sequences of exercises that prompted free text entry, pick list selection, or radio button selection of information related to diagnoses, prescriptions, and laboratory test results. Entered data elements were compared to information abstracted from patients' clinic notes, prescription records, and laboratory test reports.
Accuracy rates associated with the different data entry methods tested varied in relation to the complexity of requested information. Most of the data entry methods tested allowed for accurate entry of thyroid hormone preparation names, laboratory test names, and familiar diagnoses. Data entry methods that prompted guided abstraction of data elements from primary source documents were associated with more accurate entry of qualitative and quantitative information.
Different types of data entry methods employed by Personal health records may have an impact on the accuracy of patient-entered medical information. Approaches that rely on guided entry of data elements abstracted from primary source documents may promote more accurate entry of information.
个人健康记录是基于网络的应用程序，允许患者将自己的数据直接输入到安全的存储库中，以生成可访问的医疗信息档案。
作者评估了各种用户界面，以确定个人健康记录所采用的不同类型的数据输入方法是否可能对患者输入的医疗信息的准确性产生影响。
招募需要用甲状腺激素制剂治疗的疾病患者，将数据输入到一个基于网络的研究应用程序中。该研究应用程序展示了一系列练习，提示患者以自由文本输入、选择列表选择或单选按钮选择与诊断、处方和实验室检查结果相关的信息。将输入的数据元素与从患者的临床记录、处方记录和实验室检查报告中提取的信息进行比较。
与所测试的不同数据输入方法相关的准确率因所要求信息的复杂性而异。所测试的大多数数据输入方法都能准确输入甲状腺激素制剂名称、实验室检查名称和常见诊断。提示从原始资料文档中引导提取数据元素的数据输入方法与定性和定量信息的更准确输入相关。
个人健康记录所采用的不同类型的数据输入方法可能对患者输入的医疗信息的准确性产生影响。依赖于从原始资料文档中引导输入提取的数据元素的方法可能会促进信息的更准确输入。
