Evaluation of Digital, Telephonic and Conventional Consent for Anaesthesia

Study Overview
=================
Brief Summary
-----------------
In this study, the investigators aim to evaluate patient satisfaction between three methods of obtaining informed consent for anaesthesia. Patients are asked to partake in a short survey after being informed about the anaesthetic procedure either conventionally in the anesthesia department, telephonically or digitally.

Detailed Description
-----------------
Patient satisfaction plays an important role to improve the process of medical procedures as well as patient outcome. Evaluating the subjectively experienced satisfaction is challenging. The investigators will use a questionnaire and assess waiting times in the process to determine patient satisfaction between digital, telephonic and conventional obtaining of informed consent for anaesthesia. In this questionnaire study, patients are asked to partake in a survey after the process of obtaining consent for anaesthesia is completed. The questionnaire covers aspects of patient satisfaction with the process, such as subjective assessment of comprehensibility, waiting time and privacy. Patients are divided into three groups. In one group, consent is obtained conventionally, in form of a visit to our anaesthesia department. In the other two groups, consent is obtained telephonically and digitally, respectively. Patients are not randomised into these groups, but included into the study after the process of obtaining consent by one of the three methods mentioned above is completed.
