Sponsored by Stony Brook University · Observational
The goal of this observational study is to understand how fear and anxiety felt by anesthesia-naive patients compares before versus after their scheduled surgery. Patients who are scheduled to undergo a low-risk surgery/procedure and have never had anesthesia before will be asked to:
Patients that fit the inclusion/exclusion criteria and consent to the study will fill out a paper survey that is an adapted version of the Amsterdam Preoperative Anxiety and Information Scale (APAIS) along with additional questions related to anesthesia anxiety for secondary analysis. 7 days (+/-72 hours) after the patient's surgery, they will complete a follow-up survey over the phone that is an adapted version of the APAIS. Results will be recorded on paper and then uploaded into REDCap for data analysis.

Differences in anxiety scale scores pre- and post-operatively in anesthesia-naïve patients
Participants will be given 2 scores based on their pre-operative survey and their post-operative survey. The change in anxiety score will be evaluated.
Time frame: From enrollment until 7 days (+/-72 hours) post-operative
Determining if there is an association between a pre-operative desire for information related to anesthesia and the post-operative reality of the individual subject's anesthesia experience.
This data will be collected from the pre-operative and post-operative survey questionnaires and evaluated for correlation.
Time frame: From enrollment until 7 days (+/-71 hours) post-operative
Comparing the frequency of specific fears of events pre-operatively versus the post-operative reality of the individual subject's anesthesia experience.
This data will be collected from the pre-operative and post-operative survey questionnaires and will be evaluated.
Time frame: From enrollment until 7 days (+/-71 hours) post-operative
