Organizations are beginning to recognize that health care providers are highly mobile and optimal care requires provid- ing access to a large and dynamic body of information wher- ever the provider and patient are. Remote display protocols (RDP) are one way that organizations are using to deliver healthcare applications to mobile users. While many organi- zations have begun to use RDPs to deliver real-time access to health care information to clinicians, little formal work has been done to evaluate the performance or the effectiveness of thin-client computing with health care applications. This study examines the performance of wireless thin-client tablets with two web-based clinical applications, a text-centric, graphics-poor EMR and a graphic-rich image analysis pro- gram. The study compares the performance of two popular RDP implementations, Citrix and Microsoft Remote Desktop, with the performance of a traditional web browser in a wire- less environment. For both applications, the RDPs demon- strated both higher speed and reduced bandwidth require- ments than the web browser.
