Effectiveness of pre-anesthetic video information on patient anxiety and economical aspects

BACKGROUND: Adequate preoperative information can lessen patient anxiety. Delivering sufficient information during a personal interview, however, is time consuming, and therefore a relevant economical aspect. We investigated whether video information given to the patient before the pre-anesthetic interview has an influence on the patient's anxiety and the duration of the interview. METHOD: We randomized 302 patients undergoing different types of anesthesia. In all, 151 patients watched a short video with general information about the anticipated anesthesia procedure. Afterward, all patients had a standard pre-anesthetic interview. Patients' anxiety and satisfaction with pre-anesthesia care were assessed after the interview using a visual analogue scale. The duration of the interview was documented. Student t-test and P < 0.05 for differences between the groups. RESULTS: There was no difference in gender, age, ASA physical status, previous anesthesia experience, and the planned anesthesia procedure between the two groups. No difference in anxiety and satisfaction with pre-anesthesia care was observed. The duration of the pre-anesthetic interview was also not different between the groups. DISCUSSION: Preoperative multimedia information did not reduce anxiety or increase the patient satisfaction undergoing anesthesia. The video containing general information did not save time in the pre-anesthetic interview.
