Optimizing of Waiting - Time in the Anesthesia Admissions Ambulance of the Charité - University Medicine Berlin by Support of a Mobile Application - a Pilot Study

Study Overview
=================
Brief Summary
-----------------
In this study the investigators measure and optimize the patients waiting time in the preanesthetic assessment by integrating an interactive mobile device. The aim of this study is to observe whether the patients mean waiting-time is reduced by the use of a special mobile application (Anaest-App) and, as a result , raises patient-satisfaction.

Detailed Description
-----------------
3000 patients as well as medical doctors receive tablet-devices. The Software (App) installed on these devices coordinates the virtual waiting numbers assigned to each patient-tablet. The medical doctor can virtually call up the next patient in line for preanesthesiologic assessment. After the examination both medical doctors and patients complete a brief questionaire regarding educational level, usability and overall satisfaction
