What this trial studies

Adults scheduled for low-risk surgeries who have never had anesthesia will complete an adapted Amsterdam Preoperative Anxiety and Information Scale (APAIS) paper questionnaire in the perioperative setting. They will be contacted by phone 7 days (±72 hours) after surgery to complete the adapted APAIS again and answer additional anesthesia-anxiety questions. Responses will be recorded on paper and then entered into REDCap for analysis of pre- versus post-operative anxiety patterns. The study is observational and does not change clinical care.

Who should consider this trial

Good fit: Adults (18+) who are English-speaking, not pregnant, scheduled for low-risk surgery or procedure, and receiving anesthesia for the first time are ideal candidates.

Not a fit: Patients having high-risk or cancer-related procedures, those under 18, pregnant, non-English speakers, or those who develop postoperative mental status changes are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, this could help clinicians identify and better support first-time anesthesia patients who are likely to experience high perioperative anxiety.

How similar studies have performed: The APAIS and similar questionnaires have been widely used to characterize preoperative anxiety, so the method is established though focusing specifically on anesthesia‑naïve patients is less common.
