New mobile computing devices including personal digital assistants (PDAs) and tablet computers have emerged to facilitate data collection at the point of care. Unfortunately, little research has been reported regarding which device is optimal for a given care setting. In this study we created and compared functionally identical applications on a Palm operating system-based PDA and a Windows-based tablet computer for point-of-care documentation of clinical observations by eye care professionals when caring for patients with diabetes. Eye-care professionals compared the devices through focus group sessions and through validated usability surveys. We found that the application on the tablet computer was preferred over the PDA for documenting the complex data related to eye care. Our findings suggest that the selection of a mobile computing platform depends on the amount and complexity of the data to be entered; the tablet computer functions better for high volume, complex data entry, and the PDA, for low volume, simple data entry.
包括个人数字助理（PDA）和平板电脑在内的新型移动计算设备已经出现，以方便在护理现场进行数据收集。不幸的是，关于哪种设备在特定护理环境中是最佳选择的研究报道很少。在本研究中，我们在基于Palm操作系统的PDA和基于Windows的平板电脑上创建并比较了功能相同的应用程序，用于眼科护理专业人员在护理糖尿病患者时对临床观察进行护理现场记录。眼科护理专业人员通过焦点小组会议和经过验证的可用性调查对这些设备进行了比较。我们发现，在记录与眼科护理相关的复杂数据时，平板电脑上的应用程序比PDA更受青睐。我们的研究结果表明，移动计算平台的选择取决于要输入的数据量和复杂性；平板电脑在大量、复杂的数据输入方面功能更好，而PDA在少量、简单的数据输入方面表现更佳。
