In-situ evaluation of a telephone triage mobile application for in-home elderly care

We present the results of an in-situ evaluation of a mobile application aimed at assisting geriatric nurses in attending emergency calls from elders. Nurses use the application for assistance in providing a recommendation to elders. One of the main aspects to evaluate was the conditions in which the application is to be used. On the one hand, nurses have to be available 24/7 to answer emergency calls regardless of location and activity. On the other hand, the activity of answering per se can be complex since nurses have to nurses must balance between operating the mobile application, answering the phone, and interrupt their current activity. For this, we used an evaluation with a great degree of ecological validity. The lessons learned during this work will be used to enhance the design and deployment of future evaluations.
