Does the Desire to Know about Information Related to Anesthesia and Surgery Differ according to the Coping Style Classified by the Amsterdam Preoperative Anxiety and Information Scale?

Abstract

Background: High monitors are patients who require information on anesthesia and surgery and generally carry out active searches. These patients will benefit from more information related to surgery preoperatively whereas low monitors will benefit from less detailed information. This study examined whether or not patients' desire for information related to anesthesia and surgery differ according to their coping style classified by the Amsterdam Preoperative Anxiety and Information Scale (APAIS). Methods: 465 patients were asked to fill out the questionnaires in APAIS, State-Trait anxiety inventory (STAI) and also to mark their perception on a 10 cm line in a visual analog scale (VAS). The APAIS with the other subjective measurements of anxiety were evaluated according to their gender, ASA class, past history of surgery and degree of education. Thirteen questionnaires were evaluated according to their coping styles. Results: High monitors wanted to know all 13 questions compared with low monitors, whereas low monitors preferred not to know (P ＜ 0.05). The APAIS has a significant relationship with the VAS and STAI (P ＜ 0.05). Women, patients with no prior history of surgery, and patients with ASA 2 were significantly more anxious than men, patients with a prior experience of surgery and ASA 1 patients, respectively (P ＜ 0.05). The VAS and APAIS were in good agreement in defining patients as anxious and there were significant correlations between the two instruments (P ＜ 0.05). Conclusions: The APAIS can be used as an efficient tool for identifying patients who are particularly anxious or require information.
