Clinical Trials Data Collection Using Palm Computers

我们建议为移动、低带宽和弱连接环境开发一个临床试验信息系统。该系统将使用掌上电脑收集病人床边的数据，并在现场进行访谈。双向无线网络将根据中央存储库实时验证数据，并允许临床医生立即对异常情况做出反应。第一阶段的研究包括以下任务。我们将开发用于临床数据收集的手持系统，该系统针对小型显示器进行了优化。我们将使用n层网络架构实现用于移动感知数据管理的协议。最后，我们将在临床环境中评估原型的速度、准确性、可靠性、可接受性和通用性。建议的商业应用：我们提出的系统将为患者床边的临床试验数据收集和现场的移动访谈提供经济有效的工具。此外，我们开发的数据管理库可以作为针对小型显示器进行优化的通用用户界面工具包进行销售。

We propose to develop a Clinical Trials Information System for mobile, low bandwidth, and weakly connected environments. The system will use handheld computers to collect data the patient bedside and conduct interviews in the filed. A two-way wireless network will validate data against a central repository in real time and allow clinicians to respond immediately to anomalies. The first phase of research consists of the following tasks. We will develop a handheld system for clinical data collection that is optimized for small displays. We will implement a protocol for mobile-aware data management using an N-tier network architecture. Finally, we will evaluate the prototype in a clinical setting for speed, accuracy, reliability, acceptability, and generalizability. PROPOSED COMMERCIAL APPLICATIONS: The system we are proposing will provide an economical and efficacious tool for both clinical trial data collection at the patient bedside and mobile interviewing in the filed. In addition, the data management library we develop can be marketed as a generalizing user interface toolkit that is optimized for small displays.
