Plain English Summary
Background and study aims
Patients often feel anxiety prior to undergoing surgery. The reason for the anxiety can be both anesthesia used to numb the pain and the actual surgery. The preoperative anxiety that patients have can cause side effects. It is important for the reasons of anxiety to help them in future operations. The aim of this study is to investigate the preoperative patient anxiety and patients fear of anesthesia.
Who can participate?
Adults aged 18 to 95 who are scheduled to undergo elective surgery.
What does the study involve?
Participants are asked to fill out a short questionnaire at the anesthesia clinic about their feelings of anxiety prior to undergoing anesthesia. They are asked if they had received anesthesia before, if they have surgical briefing, and the cause of their anxiety.
What are the possible benefits and risks of participating?
The potential benefit is we can decrease participants anxiety with our interviews. There are no side effects of participating to our study.

Preoperative anxiety and patients' fear of anesthesia
Interviews with the patients are performed when they came to anesthesia clinic for preoperative examination, under the supervision of a specialist anesthetist.
For the study, The Amsterdam Preoperative Anxiety and Information Scale (APAIS), which comprises 6 statements, is used. The answers are evaluated in two scales; the anxiety score and the desire for information score. Anxiety score was obtained by calculating the total scores assigned to the expressions " I am worried about the anesthesic", "The anesthesic is on my mind continually", "I am worried about the procedure", "The procedure is on my mind continually", to measure the patient's level of anxiety regarding the anesthesia and surgery. Desire for information score is obtained by calculating the total scores assigned to the expressions "I would like to know as much as possible about the anesthesic " and "I would like to know as much as possible about the procedure “to measure the patient's level of desire for information regarding the anesthesia and surgery. Higher scores indicate higher levels of anxiety and desire for information. Answers to the statements were evaluated with Likert Scale. (1-Not at all… ,5-Extremely).
In addition, participants are asked whether they had received anesthesia due to any reason, if so, the type of anesthesia, and whether they received surgical briefing. Which anesthetic method recommended to the patient for the surgery they will undergo in the preoperative anesthesia clinic is recorded. Then, participants are asked about the cause of their anxiety regarding the anesthesia.
Primary outcome measure
1. Demographics is measured using the patient notes at the preoperative anesthesia visit
2. Type of anaesthesia patient notes is measured using at the preoperative anesthesia visit
3. Prior experience with anaesthesia patient interviews is measured using at the preoperative anesthesia visit
4. Anxiety regarding anaesthesia is measured using APAIS (Amsterdam preoperative anxiety and information scale) at the preoperative anesthesia visit.
Secondary outcome measures
There are no secondary outcome measures.
