Development and usability heuristic evaluation of an application in PDA for supporting physicians tasks at the point of care by Olarte Enciso, Nadia Elizabeth, M.E., University of Puerto Rico, Mayaguez (Puerto Rico), 2008 , 121 pages; AAT 1451346 My Interest: 1) Usability. 2) Heuristic evaluation using Nielsen's 10 Heuristics. 3) Test/validate/evaluate the application. Action: To read the Dissertation in the future. Research Goal The main goal of this project was to develop a PDA based application to support physicians' documentation tasks at the point of care in hospitals. Motivation Nowadays, software for portable devices, such as the PDA, is commonly used among physicians in hospitals. This is indicative that physicians are probably accustomed to this type of technology and that it will not be an obstacle for them to use a PDA based clinical documentation application to perform their tasks related to patient care. Development of Tool/Application The application developed supports most of the physician's documentation tasks such as viewing the patient's record, performing medical orders, and entering progress notes. This makes the application a very useful and an important tool for the physicians in the hospitals in Puerto Rico. Comments: She tested/validated the application by performing a heuristic evaluation using Nielsen's Ten Heuristic Principles. Chapter 4: Usability Aspects 4.1. Introduction 4.2.
